About this file
This is a Statement of Work (SOW) for asphalt parking lot sealcoating and striping services at the USDA-ARS-BIIRU facility located at 501 South Chapel Street, Newark, Delaware 19713. The project objective is to restore, protect, and restripe an existing 9,000 square foot asphalt parking lot to extend its lifespan, improve visual appeal, and ensure compliance with local accessibility guidelines. The contractor must provide all labor, materials, equipment, and supervision to complete four phases of work: Phase 1 involves surface preparation including debris removal via power-blowing and sweeping, oil spot treatment with specialized chemical primer, and vegetation clearing; Phase 2 requires crack sealing through routing and application of commercial-grade, hot-pour rubberized crack sealant to cracks measuring 1/4 inch or wider; Phase 3 specifies application of two uniform coats of premium commercial-grade asphalt emulsion sealer mixed with silica sand, with the first coat applied via squeegee for deep penetration and the second coat via spray; and Phase 4 involves restriping the parking lot to the original layout with twenty-one standard-sized parking spaces and one ADA-compliant handicapped space using high-durability, DOT-approved traffic paint in white or yellow.
The project will be executed over a one-day period, ideally on a weekend to minimize business disruption, with the parking lot remaining closed to vehicle traffic for a minimum of 24 hours after final coat application. The contractor is responsible for supplying and installing traffic control barricades, protecting adjacent surfaces from overspray or tracking, and removing all trash and debris daily. Acceptance criteria require a uniform matte-black sealcoat finish with no streaks or uncovered spots, straight and sharp parking lines with uniform 4-inch width, and ADA-compliant handicapped space dimensions and visual requirements.

Phase 1: Surface Preparation
• Debris Removal: Power-blow and sweep the entire 9,000 sq. ft. surface to remove dirt, gravel, and oil.
• Oil Spot Treatment: Apply a specialized chemical primer to oil, grease, and gas stains to ensure sealcoat adhesion.
• Vegetation Clearing: Remove all weeds and grass growing in asphalt cracks or edges.
Phase 2: Crack Sealing
• Routing: Clean out debris from cracks measuring 1/4 inch or wider.
• Filling: Apply commercial-grade, hot-pour rubberized crack sealant to prepared cracks.
Phase 3: Sealcoat Application
• Material: Use premium, commercial-grade asphalt emulsion sealer mixed with silica sand for slip resistance.
• Application: Apply two (2) uniform coats of sealer.
• Method: Apply the first coat via squeegee for deep penetration and the second coat via spray for a smooth finish.
Phase 4: Line Striping and Layout
• Layout: Restripe the parking lot exactly to the original layout.
• Standard Spaces: Paint twenty-one (21) standard-sized parking spaces using high-durability, DOT-approved traffic paint (White or Yellow).
• Handicapped Space: Paint one (1) designated accessible parking space including standard white/yellow boundary lines, a blue background box, and the international symbol of accessibility (wheelchair icon).
3. Timeline and Schedule
• Work Window: The project will be executed over a one-day period, ideally over a weekend to minimize business disruption.
• Curing Time: The parking lot must remain completely closed to vehicle traffic for a minimum of
24 hours after the final coat is applied.
4. Contractor Responsibilities & Logistics
• Barricading: Supply and set up traffic cones, caution tape, and barricades to block off the work zone.
• Overspray Protection: Protect adjacent sidewalks, concrete curbs, landscaping, and structures from sealcoat overspray or tracking.
• Clean-Up: Remove all trash, empty material containers, and debris from the site daily.
5. Acceptance Criteria
• The cured sealcoat must show a uniform, matte-black finish with no streaks, or uncovered spots.
• All parking lines must be straight, sharp, and uniform in width (typically 4 inches).
• The handicapped space must meet local ADA layout dimensions and visual requirements.
