About this file
This document is a demolition plan for asphalt replacement work at the Missouri River Project Office in Omaha, Nebraska. The plan details areas where existing asphalt, concrete, and other pavement materials will be cold milled, chip sealed surfaces will be planed and milled, and some areas of full depth removal down to the subgrade. Notable demolition tasks include protecting existing utilities and structures to remain in place, adding grade rings and replacing lids on sanitary sewer manholes, and tapering milling at building interfaces. The related federal contract opportunity is solicitation number W9128F23B0019 issued by the U.S. Army Corps of Engineers Omaha District for asphalt repair work at the Missouri River Project Office, with responses due on or before September 15, 2023.
