Case Digest (G.R. No. L-3452)
Facts:
The case involves Leighton Contractors Philippines, Inc. as the petitioner and CNP Industries, Inc. as the respondent. The events leading to the case began in 1997 when Hardie Jardin, Inc. (HJI) awarded the contract for the construction of its fibre cement plant project located in Barangay Tatalon, San Isidro, Cabuyao, Laguna, to Leighton Contractors. On July 5, 1997, CNP Industries submitted a proposal to Leighton to act as a subcontractor for the construction of the structural steelworks for the project, estimating a total cost of ₱44,223,909 based on a requirement of 885,009 kilograms of steel. This proposal was accepted by Leighton on July 15, 1997, which instructed CNP to commence work. However, revisions to the fabrication drawings that impacted the designs of various structural components were communicated to CNP on July 16, 1997, leading CNP to estimate an additional steel requirement of 8,132 kg, translating to a further cost of ₱13,442,882. Despite this, CNP did not r
Case Digest (G.R. No. L-3452)
Facts:
- Background of the Contract
- In 1997, Hardie Jardin, Inc. (HJI) awarded the contract for site preparation, building foundation, and structural steel works of its fibre cement plant project in Barangay Tatalon, San Isidro, Cabuyao, Laguna to Leighton Contractors Philippines, Inc. (petitioner).
- On July 5, 1997, CNP Industries, Inc. (respondent) submitted a proposal to act as subcontractor for the construction of the structural steelworks of the project, estimating the need for 885,009 kgs. of steel at a cost of P44,223,909.
- The proposal was accepted by petitioner on July 15, 1997, confirming a fixed lump-sum price for the work.
- Contract Formation and Scope of Work
- On July 28, 1997, the parties formalized their agreement by signing a subcontract which:
- Defined the scope of work as the completion of the structural steelworks according to the Main Drawing, Technical Specifications, and in accordance with the Main Contract.
- Specified that the subcontract was on a fixed lump-sum basis (P44,223,909) and not subject to re-measurement.
- Emphasized that the respondent was responsible for deriving its own quantities and that no additional payments would be made for errors in quantity.
- The contract required the completion of work within 20 weeks from the site access date (June 20, 1997), meaning completion on or before November 6, 1997.
- Revisions and Additional Work Costs
- Shortly after the subcontract was signed, petitioner revised the fabrication drawings for several structural columns, impacting the designs for roof ridge ventilation and crane beams.
- These revisions were communicated to the respondent on July 16, 1997.
- The respondent estimated that the design changes necessitated an additional 8,132 kgs. of steel costing P13,442,882.
- Despite this, the respondent did not renegotiate the fixed lump-sum price.
- Payment and Execution of the Work
- On July 29, 1997, petitioner paid 10% of the project cost (P4,422,390.90) as a downpayment.
- The respondent submitted weekly progress reports and billing statements:
- In the progress report dated August 12, 1997, respondent reiterated that the roof ridge ventilation and crane beams were not part of the scope of work covered by the fixed price.
- Respondent presented the additional cost estimates in the same progress report.
- Respondent, however, continued the work under the fixed lump-sum contract.
- Project Delays and Takeover
- Due to the respondent’s inability to meet the project schedule, petitioner took over the project on April 27, 1998.
- At the time of takeover, the respondent had completed 86% of the work, for which petitioner had paid P42,008,343.69.
- Thereafter, the respondent claimed an outstanding balance of P12,364,993.94, asserting that the additional works (roof ridge ventilation and crane beams) were not included in the fixed lump-sum price.
- Dispute and Prior Adjudications
- The dispute was submitted to the Construction Industry Arbitration Commission (CIAC), where the main issue was whether the additional steel for the roof ridge ventilation and crane beams was covered by the lump-sum price.
- The CIAC determined that, because the fabrication drawings were not yet finalized at the time of the subcontract formation, the affected portions qualified as "additional works" and not as part of the agreed fixed scope.
- In its decision on March 19, 1999, the CIAC ruled in favor of the respondent by ordering petitioner to pay the balance plus additional works, along with the costs of arbitration and attorney’s fees.
- Petitioner subsequently assailed the CIAC decision before the Court of Appeals (CA), which, in a decision dated May 31, 2000, affirmed the CIAC ruling in its entirety.
- A motion for reconsideration was later filed by petitioner but was denied by a CA resolution dated November 20, 2003.
- Petitioner then elevated the recourse to the Supreme Court through a petition for review on certiorari.
- Petitioner’s Arguments on Appeal
- Petitioner contended that:
- The subcontract clearly defined the scope of work to include the roof ridge ventilation and crane beams.
- The contract was a fixed lump-sum one, and no additional payments were warranted despite the design revisions.
- Even assuming the design revisions constituted additional works, recovery of extra costs should have followed the strict procedure under Article 1724 of the Civil Code.
- Petitioner argued that the signing of the August 12, 1997 progress report by Simon Bennett (petitioner’s quantity surveyor) merely acknowledged receipt of the progress report without implying approval of the extra cost estimates.
Issues:
- Whether the additional steel costs incurred for the roof ridge ventilation and crane beams should be considered as part of the fixed lump-sum contract price.
- Did the revisions in the fabrication drawings, which resulted in increased steel requirements, constitute “additional works” not included in the fixed lump-sum contract?
- Was there an implicit modification of the contract when the progress report bearing extra cost estimates was acknowledged by petitioner’s representative, thereby subjecting petitioner to additional payment obligations?
- Whether the strict requisites of Article 1724 of the Civil Code were satisfied to justify an increase in the contract price.
- Was there any written authority by the petitioner ordering changes or adjustments in the scope of work?
- Was there any written agreement between the parties on an increased price corresponding to the cost of the additional works?
- Whether the parol evidence rule, as embodied in Section 9, Rule 130 of the Rules of Court, precluded the introduction of evidence suggesting a subsequent modification of the written subcontract.
