This document package represents a Task Assignment Notification Change Order for Contract HW551, managed by the Florida Department of Environmental Protection (FDEP) and executed by AECOM Technical Services, Inc. (AECOM) as the primary contractor. The contract involves soil and groundwater sampling work at the Aircraft Cleaners facility (ERIC_4413) located at 18405 NW 7th Avenue, Miami, Florida. Brandie Stringer serves as the FDEP Contract Manager, with Mark Rasberry representing AECOM. The deliverable package includes supporting documentation such as cost estimates, subcontractor bid summaries, GPRS utility location proposals, drilling quotes from Earth Tech Drilling and Groundwater Protection, and email correspondence detailing project scope modifications and vendor selections.

The task assignment involves Natural Attenuation Monitoring and Soil Sampling at the Aircraft Cleaners site, with the original task amount of $10,352.30 increased by $5,228.43 through Change Order #1, resulting in a total task amount of $15,580.73. The scope was expanded to address contractor refusal at the initial sampling depth, requiring additional mobilization costs to complete soil sampling. The work includes six soil borings to a maximum depth of 7 feet using Direct Push Technology (DPT) under challenging site conditions within a daycare playground canopy, with ancillary services encompassing utility location ($800.00 from GPRS), DPT drilling ($2,075.00 from Earth Tech Drilling), land survey services ($1,500.00 from Stoner & Associates), laboratory analysis, field expenses, and equipment rental. The final deliverable is due August 2, 2019, with the overall task completion date extended to December 13, 2019. Invoicing is contingent upon FDEP approval of the Natural Attenuation Monitoring and Soil Sampling Report with GIS/ArcDAPT deliverables.
