About this file
This document is a drawing index and survey control sheet for the Conemaugh River Lake Accumulated Sediment Dredging Project (Solicitation W911WN25BA013). The sheet provides comprehensive technical details including key project elevations ranging from the concrete dam crest at 985.9 feet to the streambed at 848.9 feet, and a detailed survey control table with 15 geographic control points using Pennsylvania State Plane coordinate system and NAVD88 vertical datum. The drawing index lists multiple sheets covering general conditions, civil engineering plans, dredging templates, and site-specific documentation, with reference to historical as-built drawings from previous flood control and infrastructure projects in the area.
The document includes critical project notes specifying environmental and operational constraints, such as tree clearing restrictions for bat conservation (September 1 to March 31), requirements for utility location notifications, wetland area restoration protocols, and survey control point specifications. The project involves dredging accumulated sediments in the Conemaugh River Lake, constructing a Dredged Material Management Area, and completing associated site restoration work, with a projected completion timeline of 685 calendar days after the Notice to Proceed. The procurement is structured as a 100% Small Business Set-Aside with an estimated contract value between $10-25 million under NAICS code 237990.
