BOX 147 • CHANHASSEN, MINNESOTA 55317 ' \ (612) 937-1900 • FAX (612) 937-5739 MEMORANDUM TO: Don Ashworth, City Manager FROM: Gary Warren, City Engineer ; DATE: February 7 , 1990 SUBJ: Award of Bids for Test Well and Optional Observation Well for Well No. 5 , South Lotus Lake Area Improvement Project No. 89-4A As directed by the City Council, bids were solicited for the ' construction of a test well and optional observation well for Well No. 5 near South Lotus Lake Wellhouse No. 2. This is the first step in constructing the glacial drift well which we plan to develop at this same location. Attached is the bid tabulation for this project. The engineer 's estimate was $20 , 000 for this project. The bids ranged from ' $16, 368 to a low of $7 , 595 . The low bidder was Ben Ervin Well Company of Olivia, Minnesota. Our consultant, B. A. Liesch & Associates, has had experiences with Mr. Ervin and is very satisfied that they will do an excellent job. The bidders were also requested to provide an alternate bid for ' construction of an optional observation well on the site. Mr. Ervin 's bid for this effort is $2, 689. Depending on the results of the test well, it will be decided whether the observation well construction will be necessary or not. It is therefore recommended that the firm of Ben Ervin Well Company of Oliva, Minnesota be awarded the contract for test well construction for Well No. 5 in the amount of $7 ,595.00 . ktm Attachment: Bid tabulation . c: Jim Bullert, B. A. Liesch Jerry Boucher , Utility Superintendent I /I Manager' s Comments : It should be noted that funding for the eventual well was from the 1989 bonding program. Mr. MacGillivray, in our worksession, stated his belief that the water availability fund could pay future principal and interest ' payments , but that analyzing such should more appropriately occur in 1990. This decision recognized that the alternatives/ potential cost differentials were not known. As preliminary engineering costs of a construction project are coded against that project, staff will similarly establish a construction account for the new well. This point is being raised as, if the well is not found to be feasible, these costs will have to be ' recoded (rebudgeted) through an operating budget, i .e. water availability fund and pre-alerts are better than surprises.
