Replacement Office Building (ROB)


condo-hotel-office / education-k-12

In order to consolidate The University of Texas System operations from five antiquated buildings into one efficient location, the 19-story Replacement Office Building (ROB) and parking garage was conceptualized for downtown Austin. This facility replaced a number of older university buildings and lease spaces, resulting in reduced maintenance and operating expenses. This created Class A offices for use by the UT System with three floors of shell space to be leased to non-UT System entities. Studies conducted by the university indicate the move will yield a total estimated net savings of more than $125 million over 30 years.

As the Building Envelope Commissioning (BECx) Agent for the project, Zero/Six prepared the BECx specifications, plan and testing requirements to support the basis of design, owner requirements, and energy efficiency goals. Zero/Six conducted an extensive document review to identify deficiencies in systems integration and establish performance criteria for envelope assemblies; laboratory and field testing requirements were then developed to verify installation and functionality for an airtight and watertight enclosure upon completion. During the construction process, our inspectors conducted regular site visits to verify as-built systems were installed in accordance with the design intent, while resolving any field issues to ensure an air and water-tight envelope is achieved. Commissioning activities included functional performance testing, chamber tests and roof uplift testing in accordance with ASTM standards, which allowed for timely correction during construction. After project completion, Zero/Six performed an infrared survey at the Level 20 roof of the building to ensure the owner received a roofing assembly free of moisture intrusion.
