20 Florida-licensed underground utility & excavation subcontractors serve Fort Walton Beach (Okaloosa County). Browse listings below, or create a free* GC account to see phone and email and invite a sub to bid on your RFQ.
Underground utility and excavation subcontractors handle the wet and dry utilities below grade on a project — water mains, sanitary sewer, storm drainage, force mains, lift stations, valve and meter vaults, dewatering, and the site excavation and backfill that goes with them. On commercial and site-development jobs they price from the civil drawings and utility spec, coordinate with plumbing for building connection points and with paving on trench restoration, and pull permits with the local utility and water-management districts.

When a GC sends an underground utility RFQ, they're usually looking for a quote against a defined scope: the civil and utility drawing set with the related Division 33 spec section, a clear inclusion and exclusion list (water, sewer, storm, lift stations, dewatering, rock excavation, trench restoration), and the sub's read on long-lead items like lift station equipment and large-diameter pipe. For bid prep a GC typically wants pricing broken out enough to compare apples-to-apples, confirmation the sub priced to the spec book, and the sub's license and insurance on file.
Underground utility and excavation contracting in Florida is a state-licensed trade, regulated by the Construction Industry Licensing Board (CILB) under the DBPR. There are two tiers: a certified underground utility and excavation contractor (license prefix CUC) is authorized to work anywhere in the state, while a registered underground utility contractor (RU) is limited to the local jurisdiction that issued their competency card. Florida treats unlicensed contracting as a crime, so a GC confirming a sub's active CILB license is doing basic bid-prep diligence — which is why every underground utility sub in this directory carries its DBPR license number.

Certified underground utility and excavation contractors can take work anywhere in Florida. Registered underground utility contractors can only work in the local jurisdiction that issued their competency card.
The civil and utility drawing set with the Division 33 spec section, a scope inclusion and exclusion list (water, sewer, storm, lift stations, dewatering, rock excavation, trench restoration), any long-lead items, the bid deadline, and whether a site visit is required.
Yes. GCs post an RFQ and invite matched subs by trade and service area; invited subs are notified and can submit a bid for your bid prep.
Listings are seeded from public Florida DBPR license data, and a sub can claim its listing and upload a credential for a one-time review. The badge reflects what was reviewed: a verified state license earns License Verified — the usual path for an underground utility sub — a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows the Verified Pro umbrella.
