00017948 Exhibit A Scope of Work and Technical Specifications~1.docx

This Scope of Work and Technical Specifications document outlines the requirements for the State of Oregon's coastal drilling and geotechnical investigation project (SPR881_Coastal_Drilling). The project involves conducting four coastal landslide geotechnical subsurface investigations that include drilling and sampling activities. The work encompasses comprehensive subsurface exploration to assess geological conditions at coastal sites affected by landslide risk. The scope requires the contractor to perform drilling operations, collect soil and rock samples, conduct laboratory testing, and provide detailed geotechnical reports documenting findings and recommendations related to slope stability and subsurface characteristics. Technical specifications detail drilling methodologies, sampling protocols, testing procedures, documentation requirements, and quality assurance standards that must be met throughout the investigation process.

The specifications establish requirements for drilling equipment, boring depths, sample collection methods, laboratory analysis standards, and reporting protocols to ensure consistent data quality across all four investigation sites. The contractor must comply with Oregon state regulations, safety standards, and environmental protection requirements applicable to coastal drilling operations. Work must be conducted in accordance with established geotechnical engineering practices and ASTM standards where applicable. The specifications include provisions for site access, coordination with state agencies, environmental compliance, and delivery of comprehensive technical reports with subsurface data, analysis, and geotechnical conclusions that will inform coastal hazard mitigation and land use planning decisions for the State of Oregon.
