Mountain America Credit Union Corporate Headquarters

As Utah’s tallest suburban office building with 11-stories totaling 327,600 sq. ft., this is the centerpiece of Sandy City’s new development area. This location offers the highest profile and visible building signage in the valley, prominently located adjacent to I-15. Striking architectural features include floor to ceiling glass, upscale finishes and an awe-inspiring panoramic views of the entire Salt Lake City valley.

According to the design team, several options were considered for the office tower. The final solution was structural lightweight concrete over metal floor deck supported by a gravity steel frame. Wind and seismic forces are resisted by concrete shear walls strategically located around stair and elevator cores. This solution provided the best economy while maximizing flexibility in the occupied spaces.

Some of the structural challenges included looking at several options for the foundation system. A driven pile system was eventually chosen. Another design challenge was coordinating the parking structure to accommodate access from the Hale Center Theater that was already underway in construction. The parking structure is constructed with concrete post-tensioned slabs and beams. A series of galvanized angles is attached to the parking exterior to support the exterior metal panel cladding and the large video board on the southwest corner of the parking structure.

Some unique aspects of the design of the office tower included cantilevered floor plates at levels two and three to minimize structure and create the outdoor patio on the west side of level three. An elevated walkway was designed between levels one and two to provide a protected means of egress without occupying valuable floor space on the first floor.
