NOV 231993 BOOK 91 FACE Commissioner Macht asked Director Price to organize the information in a presentable form to be carried to Tallahassee for the meeting of the Florida Association. of Counties. The Board members concurred in that request. PARTIAL PAYMENT TO AMERICAN COASTAL ENGINEERING INC. a FOR THE 1.500 FEET OF ADDITIONAL JET PROBE AND SEDIMENT SAMPLING FOR THE PREFABRICATED EROSION PREVENTION (PEP) REEF PROJECT The Board reviewed memo from Coastal Engineer Don Donaldson dated November 16, 1993: TO: James E. Chandler, County Administrator THROUGH: James W. Davis, P.E., Public Works Director FROM: Don G. Donaldson, P.E. Coastal Engineer SUBJECT: Partial Payment to American Coastal Engineering, Inc. for the 1,500 Feet of Additional Jet Probe and Sediment Sampling for the PEP Reef Project DATE: November 16, 1993 DESCRIPTION AND CONDITIONS MME -2 ANHRC=.a= The Beach and Shore Preservation Advisory.Committee voted on Oct. 13, 1993 to instruct American Coastal Engineering, Inc. to jet probe 6,000 feet, permit 4,000 feet and build a 3,000 feet reef. The County's Contract with American Coastal Engineering dated Sept. 28, 1993 authorized American Coastal Engineering to design and permit a 3,000 feet reef. The Beach and Shore Preservation Advisory Committee authorized expanding the survey to 6,000 feet so that we would have the necessary information to expand the project if additional funding is available. After reviewing proposed cost estimates for the additional 3,000 feet of survey, staff authorized American Coastal Engineering investigate only additional 1,000 feet. However, due to the uncertainty of the exact placement of the proposed PEP Reef American Coastal Engineers jet probed a total of 4,500 feet which is 1,500 feet greater than our original contract and is 500 feet greater than what was authorized by staff. After reviewing the data, staff concurs with American Coastal Engineering that the additional 500 feet was necessary to ensure proper coverage for the proposed 4,000 feet of PEP Reef. The county's contract with American Coastal Engineering provided that 50% of Task I would be paid at the signing of the contract. The remainder of Task I would be paid upon completion of Task I. The jet probes and sediment analysis are included in Task I. RECOMMENDATIONS AND FUNDING Staff recommends that the Board authorize a 50% payment to American Coastal Engineering in the amount of $2,870 for the additional services they have provided. The remaining $2,870 will be included in the final payment for Task I when it is complete. 48 77 M
