XNA Parking Facility
The increase in airline passengers at the Northwest Arkansas Regional Airport led to the construction of a new parking structure in 2017. Our Oklahoma City BURG was the concrete contractor on 1,444 car parking garage and our scope included 1 level of slab on grade, 4 levels of structural slabs, post tensioned concrete slabs with barrier cables around the perimeter, as well as 3 sets of structural concrete stairs.
Our project site was adjacent to the active airport in the passenger terminal on the north side. It was imperative we didn’t block the access road that led into the terminal and we kept all debris off the tarmac. Besides good housekeeping, we utilized debris nets on handrails. There were other bordering parking lots to our site, so we utilized those as access areas to the job.
During our early planning stages, we identified a solution to impact our schedule to benefit our customer. We ran two deck crews simultaneously, which was great for the schedule, but it came with some extra logistical challenges. Detailed daily coordination was crucial to ensure deliveries were sent to the right crews and the formwork was going in proper sequence.
One unique feature was the 50-ft high bay roof that was positioned over the ramp, which ran on the outside of the garage. Typical height is 25 feet. Our team built up the scaffold to support this feature and it required a different shoring system. Furthermore, there were exposed crash walls, columns, and structural stairs that required a sunshade system, including barrier cable around the perimeter.
We wrapped up our portion of the project early, exceeding our client’s schedule by 3 months.
