The Craige Parking Deck Expansion was a two-phased project Donley’s worked on at the University of North Carolina Chapel Hill campus. The first phase consisted of retro-fitting a 5-level existing parking deck (approx. 500,000 SF), 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. This added approximately 290,000 SF 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.
