INDIAN RIVER COUNTY, FLORIDA MEMORANDUM TO: Joseph A. Baird, County Administrator THROUGH: Christopher R. Mora, P.E., Public Works Director FROM: Christopher J. Kafer, Jr., P.E., County Engine �y SUBJECT: Work Order No. 3 with Bridge Design Associates, Inc. 13th Street S.W. Bridge over the IRFWCD Sub -Lateral B-8 Canal (58th Avenue) IRC Project No. 0530 DATE: November 19, 2013 DESCRIPTION AND CONDITIONS On October 3, 2006, County Commissioners approved Work Order No.1 with Bridge Design Associates, Inc. for design of a three -lane bridge on 13th Street S.W. over the Sub -Lateral B-8 Canal (58th Avenue) in the amount of $32,050.00. In 2008, the Board of County Commissioners approved the Capital Improvement Element of the Comprehensive Plan, eliminating the funding for the construction of the 13th Street S.W. Bridge over the IRFWCD Sub -Lateral B-8 Canal (58th Avenue). On August 21, 2012, the Board of County Commissioners approved terminating the design project for the bridge and paid Bridge Design Associates, Inc. 50% of the contract amount. Recently, the Florida Department of Transportation (FDOT), through their Bridge Inspection Program, inspected the subject bridge and determined that substantial repair is required to insure safe travel across the bridge. Estimated cost to provide repairs to this bridge is $50,000.00. The existing bridge is a narrow 2 - lane bridge, built in 1962 and is classified by FDOT as "Functionally Obsolete." The repairs to the existing bridge would include removal of the entire bridge, replacement of all the wooden piles, construct pile caps, and re -installation of the deck units. When completed, the bridge would still be a narrow 2 -lane bridge, classified by FDOT as "Functionally Obsolete," and have a 52 year-old superstructure (deck surface). Therefore, to avoid putting money into an old bridge that may have an extended life expectancy of 5 to 10 years, staff considers designing and constructing a new 3 -lane bridge and installing asphalt millings on the unpaved portion of 58th Avenue from 13th Street S.W. to south of Oslo Road as a long term solution to improve the roadway network in this area. FUNDING Due to the fact that this project was previously eliminated, funds are not currently budgeted. However, funding is available for this project from Secondary Roads/13th Street, SW/43`d Avenue to 58th Avenue in the amount of $53,665.00.
