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 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

We provided surveying services as a subcontractor on this large, ground-breaking project. It consists of ten interchanges, eighteen all-electronic toll collection “zones”, and it connects RTP to Holly Springs.
