Keeping with the trend of a more open corporate environment, all employees, including administrators, work in ergonomically designed workstations rather than enclosed office spaces. Meeting space is provided in a series of conference rooms situated along the spine of the building. A series of horizontal reveals at the base of the building created with formliners provide a textual “base.” Further, this same liner pattern was used at two corners of the building in conjunction with a curved metal roof to de-emphasize the very long façade. Tilt-up panels are interrupted with a glazing system in sections of the upper floor wall to further break down the length of the building.
Demonstrating flexibility and balancing construction costs, the tilt-up panels were designed exclusively as an exterior cladding. No provisions were made to resist seismic forces or building loads. Instead, a series of interior-braced steel frames serve as the structural system, significantly reducing the structural design requirements of the panels and allowing construction dollars to be allocated to other features.
New to the market
Since the 77,342-sq.-ft. Berkeley Building in Columbia, S.C., represented the first application of tilt-up technology for multistory construction in this geographic market, it was essential to convey the viability of the medium without sacrificing architectural appeal. Working in a new market with an inexperienced labor pool as well as a tight budget and schedule required close coordination by the design-build team. The tall windows and strong separation between the first level and top two levels make this project a stand-out.
The entryway to this Class “A” office building consists of a 117,000-lb. spandrel panel that spans 44 ft. and sits on two U-shaped panels to create a dramatic and focused point of entry. The main entrance door is recessed into a 4-ft. thick free-standing panel that is surrounded by curtain wall glass, leading into a grand two-story atrium. Textured paint covers the entire building and provides a traditional façade replicating quarried stone masonry. The EIFS cornice bands and Tuscan columns further define the character of the building. This is the first of five office buildings for the park.
Rehabbing for revitalization
Located in an area of Spokane, Wash., that is in the throes of revitalization, the 24,772-sq.-ft. Iron Bridge 1401 Building is the first step for the rehab project. Tilt-up was selected for its ability to cost-effectively combine the aesthetics of brick without efflorescence with the structural integrity of concrete. Perhaps the most spectacular feature of this building, the brick displayed creative and strongly defined detailing. The traditional brick color was employed to be reminiscent of the brickyard that was formerly located on the property. The entry utilized seven small panels to build columns and spandrels of which the four smallest panels are 20 sq. ft. each.
