What’s the Construction Process for Structural Steel Projects at ITSS?
If you are planning a construction project, one of the big questions is often, what actually happens during the steel work process?
At ITSS Engineering, we follow a clear step-by-step process to help builders, project managers, engineers, and architects keep everything moving smoothly. As an ISO 9001 certified company and SFC CC3 approved, quality and compliance are built into every stage.
How does a structural steel project start?
The steel work process usually begins when we receive the plans and prepare a quotation. Once the builder accepts the quote and the consented plans come through, we check those drawings against the original quoted plans.
If anything has changed, we update the quote as needed. This helps make sure pricing and scope are accurate before work moves forward.
What is the process before fabrication starts?
Before any steel is made, we complete our QA and job setup process. This includes reviewing:
- Paint Specifications
- Welding Specifications
- Required Certifications
- Inspection and Test Plan Requirements
This stage is all about making sure the project is set up properly from the start.
Are shop drawings part of the process?
Yes, shop drawings are a key part of the process.
Depending on the project, these are prepared either in-house or externally. If more detail is needed, we follow an RFI process to clarify information. This may happen through the builder or directly with the structural engineer and architect if requested and approved.
This helps ensure all details are confirmed before fabrication begins.
Who approves the drawings?
Once shop drawings are ready, they are issued for approval to the builder, structural engineer, and architect.
After approval is received, the drawings are released for fabrication.
What happens during steel fabrication?
Once fabrication begins, plates are cut, structural steel members are ordered and processed, and material certifications are collected and saved to the project.
Beam assemblies are then fabricated in house by our Steelfab team and checked through our quality assurance process. Welding is also completed in-house by certified welders, following the required welding specifications.
How is the steel finished and protected?
The finishing process depends on the project specification.
If the required coating can be completed in house, we do that ourselves. If galvanising or zinc wire spray is needed, the steel is sent offsite and transported by the Warkworth Cranes team.
Any required galvanising certificates and paint thickness records are also completed as part of the job.
What happens before installation onsite?
Before installation, our onsite riggers and the Warkworth Cranes team work closely with the builder to confirm access, timing, and methodology.
This helps make sure installation runs safely and efficiently.
What happens at the end of the project?
Once installation is complete, we compile the final QA documents and complete the PS3 and project completion documentation for the builder.
Why does this process matter?
A clear process helps reduce delays, improve communication, and make sure the finished steel work meets the required standards.
At ITSS Engineering, we believe good results come from good systems, strong communication, and getting the details right from day one.
