This 72,000 SF, three-story building consolidates the radiation oncology operations at the University of Texas Southwestern Medical Center at Dallas. The facility includes:
- Nine total vaults, six being traditional linear accelerators
- High-dose rate brachytherapy
- CT imaging
- Exam/consultation space
- Academics offices
- Conference center
FOOT-THICK PRIMARY CONCRETE SHIELD
The 7.5-foot-thick primary concrete shield at the accelerator vaults required an extensive mass concrete thermal control plan to make sure that cracking, due to heat of hydration, was minimized to maintain the integrity of the radiation shield. Due to the expansive soils in the area and the strict requirements of the linear accelerator equipment, the vaults are all constructed on 36-inch-thick structural floor slabs with an 18-inch void space. The piers supporting the vaults average 100-foot deep, with 25-foot penetration into the bearing stratum.
The most unique feature of the facility is the reduced size of the linear accelerator vaults from 1,100 SF to just over 600 SF. This was made possible by eliminating the maze entry and adding a second shield door that accesses a technical corridor behind the vaults. Accommodations have been made to support a phase II expansion in the future that will add 30,000 SF to the facility, including six additional accelerator vaults.
This project received the Architectural Precast Association’s 2017 Award for Excellence in two categories, Medical & Government and Building Green.
