Item 4CCITY OF SOUTH LAKE MEMORANDUM (February 3, 2009) To: Shana Yelverton, City Manager From: Robert H. Price, P.E., Director of Public Works Subject: Award construction contract for Segments A and F of the T.W. King 30 inch water supply line to Circle C Construction, Ltd., in the amount of $2,635,235 and authorize construction phase contingencies. Action Requested: Award construction contract for Segments A and F of the T.W. King 30 inch water supply line to Circle C Construction, Ltd., in the amount of $2,635,235 and authorize construction phase contingencies. Background Information: The FY 2007 and FY 2008 Capital Improvements Program (CIP) budget included funds for the construction of segments A and F of the T.W. King 30 inch water supply line. Currently, the City of Southlake purchases water on a wholesale basis from the City of Fort Worth. The water is received and temporarily stored in two 5 MDG ground storage tanks located near the northeast corner of Pearson and Southlake Blvd (FM 1709). The water is pumped to the Miron elevated storage tank and ultimately to the Dove elevated storage tank on the north side of the city. The city's water master plan calls for a new transmission water line to be constructed that will supply water directly to the TW King pump station that feeds the north side of the city. On February 20, 2007, the City Council awarded a contract to Freese and Nichols to perform a Route Analysis Study to determine possible alignments for the new water supply pipeline to the T.W. King Pump Station located in the northern part of the city. The exact alignment of entire water line is yet to be determined; however, segments A and F are common to both alignments outlined in the route study and therefore construction of these segments can proceed without risk. Segment A will be constructed from the intersection of Pearson Lane and Florence Road at the end of the existing 42" water line and to the intersection of Randol Mill Road (FM 1938) and Florence Road. The second portion of this design project, Segment F, begins at the north side of SH 114 and T.W. King intersection and connects to the T.W. King Pump Station. The total scope of this portion of the project is the construction of approximately 7,500 If of 30" water transmission line. On December 18, 2007, the City Council approved a professional services agreement with Freese and Nichols, Inc. for the design and preparation of construction plans for these improvements. Six (6) bids were received on January 20, 2009. The bids have been reviewed by Freese and Nichols, Inc. and the City Staff and are tabulated as follows: BIDDER Circle C Construction Cash Construction Co., Inc. W.R. Hodgson Co., LP S.J. Louis Construction, Inc. Tri Dal Utilities, LTD North Texas Contracting, Inc BID AMOUNT $2,635,235.00 $3,293,580.00 $3,596,712.50 $3,531,514.00 $3,814,195.00 $4,076,040.00 Freese and Nichols, Inc. recommends award of the contract to the low bidder, Circle C Construction. The City Staff concurs in this recommendation. Financial Considerations: The recommended award amount is $2,635,235. Staff also recommends that the City Council approve approximately a 10% construction phase contingency of $263,565 in addition to the award of $2,635,235 for a total project budget of $2,898,800. The FY 2007 and FY 2008 Capital Improvements Program (CIP) included funds for the construction of the T.W. King 30 inch water supply line. The unencumbered funding available for Segments A and F is $4,254,230. The FY 2009 CIP included an additional $4,500,000 for construction of the T. W. King water line. This provides $8,754,230.00 in total unencumbered budgeted funding available for the entire length of the 30 inch water supply line. The most recent engineer's opinion of probable cost is $10,853,300 including engineering and right of way /easements. Additional funds will be requested in the upcoming FY 2010 CIP budget. Strategic Link: The construction of the new 30 inch water supply line links to the city's strategy map relative to the focus areas of Infrastructure and Performance Management and Service Delivery. The specific corporate objectives that are met by the construction of this new water transmission infrastructure include: Providing High Quality Customer Service and Investing to provide and maintain high quality public assets. Citizen Input/ Board Review: None Legal Review: This is the standard construction services contract that has been previously reviewed by the City Attorney. Alternatives: The Council may award the contract to Circle C Construction or reject all bids. Supporting Documents: Bid Tabulation, Recommendation Letter Location Map Project Schedule: 275 calendar days are allotted from the date of Notice to Proceed for this project. It is anticipated that construction of segments A and F will begin in March of 2009 and be completed in November of 2009. Staff Recommendation: Award construction contract for segments A and F of the T.W. King 30 inch water supply line to Circle C Construction, Ltd., in the amount of $2,635,235 and authorize construction phase contingencies. Staff Contact: Robert H.
