BACKGROUND The Florida Department of Transportation (DOT) is encasing a drainage canal located on 16"' Street, between 3rd Court and 6`h Avenue (see attached location map). There are three.(3) existing 6" diameter water main canal crossings that are in conflict with the proposed drainage pipe. In addition, there are possibly up to fourteen (14) locations where drainage lateral pipes may be in conflict with existing 2 ;1", 3" and 6" diameter water and force mains. The DOT's design consultant, Dames & Moore has requested the Utilities Department to coordinate relocating the conflicts with their drainage contractor, once construction begins around the first part of July (see attached letter to Mr. James Davis, dated November 13, 1997). On September 21, 1993, the Board of County Commissioners approved the award of the Labor Contract (Bid No. 4007) to Driveways, Inc. (See attached meeting minutes for contract renewal). The Department of Utility Services requests that the Board of County Commissioners approve the attached contract with Driveways, Inc. to relocate the conflicting facilities away from the proposed drainage facilities. ANALYSIS Two of the three 6" water main crossings in conflict with the proposed drainage pipe will be replaced with one 10" DIP section constructed around the proposed drainage pipe. The other 6" water main crossing will be replaced with a 6" DIP section constructed around the proposed drainage pipe. Each of the fourteen (14) forcemain crossings will be rerouted around the drainage laterals as conflicts are identified by the drainage contractor. Driveways, Inc. has estimated that the labor portion of relocating the various water and force mains will be as high as $48,040.54 (assuming all 14 force main crossings have to be rerouted). The estimated total cost to relocate the facilities is $78,430.58. This includes $17,623.62 for material, a 10% contingency of $6,566.42 and $6,200.00 for engineering, inspects -ns and administrative cost (see attached cost estimates). The labor portion of this project has been estimated relatively high due to hardship conditions associated with cap rock known to be in the area. All engineering and admininstrative services will be done in-house. Funding for the project will be obtained from Fund No. 471. RECOMMENDATION The staff of the Department of Utility Services recommends that the Board of County Commissioners authorize the purchase of material from U.S. Filter/Davis Meter, approve the contract with Driveways, Inc. in the amount of $48,040.54, and authorize the Chairman to execute same, as presented.
