The area of work involved approximately 116,000 square feet of the top (Fourth) level of this deck. This also included the two ramps up to this level and a small portion of the third levels at the base of each ramp. In addition, we were to design a way to improve the top-level drainage. We performed a topographic survey of the parking deck top level and inspected it during rain events. After reviewing this information, we considered improving the deck slope in some areas, but ultimately decided against this in favor of installing additional localized deck drains to remove ponded water from isolated areas of the parking deck. The review of the existing structure was performed to ensure new drains would not compromise the existing post-tensioned concrete structure.
