Giuliani is part of the Hensel Phelps design/build team chosen by Metropolitan Washington Airports Authority to design and build the Silver Line Rail Yard at Washington Dulles International Airport. Giuliani will be providing architectural design services and Building Information Modeling services to Hensel Phelps. As part of the agreement, Giuliani will also staff the design/build office with a project manager to collaborate with the design/build team on a daily basis.
Project Description: This project includes 5 major buildings and several outbuildings and trackwork associated with maintenance of the 23 mile extension of Washington DC’s Metrorail system.
The largest building (211,000 SF) in the complex is the Railcar Service and Inspection Facility (SIB) which includes a 49,720 SF Warehouse Facility (WHB) and the general rail yard operations tower. This facility supports all aspects of regular maintenance of revenue rail cars, including washing of vehicle undercarriages, interior cleaning, wheel truing, general maintenance of railcars, repair and re-fabrication of running gear, air conditioning and electronic train control systems. Shop areas include in ground lifts that can raise entire married pair vehicles, with or without trucks. 17,000 SF of state of the art class A office space supports this operation. The warehouse facility provides shipping receiving and storage facilities to support the SIB operation.
The second maintenance facility is the 68,000 SF Maintenance of Way building (MWB) which houses shop, storage and office support space to facilitate maintenance and repair of all heavy rolling stock that maintains the track and right of way for the system. Two of the projects five overhead cranes support the main shop area.
The third largest facility is the 34,590 Transportation/Police Building which include facilities for support of all Driver related functions and Metro Police activities.
The project also includes a 14,750 SF Train Wash Facility (TWF) that accommodates automated pre-wash, washing and drying of
full married pairs of revenue railcars. All cleaning solutions are recycled.
The final significant building is the 2,100 SF Vehicle Storage Facility (VSF) which can accommodate four service vehicles.
A significant portion of the site is given over to at grade rail tracks and supporting infrastructure necessary to provide access to the various facilities and includes rail car storage, exterior railcar maintenance and non-railcar access to maintenance facilities.
Additional support systems include communications infrastructure, traction power substations, train control systems & equipment, building automation and SCADA monitoring.
Also included on the project campus are roadway improvements to accommodate highway vehicle access to all facilities, drainage and stormwater management facilities as well as site utilities to support this major industrial facility.
The exterior character of all buildings consists of light and medium gray insulated precast concrete wall panels with dark anodized storefront windows and matching sunshades, personnel and train access doors, door canopies and mechanical louvers. Interior spaces are detailed commensurate with project requirements and include heavy shop areas, a clean room, a train truck washing area, a paint booth, specialized shop & storage areas and administrative office facilities. All facilities conform to applicable national, state and local building codes and standards as well as MWAA and WMATA (Metro) standards.
Special equipment includes five overhead bridge cranes; a dozen train car lifts, a paint booth and a myriad of specialized industrial equipment to accommodate all required maintenance of rail cars and track systems.
The three main building are expected to receive LEED Silvercertification.
