How much does concrete cutting and coring insurance cost annually?

Concrete cutting insurance costs vary by services and revenue. Residential core drilling ($8K-$18K annually), commercial slab sawing ($15K-$35K), full-service cutting ($28K-$65K), structural modification specialists ($55K-$125K), and high-rise/infrastructure contractors ($95K-$200K+) for comprehensive coverage including GL, workers comp, auto, equipment, and specialized silica and utility strike coverage.

What liability limits do concrete cutting contractors need?

Liability limits depend on work type: residential core drilling needs $2M minimum, commercial slab sawing requires $5M, structural wall sawing needs $10M, and high-rise/infrastructure work requires $25M+ to protect against structural collapse ($2M-$8M claims), post-tensioned failures ($1.5M-$5M), and gas line explosions ($3M-$15M).

Is silica dust exposure covered under standard liability policies?

No, silica exposure requires separate Contractor's Pollution Liability coverage ($3,500-$15,000 annually) covering employee silicosis claims, third-party respiratory disease, environmental cleanup, and OSHA defense. Standard GL excludes pollution. Individual silicosis claims average $450K-$850K, with mass exposure events reaching $2M-$5M.

What is utility strike coverage and why is it critical?

Utility strike coverage provides $1M-$5M sublimits for embedded utility damage during cutting. Critical because standard GL excludes consequential damages. Covers electrical strikes ($50K-$800K), water main breaks ($150K-$2.5M flooding), gas explosions ($500K-$8M+), and fiber optic cuts ($100K-$3M business interruption). Costs $2,500-$12,000 annually.

Does workers compensation cover silicosis?

Yes, workers comp covers silicosis as occupational disease, but claims are catastrophic. Individual claims range $300K-$1M+. Single claim increases Experience Mod by 0.40-0.60 points, tripling workers comp premiums for 3 years. Mass exposure affecting multiple employees totals $2M-$5M. Requires OSHA silica compliance including wet cutting, ventilation, respiratory protection, and medical surveillance.

Cutting load-bearing walls without proper shoring causes catastrophic collapse - $2M to $8M claims
Post-Tensioned Slab Cutting
Cutting post-tensioned cables releases tremendous force causing explosive slab failure - $1.5M to $5M
Structural Column Modification
Weakening structural columns causes progressive collapse of multiple floors - $5M to $15M claims
Foundation and Basement Cutting
Compromising foundation integrity causes settlement and structural cracking - $800K to $4M

Core drilling severed post-tensioned cables causing explosive slab failure. 8 workers injured, two floors evacuated, engineering investigation costs.

$3.5M

Boston Residential Building (2019)

Load-bearing wall removal without shoring caused progressive collapse affecting 4 units. Residents relocated, emergency shoring, structural repairs.

Silica Exposure: The Silent Liability Crisis

Why concrete cutting contractors face escalating respiratory disease claims

OSHA Silica Standard Requirements

Permissible Exposure Limit (PEL)

50 micrograms per cubic meter (μg/m³) as an 8-hour time-weighted average

Required Engineering Controls

Water spray systems, local exhaust ventilation, HEPA-filtered vacuum equipment

Medical Surveillance

Common Vibration Damage

Cracked plaster and drywall in adjacent spaces
Foundation cracks in neighboring buildings
Broken windows and glass from sustained vibration
Tile and stone surface damage
Structural settling and slab movement
Displacement of building components

High-Vibration Operations

Wall sawing with large diameter blades (24"+)
Wire sawing of thick concrete (18"+ walls)
Large core drilling (12"+ diameter cores)
Jackhammer concrete removal adjacent to occupied spaces
Floor sawing in multi-story buildings
Continuous cutting operations exceeding 4 hours

Vibration Risk Factors

Historic buildings with unreinforced masonry
Occupied residential or medical facilities
Work within 25 feet of existing structures
Buildings with existing stress cracks
Soft or unstable soil conditions
Shared wall or foundation connections

Pre-Construction Condition Surveys: Essential Protection

What to Document Before Starting Work

Photograph all existing cracks, damage, and building condition
Video walkthrough of adjacent spaces and exterior facades
Written condition report signed by property owner or tenant
Seismograph baseline readings if high-vibration work planned
Drone footage of roof and upper building elevations

Professional Survey Benefits

Survey Cost Investment

$500 - $3,000

Professional condition survey by structural engineer or surveyor
