<br />Meld exploration Including coring, drilling, and sampling at three locations to the maximum drilled depth of 10
<br />feet below ground surface within the limits of the project site. Upon receipt of notice to proceed, a site visit
<br />will be performed to mark the coralboring locations and evaluate access conditions for drilling equipment.
<br />W111dan will call USA for underground utility locating at least 4B hours before any field work Is performed.
<br />However, all available subsurface utility Information should be provided/ Identified prior to Initiating field ex-
<br />ploration to reduce the potential for damaging existing utilities, Traffic control will be provided during drilling.
<br />Borings/ooree will be measured and visually logged In the field by an experienced representative. The log will
<br />Include pavement sections thicknesses and subgrade conditions. The samples will be transported to Wilk
<br />dana geatechnicall laboratory for testing,
<br />Laboratory testing of collected representative subgradle soils will determine their Index and engineering prop-
<br />erfies.
<br />Option A: Geolechnicall Investigation will be used to Identify the soil properties for the trenching and backfill of
<br />proposed utilities.
<br />Option B: Providing recommendations for alternative new pavement sections.
