The RDU Taxiway B Rehabilitation project was undertaken to entirely demolish and replace the northern half of Taxiway B and adjacent holding pad, with thirty-foot wide asphalt shoulders added to replace the grass shoulders.
Surveying services included construction layout/staking and construction verification surveys, along with the horizontal and vertical control surveys needed to support the contracted services.
Layout/staking services were provided for the LOD, electrical fixtures (taxiway lights, edge lights, wig-wag lights, signs), taxiway markings, stormwater system changes, taxiway pavement, and shoulder pavement. Grade verification services were provided for the subgrade, base/subbase, and pavement of the taxiway, holding pad, and shoulders. Layout and grade verification services were performed in accordance with the governing FAA specifications. Distinguishing characteristics of the project included:
- Federal (DoHS/FAA) security regulations in effect for the project site.
- Project site embedded in an active international airport.
- Nighttime work necessary for areas inaccessible during the day.
- Sustained 6-day, and often 7-day, working weeks.
- High positional accuracy requirements (needed to meet FAA positional tolerances)
- High data volumes and frequent reporting requirements
- Very close collaboration between field and office staff
