If earthmovers and trenching contractors in Contra Costa County have employees, they're required to have workers' compensation insurance for your protection. Excavation, grading, and trenching are among the most hazardous construction operations. If a worker is injured on your property and the excavation company doesn't have worker's comp, you could be liable to pay for the injuries and your own insurance may not cover that cost. Trenching and excavation present the possibilities of cave-ins, falls, falling loads, hazardous atmospheres, and accidents with earthmoving equipment such as bulldozers and backhoes.
Excavators in Contra Costa County are not required by law to have general liability insurance; however, all excavation, grading, and trenching contractors bearing The Prime Buyer's Report—TOP 10 designation have general liability insurance coverage which reimburses their client in the event of any damages, in addition to passing all other requirements for certification as Prime Buyer's Report—TOP 10 such as phone calls with previous clients, hiring only documented workers, verified license and workers' comp insurance, clean complaint record, and more.
Excavation vs Trench
Excavation is often defined as any man-made cavity, trench, cut, or depression formed by earth removal. This includes excavations for anything from cellars to highways, dirt removal to landslide repair.
A trench is formally defined as a narrow underground excavation that is deeper than it is wide, and no wider than 15 feet.
No matter how many shoring, trenching, and backfilling jobs an excavator or grading contractor in Contra Costa County has done in the past, they must approach each new job with complete preparation and care, and the success of excavation work is dependent upon thorough planning. When a trenching contractor waits until after the work has started to correct mistakes in shoring or sloping, it slows down the project, adds to the cost, and increases the chance of a cave-in or other excavation failure.
Before preparing a bid, excavation & earthwork contractors should be learning as much as possible about your property site and the materials needed to perform the work safely. Things they should be assessing on your job site prior to submitting a bid include surface and ground water, utility lines both overhead and underground, weather, location of the water table, surface and ground water, soil conditions, traffic, and proximity of nearby structures. A trenching contractor who prepares a bid without this full assessment is more likely to charge you for cost overruns or miss your deadline.
To make that assessment, the trench contractor should be doing a jobsite study, observations, test borings for soil type or soil condition, and consultations with local officials and utility companies. Failure to do so means the excavator is unlikely to correctly determine the right cost and equipment necessary to do your project safely and on time.
