G.R. No. 143154 & 143177; June 21, 2006
Advanced Foundation Construction Systems Corporation vs. New World Properties and Ventures, Inc.

FACTS

New World Properties and Ventures, Inc. (New World) awarded Advanced Foundation Construction Systems Corporation (AFCSC) a contract to construct 69 bored piles for a lump sum of P36,000,000. After the Notice to Proceed was issued but before the formal contract signing, AFCSC proposed an amendment to exclude the removal of underground obstructions from its scope, requiring extra payment for such work. New World did not respond to this proposal and directed AFCSC to proceed. The subsequently signed contract did not incorporate AFCSC’s proposal. During construction, New World ordered several changes, including increased pile depths and diameters, which AFCSC billed as extra work. The project was completed over eight months late. During settlement, the parties reconciled a partial amount, but New World refused full payment, citing defective piles and disputing AFCSC’s claims for additional compensation for removing underground obstructions and other items.

ISSUE

The primary issue is whether the removal of underground obstructions and other disputed items constitute extra work entitling AFCSC to additional compensation beyond the original contract price.

RULING

The Supreme Court ruled in favor of AFCSC, affirming with modification the Court of Appeals’ decision. The legal logic hinges on the principle that work not included in the original scope of the contract, and which is ordered by the owner, constitutes extra work that must be separately compensated. The Court found that the removal of underground obstructions was not part of AFCSC’s original scope under the signed contract. Although AFCSC’s pre-signing proposal to exclude this work was not incorporated, the contract itself was silent on the matter, and the nature of the work was extraordinary and not ordinarily incidental to bored piling construction. Since New World directed AFCSC to perform this removal, it constituted a change order or extra work. The Court applied the doctrine of quantum meruit, entitling AFCSC to reasonable compensation for this additional work. Regarding the other disputed items, such as sonic pipe installation, the Court similarly found they were not part of the original contract but were necessary due to New World’s subsequent directives for testing, thus qualifying as extra work. The award was modified to specifically grant compensation for the removal of obstructions and the various tests, while other aspects of the lower court’s ruling on the reconciled amounts and interest were affirmed.
