Scope
This project included the restoration of a 120,000-sq.ft. parking garage structure and a resident plaza level with a pool, servicing a 300-unit apartment building. The structure required extensive repairs throughout, including slabs, steel beams and girder reinforcement to restore the structural capacity.
Approach
EDG was hired as design engineers and architects after initial cost estimates from less experienced firms, showed excess work and an over-estimated construction cost estimate. We were responsible for the concrete slab and steel framing rehabilitation, plaza level waterproofing (80,000 sq. ft. with topping slab construction), green roof installation, pool deck alterations, and ADA accessibility.
Impact
The repair work was completed on schedule and at 35% of the cost estimate provided by other consultants. We planned the work to be performed in eight phases so the garage could remain operational during construction. The 13,800-sq.ft. green roof transformed the previously unutilized plaza area into a beautifully landscaped amenity for building residents.
