<br />• Field 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 cora/boring locations and evaluate access conditions for drilling equipment.
<br />Willdan 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 />dan°e geotechn€call laboratory for testing.
<br />' Laboratory testing of collected representative subgrade soils will determine their index and engineering prop-
<br />erties.
<br />■ Option A: Geotechnical 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.

<br />review and approval by the City. The report will contain a summary of Subtask 4,04 Detiverables
<br />the Initial reconnaissance notes, utility provided information, field survey Preliminary Design Report
<br />findings, any photographs of conditions for discussion, and the base de-

<br />During preparation of the PDR. Willdan will review existing Information, such as the pavement management
<br />report, city sewer and water documents and field review of the street to make recommendations regarding
<br />the construction needs, Including the location and extend of missing or damaged sidewalk, curbs and gutter,
<br />access ratnpsrdriveways, sewer and water repairs. In addition, the report will address the disposition of
<br />existing utilities and coordination, and anticipated requirements.
