Bowman staff has provided design engineering services for more than 200 sewer improvements on a task order basis throughout the City of Chicago. Sewer sizes vary from small diameter to 15-ft by 12-ft monolithic concrete sewers.

Bowman prepared a traffic impact analysis, travel demand forecasting, traffic signal warrant analysis, preliminary traffic signal design plan, and provided public involvement support for the 4,000 LF extension of Claiborne Parkway in Loudoun County. The project was locally administered by the County’s Office of Transportation Services, and Bowman also provided survey, environmental permitting services, and roadway and drainage design for the entire project.

Bowman provided its full scope planning, professional design, and construction management services to support the development of a charter school. The project required complex design aspects to accommodate the main facility and its ancillary support buildings and areas. The team also coordinated with local authorities for the expansion of public road and utility infrastructure to connect to the project.

Bowman provided a multi-faceted planning, analysis, and design scheme to redevelop a declining 200,000 sq. ft. community shopping center. The team was challenged to create a more pedestrian friendly design all while providing adequate vehicle site access. Bowman also provided the Site Design, Surveying, and Local, County and State Permitting for the project.

A new leach pad is being developed to meet the needs of a new pit. A major earthwork project was undertaken to link the existing conveyor system to the new leach pad. As part of this project, Bowman provided temporary traffic control and temporary road designs as well as engineered drawings, specifications, construction scopes of work, and bid packages for the earthwork and new traffic underpass.

Bowman developed a water distribution plan to provide potable and construction water to thhis project. This included the design of wells, impoundments, booster stations, overland pipelines and storage facilities. The first stage of this system currently operates at 650 psi and transports water over 2 miles.

Bowman designed three stormwater diversions to protect a leach pad. These diversions required the engineering design of several structures including channels, levees, energy dissipation structures and box culverts. In conjunction with these designs, Bowman developed method specifications for compaction and a design for soil cement that utilized the material sourced from the channel excavation.

Bowman partnered with English Construction for this Design-Build project for a central wastewater collection, treatment and disposal system to serve the service districts of Catlett and Calverton. The project includes a new collection system consisting of individual Septic Tank Effluent Pump (STEP) systems that transfer wastewater to a 80,000 gpd central wastewater treatment plant utilizing an Integrated Fixed Film Activated Sludge (FAS) technology. Effluent will be disposed of through the use of subsurface drip irrigation drain fields.

Bowman provided a detailed topographic survey and preliminary engineering services to facilitate initial discussions with Calvert County officials and included a concept plan to illustrate the improvements relating to the proposed solar panels.

Bowman prepared ALTA/ACSM surveys, detailed topographic survey including necessary road frontage surveying. Approximately 25 acres of topography were required on the Bradley farm site, and approximately 35 acres of topography were required on the Carter farm site, as a minimum 75-foot overlap around the perimeter.
