UW takeaway · AI logic + saved research

Start the review with completed operations.

For Glass and Glazing Contractors, the saved research highlights completed operations, jobsite operations liability, work at elevation. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.

Questions to ask

  1. What types of projects make up the bulk of the work — residential replacement, light commercial storefront, or larger commercial and curtain wall projects?
  2. Is any work performed at significant elevation — above two or three stories — and if so, what percentage of annual revenue does that represent?
  3. Does the contractor perform any stained glass, decorative glass, or historic restoration work?
  4. Are there employees in addition to the owner, and how many — and do any subcontractors supplement the crew?
  5. Does the shop cut, fabricate, or temper glass on-site, or is all glass purchased pre-cut for installation?
  6. What is the typical value of glass inventory and specialty panels on hand or in transit at any given time?
  7. Are there any general contractor relationships that require additional insured status, specific GL limits, or completed operations coverage for extended periods?
  8. What does the prior loss history look like, particularly for completed operations, glass damage, or employee injuries?
