Air Carrier Terminal Apron Replacement, Phases 1-3
Greenville-Spartanburg International Airport, Greer, SC
Cost $17.9M
Project Description
This project comprised complete air carrier terminal apron replacement and strengthening and was divided into three phases to coincide with available federal and local funding. Phase 1 included replacement of over 1,700 feet of existing cast iron trench drain with a precast slotted concrete drain. Phases 2 and 3 included complete replacement of the PCC pavement, base and subbase courses.
Project Highlights
-
Designed the concrete slabs with open drainage slots in the top
- 144 precast concrete panels were custom designed and manufactured to match the existing concrete apron joint pattern.
- The slabs were labeled and delivered to the job site in sequence and set on the existing prepared surface and tailored-cut trench walls
- Phase 2 included nearly 25,000 SY of 17” P-501 PCC pavement
- Phase 3 included 29,000 SY of 17” PCC P-501 pavement
- Phases 2 and 3 also included 9,000 SY of new apron widening to allow for larger separation of GSE equipment
- Connector Taxiways L2 and L3 to the terminal apron were also widened and fillets upgraded to facilitate larger aircraft and their turning radii.
- Due to local subgrade conditions, a new underdrain system was constructed under the new PCC surface
-
Analyzed gate utilizations
- Repainted each of the aircraft lead in lines with varying nose wheel markings to maximize the utility of each gate for various aircraft
