Commercial | JACOBSEN CONSTRUCTION CO. – WCF HEADQUARTERS Building With Synergy THE PLANS FOR THE WCF HEADQUARTERS FEATURE INNOVATIVE SEISMIC DESIGN. BY GENEVIEVE DIESING uilding the Workers Compensation Fund (WCF) Headquarters building in Salt Lake City is a project that would challenge most contractors. When complete in July 2010, the structure will be six stories, 183,378 square feet, built to LEED gold standards and will be one of the most seismically sound buildings in Salt Lake City. Jacobsen Construction Co. accepted these challenges with open arms. As a construction manager for the job, the Salt Lake City-based company participated early in the design, which saved about six months of the schedule, Project Manager Heather Talenah says. “It takes more detailed engineering and review and inspection on the quality control level for a project like this,” Talenah explains. She says Jacobsen’s commitment to quality and safety made it best for the job, as well as its ability to partner with project owners and understand their needs. In this case, the WCF wanted a building that could be accessed immediately after an earthquake – it is located right along the Wasatch fault line – requiring a highly involved seismic design. The design complies with the retrofit code ASCE 41, which provides the technical basis for a higher performance level than the standard seismic code. “At the end of the day, the lateral forces were three-and-a-half times higher than what a typical code would give us,” says Paul McMullin, who represents structural engineer Dunn Associates on the project. and subcontractors »Jacobsen’s employees on the Workers truly worked together Compensation Fund Headquarters. Innovative Technology To fulfill these requirements, the construction team utilized Sideplate technology, a more robust connection than the typical beam connection. Although this connection is proprietary and came with a fee of about $100,000, WCF wanted it because of its structural reliability, McMullin notes. “It isn’t often an owner knows enough about structural engineering to know what kind of connection they want used,” McMullin says. Additionally, “the owner wanted as much progressive collapse protection as they could get.” The Sideplate technology and perimeter frames make the building progressive collapse resistant, meeting an unofficial desire to protect the building from a blast event.

It did this by using interior concrete walls in addition to a perimeter moment frame. This reduced the lateral force in the frames. With less force in the steel frames, the company was able to use 400-pound-per-foot steel columns instead of 800-pound-per-foot steel. This saved a significant amount of money and also reduced the lead-time, since 800-poundper-foot steel isn’t available domestically and could have taken up to six months or longer to procure from overseas, McMullin notes. The WCF Headquarters building’s innovative qualities don’t end with unique seismic “We really built a top-notch, class-A office building.” –Heather Talenah, project manager nology also increases the joint stiffness of the beam column interfaces, thereby reducing tonnage, McMullin says. Dunn and Jacobsen also saved money and time on steel cost and delivery by reducing the CONSTRUCTION-TODAY.COM OCTOBER 2009
