Attachment_F_-_As-Built_Information.pdf

This is an as-built information document for the 18-Inch Sewer Replacement Project in California, detailing surveyed manhole locations and specifications for an existing sewer infrastructure system. The document provides technical data on eight monitored manholes along an 18-inch sewer bypass line, including manhole identification numbers, depth measurements ranging from 8.1 to 11.5 feet, rim elevations between 466.2 and 468.77, and precise geographic coordinates (Point_X and Point_Y) for spatial reference. The file references File Drawings 2-025 and 2-062 for sewer detail maps and includes a comprehensive manhole information table identifying specific infrastructure points such as 10J-M035, 10J-M025, 10I-M035, and others that will serve as reference points for the proposed project work.

This as-built documentation supports the engineering design phase of the 18-inch sewer replacement project, which involves abandoning an existing 18-inch cast iron pipe crossing beneath Union Pacific Railroad corridors and constructing a new 18-inch gravity sewer alignment outside the railroad right-of-way. The surveyed data and manhole specifications contained in this attachment are essential baseline information for the consulting firm selected to perform hydraulic evaluation, engineering design, preparation of Plans, Specifications, and Estimates (PS & E), and construction support services. This technical reference material enables accurate assessment of existing facilities and informs the design decisions required for manhole modifications and new sewer facility configurations throughout the project scope.
