Engineering and construction contracts in China operate within the Civil Code, Construction Law, tendering rules, mandatory standards and project approvals. The written contract is central, but its enforceability and commercial effect can also depend on contractor qualifications, mandatory tender compliance, lawful subcontracting and consistency with the winning bid.
Before works begin, align the scope, drawings, technical standards, site conditions, approvals, price, programme and interface responsibilities. During performance, use disciplined notices and contemporaneous records; unsigned instructions, delayed approvals and informal payment arrangements often become the core of later disputes.
Subject to editorial and legal review. Contract treatment depends on project type, tender status, qualifications, facts and forum. Confirm current Chinese texts, local rules and the complete contract file before acting.
Choose the contracting structure
Map the employer, investor, project company, designer, general contractor, specialist contractors, suppliers, supervisor and operator. Decide whether the delivery route is design-bid-build, EPC, general contracting, construction management or multiple prime packages, then allocate every interface and retained employer duty.
Test validity and mandatory compliance
Verify participant qualifications, project approval, required tendering and the absence of unlawful transfer, illegal subcontracting or borrowed qualifications. The Supreme People’s Court’s Construction Contract Interpretation (II), effective June 30, 2026, addresses tender and qualification defects directly: pre-award negotiation of material scope or price and using a later tender to formalise an already negotiated contract can invalidate the winning contract, while a project that ceased to require tendering before suit is not invalid merely because no tender occurred when the contract was signed. Borrowed-qualification arrangements remain invalid. For tendered projects, material terms should remain consistent with the lawful winning contract.
Define scope and technical baseline
Reconcile the agreement, conditions, bills, specifications, drawings, employer requirements, bid documents and clarifications through a clear priority clause. Record design responsibility, performance criteria, codes, quantities, temporary works, utilities, testing and exclusions. Resolve gaps before mobilisation where possible.
Site, permits and employer inputs
Allocate land access, demolition, utilities, approvals, construction permit, surveys, geotechnical data, design information and third-party coordination. State when each input is due and what relief follows delay or inaccuracy. Early access should not be treated as proof that all statutory conditions are satisfied.
Price and measurement
Identify lump-sum, unit-rate, cost-reimbursable or hybrid elements; taxes; provisional amounts; price-adjustment rules; and measurement authority. Define which quantities and risks are included and how mistakes or changed conditions are treated. Under Interpretation (II), a fixed-price contract is generally not adjusted merely because labour or principal-material prices changed during the agreed period, unless the contract provides otherwise or the Civil Code change-of-circumstances rule applies. If a fixed-total-price contract is terminated and the parties cannot value compliant completed work, the court may determine the completed proportion using local official valuation standards or industry norms and apply that proportion to the fixed total. Align tender price, contract price and any lawful post-award adjustment.
Programme, delay and extension of time
Require an accepted baseline, updates, critical-path information and recovery plans. Address employer delay, variations, access, approvals, force majeure, law change, abnormal conditions, concurrent events and mitigation. Extension claims should identify cause, contractual basis, affected activities and supported time impact.
Instructions and variations
Specify who may instruct, required form, emergency authority, quotation, valuation and programme procedure. Keep a change register linking each instruction to drawings, labour, equipment, materials, time and approval status. Work performed without a controlled record can be difficult to value or attribute.
Payment and security
Define applications, certification, invoices, payment dates, retention, advance payment, set-off, final account and interest. Coordinate performance, advance-payment, quality and wage guarantees. The revised SME Payment Regulation effective June 1, 2025 restricts payment practices where the purchaser is an authority, institution or large enterprise and the supplier is an SME.
Subcontracting and labour chain
Confirm permitted scope, consent, qualifications, flow-down terms and direct obligations. Prohibit unlawful transfer, dismembered transfer and illegal subcontracting. Maintain worker identity, attendance, wage and payment records; contractor obligations are not eliminated by passing work down the chain.
Quality, inspection and acceptance boundary
Set inspection, testing, hold points, nonconformance, correction and document requirements. Separate contractual completion from statutory acceptance and filing. Detailed defect allocation and acceptance evidence belongs in the dedicated defects route, but the main contract must establish the mechanism.
Suspension, termination and takeover
Define triggers, notice, cure, site protection, materials, equipment, records, subcontract treatment, valuation and handover. Interpretation (II) supports an employer’s post-termination claim for delivery of the site and construction records, permits an application for evidence preservation before contractor exit, and sets specific starting points for return of quality retention after termination or exit. Before suspension or termination, check statutory and contractual rights, project safety, financing consents and evidence. Preserve the state of work, the exit condition and mitigation steps before access or physical conditions change.
Claims and project records
Maintain signed contracts, approvals, drawings, transmittals, instructions, daily logs, photos, labour and equipment records, measurements, tests, schedules, payment materials and meeting minutes. Separate notices for time, money and other relief where the contract requires it. A coherent chronology is often more valuable than a later narrative.
Dispute clauses and payment priority
Confirm governing law, court or arbitration agreement, preservation options and expert mechanisms. The Civil Code and judicial interpretations address a contractor’s priority right over construction price, including scope and an eighteen-month maximum exercise period. Interpretation (II) requires a judgment confirming the right to identify the protected price amount and corresponding project, excludes employer-caused suspension and idle-work losses from priority, and addresses exercise through a qualifying discount agreement, transferred claims and insurance, compensation or expropriation proceeds. Obtain advice before waiver, settlement, transfer or enforcement.
