Resolution 4733 Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Bob Murray, Project Engineer Rick Hixson, City Engineer SUBJECT: Resolution 4733 authorizing Change Order No. 1 to the 2016 Bridger Drive Trunk Sewer Main Project. MEETING DATE: October 3, 2016 AGENDA ITEM TYPE: Consent RECOMMENDATION: Approve Resolution 4733 authorizing Change Order No. 1 to the 2016 Bridger Drive Trunk Sewer Main Project. BACKGROUND: Attached is a copy of resolution 4733 and change order number 1 for the above referenced project. During the bidding phase of the project, concerns were raised about the condition of the bridge across Bozeman Creek on Griffin Drive. This was to be the primary detour route for the project. Information on the condition of the bridge was requested from the County Road and Bridge Department who is responsible for all bridges in the county. They did not have an assessment at the time so had their consultant complete one. We did not receive the results until after the award of the project. The assessment resulted in the bridge being posted with a 3 ton weight limit which is not sufficient for large truck traffic. At that point, we were going to add the additional traffic control necessary to detour the truck traffic to the Wallace/Tamarack intersection to get in and out of the area, but the Wallace reconstruction project closed that intersection the week prior to the sewer project beginning. In order to route the truck traffic on Story Mill Drive through the sewer project, the contractor will need to widen the existing shoulder of the road, handle the excavated material in a different manner than planned, stop work as needed to allow trucks through, and construct a crossover in the area south of Hillside Drive where the sewer main crosses from the east side of Story Mill to the west side. All of this will add an additional two days to the installation of the sewer main plus one day for two people and a piece of equipment for cleanup and restoration. A detailed breakdown of the time and costs is attached. There is no additional contract time being requested with this change. The final recommended change in cost and time for these items is reasonable and commensurate with the work involved. UNRESOLVED ISSUES: None ALTERNATIVES: As suggested by the City Commission. 113 FISCAL EFFECTS: Overall this change order increases the contract amount by $24,570.14 from $420,912.00 to $445,482.14.
