17264 Cheboygan Lock Downstream Wall - Historical Geotechnical Explorations.pdf

This document is a set of engineering and construction planning drawings for the Construction of Bin Wall Wharf project by the State of Michigan Department of Natural Resources Waterways Division, located at the Cheboygan Lock and Dam complex. The project involves detailed site plans, soil boring logs, and technical specifications for a complex riverine infrastructure improvement, specifically focusing on the Cheboygan River and surrounding Great Lakes Tissue Company property. The plans include multiple site layouts, proposed preliminary site plans, detailed boring logs for various test locations, and specific engineering details for new timber piling and structural elements.

The project documentation includes comprehensive geological surveys with detailed soil stratification data from multiple boring locations, indicating thorough geotechnical investigation of the site. The project benchmark elevation is set at 596.44 (1985 NGVD), and the plans show intricate details of existing and proposed structures, utility lines, and river morphology. The technical drawings are dated with a final revision on 4/25/94, suggesting this is a mid-1990s infrastructure development project, and they were prepared by JDA Design Group, as indicated by the engineering firm's logo on the documents. The drawings provide extensive technical information about soil composition, structural requirements, and precise geographic positioning of proposed construction elements.
