Demolition contractors can prepare a redevelopment site for excavation by removing existing structures. The commercial and specialist contractors listed in this category also include drainage specialists, whose installations need to follow the planned site grades and discharge locations. Mark the boundary between excavation and pipe installation in the scope of work to avoid gaps or overlapping charges.
Commercial & Specialist Contractors
Foundation specialists within Commercial & Specialist Contractors work with the support requirements established by the structural design and ground conditions. A house lift needs a planned sequence for temporary support and foundation alterations, with house lifters and piling specialists involved before work starts. Licensing and inspection requirements differ by jurisdiction across the United States; confirm the applicable approvals with the local building department before setting the construction schedule.
How should underground utilities be checked before digging?
Contact 811 within the notice period required locally and wait for the required responses before excavation. Privately owned lines, such as those serving an outbuilding, may need a separate locating service.
Which credentials should a contractor provide?
Request evidence of insurance and any license required for the proposed work, then verify the license with the issuing authority. References from jobs with comparable ground conditions can help you assess relevant experience.
What makes site-work estimates comparable?
Give each bidder the same drawings and available soil reports. Ask them to identify allowances and exclusions, particularly for rock excavation or removal of unsuitable soil.
