Steel structures are increasingly used in civil, industrial, factory, and warehouse projects thanks to their outstanding advantages such as high durability, quick installation, reusability, and flexible design. However, to maximize these benefits, the erection of steel structures must strictly comply with technical and safety standards.
Even a small mistake during construction can lead to major consequences such as structural deformation, workplace accidents, or costly repairs. Therefore, understanding correctly and executing properly is crucial. Join CMC Architects to explore the most important standards in today’s steel structure installation process.
✅ 1. Why is it necessary to comply with standards when installing steel structures?
Steel structures are not like brick, stone, or concrete that can be adjusted on site. Each component is pre-manufactured in the factory, transported to the site, and even the slightest deviation in dimensions, bolt tension, or alignment can affect the entire system.
👉 Complying with erection standards helps:
-
Ensure accuracy, stability, and load-bearing capacity of the structure
-
Minimize workplace accidents, especially when working at heights
-
Optimize project schedule, cost, and operational efficiency
🛠️ 2. Key technical standards in steel structure installation
🔧 TCVN 5575:2012 – Steel Structures – Design Standard
This is the foundational standard for designing, testing, and acceptance of steel structures in Vietnam. TCVN 5575 defines:
-
Material requirements
-
Load-bearing capacity
-
Welded and bolted connections
📐 TCVN 9347:2012 – Steel Structure Installation
This serves as a “guideline” during the on-site erection process, including:
-
Methods for positioning and aligning components
-
Regulations on permissible tilt and deflection
-
Step-by-step inspection and acceptance procedures
🛡️ Occupational safety requirements under Circular 04/2017/TT-BXD
Especially critical when working at heights or in factory environments:
-
Provide full protective equipment (safety harness, insulated shoes, etc.)
-
Implement fall and object drop prevention measures
-
Conduct regular safety training for workers
⚠️ 3. Common mistakes to avoid
Even professional contractors sometimes make mistakes due to:
-
Failure to check positioning before erection → Misalignment requiring reinstallation and delaying progress
-
Using the wrong type of bolts or insufficient tightening → Reduces load-bearing capacity and loosens over time
-
Skipping calibration or failing to check with a laser device → Causes misalignment between levels
💡 4. Solutions from CMC Architects – Safety as a Mandatory Standard
At CMC Architects, we strictly apply:
-
✅ Multi-disciplinary BIM coordination to detect technical conflicts right from the drawings
-
✅ Use of geodetic positioning and laser measuring equipment for precise alignment of each component
-
✅ Integration of QA/QC processes in both factory and site phases to ensure installation accuracy and maximum safety
📌 Conclusion: “Safety is not optional, it is mandatory”
Every tightened bolt and perfectly aligned beam is not just technical work – it is a commitment to the safety and durability of the entire structure. Steel structure erection is not merely “frame assembly” – it is the art of precision and standardization.
