Does distance matter for excavation work?
10 of the 12 contractors are based in Janesville, and the others reach it from within 10 mi. Machines travel on trailers, and moving them is charged as mobilization, so a firm from further out may add that cost while a closer one absorbs it. Ask how it is billed.
