The work performed may include new work, additions, alterations, maintenance, and repairs.
Start the review with workers' compensation.
For Other Foundation, Structure, and Building Exterior Contractors, the saved research highlights workers' compensation, completed operations, contractual liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What specific trade work does the contractor perform — ornamental metalwork, curtain wall, welding, fire escapes, concrete forms, or a mix?
- What percentage of projects involve work at significant elevation, and what is the typical maximum working height?
- Does the operation include any on-site welding or cutting, and what hot work procedures and permit practices are in place?
- What is the split between direct employee payroll and subcontractor payroll, and how are subcontractor certificates of insurance tracked?
- Does the contractor perform any design-assist, engineering review, or inspection services (such as fire escape inspections) alongside installation work?
- What types of projects are typical — new construction, renovation, industrial, commercial, residential — and who are the primary clients or GCs?
- Are there any owned, leased, or operated aerial lifts, cranes, or specialized rigging equipment?
- What is the prior five-year loss history, particularly for workers' compensation and general liability?
