Building construction contingencies that survive lender scrutiny

A contingency should explain how the project will pay for uncertainty that remains after diligence and contracting. A single percentage of hard costs can be a useful summary, but it is a weak explanation of whether a large apartment development has enough money to finish. The borrower should be able to identify the risks covered, the evidence supporting the amounts, and the approvals needed to use the funds.

The OCC's commercial real estate handbook connects construction feasibility with cost review and monitoring of remaining funds.^[1] Freddie Mac's construction-report requirements similarly call for review of projected costs, contingencies, reserves, and the schedule in the executions covered by that chapter.^[2] These sources support a risk-based budget review; neither establishes one universally sufficient private-loan contingency percentage.

Separate known costs from unknown outcomes

Begin by identifying incomplete scope. If a retaining wall is known to be necessary but has no price, it belongs in the base budget as a reasoned allowance. If unforeseen subsurface conditions could require a larger wall, the additional exposure is a contingency risk. Combining the two conceals whether the base scope is fully funded.

Make the distinction visible in the estimate. For each allowance, state the quantity, assumed unit price, design status, and date of the estimate. For each contingency risk, state the event, possible cost, likely timing, mitigation, and responsible party. This is an analytical method for the owner and lender to review together, rather than a formal requirement that every lender uses the same schedule.

Do not count the contractor's contingency automatically as money freely available to the owner. Its use and any savings treatment come from the construction contract. Likewise, a guaranteed maximum price needs a scope and exclusions analysis: an agreed price for defined work does not describe how every omitted or changed item is paid. Read the contract before assuming a risk has transferred.

Independent review is particularly useful where the development combines different disciplines. Freddie Mac's chapter 63 calls for an architectural consultant's analysis of design completeness, costs, environmental information, geotechnical recommendations, and other delivery factors.^[2] The useful output is a list of unresolved items and their budget consequences, not simply a conclusion that the total estimate looks plausible.

Carry schedule risk into the financing budget

Hard-cost contingency does not automatically cover the financial consequences of delayed completion. A delay can add contractor general conditions, insurance, interest, taxes, security, and operating deficits. Model those expenses using the projected balance and operating schedule. A percentage based on building costs alone can miss most of this exposure.

The OCC's interest-reserve discussion explains why reserve adequacy depends on the pace of loan advances, rates, and project delays.^[1] A reserve that looks generous at closing can become inadequate after a faster draw schedule or a later opening. Keep interest reserve sensitivity separate from physical construction contingency so each can be tested against its actual driver.

For an original example, assume a $180 million development has $110 million of building and site costs, a $5.5 million owner contingency, and a $9 million interest budget. Assume that the entire interest budget is needed for the original schedule. The owner contingency equals 5% of those hard costs, but that percentage alone says nothing about its sufficiency. Assume the risk review identifies $1.4 million of uncertain excavation exposure, $1.1 million of incomplete utility pricing, and $1.3 million of potential design coordination changes.

If all three cost events occur, they use $3.8 million and leave $1.7 million of the owner contingency. Now assume a six-month delay, an average $100 million outstanding loan balance, and an annual simple interest rate of 7.5%. Additional interest is $3.75 million. Add assumed extended general conditions of $1.2 million and taxes, insurance, and security of $450,000; the delay adds $5.4 million before operating effects.

The project could have adequate contingency for the specified physical events while lacking enough money for the delay. Conversely, a large interest reserve would not solve the excavation invoice if the documents prohibit reallocating it. The budget must show both the amount and permitted use of each reserve.

Account for connected risks

Avoid summing only the most likely cost for each item when several items can deteriorate together. A utility delay may prevent commissioning, which delays occupancy and extends interest. A design change may require new permits and procurement. These are connected events, not three independent small variances.

Create at least one combined downside case around a coherent sequence. In the example, the owner might model delayed utility completion together with extended site work, later unit delivery, and six more months of debt carry. Then identify which contractual party bears each expense. The owner needs funding only for risks it retains, but should verify that a counterparty expected to bear a risk has the capacity and obligation to perform.

Also consider what information is still unavailable. A geotechnical report with limited borings, an unresolved design detail, or an unconfirmed utility quote leaves a different risk profile from completed diligence and binding pricing. Contingency should decline when uncertainty is genuinely resolved, not merely because management needs a smaller budget to support the financing request.

Understand the lender's balance test

A cost overrun can affect draws before contingency is exhausted. A construction agreement may test whether remaining committed funds are sufficient for the estimated cost to complete. An older SEC-filed form illustrates that mechanism and requires a response to a projected shortfall under its own terms.^[3] Each new loan has its own calculation, permitted sources, and remedies.

Ask whether the remaining-funds calculation includes undisbursed equity, loan availability, interest reserves, retained contractor amounts, approved savings, and committed public reimbursements. Then ask who estimates remaining cost. If the lender's inspector uses a higher amount than the sponsor, the contractual test may become binding even while the sponsor's internal model still balances.

The same filed form restricts budget amendments and change orders.^[3] The borrower should therefore establish a usable procedure for reallocating verified savings and approving necessary work. Budget discipline is valuable; an approval process that cannot operate on the construction schedule can create avoidable delays and additional expense.

Use contingency as a monitored resource

Maintain a monthly contingency reconciliation. Show beginning availability, approved uses, pending requests, forecast unresolved exposure, and remaining availability. Do not show the entire unused balance as free surplus when known claims or likely changes have not yet been approved. A pending invoice consumes economic capacity even if it has not entered the lender's draw ledger.

Tie that reconciliation to a forecast at completion. Record why the forecast changed and what evidence supports the remaining amount. A lender inspection should complement the owner's control process. The SEC-filed form expressly limits reliance on lender inspections, illustrating that a lender's review need not transfer the owner's project responsibility.^[3]

If the downside case exceeds available funding, act while the sponsor still has choices: revise scope, complete additional diligence, negotiate risk allocation, contribute more committed capital, or reduce borrowing. Do not assume a later lender accommodation will replenish the budget. The OCC's July 2026 loan portfolio handbook describes prudent workouts as plans that address problem assets rather than simply postpone losses.^[4] A request for new money will need its own support.

The strongest contingency presentation has a clear base scope, explicit remaining uncertainties, a combined delay case, and a documented route for using the money. It gives the sponsor a practical decision tool during construction and gives the lender an explanation it can test. A percentage can summarize that work, but it should follow the analysis rather than substitute for it.
