Square Feet: 36,000
Construction Materials: Structural Steel, Pre-cast Concrete, Composite Metal Deck
The existing site had been constructed in 2005. The original project included the construction of two infiltration basins on the north side of the site to treat the stormwater runoff. The new addition and parking required the relocation/redesign of the basins. The new stormwater design had to incorporate the existing level of treatment provided in the existing basins and the additional treatment needed for the additional impervious surfaces. BKBM accomplished this by designing three new basins consisting of a new infiltration basin, a new filtration basin, and a rate control dry pond. The change to a filter basin was needed due to clay soils on the west and northwest portion of the site. The new infiltration pond was design to infiltrate the 1.5-inch storm event from the entire site. This volume satisfied the existing treatment volume and the new treatment volume requirements.
Structural design included engineering for an approximate 36,000 square foot two-story addition. The structural framing consisted of composite steel beam floor framing and steel bar joist roof framing suppoorted by steel beams and columns. Lateral resistance was provided by a combination of existing and new precast perimeter walls.
