In strict accordance with the design drawings and construction acceptance specifications and procedures, our company has completed all the work contents from a certain day to a certain day. For example, in civil engineering, the project * * * produced 482t of binding steel bars, poured 4320m3 of concrete and filled 8 19m3 of wall masonry, and successfully completed the construction of many subprojects.

Fourth, the project quality control:

1. Control of raw materials used in this project: After the reinforcement enters the site, it has been jointly accepted by the construction, supervision and construction, and recorded. Steel bar should have factory certificate and inspection report when entering the site, and it can be used in the project only after being sampled and rechecked by the supervisor. The welded parts of steel bars have witnessed on-site sampling inspection, which meets the standard requirements. All kinds of aerated concrete blocks and cement bricks have factory certificates and inspection reports.
