Statement of Work For 6417 Epoxy Flooring Project May 2025

1.0 Contract Project: 6417 New Epoxy Flooring Installation

2.0 Location: USDA APHIS PPQ FO MFFRF

3.0 Project Background: Moore Air Base, building 6417 Mexican Fruit Fly Containment Lab (MFFCL), Mexican Fruit Fly Program’s overall goal is the eradication of Mexican Fruit Fly’s, (Anastrepha ludens) from the Lower Rio Grande Valley in Texas and the northern municipalities of Tamaulipas, Mexico. Eradication will be followed by the establishment and long-term maintenance of a functional barrier to keep these areas free of Mexican fruit fly.

The building 6417 building floors are dilapidated due to high personnel traffic, corrosive chemical washout, foundation settling, and equipment.

A new epoxy floor is critical to minimize the porous and cracked surfaces that collect the washout of Mex-fly rearing ingredients, causing mold and bacteria that affects or kills off the sensitive Mex-Fly larvae, resulting in loss of expensive production funded by commercial industry stakeholders.

4.0 Scope:

4.1 Affected Areas:

Solicitation 12639525Q0207, Attachment 1

4.2 New Epoxy Floor Install: Remove, prepare, and install the new epoxy flooring section areas one at a time to allow existing equipment to be moved for the new floor epoxy floor.

The Mex-Fly Containment Lab is a quarantined facility and will continue to operate simultaneously with this operation. Careful consideration for areas that are restricted and contained are mandatory along with the proper use of the proper PPE required to be within the building.

4.2.1 Floor Preparation: Demolish and remove the existing (approximate) 1,200 sq. ft., 6” X 6” floor tiles that includes a wall splash of (approximately 163 LF), 6” high, along the general work area, masking areas off with plastic and tape. Diamond grind floor to new epoxy manufacturers recommended CSP level. Etch prep floors. Clean, dry, and vacuum area. Conduct a moisture test for dryness.

3. Address Surface Profiling for Cracks and Holes: Fill any cracks, holes, or uneven areas with a suitable concrete filler or epoxy putty.

4. Grinding: Use a floor grinder to create a rough surface profile for the epoxy to adhere to, especially if there are existing coatings or unevenness.

5. Acid Etching: Apply a diluted acid solution to etch the concrete surface, opening the pores for better epoxy adhesion.

6. Dust Removal: After any surface profiling, thoroughly sweep and vacuum to remove any dust or debris.

7. Apply Primer: Apply a primer that’s compatible with the epoxy system you're using to improve adhesion and ensure a smooth surface.

8. Protect Walls and Edges: Mask or cover walls, doors, and any other areas you don't want to get epoxy on.

9. Ensure Proper Ventilation: Ensure adequate ventilation during epoxy application, especially if using solvent-based epoxy.
