The City of Ames is accepting proposals from qualified firms for Engineering and Design Services for Ada Hayden Heritage Park Path Replacement Project for the Parks and Recreation Department. The project involves the removal of the ten-foot-wide hard surface asphalt (HMA) trail at Ada Hayden Heritage Park and replacing it with a twelve-foot-wide concrete surface (PCC) trail. Total path length that will be replaced is approximately 3.1 miles. The goals of the project are to alleviate safety concerns due to path degradation (sloughing, cracking, vegetation) and improve circulation by adding striping and signage for patrons. SCOPE OF SERVICES • Facilitate project kickoff meeting to understand expectations for the project including but not limited to project goals, schedule, budget, and deliverables. • Attend regular meetings with City staff to discuss progress, review drawings and specifications, resolve issues, and adjust project scope as needed. • Conduct a detailed site visit to assess existing path conditions including path deterioration and subgrade stability. • If deemed necessary, perform site topographical surveys documenting existing grades, elevations, and drainage patterns, utilities, and other important features related to the project. (Original construction plans are available) • Develop design plans and specifications for the demolition, removal, and construction of a new twelve-foot wide concrete (PCC) path with appropriately sized turf (type 1) shoulders. • Identify if current asphalt can be reused as subbase for the new path • Identify and design necessary drainage improvements to prevent future damage to the path from water or erosion. • Ensure that the path is designed to meet local, state, federal laws like ADA (Americans with Disabilities Act) accessibility requirements, City of Ames Supplementary Specifications, and SUDAS. • Provide detailed specifications for concrete mix design, subbase materials, and any other materials to ensure long lasting performance and compliance with local standards. • Include provisions for erosion and sediment control during construction. • Specifications shall include detailed quantity takeoffs for all materials.
