3- Highway 30 Record Drawing 26V-92.pdf

This is a record drawing document for Highway 30 related to the City of St. Helens' Wastewater System Capacity Improvements Project in Oregon. The drawing serves as a reference document for the construction and replacement of sanitary sewer infrastructure within Basins 4 and 6, illustrating the existing pipeline layout, connections, and system configuration along Highway 30. The record drawing provides detailed mapping of the wastewater collection system in the project area, identifying key infrastructure elements and their spatial relationships to support project planning, design, and construction activities. This technical drawing is essential for contractors and engineers to understand the current system conditions and existing conveyance infrastructure that will be modified or replaced as part of the capacity improvements initiative.

The record drawing functions as a critical planning and reference tool for bidders and project stakeholders to assess existing conditions and coordinate construction activities. By providing accurate documentation of the existing sanitary sewer infrastructure along Highway 30, the drawing enables contractors to develop accurate project estimates, identify potential conflicts or constraints, and plan construction sequencing and phasing. This documentation supports the project's objective to increase system capacity, improve reliability, and address existing conveyance deficiencies in key portions of the collection system within the designated basins.
