Case Summary (G.R. No. 170596)
Key Dates and Procedural Posture
Trial court: Regional Trial Court of Manila, Civil Case No. 83‑19367 (initial judgment holding petitioners and Contech liable, with allocation). Court of Appeals: Decision dated May 11, 2005 (modified trial court award, held petitioners and Contech solidarily liable for full reconstruction cost). Supreme Court: G.R. No. 170596, decision rendered November 28, 2008 (petition for review granted; trial court judgment reinstated with modification). Applicable constitutional framework: 1987 Philippine Constitution (decision rendered after 1990). Applicable statutory provisions and doctrines: Articles 2176 and 2194 and Article 684 of the New Civil Code; doctrines of quasi‑delict, solidary liability of joint tort‑feasors, contributory negligence, and supervening negligence.
Factual Background
Petitioners contracted Contech in 1978 to construct the NSS Building. During excavation and construction, tenants of the adjacent LSG Building reported cracks, bent doors, falling concrete, tilted floors and distorted frames. Inspections revealed excavation close to the common boundary and exposure of the LSG Building foundation. Contech initially undertook repairs (announced completion in December 1979), but further deterioration continued; consultants later found differential settlement, recommended demolition and reconstruction, and estimated reconstruction cost at P8,021,687.00.
Claims and Relief Sought
Respondent sued petitioners and Contech for sums covering: (1) P8,021,687.00 (demolition and reconstruction); (2) P154,800.00 (consultant fees); (3) P543,672.00 (lost rental income); and (4) P10,000.00 as attorney’s fees. Petitioners moved to dismiss and asserted that the LSG Building had preexisting structural deficiencies and that other forces (e.g., earthquakes, poor maintenance) contributed to the damage. Petitioners filed a cross‑claim against Contech pursuant to their construction contract; Contech denied liability, asserted compliance with plans, and argued any owner claim was waived for delayed notice.
Trial Court Findings and Disposition
The trial court found defendants negligent for excavating near the common boundary without properly braced sheet piles, which permitted soil erosion and damage to the LSG Building. The court also found the plaintiff (LSG) guilty of contributory fault: originally a two‑storey building, the LSG had added two floors (third and fourth) without reinforcing foundations, thereby overburdening the foundation and contributing to progressive settlement. On that basis the trial court apportioned liability equally: ordered defendants (Ngo spouses and Contech) jointly and severally liable for 50% of reconstruction cost (P4,010,843.50) and held Contech to reimburse petitioners for any amount petitioners might pay to respondent; it denied other damage claims for lack of sufficient basis.
Court of Appeals’ Ruling
The Court of Appeals affirmed in part and modified the trial court. It rejected the trial court’s finding of respondent’s contributory negligence, concluding instead that the petitioners (as owner) and Contech (as contractor) were solidarily liable under Article 2194 for the full cost of demolition and reconstruction. The CA awarded P8,021,687.00 with interest from filing date, plus 10% of the principal as attorney’s fees and costs.
Issues Raised in the Petition for Review
Petitioners (spouses Ngo) raised three principal assignments: (1) CA erred in disregarding evidence showing respondent’s contributory negligence as proximate cause; (2) CA erred in holding petitioners jointly and severally liable with Contech despite lack of proof of petitioners’ negligence; and (3) CA unjustifiably awarded attorney’s fees (10% of principal) without legal or factual basis.
Standard of Review and Approach to Conflicting Findings
The Supreme Court emphasized that while it normally defers to lower courts’ factual findings, it will re‑examine evidence when the Court of Appeals’ findings diverge from those of the trial court. The trial court’s proximity to the witnesses and evidence gives its findings greater weight; where the trial court’s factual findings are more consistent with the record, the Supreme Court is inclined to uphold them.
Analysis of the LSG Building’s Structural History
Record evidence showed the LSG Building’s foundation was designed for a two‑storey structure. Although permits and construction history varied (initial permits in the 1950s, fire in 1966, addition of third and fourth floors completed in 1968), the key point is that the original foundation supporting two floors was retained when two more floors were added. Expert testimony and the E.S. de Castro report pointed to progressive settlement and recommended removing the added floors or complete demolition. The Supreme Court emphasized that the overburdening of an unchanged foundation by added floors plausibly contributed to settlement and could not be discounted as a cause of the structural failure.
Contributory Negligence and Apportionment
The Court adopted the trial court’s view that respondent’s decision to add floors without reinforcing the foundation constituted contributory negligence. Contributory negligence is conduct by the injured party that legally contributes to the harm by falling below the protective standard. Given evidence that the LSG Building’s foundation was inadequate for the four‑storey load, the Court agreed a reduction of the award was warranted and that equitable apportionment (50–50) satisfied substantial justice. Therefore the trial court’s allocation that respondent bear 50% of the reconstruction cost was supported.
Liability of Petitioners and Contech; Supervening Negligence
The Court also sustained the trial court’s finding that Contech failed to observe proper excavation safeguards (sheet piles were not properly braced), and that such negligence was the proximate cause of the damage. Under the doctrine of supervening negligence, where multiple negligent acts exist but one party had the last clear opportunity to avoid the harm, that party may be primarily liable. Construction work requires technical expertise; owners may reasonably rely on contractors’ technical care. Contech’s omissions in excavation protocol and failure to secure appropriate insurance (Contractor All Risk / Erection All Risk) were relevant in assigning primary liability to the contractor.
Joint Tort‑feasors, Solidary Liability and Reimbursement Between Co‑defendants
The Court discussed applicable Civil Code provisions: Article 2176 (liability for quasi‑delict), Article 684 (prohibiting excavation that deprives adjacent land/buildings of sufficient lateral or subjacent

Procedural Posture
- Petition for review on certiorari to the Supreme Court from the Court of Appeals (CA) Decision dated May 11, 2005 and its denial of motion for reconsideration in CA-G.R. CV No. 65553.
- Trial court: Regional Trial Court of Manila, Civil Case No. 83-19367; judgment rendered against defendants Ngo Sin Sing, Ticia Dy Ngo and Contech Construction Technology Development Corporation.
- CA: Affirmed trial court in part but modified, holding petitioners and Contech jointly and severally liable for the full cost of demolition and reconstruction (P8,021,687.00), plus interest, attorney’s fees and costs.
- Supreme Court: Granted the petition, set aside the CA decision, reinstated the trial court decision with modification directing Contech alone to pay P4,010,843.50; deleted CA award of attorney’s fees.
Parties
- Petitioners: Spouses Ngo Sin Sing and Ticia Dy Ngo — owners of the lot at 745 Caballero St., Binondo and project owners of the NSS Building.
- Respondent plaintiff: Li Seng Giap & Sons, Inc. — owner of the adjacent Li Seng Giap Building (LSG Building).
- Respondent cross-defendant/contractor: Contech Construction Technology Development Corporation — general contractor for the NSS Building project.
Facts: Construction, Occupancy, and Initial Complaints
- Petitioners in 1978 contracted Contech as general contractor to construct a 5-storey concrete NSS Building on their lot adjacent to the LSG Building.
- During construction, tenants of the LSG Building complained of defects: cracks on floors, bent steel door, falling concrete slabs.
- Inspection disclosed excavation by Contech close to the common boundary, exposing the LSG Building foundation.
- Petitioners, as a gesture, assured respondents that repairs would be undertaken by their contractor; Contech announced completion of repairs in December 1979.
- After repairs, additional defects appeared: tilted floors, cracks in columns and beams, distorted window frames, and continuous sagging causing concerns about habitability and safety.
- In 1981 LSG engaged engineers E.S. de Castro Ph.D. and Associates through Control Builders Corporation to investigate damages and structural integrity.
Expert Findings and Engineering Conclusions
- Consultants’ ocular inspection, measurement of differential settlement, structural analysis and sub-surface soil determination concluded that the LSG Building suffered differential settlement caused by excavation during construction of the NSS Building.
- The consultants concluded the structural failure resulted from differential settlement beyond safe tolerable limits and recommended complete demolition.
- Estimated cost of demolition and reconstruction: P8,021,687.00.
- E.S. de Castro’s report included the engineering recommendation that, from a purely engineering standpoint, demolition and rebuilding would be best; alternatively removal of the 3rd and 4th floors to retain ground and second floors only; leaving the building as-is would be unsafe.
Plaintiff’s Claims and Prayer for Relief
- Li Seng Giap & Sons, Inc. filed complaint against Ngo Sin Sing, Ticia Dy Ngo and Contech praying for:
- P8,021,687.00 for demolition and reconstruction costs;
- P154,800.00 for consultants (E.S. de Castro and Control Builders) fees;
- P543,672.00 for lost rental income during reconstruction;
- P10,000.00 as attorney’s fees.
Defendants’ Answers, Cross-claims, and Contractor’s Position
- Spouses Ngo contentions:
- LSG Building was structurally unstable and deficient since inception; originally constructed in 1966 without adequate provision for differential settlement; defects attributable to various external forces including earthquakes and improper maintenance.
- Cross-claimed against Contech, invoking contractual provision that third-party claims should be answered by the contractor.
- Contech’s contentions:
- Excavation did not reach the common boundary and was approximately eight (8) inches away.
- Adequate precautions were undertaken, including wood sheet piles along boundaries; all work was done according to approved plans.
- Alleged waiver/abandonment of petitioners’ claim against Contech for failure to notify Contech.
Trial Court Findings and Judgment (Key Points)
- Trial court found defendants negligent, specifically that excavation on petitioners’ lot was near the common boundary and that soil erosion would not have occurred if wood sheet piles were properly placed and braced.
- Also found plaintiff Li Seng Giap & Sons, Inc. not free from fault: the LSG Building was originally a 2-storey structure, and plaintiff added two more floors without providing necessary foundation and reinforcement, causing or contributing to sagging.
- Applied comparative fault reasoning and apportioned liability: allocated damages on a 50-50 ratio between plaintiff and defendants jointly and severally.
- Trial court judgment ordered defendants Ngo Sin Sing, Ticia Dy Ngo and Contech jointly and severally liable to pay plaintiff P4,010,843.50; other damages not awarded for lack of basis.
- Ordered Contech to reimburse petitioners Spouses Ngo for whatever amount they pay to plaintiff. Counterclaims of defendants dismissed.
Appeals and Positions on Appeal
- Both Li Seng Giap & Sons, Inc. and the spouses Ngo appealed the trial court ruling; Contech did not appeal.
- Plaintiff appealed trial court’s finding of contributory negligence and reduction of the award; argued building had shown no distress until excavation began and sought full reconstruction cost and related damages.
- Spouses Ngo appealed contesting joint and several liability with Contech and the imposition of attorney’s fees.
Court of Appeals’ Ruling (Summary)
- CA affirmed that respondent had a proven cause of action; excavation without sufficient lateral or subjacent support invaded respondent’s property rights.
- Held petitioners’ liability as project owners should be shared with the contractor under Article 2194 (solidary responsibility of two or more persons for a quasi-delict).
- Rejected trial court’s finding of contributory negligence against respondent; held spouses Ngo and Contech solidarily liable for the whole amount.
- Modified trial court decision: defendants ordered to pay P8,021,687.00 with 6%
