The University of Texas at San Antonio


The Biosciences Building at the University of Texas at San Antonio (UTSA) is a four-story structure, constructed circa 1995, with a modified bitumen roof system.


The building is a critical laboratory at UTSA, so special considerations were given to roof access and security as well as fall protection for maintenance personnel. Structural analysis and modifications to support a new security fence and new fall protection anchors on the existing structure were performed by in-house WJE structural engineers.

The bidding process was challenging, as this was a relatively small project that required several different trades. WJE and UTSA collaboratively phased the project to promote competitive bidding, reduce overhead costs on the project, and meet a tight project schedule.

During construction, WJE performed regular site visits and issued reports documenting deficiencies and worked with the contractor to facilitate corrections. WJE also reviewed the applications for payment, requests for information, and submittals. Since the building was occupied for active laboratory studies and the roof replacement required temporary shutdown of some of the critical exhaust equipment, tight coordination between all team members was particularly important.
