Design-Build Contractors in Texas: What to Know
Design-build is a project delivery method in which a single entity holds contractual responsibility for both the architectural/engineering design and the physical construction of a project. In Texas, this model operates across commercial, industrial, institutional, and public infrastructure sectors, governed by a combination of state procurement statutes, licensing board requirements, and local code authorities. Understanding how design-build is structured — and how it compares to traditional project delivery — is foundational to navigating Texas commercial construction at any scale.
Definition and scope
Design-build consolidates what are traditionally two separate contracts — one with an architect or engineer, one with a general contractor — into a single agreement with one responsible party, the design-builder. The design-builder may be a general contractor that employs or partners with licensed design professionals, an architecture or engineering firm with construction capabilities, or a purpose-formed joint venture.
In Texas, licensed design professionals remain subject to the Texas Board of Architectural Examiners (TBAE) for architects and the Texas Board of Professional Engineers and Land Surveyors (TBPELS) for engineers, regardless of whether they operate within a design-build entity. The design-build contract does not waive individual licensure obligations.
Scope coverage: This page addresses design-build delivery within Texas commercial and institutional construction. It does not address residential design-build, federally contracted construction governed solely by federal acquisition regulations, or projects in jurisdictions outside Texas. Texas-specific procurement and licensing laws apply; federal design-build frameworks (such as FAR Subpart 36.3) are outside scope. Adjacent topics such as Texas commercial construction contracts and Texas commercial contractor licensing requirements address components that intersect with but are distinct from this delivery method.
How it works
The design-build process moves through structured phases. A typical Texas commercial design-build project follows this sequence:
- Owner issues a Request for Qualifications (RFQ) or Request for Proposals (RFP) — The owner defines the project program, performance criteria, budget parameters, and evaluation criteria. On public projects, this process is governed by Texas Government Code Chapter 2269, which authorizes design-build for certain state and local government entities.
- Design-builder is selected — Selection may occur through qualifications-based, best-value, or competitive sealed proposal processes, depending on whether the owner is a public or private entity.
- Preliminary design and bridging documents are developed — In some models, the owner's architect produces bridging documents (partial design specifications) before handoff; in others, the design-builder holds full design responsibility from project inception.
- Design and construction proceed concurrently — The design-builder overlaps design phases with construction activities (a process known as fast-tracking), which can compress the overall project schedule.
- Single-source accountability is maintained — The owner holds one contract for any design errors, construction defects, or schedule failures, eliminating disputes over the design-construction interface.
For public agency projects in Texas, Chapter 2269 of the Texas Government Code sets the statutory framework authorizing design-build procurement for transportation, water infrastructure, and public facilities. The Texas Department of Transportation (TxDOT) has executed design-build contracts exceeding $1 billion on highway corridor projects under this authority.
Design-build differs from construction manager at-risk (CMAR) — another method authorized under Chapter 2269 — in one critical way: under CMAR, the owner retains separate design contracts and the construction manager provides a guaranteed maximum price but does not hold design liability. Design-build transfers design liability entirely to the design-builder.
Common scenarios
Design-build delivery is applied across distinct project categories in Texas:
Fast-track commercial development — Warehouse, logistics, and manufacturing facilities in high-growth Texas markets (Dallas-Fort Worth, Houston, San Antonio) frequently use design-build to compress time-to-occupancy. Industrial developers often pair design-build with Texas commercial concrete and foundation contractors to begin site work before full construction documents are complete.
Public infrastructure — TxDOT and regional transit authorities use design-build for highway expansions, bridge replacements, and transit corridor projects. Texas Water Code provisions also authorize water utilities to use alternative delivery methods, including design-build, for treatment plant and pipeline projects.
Tenant improvement and adaptive reuse — In urban core markets, Texas commercial tenant improvement contractors operating under design-build arrangements handle interior buildouts where speed, integrated MEP coordination, and cost certainty are priorities for commercial landlords and institutional occupants.
K-12 and higher education facilities — Texas public school districts and universities have used design-build under Chapter 2269 for science facilities, student housing, and athletic infrastructure, where the single-source accountability model reduces owner management burden.
Decision boundaries
Design-build is not appropriate for every project type. The following contrasts clarify where this delivery method fits and where it does not:
| Factor | Design-Build | Design-Bid-Build |
|---|---|---|
| Owner control over design | Lower — design is delegated | Higher — owner holds separate design contract |
| Schedule compression | Significant — phases overlap | Limited — sequential phases |
| Cost certainty early | Lower until design develops | Lower but price set at bid |
| Design liability | Single entity | Split between designer and contractor |
| Public procurement authority | Requires statutory authorization (Chapter 2269) | Default method; no special authorization needed |
Owners prioritizing design control or working with complex historic structures may find design-bid-build or CMAR more appropriate. Projects subject to prescriptive state review — such as those requiring Texas commercial building codes compliance review by the State Fire Marshal's Office — still require code-compliant design documents regardless of delivery method.
For projects involving prevailing wage obligations or minority-owned business participation goals, design-build entities are subject to the same requirements as traditional contractors. Those frameworks are addressed at Texas prevailing wage laws for contractors and Texas minority and women-owned contractor certifications.
Owners navigating selecting a Texas commercial contractor should evaluate project complexity, schedule pressure, and risk tolerance before committing to design-build. The Texas commercial contractor bid process also covers procurement procedures relevant to competitive design-build selection. A full overview of how this sector is structured is available at the Texas commercial contractor authority index.
