Table Mesa RTD Parking Structure Expansion
Boulder, Colorado

This two story, eight hundred and twenty-two car addition to an existing three-story parking garage presented some interesting problems. Since the first three levels were built in 1991, we have changed building codes three times, and the required design loads under the 1997 UBC where much higher than these required by the 1988 UBC. Fortunately we could accommodate the 1997 Uniform Building Code loads. Because of its size the addition required providing an elevator adjacent to the north stairs with associated spandrel block outs and their new vertical supports. The construction administration phase also required attention to detail since some of the existing connections required retrofitting to transfer the imposed horizontal loads. The most challenging portion was to provide 2'-0" wide x 2'-4" deep precast planters supported by the exterior building spandrels.
