Pay-If-Paid, Liquidated Damages, and a 45-Day Owner Delay

Pennsylvania distinguishes pay-when-paid clauses, which address timing, from pay-if-paid clauses, which make owner payment a condition precedent to the subcontractor's right to payment. Clear language-especially 'only if and when'-can create a condition precedent, shifting the risk of owner insolvency or nonpayment to the subcontractor. Because Keystone drafted the clause, ambiguity is construed against Keystone, but this language is fairly clear. The clause is not a penalty; it limits the source of payment rather than imposing a punishment. To rely on it, Keystone must prove that the owner has not paid specifically for Lehigh's drywall work and that the nonpayment is not due to Keystone's own breach, delay, or prevention. If Keystone's schedule revisions or defective work prevented the owner's payment, the condition is excused. The Pennsylvania Contractor and Subcontractor Payment Act imposes prompt-payment duties and interest, but it does not automatically void a clear pay-if-paid clause; the court should examine whether Keystone's own conduct caused the owner's nonpayment.

Pennsylvania enforces liquidated damages if, at contract formation, the amount is a reasonable forecast of anticipated harm and actual damages would be difficult to estimate. If the amount is grossly disproportionate to the probable loss, it is a penalty. $1,500 per day on a $480,000 subcontract is roughly 0.3% per day, which can be reasonable if tied to the owner's delay costs or extended overhead; it is not automatically a penalty. But Keystone must show that Lehigh caused the 10-day delay. The facts say Keystone's own schedule revisions shifted the work, so the delay may be concurrent or Keystone-caused. A liquidated-damages clause compensates for delay caused by the breaching party; it does not apply where the delay is not attributable to Lehigh. The court should allocate delay and deny the withholding if Keystone caused the shift.

Pennsylvania generally enforces no-damages-for-delay clauses, but recognizes exceptions: delays not contemplated by the contract, active interference by the owner or contractor, bad faith, and delays so unreasonable that they fall outside the parties' contemplation. Owner-directed design changes are often contemplated by a changes clause, so Lehigh may be limited to a change-order remedy rather than delay damages. But 45 days of changes that disrupted all trades, combined with Keystone's own schedule revisions, may qualify as active interference or an uncontemplated delay. The court should examine the subcontract's changes clause, whether Lehigh gave notice, and whether the delay was discrete and foreseeable. If the clause applies, Lehigh recovers nothing for the 45 days; if an exception applies, Lehigh may recover extended overhead proved with reasonable certainty.
