BACKGROUND
background
Both the Plaza parking deck and the Truist (formerly BB&T) parking deck are at a point in their lifecycle when refurbishment is needed. Currently we are experiencing several issues related to age and waterproofing failures that will begin to shorten the life of the deck structures. Water intrusion is allowing water to migrate through the deck structures and begin to corrode the reinforcing steel in the concrete members. Water intrusion also causes the concrete to spall, or flake off, because of cracks developed from the intrusion. The impacts of the water intrusion are visibly evident as leaks in the decks during rain events, which can damage automotive finishes and cause physical damage to the cars themselves. The long-term consequences of water intrusion is a reduction in the life of the parking structure due to different corrosion mechanisms that attack the steel reinforcing and concrete that support the decks and plaza. It is important that the County move ahead with waterproofing and structural refurbishment at this point in the structure's lifecycle to preserve the maximum potential life for the two parking decks.
Also as part of this design, the plaza that is above the parking deck will be re-designed. The construction effort will require extensive work in the plaza which will provide an opportunity to provide a modernized landscape design for the plaza. Landscape design options will be developed as part of this design contract.
A request for qualifications was used to solicit qualification packages from structural engineering firms who have experience in parking deck refurbishments. The County received four qualification packages. Two firms were selected for in-person interviews based on the evaluation committee's scoring of the qualification packages. WG...
