Construction Disputes: Substantial Completion and Liquidated Damages in the Philippines

The Supreme Court's decision in Transcept Construction and Management Professionals, Inc. v. Aguilar (G.R. No. 177556, December 8, 2010) clarifies a critical question in Philippine construction law: when does a contractor's partial performance count as "substantial completion," and how does that affect a property owner's right to liquidated damages? The ruling offers practical guidance for both contractors and project owners navigating construction disputes.

The Facts of the Case

Teresa Aguilar hired Transcept Construction to build a vacation house in Batangas under a contract worth P3,486,878.64, with completion set for June 7, 2005. After Aguilar questioned a billing that she found excessive, Transcept stopped work in February 2005. Testing later revealed substandard workmanship and materials.

The parties then signed a second contract in May 2005, extending the completion date to July 29, 2005, and reducing the contract price to P1,632,436.29—the amount of Aguilar's downpayment. Transcept still failed to finish on time, claiming delays from "additional works" Aguilar allegedly ordered. Aguilar filed a complaint with the Construction Industry Arbitration Commission (CIAC).

The Dispute Over Completion Percentage

The CIAC assessed Transcept's actual accomplishment at P1,602,359.97, or 98.16% of the contract price. Because this exceeded 95%, the CIAC ruled that the project was "substantially completed," and denied Aguilar's claim for liquidated damages.

The Court of Appeals disagreed. It recomputed the indirect costs and arrived at only 87.81% completion, awarding Aguilar liquidated damages of P163,243.63. The Supreme Court, however, reinstated the CIAC's computation, noting that Aguilar had not presented evidence to dispute Transcept's figures on general requirements—costs for mobilization, overhead, insurance, and similar items that are incurred at the start of a project regardless of contract amount.

The Rule on Substantial Completion

The Court applied Section 20.11(A)(a) of CIAP Document No. 102, which states that substantial completion occurs when the contractor completes 95% of the work, provided the remaining work does not prevent the normal use of the completed portion.

Since Transcept's accomplishment reached 98.16%, the Court found substantial completion. It then applied Article 1234 of the Civil Code: if an obligation has been substantially performed in good faith, the obligor may recover as though there had been strict and complete fulfillment, less damages suffered by the obligee. Accordingly, Aguilar was entitled only to P30,076.72—the value of the unaccomplished works—not liquidated damages.

Additional Works and Consultancy Fees

The Court also addressed Transcept's claim for P189,909.91 for "additional works." The Court rejected this claim, finding that the so-called additional works—such as lifting roof beams because the construction was three meters short of specifications—were merely corrections of substandard work under the first contract. The second contract was entered into precisely to fix these defects, so Aguilar should not pay for their correction.

The Court did, however, uphold the award of P135,000 for consultancy services, which included payments to both the testing laboratory and the engineer who evaluated the contractor's performance.

Practical Takeaways

• The 95% threshold matters. Under CIAP Document No. 102, completing 95% of the work may constitute substantial completion, barring claims for liquidated damages even if the project is late.
• Substantial completion still requires payment for deficiencies. A contractor who substantially completes a project must still pay the owner the value of whatever work remains unfinished.
• Document your evidence. In this case, the owner's failure to present evidence on indirect costs weakened her position. Both parties should preserve records and challenge adverse computations early in the proceedings.
• Corrections of defective work are not "additional works." A contractor cannot charge extra for fixing its own substandard performance, especially when a new contract was signed precisely to remedy those defects.
• Liquidated damages are not automatic. Even when a project is delayed, liquidated damages may be unavailable if the work reaches substantial completion.
