<br />3.2 Field Surveys and Mapping. Field surveys shall consist of updating Caltrans digital
<br />photogrammetric mapping, supplemented with field topography for determination of
<br />accurate elevations at conforms, and critical right-of-way or other controls. Specifically,
<br />the detailed survey information shall be prepared as follows:
<br />
<br />0 Perform GPS Survey in accordance with Caltrans' GPS Survey Policy, dated February
<br />1998 based on 1983 and 1988 datum.
<br />
<br />0 Set photo-crosses, paint and perform level runs and GPS Survey ties.
<br />
<br />0 Prepare and submit hardcopy survey of the proposed or existing control lines and
<br />monumentation.
<br />
<br />0 Prepare digital mapping in accordance with Caltrans requirements. Digital mapping
<br />shall be submitted in both AutoCad and MicroStation formats. Digital mapping
<br />submittal shall include aerotirangulation report, control point printouts, diapositives,
<br />aerial. panel and analytical point values, air photo index maps, and photo mylar of
<br />mapping.
<br />
<br />0 Perform field surveys necessary for design, specifically along the city streets, for
<br />conforms, and along Route 101 at the edge of pavement, roadway crown, temporary
<br />conforms for stage construction, locations of culverts, storm drainage facilities, utility
<br />covers, and inverts. Surveys shall consist of roadway cross-sections at 12 meter
<br />intervals, extending 5 meters beyond the anticipated right-of-way lines.
<br />
<br />0 Design for conforms shall be based on field surveyed cross-section data. Contour
<br />grading and roadway quantities shall be supplemented by calculation of the digital
<br />terrain model.
<br />
<br />0 Supplement topography with the location of existing fences, poles, signs, street lights,
<br />and trees. Trees shall be located by size and type, with drip line included.
<br />
<br />0 Field-locate visible utility facilities such as manholes, utility poles and bases, guy
<br />anchors, vaults, fire hydrants, and valve boxes.
<br />
<br />0 Survey points and lines shall be established, marked, identified, referenced, and
<br />documented as required, to complete the PS&E in accordance with the Caltrans Survey
<br />Manual.
<br />
<br />0 A copy of all original survey documents resulting from this contract, including original
<br />field data, adjustment calculations, final results, and appropriate intermediate
<br />documents shall be delivered to City/Caltrans.
<br />
<br />0 Prepare survey staking control plan.
<br />
<br />Survey notes and plots, closures and survey control plan
<br />Digital mapping submittals
<br />
<br />3.3 Compile Base Plans of Existing Facilities. Base mapping shall consist of digital plans of
<br />field-surveyed information, plus right-of-way, control, and property ownership information.
