Case Study 4-1 — The Conversion Meeting: Setting the Northgate GMP

Kestrel Construction Group, Meridian Health System, and everyone named in this case study are Tier-3 illustrative composites drawn from projects I have worked on. The numbers are internally consistent and realistic, but this is not a record of any single real project.

Setup

Eleven months before notice to proceed, Kestrel Construction Group signed a preconstruction services agreement with Meridian Health System for the Northgate Outpatient Pavilion. Under CM at Risk, that first agreement buys estimating, constructability review, scheduling, VDC coordination, and early trade engagement. It does not commit anybody to build anything. Kestrel was paid a fixed preconstruction fee and had no obligation beyond advice.

That changes today. This meeting converts the relationship into a construction contract by executing a guaranteed maximum price amendment — the moment Kestrel stops being a consultant and becomes the party that eats the overrun.

In the room:

• Ray Alvarez, Kestrel's senior project manager.
• Tomás Reyes, Kestrel's chief estimator.
• Nadia Haddad, Kestrel's VP of Operations. She signs.
• Priyanka "Pri" Sethi, Meridian's owner's representative.
• Meridian's outside construction counsel.
• Dale Whitcomb, project architect at Halvorsen + Pike, on video for the first hour.

The number on the table:

Contract time: 565 calendar days from NTP on March 3, Year 1, to substantial completion on September 18, Year 2. Liquidated damages $5,500 per calendar day. Retention 10% until 50% complete, then 5%. Savings on unused contingency split 75% Meridian / 25% Kestrel.

The design is at roughly 75% construction documents. That is the whole reason this meeting is difficult. Twenty-five percent of the drawings do not exist yet, and Kestrel is about to guarantee a price for the building they will eventually show.

What happens

Meridian's counsel came to the meeting with a list. Three items on it were requests to pull risk inside the guarantee. Kestrel said no to all three — and then negotiated all three, which is a different thing than saying no and going home.

Item 1 — "The imaging suite should be inside the GMP."

Meridian had not selected its imaging vendor. The MRI, the CT, and the interventional suite were all still in procurement, and the vendor selection drives the depressed slab depth, the structural framing, the RF shielding, the chiller load, and the electrical feed.

Pri: "The imaging suite is in the program. It's on the drawings. Why isn't it in the price?"

Tomás: "Rooms are on the drawings. Equipment isn't selected. The slab recess for the unit we've assumed is eight inches. If your vendor's unit needs fourteen, that's a deeper excavation, more structural framing, a different shield package, and a bigger feeder. I can price the room. I cannot price a machine nobody has picked."

Counsel: "Then price the worst case and put it in."

Tomás: "The worst case is about $340,000 across all three suites, and you'd pay for it whether or not it happens. I don't think you want that, and I don't think your board wants me guessing at it."

The compromise was not money. It was a deadline and a protocol.

The GMP amendment carries an owner-furnished-equipment protocol: Meridian commits to final imaging vendor selection and delivery of certified equipment drawings by August 1, Year 1 — which Wei Chen had back-scheduled from the depressed-slab pour date. Meridian's assumed base equipment package is documented by manufacturer and model in an exhibit. Any deviation from that package, or any selection after August 1, is a change to the contract sum and, if it lands on the critical path, to the contract time.

Nobody in that room thought that clause would matter. It is the single most important paragraph in the amendment, and eighteen months later it is the reason change order #14 was a negotiation instead of a lawsuit.

Item 2 — "You should carry all subsurface risk."

Meridian's counsel wanted the differing site conditions clause narrowed and the geotechnical risk moved to Kestrel. The argument was reasonable on its face: Kestrel had the report, walked the site, and priced the work.

Ray: "Fourteen borings. Six point two acres, and it slopes. The north property line is thirty feet from an active clinic that stays open through construction, and nobody at the city can give me a reliable utility record for that strip. I'm not guaranteeing what's under there."

Counsel: "Then price it."

Ray: "I can price a quantity. I can't price an unknown."

That distinction — pricing a quantity versus pricing an unknown — is the whole trade, and it produced the deal:

Unsuitable soils allowance: $285,000, covering up to 3,800 CY of undercut, export, and replacement with imported structural fill, at an agreed unit price of $75.00/CY. Quantities beyond 3,800 CY are a change to the contract sum at the same unit price. Unused allowance returns to Meridian at reconciliation.

3,800 CY × $75.00/CY = $285,000. Meridian now owns the quantity risk and knows the price of it. Kestrel owns the productivity and means-and-methods risk on the work it performs. Both parties know exactly what happens at cubic yard number 3,801, which is the entire point of a well-drafted allowance.

Item 3 — "Delete the escalation allowance."

The $575,200 line drew the hardest pushback. Meridian saw a contractor asking to be paid for a risk it should carry.

Tomás put up one table:

Tomás: "$575,200 divided by $14,200,000 is four point oh five percent. That's what I'm carrying, and I'm carrying it on the fourteen million where raw material moves the price — not on the whole forty-seven five. Steel doesn't get bought until October. If you want me to guarantee an October mill price in February, I have to charge you more than four percent, not less."

The compromise made the allowance genuinely owner-favorable. The $575,200 stays inside the GMP, but it is drawn only against documented, indexed increases on the four named commodity categories, supported by the subcontractor's or supplier's own quotation history. And any unused portion returns to Meridian 100% — it sits outside the 75/25 savings split, because it is a reserve, not a savings opportunity.

Meridian's counsel wrote that sentence herself. It was the best thing anybody did all day.

The fourth negotiation: the extended general-conditions rate

The last real fight was over a number that does not appear in the build-up at all: the daily rate Kestrel gets paid if Meridian delays the job.

Kestrel proposed $5,150 per calendar day, computed straightforwardly:

$2,900,000 ÷ 565 CD = $5,132.74/CD, rounded to $5,150/CD

Meridian's counsel ran her own analysis and pushed back hard. Not all of the $2,900,000 is time-related, she argued. Final cleaning, small tools, mobilization, and permits do not cost more because the job runs twenty days longer. Her time-related figure was about $3,560/CD — nearly $1,600 a day less.

She was analytically correct and she still agreed to $5,150. Here is what she got for it:

The $5,150/CD rate is the exclusive remedy for time-related overhead on compensable delay. No home-office overhead formula on top. No separate unabsorbed-overhead claim. No lost-productivity claim folded into a delay claim.

Meridian bought certainty and closed off an entire category of claim. Kestrel bought a generous, undisputed daily number it never has to prove with a forensic accountant. Both sides gave something real.

Nadia signed at 4:40 p.m.

Analysis

Why Kestrel's three refusals were correct, and not merely self-interested. A contractor can guarantee two things: what it can count, and what it can control. Kestrel could count the drawings and control its own means and methods. It could not count an unselected MRI, could not control the soil under an unsurveyed property line, and could not control a commodity market eight months out. Guaranteeing any of the three would have required pricing a worst case — $340,000 for the imaging package alone — that Meridian would have paid whether or not it ever happened. Refusing to guarantee an unknown is not the contractor protecting itself at the owner's expense. It is the contractor declining to sell the owner expensive insurance against a risk the owner is better placed to manage.

Each compromise did the same structural thing: it converted an unknown into a defined quantity with a known price and a named trigger. The imaging protocol converted "we don't know what the vendor will pick" into "here is the assumed package, here is the deadline, here is what happens if either changes." The soils allowance converted "the ground might be bad" into "3,800 CY at $75.00, and here is what happens at 3,801." The escalation allowance converted "prices might rise" into "four percent on fourteen million, drawn against documented index movement, refunded in full if unused." That conversion — unknown into a priced, triggered, written quantity — is the whole craft of contract negotiation.

What went wrong anyway. Meridian missed the August 1 deadline. The imaging vendor selected a different MRI unit after the GMP was set, requiring a deeper depressed slab, added structural framing, additional RF shielding, and a larger electrical feed. Pri gave a verbal go-ahead on a Thursday, and Kestrel's assistant superintendent let the concrete crew build it Monday — no written directive, no agreed price, no time-impact analysis, no T&M tickets for the first four days.

Notice what the protocol did and did not do. It did establish entitlement — nobody disputed that a post-GMP equipment change was a change to the contract. Meridian never argued the work was inside the guarantee, and that alone is worth the paragraph. What the protocol could not do was substitute for a written directive and daily tickets on the day the work started. Entitlement got Kestrel to the table. Documentation determined what it collected there — $142,750 against $186,400 spent.

The threshold concept, demonstrated. By final completion the contract sum was $49,594,200 — $2,094,200 and 4.4% above a number labeled guaranteed maximum price, on a well-run job with a competent owner, a written change protocol, and no bad faith on either side. The guarantee did exactly what it promised: it capped Kestrel's price for the scope defined in February of Year 1. Meridian's cost was never capped, and Pri knew it, which is why she carried roughly five percent of construction value as owner contingency and never had to go back to her board for emergency money.

Discussion questions

1. Meridian's counsel was analytically right that the honest time-related general-conditions rate was closer to $3,560/CD than $5,150/CD. Was accepting $5,150 in exchange for exclusive-remedy language a good trade for Meridian? What would have to be true about the project for it to be a bad one?

2. Kestrel refused to put the imaging suite inside the guarantee and offered a deadline instead of money. Suppose Meridian had insisted and Kestrel had priced the worst case at $340,000. Walk through what each party's position would have been when the vendor changed the unit. Who is better off, and does the answer depend on facts nobody knew in February?

3. The escalation allowance returns 100% to Meridian while the construction contingency returns only 75%. Explain the logic of treating those two reserves differently. Would you defend the same distinction if you were Kestrel's VP of Operations?

4. The August 1 equipment-selection deadline had no stated consequence beyond "it becomes a change." Draft — in plain English, two sentences — a consequence you would have added, and then argue the other side: why might Meridian have refused to accept it, and would Kestrel have walked?

5. Change order #14 settled at $142,750 against $186,400 of actual cost. Identify the three specific documentation failures that produced the $43,650 gap, and state which single one, fixed alone, would have recovered the most money.

Your turn

You are the project manager for a contractor setting a GMP on a $14,000,000 municipal library at 65% construction documents. The owner's attorney sends you three requests before the conversion meeting:

• Delete the differing site conditions clause; the contractor accepts all subsurface risk.
• Include a $600,000 allowance for "specialty millwork and shelving, design pending" inside the guarantee, with no reconciliation — the contractor absorbs any overrun.
• Set the extended general-conditions rate at $0/CD; time extensions only, no money.

Write a one-page response. For each request: state whether you accept, refuse, or counter; if you counter, give the specific mechanism — an allowance with a quantity and a unit price, a deadline and protocol, a threshold with sharing — and say what you are giving the owner in exchange. Then compute what you would add to your GMP if the owner refuses to move on all three, and show your arithmetic. The point of the exercise is that "no" is not an answer. A priced alternative is.
