Proposal for Pre-Construction Activities Plan Alpine Dry Cleaners Inc | Gainesville, FL | ERIC_3987 September 5, 2025 | Terracon Proposal No. PEQ257424

PROJECT BACKGROUND

Site assessment activities conducted in 2023 and 2025, which included Modified Active Gas Sampling (MAGS), indicated the presence of tetrachloroethene (PCE) impacts in soil gas and groundwater, as summarized in the Site Assessment Report (SAR), dated January 30, 2024, and the Supplemental Site Assessment Report (SSAR), dated February 14, 2025.

On June 30, 2025, Terracon submitted an ISRP providing the design basis to implement a soil vapor extraction (SVE) system to reduce the mass of volatile organic halocarbons (VOHs) within the vadose zone.

Terracon has prepared this proposal to initiate the construction plans to implement the SVE system.

SCOPE OF SERVICES

The proposed scope of work consists of the following subtasks:

Subtask 1 Project Management

Costs associated with this subtask are directly computed. Donna Cline will be the Project Manager.

Subtask 2 Pre-Construction Activities Plan (PCAP)

The PCAP will be prepared according to the design specifications described in the ISRP, and per any comment revisions requested by the FDEP. The proposed SVE wells will be installed from existing MAGS wells if they are in good working condition at the time of construction.

Two new SVE wells are proposed adjacent to the interior building well to minimize disruption to the building the operations as a photography studio.

This subtask will include:

Logistics required to transfer the SVE system from Palace Cleaners.

Bid preparation and recommendation to general construction subcontractor.

Site visit with general construction subcontractors, property owners, and FDEP.

Updated construction plans, based on site visits and discussions with subcontractors, property owner, and FDEP.

Review and select the lowest bid and responsive remedial subcontractor.

Prepare the cost estimate to include system procurement, installation/construction, startup, one quarter of operation and maintenance, and a Construction Completion Report.

Prepare the estimated schedule.
