Raleigh-Durham International Airport Runway Replacement

Weston & Sampson provided LiDAR aerial surveying, terrestrial LiDAR HD scanning, topographical surveys, and Levels A and B subsurface utility engineering (SUE) services for the replacement of Runway 5L/23R, Raleigh-Durham International Airport (RDU)’s longest runway, and the parallel Taxiway B. The runway is needed to accommodate and attract new transcontinental and international flights.

The aerial mapping portion of the project involved collection of high-resolution aerial LiDAR imagery and creation of planimetric and topographic products in accordance with Federal Aviation Administration (FAA) AC-18B specs and airport GIS standards. The final products went through a rigorous QA/QC process, and accuracy analysis was performed on the LiDAR products.

Using both conventional topographic survey or bathymetric sounding, Weston & Sampson resurveyed areas that had been previously unattainable or had inaccurate aerial survey mapping data. Using our HD 3-D laser scanner, we performed a building information modeling (BIM) survey of the electrical Vault 2 interior in support of the electrical vault analysis/validation.

The team also acquired low-altitude helicopter LiDAR and provided a graphical Airport Layout Plan using imagery acquired from low-altitude fixed-wing aerial acquisition. The site was mapped at 1”=30’ scale accuracy.

Weston & Sampson wore ID badges and coordinated site access with the contractor and airport security personnel on a daily basis. Bathymetric surveying conducted at six ponds required authorization from airport fire and rescue.
