Summary

This document is a Task Assignment Notification and Change Order #2 for Florida Department of Environmental Protection (FDEP) Contract No. HW553. The contract is between FDEP and Ecology and Environment, Inc. (E&E), with Perry Kelso serving as the contractor representative and Daisy Sim as the FDEP Contract Manager. The work is being performed at the Prestige Cleaners facility in Tallahassee, Leon County, Florida (Facility ID 379502252, ERIC 4873), where a Soil Vapor Extraction (SVE) system is being operated and maintained.

The change order reduces the total task cost from $31,570.29 to $28,450.59, representing a net decrease of $3,119.70. This cost reduction reflects the early termination of operations and maintenance (O&M) services by approximately one month, as documented in the Ecology & Environment June 18, 2018 level of effort and cost estimate. The payment of utilities under this task assignment is structured as Cost Plus Fixed Fee. Specific changes include: deletion of one field visit with sampling in Subtask 6 (reducing costs by $2,093.99); removal of one month of utility service charges and handling fees in Subtask 8 (reducing costs by $894.00); and adjustments to associated labor and other direct costs. The final deliverables include three monthly O&M checklists, annual sample data, and an Annual RASS Report with FDEP EDDs, with a final deliverable due date of July 9, 2018. The task completion date has been extended by 14 days from August 26, 2018 to September 9, 2018 as a result of this change order.
