About this file
This is a bid package containing construction plans for the Lake Linden Trail Restoration project administered by the State of Michigan Department of Technology, Management and Budget, Facilities and Business Services Administration, Design and Construction Division, located in Hancock, Michigan. The plans document detailed civil engineering specifications for trail restoration work, including naturalization typicals, erosion and sediment control measures, and culvert repair and installation. The project scope encompasses multiple site locations along what appears to be a trail corridor, with specific attention to Quincy Creek culvert work involving both arch-top and box culvert installations, ranging from 24-inch to 5.5-foot wide structures. The plans include detailed cross-sections, elevation views, and construction notes for various downstream headwall configurations at multiple project sites, with specific elevation and dimension specifications provided for construction guidance.
The technical specifications indicate an assumed bearing capacity of 2,000 pounds per square foot for foundation work, with provisions for contractor notification to the engineer if unsatisfactory soil conditions are encountered during excavation. The plans specify geotextile liner placement requirements on all slopes prior to riprap installation, with payment for geotextile materials included in riprap costs. The contractor assumes sole responsibility for completing installation according to the design and construction drawings and for verifying site conditions prior to structure installation. The engineer disclaims responsibility for settlement, foundation failures, or installation deficiencies. The plans were prepared by OHM Advisors on behalf of the state and are dated November 7, 2022.
