About this file

This document is a Task Assignment Change Order (TACO) executed between the State of Florida Department of Environmental Protection (Department) and GHD Services Inc. (Contractor) for site inspection activities at Applied Electronic Technology (ERIC_9110) located at 257 S Lake Destiny Drive, Orlando, Florida. The change order, effective November 18, 2025, amends the original Task Assignment CSS03B and incorporates modifications to project scope and associated costs. The Department's Project Manager is Claire Field, and the Contractor's Project Manager is Brian Moore, a Principal Engineer/Scientist.

The TACO authorizes a reduction in overall task assignment cost from $50,657.41 to $44,796.41, representing a net decrease of $5,861.00. This change results from a reduction in laboratory testing requirements in Subtask 2 (Site Investigation Activities), which decreased costs by $6,323.00, offset partially by the addition of Subtask 4 (IDW Management) for PFAS and PFOS contamination management, which increased costs by $462.00. The task includes four subtasks: Project Management (Subtask 1, $1,522.49), Field Sampling (Subtask 2, $37,102.58), Site Inspection Report (Subtask 3, $5,709.34), and IDW Management (Subtask 4, $462.00). Deliverables are due by September 18, 2025, with invoicing structured in three phases based on departmental approval of specific work products. No changes were made to the task completion date or attachments.

Hey Brian, I just looked over the labs and there are detections for PFAS. We have separate rates for PFAS contaminated media. There is a $350.00 one time profiling fee and the drums are $195.00 per drum. For this one, it will be $545.00 total. Are you ok with this?
