Bismarck Public Works requests written qualification proposals from professional engineering firms for the engineering services required to complete the following:

Evaluation of the Hay Creek Sanitary Sewer Interceptor and Lift Station

The Hay Creek Interceptor was constructed in the Hay Creek valley in 1975 to provide service capacity to areas in the north, northeast, east and southeast areas of Bismarck. The service area contains the majority of the area for future growth. The interceptor is subject to infiltration and inflow (I/I) that impacts its capacity.  The Hay Creek Lift Station was built in 1975. The evaluation will include systematic assessment of the condition and future capabilities of the interceptor sewer and lift station to meet future service needs along with the development of a strategic plan for sewer system improvements including I/I correction, relief sewers and lift station improvements to assure the ability to provide the capacity and reliability for continuous long term reliable operation.

 Interceptor Sewer Evaluation – Complete by September 2018

  • Evaluate and identify the sanitary sewer collection system’s existing capacity using the data in GIS, evaluate response to wet weather conditions and areas of concern to handle current demands as well as future wastewater flows based upon the 2014 Growth Management Plan, as amended.
    • Develop a hydraulic sanitary sewer model for the Hay Creek service area.
    • Perform manhole inspections on key trunk laterals to verify pipe and flow conditions and possible flow meter locations.
    • Identify key locations to perform flow monitoring to be used to calibrate and validate the hydraulic modeling efforts.
    • Evaluate the pipe capacity on the trunk laterals under a range of flow conditions to determine collection system response and pipe capacity under current and future base flow and storm event conditions.
    • Provide recommendations for capital improvements required to meet present and future sanitary sewer capacity needs.
  • Based on the hydraulic model, develop an I/I program approach designed to reduce excess sewer flows due to I/I entering the collection system in areas that restrict needed capacity. Evaluate the cost effectiveness of I/I removal versus the construction of additional capacity.

 Phase 1 - Asset Inventory and Assessment of Lift Station – Complete by September 2018

  • Complete structural and architectural evaluation of the existing station, including structural integrity, interior and exterior finishes, doors, windows, roofing, coatings, flooring, hatches, insulation, landscaping and drainage, etc.
  • Physical condition assessment and hydraulic analysis of pumping system, including piping, valves, force mains, wet well, and pumps.
  • Electrical analysis, including utility feeds, transformers, station electrical, pump wiring, back up electrical system, lighting, and security.
  • Control system analysis, including level controls, alarms, panel information, station telemetry and SCADA system.
  • HVAC analysis for adequacy, efficiency, reliability and safety. 
  • Evaluate station operation at average and peak flows, maintenance concerns, pump efficiency and reliability and safety issues for the station and its equipment, including: physical condition and remaining useful life; current performance and use; ultimate capacity and demand limitations; and operation and maintenance concerns

Phase 2 - Evaluation and Recommendations of Lift Station – Complete by March 2019

Based on Phase 1 and Sewer Evaluation flow projections:

  • Predict future service demands based upon the growth in the sewer service area.
  • Predict how and when the station will fail to meet future needs.
  • Analyze alternative operations, maintenance and construction options.
  • Review and rank operations, maintenance, rehabilitation, replacement and new construction options on a cost effectiveness basis.
  • Provide recommendations for improvements taking into account potential phasing of the work for operational concerns, constructability, and financing considerations.
  • Prepare and present a final report detailing conclusions and recommendations on preferred alternatives for increasing the capacity, reliability, efficiency, safety, security and longevity of all aspects of the lift station. The report will contain preliminary design layouts and cost estimates for the recommended alternatives for upgrading the station.

The engineering selection process will be completed in accordance with established City of Bismarck procedures. Written proposals shall address the firm’s ability, and specifically the project team’s ability, to perform the necessary services in the allotted time. The primary consideration items will be, but not limited to, the firm’s:

Technical Capabilities
1.Experience and Performance Records
2.Understanding of Project and Proposed Work Approach
3.Knowledge of Regulations and Local Conditions
4.Project Personnel Assignments and Qualifications
5.Ability to Respond in a Timely Manner

Special Requirements:
The selection of the firms to be interviewed will be based on an evaluation of the written proposals. A selection committee will interview the selected firms and recommend a single firm for approval by the Board of City Commissioners. A detailed scope of work will be developed and price will be negotiated with the successful firm. An engineering agreement will be executed with a single firm. Approved sub-agreements for minor portions of the work will be permitted. It is expected that a firm that satisfactorily completes the lift station evaluation and planning portion of this project will be selected to design the recommended improvements; however, the City retains the right to select another firm to complete the design for any reason. Selection of firms for any follow up work related to capital improvements to the sewer collection system will be a separate process.

Written proposals from qualified consultants will be accepted until 5:00 p.m. CST on January 22, 2018.

Submit eight (8) copies of proposals to:

Michelle Klose, P.E.
Director of Utility Operations
City of Bismarck
