Chapter 31 — Further Reading

Ten pointers, all real organizations, standards families, or public records. Where I am not certain of an exact title, edition, or section number, I describe the source rather than invent a citation — and you should hold every author to that standard, including me. Nothing below is legal advice, and none of it substitutes for reading your contract.

1. Your own Division 01 and your own general conditions

What it is: The two documents that actually decide every number in this chapter — the change-order article of your general conditions and the Division 01 sections that govern modification procedures, unit prices, and allowances.

Why read it: Everything in §31.5 is contract-dependent. The markup percentages, whether a second tier gets its own markup, how credits are computed, what backup is mandatory, how long you have to give notice, whether cost and time run on separate clocks, and whether the words "impact" or "cumulative" appear anywhere at all — those are decided in your documents, not in a textbook. Read them with a pen before you price your first change, and write the numbers on a card.

Who it's for: Everyone. If you read one thing on this list, read this one.

2. AIA Contract Documents — the A201 family, and the standard change order and construction change directive forms

What it is: The American Institute of Architects publishes the general-conditions and modification forms used across much of U.S. commercial building. The changes and claims articles of the general conditions define the instruments in §31.2; the standard change order form is the bilateral settlement; the standard construction change directive form is the unilateral instruction to build now and price later.

Why read it: Read the actual documents, not a summary of them. Pay particular attention to the sentence stating that an executed change order constitutes full and final compensation including adjustment of contract time — that one sentence is why "we'll sign the cost now and deal with time later" is expensive — and to the way the directive form fixes a pricing mechanism in advance.

Who it's for: Every project manager and project engineer on private commercial work.

3. ConsensusDocs and EJCDC — the alternative document families

What it is: ConsensusDocs is a coalition-drafted family of standard construction contracts; EJCDC (the Engineers Joint Contract Documents Committee) publishes the family most common on engineer-led utility, water, and civil work.

Why read it: Compare the changes clauses of all three families side by side once, in your career, and you will never again assume you know what "the standard clause" says. The risk allocations genuinely differ — on notice periods, on the treatment of directed work, on the definition of the cost of the work, and on whether consequential or impact damages are waived at all.

Who it's for: Anyone who works for more than one kind of owner. Especially useful for owner's representatives choosing a document family.

What it is: The Association for the Advancement of Cost Engineering publishes a library of recommended practices, including RP 29R-03 on forensic schedule analysis — the most-cited public taxonomy of delay-analysis methods — and companion recommended practices on estimating and proving lost labor productivity. It also runs certification tracks for cost professionals and planning and scheduling professionals.

Why read it: §31.5.4 asks you to insert a fragnet into the accepted current update and call the result evidence. AACE's material is where you learn why that method is respected and the alternatives are not, and it is the vocabulary an owner's consultant will use across the table from you. The productivity material is the rigorous version of §31.5.5, including the honest treatment of when a measured mile is and is not available.

Who it's for: Schedulers, project controls staff, and any project manager who expects to defend a time claim in front of a consultant.

5. The Society of Construction Law Delay and Disruption Protocol

What it is: A widely referenced protocol on delay and disruption analysis published by the Society of Construction Law, a U.K. body. It is not a contract, not a standard, and not binding anywhere — it is a considered statement of good practice that the international construction community treats as a common reference point.

Why read it: It is the clearest free treatment available of the questions this chapter can only introduce: who owns float, how concurrent delay should be handled, what a contemporaneous analysis is worth compared to a retrospective one, and how disruption should be demonstrated. Read it alongside the AACE material and note where the two diverge — the divergence is itself the education.

Who it's for: Anyone working internationally, and anyone who wants the disruption argument stated by people with no stake in your job.

6. MCAA and NECA — where the published inefficiency factors actually come from

What it is: The Mechanical Contractors Association of America and the National Electrical Contractors Association both publish long-standing guidance on labor units and on the productivity effects of change, overtime, stacking of trades, and out-of-sequence work. The MCAA material in particular is the source most often cited when somebody puts a percentage on a disruption claim.

Why read it: Because §31.5.5 tells you these tables are negotiating references and not measurements, and you should not take my word for that — you should read the publishers' own framing of what the factors are and are not. Knowing where the numbers came from, how the conditions are defined, and what the publishers themselves say about applying them is what lets you use a table as a sanity check and refuse to use it as a proof.

Who it's for: Mechanical and electrical contractors pricing impact; general contractors and owners' representatives evaluating impact claims submitted by them.

7. Published decisions of the U.S. boards of contract appeals

What it is: The Armed Services Board of Contract Appeals and the Civilian Board of Contract Appeals decide disputes on federal construction contracts, and their decisions are published and freely available. They are long, factual, and written for a reader who was not there.

Why read it: This is the best free education in existence on why claims win and lose. Find two or three decisions involving a measured-mile or a total-cost disruption claim and read them start to finish. You will see, in detail, exactly which records were persuasive, which were not, how a tribunal handles a baseline period the other side attacks as cherry-picked, and how a contractor who scrubbed its own numbers is treated differently from one who did not. It will change how you keep records on Monday.

Who it's for: Anyone who wants to see the abstractions in §31.5.5 applied to real facts by someone with authority to decide.

8. The federal changes and differing site conditions framework — the FAR clauses and the Contract Disputes Act

What it is: The Federal Acquisition Regulation contains the standard changes, differing site conditions, and suspension-of-work clauses used on federal construction, and the Contract Disputes Act establishes the claim and appeal process. The Miller Act governs payment and performance bonds on federal work.

Why read it: Federal construction contracting is the most heavily documented change-order regime in the country, and its clause language and case law have influenced state and local practice everywhere. Even if you never bid a federal job, reading the differing-site-conditions clause and its two-type structure will sharpen how you read the equivalent provision in a private contract.

Who it's for: Anyone considering federal work, and anyone who wants a rigorous model of how a changes clause can be written.

9. State and local public-agency standard specifications and change-order policies

What it is: State departments of transportation, large school districts, and municipal public works departments publish standard specifications and standing change-order policies — force-account procedures, capped overhead and profit percentages, required record formats, approval thresholds that trigger a board or council vote.

Why read it: This is where you learn how much public work differs from private work, and how much jurisdictions differ from each other. Markup caps, notice periods, prequalification rules, prompt-payment requirements, and whether impact costs are recoverable at all vary by state and by agency and change over time. Never assume the rule you learned on your last public job applies on your next one. Find the current published policy for the agency you are actually working for.

Who it's for: Anyone bidding public work — which, on a hard-bid school like Rivermont Elementary, is the difference between a 32% recovery rate and a fight.

10. AGC of America, CMAA, and CFMA — the practitioner associations

What it is: The Associated General Contractors of America publishes contract documents, subcontract forms, and practical guidance on change management and claims avoidance. The Construction Management Association of America publishes standards of practice covering change management as a defined CM function. The Construction Financial Management Association is where the money side of pending changes — work in progress, over- and under-billing, the cost of carrying unbilled work — is treated seriously.

Why read it: AGC for the flow-down and subcontract-administration mechanics in §31.9; CMAA for a clean statement of what change management looks like as a professional discipline rather than as firefighting; CFMA for the argument in §31.8 that unapproved changes are a cash-flow problem before they are a profit problem, worked properly by people who do it for a living.

Who it's for: Project managers moving toward operations leadership, and anyone who has to explain pending-change exposure to a CFO.

A note on what is deliberately not here

There is a large market in claims-consulting literature that will teach you how to build a bigger number. Some of it is excellent and most of it is written by people who get paid when the number is bigger.

I am not sending you there, because the skill that pays on a real job is the opposite one: keeping records so ordinary and so contemporaneous that no consultant is ever required. The four days of tickets that would have saved Kestrel $19,050 were not sophisticated. They were a clipboard and ten minutes at the end of a shift.

So here is the actual assignment, worth more than any of the ten items above. Go find the last three change orders your company settled below its submitted number, and read the whole file — the notice, the backup, the owner's response, and the settlement. Write down, for each one, the specific record whose absence explains the gap. Do that once and you will never again wonder why this chapter spends so much time on paper.

Then go read your own contract's notice clause and write the two dates on a card.
