Specifications include, but are not limited to: Conduct preliminary engineering and design engineering services for the proposed sanitary sewer forcemain reliever near Gateway Drive between Lift Station 5 and 7 The City’s wastewater system includes a number of lift stations that pump wastewater into a forcemain system. Lift stations 4, 5, 9, and 11 pump into a single 1.3 mile long section of forcemain that eventually connects to a larger forcemain system on Columbia Road. In the event there is a break in this 1.3 mile long forcemain, there is no alternate forcemain. The proposed reliever is intended to be used as an emergency forcemain to allow wastewater to continue to be pumped into the forcemain system should a break occur. The scope of work will include two phases with tasks accompanying those two phases. The first phase is reporting and includes: preliminary survey and drafting, hydraulic modeling for sizing, review right of way for acquisition, preliminary cost estimates, early coordination with NDDOT and BNSF. The second phase is the design phase and includes: ongoing communication with applicable City departments, Environmental and Historic Preservation Study, Benefit Cost Analysis, determination of alternate proposed routing options, coordination for various permits with NDDOT and BNSF, topography survey, final design and specifications, and cost estimates. All work shall be performed to City standards and procedures
