INDIAN RIVER COUNTY <br />OFFICE OF MANAGEMENT AND BUDGET <br />PURCHASING DIVISION <br />DATE: February 9, 2021 <br />TO: BOARD OF COUNTY COMMISSIONERS <br />THROUGH: Jason E. Brown, County Administrator <br />Kristin Daniels, Director, Office of Management and Budget <br />FROM: Jennifer Hyde, Purchasing Manager <br />SUBJECT: Modification to Purchase of Enviro-Blocks from Inter -Block Retaining Systems, Inc. <br />BACKGROUND: <br />On June 9, 2020, the SWDD Board waived the requirement for bids for the purchase and installation of <br />Inter -Block Retaining Systems, Inc. (Inter -Block's) Enviro-Blocks to create storage bays for a new facility for <br />the transfer of corrugated cardboard. The total cost was $246,165. Site work in preparation for the <br />installation of the blocks is nearly complete. <br />ANALYSIS: <br />Since the Board's original approval, the price of steel angle iron used in the stabilization of the blocks as <br />they are installed has increased, and therefore the vendor has requested an increase of $6,840 (from $57 <br />per foot to $79.80 per foot). Because site work was not completed as quickly as anticipated, staff finds this <br />request justified. <br />Four additional 3 -cross beam blocks have been added to the project, at a total cost of $6,380, to provide <br />flexibility in installing additional perpendicular walls to segregate additional materials (i.e., tires, white <br />goods) in the future. <br />Finally, at staff's request, Inter -Block has agreed to provide the labor and equipment to construct a rock <br />and geogrid base ramp for access into the facility, utilizing materials already available on site. This work <br />adds $2,200 to the overall project. <br />SOURCE OF FUNDS: <br />Funding for the additional work in the amount of $15,420 is budgeted and available in the capital funds <br />allocated for Fiscal Year 20/21 in the SWDD/Other Improvements account, which is funded from SWDD <br />assessments and user fees. <br />Account Name <br />Account Number <br />Amount <br />SWDD/Other Improvements <br />411-164051 <br />$15,420 <br />RECOMMENDATION: <br />Staff recommends that its Board approve the additional work and the estimate from Inter -Block Retaining <br />Systems, and authorize the Purchasing Manager to encumber the additional $15,420 via purchase order. <br />Attachment: <br />Proposal from Inter -Block Retaining Systems, Inc. 22 <br />
