Texas Design-Build Construction
Texas design-build construction consolidates the design and construction phases of a project under a single contractual entity, fundamentally changing how owners manage risk, schedule, and cost. This page covers the structure of design-build project delivery in Texas, the statutory and regulatory framework that governs public and private applications, the scenarios where design-build is most appropriate, and the boundaries that distinguish it from alternative delivery methods. Understanding these distinctions is essential for owners, developers, and contractors navigating Texas construction project delivery methods.
Definition and scope
Design-build (DB) is a project delivery method in which a single entity — the design-build team — holds a contract with the owner for both architectural/engineering design services and construction execution. This contrasts with the traditional design-bid-build model, where the owner contracts separately with a designer and then puts completed construction documents out to competitive bid.
In Texas, design-build authority for public entities is established under Texas Government Code Chapter 2269, which was enacted to consolidate and modernize alternative delivery methods for governmental entities. Under this chapter, governmental bodies that meet the population thresholds or project value thresholds specified in the statute may use design-build without seeking individual legislative authorization (Texas Government Code Chapter 2269). Private sector design-build projects are governed primarily by contractual law and the broader provisions of the Texas Property Code and Business & Commerce Code.
Scope and coverage limitations: This page addresses Texas-specific statutes, agency rules, and procurement frameworks. Federal design-build projects in Texas — including those funded through FHWA programs administered by TxDOT — operate under separate federal acquisition regulations and are not fully covered here. Municipal utility districts and special-purpose districts may have additional enabling legislation that supersedes or supplements Chapter 2269. Projects located outside Texas are not covered.
How it works
The design-build process in Texas typically unfolds in structured phases:
- Owner defines project requirements. The owner produces a Request for Qualifications (RFQ) and Request for Proposals (RFP) that establish performance criteria, budget parameters, and functional requirements rather than prescriptive drawings.
- Qualifications-based shortlisting. For public projects under Chapter 2269, the governmental entity evaluates offerors on criteria including technical approach, past project experience, safety record, and financial capacity. Price is not the sole criterion at this stage.
- Proposal evaluation and selection. Shortlisted teams submit detailed proposals. Public owners score proposals using weighted criteria defined in the RFP. The contract is awarded to the "best value" proposer, not necessarily the lowest bid — a key distinction from Texas competitive bidding construction requirements under Chapter 2269, Subchapter B.
- Preliminary design and GMP or lump-sum negotiation. The selected DB entity develops schematic design to sufficient detail to establish a Guaranteed Maximum Price (GMP) or lump-sum contract figure.
- Design development and permitting. As design advances, the DB team coordinates permit submissions. Building permits, engineering approvals, and specialty permits are obtained in accordance with Texas construction permits overview requirements, including local building department reviews.
- Construction and integrated quality control. Because the designer is part of the construction team, design issues are resolved faster. However, the owner must maintain independent oversight; Chapter 2269 permits the owner to retain an independent engineer or owner's representative.
- Closeout and commissioning. The DB entity delivers a single set of as-built documents, warranty packages, and commissioning reports to the owner.
Safety obligations do not change under a design-build structure. The contractor of record remains responsible for job-site compliance with Texas OSHA construction safety standards, including 29 CFR Part 1926 fall protection, excavation, and scaffold standards enforced by the federal Occupational Safety and Health Administration.
Common scenarios
Design-build is most frequently used in Texas in the following contexts:
Highway and transportation infrastructure. TxDOT has used design-build extensively on major highway projects. Texas Transportation Code Chapter 223 authorizes TxDOT to use design-build for projects exceeding $50 million (Texas Transportation Code §223.201), and TxDOT maintains a dedicated design-build program office that publishes procurement guidelines and approved project lists.
Water and wastewater facilities. Municipal utilities and regional authorities procure treatment plant expansions and pump station projects as design-build to compress schedule. The Texas Commission on Environmental Quality (TCEQ) requires engineering review and approval of water and wastewater facility designs regardless of delivery method, per 30 TAC Chapter 217 and related rules (TCEQ Engineering Rules).
Commercial and industrial facilities. Private industrial clients — including petrochemical and manufacturing facilities — favor design-build for Texas industrial construction sector projects where schedule compression and single-point accountability outweigh the control benefits of traditional delivery.
K–12 and higher education. Texas school districts and universities are governmental entities subject to Chapter 2269 and frequently use design-build for new campus buildings, athletic facilities, and renovation projects.
Decision boundaries
Choosing design-build over Texas construction manager at risk or traditional design-bid-build involves evaluating several structural factors:
| Factor | Design-Build | Design-Bid-Build |
|---|---|---|
| Owner design control | Lower | Higher |
| Schedule compression | High | Moderate |
| Single-point accountability | Yes | No |
| Price certainty at award | Lower (criteria-based selection) | Higher (lowest responsive bid) |
| Public sector statutory authority | Chapter 2269 required | Chapter 2269 Subchapter B |
Design-build is generally less appropriate when the owner has detailed, fixed program requirements that must be competitively bid under prescriptive documents, or when the project involves significant public interest in transparent low-bid procurement. Projects with unclear scope at the time of procurement carry risk that the DB entity may price conservatively, resulting in higher initial contract values.
Texas construction contract requirements govern the structure of the design-build agreement itself, including provisions for change orders, retainage, and dispute resolution under Texas law.
