~L~RIN~ ~ ~ASSO(I~AT~S TpUd NUBTA February 11, 2009 File No. 120106E-0060 Honorable Mayor and City Council City of Little Canada 515 Little Canada Road East Little Canada, MN 55117-1633 SUBJECT: Cobblestone Storm Repair Project Recommendation of Award Dear Mayor and Council Members: Bids were opened for the above referenced project at 10:00 a.m. on Wednesday February 11, 2009 in accordance with the Advertisement for Bids. The project includes the installation of storm sewer by directional bore located off of Stephani Circle to replace an existing storm pipe that has deteriorated and is resulting in significant erosion. Five (5) bids were received from the following companies in order from low to high: Corporation Frattalone Companies, Inc S-K Contracting, Inc. Peterson Companies, Inc. Penn Contracting, Inc. Ellingson Drainage, Inc. Base Bid $ 82,734.50 $120,250.00 $120,767.05 $138,781.00 $146,614.59 Based on the bids received, Frattalone Companies is the low bidder. The low bid received appears to be highly competitive and the bids have been reviewed for errors and/or omissions. The differentiating item between the low bid and the second bid was the significantly lower unit price for the directionally drilling. The exiting hole for the directional drill is next to a wetland and approximately 50 feet below the townhomes making access with large equipment very difficult. During the drilling process a hole is drilled through the soil and this material is carried out of the hole with the drilling fluid. This mixture of water, bentonite, and soil is commonly referred to as slurry. While the slurry is non-toxic it cannot be allowed to enter the wetland and therefore must be collected and taken off-site. It is estimated that approximately 24 gallons of slurry would be produced per foot of pipe drilling. Based on the discussions at the pre-bid meeting the Contractors indicated that the disposal of the slurry would drive the cost of the directional drilling significantly higher than if the exiting hole was more accessible with a standard vacuum system. Due to the large discrepancy between the low and second bid amounts, Frattalone Companies was contacted to determine if they would honor their bid. They indicated that their directional drilling subcontractor had stated that they could vacuum the slurry up the steep grade for disposal. Frattalone Companies has previously completed work within the City and we would consider them to be a responsible, responsive bidder. itr-0211098• CC (Project Award) 2 10062 Flanders Court NE, Blaine, MN 55449 - Ph: (763) 780-0450 -Fax: (763) 780-0452
