Johnson Field Repair

STATEMENT OF WORK REFURBISH JOHNSON SOFTBALL FIELD B1883 TRAVIS AFB CALIFORNIA Base Project Number: XDAT 26-1028 DATE: 24 August 2026 BACKGROUND The primary driver of this project is a severe safety hazard: extensive gopher infestations have created a network of subsurface voids and surface holes across the playing area resulting in an uneven, hazardous field that risks serious player injuries (e.g., ankle sprains and falls). This Statement of Work (SOW) defines the requirements for the complete design-build refurbishment and renovation of the grass turf, subsurface gopher barrier, in-ground irrigation system at Johnson Softball Field (Facility #1883). An uneven field, or damaged equipment increases the risk of player injury. INTRODUCTION The project site is located at the Johnson Softball Field, Facility #1883, on Burgan Boulevard, Travis AFB, California (directly across the street from base lodging and south of the Dining Facility/DFAC). The contractor shall provide all labor, materials, equipment, permits, clearances, engineering/design services, transportation, traffic control, and supervision necessary to deliver a complete and usable athletic facility. The scope combines comprehensive civil, agricultural, irrigation tasks. The final product must fully restore the field's playing surface, establish a robust subterranean pest barrier, modernize the facility's utility and structural support networks, and meet all applicable Unified Facilities Criteria (UFC) standards.

REPAIRS: Contractor shall: Rototill the existing turf, eradicate gopher holes, backfill burrow networks. Applicable Codes & Standards: UFC 3-201-02 – Landscape Architecture. Level and Grade Johnson Field for Improved Drainage: Regrade field surface to establish positive surface drainage away from playing areas. Submit drainage plan for government approval. Applicable Codes & Standards: UFC 3-201-01 – Civil Engineering; IBC Chapter 18 – Soils and Foundations / Site Grading Install Subsurface Pest Barrier (Gopher Wire Mesh): Supply and install a continuous subterranean pest barrier directly beneath the seeding/turf root zone across the entire athletic field playing surface footprint (~72550 sf) prior to final turf/seeding establishment. Material Specification: Type 304 Stainless Steel Welded Wire Mesh (Hardware Cloth) conforming to ASTM A1022 or ASTM A580. Wire Gauge: 18 AWG (American Wire Gauge) heavy-duty stainless-steel wire. Mesh Opening: 1/2 in x 1/2 in square mesh opening (or 3/4 in x 3/4 in maximum opening) to prevent burrowing penetration while ensuring unrestricted root growth and water drainage. Installation Standards: Lay mesh panels flat across level subgrade with a minimum 6-inch overlap on all seams. Secure all seams and perimeters of the mesh panels to the subgrade using 6-inch 11-gauge galvanized or stainless-steel landscape staples spaced maximum 18 inches on center. Extend mesh a minimum of 12 inches up perimeter fence footing borders or landscape headers to prevent edge bypass. Cover mesh with a 1-inch to 2-inch buffer layer of topdressing soil prior to seeding placement. Provide full UFGS specifications, structural/fastening details, and layout. Applicable Codes & Standards: UFC 3-201-02 – Landscape Architecture; ASTM A1022 or ASTM A580 Seeding: Upon completion of all groundwork the contractor shall seed the topsoil in the existing turf area. Establish a minimum 95 percent uniform ‘stand of turf’ in accordance with Section 32 05 33 (Landscape Establishment). Contractor is responsible for growth of ground cover until maturation.
