SUBJECT:
A Resolution allowing the Director of Purchasing to approve Change Order 1 to the Contract with Brandt Excavating for the Morningside Drive Water Main Replacement Project.
PURPOSE:
In order to make modifications to an existing contract, City Council approval is required. Approval of Change Order 1 (attached as Exhibit A) will modify the existing Contract with Brandt Excavating to eliminate a section of water main from Morningside Drive to Sixth Avenue and replace it with a similar length of water main replacement on Root Street from Galena Boulevard to Downer Place. The Morningside Drive water main is located in Ward 3 and the Root Street water main is located in Ward 2. See the attached Exhibits B and C for the project locations.
BACKGROUND:
In an effort to improve the City water main system, various sections of water main are replaced annually. When determining which sections to replace, engineering staff evaluates break history, water quality, fire flow, roadway resurfacing schedules and various other factors. The Morningside Drive Water Main Replacement Project included new water main on Morningside Drive from Smith Boulevard to the west end and a section of water main from Morningside Drive to Sixth Avenue. While the main on Morningside Drive has broken frequently in recent years, the section from Morningside Drive to Sixth Avenue has no history of breaks but was going to be replaced pre-emptively under the assumption that it was installed at approximately the same time as the main on Morningside. While it is possible that this main may begin to break in the future, engineering staff recommends that these funds be utilized to replace a different section of water main that has had a recent increase in breaks. The water main on Root Street from Downer Place to Galena Boulevard has broken three times this summer and is in need of imm...
