Written by GovTribe AI · Apr 7, 2026

This is a technical drawing attachment (Attachment C) for the Oregon Department of Fish and Wildlife (ODFW) Clackamas Hatchery Siphon Modifications project. The document comprises a comprehensive set of 21 engineering drawings and specifications prepared by a professional engineer (Logan C. Allender, License #82303, expiring 12/31/25) to guide the renovation work at the hatchery facility. The drawing set includes location and vicinity maps, site plans, demolition plans, civil engineering plans, structural plans and details, mechanical building layouts, siphon hydraulic profiles, process flow diagrams, and vacuum system schematics. The drawings are indexed with standard abbreviations and specifications, covering existing conditions, proposed modifications to siphon piping, demolition of existing structures, and construction of a new siphon building. The document was finalized on April 28, 2025, and reflects the technical scope required for contractors bidding on the invitation to bid (ITB) for siphon modifications work.

The drawings serve as the primary technical reference for contractors to understand the full scope of work including demolition, new piping installation, and new building construction at the Clackamas Hatchery facility. The document does not contain pricing information, contract terms, set-asides, bidding timelines, or award details, as it functions solely as the technical design and specification attachment referenced in the related ITB. Contractors responding to the ITB would use these drawings in conjunction with other contract documents to develop their bids and project execution plans.
