SECTION 3

REQUIREMENT AND SCHEDULE:

Technical issues will be addressed by the Project Manager, Gregg Roberts at 813-612-3687 or gregg.roberts@aptim.com.

General

1. Drilling locations have the potential for exposure to chlorinated solvents. Assume Level D PPE, with APTIM conducting health and safety monitoring.

2. Sunshine Utility mark outs must be requested and performed prior to the work being performed.

In addition, the drilling contractor will also hand auger each location to a depth of 10 feet or to refusal (but not less than 5 ft bls) below the surface to check for utilities.

3. Property access arrangements will be made by APTIM. However, the drilling contractor is responsible for any necessary State or Local drilling permits, including Water Management District requirements.

4. The drycleaning facility was located within the Forest Center Shopping Plaza in the last space on the east side of the single story business strip. Working areas will be extremely restricted due to the site parking limitations, brush, landscaping, and an active delivery alleyway. Water and electricity may not be available during the work. APTIM will have more information regarding access to water and power before the work begins.

5. Drillers are to provide and utilize safety vests and cones in pedestrian, active parking and vehicle traffic areas. Some of the work will be performed within an alley easement, and possibly on adjacent properties.

6. Drilling equipment must be properly decontaminated between locations in accordance with FDEP 2017 DEP-SOP-001/01 Standard Operating Procedures for Field Activities procedures.

7. Driller to provide NEW 55-gallon drums for all IDW containment (decon fluids, soil, and groundwater purge water). At the end of the project, all drums are to be consolidated to one location, likely to be located at the southeast corner of the property.

18. Approximate start and completion date of the project is August 2023.

Specific:

The site location:

The former Forest Cleaners was located at the east end of the Forest Center Shopping Plaza in Silver Springs at 15912 East Highway 40 in Marion County, Florida. The space is currently vacant.

The former Forest Cleaners facility appears to have operated within the space from December 1992 to 2011, approximately 19 years.

The property was originally developed in 1986.

The former Forest Cleaners was accepted into the Drycleaning Solvent Cleanup Program in 1998 under FDEP Facility Identification Number 429500885 (now listed as ERIC_4907). The work is being performed for the FDEP Waste Cleanup Section.

Scope-of-Work: For bidding purposes, please consider the following scope of work for the site:

1. Advance two (2) Lithologic Cores:

a. Installation of two (2) continuous soil cores by direct push to 60 ft bls (or first refusal). The Macro cores will be installed to identify the depth to groundwater and log the lithology at the boring location. Upon completion of the lithologic core, the borehole must be properly abandoned by tremie-grouting the hole under pressure from the bottom to the surface. The approximate proposed location of the DPT lithologic core is shown on the attached figure.

2. Installation of three (3) Shallow Piezometers:

a. Utilize 3 1/4 inch OD or equivalent rods

b. 1-inch diameter, schedule 40, PVC well riser and 0.006” slotted screen installed to a total depth of 15 feet bls (or shallower, dependent on the depth to groundwater).

c. 10 feet Pre-Pak Well Screen with a 30/65 grade sand pack.

d. Flush-threaded PVC bottom caps and well riser piping.

e. Allow for borehole collapse to top of screen at 5 feet bls, then place silica sand seal (30/65 grade or equivalent) to 4 ft bls.

f. Grout borehole to within 0.5 feet bls

g. At surface, flush, 8-inch diameter steel bolt-down manhole set in high strength 2ft x 2ft concrete, pad with water-tight expandable plug well seal.

h. Please utilize a wood frame for the construction of the manhole pad, if not within concrete or asphalt.

i. The piezometers will require development by rigorously over-pumping and surging.

j. Consolidate IDW to an area on south side of the Property at a designated area for future characterization, removal and disposal.

k. The proposed locations for the three (3) Piezometers are shown on the attached figures.

3. Outdoor DPT Groundwater Sampling (Exterior):

a. Nine (9) outdoor DPT groundwater locations are proposed within the parking areas and offsite surrounding the former cleaners. Three (3) screen point groundwater samples will be collected from each location at approximately 15, 25, and 35 ft bls for the collection of a groundwater samples.

b. All bores, including DPT groundwater locations will be properly abandoned by tremie-grouting the hole under pressure from the bottom up.

c. Please include all equipment and supplies, pumps, tubing, foot valves, connectors and miscellaneous materials necessary for the collection of the groundwater samples. Sample containers will be provided by the laboratory.

d. The proposed locations for the DPT groundwater sampling are shown in the attached figures.

4. Additional Monitoring Well Installations (Separate Mobilization):

a. Note that the installation of wells will be performed separately from the DPT groundwater sampling, therefore, the Driller should include a separate mobilization for the well installations.

b. After conferring with the FDEP, the quote should include the installation of three (3) additional shallow wells and one (1) deep monitoring well.

c. The shallow wells will be installed similar to the piezometers, utilizing a direct push drilling rig.

The shallow wells will also be similarly constructed of 1-inch diameter PVC with 10 feet of fine mesh pre-pack 0.006-inch slotted screen with a 30/65 sand pack and installed to a 15 ft total depth or shallower, dependent on the depth to groundwater encountered at the site. The wells will also be flush mounted within 8-inch diameter steel bolt-down manholes.

d. The deep well will also be installed by direct push to an estimated total depth of 35 ft bls. The well will be constructed of 1-inch diameter PVC with 5 feet of fine mesh pre-pack 0.006-inch slotted screen with a 30/65 sand pack installed from 30 to 35 ft bls. A two to three foot fine silica sand seal will be installed above the screen and the remaining annulus will be tremie grouted to just below the surface. The deep well will also be flush mounted within 8-inch diameter steel bolt-down manholes.

e. The location of the final wells has not determined at this time.

Please call Gregg Roberts at (863) 670-0215 should you have any questions.

Provide the following:

1. All bidders please include the make and model of the rig intended to perform this scope-of-work.

2. Note that the actual construction and depth of the shallow wells will be dependent on the depth to shallow groundwater determined in the field.

3. Also note that all IDW will need to be consolidated to a designated area for future characterization, removal, and disposal.

3. All bidders please include an estimated number of drums in their bid.

4. All bidders please include an estimated time required to complete the scope at the site.

5. Please provide an all-inclusive price quote by close of business Wednesday, May 31, 2023, if possible.
