G.R. Nos. 169408 & 170144; April 30, 2008
Hanjin Heavy Industries and Construction Co., Ltd. vs. Dynamic Planners and Construction Corp.

FACTS

Hanjin was the main contractor for the Davao International Airport Project, and it subcontracted a portion to Dynamic. The subcontract was a unit price agreement, with the price later adjusted downward after re-measurement. Dynamic commenced work but encountered significant issues. Hanjin breached the contract by paying the stipulated down payment in ten installments over six months instead of within twenty days and by delaying payments for progress billings. Furthermore, Dynamic’s engineer identified critical design flaws in the structural plans, which Hanjin dismissed, insisting construction proceed. These flaws later materialized as cracks in the terminal building.
Dynamic suspended work in December 2002, claiming Hanjin’s payment delays and refusal to address the design defects justified the suspension. Hanjin treated this as abandonment, completed the work itself, and withheld retention money. Dynamic initiated arbitration before the Construction Industry Arbitration Commission (CIAC) to claim payment for accomplished work, retention money, and escalation costs.

ISSUE

The core issue was whether Dynamic was entitled to its monetary claims despite suspending work, and whether Hanjin’s own breaches and the existence of design defects affected the parties’ liabilities.

RULING

The Supreme Court affirmed the Court of Appeals’ modifications to the CIAC award, largely ruling in favor of Dynamic. The legal logic centered on reciprocal obligations and breach. First, Hanjin’s failure to timely pay the down payment and progress billings constituted prior material breaches of the subcontract. This justified Dynamic’s subsequent suspension of work under the principle that a party may suspend performance when the other is in default (Civil Code, Article 1169). Dynamic did not abandon the project but lawfully suspended work due to Hanjin’s defaults.
Second, the proven existence of design defects, initially flagged by Dynamic, undermined Hanjin’s claim that all problems were due to Dynamic’s poor workmanship. This finding affected the apportionment of costs for corrective works. On the specific monetary claims, the Court upheld Dynamic’s entitlement to the retention money, as it had substantially performed its obligations prior to the lawful suspension. However, the claim for escalation costs was denied due to a valid waiver clause in the contract. The award for foreign currency payment was also modified, with the Court ruling that the obligation to pay in dollars was novated by the parties’ subsequent conduct of conducting all transactions in Philippine pesos. The Court deferred to the factual findings of the CIAC, as supported by the CA, emphasizing that arbitral awards are generally binding absent a clear showing of grave abuse.
