structures, cast-in-place structures and the precast truss system, PCL Construction selected Kerkstra’s precast system. Known as an ER-POST system, the patented precast option was designed by engineering firm Ericksen Roed & Associates, based in St. Paul, Minn., and provided a durable, sound alternative with a lower price tag and much faster timetable. First created for a multistory developer in the Minneapolis area, the ER-POST system provided a solution for retail on the main level, parking below and living or office space above with no column penetrations. In that application, the setup proved itself to be cost effective because of its speed and at-plant cost savings. The system utilizes precast, prestressed concrete trusses that support two levels simultaneously. The trusses span approximately 60 feet and are spaced to maximize column spacing. The alternate levels are wide open with no structural elements, allowing complete flexibility in layout of interior walls and partitions. Parking levels with column-free spaces result in approximately 15 percent increased capacity. High fire ratings and sound transmission also are inherent in this system. Since that original project, four others have used the patented truss system. Three more are currently underway and another 10 are in the design phase, according to Michael DeSutter, partner and vice president at Ericksen Roed, an engineering firm that got involved in the Turtle Creek project after conferring with the project architect, Walsh Bishop. “We’ve worked with Walsh Bishop for several years now,” says JULY/AUGUST 2008 Turtle Creek Casino, conceptualized in an artist’s rendering above and under construction at left, uses precast concrete extensively. | PRECAST SOLUTIONS 11
