Erection Sequence & Planning
Pre-Erection Planning
Erection sequence is the planned order in which structural steel members are lifted, placed, and connected. A proper erection sequence ensures structural stability at every stage and prevents overloading the crane or the partially completed structure. The erection plan is developed by the steel erector in coordination with the engineer of record and addresses crane placement, member delivery order, and connection sequencing.
Key elements of an erection plan include:
- Crane location and reach - the crane must be positioned to access all members without excessive boom angles
- Member delivery order - steel is delivered in the order it will be erected, organized by sequence number
- Connection sequence - defines which connections are made first to ensure stability
- Temporary bracing plan - identifies where bracing is needed before permanent connections are complete
Erection Drawings
Erection drawings (erection plans) show the placement of every member using piece marks - unique identifiers assigned to each steel member. Ironworkers use erection drawings to identify which piece goes where, the connection type at each joint, and the orientation of each member.
