Concrete subcontractors place the cast-in-place concrete on a project — footings, foundations, slabs on grade and slabs on deck, walls, columns, and the formwork, reinforcing, finishing, and jointing that go with them. On commercial jobs they price from the structural drawings and Division 03 spec, coordinate embeds and sleeves with the MEP trades, and carry the work that the rest of the building is built on top of, which puts their schedule on the critical path.
When a GC sends a concrete RFQ, they want a quote against the structural set and the Division 03 spec — mix designs, reinforcing schedule, slab thicknesses, joint layout, and finish requirements. Bids are typically broken out by cubic yard for placement and by square foot for slab work, with separate lines for formwork, reinforcing, and finishing. GCs want the bid to call out included mix designs, finish tolerance (FF/FL numbers where called for), and what's excluded — concrete testing, embeds furnished by others, slab moisture mitigation, sealers.
Concrete is not a separately state-licensed trade in Florida — there is no DBPR concrete-contractor classification the way there is for electrical or plumbing work. Structural concrete is most often placed under a general contractor's license (CGC/CBC/CRC), and standalone concrete subs are regulated at the county or municipal level, where many jurisdictions issue a competency card. General-liability insurance — a current certificate of insurance — is the baseline a GC should confirm, which is why concrete subs in this directory typically earn their verified status through the insurance path rather than a license upload.
Usually no. Anchor bolts, steel embeds, leveling plates, and weld-on inserts are typically furnished by the steel or miscellaneous metals sub and installed by the concrete sub during the pour. RFQs should state who furnishes and who installs each category of embed. A clean concrete bid lists embed installation as included by others-furnished or excludes it entirely and lets the GC reconcile.
Concrete testing — slump, air content, cylinder breaks — is almost always carried by a third-party testing lab paid by the owner or the GC, not the concrete sub. The concrete sub is responsible for delivering mix designs that meet the spec and cooperating with testing on site. RFQs should state who pays for testing; bids typically exclude testing as a line item.
Standard commercial slabs are specified with Floor Flatness (FF) and Floor Levelness (FL) numbers in Division 03. A conventional commercial slab runs around FF 25 / FL 20; a tighter spec for warehouse or retail floors can call for FF 35 / FL 25 or higher. Concrete bids should price to the called-out tolerance and note the assumption — high-tolerance floors take more screeding labor and finishing passes.
Construction joints, control joints (saw-cut or tooled), and expansion joints are typically called out on a joint plan in the structural set. The concrete sub prices the joint pattern shown and installs control joints to the spec'd depth and timing. Sealants in the joints — silicone or polyurethane fills — are sometimes carried by the concrete sub and sometimes by the sealant sub. RFQs should call out which.
The badge reflects what was reviewed: a verified license earns License Verified, a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows both badges. Because concrete has no state license, the certificate of insurance is the credential most concrete subs upload, so Insurance Verified is the natural badge for the trade.
