CTRMA’s SH45SW Project
Central Texas Regional Mobility Authority (CTRMA)
Austin, TX
$77M

TWG provided coordination for the design-bid-build project in south Austin, TX. The project included specific environmental challenges, including karst features and its location within the sensitive Edwards Aquifer recharge zone. TWG staff coordinated the location and construction of utilities to ensure compliance with the environmental requirements while adhering to the project schedule. TWG also provided engineering of underground electrical duct bank.  The roadway project was left with all utilities outstanding and no special provisions pertaining to utility clearance dates, creating exposure to contractor claims. Our team coordinated with each utility owner, the CTRMA, the roadway contractor, and the project’s construction management consultant to ensure that no claims or construction delays were realized.
