8) Supplemental Attachment to TE1_04.24.2025.pdf

This document is a supplemental attachment detailing water service line replacement specifications for multiple buildings at Goodfellow Air Force Base in San Angelo, Texas. The attachment provides detailed mapping and specifications for water service line replacements at three locations:

1. Building 241: A 4-inch steel galvanized water service line, 47 feet long, buried at 30 inches depth with a 4-inch valve.
2. Building 251: A 6-inch PVC water service line, 200 feet long, buried at 56 inches depth with a 6-inch valve.
3. Building 700: A 4-inch copper water service line, 9 feet long, buried at 75 inches depth with a 4-inch valve.

The images include aerial maps with blue utility line markings and red-circled areas indicating the specific excavation and replacement zones for each building. There is also a notation for a valve replacement on the West Side of a New PT Pad, though specific valve size and depth are not specified. These details align with the broader solicitation for replacing water service lines at various base locations, emphasizing the need for lead-free materials and modern plumbing infrastructure.
