West Pass Track Switch Retaining Wall Repair

The West Pass Track Switch Retaining Wall Repair project at Railtown 1897 State Historic Park in Tuolumne County, California, involves stabilizing and reconstructing a deteriorating retaining wall to improve safety and compliance for train crews and walkways adjacent to the tracks. The work includes reinforcing the existing wall structure, replacing damaged switch ties and headblocks, and constructing a new retaining wall using non-serviceable railroad ties secured by driven boiler tubes for added stability. Tamped and compacted ballast will be installed between the wall and the track to ensure proper support and long-term integrity. The project is categorized under NAICS code 238140 for site preparation and is managed by the California Department of Parks and Recreation, with no formal solicitation number or contract value provided, indicating it is a forecasted action pending final procurement. Inspection and acceptance will occur on-site at the park, with compliance guided by state environmental exemptions CCR §15301 and §15304 for minor alterations and maintenance of existing facilities, though no specific engineering standards are cited. Primary point of contact is Andrew Collum, Environmental Scientist, reachable via phone or email, with secondary oversight from District Superintendent Danielle Gerhart. There is no indication of a formal contract type, evaluation criteria, payment details, invoicing method, or required representations from offerors, and the project lacks detailed financial, scheduling, or special requirements provisions typically found in full procurement documents.
