While a lot of work in the erection of a steel structure can be done off-site, there is still precise and demanding work that takes place on the execution side. Prefabricated steel components must be delivered and assembled on-site into a frame, with cranes often required for the lifting and placing process. This requires a high level of coordination.
Once in position, these components must be connected. Generally, this is achieved through bolting, but site welding is also used. All this work must be performed to the highest level to ensure the structural soundness of the project. To ensure quality execution, site surveys must be performed, tolerances achieved, and documentation and certification must be completed.
