ODOT barge-based geotechnical drilling for eight Umpqua River Bridge test holes

Oregon DOT is seeking barge-based geotechnical drilling for a bridge-protection project at the Umpqua River crossing near Reedsport. - Government buyer: State of Oregon, Oregon Department of Transportation (ODOT), Region 4; the solicitation identifies ODOT Procurement Office. Oregon Department of State Lands (DSL) authorization applies to the river work. - Scope: Complete eight geotechnical test holes from a barge at the US 101 Umpqua River Bridge. Design depth is 40 feet below the mudline; final depths depend on site conditions, with drilling specifications allowing up to 50 feet in soil/rock. - Drilling and sampling: Use mud rotary and/or HW casing advancement, followed by HQ triple-tube wireline coring to required depths. Perform standard penetration tests (SPTs) at directed intervals and Shelby-tube sampling where suitable soils are encountered. Provide eight OWRD geotechnical hole reports and abandon the holes under applicable requirements. - Bid quantities: 14 tugboat/barge days; 280 feet of mud-rotary drilling; 40 feet of HQ triple-tube wireline core drilling; 20 feet of HW casing-advancer drilling; 96 SPTs; 8 Shelby-tube samples; 320 feet of drill-hole abandonment; 16 standby hours; plus one each for administration, rig mobilization, per diem, pollution-control BMPs, and drums/disposal. Quantities are estimates and may be adjusted to actual measured work. - Notable requirements: Barge access and stable positioning are required, with daily transport and emergency egress support. The contractor must contain drilling fluids and cuttings, prevent releases of fuel and other pollutants, and handle disposal. SPTs must follow ASTM D1586; Shelby-tube sampling must follow ASTM D1587. DSL authorization conditions and seasonal in-water work restrictions also apply. - OEMs and vendors: No commercial OEMs, manufacturers, or vendors are named. One attached bid-pricing summary identifies Oklahoma Department of Transportation, while the solicitation and technical documents identify Oregon DOT; this agency-label discrepancy should be verified. - Schedule and authorization: The project is a short-duration effort with no option years or annual subscription. The source documents give inconsistent work windows. Required DSL authorization must be in place before the applicable work, and post-project rectification reporting is required.
