Appendix E — The Owner's Companion: For Owners, Developers, Facility Managers, and Homeowners

Read this first

You do not need to have read anything else in this book. This appendix stands alone.

It is written for the person who is about to spend a great deal of money on a building — a developer, a hospital administrator, a school board member, a church building committee, a business owner adding a warehouse, a facilities director, or a couple about to open up the back of a sixty-year-old house. You are intelligent, you are busy, and somewhere underneath the excitement there is a specific, reasonable fear: that you are about to be taken advantage of by people who do this every day, in a vocabulary you do not speak.

So let me be straight about who is writing this. I am a general contractor — twenty-two years, commercial work. I am on the other side of the table from you, and everything else in this book is written to make people like me better at negotiating with people like you.

Read this appendix with one question in mind: where is he protecting his own side? I have tried hard not to, and I have deliberately included the places where the industry's ordinary, legal, everyday practice works against you. There are several. Some of them are things I have done. If a sentence in here sounds written to make contractors look good, distrust it.

Three things to carry before we start:

  1. The number in your head is almost certainly the construction cost, and construction cost is typically 65% to 85% of what the project will actually cost you.
  2. You will cause more delay than you expect, through decisions you did not make on time. This is the single largest owner-caused source of cost and schedule damage on projects of every size, and it is entirely within your control.
  3. Almost every expensive argument on a construction project was created months earlier by a sentence somebody did not write down.

This appendix is not legal advice. See §E.13.


E.1 Before you build anything

E.1.1 Is construction actually the answer?

The cheapest square foot is the one you do not build. Before you commit, put five alternatives on one page and price them honestly.

Option What it costs What it costs that is not money
Do nothing / defer Zero capital; rising maintenance The problem worsens and the price of fixing it rises with construction cost indices
Reorganize what you have Furniture, process change, a small fit-out Political capital. Somebody loses an office. Often the highest-return option and the hardest to sell
Lease or buy existing Rent or purchase plus fit-out Less control, faster occupancy, no construction risk. Frequently right, rarely exciting
Renovate Less per square foot than new, with far more unknowns Unknowns behind walls, phasing around occupants, code triggers
Build new The most capital, the most control Two to four years of your attention

The trap in that table is renovation. Owners choose it because the per-square-foot number looks better, and sometimes it genuinely is. But a renovation buys a building whose condition nobody fully knows, and it frequently triggers code upgrades — accessibility, fire separation, energy, structural, sometimes seismic — that were in nobody's budget. Budget for investigation before you budget for construction: opening walls, testing for hazardous materials, scanning slabs, and paying a code consultant to tell you what your scope of work triggers.

E.1.2 Program before design

A program is the written description of what has to happen inside the building. Not what it looks like — what it does. Room by room: what activity, how many people, what equipment, what hours, what it must be next to, what it must be far from, what it needs in power, air, water, data, light, and acoustic separation.

An architect handed a program designs your building. An architect handed a vague ambition designs a beautiful building for an operation you do not run, and you discover the mismatch in month nine of construction, when fixing it costs forty times what it would have cost on paper.

Write it with the people who will actually work in the building, then have somebody adversarial read it. A program is done when a stranger could read it and tell you what the building is for.

E.1.3 The budget that is not the construction cost

Here is the most common and most expensive misunderstanding in this business, and it is not a contractor's fault.

You have a number in your head. Call it $47 million, or $6.8 million, or $286,000. That number is almost always the construction cost — what you will pay a contractor to build the thing. Your project will cost substantially more, because a construction contract does not include the people who designed it, the equipment that goes in it, the fees to be allowed to build it, the money to pay for surprises, or the cost of moving in.

This is the total project budget for the Northgate Outpatient Pavilion — a 132,000 square foot medical building that runs through this book as a worked example and which, like everyone and everything else in these pages, is an illustrative composite rather than a real project. The construction contract was $47,500,000. The project was $61,000,000.

Line Amount Share
Construction contract (the guaranteed maximum price) $47,500,000 77.9%
Design and engineering fees (architect, structural, mechanical/electrical/plumbing, civil, landscape, specialty consultants) $3,610,000 5.9%
Medical equipment (imaging, surgical, sterile processing) $2,850,000 4.7%
Owner's contingency (≈5% of construction) $2,375,000 3.9%
Furniture, fixtures, and equipment (FF&E) $1,240,000 2.0%
Owner-furnished IT, low-voltage, security, and signage $840,000 1.4%
Permits, plan review, utility connection and impact fees $735,000 1.2%
Owner's representative and program management $520,000 0.9%
Legal, owner's insurance, and financing cost during construction $486,000 0.8%
Testing, special inspection, and materials laboratory $296,000 0.5%
Commissioning agent $265,000 0.4%
Moving, relocation, and staff training $283,000 0.5%
TOTAL PROJECT BUDGET $61,000,000 100%

💰 Money check. Construction is 77.9% of that budget. Walk into the board meeting with $47,500,000 approved and call it the project budget, and you are $13,500,000 short — and you find out in pieces, over two years, each piece arriving as a surprise that makes you look like you had not planned.

The rule of thumb, and its limits. Divide construction cost by something between 0.65 and 0.85 to get a first cut at total project cost. Where you land depends on the project type:

Project type Construction as a share of total project cost
Simple shell building on land you already own 85–90%
Municipal or civic building 78–85%
Commercial building with a full fit-out 72–82%
Healthcare with major medical equipment 70–80%
Laboratory or research facility 60–75%
Custom residential renovation 65–75%

Those are magnitudes I have watched, not published statistics. Do not use them as your budget. Use them to spot a missing category, then build your own line by line with a name next to each line.

The five categories owners most often forget entirely: the owner's contingency (§E.6 — carry none and you will exceed your budget); FF&E, which is almost never in the construction contract; moving and interim operations, including the productivity you lose running a split operation; testing and special inspection, which in most U.S. jurisdictions the owner hires and pays for, not the contractor; and utility connection and impact fees, which can be enormous and are set by agencies that do not care about your budget. Find that last one out early, in writing.

E.1.4 The three numbers you must be able to say out loud

Before you hire anybody: your total project budget (and whether it is a ceiling or a target); your construction budget (the piece a contractor will price); and the date you must be in the building, and what happens if you are not.

That third one is not a preference. It is a number. On Northgate the owner's interim clinic lease expired October 1 of Year 2 at $118,000 per month. That single fact drove the delivery method, the schedule, the liquidated damages, and a $168,000 acceleration decision eighteen months later. An owner who cannot answer "what does a month late actually cost me?" cannot make any of the decisions in this appendix well.


E.2 Who you will hire, and what each one actually does

Role What they do Works for Not responsible for
Architect Designs the building, coordinates the engineers, produces drawings and specifications, administers the contract on your behalf, reviews submittals, certifies payment You Means and methods, construction safety, the contractor's schedule, and — in most contracts — guaranteeing cost
Structural, mechanical, electrical, plumbing, civil engineers Design the systems; usually subconsultants to the architect The architect Coordinating with each other any better than the architect makes them
General contractor (GC) Holds the construction contract, buys and manages subcontractors, controls the site, owns safety, delivers for the contract price Itself, under contract to you Design adequacy, your decisions, your equipment vendors
Construction manager at risk Advises during design, then converts to builder with a capped price Itself, under contract to you Same as a GC, plus whatever its price assumptions excluded
Construction manager as agent Manages the project for you; holds no price risk and no trade contracts You The price. That stays yours
Subcontractors Perform the trades — typically 20 to 40 firms The GC/CM, not you Talking to you. They usually cannot, and you should not encourage it
Owner's representative Your professional, translating and protecting your interests day to day You Directing the contractor's means, methods, or safety
Commissioning agent Verifies the systems you paid for actually work as designed You, directly Designing or building them
Testing laboratory / special inspector Independently tests concrete, soils, welds, fireproofing You, directly, in most jurisdictions Quality control, which belongs to the contractor
Geotechnical engineer Investigates the ground and tells you what is down there You Guaranteeing what is down there
Attorney Reviews and negotiates contracts; advises on notice, claims, liens, disputes You Being cheap. Use them narrowly and early

Two of those rows deserve rereading. The commissioning agent works for you, directly — hired by the contractor, they are grading their employer's homework. The testing laboratory works for you, directly — independent testing is how you find out whether the concrete met strength and the welds passed, and in most U.S. jurisdictions the building code's special inspection provisions already contemplate the owner engaging it.

E.2.1 When you need an owner's representative

The short answer: sooner than you think, and almost certainly if you do not build regularly.

An owner's rep (sometimes "program manager," sometimes an agency construction manager) is a construction professional whose only client on your project is you. They read the cost model, sit in preconstruction, review pay applications, run the change process, keep the decision log, and tell you what the room just agreed to when the room was speaking in acronyms. Typical cost: 1% to 3% of construction value. On Northgate, $520,000 — about 1.1%.

💰 Money check — is 1.1% worth it? Northgate's change orders totaled $2,094,200, of which $1,284,000 was the owner changing her mind and $810,200 was design errors, differing site conditions, and a code official's interpretation. A rep who prevents, defers, or correctly prices a quarter of that has paid for herself twice. And that is the small part. The large part is that she is the reason the guaranteed maximum price was set against 85%-complete drawings instead of 50%, which is worth more than every change order on the job combined.

You need one if you build less than one significant project every three years; if your project is over roughly $2 million and you have no construction professional on staff; if you are using any open-book method, because an open book you cannot audit is a burden with a brochure attached; if your board or lender will ask questions you cannot answer; or if the job must be phased around an operation that stays open. You probably do not if you have a real internal construction group, or the project is small and conventional and your architect is genuinely able to administer it.

Hire them before the architect, or at the latest before the contractor. An owner's rep brought in during construction to fix a problem is an expensive form of therapy. Brought in during programming, they change the outcome.

⚠️ A warning about your own conduct. There is a line between requiring safety and directing it. Requiring a written safety plan and its enforcement is normal and correct. Standing on a deck telling an ironworker how to tie off is different, and in some circumstances it pulls you into duties that were not yours. Err toward: "I am telling your superintendent what I saw. He will tell his people what to do about it."


E.3 How to choose a delivery method

"Delivery method" means the structure of who has a contract with whom, and when the builder shows up.

Method In one sentence You contract with Builder arrives Price certainty
Design-bid-build Finish the drawings, take bids, award to the low bid Architect and contractor, separately After design is 100% done Highest — but latest
Design-build One company designs and builds it One design-builder At the very beginning High and earliest — but only against your written requirements
CM at risk Hire the builder early as an advisor, then convert them into the contractor with a capped price Architect and construction manager, separately During design Good, mid-design
CM as agent Hire a manager to run it; you hold every trade contract yourself Architect, manager, and every trade (8 to 30) During design, as your advisor Lowest — you learn the price package by package

E.3.1 The four questions that actually decide it

1. How complete is your design, and how settled are your requirements? Drawings finished and users done changing their minds — design-bid-build. Take the competitive price; it is defensible and often genuinely lowest. Requirements still moving because your operators are still figuring out how they work — do not choose design-build, where every change after the criteria are signed is negotiated with a company holding the design, the price, and the schedule at once.

2. How much price certainty do you need, and when? If you need a hard number before the design is finished — a board vote, a bond issue, a loan closing — you need CM at risk or progressive design-build. Those are the only structures that produce a real capped price against incomplete drawings. Design-bid-build produces the price on bid day, at the very end.

3. How fast do you need it? Design-bid-build is strictly sequential: design, then bidding, then award, then construction. On Northgate the sequential path was modeled at 223 additional calendar days — about 7.3 months later, once you added the extra design time, the bid period, award and bonding, and a longer construction duration. At $118,000 a month of interim clinic lease, that was $861,400, before a dollar of deferred revenue. Which is why the owner chose CM at risk on a contract that looked $1.65 million more expensive on paper.

4. How much of your own time can you give this? Ranked from least to most owner effort: design-build, design-bid-build, CM at risk, CM as agent. A method you cannot administer is the wrong method, however superior it is in theory.

E.3.2 Low bid is not the same as low cost

This is the section where you should be most suspicious of me, because "don't just take the low bid" is exactly what a contractor would say. So here is the mechanism rather than the opinion.

Sealed bids on a complete set of drawings are a competition, and the winner is structurally the bidder who carried the least money for risk — either because they are genuinely more efficient, or because they made a mistake, or because they read an ambiguous detail optimistically while everybody else read it conservatively. All three produce the same low number, and on bid day you cannot tell which one you got.

The signal is the spread. Here is a bid tab from this book's second worked project, a $22.4 million elementary school:

Bidder Bid Over low
Low bidder $22,400,000
Second $22,710,000 +1.4%
Third $23,050,000 +2.9%
Fourth $23,480,000 +4.8%
Fifth $24,120,000 +7.7%
Sixth $24,890,000 +11.1%

An 11.1% spread on a fully designed building means six contractors read your documents six different ways. A tight spread (2–4%) means everybody priced the same building. A wide spread means the low bidder resolved every ambiguity in the cheapest direction — which is not the direction your architect intended.

What happens next is arithmetic, not malice. General contractors on hard-bid commercial work operate on net margins commonly in the low single digits — often 1.5% to 3%. A contractor who bid $22.4 million is playing for roughly $450,000 of profit. When they hit a conflict in the documents, they cannot absorb it, so their only recovery is the change order and then the claim.

On that same school, a coordination conflict between the structural and mechanical drawings in the gymnasium produced a claim of $214,000 and 21 days. Eleven months later it settled for $96,000 and zero days. The contractor ate $118,000 — 26% of the whole job's profit — and then, entirely rationally, stopped writing early requests for information. He built to his own interpretation and argued afterward, because asking questions had cost him five weeks and gotten him denied.

That is not a character flaw. That is an incentive structure working as designed, and you built it when you chose the delivery method.

The honest counterweight, which matters just as much: competitive bidding works, and for a conventional building with complete documents it is frequently the lowest total cost, not just the lowest bid. There is no substitute for a real market signal, and for a public agency the bid tab answers every "did you get a fair price" question forever.

Low bid buys you the cheapest way to start the building. Whether it is the cheapest way to finish it depends entirely on how complete and unambiguous your documents are.


E.4 How to choose a contractor

E.4.1 Financial capacity and bonding

A contractor who runs out of money in month eleven is the worst outcome available to you — worse than a high price, a slow schedule, or a difficult personality.

Ask for Looking for The follow-up
Audited or reviewed financial statements, CPA-prepared, three years Positive working capital, reasonable debt, a trend that is not deteriorating "Is this a full audit, a review, or a compilation?" A compilation means nobody verified anything
A surety letter stating aggregate bonding capacity and single-project limit Your project comfortably inside both "What is their unused capacity today, in dollars?"
A bank reference and line-of-credit amount Working capital to fund payroll between your payments "Have they drawn on it in the last year?"
Payment and performance bonds — typically 1% to 3% of contract value A surety's independent judgment that this company can perform "Will you provide 100% payment and performance bonds, at what cost?"

What a bond does. A performance bond obligates a surety — subject to the bond's terms and its own investigation — to arrange completion or pay, up to the bond amount, if the contractor defaults. A payment bond gives unpaid subcontractors and suppliers a claim against the bond, which is a large part of what protects your property from liens (§E.9.3).

What a bond does not do. It does not make a bad contractor good, it does not make you whole quickly — surety claims are slow and adversarial — and a surety's first move is frequently to investigate whether you are in default. A bond is a backstop, not a management plan, and its cost is in your price whether or not it appears as a line item. On anything public, anything large, or anything with a contractor you have not worked with, get them anyway.

E.4.2 Safety record, and what an EMR is

Ask for two things: the experience modification rate and the citation history.

The experience modification rate (EMR, or "mod") is a workers' compensation rating factor. A rating bureau compares a company's actual losses over a three-year experience period against the expected losses for a company of its size and trade mix, and produces a multiplier. 1.00 means the company performed exactly as expected. Below 1.00 is better than expected; above 1.00 is worse.

Three things owners misread. It weights frequency more heavily than severity — ten small claims hurt a mod more than one catastrophic one, which means a company can have had a fatality and a mod under 1.00. Do not use it as a moral scoreboard. It is a company number and it lags — this year's mod reflects claims from roughly four to two years ago, so a company that fixed its culture last year still carries the old number; that is a legitimate argument, and you can check it by asking for current loss runs. And the rating formula varies by jurisdiction — most U.S. states use a common bureau formula, several run their own, a few have monopolistic state funds. The concept travels; the arithmetic does not.

Many sophisticated owners set a hard prequalification cutoff at 1.00, sometimes 0.90. That is defensible and it is also blunt; if you use one, allow a written appeal.

Then ask the question EMR does not answer: "Have you had any willful or repeat safety citations in the last three years, and may I see the citations and your abatement?" Willful and repeat are a different category from serious — they reflect intentional disregard or a substantially similar violation cited before. That is the answer that should stop you.

And ignore the small-project injury rate. Recordable injury rates are normalized per 200,000 hours worked. On a 40,000-hour project one recordable injury produces a rate of 5.00 and zero injuries produces 0.00 — same crew, same program, one slip. A project-level safety rate over a short period is statistical noise. Ask for the company rate over three years, and for what they actually do — see Appendix F.

E.4.3 Backlog, and whether you are a rounding error

Ask: "What is your current backlog, what is your annual volume, and what percentage of your capacity is this project?" You want to be big enough to matter and small enough not to break them. Roughly: under 5% of their annual volume and you may get the B team; over 25% and a problem on your job threatens the company, which sounds like leverage and is a risk to you. Then ask what else they are starting in the same window. A contractor who wins three jobs in one month staffs three jobs in one month, and one of them gets the newly promoted superintendent.

E.4.4 The single most important item: the specific team

The people at the interview are not necessarily the people on your job. They are frequently the company's best presenters.

Require the project manager and the superintendent to be named in the proposal, with résumés, and to attend the interview. Ask them a question the executives cannot answer for them — my favorite is "walk me through the first thirty days on this site" — then watch who talks. Put the names in the contract, with a clause requiring your written consent before either is replaced and requiring a replacement of equal qualification. And ask for the superintendent's last three projects, then call the owners of those specific jobs rather than the company's reference list.

The superintendent runs your building. On a project of any size, that one person's competence will affect your outcome more than the difference between the first and second bidder.

E.4.5 References, asked in a way that produces real answers

References are theater unless the questions cannot be answered with "they were great." Call the owner's representative and the project architect from at least three completed jobs — and call one subcontractor, which almost no owner ever does and which produces the most honest information available.

  1. "What was the final contract sum against the original, and how much of the difference was driven by your changes versus theirs?"
  2. "How many change orders, and how many did you genuinely disagree with?"
  3. "Who was the superintendent, and would you take that specific person again?"
  4. "Tell me about the worst month of the project. What happened, and how did they behave?"
  5. "What was the thing they got wrong, and how did they handle it?" (Every project has one. A reference who cannot name it is not being candid.)
  6. "How long after substantial completion did the last punch item close?"
  7. "When did you get your O&M manuals, as-built drawings, and warranties — and did you have to chase them?"
  8. "Did their subcontractors get paid on time? Did any of them call you?"
  9. "Was the schedule they gave you at the beginning the schedule they actually ran, and did they update it honestly when it slipped?"
  10. "Would you hire them again for the same project? Would you hire them for a harder one?"

And the one with the highest value per second spent, asked of every reference:

"What should I watch on this project that I would not think to watch?"

Write down every answer. Patterns emerge in about four calls.

E.4.6 Qualifications-based selection, and its honest limit

Qualifications-based selection (QBS) means you rank firms on capability — past performance, the specific team, technical approach, schedule, management plan — and negotiate price with the top-ranked firm rather than awarding to the lowest number.

For anything complicated it is usually the better structure, for a mechanical reason: when the design is incomplete there is no meaningful price to compare. Four prices against four different interpretations of an unfinished building is not a competition; it is a guess dressed as a bid tab.

The honest limit: QBS with no price discipline is exactly how costs drift upward, quietly, across successive projects, because nobody is testing the market. You must replace market competition with three things, and use all three. An independent estimate — your own cost consultant prices the same drawings in parallel, and where the two differ by more than a few percent somebody explains why line by line. (On Northgate the owner's consultant came in at $46.9 million against the CM's $47.5 million; the reconciliation meeting took six hours and was worth every minute.) Open-book competitive subcontractor bidding, with the bid tabs visible to you — the competition has not been removed, it has moved from one contest among general contractors on bid day to twenty-five contests among subcontractors during buyout, held under your eye. And a savings split worth having (§E.5.4).


E.5 Understanding what you are signing

E.5.1 The pricing structures, plainly

Structure The contractor promises You are exposed to Right when
Lump sum One price for everything shown, whatever it costs them Only your own changes Documents complete, market competitive
Guaranteed maximum price (GMP) Actual cost of the work plus a fee, capped; books open to you Your changes, design errors, differing site conditions, allowance overruns Documents incomplete but you need a cap — and you can audit
Cost-plus, fixed fee To build it well; the fee is a stated dollar amount that does not grow All of it. There is no cap Scope genuinely undefined. Convert to a GMP as soon as the design supports it
Cost-plus, percentage fee Nothing useful to you All of it — plus a fee that grows when the cost grows Almost never. Emergencies, with tight audit rights
Unit price A price per measured unit of work Quantity variation — you pay for what is installed Quantities are the real unknown and the work is measurable: earthwork, utilities, paving

⚠️ On the percentage fee. If the fee is a percentage of actual cost, every dollar of overrun pays the contractor a few cents. Nobody consciously decides to waste your money; what happens is a thousand small decisions where the cheaper option requires a hard conversation and the expensive one does not, and the contractor's own economics never push back. Insist on a fee stated in dollars. It costs them almost nothing to agree and it removes the entire problem.

E.5.2 What a guaranteed maximum price actually guarantees

A guaranteed maximum price guarantees the contractor's exposure. It does not guarantee your cost.

What is guaranteed: for the scope defined in these documents on this date, the contractor will not charge you more than this number, and if it costs them more, they pay the difference. That is a real, enforceable, balance-sheet-threatening promise, and it is why the fee on a GMP exceeds a hard bidder's markup.

What is not guaranteed is your total spend, because you keep the right to change your mind, and the change mechanism is one-directional. Owners issue changes to add a procedure room, upgrade a finish, accept a condition the soils report missed, fix a coordination error, or satisfy a building official. No clause says "if you change your mind less than expected, you get a rebate."

Here is what actually happened on Northgate — a well-run job, a competent owner, a written change-management protocol, and nobody behaving badly:

Category Changes Amount Time granted
Owner-directed scope changes 11 $1,284,000 4 CD
Design clarifications — no cost 19 $0 0
Design errors and omissions 7 $416,500 4 CD
Differing site conditions 3 $238,000 5 CD
Regulatory / code-official interpretation 2 $94,500 0
Allowance reconciliation, net 4 $61,200 0
Totals 46 $2,094,200 13 CD

Final contract sum: $47,500,000 + $2,094,200 = $49,594,200 — 4.4% above the guarantee.

Read the categories again. Only $1,284,000 of $2,094,200 — about 61% — was the owner changing her mind. The rest was design errors, ground conditions, and a code official. None of those is your fault in any moral sense. All of them are your risk under a standard GMP, because the contractor did not draw the building, did not write the soils report, and does not employ the building official.

That owner did not go over budget. She went over the guarantee, and she had planned for it, because she carried roughly 5% of construction value as owner's contingency outside the contract (§E.6).

💡 What to say in the meeting. Say this yourself, before anyone else does: "I understand this caps what you can charge me for the work in these documents. I understand three things will move it — me changing my mind, the documents being wrong, and the ground being different than the report said. I want a written protocol for all three." A contractor who flinches at that sentence has told you something useful.

E.5.3 The clauses that matter most to you

Full treatment of twenty-five clauses is in Appendix G. These decide your money.

Clause What to look for, as the owner
Changes How is a change priced — negotiated, unit price, cost plus a stated percentage? Get the markup percentages into the contract, and state what base each applies to, or you negotiate markup on every change forever
Construction change directive Your right to order work to proceed before the price is agreed. You want this — it prevents your schedule being held hostage over a disputed price. See §E.7.3 for what you owe when you use it
Allowances Each must state the scope or quantity covered, the unit price, and whether it includes overhead, profit, and general conditions. One sentence prevents a very expensive argument
Contingency, and who owns it The contract must say what it may be spent on, who authorizes a draw, what reporting you get, and what happens to the unspent balance
Savings split See §E.5.4. Do not give this away
Liquidated damages A stated daily amount for unexcused late completion — see below
Retention The percentage withheld, when it reduces, when it is released. Retention limits and release timing are set by statute in many U.S. states and vary substantially
Notice requirements They cut both ways. The contractor owes you notice of claims within a short window — and you frequently owe notice too, and your architect owes response times. Calendar every one
Warranty and the correction period Two different things. See §E.10.6
Consequential damages waiver Both parties waive lost profits, lost revenue, lost use, financing costs. This is a large protection for the contractor. If your building's delayed revenue dwarfs the contract value — a hospital, a hotel, a plant — you are waiving your biggest number, and liquidated damages become your only recovery
Dispute resolution and venue Negotiation → mediation → arbitration or litigation. Arbitration is usually faster and private; litigation gives appeal rights and broader discovery. Check the venue clause — a dispute in a distant state costs you before it starts

On liquidated damages, three things owners get wrong.

First, they must be a reasonable pre-estimate of your actual loss, made at the time of contracting. A number set as a punishment rather than an estimate of loss is, in most U.S. jurisdictions, unenforceable — and the specific test varies by state. So do the arithmetic and keep it. Northgate's $5,500 per calendar day was built from interim leased clinic space $2,050 + duplicated staffing and patient transport $1,300 + deferred clinical margin $1,450 + financing carry $700. That build-up is what makes the number defensible.

Second, they are usually your exclusive remedy for delay damages. That protects the contractor by capping an otherwise open-ended exposure. If your real exposure is much larger than the daily rate, you have capped yourself.

Third, a liquidated damages clause without a working time-extension mechanism is a trap for you, not for them. Courts in many jurisdictions will not enforce liquidated damages against a contractor that the owner itself delayed. If you want the clause to hold, administer time extensions fairly.

E.5.4 The savings split, and why not to trade it away

Under an open-book GMP, an unspent balance below the cap is shared. On Northgate the split was 75% owner / 25% contractor on unused construction contingency.

💰 Money check. Suppose $400,000 of the $1,320,000 construction contingency goes unspent. You get $300,000 back; the contractor keeps $100,000 — about 5.5% on top of their $1,804,800 fee. Enough that their project manager has a personal, dollar-denominated reason not to spend your contingency casually, and to solve problems cheaply rather than write change orders.

Contractors will sometimes offer a lower fee in exchange for a more favorable split to them, or none at all. That is usually a bad trade, and it is one of the places where ordinary negotiating practice quietly disadvantages owners who do not do this often. The fee is a fixed, known cost. The savings split is the only mechanism in the entire contract that pays the contractor for spending less of your money. Trading it for a quarter point on the fee swaps a permanent incentive for a one-time discount.


E.6 Contingency, honestly

There are three or four different pots of money called "contingency," they belong to different people, and confusing them is among the most expensive mistakes an owner can make.

Contingency Whose money For what Who authorizes a draw
Design contingency Yours, held during design The fact that an unfinished drawing set grows as it is completed. Shrinks as design develops You and the design team
Contractor's contingency (inside a lump sum) Theirs, hidden inside the price Whatever they decide. You will never see it, you paid for it, and you get none of it back Nobody. It is inside the number
Construction / GMP contingency Inside the contract sum — you have agreed to pay it Cost growth within the defined scope: subcontractor default, buyout shortfalls, coordination gaps, minor field conditions. Not scope changes The contractor, usually with a reporting obligation to you
Owner's contingency Yours, held outside the contract Scope changes, design errors, your decisions, and everything the contract's risk allocation puts on you You

The single most common owner mistake in the industry is assuming the contractor's contingency covers scope changes. It does not. That is what yours is for.

E.6.1 How much, and when

Magnitudes, not rules — adjust for complexity and your own risk tolerance:

Design stage Owner's contingency as % of construction
Concept / programming 15–25%
Schematic design 10–15%
Design development 7–12%
Construction documents complete 5–8%
Under contract, construction underway 5–7%, drawn down as risks retire

Northgate carried roughly 5% — $2,375,000 — against $2,094,200 of changes that actually arrived. That is not luck. That is an owner's representative who had seen it before.

E.6.2 Why a project with no owner's contingency will exceed its budget

Not "might." Will.

Look again at the Northgate register. Only 61% of it was the owner changing her mind. The other 39% — design errors, differing site conditions, and a code official's reading of the code — arrives whether or not you are disciplined. It arrives on well-run projects with good architects. It is a property of building things, not a symptom of failure. A budget with no line for it is not a tight budget; it is an incomplete one.

💡 The most expensive saving available. Somewhere in your process, a well-meaning person will look at the contingency line and say: "That's not real work. Can we take it out and put it back if we need it?"

The answer is no, and here is the mechanism. Removing the contingency does not remove the risk. It removes the money to pay for the risk. When the risk lands anyway — and 39% of it will, no matter how disciplined you are — you pay for it by cutting scope under duress, in month fourteen, when the cheap things to cut are already built and the only things left are the lobby, the landscape, the audiovisual package, and the second elevator.

Scope removed in design costs you the scope. Scope removed in month fourteen costs you the scope, plus the design fee to redraw it, plus restocking and rework, plus the schedule, plus the fact that everyone in the building for the next thirty years will notice what is missing. Never let anyone value-engineer the contingency away. If the project does not work with a contingency, the project does not work.


E.7 Your job during construction

You have five jobs during construction, and only five: make decisions on time; speak with one voice; pay on time; watch honestly and ask good questions; write things down. Doing those five well is worth more than any amount of vigilance about anything else.

E.7.1 The decisions only you can make, and the schedule they must be made on

This is the largest owner-caused source of delay on construction projects. Not funding. Not scope. Late decisions.

Here is why it is worse than it feels. Take three extra weeks to select a light fixture and you do not lose three weeks — you lose the fabrication slot. Submittal review happens after your decision, fabrication schedules after approval, shipment after fabrication, and the installation crew was scheduled for a week that has passed and has been given to another job. Three weeks of indecision routinely becomes seven weeks of schedule.

Build an owner-decision log at the start of construction: every decision you owe, the date it is needed, who decides, what it depends on. Back-schedule from the procurement date, not the installation date — ask your contractor for the required decision dates and put them on your own calendar. Decide with the information you have; a decision made Tuesday with 80% of the information beats one made in four weeks with 95%. And put a dollar figure on your own lateness. On Northgate the total daily exposure to a slipped completion was $10,650 per calendar day — extended general conditions plus liquidated damages. When you know that number, the decision meeting behaves differently.

E.7.2 One voice, one named person

Exactly one person on your side may direct the contractor. Name them in the contract, by name and role, with a written limit on what they can authorize without further approval.

This is not bureaucracy. On a job site, an instruction from anyone who appears to speak for the owner tends to get followed — your facilities director, a department head, a board chair walking the site on a Saturday. Every one of them can create a cost, and when it arrives as a change order the argument is not about whether the work was done; it is about whether the person who asked had authority. That argument is expensive, slow, and bad for a relationship you need for another year.

Everyone else routes through the named person. Write it in the contract and say it out loud at the kickoff meeting, in front of the contractor, so nobody can claim confusion later.

E.7.3 Put it in writing. Every time.

⚠️ Read this paragraph twice. A verbal instruction from you creates a cost you will be billed for and an argument you will probably lose.

Not because contractors are dishonest. Because two reasonable people remember a hallway conversation differently, and eight weeks later the only evidence of what was agreed is a cost report on their side and a memory on yours. In that contest the contemporaneous document wins, and where there is no document the outcome is decided by negotiating leverage rather than by what happened.

Here is what that looks like when it goes wrong, from the owner's side.

Northgate's imaging vendor selected a different MRI unit after the price was set. The new unit needed a deeper depressed slab, added structural framing, additional radio-frequency shielding, and a larger electrical feed. The owner's representative — competent, fair, and under real pressure from a clinical department that had already announced an opening date — gave a verbal go-ahead on a Thursday. Her understanding of the cost was "about $60,000." The contractor's assistant superintendent, under his own schedule pressure, let the concrete crew build it Monday. No written directive, no agreed price, no analysis of the schedule effect, and no time-and-material tickets for the first four days.

Item Amount
Owner's verbal understanding of the cost "about $60,000"
Contractor's actual cost incurred $186,400
Cost that could be substantiated with contemporaneous records $121,000
Negotiated settlement, eight weeks later $142,750
Contractor's unrecovered cost $43,650
Time impact claimed 9 calendar days
Time impact granted 4 calendar days

The contractor ate $43,650 and eight weeks of two people's attention. The owner paid $142,750 for something she had understood to be $60,000 — a number she had already reported to her leadership — and spent eight weeks of her own time, her consultant's time, and a measurable amount of institutional credibility arguing about it.

Nobody in that story behaved badly. She was acting reasonably: the vendor decision was made, the crew was there, the schedule was tight, and saying "go" felt decisive and helpful. That is exactly why I am telling you about it. The failure was not a character failure. It was the absence of a piece of paper.

What she should have said, and what you should say: "Yes, proceed — send me a written directive today with your best estimate and your assumptions, and start daily time-and-material tickets signed by my representative in the field starting this morning. We will agree the final price later."

Eleven seconds. Worth about $80,000 to the owner and $43,650 to the contractor.

E.7.4 How to read a schedule update

You do not need to be a scheduler. You need six questions.

  1. "What is the critical path today, and has it changed since last month?" If it moved from structure to mechanical, something important happened.
  2. "How much float is left, and where did it go?" A job consuming float steadily is heading somewhere, even if the completion date has not moved.
  3. "Which activities show negative float?" Negative float means already late. Any is a conversation.
  4. "What did not start last month that was supposed to?" More predictive than what finished.
  5. "What long-lead items are not yet released for fabrication?" This is where schedules die quietly. Ask for the procurement log.
  6. "What do you need from me, and by when?" Every month. Write down the answer.

⚠️ The warning sign: a schedule whose completion date never moves while the work visibly falls behind. That is not a schedule; it is a wish. The recovery is being deferred into a future the schedule does not describe, and one month it arrives all at once.

E.7.5 How to read a pay application

Check What you are looking for
Schedule of values The contract sum broken into line items. Does the mix look sensible, or is mobilization and general conditions loaded beyond what the work justifies?
Percent complete by line Compare against what you saw on the site walk. Drywall at 60% in a building that is clearly 40% drywalled is a question
Stored materials You may be billed for material not yet installed. Verify it exists, is insured, is stored properly, and that title has passed. Photographs and a bill of sale, every time
Retention Confirm the arithmetic and the percentage against the contract, and that any reduction at 50% completion is applied only when earned
Lien waivers Waivers for the previous payment, from the general contractor and every major subcontractor and supplier (§E.9.3)
Certification Somebody signed a statement that the work is complete as represented. That signature has legal weight. Make sure it is signed

The classic pattern to watch for is front-loading — inflated value on early activities so billings run ahead of costs. It is not always dishonest; construction is a working-capital business and the first four months are the hardest. But it means you are financing the contractor interest-free, and that the money to finish the last 10% of the building has already been paid out. Jobs die in the last 10%.

Three specific things to flag: general conditions billed to 100% in month six of a fourteen-month job (supervision and trailers are consumed over time, not up front); a trade billed ahead of the trade it depends on — roofing at 30% when the deck is at 85% means either stored material you have not verified or a percentage that is wrong; and any request to move money out of the closeout, commissioning, and punch line, which funds the hardest part of the job and is the first place a contractor under cash pressure looks. A $340,000 mobilization line on a $6.8 million job deserves a phone call, and a schedule of values with nine lines on a $20 million project deserves a rejection: insist on enough detail to measure against.

E.7.6 The site walk, and the monthly meeting

On a site walk, look at four things in this order. Housekeeping — is the site clean, are walkways clear, materials stacked, debris removed, cords off the floor? This is the best single proxy for how the job is being run. Safety — edges guarded, holes covered, ladders secured, trenches protected? You are not inspecting; you are forming an impression, and if something alarms you, tell the superintendent, not the worker. Manpower against the schedule — how many people are here, and does that match a job that will finish on time? And where the work isn't — an area that should be finished, with nobody in it, is more informative than an area with twenty people in it.

At the monthly meeting, ask these six. Every month. In this order.

  1. "What is the single biggest risk to finishing on time, and what are we doing about it?"
  2. "What do you need from me, and by when?"
  3. "What long-lead items are not yet released, and what is holding them?"
  4. "What changes are pending that have not been priced, and what is your rough order of magnitude?"
  5. "What did we learn this month that we did not know last month?"
  6. "Is there anything you are worried about that is not on this agenda?"

Question six produces more value than the other five combined, and it only works once you have demonstrated over several months that the answer will not be used against them.


E.8 Change orders: telling a fair one from an unfair one

A change order is not a sign of failure. On a project of any complexity a change register of 2% to 6% of contract value is normal, and a project with zero change orders usually means a very simple building or a contractor absorbing costs they will recover somewhere less visible.

Your job is not to prevent changes. It is to tell a fair one from an unfair one, quickly, so the fair ones get paid fast and the unfair ones get a written answer.

E.8.1 What legitimately belongs in the price

Component What it is Fair?
Direct cost Subcontract amounts, material, labor at an agreed rate with an agreed burden, equipment at an agreed rate schedule Yes, with backup
Subcontractor markup The sub's own overhead and profit, per its subcontract Yes, at the stated percentage
Contractor markup The GC's overhead and profit, per the percentages stated in your contract Yes, at the stated percentage — this is why you write them in
Bond and insurance Premiums rise with contract value Yes, at the actual rate, on the added amount only
Time extension Additional calendar days, if the change actually affects the critical path Yes, if demonstrated
Extended general conditions Supervision, trailers, temporary utilities for the added days Yes, if a time extension was granted, at the contract's agreed daily rate
Impact and disruption Lost productivity from working out of sequence, in a congested area, in worse weather, with a stacked crew Yes — genuinely. But substantiated, not asserted

That last row is real, and owners routinely reject it on reflex. When a change forces a crew to work out of sequence, or in a space with three other trades in it, or in December instead of September, productivity genuinely falls and the contractor genuinely loses money that is not in the direct cost. The problem is that impact is also the easiest thing in construction to exaggerate, because the counterfactual is unobservable.

The right posture is not "no impact." It is "show me." Ask for the planned crew and duration versus the actual, the daily reports covering the affected period, the schedule showing the sequence change, and a comparison to a similar unaffected area on the same job. A contractor who can produce that has earned it. One who says "add 15% for impact" has not.

E.8.2 The nine things to challenge

  1. Markup exceeding the contract's stated percentages. Look it up and cite it.
  2. Markup on markup through the tiers — a sub-sub marks up, the sub marks up that, the GC marks up that. Your contract should cap the total.
  3. Quantities with no takeoff behind them. "Approximately 40 linear feet" is not a quantity.
  4. Labor rates that do not match the agreed schedule. Ask for the build-up: base wage, burden, and what is in the burden.
  5. Equipment rates not from the attached schedule. If no rate schedule was attached to your contract, that is a lesson for the next one.
  6. General conditions billed as a lump when no time extension was granted. Extended general conditions compensate for time. No added days, no added general conditions.
  7. Missing credits. Every addition usually deletes something. Ask: "What is the credit?"
  8. Time claimed with no demonstration that the critical path moved. Ask for the analysis.
  9. Scope that was already in the contract — the most common one. Compare against the drawings and specifications, and involve your architect, whose job this is.

E.8.3 What documentation you are entitled to ask for

Subcontractor quotes for the changed work, at minimum for the portions being marked up. The quantity takeoff. The labor rate build-up and its burden components. The equipment rate schedule and the hours claimed. Daily time-and-material tickets, signed in the field, contemporaneously, for any work performed before a price was agreed. The schedule analysis supporting a claimed time extension. And the contract provision under which the pricing method was chosen.

Ask for these in a written change-order procedure at the start of the job, not the first time you are unhappy. A procedure issued at the kickoff meeting — specifying the format, the required backup, the response times on both sides, and the authorization thresholds — is worth more than any negotiating skill you will ever develop.

E.8.4 And now the honest counterpart

An owner who fights every change on principle gets a contractor who prices defensively on the next job — and on this one.

The mechanism is not sentiment. Contractors price risk, and "this owner disputes everything, pays slowly, and negotiates every legitimate change down 30%" is a risk. It goes into the fee, the contingency, the escalation allowance, and the way every subcontractor on the bid list prices your job. You never see it as a line item. You see it as a higher price you cannot explain.

More immediately: on this job you will need favors — a crew on a Saturday, a resequence for your equipment vendor, a temporary certificate of occupancy pushed for a board tour. Those are given freely by contractors who feel fairly treated and priced by contractors who do not.

Triage every change into three buckets on the day it arrives.

Bucket What it is What you do
1 — Clearly ours Legitimate change, reasonable price Approve it fast, within days. The cheapest credibility you will ever buy
2 — Clearly not ours Scope already in the contract, or their own error Reject it in writing, with the specific reason and document reference. Not silence
3 — Genuinely contested Reasonable people disagree on entitlement or amount Negotiate on a schedule. Set a date. Do not let it sit

The most damaging thing an owner does with change orders is not rejecting them. It is not answering them. An unanswered change order sits on the contractor's books as unbilled cost, tightens their cash, and returns as a claim with interest and attitude attached. Answer everything within a stated period, even if the answer is "we disagree, and here is why."


E.9 Paying, and the money mechanics

E.9.1 The payment cycle

A typical cycle: the contractor submits a pay application by a set day, the architect and your representative certify within a stated number of days, and you pay within a stated number of days after that. Northgate's: apply by the 25th, owner pays in 30 days.

Two things about that gap. Your contractor is paying subcontractors and payroll during it, out of their own working capital. And prompt-payment statutes exist in most U.S. states and vary widely in coverage, timing, and interest — some of them apply to you whether or not you have read them.

Pay on time. It is the cheapest thing you will ever do for your project. A contractor waiting on your money slows down, and the slowdown does not look like a slowdown — it looks like a subcontractor who took his crew to another job for two weeks.

E.9.2 Retention

Retention (or retainage) is a percentage withheld from each payment until the work is complete. Northgate: 10% until the job is 50% complete, then 5%. A smaller municipal job in this book runs a flat 5%. It is your leverage to get the last, least interesting 2% of the work finished, and a fund if you have to complete something yourself.

  • Retention limits and release rules are set by statute in many U.S. states and vary substantially. Some cap the percentage, some require reduction at a stated completion point, some require release within a set period after substantial completion, some require escrow with interest. Look yours up before you write a number into a contract.
  • Retention flows downhill. Whatever you hold from the general contractor, they hold from the subcontractors — so the electrical subcontractor who finished in month eight finances your job until month sixteen. This is a real and widely criticized feature of the industry.
  • Consider early release for completed trades. A provision releasing retention to subcontractors whose work is complete and accepted costs you very little leverage and buys real goodwill in your buyout prices.

E.9.3 Lien waivers, and the risk of paying twice

This is the part that can genuinely hurt you, and most owners do not understand it until it happens.

In most U.S. jurisdictions a subcontractor or supplier who furnishes labor or material to your property and is not paid may be able to file a mechanic's lien against your property — even though your contract is with the general contractor and even though you paid the general contractor in full. You can find yourself paying twice for the same work.

Use all of these protections. Collect lien waivers down every tier — not just from the general contractor, but from every subcontractor and major supplier paid with your money; a package covering only the general contractor protects you from the one party who is not going to lien you. Understand the two axes: a waiver is either conditional (effective when the check clears) or unconditional (effective on signature), and either progress or final; the safe pattern is conditional waivers with the application and unconditional waivers for the prior payment before you release the next. Track preliminary notices — in many states a party preserving lien rights must notify the owner early, and those notices are a free list of everybody who could lien you; reconcile your waiver package against them. Require a payment bond where you are worried, so unpaid parties have a claim against the bond; on U.S. public work liens generally cannot attach to public property at all, and federal and state statutes require payment bonds precisely to give subcontractors a remedy instead. And consider joint checks for a specific troubled party — but get advice first, because joint-check practice can create obligations you did not intend.

⚠️ Lien law is state law, and it is unforgiving and highly technical. Deadlines, notice requirements, who has rights, what a waiver form must say (some states mandate the exact form), whether a waiver can be given in advance, and lien priority all vary substantially by state and change over time. Nothing here substitutes for asking a construction attorney in your state, once, at the beginning, for a one-page procedure.

E.9.4 Warning signs your contractor is not paying their subcontractors

Any two of these together warrant a direct conversation: a subcontractor calls you about payment (this almost never happens on a healthy job); a crew stops showing up for reasons nobody can explain clearly; the lien waiver package arrives incomplete, late, or with a different set of parties than last month; you receive a preliminary notice from a supplier you have never heard of, late in the job; the contractor asks to accelerate payment, bills stored material aggressively, or asks to move money forward in the schedule of values; or a subcontractor is replaced mid-job with no clear explanation.

If you see them: ask for a current subcontractor payment report, consider requiring conditional waivers from every subcontractor as a condition of payment, and talk to your attorney about joint checks. Do it early. A contractor's cash problems are far cheaper to address in month seven than in month thirteen.


E.10 Getting your building at the end

The last 5% of a construction project generates a wildly disproportionate share of the frustration, almost entirely because owners do not know what the finish line actually is.

E.10.1 Three different "done"s

Milestone What it means What happens
Substantial completion The work is complete enough that you can occupy and use it for its intended purpose — generally including a certificate of occupancy and any required regulatory approvals Liquidated damages stop. Risk of loss, utilities, security, and maintenance generally shift to you. Retention is typically reduced. The warranty period starts. The punch list is issued
Certificate of occupancy The building official's permission to occupy A regulatory approval from an agency, not a contract milestone. Usually a condition of substantial completion, not the same thing
Final completion Punch closed, closeout documents delivered, training done, final waivers in Final payment and release of remaining retention

On Northgate: substantial completion September 18 of Year 2, certificate of occupancy September 24, final completion November 17sixty days of closeout after substantial completion.

That sixty days surprises every first-time owner, and it is not padding. It is punch work, testing and balancing, commissioning issue resolution, training scheduled around your staff, and a document package that takes real effort to assemble. Put it in your budget and in your move-in plan.

E.10.2 Substantial completion is a negotiation

Because so many consequences attach to it, the date is genuinely contested on many projects. Your contractor wants it early (damages stop, retention reduces). You want it accurate.

Decide the criteria in advance, in the contract. A good definition names the required regulatory approvals, the systems that must be operational and commissioned, the training that must be complete, and — the one people forget — that the remaining work must not interfere with your use of the building. A building you can technically occupy while eleven trades finish around your staff is not substantially complete in any way that helps you.

E.10.3 Commissioning, and why it must start long before the end

Commissioning is the process of verifying that the building's systems actually perform the way the design intended, under real conditions. Not that they turn on — that they work.

The most common owner mistake is treating it as a testing event at the end. It is a process that runs the length of the project:

Phase What the commissioning agent does
Programming / early design Writes the owner's project requirements — a plain-language statement of how you expect the building to perform. Everything else is measured against it
Design and construction documents Reviews the design against those requirements, and makes sure the specifications actually require the testing, documentation, and training you will need. Catches problems on paper, where they cost nothing
Submittals and installation Reviews equipment submittals against the requirements, and verifies installation as it happens — not after it is covered up
Functional testing Tests systems in all operating modes, including failure modes and seasonal conditions
Turnover and warranty Verifies training, documentation, and closeout of every issue on the log — then often returns at ten months to check seasonal performance before the correction period expires

Northgate's field testing started July 20 of Year 2, roughly two months before substantial completion — but the commissioning agent had been engaged since design.

Two rules. Hire the commissioning agent directly — not through the contractor, and ideally not through the architect; they are verifying other people's work and should not report to the people being verified. And hire them during design. One who first appears at substantial completion can produce a report. They cannot produce a commissioned building.

E.10.4 The punch list

It is not a quality program. If the punch list is where you find out the quality is wrong, it is already too late — the work is installed, crews are demobilizing, and your leverage is a small percentage of retention. Quality is managed during construction through mockups, benchmark installations, and inspections. The punch list catches the last 1%.

Run it well: punch by area as areas complete, not in one enormous walk at the end; require a contractor pre-punch before your walk, so your list does not include items their own superintendent would have caught; keep one list, merging your architect's punch, your facilities staff's punch, and the commissioning issues log into a single tracked document with owners and dates; set a closure clock with a date and a real contractual consequence past it; and separate "incomplete" from "defective," which are different problems with different remedies.

E.10.5 The turnover package, and when to demand each piece

This is where owners lose the most and complain the least, because the loss appears three years later when nobody can find the air-handler manual. Demand each item at the time listed — not at final completion, when your only leverage is the last of the retention.

Item Demand it by
Draft operations and maintenance manuals 60% construction complete, so you can review them while it matters
Final O&M manuals, indexed and complete 30 days before substantial completion, as a condition of substantial completion
Record ("as-built") drawings Verified monthly at each pay application; final set at final completion. A set assembled in the last week is fiction
Warranties, with start dates tied to substantial completion, not installation At substantial completion
Owner training, scheduled with your staff, recorded on video, with attendance sheets Before substantial completion
Test and balance report Before functional testing, not after
Commissioning report with every issue closed or formally accepted Before final completion
Attic stock and spare parts specified in the contract Before substantial completion — it disappears otherwise
Keys, keying schedule, and access credentials At substantial completion
Regulatory certificates — occupancy, fire marshal, elevator, health department, backflow At substantial completion
Software licenses, controls passwords, and administrator accounts in your name At substantial completion, in writing, tested
Final lien waivers from all tiers, and consent of surety to final payment With final payment

That second-to-last row is a modern trap worth naming. Building automation, lighting controls, access control, and elevator monitoring all run on software with administrator accounts. If those accounts belong to the installing contractor rather than to you, you have bought a building you cannot fully operate or competitively service. Require the credentials in your name, log in yourself to verify them before final payment, and get the licensing terms in writing.

E.10.6 The eleven-month warranty walk

Most construction contracts include a one-year correction period: for one year after substantial completion the contractor must correct work that does not conform to the contract documents. This is not the same as a warranty — product warranties have their own durations (a roof membrane might be twenty years, a chiller five, a paint job none) and run on their own terms.

The correction period is the one with a cliff at the end of it, and almost nobody uses it. So the day you accept substantial completion, put a calendar reminder at eleven months. Then:

  • Walk the entire building with your facilities staff, your maintenance technicians, and the contractor's project manager.
  • Bring the punch list, the commissioning issues log, and — most valuable — the list of every complaint your staff has made in eleven months. The people who use the building know exactly what is wrong with it.
  • Include a seasonal check. If you accepted in September, the heating system has been through one winter and the cooling system has not been through a summer under full load. Say so in writing and reserve those items.
  • Produce a written list with dates, deliver it before the twelve-month mark, and follow up.

An eleven-month walk routinely produces $20,000 to $100,000 of corrections on a mid-size building that you would otherwise pay for yourself. It costs you an afternoon.


E.11 If you are building or renovating a house

Everything above applies. This section is what is different.

E.11.1 The number you tell your friends, and the number you actually spend

Meet Nora and Ben Aldridge — illustrative, like everyone else in this book. A 1962 ranch house in Rivermont: kitchen, primary bathroom, and a 340 square foot family room addition. They signed with a small, well-regarded remodeler for $286,000 and told everyone the project was $286,000.

Line Amount
Construction contract $286,000
Allowance overruns, with markup (below) $47,668
Owner-directed changes (two added windows, relocated laundry) $18,900
Hidden conditions (obsolete wiring in the opened kitchen wall; an undersized header) $9,400
Designer / architect fees $19,500
Structural engineer $3,200
Permits and plan review $4,800
Interim housing, 4 months at $2,400 | $9,600
Storage $1,300
Furnishings and window treatments not in the contract $16,000
Landscape repair after the addition $5,200
Actual total project cost $421,568

The construction contract was 68% of what they spent. They were not cheated. Nobody lied to them. They budgeted the contract and not the project.

E.11.2 Allowances, and the allowance-overrun conversation

An allowance is a placeholder dollar amount for something you have not chosen yet — cabinets, tile, plumbing, lighting, appliances, flooring. At the end it is reconciled against what you actually bought, and the contract price moves. The Aldridges' contract carried $87,200 in allowances — 30% of the contract.

Item Allowance Actually selected Overrun
Cabinets $34,000 | $51,800 +$17,800
Tile $12,000 | $23,400 +$11,400
Plumbing fixtures $9,500 | $12,900 +$3,400
Lighting fixtures $6,200 | $8,050 +$1,850
Appliances $11,000 | $16,400 +$5,400
Flooring $14,500 | $16,100 +$1,600
Totals $87,200 $128,650 +$41,450

Then the argument. The contract said nothing about whether allowances included the contractor's overhead and profit. He said markup applied to the overrun; they said the allowance was a gross number. They settled at 15% on the overrun — $6,218 — for a total of $47,668.

Every one of those overruns was a free choice, and each felt small in the showroom. Together they were 16.7% of the contract, and they did not buy one additional square foot of house. They bought nicer versions of things already in the contract.

Three rules prevent this. Take the allowance number to the showroom before you sign and ask what $12,000 gets you for this square footage, installed; if the honest answer is "builder-grade," you now know your budget is $23,000 and you can decide with your eyes open. Get every allowance written with its markup treatment stated — one sentence, either way; silence is what costs money. And watch for allowances set low to make a bid look competitive: if one contractor's cabinet allowance is $34,000 and another's is $52,000 for the same kitchen, the second bid may be the honest one. Compare bids on allowance amounts, not just totals, or you are comparing two different projects.

E.11.3 The selections schedule — the number-one cause of cost and delay on custom work

Late decisions cost more on a house than on a hospital, because the crew is small, the schedule is short, and one missing item stalls everything. Before construction starts, build a selections schedule with hard "decide by" dates, back-scheduled from installation with lead time subtracted.

Selection Lead time Needed on site Decide by
Windows and exterior doors 8–12 weeks Week 5 Before construction starts
Cabinets 6–10 weeks Week 12 Week 2
Plumbing fixtures (rough-in dimensions drive framing) 2–6 weeks Week 7 Week 1
Tile 2–4 weeks Week 14 Week 8
Lighting fixtures 3–6 weeks Week 15 Week 8
Appliances (dimensions drive the cabinet order) 4–12 weeks Week 16 Week 2 — with the cabinets
Flooring 2–6 weeks Week 17 Week 11
Paint colors days Week 18 Week 15
Hardware and accessories 2–4 weeks Week 19 Week 14

Two things in that table surprise homeowners. Your windows have to be decided before the job starts. And your appliances have to be chosen with your cabinets, because appliance dimensions determine the cabinet order, and a cabinet order is not a thing you change.

The Aldridges' contract was four months. It took six and a half. Their contractor was not slow. They selected tile in week eleven.

E.11.4 Draw schedules and paying

Residential payment usually runs on a draw schedule tied to milestones rather than monthly percentage-of-completion applications:

Draw Typically at
Deposit Signing — and many states cap this by statute
Draw 1 Demolition and rough framing complete
Draw 2 Rough mechanical, electrical, plumbing complete and inspected
Draw 3 Insulation and drywall complete
Draw 4 Cabinets and tile set
Draw 5 Substantial completion, less retention
Final Punch complete, final inspection, lien waivers received

Never get ahead of the work — if you have paid 70% and 50% is built, you have lost your leverage and taken on the risk. Hold retention, 5% to 10%, until punch is genuinely complete; if your contract has none, ask for it. And get lien waivers, including from major subcontractors and suppliers, with every draw. Yes, on a house. Residential liens are real, and homeowners are the least protected owners in the market precisely because they do not ask.

E.11.5 Living in the house during the work

Be honest with yourself here, because most people underestimate it by about a factor of three.

  • Dust travels everywhere, through a barrier, into closed drawers on the other side of the house. Ask for barriers with zippered doors, negative air with a filtered fan, floor protection on every path, and daily cleanup — in the contract, not as a favor.
  • You will lose a bathroom or a kitchen for longer than the schedule says. Plan where you will cook and shower, and for how many weeks.
  • Set work hours in the contract, plus a policy on music, smoking, parking, and bathroom use. These sound petty and they are the source of most residential friction. Plan for pets and children too: a curious dog and an open exterior wall is a bad afternoon.
  • Price four months of interim housing even if you plan to stay, then decide with real numbers. Many people who intended to stay leave in week three and pay a premium for a last-minute rental.

Residential construction law is not commercial construction law, and both vary by state. Verify these where you live:

  • Contractor licensing is required for residential work in many states, with searchable public registries and complaint histories. Look yours up. Four minutes, and the highest-value four minutes in this appendix.
  • Home improvement contracts are regulated by statute in many states — mandatory contract terms, mandatory disclosures, a required written contract above a dollar threshold, and sometimes a right to cancel within a stated period after signing.
  • Deposit amounts are capped by statute in some states.
  • Mechanic's lien procedure differs for residential property, and several states provide homeowner-specific protections — notice requirements, waiver requirements, or a recovery fund.
  • Arbitration clauses in residential contracts are treated differently in different states.

Do this once: before you sign anything above a threshold you are not comfortable losing, pay a construction attorney in your state for one hour to read the contract. On a $286,000 renovation, an hour of legal review is roughly 0.1% of the project and the best-value money in the budget.

E.11.7 And the bid that is 30% lower

If three contractors quote $310,000, $286,000, and $198,000, the $198,000 bid is not a bargain. It is a different project, or a different set of allowances, or a company that has made an error, or one that intends to make the difference back through change orders — and one of those four is always true. Do not simply discard it: ask them to walk you through it, line by line, against the other two. If they can defend it, you have found value. If they cannot, you have learned something for free — and you have learned how they will behave when a real question arises in month three.


E.12 The ten questions to ask before you sign anything

Print this. Ask all ten out loud, of the contractor and of your own team.

  1. "What is my total project budget, and what is in it besides construction?" If the answer is only the construction number, go back to §E.1.3.
  2. "What exactly is included in this price, and what is specifically excluded?" Ask for the exclusions list in writing and read every line. This is where the surprises live.
  3. "What is guaranteed, and what is not?" If it is a guaranteed maximum price, say the sentence from §E.5.2 out loud and watch the reaction.
  4. "How much contingency is in this number, who controls it, and what happens to it if it is not spent?"
  5. "What are the markup percentages on change orders, and are they written in the contract?"
  6. "What are the allowances, what do they actually buy, and do they include your overhead and profit?"
  7. "Who specifically will run this job — name the project manager and the superintendent — and will you put them in the contract with my consent required to replace them?"
  8. "What decisions do you need from me, and by what dates?" Ask for the list before you sign.
  9. "What are the notice requirements — yours and mine — and what happens if either of us misses one?"
  10. "What is your bonding capacity, your experience modification rate, and may I call three owners and one subcontractor of your choosing — and one of mine?"

And a bonus eleventh, which I would ask above all the others if I were you:

"What is the thing about this project that worries you most, and what would you do about it if it were your money?"

A contractor who answers that specifically and uncomfortably is telling you the truth. One who says "nothing, we've done a hundred of these" has told you something too.


E.13 When to get a lawyer

This appendix is not legal advice, and it cannot be. I am a project manager, not an attorney. Construction law in the United States alone is fifty-plus bodies of state law plus federal law plus local ordinance plus whatever your contract says, and this book is read in countries whose systems differ from all of it. Lien deadlines and procedure, retention limits, prompt-payment requirements, contractor licensing, anti-indemnity rules, the enforceability of no-damage-for-delay clauses, the test for whether liquidated damages are valid, and residential homeowner protections all vary substantially by jurisdiction and change over time.

Get a construction attorney — one who does construction, not a generalist — for these:

Situation Why
Before signing any construction contract above a threshold you set An hour of review is the highest-return money in your budget
Before signing a contract you did not draft, on somebody else's form Especially the supplementary conditions, where a standard form gets bent
The first time you receive a claim, a delay notice, or a demand letter Notice deadlines run against you from the day the event occurred, and they are short
The first time a subcontractor contacts you about payment Lien exposure. Act in days, not weeks
Any time you consider withholding payment or terminating Both are high-risk actions with procedural requirements; doing them wrong converts a good position into a bad one
Any dispute above a number that would genuinely hurt you Set that number now, in advance, while you are calm
Before you sign an arbitration clause with a venue you have not read You are choosing where and how you will fight, before you know what about

And the single most useful thing an attorney will ever do for you: a one-page notice calendar, prepared the week you sign, listing every deadline in the contract that runs against you. It costs almost nothing and it prevents the failure mode that kills more valid positions than any other.

Separately, talk to your insurance broker before you sign and ask one specific question: "Is the obligation I just agreed to actually insured, and by which policy?" An indemnity or a performance guarantee that no policy covers is a promise backed by a balance sheet, and if that balance sheet is thin, you have a piece of paper and nothing behind it.
