The court found coverage was properly denied based on the subcontractor's failure to follow contract specifications in blasting at the job site. Westfield Ins. Co. v. Carpenter Reclamation, Inc., 2014 U.S. Dist. LEXIS 130752 (S.D. W. Va. Sept. 18, 2014).

Carpenter was hired by the Board of Education (BOE) to perform preliminary site clearing, demolition, rock excavation, and establishment of sub-grade for a building. Carpenter was to excavate to 3.5 feet below the floor subgrade so that plumbing and other utilities could be installed.

Carpenter, however, blasted to depths deeper than required, including some areas that were up to nine feet. The BOE sued, alleging over-blasting and having to pay the cost of remediating the problem, along with breach of contract issues.
