Concrete subcontractor insurance requirements
Distinguish flatwork, structural pours, cutting, drilling and concrete pumping. Equipment arrangements and silica-producing operations are important scope details to record.
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
Structural work
Defects can affect load-bearing elements and later construction phases.
Pumping equipment
Ownership, operator control and placement can involve separate contractors.
Cutting and dust
Sawing existing concrete can affect utilities and neighboring operations.
Questions for the contractor and agent
- Does the scope include structural work, post-tensioned slabs or concrete cutting?
- Who provides the pump, operator and evidence of liability for those operations?
- Are silica-related exclusions or restrictions relevant to the planned work?
Documents to collect
- GL and workers comp evidence for the placing contractor
- Insurance evidence for a separate pumping contractor
- Required completed operations and additional insured documents
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 flatwork vendor is awarded a structural podium pour. The reviewer does not assume the earlier sidewalk project establishes suitable policy scope for the structural work.
Renewals and scope changes
Review major scope changes and replacement pumping vendors before the next pour.
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.
