O&S performed a Structural Condition Assessment of all five garages at Richmond International Airport, which totaled 7,000 spaces and 2.2 million square feet of floor area. The field evaluation was completed in one week, and reports were completed in four weeks. The evaluation and reports were completed in 2018. Below are our findings on two of the five garages.
The Old North Garage is a 1,400-space, cast-in-place, post-tensioned concrete garage constructed in 1995. Our survey included 20% acoustic impact testing (chain dragging) of the supported floors, as well as full visual assessments of the soffits, vertical elements, and exterior elevations. We found that the garage was in good overall condition. We noted very few instances of concrete deterioration, of which none were of structural concern. We did observe that the waterproofing elements, sealant joints and waterproofing membranes, expired needed replacement.
The Rental Car Garage is a 600-space, precast concrete double tee and steel frame garage constructed in 1998. Our survey included 20% acoustic impact testing (chain dragging) of the supported floors and cast-in-place washes, as well as full visual assessments of the soffits, vertical elements, and exterior elevations. We found that the garage was in good overall condition. We noted very few instances of concrete deterioration, of which none were of structural concern. We did observe that the waterproofing elements, sealant joints and waterproofing membranes, expired needed replacement.
This vertical expansion project of the North Garage was needed to serve the growing airport passenger needs. The ramping system is a double helix arrangement utilizing one-way traffic and 70-degree parking. The structural system is cast-in-place, post-tensioned concrete to provide a large-span, open-feel parking and reduce long-term maintenance costs. The architecture includes precast architectural spandrel panels with brick inset and precast architectural column covers.
O&S was the prime designer for the vertical expansion of this facility. The existing facility was a 4-story, 7-bay, 2,600-space parking garage that was designed for two future floors of vertical expansion. O&S performed a structural feasibility analysis and determined that three additional floors could be constructed providing an additional 2,000 spaces. O&S’s structural responsibilities included code review, lateral load analysis, vertical load analysis, foundation design of an additional elevator and stair tower (helical anchor piles), foundation retaining wall design, column design, post-tensioned slab/beam/girder design, barrier cable, and mildly reinforced bridge/stair tower/crash walls design. O&S also performed architectural, parking, civil, mechanical, electrical, and plumbing engineering design services for this project. O&S was responsible for construction administration including submittal review, on-site representation, and request for information (RFI) coordination.
