STATEMENT OF WORK

JCGU 21-7001 Repair Griffin Avenue

This Statement of Work (SOW) defines the requirements for construction services for “JCGU 21-7001 Repair Griffin Avenue” located at Goodfellow AFB, TX. The work covered by this SOW consists of furnishing all labor, equipment and material, and performing all work in accordance with specifications and drawings, and subject to the terms and conditions of this contract.

The following work items are hereby modified as follows:

Description:

Statement of Work, dated 2/12/2026

a. DELETE: Paragraph 2.1.2 -TRAFFIC WARNING FOR PEDESTRIAN CROSSING SIGNAGE: The system shall automatically activate a visual warning to drivers when a pedestrian is detected approaching or entering the crosswalk. The system and all its components must be compliant with the latest edition of the Manual on Uniform Traffic Control Devices (MUTCD). The system shall utilize a passive pedestrian detection system consisting of two bollards spaced for a marching formation to pass through. All system components (detection bollards, signs, and flashing beacons) shall communicate wirelessly, eliminating the need for trenching or physical wiring between components. Upon pedestrian detection by the bollard system, the LED-flashing border signs shall immediately begin to flash. The flashing shall continue for a pre-programmed and field-adjustable duration, sufficient for a group of pedestrians (march formation) to cross the entire street at a normal walking speed or ~3.5 feet per second.

b. ADD:
