Florida Design-Build Construction
Florida design-build construction is a project delivery method in which a single entity holds contractual responsibility for both the design and construction phases of a project. This page covers how design-build operates under Florida law, the regulatory framework governing it, how it compares to traditional delivery methods, and the scenarios where it is most commonly applied. Understanding these boundaries helps owners, contractors, and public agencies evaluate whether design-build fits a given project's scope, timeline, and risk profile.
Definition and scope
Design-build (DB) consolidates architectural or engineering design services and physical construction under one contract with one responsible party — the design-builder. This contrasts directly with the traditional design-bid-build (DBB) model, where an owner first contracts separately with a designer, then solicits bids from contractors based on completed drawings.
Florida statute codifies design-build authority for public entities under Florida Statutes § 287.055, the Consultants' Competitive Negotiation Act (CCNA), which sets competitive selection procedures for professional services including design-build firms. For transportation infrastructure, the Florida Department of Transportation (FDOT) maintains its own design-build program governed by FDOT Standard Specifications and Procedure Topic No. 625-020-010.
Private-sector design-build projects in Florida are not subject to CCNA procurement rules but must still comply with the Florida Building Code (FBC), administered by the Florida Department of Business and Professional Regulation (DBPR). Licensure requirements for the design-build entity's qualifier fall under Florida construction licensing requirements, with the design-builder typically needing a licensed general contractor and a licensed architect or engineer involved in the design component.
This page covers Florida-specific statutory and regulatory requirements for design-build delivery. Federal design-build frameworks — such as those under FAR Part 36 for federal construction — and interstate contracts are not covered by this scope. Projects crossing state jurisdictions or involving federal funding layers may carry additional compliance obligations outside Florida's scope.
How it works
Design-build projects in Florida follow a structured sequence:
- Owner defines performance criteria. Rather than producing a full set of construction documents, the owner prepares a Project Definition Document or Request for Proposals (RFP) that states functional requirements, performance standards, budget parameters, and schedule expectations.
- Competitive selection (public projects). Public entities procuring design-build under Florida Statutes § 287.055 must use a two-step qualification and proposal process: first shortlisting firms by qualifications, then evaluating technical proposals and price.
- Bridging design (optional). Some owners hire a separate "bridging architect" to develop partial design documents — typically rates that vary by region design — before issuing the RFP. The design-builder then completes the remaining design.
- Design development and permitting. Once awarded, the design-builder develops construction documents and submits for permits under the Florida construction permitting process. Building officials review plans against the FBC; no permit may be issued until signed and sealed drawings from a Florida-licensed professional are submitted.
- Construction and inspection. Construction proceeds under required inspections. The FBC mandates threshold inspections for buildings exceeding three stories or 50 feet in height, performed by a licensed threshold inspector independent of the design-builder.
- Closeout and certificate of occupancy. Final inspections, punch-list resolution, and certificate of occupancy issuance follow standard FBC procedures outlined under Florida construction project closeout.
Design-Build vs. Design-Bid-Build: Key contrasts
| Factor | Design-Build | Design-Bid-Build |
|---|---|---|
| Contracts | 1 (owner–design-builder) | 2+ (owner–designer; owner–contractor) |
| Schedule | Overlapping design/construction phases | Sequential phases |
| Risk allocation | Design-builder holds design error risk | Owner holds design error risk |
| Cost certainty | Earlier GMP or lump sum possible | Firm price only after full documents |
| Change order frequency | Typically lower | Typically higher |
Common scenarios
Design-build is most prevalent in Florida across four project categories:
- Transportation infrastructure. FDOT has used design-build delivery for highway interchanges, bridge replacements, and toll facility expansions. Projects under FDOT's program are catalogued through the Florida Department of Transportation construction procurement portal.
- Public buildings and institutions. School boards, universities within the State University System, and county governments use design-build for gymnasium, classroom, and administrative facility projects where schedule compression reduces carrying costs.
- Industrial and warehouse facilities. Tilt-wall and pre-engineered metal building projects in logistics and distribution often use design-build because the design-builder controls proprietary structural systems. These frequently intersect with Florida commercial construction contracts structured around performance specifications.
- Coastal and specialty construction. Renovation or replacement of structures near the Coastal Construction Control Line (CCCL) — governed by Florida Statutes § 161.053 — sometimes uses design-build to coordinate environmental permitting, structural engineering for wind loads, and construction under a single schedule. Wind load compliance under the FBC's High-Velocity Hurricane Zone (HVHZ) provisions remains mandatory regardless of delivery method; see Florida wind load requirements.
Decision boundaries
Design-build is not universally appropriate. Several factors determine whether it fits a project:
Favoring design-build: Owner has clearly defined outcomes but limited design staff; schedule compression has measurable value; project type is well-precedented (warehouse, parking structure, roadway); single-point accountability reduces litigation exposure.
Disfavoring design-build: Program requirements are not yet stabilized; the project involves extensive historic fabric requiring Florida historic preservation construction review; owner wants maximum design control; public procurement rules impose barriers that increase procurement cost.
Contracting structure intersects with bonding and insurance obligations. Design-builders on Florida public projects over amounts that vary by jurisdiction must furnish performance and payment bonds under Florida Statutes § 255.05 — the Public Works Bond statute. Florida construction bonding requirements details threshold values and bond form requirements. Lien exposure on private design-build projects follows standard Florida lien law procedure under Florida construction lien law, including notice-to-owner obligations.
Safety compliance on design-build sites is not reduced by the delivery method. OSHA 29 CFR Part 1926 construction safety standards apply regardless of contract structure, and Florida's construction safety regulations under the Division of Safety with DBPR carry additional state-level obligations.
