This is a project photograph related to the County of San Mateo Parks Department's Flood Park Restroom A Sewer Line Replacement Request for Proposals. The image depicts the belly of a railroad line, showing the undersurface or lower section of railroad infrastructure, which may be relevant to site conditions or utility locating considerations for the sewer line replacement project at Flood Park.
The photograph appears to document existing site conditions or infrastructure that bidders should be aware of when planning the excavation, directional boring, or open trench installation methods for replacing approximately 130 linear feet of failing 6-inch vitrified clay pipe with new HDPE or PVC SDR 35 pipe. This visual documentation would be essential for proposers to understand potential conflicts with railroad infrastructure and associated safety and construction methodology requirements for the 60-day project completion timeline.
