About this file

This is a site layout and details drawing for Deep Well 51 at the U.S. Army Garrison – Rock Island Arsenal in Rock Island, Illinois, prepared by the Directorate of Public Works. The drawing, issued January 9, 2025, with project number 2026-0215, was designed by C. Hawkinson, checked by S. Bach (Chief of Engineering), and approved by G. Koski (Director of Public Works).

The document presents two primary sections: a well sealing detail on the left showing cross-sectional specifications for the deep well with multiple level designations (surface level at elevation 631 feet, extending downward through various grades), and a project location map on the right identifying the well's position relative to North Avenue and nearby buildings (50, 52, and 71). The well sealing detail includes specifications for neat cement placement, bentonite slurry placement, disinfected clay/gravel placement, and a rug and seal installation, with corresponding elevation markers and grade transitions noted throughout the well's depth. The project location photograph provides aerial context showing parking areas, buildings, and the specific geographic placement within the garrison facility. The drawing is marked as 1 of 1 and designated as sheet C.01.
