About this file
This is a Project Design Specifications document prepared for the City of Jackson Parks & Recreation Department for the Sharp Park Mountain Bike Trail Project in Michigan. The document outlines planning-level cost estimates for multiple trail development components across several project areas, including Sharp Park, areas adjacent to the MLK Equality Trail, the Armory Arts Walk, and Summit Township Trails. The Sharp Park project specifically encompasses approximately 12.5 miles of informally developed natural surface singletrack trails requiring design and construction services. The document provides detailed quantity breakdowns for various trail types and difficulty levels, ranging from easy trails to most difficult trails, along with supporting infrastructure such as kiosks, signage, mapping, and amenity facilities.
The total planning-level cost estimates for the Sharp Park project components are as follows: Trail Design and Construction costs total $434,579, while Sharp Park Other Amenities total $570,000, and trails adjacent to MLK Equality Trail total $353,648, Armory Arts Walk total $394,118, and Summit Township Trails total $282,892. Pricing is based on current market trends with unit prices ranging from $2.40 to $300,000 depending on the line item, and includes a 10 percent contingency across most project areas. The document notes that all pricing and quantities are subject to change upon completion of final design, and economies of scale may be realized through bundling design packages. Design estimates are dated between July 30, 2025, and August 11, 2025. Special amenity considerations include the use of repurposed shipping containers for trailhead and tool storage facilities as a cost-effective solution, with potential additional costs for licensed architect or engineer design services not included in current estimates.
