Overview

Design Bid Build:
TxDOT employs
design
bid build project delivery method
when
:
  • District designs the project in house or hires a consultant to design the PS&E.
  • Construction Division (CST) assists in letting the project to a contractor.
  • Contractor constructs project after approval from Texas Transportation Commission.
Design Build: Larger
construction projects where a single contractor is hired to both design and build the project on an accelerated schedule.
Comprehensive Development Agreements (CDAs) may also be
used
as a form of design build project delivery. CDAs may include provisions for a developer to
