This document comprises a "FINAL Geotechnical Report" for the Red Grade Road project (WY FLAP SHE 26(1)) in Sheridan County, Wyoming. It details the Federal Highway Administration's (FHWA) geotechnical engineering study, including geological and seismicity assessments, subsurface investigations, and recommendations for rehabilitation and minor realignment. The report covers cut and fill slopes, rockfall mitigation, special rock embankments, rock buttresses, and rockeries. It also includes detailed soil and rock descriptions, laboratory test results (gradation, Atterberg limits, soil classification, corrosivity), boring logs, and photographic documentation. Appendices contain laboratory test results, photographs, and excavation characteristics of rock.

• Ripper Production Graphs: Estimated production rates for Caterpillar ripper models (D10T2, D11T, D11T CD) based on seismic velocity.
• Rockery Stability Analyses (Appendices E & F): Global and external stability analyses for rockeries at various station points along Red Grade Road. These include detailed calculations for material parameters, wall geometry, loading conditions (including traffic live load), and factors of safety for sliding, overturning, bearing capacity, and internal stability under static and seismic conditions.

This report provides critical geotechnical information essential for bidders. It outlines existing site conditions, geological hazards, and offers detailed recommendations for construction elements like slope stability, embankment construction, and retaining structures (rock buttresses, rockeries). The subsurface data, including soil and rock properties and excavation challenges, is crucial for accurate cost estimation, equipment selection, and risk assessment. The stability analyses and ripper production graphs directly inform the design, construction methods, and expected performance for earthwork and rockery features, ensuring compliance with safety and performance standards and impacting project planning and execution.

This memorandum presents a summary of the hydrologic and hydraulic analysis conducted for the Red Grade Road project, located in Sheridan County, Wyoming. The analysis covers approximately 2.5 miles of the road and focuses on proposed widening, resurfacing, and drainage improvements. It details the evaluation of 18 cross culverts, 5 parallel culverts, and one pedestrian bridge, along with an irrigation ditch crossing.

This document is crucial for potential bidders as it outlines the existing conditions, the methodology used for analysis (Rational Method and HY-8 inlet control analysis), and specific recommendations for culvert replacements and drainage improvements. Key details include:

• Hydraulic Design Criteria: Adherence to Federal Lands Highway Project Development and Design Manual standards, including 25-year event design for cross culverts and 10-year for parallel culverts.
• Analysis Methods: Use of the Rational Method for flow rates and HY-8 for inlet control analysis, considering site-specific conditions like steep slopes.
• Specific Recommendations: Detailed recommendations for upsizing or replacing individual culverts (e.g., C04 to be upsized to 48", C08 to be shifted), installing flared end sections, and using riprap for ditch lining.
• Scope of Work Clarification: Explicitly states that work within parking lots (culverts P01-P05) is outside the scope, and the pedestrian bridge (B01) is assumed to be left in place.
• Ditch Improvements: Recommendations for ditch grading and lining with Class 1 riprap to manage storm flows and improve stability.

This information helps bidders understand the technical requirements, scope of work related to drainage infrastructure, and potential challenges or specific construction needs for the opportunity.
