JANONIS FROM: WATER/SEWER SUPERINTENDENT DATE: MAY 7, 2012 SUBJ: BID RESULTS FOR SEWER REPAIRS USING CURED -IN- PLACE -PIPE (CIPP) PROCESS ($661,431) Background In the current budget, staff requested funds to continue the combined sewer system repairs. These repairs were identified during the Combined Sewer System Evaluation Study ( CSSES) completed in 2004. In total, almost $15 million worth of sanitary sewer repair work has been slated. This work primarily consists of rehabilitating existing sewer main pipes using a no -dig, cured -in- place -pipe (CIPP) process. To facilitate this work, staff prepared two (2) separate bid packages. One package was designed to solicit contractors for rehabilitating sewer mains using the CIPP process. The other bid package was drafted to procure the services of a sewer excavation contractor capable of replacing structurally failed pipe. The CSSES ranked defects in a range of categories with Category 5 being pipes in the worst condition and Category 1 pipes requiring little or no rehabilitation. The rehabilitation work performed since 2005 resulted in the elimination of the worst defects (100% of Category 5). Approximately 95% of the Category 4, 17% of the Category 3 and 5% of Category 2 defects in our combined sewer system have been lined to date. A total of 67,028 lineal feet (over 12 miles) of sewer has been lined under this project In addition, each year the Village also repairs a portion of the separate sanitary sewer system. This work in the separate sewer system also utilizes the CIPP process. This separate sanitary sewer work has also been included in these bid packages. Distinct funds were appropriated in the current budget for these improvements. This memorandum presents the results of the bids for the CIPP work. Bid results for spot relays will be presented in a separate document. The locations of the work planned for the proposed CIPP award is outlined in Attachment A. This year's proposed project features 16,690 lineal feet of lining work in pipes ranging from 8" to 36" in diameter along with the televising and cleaning of approximately 50,000 lineal feet of sewers Page 2 of 3 BID RESULTS FOR SEWER REPAIRS USING CURED -IN- PLACE -PIPE (CIPP) PROCESS ($661,431) MAY 7, 2012 Bid Results Prior to letting, six (6) invitational bids were distributed to contractors experienced in the CIPP process. Public notice was posted in a local newspaper as required. An additional two (2) bid sets were released to other contractors. Sealed bids were received until 1:00 P.M. on Monday, May 14, 2012 at which time they were opened and read aloud. Four (4) bids were received. The bid results are as follows: Bidder Bid Visu -Sewer of Illinois, LLC of Bridgeview, IL $ 601,301.00 Insituform Technologies of Chesterfield, MO $ 608,831.00 Hoerr Construction, Peoria, IL $ 763,293.70 Kenny Construction, Northbrook, IL $ 891,774.10 Discussion Staff has evaluated all bids. All bidders submitted the required bid securities. Hoerr Construction of Peoria, IL did not submit references or confirmation that they meet the bid requirements for lineal footage installed for the lining system, lineal footage installed for the contractor, or whether Hoerr Construction is an authorized licensee of an acceptable CIPP system. Consequently, the bid submitted by Hoerr Construction is considered non - responsive. All other bidders satisfied the bid qualifications and submitted responsive bids Visu -Sewer of Illinois, LLC of, Bridgeview, IL is the apparent low bidder and provided all the necessary material and references as outlined in the bid specification. Visu -Sewer has done work for the Village in the past and their work has been satisfactory. Staff is recommending that a 10% contingency ($60,130.00) be added to the contract to cover any unforeseen expenses. A contingency would cover the difference between actual lineal footages and the estimates used to prepare the bid specifications, address unforeseen sewer services that would need to be reinstated and make any other small repairs needed to be performed prior to the lining of the sewer. The contingency would raise the total project cost to $661,431.00 ($601,301.00 base bid plus the contingency of $60,130.00). Page 3 of 3 BID RESULTS FOR SEWER REPAIRS USING CURED -IN- PLACE -PIPE (CIPP) PROCESS ($661,431) MAY 7, 2012 Recommendation I recommend that the Village Board award the 2012 combined and sanitary sewer repairs using the CIPP process project to Visu -Sewer of Illinois, LLC of Bridgeview, Illinois in the amount of $661,431.00. Sufficient funds for this proposed contract exist in the current budget. Superintendent of Water & Sewer Director of Public Works H: \Water \CIPP\2012 CIPP \CIPP board report 2012.doc
