Item 4BCITY OF SOUTHLAKE MEMORANDUM (September 15, 2009) To: Shana Yelverton, City Manager From: Robert H. Price, P.E., Director of Public Works Subject: Award construction contract for the Quail Creek Neighborhood Sewer to Quality Excavation, Ltd. in the amount of $630,891.15 and authorize construction phase contingencies Action Requested: Award construction contract for the Quail Creek Neighborhood Sewer to Quality Excavation, Ltd. in the amount of $630,891.15 and authorize construction phase contingencies. Background Information: The Capital Improvements Program (CIP) includes funds for the construction of sanitary sewer improvements for Quail Creek Estates. Cheatham and Associates has designed and prepared construction plans for the project. Quail Creek Estates was previously included in a construction contract with Hall Albert Construction, LP along with Woodland Heights sanitary sewer improvements and a 12" waterline on Continental Boulevard. Hall Albert and the City mutually agreed to delete the Quail Creek Estates sanitary sewer improvements from their contract. The project was rebid on May 19, 2009, but only two bids were received. The City staff did not feel this was a representative number of bidders for the project. Staff recommended and the City Council approved rejecting all bids. Staff was directed to evaluate the engineering design and the specified construction method to determine if the project would be more suitable using primarily an open cut method of construction rather than directional drilling The sanitary sewer will be located approximately 5 feet off the edge of pavement within the street right of way and will be in fairly open right of way where there are few trees along the alignment. This type of location is more suitable for open cut construction than if the line were planned to be in easements along rear lot lines or in heavily treed areas. There are several locations that will utilize directional drilling under selected locations including driveways constructed with exposed aggregate and under a culvert to avoid disturbing the flow line of the drainage way. Also selected for directional drilling is a location between two resident's properties in order to connect to an existing sanitary sewer line along their south property line. Five (5) bids were received on September 3, 2009. The bids have been reviewed by Cheatham and Associates and the City Staff and are tabulated as follows: BIDDER BID AMOUNT Quality Excavation, Ltd. $630,891.15 J.T. Dersner, Inc. $698,123.35 Municipal Utilities $704,169.70 Barson Utilities, Inc. $708,373.95 North Texas Contracting, Inc. $774,582.50 Cheatham and Associates recommends award of the contract to the low bidder, Quality Excavation, Ltd. The City Staff concurs in this recommendation. Financial Considerations: The recommended contract award amount is $630,891.15. Staff also recommends that the City Council approve an approximate 10% construction phase contingency of $64,108.85 for a total project budget of $695,000.00. Staff recommends funding the project from the following existing CIP accounts: 502699-598804-00028 $ 695,000.00 Strategic Link: The construction of the sanitary sewer improvements within the Quail Creek Estates 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 sanitary sewer infrastructure include: Providing High Quality Customer Service and Investing to provide and maintain high quality public assets. Citizen Input/ Board Review: N/A 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 Quality Excavation, Ltd. or reject all bids.
