Dulles International Airport Traffic Control Tower

AMT provided civil engineering services in support of the New Airport Traffic Control Tower (ATCT). Services include the design of over 2,500 LF of Domestic Water Line extension, over 1,000 LF of Dedicated Fire Service (DFS), over 1,500 LF of gravity sanitary sewer line, over 2,500 LF of Gas service line, site grading plans designed for both the existing conditions and future Tier 3 planned conditions, stormwater pollution prevention plans, storm drainage plans, parking lot and entrance roadway, AOA fence and construction phasing plans. Sanitary sewer plans were processed through and permit was obtained from Virginia Department of Environmental Quality (VDEQ). Plans and computations for the domestic water were provided for MWAA in order to obtain permit from VDH.

Studies were prepared to determine alternatives for how the ATCT would connect into the future Airport sanitary sewer outfall system. The ATCT site design was coordinated with future Tier 3 and associated aprons design information to minimize future conflicts.

In addition, AMT designed the Power and Communication Duct Banks to service the ATCT and FAA facilities. This included over 36,000 LF of 2-way through 12-way duct bank located throughout the Airport Area. Plans, profiles and details were developed. Existing duct bank manholes were field located and evaluated to determine their condition and assess the availability of spare conduits. Trenchless methods were used for crossings under runways and taxiways and careful planning was provided to ensure coordination with operating airfields. Detailed maintenance of traffic and phasing plans and schedules, were developed for work within, or in proximity to, OFA and RSA. Taxiway closures or work hour restrictions were determined.

Standard civil specifications were developed using a MASTERSPEC based system with typical MWAA specification sections.
