Sparc Apartments consists of five independent multi-family apartment buildings over a combined concrete podium with subterranean parking at the Spring District’s southwest corner.
Building A is five levels of wood-framed structure over a one-level concrete podium. Building B is seven levels of light gauge bearing walls with concrete on metal deck floors over a two-level concrete podium. Building C and D are four levels of wood-framed structure over a two-level and a one-level concrete podium respectively. Building E is three levels of wood-framed structure.
The use of light gauge construction at Building B proved extremely efficient. Unlike wood, this high quality system is fire resistant and free of vertical shrinkage. Further, by using concrete-filled metal jumbo deck, floor spans exceeding twenty feet were made possible and the need for sub-framing was completely eliminated. This resulted in reduced floor-to-floor height.
The Spring District is a 36-acre mixed-use urban development at the intersection of SR-520 and I-405 in Bellevue, Washington. The emerging neighborhood will make up 16 full city blocks and add over 5.3 million square feet of transit-oriented communities.
