Design Services for Washington-Area Airports

JMT provided on-call engineering services over a multi-year period for a wide variety of civil design tasks including the following:

Runway 19 Approach End Safety Area Improvements at Ronald Reagan Washington National Airport (DCA) – This task included grading improvements to the existing 500-foot by 700-foot runway safety area for Runway 19 to comply with the federally-mandated RSA compliance requirements. The design included re-grading of the RSA to meet FAA criteria, relocation of several existing utilities, modifications to the Perimeter Intruder Detection System (PIDS), and the design of a stone revetment in the Potomac River. Since RWY 1-19 is the primary runway at DCA, the project was designed to be constructed during runway closures, which were planned to occur overnight. The contractor also had to meet FAA grading requirements to maintain acceptable slopes during construction.

Washington Dulles International Airport (IAD) Pad B Enhancements – This assignment was subdivided into three tasks identified as follows: IA 1001 sanitary sewer extension; IA1005 domestic water line under Taxiways Y & Z; and IA 1006 site work and utilities for glycol tanks and airline offices. Design included a temporary trailer complex for airline personnel; new foundations for two 55-foot diameter, 15-foot high glycol storage tanks; new controls systems to coordinate existing glycol pumps, new sanitary sewer pumps and the existing stallion branch sanitary sewer pumps. Assignment also included the pavement joint evaluation of hold apron.

IAD Fifth Runway Tree Clearing, Phases 3 and 4 – These two assignments were in support of MWAA’s environmental impact statement and record of decision requirements that calls for the airport to take major steps toward implementation of the fifth runway. The two areas cleared are directly over the location of the proposed fifth runway for IAD.

IAD Glycol Runoff Enhancements – Fast-track design of new weir structure to collect low-flow, high-concentrated glycol runoff to be pumped to frac tanks and the renovation of two existing manholes adjacent to hold Apron 30 to allow the installation of pumps to collect glycol runoff.

IAD Live Fire Arms Outdoor Shooting Range & Training Center – JMT developed several conceptual site plans, including outdoor pistol and rifle ranges, various sized training facilities, and associated vehicle parking.
