Construction Subcontractor Awarded Over 320,000 RMB in Unpaid Engineering Fees

Construction Subcontractor Awarded Over 320,000 RMB in Unpaid Engineering Fees

Case Overview

A construction subcontractor in Eastern China successfully sued a general contractor for unpaid engineering fees totaling over 320,000 RMB plus contractual penalties. The dispute centered on a foundation engineering subcontract for a scientific research building. The court ruled that the general contractor had improperly withheld payment, rejecting arguments that payment conditions had not been met and that certain claims violated the principle of res judicata.

Case Background and Facts

In August 2006, a foundation engineering company (the plaintiff, represented by Mr. Chen and Mr. Hu) entered into a subcontract agreement with a construction company (the defendant, represented by Mr. Xia). The contract required the plaintiff to perform bored pile and retaining pile work for a comprehensive science and technology building project. The contract specified a lump sum price of 2,780,000 RMB for the work scope, with payment tied to project milestones and final settlement after the owner’s audit. A key term required concrete supplied by the defendant to be deducted at 16% below the published information price.

The plaintiff completed all 227 engineering piles by October 8, 2006, and the retaining piles shortly thereafter. Testing confirmed the work met design requirements. In September 2009, a project department manager issued a payment plan acknowledging 636,488 RMB in outstanding fees, to be paid in three installments by November 2009. After the defendant paid only 100,000 RMB under this plan, the plaintiff sued for the remaining 536,488 RMB plus 8,340 RMB in contractual penalties.

Court Proceedings and Evidence

The plaintiff submitted nine pieces of evidence, including the subcontract agreement, the payment plan, payment vouchers, concrete settlement statements, a prior court judgment, and a forensic appraisal report. The defendant challenged the validity of the payment plan, arguing it was issued by an unauthorized person and did not constitute valid agency. The defendant also disputed the amount of concrete costs to be deducted and argued that payment conditions under the contract had not been fulfilled because the owner had not yet completed its audit of the project.

The court commissioned an independent appraisal of the retaining pile work, which determined the total construction cost was 428,047 RMB, after deducting 82,695 RMB for concrete supplied by the defendant. The court admitted the appraisal report, the subcontract, and payment vouchers into evidence, but rejected the payment plan as unauthenticated and the plaintiff’s unilateral calculations.

Court Findings and Judgment

The court found the subcontract valid and binding. It rejected the defendant’s argument that the plaintiff had waived its right to the 16% concrete price reduction by not claiming it in the first lawsuit. The court held that the first lawsuit sought only progress payments, not final settlement, and that waiver of contractual rights must be express, not inferred. The court calculated the engineering pile balance as 324,623.60 RMB after applying the 16% reduction to concrete costs.

On the retaining pile work, the court accepted the appraisal figure of 428,047 RMB, finding a balance of 103,047 RMB after deducting the 325,000 RMB already paid. The court also rejected the defendant’s argument that payment for the remaining 10% of fees was conditional on the owner’s audit, noting that the contract only required settlement after the owner’s审定 (review), not full payment by the owner. The court ordered the defendant to pay 320,416.90 RMB in total outstanding fees, plus 8,340 RMB in contractual penalties. However, the court upheld the defendant’s right to retain a 5% warranty deposit until five years after project completion.

Key Legal Principles

The court applied the principle that contractual rights are not waived by mere silence or omission in prior litigation. A party must clearly express an intention to waive a right. The court also held that payment conditions in construction contracts must be interpreted reasonably, and a contractor cannot indefinitely delay payment by relying on its own failure to complete settlement with the project owner. The court further applied the principle that breach of contract entitles the non-breaching party to agreed liquidated damages.

Practical Insights

This case illustrates the importance of documenting all communications and payment plans in writing, with proper authorization. Subcontractors should ensure that payment plans are signed by authorized representatives or bear company seals. The case also shows that courts will not allow general contractors to use unresolved owner audits as a shield against payment obligations to subcontractors. Parties should carefully negotiate warranty periods and retention provisions, as courts may enforce reasonable industry-standard periods even when the contract is silent.
