About this file
The document is an Oregon Department of Transportation (ODOT) Standard Drawing RD312 for Subsurface Drain Installation, dated 2024 with an effective period from June 1, 2025 to November 30, 2025. The technical drawing provides detailed specifications for Type 1 Subsurface Drain Installation, including comprehensive diagrams and instructions for drain pipe placement, outlet protection blocks, and associated infrastructure components. The drawing includes multiple views - elevation, plan, section A-A - and details pipe dimensions ranging from 3 to 8 inches in diameter, with specific guidelines for drain pipe installation, mesh for rodent control, and outlet protection requirements.
The standard drawing is part of a broader highway infrastructure project in Jackson County, specifically related to the ESB Paving and Subgrade Drainage contract. The project is exclusively reserved for certified Emerging Small Businesses (ESB) through the Certification Office for Business Inclusion and Diversity (COBID), with a requirement that the selected contractor must perform at least 51% of labor using their own workforce. The procurement follows Oregon Revised Statute 279C.355(1)(g), which allows exemption from standard competitive bidding for public improvement contracts under $250,000 when awarded to certified ESB firms. Liquidated damages are set at $100 per calendar day for delays beyond the substantial completion date of June 30, 2025, with proposals due by May 21, 2025.
