TD&H Engineering designed the parking structure, retaining walls, Centennial Trail undercrossing structure, site layout, access roads, site drainage, water distribution, and sanitary sewer for the development of a mixed-use residential Planned Unit Development located on the south bank of the Spokane River.
Services relating to the parking structure included design and drafting of the structural components, waterproofing system, and subsurface water collection/disposal systems. The garage included approximately 200 stalls with limited access for emergency and moving vans through to adjacent residential structures. The system consisted of a precast concrete double-tee roof system, poured-in-place concrete foundation/retaining walls, and a concrete slab on grade floor. Plans included foundation and roof framing, sections, and details including a dimensional layout of parking areas with required signing and striping to allow for adequate parking and emergency access.
