DEPARTMENTAL INDIAN RIVER COUNTY, FLORIDA MEMORANDUM TO: Jason E. Brown, County Administrator THROUGH: Richard B. Szpyrka, P.E., Public Works Director FROM: James W. Ennis, P.E., PMP, Asst. Public Works Director SUBJECT: Sector 5 Beach & Dune Restoration Project- Hurricane Dorian Repairs Change Order No. 1 (IRC -1923) DATE: November 27, 2019 DESCRIPTION AND CONDITIONS On September 17, 2019 the Board of County Commissioners awarded Bid No. 2019066 to Rio -Bak Corporation (Contractor) for the Sector 5 Beach and Dune Restoration Project in the amount of $4,511,712.00. A notice to proceed was issued on October 27, 2019 with a contract time of 210 days to final completion. During the time when the project was being advertised and award ofthe project was being prepared bystaff for action by the Board, Indian River County was impacted by Hurricane Dorian. The eye of Hurricane Dorian passed approximately 105 miles offshore of Vero Beach on September 3, 2019. At the time of the September 17, 2019 Board meeting, it was estimated that 50,000 cubic yards of sand was eroded from the Sector 5 project area due to storm activity and Public Works Staff estimated the cost to replace sand lost from Hurricane Dorian at approximately $1,250,000.00. This was noted in the Public Works Department's recommendation of award to IRC Board of County Commissioners. Public Works staff in concert with our Design Consultant, APTIM, has determined that due to Hurricane Dorian an additional 61,555 cubic yards (83,100 tons) of sand is required to restore the permitted beach profile of Sector 5 to the intended design conditions set forth in the originally advertised construction bid plans. Based upon this quantity, a cost proposal was requested from the Contractor for the placement of additional sand with the stipulation that all sand placement had to occur within the current allotted project time. The Contractor provided a cost proposal to accomplish the additional work as detailed in proposed Change Order #1 (see attached). The cost for supply/deliver/placement of sand by the ton increased by $0.58 from $21.60 per ton to $22.18 per ton. This is a reasonable increase due to the fact that the additional sand will need to be added without an extension of the contract time. Additional costs for Mobilization/Demobilization ($27,772.02) and Environmental Compliance ($8,310) for the Post -Dorian placement of sand were also included in Change Order #1. County staff has reviewed the proposed change order for $1,879,240.02 and found the cost to be in line with similar work and consistent with additional materials, labor, equipment, bonding, and compliance efforts required for the Contractor to successfully construct the project within the original allotted timeframe. FUNDING: Local Funding for beach restoration is provided by a portion of Local Option Tourist Tax. Funding for construction of the Sector 5 Beach and Dune Restoration Project in the amount of $4,511,712.00 was 76 C:\Users\legistar\AppData\Local\Temp\BCL Technologies\easyPDF 8\@BCL@ACOE2B93\@BCL@ACOE2B93.doc
