Mr. Vincent Burke, P.E July 27, 2020 Page 6 • It is assumed that all concrete and other solid waste, if encountered, will be taken to the IRC Landfill for disposal, and all Solid Waste Disposal District as a pass through to IRCDUS. • It is assumed that all tanks are empty. If product is present in the tanks, additional charges for the vacuum truck and liquid disposal may apply. • It is assumed that the liquid disposal will be completed as diesel or similar material. It is assumed that the results of the Waste oil and Spray Oil characterization will not require additional effort beyond what would be expected for disposal of diesel. • Based on the results of the Phase II ESA at the site, no herbicides or organophosphorus pesticides were detected. It is assumed that waste characterization for the spray oil tank will not identify these compounds. • It is assumed that the dived containment area is constructed as shown in Appendix H of the Phase I ESA. • The cost proposal does not include any remediation or investigation activities that are not specifically described herein. Additional assessment and remediation may be required. • A Sunshine State One -Call request for subsurface utility location will be completed. This proposal assumes there are no private utilities in the vicinity of the USTs, and no utilities that ae not covered by the Sunshine One Call. Any utilities in this area must be identified by IRCDUS. Tetra Tech is not responsible for the damage to subsurface infrastructure that is not identified by IRCDUS prior to Tetra Tech initiating AST Closure or Site Assessment activities. • "Face-to-face" meetings with regulators are not proposed as part of this work. • It is assumed that additional restrictions or limitations as a result of COVID-19, weather, or other unforeseen circumstances will not inhibit Tetra Techs level of effort or schedule. • Tetra Tech assumes that Draft reports will have only minor edits by IRCDUS. • Tetra Tech assumes IRCDUS will provide ready access to the Site as needed. PROJECT COST The estimated costs are based on our current understanding of the project requirements and best estimates of level of effort required to perform the basic services and may be subject to change upon agreement between Indian River County and Tetra Tech. The estimated project costs are shown in the attached Table 1. This project would be provided as a fixed fee for Tasks 1 through 5 $59,913.12, and additional time and materials for Tasks 6 and 7 not to exceed $19,719.94, for a total of $79,633.06. Indian River County will be invoiced each month for services rendered during the previous calendar month based on percent complete. Tetra Tech shall be paid for all invoices within 30 days of an approved submittal. TETRA TECH
