CASE BY AUTHORIZE CONSTRUCTION OF IMPROVEMENT PROJECT g92-19 AND #92-12 CHANGE ORDER TO BONINE EXCAVATING, INC. (SEWER AND WATER EXTENSION TO 149TH AVENUE N.W. AND COUNTY ROAD #5) By: Steve Jankowski, City Engineer Background: Last fall, the City awarded a $417,296 contract to Bonine Excavating, Inc. of Elk River for the construction of the sanitary sewer, watermain, storm sewer, and street improvements in the Sunny Ponds subdivision. The project was competitively bid by nine area contractors and was awarded to the low bidder, Bonine Excavating, Inc. of Elk River. After the award of the Sunny Ponds project, two petitions for similar improvement projects were received from residents of 149th Lane N.W. and a property owner on the west side of County Road #5. Project g92-19 and g02-12 were established in response to these petitions and have progressed to the point that plans for their construction are now complete. The contractor has not completed the work on the Sunny Ponds subdivision which was interrupted by the winter weather and has his equipment on site. State Statutes allows for increasing the scope of a project by up to 25% of the original contract at the same unit prices. The contractor is agreeable to performing the work for Project g02-19 and g02-12 at the same unit prices bid for the Sunny Ponds project. I am recommending that construction for Project g92-19 and g02-12 be authorized by a Change Order. The estimated costs, which are $60,998.45 and $7,166.20, respectively, request an approximate 16% increase in the scope of the project which is well within the allowable 25%. Awarding the work in this manner will also reduce the amount of construction operations in the area to a single contractor. In addition, I believe the unit prices established are am'active. They represent a competitively bid unit price for raw land construction. The cost for construction in developed constricted locations, which both these projects represent, could be expected to be bid at higher unit prices. The cost of each project is reasonably close or lower than the construction cost estimated in the respective feasibility studies. Project g'92-19, the 149th Lane N.W. extension, has a Change Order price of $60,998.45 which compares to $58,516 in the feasibility study. A portion of the increase is attributable to the addition of a 12" watermain where previously a six inch main had been anticipated. This change was caused by the lack of connection between 149th Lane N.W. and 150th Lane N.W. as previously anticipated. The City trunk fund is anticipated to contribute approximately $1,100 toward this increased cash. It is even possible that the scope of the storm sewer associated with this project may be reduced in conjunction with the potential development of the Ramsey Commons 2nd Addition subdivision. Project g92-12, the County Road #5 sewer extension, has a Change Order price of $7,166.20 compared to a feasibility estimate of $14,780. The City will provide traffic control directly for this project at an estimated cost of $4,625, as no comparable unit price bid was available in the existing project. With the addition on the traffic control, this project will be approximately $3,000 below the feasibilit3, study estimate. ?/
