Surface Flatness: Deviation not to exceed ¼ inch in 10 feet in any direction, as verified by a straightedge test.

Structural Integrity: No visible cracks, spalling, or surface delamination. Concrete shall exhibit no signs of movement or instability under foot tra ic or equipment load.

Surface Cleanliness: Pad must be clean, dry, and free of loose debris, oil, grease, sealers, or contaminants prior to installation.

Moisture Tolerance: Moisture content of the slab shall not exceed 5% by weight (as measured by a concrete moisture meter) if adhesives or infill require it.

Drainage: Installation shall ensure adequate drainage to prevent water pooling, compliant with site-specific requirements.

2.4.3. If any of the conditions in 2.4.2 are not met, the contractor shall notify the Government prior to proceeding.

3. PERFORMANCE STANDARDS:

3.1. The installed turf system (turf, padding, infill) shall meet the following performance standards:

3.1.1. Durability: Withstand heavy foot tra ic and outdoor weather conditions for a minimum of 5 years.

3.1.2. Maintenance: Require minimal maintenance, with the contractor providing a maintenance guide outlining care procedures.

3.1.3. Coe icient of Friction: Provide a minimum coe icient of friction of 0.6, measured per ASTM F2333, to ensure adequate traction.

3.1.4. Vertical Load: Withstand vertical loads of at least 75 psi without permanent deformation, verified via ASTM D3574.

3.1.5. Drainage Rate: Facilitate drainage at a minimum rate of 10 inches/hour, tested per

ASTM F1551.

3.1.6. Fiber Retention: Maintain a minimum of 95% fiber retention and structural integrity after simulated wear equivalent to 10 games, using ASTM F1015 protocols.

3.1.7. Impact Attenuation: Meet or exceed ASTM F1936 standards for impact attenuation (Gmax ≤ 200).

4. INSTALLATION REQUIREMENTS:

4.1. Timeline:

4.1.1. Installation shall be completed within 60 calendar days from contract award.

4.1.2. The following conditions will be considered "weather delay days" and shall not count toward the 60-calendar-day completion period:

Precipitation exceeding 0.10 inches in a 24-hour period (measured on-site or by the nearest NOAA-certified station);

Sustained wind speeds above 20 mph or gusts over 30 mph, where wind-sensitive operations are involved (e.g., turf laying, adhesive application);

Ambient temperatures below 40°F (4.4°C) or above 95°F (35°C) when such conditions prevent adhesive curing or safe equipment operation.

Snow cover, standing water, or saturated subgrade conditions that render the site unworkable for turf installation or heavy equipment.

4.2. Site Access: Contractor shall coordinate with base personnel for site access and security requirements.

4.3. Quality Control (QC):

4.3.1. The contractor shall submit a Synthetic Turf Quality Control Plan (QCP) within 10 calendar days of contract award. The QCP must address the following, with supporting documentation:

4.3.2. Inspection and Testing Schedule: Provide a timeline identifying inspection and testing checkpoints for:

Subgrade preparation and compaction

Aggregate base installation (gradation, depth, compaction)

Turf roll layout and seaming

Infill material installation (depth, distribution)

Final grooming and field markings

4.3.3. Testing Procedures and Standards: All testing must be performed by qualified personnel and reference the following minimum standards:

Base Compaction: ASTM D1557, min. 95% Modified Proctor

Permeability: ASTM F2898 (entire system) or ASTM F1551 (turf only)

Impact Attenuation (Gmax): ASTM F1936, ≤ 200 Gmax

Infill Depth and Uniformity: Spot checks every 500 ft², within ±3 mm tolerance

Seam Strength: ASTM D5034 or equivalent, ≥ 40 lb/in

Turf Roll Alignment: ±½ inch per 20 feet tolerance

Rotational Resistance: ASTM F3189 if required by spec

4.3.4. Personnel and Responsibilities: Identify QC personnel (by name, title, certifications) responsible for inspections and documentation. QC sta must be independent of the installation crew.

4.3.5. Reporting Requirements: Submit weekly QC reports, documenting:

Tests conducted, results, and pass/fail criteria

Photos of work progress and completed tests

Maintain a complete QC log available on-site at all times.

4.3.6. Nonconformance and Corrective Action: Any deficiencies shall be corrected within 3 working days. Retesting is required at contractor’s expense for all failed areas before proceeding.

Inspection procedures to identify wear, seam separation, or infill displacement

Recommended equipment (with manufacturer specifications)

5.3.2. Delivery Format:

In-person presentation or live demonstration on the actual field

Printed or digital maintenance manual provided to all attendees
