City of Santa Ane
<br />a 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 />l will be performed to mark the pore/boring locations and evaluate access conditions for drilling equipment.
<br />Willdan will call USA for underground utility locating at least 4B hours before any flaid work is performed.
<br />However, all available subsurface utility Information should be provided/ Identified prior to Initiating field ex.
<br />pioration to reduce the potential for damaging existing utilities, Traffic control will be provided during drilling,
<br />■ Soringstoorse 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 Will-
<br />dan's gsotschnloal laboratory for testing.
<br />■ Laboratory testing of collected representative subgrade soils will determine their Index and engineering prop.
<br />erties,
<br />Option A: Osotsohnlcal Investigation will be used to identify the soll properties for the trenching and backfill of
<br />proposed utilities.
<br />■ Option B: Providing recommendations for alternative new pavement sections.
<br />• Option B: Performing a percolation test within a boring Subtask �k.03 Dalivsrablea
<br />drilled to a depth between 5 and 10 feet for BMP and green , Three hard copies ra draft actechnlcal

<br />■ Providing a draft report and presenting our findings, conclu. report and one sloolmnlo PDF' copy
<br />I sions, and recommendations for review by the City. After a Three hard copies of final geotechnioai
<br />receiving the City's comments, a final report Incorporating report and one electronic PDF copy
<br />the comments will be provided to the City, The report will be supported with a map Illustrating boring/core lo.
<br />cations and a summary of laboratory test results.
<br />Subtask 4,04 — Preliminary Design Report Willdan will complle a Preliminary Design Report (PDR) for
<br />review and approval by the City. The report will contain a summary of Subtask 4.04 Deliverables
<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 oonstruction cost estimate. The report will be discussed with City representa-
<br />tives to make reliable, cost effective decisions about the proposed street Improvements, water and sewer re-
<br />habilitation/replacement methods,
<br />During preparation of the PDR, Wliidan will review existing Information, such as the pavement management
<br />report, city sewer and wafter 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 utllitles and coordination, and anticipated requirements,

<br />Subtask 5.01 Construction Plans.
<br />f Willdan will prepare conceptual plans for City review, com- a Task 5.01 Deliverables
<br />ment and approval. Upon approval of the concept plans, ° Three hard copies of full-size conceptual plan
<br />the final design phase will be initiated. Willdan will submit layout and one electronic PDF format
<br />plans at the 80-, 50-, and 100-peroant levels of comple- " Three hard copies of full-slze and half-size plan
<br />tion. The City will provide review comments at all design submittals at 30-, 50-, and 100 -percent comple-
<br />stages. Willdan will address comments received from the tion milestones, one electronic PDF copy, and
<br />submittal reviews, Including comments received from one electronic Mlorostation copy In Val format,
<br />j other affected agencies and utilities. Wilidan will submit one, original, signed set of full-sized plans, a signed, un-
<br />bound, set of final specifications, and a copy of the final enginaer's opinion of construction cost to the City. One
<br />set of Mylars will be produced after 100% plans are approved by the City (upon request). Plans will conform to
<br />City standard plans and CARD standards and be prepared utilizing Midrostation VBI software,
<br />Option A: The plans be prepared In sufficlent detall to bid the rehabilitation of the Identified well — method to be
<br />determined by the City after review of the assessment report — and the proposed sewer and water facilities. UtII-
