Home My WebLink AboutItem 06.gDate: 27 September 2013 Lakeville APPROVAL OF THE 168TH STREET BRIDGE REPLACEMENT PROJECT CHANGE ORDER NO.1 Proposed Action Staff recommends adoption of the following motion: Move to approve the 168' Street Bridge Replacement Project Change Order No. l increasing the contract sum in the amount of $ 7,364.60. Passage of this motion will result in the installation of two water main gate valves on the existing water main that runs beneath the North Creek drainage channel. Overview This change order adds the installation of two water main gate valves to the existing 6 -inch water main that runs beneath the North Creek drainage channel at the intersection of 168th Street and Gannon Avenue. The water main currently has valves at 168t Street and Gerdine Path and at Gannon Avenue and Garland Way. Should the water main fail at any point between those valves, it would mean shutting off water service for approximately 24 properties. The gate valves will be installed on either side of the new bridge to reduce the impact of a water shutoff to property owners. It also divides this long segment of water main into three distinct parts which will allow the isolation of the segment under the bridge, should it fail, without affecting water service to any property. Cost of the gate valve installation is $7,364.60. Staff has reviewed the change order and recommends approval. Primary Issues to Consider • What is the impact to the contract? This change order increases the contract by $7,364.60 to a total of $315,950.60. • How important is this change to the project? It is important in minimizing the impact of a water shutoff to properties along this segment of water main.

An existing 6 -inch water main exists beneath the North Creek Drainage Channel crossing at the intersection of 168 Street and Gannon Avenue, over which the 168 Street Bridge is currently being replaced. As very few water main valves exist in the area, City Staff desires to install two (2) new 6 -inch water main gate valves on either side of the new bridge, so that service areas within the City's water distribution system can be better isolated in the event there is a water main failure under the bridge. The increase to the contract amount is $7,364.60, resulting in a new contract total of $315,950.60. This change order amount will be shown on the next construction pay voucher processed. We hereby recommend that the City of Lakeville approve Change Order No. 1 for Redstone Construction.
