About this file
This is a bid package document prepared by the State of Michigan Department of Technology, Management and Budget, Facilities and Business Services Administration, Design and Construction Division, for the Lake Linden Trail Restoration project (Project No. 7136-20-0040). The plans detail civil construction specifications and site details for trail restoration work located in Hancock, Michigan. The document includes technical drawings prepared by OHM Advisors (Architects, Engineers, Planners) dated November 8, 2022, and presents detailed design specifications for multiple construction elements including proposed culvert installation, culvert profile and section details, naturalization typicals with existing removal plans, earth diversion berms, check dams, riprap slope treatments, silt fence installation, sediment traps, rock-lined channels, vegetation buffer zones, slope benching, plunge pools, and trail section specifications. The plans specify a 14-foot-wide trail corridor with 20-foot clearance requirements and include detailed inlet and outlet specifications for an existing culvert structure measuring 8.0 feet by 8.0 feet, with provisions for hand chipping, patching with mortar or concrete, epoxied dowel installation at 24-inch intervals, and a minimum 4-inch concrete floor overlay with wire fabric reinforcement.
The technical specifications emphasize erosion control and water management measures, including requirements for MDOT plain riprap application on slopes of 10% or less or in areas with stream velocities of 10% or greater than 5.5 feet per second. The plans incorporate both permanent and temporary soil stabilization features, with specific notes regarding check dam depth limitations and their impact on ditch flow characteristics. All work is subject to call-before-you-dig requirements and underground utility location protocols. No pricing, contract term, award dates, or bidding response deadlines are specified in this plans document; these details would typically be contained in separate solicitation documents or bid instructions accompanying this technical package.
