Design engineering services for sewer improvement projects located throughout Chicago. Work includes data collec-tion and initial assessments, coordination of survey and geotechnical engineering, utility coordination, sewer align-ments and profiles, structural design, compliance with IEPA water sewer separation requirements, cross sec-tions/typical sections, traffic control and detours, surface drainage design, OUC submittals and approvals, and permitting.
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 provided a PER and Design to replace a trickling filter Wastewater Treatment Plant (WWTP) with a new 200,000 gpd Moving Bed Biological Reactor (MBBR) treatment plant installed inside of the existing concrete treatment tank. Design elements included rehabilitation of the existing influent pump station and existing operations building, a standby generator, and demolition of existing WWTP components. Additional services included surveying and civil design.
Bowman was selected to perform utility engineering services for various water and wastewater systems. Bowman is responsible for attending various meetings with County staff and Supervisors, regulatory officials and representatives from the funding agencies in pursuit of financing for the below identified projects, as well as attending public meetings.
Bowman provided planning, engineering, surveying, landscape architecture, and environmental consulting services within the 120-acre Lee District Park as part of the Family Recreation Area Spray Park and Accessible Tree House and Chessie Trail development. The accessible trails and tree house project had significant topographic and tree preservation challenges.
