About this file
This document is a specifications sheet for the Cottonwood Island Pile Dike System Repairs project on the Lower Columbia River in Cowlitz County, Washington, prepared by the US Army Corps of Engineers Portland District under Contract No. W9127N26BA005. The sheet details the timber pile and steel marker pile schedules required for the repair work.
The timber pile schedule specifies Douglas fir piles with a minimum 12-inch butt diameter, totaling 26 piles of 20-foot supplied length (520 feet total) and 96 piles of 25-foot supplied length (2,400 feet total). The steel marker pile schedule identifies 18 marker piles of varying sizes (12-inch, 16-inch, and 24-inch diameter with wall thicknesses of 5/8-inch and 3/4-inch) to be installed at specific dike structures, including enhanced enrockment offshore ends, offset pile dikes, and existing pile dikes. Each marker pile location is documented with embedment length, approximate mudline elevation, cut-off elevation (23 feet NAVD88 for all piles), and precise geographic coordinates (easting, northing, longitude, and latitude). Additionally, the contractor may install up to 18 steel mooring piles (24-inch maximum diameter) and 100 24-inch steel sheet piles at up to 3 material offload facilities (MOFs) for a total of 54 mooring piles and 300 sheet piles, with MOF piles restricted to vibratory installation methods. The contractor must account for additional pile length needed for cutoff allowances and mudline elevation variations of up to 3 feet.
