Pro forma contingency vs construction contingency is not a matter of naming. They are two funds, held by two parties, governed by two different documents, and the money in one is not available to the other. A budget that shows a single combined figure is describing a position you do not hold.
What you are actually holding
You have a pro forma with a contingency line, usually stated as a percentage of hard cost. You have a construction contract with a contingency inside the guaranteed maximum price. You may also have an owner contingency line in the project budget, sitting outside the contract.
On a summary page these three often collapse into one number, because a summary page is written to be readable rather than accurate. The combined figure looks reassuring. It is also the single most misleading line in a development budget.
The pro forma contingency was set early, before the design was finished, as a judgment about how much the whole project might move. It covers land, soft cost, financing, cost of construction and anything else the model touches.
The construction contingency was set late, by the contractor, against a defined scope of work, and covers a much narrower set of causes.
They overlap at one point only: both can be consumed by an increase in the cost of construction. Everywhere else they answer different questions, and neither can be spent by the party holding the other.
Pro forma contingency vs construction contingency, side by side
Who holds it. The pro forma contingency is a line in your model and, if you have carried it properly, cash or an equity commitment behind that line. The construction contingency sits inside the contract price and is held by the general contractor.
What it covers. The pro forma figure covers everything the model covers, which includes carrying cost during a delay, additional design fees, a leasing or absorption shortfall and cost of construction. The contract figure covers a narrow list written into the contract, usually the contractor own estimating misses, coordination between trades and minor scope development within the defined work.
Who approves a draw. You approve a draw against your line. The contractor draws against the contract line, and in many contracts does so without asking, reporting the movement afterwards in the monthly cost report.
What happens to the balance. Your unspent contingency is yours. Unspent contractor contingency is usually shared under the savings clause, at whatever split the contract sets, so it is not a fund that returns to you in full.
What it is measured against. Your figure is a percentage of total project cost. The contract figure is a percentage of the contract price, which is a smaller base. Three percent of one is not three percent of the other, and quoting both as percentages invites exactly that confusion.
Where the double count happens
The error is rarely deliberate. It happens because three documents are produced by three people and one page has to summarize them.
A common sequence. The pro forma carries 5 percent contingency on hard cost. The guaranteed maximum price arrives carrying 2 percent contractor contingency inside it. The budget is updated to show the contract price as the hard cost, and the 5 percent line is left in place. The summary now shows 7 percent of protection.
It does not exist. The 2 percent is inside a number you have already committed to pay, and it is spendable only by the contractor, on causes that mostly do not reach your side of the ledger. The protection available to you for a change you direct is 5 percent, not 7.
The same error appears in reverse when a sponsor deducts the contractor contingency from the contract price to make the number look competitive against a second bid. The bid without a visible contingency has one anyway, buried in the line items, and comparing the two as stated is comparing a disclosed figure with an undisclosed one.
The habit that prevents both errors is simple. Never let the two funds appear in the same column, and always write the controlling party in the row label. The mechanics of the contract side are set out in contractor contingency and owner contingency.
There is a third version of the error, and it is the expensive one. A sponsor reads the combined figure, decides the position is comfortable, and releases the owner contingency to cover a scope addition in month three. The addition is real and the decision looks reasonable against 7.7 percent of protection. Against 5 percent it would not have been made, or it would have been made smaller.
A number that is wrong on a summary page is an accounting problem. The same number is a decision problem the moment somebody spends against it, and that is usually well before anybody reconciles the two documents.
A worked example
Illustrative figures. Not taken from any client project and not a quotation.
Total project cost $95 million, of which construction is $71 million. The pro forma carries 5 percent contingency on construction cost, so $3.55 million. The guaranteed maximum price of $71 million includes a contractor contingency of $1.9 million, which is 2.7 percent.
The summary page shows contingency of $5.45 million, or 7.7 percent. The real figure available to the owner is $3.55 million.
Month seven: an owner directed change to the lobby finishes costs $640,000. That draws on the owner figure. Month nine: the contractor discovers a coordination miss between two trade packages costing $410,000. That draws on the contractor figure and does not touch yours.
Month fourteen: an allowance for exterior paving lands $520,000 above the figure carried. Allowance overages are owner cost in most contracts, so that draws on your figure as well.
By month fourteen the owner fund has absorbed $1.16 million against a starting $3.55 million, and the summary page still shows the contractor $1.9 million as though it were available. It is not, and $1.49 million of it has already been spent on causes that never reached your ledger.
What to do before you sign
- Put the pro forma contingency and the contract contingency on separate rows, with the controlling party written in each row label.
- State each as a dollar figure first and a percentage second, and say which base the percentage uses.
- Read the contract clause that says what the contractor contingency may be spent on, and write down what it excludes.
- Establish whether the contractor may draw without your approval, and whether you see the movement monthly or quarterly.
- Check the savings clause split, because that decides how much of any unspent balance comes back.
- List every allowance and ask which fund absorbs an overage, in writing, before signature.
- Model your own fund against a realistic change order volume rather than against a percentage rule of thumb.
If the answer to item three is that the clause does not say, that absence is the finding, and it is worth more than any percentage argument. The review packages describe how this reading is scoped and what it produces.
What we do
We read the contract contingency clause against your budget and tell you what is actually available to you, in dollars, on the day you sign. The output names the fund, the controlling party, the permitted causes and the realistic demands already visible in the allowance schedule and the procurement log. It is an adequacy question rather than a percentage question, and the readiness review is where it sits.
Questions people ask
Can I add the two contingency figures together in a budget summary?
You can, but the total describes protection you do not hold. The contract figure sits inside a price you have already committed to pay and can be spent only by the contractor, on causes written into the contract. A combined number overstates what is available to absorb a change you direct.
Is contractor contingency the same as profit?
No, although the savings clause blurs the line at closeout. It is a fund inside the price for defined causes, and in most contracts it is reported and reconciled rather than treated as earned. What happens to any unspent balance depends on the savings split, which is worth reading before signature rather than after.
How much owner contingency is enough?
A percentage is the wrong unit. The useful test is the demand already visible on the day you sign: the allowances likely to land above the figure carried, the unbought packages, the owner decisions still outstanding and the change volume typical for the delivery method. Size the fund against that list.
