About this file
This document is a demolition plan for the Missouri River Project Office Asphalt Replacement project. The plan provides details for cold milling and full depth removal of existing asphalt and concrete pavement at specific locations within the project site. Work includes milling 2 inches of asphalt, removing chip seal, and cold planing or fully removing concrete pavement down to the subgrade in delineated areas. The plan also specifies protection of existing infrastructure to remain in place and repair of any incidental damage from demolition work. Notable demolition notes require conforming to specification section 32 01 16.71 for milling and planning, excavating subgrade in the northern full depth removal area as shown on plan CP301, adding grade rings and replacing manhole lids, and tapering milling near building faces to avoid removal directly abutting structures. The U.S. Army Corps of Engineers Omaha District issued the solicitation for the Missouri River Project Office Asphalt Repair project under number W9128F23B0019.
