Erection Drawings in Steel Structure
In modern steel construction, erection drawings are the most critical documents used on site. Before a single column is lifted or a single bolt is tightened, the site team relies on accurate erection drawings to understand where each steel member goes, how it connects, and the sequence in which it should be erected.
What is an Erection Drawing?
An erection drawing (also called an assembly drawing or erection scheme drawing) is a technical structural drawing that guides the on-site assembly of prefabricated steel members. It shows the exact position, orientation, and connection method for every steel component: columns, beams, purlins, bracings, and girts.
