Case Study 25.2 — The Autopsy: Reconstructing CO #14 Eight Weeks Late
All people, companies, and projects in this book are illustrative composites. The numbers are internally consistent and typical of the situation described; they are not drawn from a specific real project.
Setup
Project: Northgate Outpatient Pavilion — CM at Risk, $47,500,000 GMP, Meridian Health System owner.
The change: Meridian's imaging vendor selected a different MRI unit after the GMP was set. The new unit required a deeper depressed slab, additional structural framing, more RF shielding, and a larger electrical feed.
How it started: Pri Sethi, Meridian's owner's representative, gave a verbal go-ahead on a Thursday. Kestrel's assistant superintendent — under schedule pressure, wanting to help, and genuinely trying to keep a concrete crew productive — let the crew build it Monday.
What did not exist when the work started: a written directive. An agreed price. A time-impact analysis. And time-and-material tickets for the first four days.
The people in this case study are not the ones who built it. They are the two people who had to reconstruct it: Lorena Vasquez, project accountant, and Dani Okonkwo, field engineer. Eight weeks after the pour, Ray handed them a folder and three days.
What Happens
Week 8 — the assignment
"Meridian's controller wants a substantiated number," Ray said. "Pri's not fighting us. She knows it happened. But she has to take a number to a board, and the number has to have paper under it. Whatever we can prove, that's the number we ask for."
Lorena had already run the job-cost report. The cost side was not ambiguous at all.
Actual cost incurred on the imaging-suite change: $186,400.
Pri's recollection of the conversation on the Thursday was that it would run "about $60,000." She was not lying and she was not stupid. She had been told a slab would get deeper. Nobody had told her about the framing, the shielding, the feed upsize, or the eleven days of self-perform labor, because on the Thursday nobody knew.
"So it's a hundred and eighty-six four," Dani said. "We show them the cost report."
Lorena, who has done this before: "A job-cost report is not substantiation. It is an assertion by us about our own books. Every line of it has to be traceable to a document that a third party would recognize. Let's find out what we have."
Days 1 through 3 — the reconstruction
They worked through it line by line. Here is the result, and it is the most important table in this chapter.
| # | Cost element | Actual | Substantiated | Gap | What existed | What did not |
|---|---|---|---|---|---|---|
| 1 | Concrete material — additional 62 CY, 4,000 psi, plus pump time | 14,900 | 14,900 | 0 | Batch tickets, supplier invoices, delivery tickets signed in the field | — |
| 2 | Reinforcing steel and embeds | 19,600 | 19,600 | 0 | Fabricator invoice, delivery tickets, revised placing drawing | — |
| 3 | RF shielding — Shieldcore Systems | 44,800 | 44,800 | 0 | Written subcontract change order, executed before the work | — |
| 4 | Electrical feed upsize — Halcyon Electric | 26,300 | 12,800 | 13,500 | Material invoices; labor tickets from day 5 onward | Halcyon's T&M tickets days 1–4; no countersigned daily authorization |
| 5 | Structural framing additions — Ironbridge Steel | 16,200 | 6,400 | 9,800 | Shop ticket for the added members | No written directive; the verbal scope was never confirmed in writing |
| 6 | Kestrel self-perform concrete labor, days 1–4 | 27,400 | 4,200 | 23,200 | Daily report headcounts only — bodies on site, no task coding | Signed T&M tickets with named workers, hours, and task |
| 7 | Kestrel self-perform concrete labor, days 5–11 | 13,700 | 11,700 | 2,000 | T&M tickets started day 5 | Clean cost coding on two days |
| 8 | Formwork, shoring, and pump rental extension | 8,900 | 2,300 | 6,600 | One rental invoice | Extension not tied to the change; no separate cost code |
| 9 | Equipment and crane hours redirected to the pour | 5,600 | 0 | 5,600 | — | Equipment logs never coded to the change |
| 10 | Rework — two embedded conduits relocated after the pour | 4,700 | 0 | 4,700 | — | No NCR, no field directive, no photographs |
| 11 | Additional testing and special inspection | 4,300 | 4,300 | 0 | Testing laboratory reports and invoices | — |
| TOTAL | 186,400 | 121,000 | 65,400 |
Dani found the pattern on the afternoon of day two and said it out loud in a way that made Lorena put her pen down.
"Every row we can prove is a row where somebody else's paperwork proves it."
That is exactly right, and it is the single most transferable observation in this case study. Rows 1, 2, 3, and 11 have zero gaps. In every one of them, a third party generated a document as part of its own routine business process — a ready-mix plant prints a batch ticket whether Kestrel wants one or not; a fabricator invoices; a testing lab reports; a subcontractor's own change order gets executed because subcontractors do not do extra work for free.
Rows 4, 5, 6, 8, 9, and 10 have all the gaps. In every one of them, the record had to be created deliberately by a Kestrel employee, in the moment, under pressure, before anyone knew it would matter.
That is not a story about carelessness. It is a story about system design. Documentation that depends on people remembering to document under pressure will fail under pressure, which is exactly when you need it.
Day 3 — what they tried and could not do
They did not give up on the $65,400. They tried four reconstructions, and it is worth knowing why each failed, because you will try all four someday.
Reconstruction attempt 1 — the daily reports (row 6). The daily reports existed and were complete in the sense that they recorded a headcount: nine concrete workers, on site, 7:00 a.m. to 3:30 p.m. What they did not record was which of the nine were on the imaging depression and which were on the adjacent slab-on-grade pour that was proceeding in the same week. Dani could establish that nine people were on site for four days. They could not establish that any specific person spent any specific hour on the change.
Meridian's controller accepted four workers for four days as a floor — the smallest crew that could have plausibly performed the work — and would not go higher without a document. That is where $4,200 of $27,400 came from.
Reconstruction attempt 2 — the crew foreman's memory. Jamal Foster's foreman remembered it well and described it credibly. He also described it eight weeks later, to his own employer, in a conversation about money his employer wanted. Lorena took the statement and put it in the file, and it was worth something in the negotiation and nothing at all as substantiation. A statement made after the dispute, by a party with an interest, in support of that interest, is argument. It is not evidence. This is not cynicism about Jamal's foreman, who was honest. It is how records are weighed by everyone who weighs records.
Reconstruction attempt 3 — the photographs (row 10). Somebody had to have photographed the conduit rework. Two thousand photographs existed from that month. Dani went through all of them. There were seventeen of the imaging area that week. None of them showed the two conduits before relocation, because nobody photographs a conduit that is in the right place, and by the time it was in the wrong place, the crew fixed it in about four hours and moved on.
That row — $4,700 of real, incurred, unrecoverable cost — failed on six photographs and a paragraph that nobody took ninety seconds to produce.
Reconstruction attempt 4 — the equipment logs (row 9). The logs existed. Every piece of equipment on the job was logged daily with hours. But the hours were coded to the area, not to the change, and the imaging suite area code covered both the change work and the base-contract work happening in the same footprint. There was no defensible way to split it, and Lorena would not invent one.
"We could allocate it," Dani said. "Pro rata."
"We could," Lorena said. "And then the first question in the meeting is 'how did you arrive at that,' and the answer is 'we estimated it,' and now every other number in the package is an estimate too. You never spend a good number to defend a bad one."
They submitted $121,000.
Week 16 — the negotiation
The meeting took ninety minutes. Pri Sethi did not dispute that the work had been performed, did not dispute that she had authorized it, and did not dispute a single one of the four fully documented rows — those were accepted in about six minutes with no discussion, which is what full documentation buys you.
The argument was entirely about the $65,400.
Pri's position was not hostile and it was not unreasonable. It was this: I believe you. I cannot take "we believe them" to a board that has already been told this change would cost sixty thousand dollars. Give me something a controller can sign.
They settled at $142,750.
| Line | Amount |
|---|---|
| Kestrel's actual cost | $186,400 |
| Substantiated with contemporaneous records | $121,000 |
| Negotiated settlement | $142,750 |
| Premium paid above substantiation | $21,750 |
| Kestrel's unrecovered cost | $43,650 |
| Time impact claimed | 9 CD |
| Time impact granted | 4 CD |
Meridian paid $21,750 above what Kestrel could prove. That premium was real, and it came from the relationship, from eleven months of remaining project, and from the fact that Pri's own verbal go-ahead had started the whole thing. Roughly 33 cents of every undocumented dollar came back. Sixty-seven cents did not.
The time claim went the same way and for the same reason: Kestrel claimed nine calendar days of impact and was granted four, because four could be traced to a delayed follow-on activity in the schedule update and five rested on a narrative about disruption that no contemporaneous record supported.
Analysis
What each missing record was worth
Apply the 67 percent shortfall to the gaps and the arithmetic becomes uncomfortable.
| Missing record | Gap | Realized loss (≈67%) | Time it would have taken |
|---|---|---|---|
| T&M tickets, self-perform concrete, days 1–4 | $23,200 | ≈ $15,480 | ~10 min/day × 4 days = 40 minutes |
| Halcyon T&M tickets countersigned, days 1–4 | $13,500 | ≈ $9,010 | ~5 min/day | |
| Written directive to Ironbridge confirming the added framing | $9,800 | ≈ $6,540 | one email, ~4 minutes | |
| Rental extension coded to the change | $6,600 | ≈ $4,400 | one cost-code entry | |
| Equipment logs coded to the change | $5,600 | ≈ $3,740 | one line per day on a form that already existed | |
| NCR and photographs of the conduit rework | $4,700 | ≈ $3,140 | six photographs and a paragraph | |
| Two miscoded labor days | $2,000 | ≈ $1,330 | correct coding at entry | |
| Total | $65,400 | ≈ $43,650 | under two hours |
Forty minutes of time-and-material tickets was worth $15,480 — about $387 per minute.
Set the $43,650 against Kestrel's entire CM fee on Northgate, $1,804,800. One documentation failure on one change order consumed 2.4 percent of the fee on a $47.5 million project, on work that everyone agreed had been performed and that the owner's representative had genuinely authorized.
Why this is the threshold concept
A record created on the day, by someone with no idea it would ever matter, is evidence. The same facts assembled eight weeks later by someone who very much wants them to matter is argument — and argument loses.
Everything in this case study is one demonstration of that sentence. The batch ticket is evidence because a ready-mix plant printed it as a matter of routine and had no stake in the dispute. The foreman's recollection is argument because it was produced by an interested party after the fact. Both describe the same reality. Only one of them gets paid.
Notice what did not fail. Kestrel was right. The work was real, it was authorized, it was necessary, and Meridian benefited from it. Being right was worth $121,000 out of $186,400.
The three contract mechanisms that existed and were not used
None of this required heroics. Three ordinary instruments were sitting in the contract:
- Written notice of a change, within the contractually specified period, before or immediately upon starting the work.
- A construction change directive — the instrument that exists precisely for the situation where an owner needs work to proceed before price and time are agreed. A CCD would have obligated Kestrel to proceed and fixed the cost-accounting basis from hour one.
- The contract's force-account provisions, which typically state what records must be kept for directed work performed on a time-and-material basis, and frequently require the owner's representative to countersign the daily tickets.
Notice periods, authorized instruments, and force-account record requirements vary substantially by contract form and by jurisdiction, and are frequently stricter on public work. Read yours before you need it.
And note the trap that caught everyone. Pri Sethi was the owner's representative. Whether her verbal go-ahead constituted authority to direct a change depends entirely on what the contract says about how changes are directed — and on most standard forms, a verbal instruction from an owner's representative is not that.
What Kestrel changed
Four things, and they cost essentially nothing to operate.
- A change-file rule. The moment any potentially changed work is identified, a change file is opened and a cost code is issued — before anyone decides whether it is a change. The cost of opening a file on something that turns out not to be a change is five minutes. The cost of not opening one is on the table above.
- T&M tickets from hour one, countersigned daily. Not at the end of the week. Not at the end of the change. Daily, with named workers, hours, and task, presented to the owner's representative for signature — and if they decline to sign, the ticket is transmitted anyway with a note recording that it was presented and declined. A declined ticket that was contemporaneously transmitted is worth vastly more than no ticket.
- No self-perform work on a change without a directive, and no verbal go-ahead accepted without a same-day confirming email: "Confirming our conversation this morning: you have directed Kestrel to proceed with the deepened slab at the imaging suite. We are proceeding on a time-and-material basis effective today and will submit daily tickets. Pricing to follow." That email takes four minutes, requires no authority, and would have converted rows 5 and 9 from gaps into substantiation.
- Photographs before, during, and after any change or rework, tagged to the change number. Nobody photographs a conduit that is in the right place. That is exactly why the standing rule has to be photograph the change, not photograph what looks important.
Discussion Questions
-
Lorena refused to allocate the equipment hours pro rata, saying "you never spend a good number to defend a bad one." Argue the other side: under what circumstances would a defensible, clearly labeled estimate be better than claiming zero? What would you have to disclose for it to be honest?
-
Rows 1, 2, 3, and 11 had zero gaps because a third party generated the record as a matter of routine. Identify three other categories of construction cost where a third party's routine paperwork will substantiate you automatically — and three where nothing will exist unless you create it. What does that tell you about where to aim your documentation effort?
-
Meridian paid $21,750 above the substantiated amount. Describe three specific circumstances under which that premium would have been zero — and explain why the premium is largest at exactly the time in a project when disputes are least likely.
-
Kestrel's assistant superintendent let the crew build it on Monday because he was trying to help. He was not reckless and the work genuinely needed to start. Design a rule for your own project that would have stopped him without also making your organization slow and bureaucratic about every field decision. Then stress-test it: what does your rule do at 6:30 a.m. on a Saturday with a pump truck on site?
-
Kestrel claimed nine calendar days and was granted four. The five denied days were not fictional. Explain what record, created contemporaneously, would have converted the disruption narrative into a provable time impact — and say which chapter of this book covers building it.
Your Turn
Take a change on your own project — or invent one on the Willow Street Community Center: the City's parks director asks, verbally, on a Thursday, for the gymnasium storage room to be reconfigured with an added partition and a relocated door, and the framing crew is in that area next week.
Write the four documents you would create before the crew touches anything, in full:
- The same-day confirming email to the owner's representative.
- The written notice of a change in the form your contract requires (check the notice period).
- A blank daily T&M ticket for this work, with the fields filled in that you can fill in today — including a line for the owner's representative's signature.
- The change-file cover sheet: change number, cost code, description, who directed it, when, in what form, and what records will be kept.
Then answer one question honestly: how long did that take you? Compare it to $43,650.
