Narrative

The City issued a Request for Qualifications (RFQ) in November 2019 to hire a consultant to provide design engineering services for the Phase 8 and 9 Sewerline Replacement Projects.  The City received statements of qualifications from four engineering firms and the selection committee selected MurraySmith to provide design engineering services for the Phase 8 and 9 Sewerline Replacement Projects.  The design engineering for the Phase 8 Sewerline Replacement Project is expected to be complete by December 2020, with construction expected to begin in Spring 2021.  In addition, a sewerline evaluation and preliminary alignment/design is included to determine the alignment of the sewerline that will be replaced as part of the Phase 9 Sewerline Replacement Project.  When services are required to design for the Phase 9 Sewerline Replacement Project, a separate scope and fee will be drafted in winter 2020 and submitted to City Council for approval.

 

In total, the design of Phase 8 and 9 Sewerline Replacement Projects will cover upgrades/replacements of portions of the City’s sewer network by replacing approximately up to 4,700 linear feet of existing sewerlines and associated appurtenances at various locations within the City.  The Phase 8 Sewerline Replacement Project will replace approximately 2,700 linear feet of sewermain. 

 

The selection of the sites was be determined using the data supplied in the 2013 Comprehensive Sewer System Plan dated August 2013, coordinating with upcoming road, water, and storm drain projects, and input from Public Works.  Projects for 2020 will focus on replacement of pipes that have minimal slopes and existing pipe damage/ degradation that cannot be addressed via trenchless construction methods.
