Little Diversified Architectural Consulting
A unique two phased project, the first phase consisted of retro-fitting of a 5-level existing parking deck (approx. 500,000 sq. ft.) which included slab on grade removal, excavation, new foundations, and slab pour-back. New shear walls and columns were extended from foundations to top of existing garage.
The second phase of the project consisted of a four-level vertical expansion on-top of the existing parking deck adding approximately 290,000 sq. ft. to the deck. The scope of work included post-tensioned elevated decks, columns, crash walls, and barrier cables. Two 500-series tower cranes were used to support hoisting activities.
This new parking deck serves the university’s new South Village, which features student housing and a new dining hall, and replaced the surface lots that were lost due to adjacent construction projects. Construction of the deck required close coordination and scheduling with nearby projects and specifically the Regional Utility Plant 4 construction, which shares common structural components. The construction schedule was closely managed, as the project was critical to supporting the parking needs in the South Village development plan.
The structure consists of cast-in-place concrete columns, post tensioned beams, and slabs on form deck, while the exterior walls feature precast panels with thin brick. The deck also includes two structural precast stair towers, and elevator tower, and canopies.
A comprehensive site work package is part of the project and included demolition of the existing parking lot on the project site and extensive excavation, along with utilities, paving, segmental retaining walls, and landscaping.
