Preliminary Engineering Design (30% Design) for Trail Infrastructure

The contract involves the development of 30 percent preliminary engineering designs for two critical trail infrastructure components: the relocation of trailhead parking and the design of a resilient pedestrian bridge over Bull Run Creek, located outside the 100-year floodplain. The work requires detailed alignment planning and selection of appropriate materials to ensure durability, safety, and environmental compatibility. This phase of engineering will establish the foundational design parameters necessary for future construction, including site constraints, structural requirements, and integration with existing trail systems. The project aims to enhance public access and improve resilience against natural elements while minimizing disruption to the surrounding ecosystem. This subcontract is issued under the NAICS code 541330 for architectural and engineering services and is administered by the Sierra Nevada Conservancy in California. The solicitation was posted on June 8, 2026, and the performance location is tied to the Bull Run Creek area, though specific city or zip details are not provided. The contract is part of broader efforts to upgrade outdoor recreation infrastructure in the region, with designs intended to meet long-term operational and environmental performance standards. All work must align with state and federal guidelines for trail development and floodplain management, even though the bridge is situated beyond the 100-year floodplain.
