Currently, several factors influence the safety of prefabricated building construction, including:
– Omissions in node 1 and structural design
– Limited collaborative effect during the construction process
– Inadequate monitoring of construction quality, failing to meet strict 100% requirements
Therefore, to ensure construction safety and quality, the following aspects must be addressed before starting the project.
Enhance Collaboration
Strengthen the coordination between design and construction teams to ensure that all departments—design, construction, and decoration—share consistent information sources, maintain smooth communication, and collaboratively resolve any information conflicts.
The key to construction safety lies in having contingency plans that cover every stage before, during, and after construction. This is especially critical for comprehensive projects with tight schedules, short construction periods, and high-quality requirements typical of prefabricated buildings. Blocking of information must be avoided to prevent safety hazards.
Follow the principles of prevention, in-process control, and post-reflection to manage the entire project lifecycle. During the preparation stage, verify and inspect PC component information, check embedded parts, confirm steel bar positions and specifications, examine component appearance for defects, measure component dimensions, review component spot checks, and ensure the special construction plan is complete.
Throughout construction, carefully check that installation quality and component positioning meet standards, verify that node grouting complies with requirements, and ensure anchoring steel bars adhere to regulations. At project completion and acceptance, organize and verify the completeness and accuracy of project information, inspect concealed works, assess the quality acceptance of prefabricated subprojects, and protect finished products.
Successful prefabricated construction depends on high-quality collaboration among construction teams, designers, decorators, producers, and mold developers, supported by a robust quality management system to guarantee safety.
Leverage Advanced Technology
Design Phase
During design, Building Information Modeling (BIM) utilizes 3D modeling and provides multiple data interfaces for various stakeholders. Once design is finalized, 2D drawings accurately describe the position of each component. Collision detection tools identify and resolve conflicts across different disciplines promptly, allowing for necessary adjustments or solutions.
To ensure reasonable node design, structural safety, and compliance with national building regulations, repeated verification with BIM and other technologies is essential to confirm the technical feasibility.
Production Phase
In the production phase of precast concrete (PC) components, BIM data ports allow direct access to component information. RFID chips embedded in components enable real-time tracking of production progress, transportation details, and assembly locations. This data supports continuous safety monitoring during construction and helps identify potential safety issues early.
Given the large volume of PC components in prefabricated buildings, establishing a robust Internet of Things (IoT) system is especially important.
Construction Phase
During construction and assembly, integrating BIM with RFID technology effectively prevents problems such as component misuse or loss, which can occur due to the sheer number of PC components involved.
Strict Quality Supervision
Develop a comprehensive quality monitoring and supervision system for prefabricated buildings. This system should cover material quality, component integrity, critical node assembly, testing, and acceptance procedures.
Key Points for Installing Prefabricated Staircase Boards
When installing prefabricated stair treads, pause slightly about 500mm above the work surface. Adjust the orientation according to the direction of the stair treads and move slowly to prevent damage caused by shaking or folding. Once roughly in place, use a pry bar to fine-tune the position based on control lines, then weld and secure the treads after adjustments.
