FROM: Bob Giberson, Public Works Director BY: Ryan Larson, Senior Program Manager CC: Mayor Ekberg DATE: September 9, 2016 SUBJECT: Crystal Springs Emergency Surface Water Repair Project No. 91641206 BID AWARD ISSUE Award contract for the construction of the Crystal Springs Emergency Surface Water Repair. BACKGROUND Maintenance staff was notified of pavement settlement within Crystal Springs Park and 51s' Ave S during the week of July 18, 2016. Using video inspection, it was determined that the surface water pipe was filled with a large quantity of material that indicated a possible failure of the pipe. Crews attempted to remove the blockage, but the removal of the material lead to additional failure of the pavement and a sinkhole. Other utilities are located within the settlement area. The Mayor declared an emergency on July 21, 2016 and Council approved Resolution 1887. Frank Coluccio Construction stabilized the emergency repair by filling the sinkhole, securing the utilities, and installing a bypass pipe. KPG was hired to design the permanent repairs for construction in 2016. DISCUSSION The Crystal Springs Emergency Surface Water Repair project was advertised for bids on August 30 and September 6, 2016. Bids are to be opened on September 13, 2016. Bid results are not currently available for the publication of the Utilities Committee Agenda, but due to the nature of this repair and the need to construct the permanent repair as soon as possible, staff will bring the bid results to the Utilities meeting for discussion and possible action. A bid tab and award recommendation, if applicable, will also be brought to the meeting. The engineer's estimate is $251,065.00.
