LDA Engineering provided design services for expansion of an existing industrial building to include warehouse space. Several challenges were involved in this project including construction in a flood plain, wetlands mitigation, and construction of access for tractor trailer trucks over unfavorable terrain. LDA also modified an existing hydraulic model of an adjacent stream to determine if the new building would adversely impact floodwater elevations upstream of the development. This included a “no-rise” certification as required by FEMA, and a bypass structure was designed in the existing stream to divert water into a wetlands area during high flows.
LDA provided design for the facilities including structural, mechanical, electrical, and plumbing. Key aspects involved a dock facility and energy efficient design including economizer ventilation, radiant heating, and lighting control. The building foundation design presented a unique challenge. The site where the building was to be constructed had previously been filled with debris and was underlain by soft, mucky in-situ sols. LDA was able to design a pile foundation to support the building and associated loads, while still allow the client to utilize the space.
Additionally, a hydraulic analysis and design services were performed for the construction of a fork lift bridge across an unnamed tributary to Turkey Creek. The bridge had an eight feet vertical under-clearance, the double span bridge was comprised of steel grinders with a concrete slab deck. There was one intermediate pier, and a hydraulic analysis was required in order to verify “no-rise” in the water surface profile due to the construction of the intermediate pier within the floodway.
