<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 reosipt of notice to proceed, a site visit
<br />j
<br />will be performed to markthe core/boring locations and evaluate access conditions for drilling equipment,
<br />Willdan will call USAfor underground utility locating at least 46 hours before any field work Is performed,
<br />However, all available subsurface utility Information should be provided/ Identified prlorto initiating field ex•
<br />ploratlon to reduce the potential for damaging existing utilities, Traffic control will be provided during drilling
<br />Borings/cares will be measured and visually logged in the field by an experienced representative. The log will
<br />include pavement sections thlokresses and subgrade conditions. The samples will be transported to Will -
<br />clan's gaotechnicai laboratory for testing,
<br />Laboratory testing of collected representative subgrade soils will determine their index and engineering prop.

<br />Subtask 4,04 — Preliminary Design Report Willdan will compile a Preliminary Design Report (PDR) for
<br />review and approval by the City. The report will contain a summary of 9 Subtask 4.04 Dellverablas
<br />the initial reconnaissance notes, utility provided information, field survey Preliminary Design Report
<br />I findings, any photographs of conditions for discussion, and the base de-
<br />sign concept with preliminary construction cost estimate. The report will be disoussed with City representa-
<br />tives to make reliable, cost effective decisions about the proposed street Improvements, water and sower re-
<br />habllitation/replacement methods.
<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 ramps, driveways, sewer and water repairs, in addition, the report will address the disposition of
<br />existing utilities and coordination, and anticipated requirements,
