What should general contractors look for in concrete subcontractors?

GCs should verify proper licensing and commercial insurance, bonding capacity for project size, crew size and equipment capabilities, scheduling flexibility and reliability, experience with similar commercial projects, quality workmanship standards, clear communication and responsiveness, established local reputation, and ability to coordinate with other trades.

What insurance should concrete subcontractors carry?

Concrete subs should carry commercial general liability with adequate limits, workers' compensation coverage, automobile liability for vehicles and equipment, completed operations coverage, and ability to provide additional insured endorsements naming the GC. Verify current certificates before contract execution.

How do you evaluate a concrete sub's capacity?

Evaluate crew size and skilled labor availability, equipment ownership or access, ability to handle project size and complexity, capacity for multiple concurrent projects, scheduling flexibility, backup resources for emergencies, and financial stability for materials and payroll.

Should you prequalify concrete subcontractors?

Yes, prequalification saves time and ensures quality. Establish prequalified concrete sub list based on credentials, experience, capacity, past performance, and financial stability. Update list regularly and maintain relationships with reliable subs for smoother project execution.

What should be in the subcontract agreement?
