About this file
This is an engineering drawing (C902) showing civil details for a steam tunnel construction project at a VA facility in Des Moines, IA. The drawing is dated August 9, 2024, and is part of the 100% Final Bid Documents package.
The drawing includes detailed cross-sectional views and specifications for the steam tunnel construction, including typical tunnel cross sections, rip rap details at flared end sections, and water main crossing details for both overhead and floor configurations. Key technical specifications show a tunnel with varying depths of 6.5' to 8.0', incorporating 4" perforated HDPE drain tile, geofabric layers, crushed stone (3/4" to No. 4 per ASTM D448), and a 12" clay cap with restored surface. The water main crossings detail connections to existing 10" and 6" DIP watermains using various DIP bends (11-1/4° and 45°). The drawing includes specific measurements, elevations, and construction requirements for proper installation and waterproofing. Anderson Engineering of Minnesota, LLC is listed as the designer of record.
