About this file
This is a preliminary architectural drawing set issued by the State of Michigan Department of Technology, Management and Budget, State Facilities Administration, Design and Construction Division, for the Michigan Department of Natural Resources. The project involves the renovation of a universal access path at Muskallonge Lake State Park located at 29881 Cord 407, Newberry, Michigan 49868. The drawings depict structural details for the renovation of a stairway including foundations, boardwalk framing, railings, and overpasses designed to meet ADA accessibility requirements. The design includes multiple foundation types: 114 total 18" x 18" concrete foundations, 12 total 24" x 18" concrete foundations for double posts at corners, 5 helical piles with 24" concrete pier caps at corners, and 23 standard helical piles with 18" x 18" concrete pier caps. The construction incorporates pressure-treated Southern Pine wood components, Simpson connectors, welded steel handrails, and fiberglass grating or wood decking. The drawings are marked as preliminary and not for construction, dated April 25, 2024, prepared by OHM Advisors Architects Engineers Planners, and are part of bid set 751.22438.ABG.
The drawings contain no information regarding pricing terms, set asides, contract incumbents, funding sources, or award dates as this is a design document rather than a formal bid solicitation or contract award notice. The structural plans are protected by copyright and may not be duplicated, distributed, or disclosed without prior written consent of OHM Advisors and the client. All wood materials are specified as pressure-treated (UC4A) Southern Pine Grade 2 or better, with vertical helical piles designed for allowable loads of 6 kips and ultimate loads of 18 kips at minimum tip depths of 15 feet or bedrock. The design includes specific requirements for post bracing in both directions where post heights exceed 10 feet, with maximum spacing of 10 feet between bracing centers, and detailed specifications for foundation ties, railing connections, and landing framing to ensure structural integrity and accessibility compliance.
