Washington Dulles International Airport - Central Utility Plant
Washington, DC
WMC assisted in providing site planning, engineering design and construction plans for the expansion of the central utility plant. The utility plant expansion was necessary to meet the needs of the expanded terminal facilities and increased usage of the airport facility. Utilizing passenger travel forecasts, the extent of utility expansion was modeled to estimate future load requirements for the high temperature hot water and new super-chilled water service systems. Feasibility studies were undertaken to determine alternative routing for utility service to existing and future facilities and an evaluation was made of the central plant facility. Site plans and engineering designs were also prepared for the ultimate circulation, parking and access needs of the utility plant. The associated expansion of the central plant facilities was evaluated to determine site and operational constraints. In addition, WMC participated in the preparation of construction phasing plans and value engineering evaluations of the various projects involved in the airport expansion program to determine the impacts of each construction phase on the central utility plant modification.

Washington Dulles International Airport - Utilities Relocation
Washington, DC
WMC key staff prepared site plans, engineering design and construction drawings for the complete relocation of existing utilities in order to allow a series of airport expansion projects. Multiple options for relocation of existing utilities and provision of new facilities were studied to determine the best alignment for airport operations while also providing economically viable solutions.
An engineering plan was produced that allowed continuous utility service and uninterrupted access to the terminal for the entire construction period. Complete relocation of existing utilities network necessitated extensive research of utility records and multiple test-pits to prepare an updated utility base map to plan and layout their new alignment.

DC Water – Division C – CSO 019 Overflow and Diversion Structures
Washington, DC
WMC is part of the architectural/engineering team slated to provide design and related services to be performed for Division C – CSO 019 Overflow and Diversion Structures. DC Water is implementing its Long Term Control Plan (LTCP) to control CSOs to the Anacostia and Potomac Rivers and Rock Creek.
The purpose of the overflow structure is to provide for discharges from the combined sewer system to the Anacostia River when conditions exceed the capacity of the CSO tunnel system.

DC Water – Anacostia River Combined Sewer Overflow (CSO) Control Projects Division
E – M Street Diversion Sewer (CSOs 015, 016 and 017)
Washington, DC
WMC is part of the design team for surveying services relating to DC Water’s Division E – M Street Diversion Sewer (CSOs 015, 016 And 017). This project is intended to address Consent Decree requirements to control overflows from CSO 015 and to consolidate CSOs 016 and 017. Overflows will be intercepted at the existing combined sewers by constructing diversion chambers and diverted flows will be conveyed to the Anacostia River Tunnel (ART) by a series of diversion sewers and microtunnels constructed under M Street, SE. Diversion chambers will be constructed under M Street to intercept CSO’s 015, 016 and 017 at 9th, 12th, and 14th Streets SE, respectively. A 36” diameter microtunnel will convey flow from CSO 015 to CSO 016, and a 96”
microtunnel will convey flow from CSO 016 to CSO 017. The combined flow diverted from CSOs 015, 016, and 017 will be delivered to the ART via a vortex drop and deaeration facility to be constructed near the intersection of Water and M Streets SE. The vortex drop facility, deaeration tunnel, and final connections from the M Street Diversion Sewer to the ART are part of future work to be designed by others.

DC Water – Main Process Train
Washington, DC
WMC is providing civil and surveying services as part of the design build team for the construction of the Biosolids Wastewater Management Plan – Main Process Trail at the Blue Plans site. The project will prepare sludge to undergo a thermal hydrolysis process in which gas will be generated to provide power for plant services utilizing the Cambi System. The specific scope of services includes preparing site plans in conjunction with the team in a fast paced environment addressing issues relative to the design, review, and construction, all simultaneously. Illustrating all information from DC Water including documentation from
existing and current field surveys, including benchmark, existing survey control, and survey control point locations. Civil drawings are being designed in accordance with a preliminary engineering report in support of the design-build team to achieve all of the requirements for the various disciplines in addition to the requisite stormwater management, erosion control, grading and extensive utilities on the site.
