Steel Erection subcontractor insurance requirements
Define fabrication, delivery, lifting, erection and temporary stability responsibilities. Separate crane ownership and engineering obligations from the erector’s labor scope.
Start with your agreement, the work scope and the applicable state workers’ comp rules. Collect current policy evidence and the endorsements your agreement requires. A certificate summarizes information; it does not resolve every exclusion or condition.
Scope details that change the review
Lifting
Suspended loads can affect adjacent structures and people.
Temporary stability
Responsibility during erection can differ from the completed structure.
Engineering
Connection design or erection plans may create professional-service obligations.
Questions for the contractor and agent
- Who is responsible for temporary bracing and connection design?
- Which business supplies and operates lifting equipment?
- Does the policy scope include the structure type, height and erection method?
Documents to collect
- GL, auto and workers comp evidence
- Relevant professional and completed operations evidence
- Separate crane contractor and required endorsement records
Compare policy dates and limits against the signed requirements. Check the actual endorsement wording when the requirement depends on insured status, a waiver or the scope of operations. Keep unknown items pending and record the reviewer responsible for resolving them.
A hypothetical review
A steel subcontract includes connection design and crane procurement. The GC asks for the relevant professional and lifting evidence rather than treating all obligations as ordinary erection labor.
Renewals and scope changes
Review revised erection plans, new lifting contractors and policy renewals during phased work.
Choosing limits
These review questions do not establish a universal legal minimum for this trade. Owner contracts, project size, operations and applicable licensing rules can change what is required. Use the requirements generator for an illustrative starting schedule, then have the authorized risk owner and broker approve the actual requirements.
