Quality responsibility and obligation of the construction unit

First, accurate test site collection 1. We should master the quality responsibility of the general contractor. 2. Should master the witness sampling and inspection system of construction inspection. The proportion of samples and materials for witness sampling and inspection shall not be less than 30% of the number of samples specified in relevant technical standards. The following test blocks, test pieces and materials must be witness sampled and inspected: (1) concrete test block of load-bearing structure; (2) Masonry mortar test block for load-bearing wall; (3) Samples of steel bars and connecting joints used for load-bearing structures; (4) Bricks and small concrete blocks for load-bearing walls; (5) Cement for mixing concrete and masonry mortar; (6) Additives used in load-bearing structure concrete; (7) Waterproof materials for underground, roof and bathroom; (8) Other test blocks, test pieces and materials required by the state to witness sampling inspection. 3. We should master the construction quality inspection system and pay special attention to the quality inspection of concealed works. 4. The repair of construction projects and the division of responsibilities should be mastered. Second, the high-frequency question and answer point 1. Joint and several liability is mentioned in many places. How to master? A: Simple memory, as long as it involves general contracting and subcontracting, safety, quality, contract management and breach of contract are similar. Taking quality as an example, the Regulations on Quality Management of Construction Projects stipulates that if a construction project is contracted in general, the general contractor shall be responsible for the quality of the project. If the general contractor subcontracts the construction project to other units according to law, the subcontractors shall be responsible to the general contractor for the quality of the subcontracted project in accordance with the stipulations of the subcontract, and the general contractor and subcontractors shall bear joint and several responsibilities for the quality of the subcontracted project. The subcontractor shall accept the quality management of the general contractor. When quality problems occur in subcontracted projects, the construction unit or other victims may demand compensation from both subcontractors and general contractors. According to the provisions of the subcontract, the indemnifying party has the right to claim compensation from the other party for the compensation part that is not its own responsibility. 2. The construction unit found errors in the design documents and drawings during the construction. Can it be corrected? A: The Building Law stipulates that construction enterprises must carry out construction in accordance with engineering design drawings and construction technical standards, and shall not cut corners. The original design unit shall be responsible for the modification of the engineering design, and the construction enterprise shall not modify the engineering design without authorization. The Regulations on Quality Management of Construction Projects also stipulates that the construction unit must carry out the construction in accordance with the engineering design drawings and construction technical standards, and shall not modify the engineering design without authorization or cut corners; If the construction unit finds errors in the design documents and drawings during the construction, it shall timely put forward opinions and suggestions. 3. What are the requirements for on-site sampling? Answer: Under the supervision of the construction unit or the project supervisor, the construction personnel should take test blocks, test pieces and related materials related to structural safety on site and send them to quality inspection units with corresponding qualification levels for testing. 4. How to check and accept concealed works? Will the construction unit participate? Answer: Before the concealed works are concealed, the construction unit shall notify the construction unit and the construction project quality supervision institution. The construction unit shall conduct self-inspection first, and notify the supervision engineer in writing 48 hours before the concealed acceptance or intermediate acceptance. If the acceptance is unqualified, the construction unit shall modify and re-accept it within the time limited by the supervision engineer. The project quality meets the requirements of standards, specifications and design drawings. If the supervision engineer fails to sign the acceptance record after 24 hours of acceptance, it will be deemed as approval, and the construction unit can continue to carry out concealment or construction. 5. What is the relationship between rework and repair? Answer: Rework refers to the re-construction when the project quality does not meet the specified quality standards and cannot be repaired; Repair refers to the repair of the project to meet the requirements of quality standards when the quality of the project does not meet the standards, but it is possible to repair it. 6. Is the construction unit responsible for the maintenance of quality problems not caused by the construction unit? Answer: The construction unit should also be responsible for repairing the quality problems not caused by the construction unit, but the responsible party should be responsible for the losses and repair costs caused thereby. 7. Can inspectors recommend or supervise building materials, components and equipment? Answer: The regulation of engineering quality inspection is: (1) Inspection personnel shall not be employed by more than two inspection institutions at the same time; (two) testing institutions and testing personnel shall not recommend or supervise the production of building materials, building components and equipment; (3) The testing organization shall not have affiliation or other interests with the organizations authorized by administrative organs, laws and regulations with the function of managing public affairs, and the design units, construction units and supervision units related to the tested projects; (4) Testing institutions shall not subcontract testing business; (5) Testing institutions shall be responsible for the authenticity and accuracy of their testing data and testing reports.
