Geotechnical Exploration Services Proposed Addition to Cass County Jail Fargo, North Dakota Scope of Services We propose the following scope of services in execution of the requested geotechnical exploration program for the above referenced project. We caution that our equipment can damage lawn areas and/or weak pavement sections due to considerable weight of the drill, While we will attempt to minimize such damage to your property, we assume the property Owner will be responsible for perfonnance and cost of repairs associated with damage to the grounds and pavements at this site by NT!. . NT! will contact the "One-Call" system for clearance of public utilities prior to start of drilling operations. We assume the Owner will notify NT! if private utilities are located on this parcel. We also assume the Owner is responsible for clearing, or will retain the services of a private locate company for clearing private utilities, if such are present on site. . We will mobilize a truck mounted drill to the project for advancement offour (4) soil borings to a depth of 25 feet and one (I) soil boring to a depth of 40 feet within the building footprint. Sampling will be perfonned at 2 Yz foot intervals to a depth of 15 feet with additional samples obtained at 5-foot intervals thereafter. . We plan to utilize "hollow stem auger" drilling techniques for advancement of the borings, and standard split spoon techniques or thin wall sampling tubes to collect soil samples. Soil sampling will be perfonned in general accordance with ASTM: D 1586, Field collected soil samples will be visually classified in accordance with ASTM: D 2488. Representative portions of samples will be returned to the laboratory for further examination, . We will measure for the presence of groundwater or lack thereof when we complete each soil boring. This infonnation will be recorded on the field notes for inclusion in final soil boring logs, We note that the detennination of the local groundwater surface may be difficult based on the limited time available for stabilization of the water surface within the boreholes. We assume each soil boring may be abandoned by placement of soils cutting within the borehole. . We will prepare a geotechnical exploration report for your use in support of the proposed construction. Our report will present our understanding of the proposed project, our findings and recommendations as defined below: . Our understanding of the project and anticipated loading for footings. . A general description of our soil boring procedures including a general description of the soils and groundwater conditions encountered at the project. We will also include logs of our soil boring, descriptions of nomenclature used for defining the site and drilling procedures, identify standards used in perfonnance of our field and laboratory testing, and a drawing defining the location of the borings relative to existing site features. . Specific comment and recommendations for quantifying the site for project construction will be presented. Such discussion will include net allowable soil bearing pressure and estimate of settlements for design of the structure footings, recommendations for construction including placement of fill, weather related impacts on construction during cold or wet periods. The scope of services is intended mainly for geotechnical purposes and will not include environmental recommendations. However you will be contacted if noticeable contamination is detected within soils recovered from the borings.
