On-Call Services

Under this five-year term contract, SJH provided design services as a DBE subconsultant on the GFP team on an as-needed basis to support WMATA’s capital improvements program. Services included the design of new facilities as well as upgrades and expansions.

Condition Survey of Four Multi-Level Parking Garages – VA, MD SJH provided an Assistant Team Leader and participated in the structural condition survey inspection of four (4) multi-level parking garages. These inspections focused on all structural aspects of the buildings. A condition survey report identifying deteriorations and recommendations for repairs was prepared at the end of the field survey and submitted to WMATA. Our team member also provided AutoCAD support in the development of the Condition Survey Report. Through this project, SJH became very familiar with WMATA CAD standards and report preparation guidelines.

Dry Fire Standpipe System Replacements – DC, MD, and VA SJH provided inspection and design services for the replacement of 19 dry standpipe fire protection systems in the tunnels, vent shafts, fan shafts, and emergency exit shafts throughout the Metrorail system. SJH was responsible for the fire standpipe replacements on Routes A, B, C, and F. Initial field investigations were completed during non-revenue hours to determine site conditions. The designs included replacement of the existing dry standpipe risers associated with the wet standpipe fire protection systems of the Metrorail stations, from the fire department Siamese connection at street level down to the wet standpipe system within the station. The complete design package included drawings, pressure drop and fill-time calculations, and material specifications. Drawings were developed to WMATA CAD standards, and the system designs satisfied the requirement of a 100 PSI maximum pressure drop from the Siamese connection to the last Angle Hose Valve on the longest line, with a fill time under 10 minutes.

Final Design of the 7000 Series Railcar HVAC Unit Repair and Overhaul Shop – Greenbelt Maintenance Facility, MD This two-story steel-framed building was intended for the repair of HVAC equipment from rail cars. SJH was responsible for the structural design of the steel frame of the building, including all supports for cladding and other elements; steel supports for cranes and hoisting equipment; structural supports for the elevator shaft; stairs; supports for roller doors at the loading area; the loading bay and platform; and structural supports for the HVAC workstations and platforms. Due to the anticipated weight of the heavy equipment, some floor areas were expected to require redesign to support the additional loads.
