Construction Defects Contractors Liability and Owners Rights Under Philippine Law

The Supreme Court's ruling in Financial Building Corporation v. Rudlin International Corporation (G.R. No. 164186, October 4, 2010) clarifies the obligations of contractors when construction defects appear and the rights of owners to demand correction. The case involved a school building in Las Piñas that developed widespread water seepage, cracks, and other deficiencies shortly after completion. The decision is a valuable guide for both property owners and contractors on who bears responsibility when construction goes wrong.

Facts of the Case

In 1985, Rudlin International Corporation engaged Financial Building Corporation (FBC) to construct a three-storey school building for a contract price of P6,933,268.00. The Construction Agreement required completion by April 30, 1986, with a penalty for delay. The parties later amended the completion date to June 10, 1986.

The building was inaugurated on June 15, 1986, in time for the school year. However, within two years, the structure showed serious problems: water seepage causing leaks, peeling paint, cracks on walls, and delamination of plywood. The waterproofing material used in the gutters had been changed from the brand specified in the plans to a substitute brand, allegedly with the owner's verbal approval.

When FBC sued for the unpaid balance of the contract price, Rudlin counterclaimed, asserting that the contractor was liable for defective work.

The Issue

The central question was whether the contractor, FBC, was liable for the construction defects—particularly the defective waterproofing—and whether the owner was obligated to pay the remaining contract balance despite these defects.

The Ruling

The Supreme Court held that FBC was liable for the construction defects. The Court rejected the contractor's defense that the owner's representative had verbally approved the change in waterproofing brand.

Under Section Fifteen of the Construction Agreement, all changes to the work had to be authorized by a written change order signed by both the Owner and the Architect. The Court emphasized that verbal assent, even if it occurred, was insufficient to modify the contract's requirements. The architect's letter demanding that FBC redo all waterproofing works using the specified brand, at no expense to the owner, was given full weight.

The Court also ruled that the contractor's warranty obligations remained in effect. Under the contract's guaranty-warranty provisions, the contractor warrants all work for one year from the date of final acceptance in writing by the owner. Since there was no formal turnover or written acceptance, the warranty period had not even begun to run.

Key Principles Established

Written approval is required for changes. Contract provisions requiring written change orders are strictly enforced. Verbal discussions, minutes of meetings, or alleged acquiescence by the owner's representative do not bind the owner to unauthorized modifications.

Contractors are responsible for subcontractors. Even if the owner suggested a particular subcontractor, the general contractor remains responsible for the quality of the subcontractor's work.

Use of the building does not mean acceptance. The fact that the owner moved in and used the building does not constitute formal acceptance, especially where defects are serious and the contract requires written acceptance.

Warranty periods start only upon formal acceptance. A contractor's warranty obligations do not begin to run until the owner has accepted the work in writing, as required by the contract.

Practical Takeaways

• Get it in writing. Owners and contractors should document every change to plans, specifications, or materials through formal written change orders signed by both parties. Verbal agreements are difficult to prove and may not be enforceable.
• Contractors should not rely on informal approvals. If an owner's representative suggests a substitute material, the contractor should insist on written approval from the architect or owner before proceeding.
• Owners should document defects promptly. Photographs, written complaints to the contractor, and letters from the architect are crucial evidence if disputes arise.
• Moving in is not acceptance. Owners who use a building despite defects do not waive their right to demand correction, especially where the contract requires formal written acceptance.
• Check warranty provisions carefully. Contractors remain liable for defective workmanship and materials within the warranty period, which begins only upon formal acceptance of the project.
