Acceptance production procedure is the stage that decides whether the quality of the project is guaranteed to be put into operation or not. Today, acceptance will need to strictly comply with current standards. In this article, let's learn about the regulations and technical requirements of the steel structure acceptance process according to TCVN 170:2007!
1. Acceptance standards for steel structures
Steel structure projects, especially prefabricated steel buildings, are completed by assembling many components, so all steel structures are closely related to each other. Complying with acceptance standards is mandatory to ensure quality as well as the safety and durability of the project.
Below are the acceptance standards for steel structures TCVN 170:2007:
- Before being shipped, all structures must be inspected by technical staff of the manufacturing unit.
- When conducting acceptance, the parameters of the components must comply with the requirements of this standard. Technical standards or guidelines applicable to specific components and design documents.
- For mass-produced structures, quantities, methods and inspection plans (including sample selection) must be prepared according to standards or technical instructions applicable to each specific structure.
- In the case of single and small production structures, inspection measures and plans (including sample selection) must be clearly specified in the design documents.
- Based on the quality requirements of the components and the parameters of the prescribed working mode, input inspection, manufacturing inspection and acceptance inspection must be carried out according to the list of criteria and measurements. Measurements are listed in Table 1 below.
- The results of inspection of input materials, processing and acceptance must be recorded in the technical inspection log, laboratory documents or other documents. The test results parameters must be recorded in the above documents and must meet the requirements of the design documents for the structure.
Table 1: Test format and parameters
Testing the composite ability, load-bearing capacity and stiffness of components needs to be carried out strictly, especially when they are specified in applicable standards, technical instructions and design documents. for each specific structure. The diagnostic process will be performed by observing from the outside to check compliance with the requirements of the standard, to determine where defects may appear in the structure.
2. Steel structure acceptance process
The contractor organizes the internal acceptance process and then creates an acceptance request form to send to the investor. The investor conducts acceptance based on the request form from the contractor. Contents that need to be done during the acceptance process include:
- Review the documents provided by the contractor to support the work acceptance process.
- Inspect objects for acceptance at the field or at the factory.
- Evaluate the conformity of details, parts or structures against designs, construction standards and technical guidance documents.
- When acceptance is completed, it is allowed to proceed with the next work.
Acceptance work should be recorded in the acceptance record. Those directly involved in the acceptance process must sign and clearly state their personal information in the acceptance record.
