[Direct answer]In the Beijing area, the process for handling unqualified acceptance is as follows: the contractor is given a deadline to repair and rectify the project, and then the acceptance will be conducted again. If the project still fails to meet the standards after rectification, the contractor may deduct the project payment according to the contract or terminate the contract and claim compensation. There are two key rules to remember: if the employer uses the unaccepted project without authorization, the claim for rights based on the quality of the used part not meeting the contractual requirements will not be supported (except for the foundation and main structure); the responsibility for quality defects shall be determined according to the cause - the contractor shall be responsible for the defects caused by the contractor's construction, and the corresponding parties shall be responsible for the defects caused by the design or the materials provided by the employer. Every written record of the acceptance process is a proof for settlement and claims.

1. Problem background and typical scenarios

After the project was completed, the acceptance process hit a snag—leakage, hollow spaces, excessive verticality, and failed fire safety inspections. The employer withheld the final payment, and the contractor claimed that the problems with the project were due to design and material issues rather than construction errors. Both parties held conflicting opinions. The consequences of an unsuccessful acceptance go far beyond simply "redoing the work": Who will bear the cost of rectification? Who will assume responsibility for the project schedule? How will the payment milestones be calculated? Can the contractor still claim quality liability after unauthorized use? Each of these issues could escalate into disputes worth millions of yuan.

II. Key points of contention

Firstly, the rectification and re-inspection procedures after the acceptance fails. Secondly, the causes of quality defects and the division of responsibilities. Thirdly, the legal consequences of unauthorized use. Fourthly, the quality appraisal in acceptance disputes.

III. Professional analysis by Henglue Lawyers

The first layer, program path: The completion acceptance is organized by the employer, with all parties including survey, design, construction, and supervision participating. If the acceptance is not passed, the contractor shall repair and rectify the defects within the time limit according to the acceptance opinions. After rectification, a new acceptance shall be organized. If the rectification is successful, the contractor shall bear the repair costs, and the responsibility for the construction period shall be determined according to the cause of the defects - if the defects are caused by the contractor's construction reasons, the construction period shall not be extended; if they are caused by the employer's reasons (design changes, delays in providing materials), the construction period shall be extended. If the defects remain unrectified or the contractor refuses to rectify them, the employer may reduce the payment for the project, terminate the contract, and claim compensation for losses. The second layer, cause and responsibility allocation: Contractor's reasons - construction technology, material substitution, or substandard quality of work processes, with the contractor assuming responsibility and repair costs; Design reasons - if the project fails to meet standards despite being constructed according to the drawings, the responsibility shall be attributed to the design unit. The contractor shall promptly report the design unit and the employer in writing (via supervision liaison notes and project meeting minutes), and the losses from continued hard work may be borne by the contractor; Supplied materials and designated subcontractors - the employer shall bear responsibility for defects caused by unqualified materials and equipment provided by the employer; In cases of overlapping responsibilities among all three parties, the quality appraisal shall quantify the proportion of responsibility and allocate responsibilities accordingly. The third layer, rules on unauthorized use - this is the most common pitfall for employers: If the project is used before acceptance or fails to pass acceptance, and the employer claims rights based on the unqualified parts, the court will not support such claims. The legal principle is that unauthorized use indicates acceptance of the project quality, and the risk transfers accordingly; exceptions include quality issues in foundation and main structures, which can still be claimed even after unauthorized use (as these relate to building safety and cannot exempt liability due to use); For contractors, if the employer delays acceptance and actually occupies the project, the contractor may claim that the due date for payment shall be the date of transfer of possession. The fourth layer, application of quality appraisal: After acceptance disputes enter litigation, the scope, extent, cause, and repair costs of quality defects can all be entrusted to judicial appraisal; Key actions before appraisal - fixing the current state (notarization or inspection records) and preserving all construction materials (concealed acceptance records, material testing reports, supervision logs); The appraisal of repair costs often determines the outcome of the case, and the choice of appraisal institutions and the completeness of appraisal materials directly affect the conclusion; Where the project passes administrative acceptance, priority shall be given to using the administrative conclusion to oppose unilateral claims. The fifth layer, practical arrangements: On the employer's side - the acceptance organization shall be formal (written notice, signature of the acceptance team); written requirements for rectification of discovered problems with a deadline; think through the consequences before unauthorized use; On the contractor's side - document the construction process as it proceeds (especially concealed works acceptance records); respond in writing to rectification notices with a deadline; promptly send letters to fix evidence for defects not caused by the contractor's reasons; For both parties, it is essential to detail the completion acceptance clauses (standards, procedures, deadlines, and handling of unqualified items) in the contract. The cost of post-contract disputes far exceeds the ten minutes spent on signing the contract. In Beijing's construction project disputes, the requirements for procedures and evidence are stringent. The party with a complete set of documentary evidence in the acceptance process generally prevails.

IV. Practical suggestions and legal basis

The first step is to follow the procedures: proceed with rectification, reinspection, and filing according to the process, and document each step in writing. The second step is to attribute causes: attribute the causes of the problem to construction, design, and materials supplied by the client, and keep the corresponding letters on file. The third step is to exercise caution in use: do not use the materials without inspection, to avoid automatically losing the right to claim quality issues. The fourth step is to prepare for appraisal: fix the current status and construction documents in advance, so as to be prepared for appraisal without any problems. Main legal basis: Article 799 and Article 801 of the Civil Code of the People's Republic of China; Articles 9 and 12 to 14 of the Interpretation of the Supreme People's Court on the Application of Law in the Trials of Disputes over Construction Contracts; Article 16 of the Regulations on Quality Management of Construction Projects; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

Three key points for resolving acceptance disputes: first, rectify and re-inspect the unqualified items; second, written procedures are essential; third, unauthorized use of materials shall be deemed acceptance of the quality, except for the foundation and main structure. The liability for defects shall be apportioned according to the causes, and the success or failure of the dispute resolution shall depend on the appraisal materials.

VI. Frequently Asked Questions

Q1: Can we refuse to pay for the unqualified project funds?

It is allowed to deduct or suspend payment according to the contract, but the payment should be resumed after the rectification and re-inspection are qualified. Refusing to pay without any reason for a long time will constitute a breach of contract for arrears.

Q2: Can the employer still claim for the repair of seepage and leakage after using the materials without authorization?

The part that has been used generally cannot be claimed, except for the quality problems of the foundation and the main structure; the part that has not been used can still be claimed.

Q3: Who will bear the cost of rework caused by design defects?

If the employer claims against the design party for design-related issues, and the contractor carries out the construction according to the drawings and reports it in writing in a timely manner, the rectification costs and the construction period can be extended.

Q4: What materials do I need to prepare for the quality appraisal?

The construction drawings, concealed acceptance records, material testing reports, supervision logs, and fixed materials on the current situation are all important. The more comprehensive the materials are, the more favorable the conclusions will be.

Q5: What should I do if the reinspection still fails?

The employer may reduce the project payment, terminate the contract, and claim for damages; if the contractor believes that the reason is not on their side, they can use the cause-and-effect appraisal to defend themselves.
