Frequently Asked Questions
Why does structural concrete work require higher GL limits?▼
Structural concrete work — foundations, load-bearing walls, parking structures — directly affects building integrity. A failure can result in partial or complete structural collapse, causing catastrophic property damage and potentially fatal injuries. Remediation costs for structural concrete defects routinely exceed $500K, making $2M/$4M GL limits prudent for this type of work.
How long should completed operations coverage last for concrete and masonry work?▼
For structural work, require completed operations coverage for a minimum of 5 years, though 10 years is preferred. Concrete defects such as improper mix design, inadequate reinforcement, or poor curing can take years to manifest as cracking, spalling, or water infiltration. The statute of repose for construction defects in most states ranges from 6 to 12 years.
What is the silica dust concern for masonry work?▼
Cutting, grinding, and drilling concrete and masonry generates respirable crystalline silica dust, which causes silicosis and lung cancer. OSHA's silica standard (29 CFR 1926.1153) sets strict exposure limits and requires dust controls, monitoring, and medical surveillance. Verify that the contractor has a written silica exposure control plan and uses appropriate dust suppression methods, especially when working in or near occupied buildings.
Should I require professional liability for concrete and masonry contractors?▼
Professional liability is recommended when the contractor is providing mix design, structural calculations, or engineering services as part of the project. For straightforward flatwork or tuckpointing performed to architect or engineer specifications, professional liability is not typically required. If the project involves any design-build elements or the contractor is making engineering decisions, require at least $1M in professional E&O coverage.
Do concrete & masonry contractors in Michigan need a license?▼
Licensing requirements for concrete & masonry contractors vary by municipality in Michigan. Check with your local licensing board and always request proof of current licensure on the COI.
