A construction budget review an investor can do in an afternoon comes down to six lines. Not whether the total is right, which you cannot test from outside, but whether the total is settled, which you can.
What you are actually being shown
A sponsor sends a budget. It has hard cost, soft cost, financing cost, a contingency line and a total. Every line is a round number or a precise one, and the precision tells you nothing about the confidence.
You are not in a position to test whether the concrete is priced correctly, and pretending otherwise wastes the afternoon. Nobody outside the trade can, and the people inside it disagree with each other.
What you can test is something more useful: how much of the number is committed and how much is still a forecast. A budget where 80 percent of construction is under subcontract is a different object from one where 30 percent is, even when the totals are identical and both are labeled guaranteed.
That distinction is invisible on a budget page and visible in about forty minutes if you ask for the right four documents.
The second thing you can test is whether the protection is real. Contingency is the line investors read most and understand least, because it is usually presented as a single figure representing two funds with different owners.
The six lines in a construction budget review an investor should test
One. Committed against open. What share of the construction cost is under executed subcontract, and what share is priced from an estimate. Ask for it as a percentage and a dollar figure. This is the single best indicator of how settled the number is.
Two. The two contingencies, separately. Owner contingency, which the sponsor controls, and contractor contingency, which sits inside the contract price and does not. A budget showing one combined figure is overstating the protection available.
Three. Allowances, with the carried figure. Every allowance is a decision deferred with a placeholder attached. The total of allowances, and how many are carried against an outdated specification, tells you how much of the price is still a guess.
Four. Exclusions. The qualifications page of the construction contract. Everything on it is owner cost unless somebody proves otherwise, and none of it appears in the budget.
Five. Escalation. Whether an escalation assumption exists, what rate it uses and which trades it covers. An escalation allowance is not contingency and should not be counted as it.
Six. Interest reserve against the realistic date. Not the contract completion date. The date the schedule logic supports.
The four documents that answer all six
You do not need the whole data room. You need four things and none of them is confidential in a way that should cause an argument.
The procurement or buyout log. Package by package, awarded or estimated, with values. Answers line one directly.
The qualifications and assumptions page. Two to four pages at the back of the contract amendment. Answers line four and most of line three.
The allowance schedule. Answers line three and feeds line five.
The project schedule with its milestone dates. Answers line six, once you compare the contract date against the durations behind it.
If a sponsor cannot produce the first of those, that is the finding, and it is worth more than any analysis of the budget page. A buyout log either exists because somebody is managing procurement, or it does not, and the second case tells you the price is less settled than the word guaranteed suggests. What the word does and does not cover is set out in what a guaranteed maximum price actually guarantees.
What not to spend the afternoon on
Three things absorb investor attention and return very little.
Cost per square foot comparisons. Every building is a different building. A number that is high against a benchmark may reflect a difficult site, a better specification or an honest estimate, and a number that is low frequently reflects an incomplete one. The metric sorts nothing.
The contractor fee percentage. It is visible, it is easy to argue about, and it is usually between two and five percent of a number that can move by ten. The fee is the smallest lever on the page and the one most often pulled.
The design fee. Same problem, smaller number, and cutting it tends to produce exactly the incomplete documentation that drives change orders later.
The attention is better spent on the four documents above, because those describe how much of the price is still capable of moving. A settled price with an unremarkable fee is a better investment than an aggressive price with 60 percent of the work unbought, and only one of those two facts is visible on the budget page.
A worked example
Illustrative figures. Not taken from any client project and not a quotation.
Two budgets for comparable multifamily projects, both presented at $58 million of construction cost with 4 percent contingency.
Project A: buyout log shows 79 percent awarded. Allowances total $1.1 million across nine items. Qualifications page carries four exclusions, all with quantity caps. Owner contingency $2.3 million, contractor contingency $1.2 million, shown separately.
Project B: buyout log shows 37 percent awarded. Allowances total $4.6 million across twenty three items, six of them against a specification superseded in the last design issue. Qualifications page carries eleven exclusions, three with no cap. Contingency presented as a single $2.3 million figure that turns out to include the contractor fund.
Same headline number, same contingency percentage. Project B carries several million dollars more of open movement, and the owner controlled protection is roughly half what the page implies.
Neither budget is wrong. One of them is a price and the other is a forecast, and only the underlying documents say which is which.
The practical consequence is not that Project B is a worse investment. It may be the better one, on a better site, with a sponsor who simply funded earlier in the cycle. The consequence is that the two deals should be underwritten with different ranges, and presented to a committee with different ranges, and a process that reads only the budget page will give them the same one.
What to ask for before you fund
- The buyout log, package by package, with awarded and estimated values marked.
- The qualifications and assumptions page from the contract amendment.
- The allowance schedule with the carried figure and the design basis for each item.
- The two contingency funds shown separately, with the controlling party named.
- The escalation assumption, stated as a rate and a covered scope.
- The schedule with the critical path, and the interest reserve tested against it.
- Confirmation of who, independent of the sponsor and the contractor, has read all of the above.
Item seven is the one that changes the answer. A sponsor reading its own documents produces a sponsor conclusion, and a fund that relies on it has outsourced the diligence to the party being diligenced. The review packages set out what an independent reading covers and in what time.
What we do
We read the contract documents behind the budget and tell you what share of the number is committed, what is still open and what the open part could reasonably become. The output is a register with a dollar range on each line and a page reference behind it, written for somebody who will never visit the site. We do not price work and we do not produce a competing estimate. The reading is the cost and change exposure assessment.
Questions people ask
Can I tell whether a construction budget is accurate from outside?
Not in the sense of testing whether each trade is priced correctly, and any process that claims to is overselling. What you can establish is how settled the number is: how much is under subcontract, how much sits in allowances, and what the qualifications page leaves as owner cost. Those three are measurable.
What percentage of buyout should I expect at closing?
It varies by delivery method and market, so the useful move is to ask for the figure rather than to hold a threshold. What matters is that the number is disclosed and tracked, because an undisclosed buyout position is the most common way an apparently firm price turns out to be an estimate.
Is contingency of four percent enough?
The percentage answers nothing on its own. Size the fund against the demands already visible: allowances likely to land high, uncapped exclusions, unbought packages and outstanding owner decisions. Four percent against a clean document set is generous. The same four percent against twenty three allowances is thin.
