BACKGROUND: Douglas-Kerr Underground, LLC was awarded a construction contract to complete the Old Village Phase 3 Street, Drainage, and Utility Improvements on May 16, 2017. The project is in construction with an anticipated substantial completion date of October 27, 2017. PROPOSAL DETAILS/ANALYSIS: Douglas-Kerr Underground, LLC has submitted a change order to address two design changes requested by the City as follows: 1. Remove the storm sewer piping and a stormwater treatment basin from the City Hall property. The stormwater treatment basin is no longer required after the City obtained a variance to the Valley Branch Watershed District rules. The variance was obtained after bids for the project were received. 2. The sanitary sewer main and service pipe was redesigned for the properties located at 11200 and 11240 Stillwater Boulevard to accommodate easement constraints and address separation requirements from existing water service lines. An 8-inch sewer main (in lieu 3 6-inch sewer services) was extended across the property of 11200 Stillwater Blvd using watermain pressure grade pipe. Separation from drinking water facilities caused a watermain grade pipe material to be necessary which was not included in the original bid. FISCAL IMPACT: This change order will decrease the contract in the amount of $16,586.70 bringing the revised construction contract to $1,559,452.45. With this change order the project remains within the authorized project budget and contingencies. RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent Agenda, Change Order No. 1 for the Old Village Phase 3 Street, Drainage, and Utility Improvements. If removed from the consent agenda, the recommended motion for the action is as follows: “Move to approve Change Order No. 1 for the Old Village Phase 3 Street, Drainage, and Utility Improvements, thereby decreasing the contract amount by $16,586.70”.
