About this file

Written by GovTribe AI · May 30, 2025

These engineering design drawings detail a drainage infrastructure project for the West Abutment of the Garrison Dam in North Dakota, prepared by the U.S. Army Corps of Engineers Omaha District. The project involves installing a new 12-inch slotted C900 PVC drain pipe system along approximately 8,000 linear feet, with multiple pipe segments, cleanouts, and a new manhole (MH-3A) to manage groundwater drainage near the dam's west abutment.

The comprehensive set of technical drawings (16 sheets) includes detailed specifications for pipe installation, including precise elevation profiles, cross-sections, and geological considerations such as bank run gravel and 3A lignite layer management. Key technical elements include: 1) installing slotted pipes with fine and coarse filter aggregate, 2) maintaining proper pipe invert elevations ranging from approximately 1752 to 1760 feet NAVD88, 3) connecting to existing infrastructure like the concrete Flume No. 2, and 4) ensuring proper drainage while protecting existing dam safety instrumentation. The project is scheduled for March 2025, with a solicitation number W9128F25BA010.
