Specifications include, but are not limited to: The scope of this project is to provide geotechnical investigation services, including all equipment, labor, machinery, supplies, and materials to access and drill up to ten geotechnical borings for the I-84 (Westbound) over Union Pacific Railroad bridge replacement project in Hood River, Oregon. Several of the borings are located within a wetland and subject to in-water work restrictions. The remaining borings are located on slopes and require site preparation prior to drilling. Region 1 Geotechnical Engineering / Engineering Geology (R1 Geo) has prepared these specifications and anticipates hollow stem auger, mud rotary, and rock coring techniques. This work shall include, but not be limited to, obtaining right-ofentry and other permits, site preparation, mobilization/demobilization to/from the site and within the project area, drilling operations, sampling, supply, and containment of water for drilling operations, containment and disposal of drill cuttings and fluids, and site clean-up and restoration.
