Hiring an Excavation Contractor in South Dakota
Buildermuse currently lists 6 excavation contractors in South Dakota, averaging 4.8 stars across 93 verified Google reviews. That is an unusually strong field — when nearly every firm clears 4.8 stars, response time and availability become the real differentiators, so call two or three rather than only the top result. Most of the crews above operate out of Sioux Falls, Aberdeen, and Rapid City.
South Dakota does not require a state-level general contractor license. Cities like Sioux Falls and Rapid City have their own requirements. State-level licensing exists for electrical and plumbing. With no statewide license for this work, checking city and county requirements — plus active insurance — falls on you as the hiring party.
Labor is the biggest line item on most bids, and the South Dakota market sets the floor: construction workers here average $32.05 an hour — about $66,664 a year — across 30,910 workers statewide, per Bureau of Labor Statistics data. Use that figure as a sanity check when comparing quotes — a bid priced far below market labor rates usually means subcontracted or uninsured crews.
