El REQUEST FOR ACTION River To Item Number Ci Council 6.1. Agenda Section Meeting Date Prepared by Public Works November 17, 2008 Te Maurer, Public Works Director Item Description Reviewed by Consideration of the Construction Bids fox 193rd Avenue Street Lori ohnson, Ci Administrator Improvement Project Reviewed by Tim Simon, Finance Director Action Requested There are three actions requested of the City Council regarding the 193' Avenue project. They are as follows: 1. Consider adoption of Resolution Accepting Bid and Authorizing Execution of Contract 2. Approve Supplemental Agreement, reducing the construction cost for the project 3. Authorizing the expenditure of $7,500 to purchase temporary easement on the Howse property Background/Discussion Competitive bids were opened for the construction of the 193`d Avenue Improvement project on Monday, October 13, 2008. There were a total of 16 bids received. The total bids ranged from $3,895,777.01 up to $5,018,730.65 (a copy of the full bid tabulation is attached). The low bid was received from R.L. Larson Excavating. R.L. Larson Excavating has successfully completed similar projects within the City of Elk River and we are prepared to recommend award to them as the lowest responsible bidder. We have received all of the approvals necessary from MnDOT to proceed with the award. In analyzing the total bid, the prices are in line with what was anticipated with the exception of an area of approximately 500 feet long near the intersection with CSAH 13 at the eastern end of the project. This is an area where soil borings taken after we received court-ordered access to the property indicated a pocket of unsuitable soils that extended at one point to a depth of approximately 20 feet. The area is in an existing wetland. In order to remove the unsuitable soils, protect the wetland, and stay within the right-of--way acquired by the city, contractors were asked to use innovative approaches, including sheet piling if necessary, for the construction of this portion of roadway. Once the total cost of this construction was realized, we immediately began discussing other options with our geotechnical consultant and began meetings with the apparent low bidder, R.L. Larson Excavating. Through these discussions, we have gone back to the Wetland Technical Evaluation Panel and asked for a modification, allowing us to disturb more wetland as long as it is restored after construction. We have received an amendment to our approved plan for this change. We have also worked with our eminent domain attorney, Howard Roston, who has been in contact with the attorney for the Howse property. They have indicated a willingness to provide the necessary temporary easement in exchange for $7,500 to construct the roadway without any innovative techniques. Through these efforts we have been able to negotiate a substantial contract price reduction included in Supplemental Agreement No. 1.
