INDIAN RIVER COUNTY, FLORIDA <br />BOARD MEMORANDUM <br />TO: Joseph A. Baird, <br />County Administrator <br />THROUGH: Christopher R. Mora, P.E. <br />Public Works Director <br />FROM: James D. Gray, Jr. <br />Coastal Engineer �Vl� <br />CONSEN <br />SUBJECT: Sector 3 Dune Repair Project, Change Order No. 2 <br />Contract Increase - Additional Sand Fill <br />Guettler Brothers Construction, LLC <br />DATE: March 17, 2015 <br />DESCRIPTION AND CONDITIONS <br />On July 8, 2014, the Board of County Commissioners awarded a contract to Guettler <br />Brothers Construction, LLC. (Guettler) to repair the dunes damaged by Hurricane Sandy <br />(October, 2012) within the Sector 3 Beach and Dune Restoration Project area. The project <br />utilizes sand from mined upland sand sources transported to the beach in trucks. The <br />project will repair approximately 31,000 feet (5.9 miles) of storm damaged dunes by <br />placing approximately 154,700 cubic yards of beach compatible sand landward of the <br />mean high water line (MHWL). As required by permit all sand placement must occur prior <br />to April 30, 2015. The total awarded contract amount was $3,076,920. <br />On November 4, 2014, the Board approved Change Order No. 1 which eliminated the 75% <br />Sand Stockpile Provision of the contract, but did not modify the contract amount which <br />remained at $3,076,920. <br />As of March 16, 2015, Guettler has constructed approximately 90% of the project area <br />however has reached nearly 100% of the contact quantity of 154,700 cubic yards for sand <br />fill. Staff determined that additional sand was needed to fully construct the project <br />following recent erosion resulting from the December 2014 and January 2015 Nor'easters. <br />Based on survey data provided by Guettler, our engineer has forecasted a new total <br />volume to fully complete the project as designed to be approximately 175,000 cubic yards, <br />which represents a 20,300 cubic yards/13.1% increase in the contract quantity for sand fill. <br />M:\Coastal Docs\Final Change Order No 2 - Sector 3 Dune Repair Project -- 3-24-15.docx <br />25 <br />
