The low quote of$14,846 was submitted by Penn Contracting. <br /> Staff has reviewed the quotes received and recommends approval. <br /> Penn Contracting Inc Dave Perkins Contracting C.W.Houle Inc. Hydrocon Inc. <br /> Construction: $12,606 $14,600 $15,999 $16,750 <br /> Alternate Cost: $2,240 $5,350 $7,785 $3,250 <br /> Total Cost: $14,846 $19,950 $23,784 $20,000 <br /> Explanation: When notified by a resident of a potential storm sewer issue between 2678 / 2712 Rice Creek <br /> Terrace, staff recently identified a downed tree; a corrugated metal pipe (CMP) section that separated from the <br /> main and landed in Rice Creek; and a subsequent washout of the embankment. Staff has made contact with <br /> Rice Creek Watershed District (RCWD) and they have since removed the downed tree from the channel. <br /> Additionally,RCWD staff indicated that an emergency repair in this location would not require a permit. <br /> Most of the existing pipe from Rice Creek Terrace to the outfall is concrete; however,the last few sections were <br /> constructed with CMP. Access from Rice Creek Terrace to this location with equipment is nearly impossible, <br /> and the embankment is essentially vertical (1:1). The repair plan will include extending the pipe to the base of <br /> the slope by adding bends/supports to the flow line of Rice Creek. The existing riprap along Rice Creek will be <br /> utilized to dissipate the stormwater energy from the pipe. Plans include soil anchors and coupling bands to <br /> prevent pipe separation. If the existing vegetation/trees are disturbed alternate landscape improvements will <br /> include new trees and native plantings (sandbar willows) to aid in slope stabilization. The proposed project <br /> schedule is as follows: <br /> o City Council Awards Project to Low Bidder February 12,2013 <br /> o Anticipated Start Date February 25,2013 <br /> o Project Completion Date March 29,2013 <br /> o Landscaping to take place as weather permits in spring <br /> Costs and Funding: The total cost of this project will paid for from the storm water enterprise account—Fund <br /> 703-4 500-351 <br /> Grant M.
