Case Study 1 — Twenty-Eight Openings: The Mockup That Was Never a Standard

All people, companies, and projects in this book are illustrative composites. Northgate, Kestrel Construction Group, Meridian Health System, Halvorsen + Pike, and Vantage Glass & Glazing are not real entities, and the dollar figures are constructed to teach the arithmetic honestly.

Setup

The project. The Northgate Outpatient Pavilion — 132,000 gross square feet, four stories, Meridian Health System, delivered by Kestrel Construction Group under a CM-at-Risk agreement with a Guaranteed Maximum Price (GMP) of $47,500,000 and a 565-calendar-day contract time. Notice to proceed March 3, Year 1. Substantial completion September 18, Year 2.

The scope. Interior aluminum-framed storefront — the glazed partitions separating clinic corridors from sub-waiting areas and consult rooms. Roughly 240 openings across the building; 28 of them on level two, in the north clinic corridor. Installed by Vantage Glass & Glazing, whose project manager is Renée Duplessis and whose lead glazing foreman is Art Sowinski.

The people.

The constraint. Month fourteen. The building has been dried in since March 28, Year 2. MEP rough-in has a May 30 milestone. Level two is in interior finishes, and the level-two finish path has eleven calendar days of float in the current schedule update. Substantial completion is four months out.

The setup that mattered, and that nobody was watching. In month nine, Vantage built a mockup of a single interior storefront opening in the level-one shell. Dale Whitcomb reviewed and approved it. The approval form was signed, the mockup was photographed, the photographs went into the submittal file, and the mockup was left standing in the corner of the shell. Six people attended the review: Dale, Renée, Pri, Dani, Ray, and the storefront manufacturer's representative.

Art Sowinski was not one of them. He was finishing a job across town. Nobody excluded him; nobody thought of him.

What Happens

May 4, Year 2 — the four seconds

Dale Whitcomb, Ray, and Dani are on a routine Thursday walk of level two. Dale stops at opening 2-102 and looks at the head of the frame.

Dale: "This isn't the mockup."

Ray: "It's the approved shop drawing."

Dale: "Ray. It isn't the mockup."

The difference, measured:

Twenty-eight openings in a 190-foot corridor, each one stepping the horizontal sightline three-quarters of an inch off the door head datum. Level three's 34 openings are staged on the floor and not yet installed.

May 4 — the two questions that decided the outcome

Ray goes downstairs to look at the mockup. It is still standing. Eleven sheets of gypsum board lean against it. There is a coffee cup on the sill. Nobody has touched it since month nine.

Then he finds Art Sowinski on level three.

Ray: "Art. Have you seen the mockup?"

Art: "What mockup?"

Two questions, four seconds each, and the case is essentially decided. The mockup was built, reviewed, approved, and filed. It became a document. It never became a standard, because the crew who installed 240 openings never stood in front of it.

Then the second finding, which complicated everything. Dani pulls Vantage's approved shop drawings and walks the corridor opening by opening. On 17 of 28 openings the installed condition matches Vantage's approved shop drawing sheet 4 — which itself does not match the mockup. On the other 11, the installed condition matches neither: Art's crew had worked from a field sketch a Vantage detailer emailed them, which differed from their own approved shop drawing.

So three documents were in play, and no two of them agreed.

May 4–6 — stop, bound, document

Kestrel's immediate actions, inside twenty-four hours:

1. Level-three storefront installation stopped.
2. Level-two openings tagged; Summit Interior Systems' gypsum returns and painting at those 28 openings held.
3. All 28 openings measured and photographed with a tape in frame.
4. Levels one and four inspected to bound the extent — level one storefront (19 openings) not yet installed; level four (31 openings) not yet installed. The exposure is 28 openings, not 240. That fact alone is worth roughly $700,000, and it is the direct result of Dale looking up in month fourteen rather than month eighteen.
5. NCR-023 issued to Vantage, copied to H+P, Pri Sethi, and the storefront manufacturer.

May 7 — the four dispositions, on the table

Kestrel, Vantage, and H+P sat down and worked all four dispositions rather than arguing about the first one anybody proposed. This is the part worth copying.

Note what disposition 3 turned on. Not "does it perform" — it performs identically. It turned on whether the deviation is visible and permanent, and on the owner's judgment of the value of what they had bought. That is exactly the boundary the specification's "satisfaction of the Architect" language draws, and it is why that phrase can only be settled with a physical benchmark.

May 8 – May 28 — the rework, priced

Schedule impact: six calendar days of the level-two finish sequence, consuming six of the eleven available days of float on that path. Level-three storefront was held nine working days awaiting the revised shop drawing and the re-fabricated heads. Substantial completion on September 18, Year 2 was not affected — which is the only reason this story is a case study and not a claim.

June — the negotiation over who pays

Three parties, three defensible positions, and the truth in the middle.

Renée Duplessis (Vantage): "Seventeen of those twenty-eight match a shop drawing your office forwarded and the architect stamped. You reviewed it, Dale reviewed it, nobody said a word about the mockup. I'm not paying for a review failure."

Dale Whitcomb (H+P): "The specification makes the approved mockup the standard for the work. We reviewed the shop drawing for general conformance with design intent; we did not catch a three-quarter-inch head dimension, and I'll own that we should have. But the standard didn't change because we missed it."

Ray: "Eleven of the twenty-eight don't match anybody's document. Your crew built those from a field sketch."

Renée: "Which our detailer sent because your field engineer asked a question at the wall. That's a Kestrel question producing a Vantage sketch on a Kestrel project."

Margo Deacon: "Can I say the thing nobody's saying? We built a mockup nine months ago, put a coffee cup on it, and never showed it to the man who installed two hundred and forty openings. That's not Vantage. That's us."

Margo was right, and Nadia Haddad — who had to decide whether Kestrel fought this or funded it — took about ninety seconds to agree.

The settlement:

One detail that matters and that young project managers routinely get wrong: Kestrel's $46,300 could not be charged to the GMP construction contingency. Most GMP agreements exclude the cost of correcting defective or nonconforming work from the cost of the work. It came out of the CM fee of $1,804,800 — a 2.6% reduction in the fee on a $47.5M job, produced by a meeting nobody scheduled.

Analysis

What actually failed

Not the installation. Art Sowinski's crew installed 28 openings plumb, square, and tight, with the correct glass and the correct hardware, to a detail somebody had given them. Their workmanship was fine. The system failed to deliver them the right standard.

There are four separate breaks in that chain, and every one of them is a handoff, not a technique. Nobody in this story lacked skill. Information failed to move between people. That is theme 6 — you build with people, not with materials — and it is why quality management is mostly a communication discipline wearing a technical costume.

The economics, plainly

The $1,630 was never a decision. Nobody weighed it and declined. It simply was not on anybody's schedule, because pre-installation conferences live in a specification section Kestrel's field staff had not read. That is the most common way money is lost in construction: not by a bad decision, but by a decision that was never presented to anybody.

The three system changes Kestrel made

The NCR's corrective-action field is the only part of this story that made money back. Kestrel made exactly three changes, and used them on every job afterward.

1. Benchmark installation required for every appearance-critical scope. A formal benchmark approval form was added to the quality plan. The first production installation of any appearance-critical scope stops for inspection by Kestrel QC, the architect, and the subcontractor's foreman, against the approved mockup, before the second one goes in. The installing crew must be present. A companion rule: any crew change on a benchmarked scope re-triggers the benchmark walk. Marginal cost per scope: about three to five hours.

2. Pre-installation conferences became scheduled activities. Wei Chen pulled every specification-required pre-installation conference into the schedule as a real activity with a real predecessor — approved submittal — and a real successor: the first installation. They appear on the four-week look-ahead. Margo runs them. They take 45 minutes. On the next project, 31 of 34 happened; on Northgate before this event, 6 of 34 had.

3. One new column in the submittal log: "Issued to installer — date / signed by." No scope starts until that cell is filled with a foreman's signature. The approved submittal gets printed, hand-delivered to the person who will install the work, signed for, and posted at the work face. Cost: a column in a spreadsheet and about ten minutes per submittal.

Those three changes cost Kestrel, generously estimated, under $30,000 a year in staff time across a $410M revenue business. The first one alone would have paid for a decade of them in a single corridor.

The part I want you to sit with

I have told this story to five classes of project engineers, and every single time somebody asks the same question: "Wasn't it just a shadow line? Wasn't Dale being precious?"

No. And here is the test that settles it. Meridian bought a building that would have one continuous head datum down a 190-foot clinical corridor, because that is what the approved mockup showed and what the specification made the standard. If Kestrel delivers something else and no one says anything, Kestrel has quietly substituted its own judgment for the owner's purchase. Do that ten times on a job and you have delivered a different building than the one you sold — a little cheaper, a little less careful, and entirely without anybody's consent.

The three-quarters of an inch is not the point. Whether the standard is the standard is the point.

Discussion Questions

1. Vantage's argument — "seventeen of these match a shop drawing your office forwarded and the architect stamped" — is genuinely strong. Why did it not carry the day, and what would have had to be different for it to succeed? Consider what an approved submittal does and does not do to the contract requirements.

2. Disposition 3 (use as is) was rejected because the deviation was visible and permanent. Construct the strongest case for accepting it with a credit. What credit amount would you have proposed, on what basis, and what would you have asked for besides money?

3. The extent was bounded at 28 openings because three of the four floors had not yet been installed. Suppose instead that Dale had found this at the architect's punch in month eighteen, with all 240 openings installed. Re-price the event and describe how the negotiation would have changed — not just the number, but the positions each party would have taken.

4. Kestrel's $46,300 came out of fee rather than the GMP construction contingency, because correcting nonconforming work is typically excluded from the cost of the work. Would you have argued that the head-of-wall rework at the nine rated openings ($4,680) is different in character from the rest? On what basis?

5. Of the three system changes, which one has the highest return per dollar of effort, and which is most likely to decay back to nothing within a year? What would you do to keep the fragile one alive?

Your Turn

You are Dani Okonkwo on May 5, the day after the discovery. Ray has asked you for a one-page memo before the disposition meeting.

Produce:

• A bounding statement. Exactly which openings are affected, on which levels, with which of the three documents each one matches. Present it as a table with a total.
• A hold recommendation. What work do you recommend stopping, for how long, and what does each day of that hold cost? Use $5,150 per calendar day for extended general conditions and state clearly whether you believe this path is critical.
• Three questions for the disposition meeting that you believe nobody else will ask.

Then, separately, write the corrective action field of NCR-023 in no more than 80 words — the system change, not the repair. If your text contains the phrase "reminded the crew," delete it and start over.
