Proposal for Geotechnical Engineering Services Orange County Board of Elections Expansion | Hillsborough, North Carolina Spetmeber 19, 2025 | Terracon Proposal No. P75255087 Facilities | Environmental | Geotechnical | Materials Exploration efforts require advancing soundings/borings into the subsurface, therefore Terracon will comply w ith local regulations to request a utility location service through NC One-Call. We will consult with the Owner/Client regarding potential utilities, or other unmarked underground hazards . Based on the results of this consultation, we will consider the need for alternative subsurface exploration methods, as the safety of our field crew is a priority. We will contract the services of a private utility locator prior to mobilizing to the site. Terracon will not be responsible for damaging private utilities not disclosed to us. Terracon is providing this service to assist the Owner/Client. Fees associated with the additional services are included in our current Scope of Services. Detecting underground utilities depends on the composition and construction of the utility line; some utilities are comprised of non -electrically conductive materials and may not be readily detected. The use of a private utility locate service does not relieve the Owner of their responsibilities in identifying private underground utilities. Utility locators should be given access to utility vaults to locate private utilities. Please contact us if additional planning and coordinating should be done before the utility locating is completed. Site Access and Safety: Terracon must be granted access to the site by the Property Owner. By accepting this proposal, without information to the contrary, we consider this as authorization to access the property for conducting field exploration in accordance with the Scope of S ervices. We plan to access to the work area during non -holiday, normal business hours (Monday through Friday between 7:00am and 5:00pm). Please contact us so we can adjust our schedule and fee if the project requires performing our work during night hours, weekends or holidays. Laboratory Testing The project engineer will review field data and assign laboratory tests to understand the engineering properties of various soil strata. Exact types and number of tests cannot be defined until completion of fieldwork, but we anticipate the following labora tory testing may be performed: ■ Water content ■ Grain size analysis (percent fines only) ■ Atterberg limits Our laboratory testing program often includes examination of soil samples by an engineer. Based on the results of our field and laboratory programs, we will describe and classify soil samples in accordance with the Unified Soil Classification System (USCS).
