Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: Bob Murray, Project Engineer Shawn Kohtz, City Engineer
SUBJECT: Davis Lane Lift Station and Norton Sewer Project – Fourth Amendment.
MEETING DATE: October 6th, 2020
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Approve and authorize City Manager to sign the Fourth Amendment with HDR Engineering, Inc.
BACKGROUND: Attached is a copy of the partially executed Fourth Amendment with HDR Engineering, Inc. for the Davis Lane Lift Station and Norton Sewer Project. The document is in
the City’s standard format.
The developer of the Northwest Crossing subdivision NWX, LLC has requested that the new sewer main between Equestrian and Baxter be installed deeper than it is currently designed and was bid. This will allow them to replace the sewer main along Baxter deeper than it is now which in turn will allow them to serve more of their property by gravity flow. This amendment
is for the cost of the redesign for the deeper installation between Equestrian and Baxter. The
developer will be reimbursing the City for the cost of this amendment and also for the additional cost of the deeper installation which will be processed in a future change order from the contractor.
UNRESOLVED ISSUES: None
ALTERNATIVES: As suggested by the City Commission
FISCAL EFFECTS: $6,395.00 to be reimbursed by NWX, LLC
Attachments: Fourth Amendment

City of Bozeman to permit the redesigned plans, if necessary. This shall include minor revisions to the engineering report, if required. This item shall not include significant modifications to DEQ permitting material or preparation of deviations.
