Watertown International Airport - Runway 28

Client: Watertown International Airport | Location: Watertown, NY | Completion Date: 2016 | Services Provided: Land Surveying


The Watertown International Airport received more than $3.5 million in federal funding to help finance a runway extension project at the airport. Funding was granted through the Federal Aviation Administration’s Airport Improvement Program. The extension allows for larger planes to land at the airport in the winter, as well as opening options for more air carriers and making the airport more accessible and attractive to travelers.

Aubertine and Currier completed a topographic survey, construction layout, and an as-built survey for the construction of approximately 1,000 feet of the new Runway 28 extension, and roughly 1,300 feet of parallel Taxiway A extension. The topographic survey was completed prior to construction and an existing conditions map was created to be used as a quantity basis during the construction process. All existing site improvements and topography were located within the project limits. These site improvements including but were not limited to, the existing runway and taxiway, roads, fences, and property line evidence. This information was used in the aid of construction layout and for calculating quantities of earth moved.

As part of the construction layout portion of the project, Aubertine and Currier laid out all of the new site improvements and grading for the project. The centerline and edge of the new runway and parallel taxiway extension were staked for the placement of the subgrade and for the onsite engineer to inspect the runway and taxiway construction. The subgrade course and each successive asphalt lift was surveyed and verified for grade prior to the next layer being laid down. This verification survey was performed to determine the thickness of each layer and to determine the vertical distance to the finish grade. A fill sheet and sketch was provided to the contractor after each lift of new pavement on the runway and taxiway extension. In addition to the runway and taxiway, the new access roads, clearing limits, drainage structures, fences and runway and taxiway lights were laid out for construction.

Upon conclusion of the construction, Aubertine and Currier performed an as-built survey of the Runway 28 project. The as-built survey map detailed all the new site improvements and updated grading. These new improvements included the new runway and parallel taxiway, access roads, fences, storm drainage and general site grading. The mapping was based upon existing site control for horizontal and vertical alignment and all mapping was shown at a 1 foot contour interval.

The field survey and mapping was performed under the direction of a New York State Licensed Professional Land Surveyor in accordance with The Code of Practice of The New York State Association of Professional Land Surveyors.
