STATEMENT OF WORK

REFURBISH JOHNSON SOFTBALL FIELD B1883

TRAVIS AFB CALIFORNIA

Base Project Number: XDAT 26-1028

DATE: 24 August 2026

1. 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.

2. 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.
