Title
FDOT SR 26A Roadway Reconstruction Project - Water Main and Force Main Crossings by Horizontal Directional Drilling (B)
Explanation
An existing 12-inch iron pipe water main and 10-inch iron pipe force main cross under Hogtown Creek adjacent to the SW 2nd Avenue roadway bridge that crosses the creek. The FDOT SR 26A roadway reconstruction project includes widening of the existing bridge. The additional bridge width and associated new pilings will result in the existing 12-inch and 10-inch pipelines being located underneath the expanded bridge cross-section. The FDOT is requiring GRU to relocate the two existing pipelines as part of the approved FDOT Utility Work Schedule. To provide for possible future growth, GRU has determined that approximately 450 feet of 16-inch water main and 450 feet of 12-inch force main will be installed using high density polyethylene (HDPE) pipe. The new pipeline crossings will be constructed under Hogtown Creek using the horizontal directional drilling method which has been approved by the St. Johns River Water Management District. GRU has applied for the required Florida Department of Transportation and Florida Department of Environmental Protection construction permits.
Written price quotations were obtained from the two known horizontal directional bore contractors that have successfully performed work for GRU. The lowest quotation was submitted by Peters Utilities, LLC. The recommended approval amount includes contingency funds in the amount of $19,000 for the possibility of unknown underground conditions that may adversely impact construction progress and impact other aspects of the project cost. A tabulation of the quotations is attached for your reference.
Recommendations
The City Commission approve the issuance of a purchase order to Peters Utilities, LLC. for construction of a 16-inch water main and a 12-inch force main crossing under along SR 26A (SW 2nd Avenue) in an amount not to exceed $70,000.
Fiscal Note
Funding for this work is in the FY 2004 - 2005 Water/Wastewater Systems budget.
