The City of Palo Alto has established a GPS Control Network and survey control monuments throughout the City to be used as the official survey control benchmarks. All surveying and engineering-related work shall use these monuments in order for the projects to be incorporated into the City's GIS mapping. To satisfy the City of Palo Alto horizontal coordinate & vertical datums, the surveyor must tie the requested work to the City GPS control monuments prepared by Bestor Engineers in 1994 and submit your northings and eastings in the City's coordinate system. The City will not accept deliverables in other coordinates systems and/or own local ("project") coordinate systems. The coordinates shown on the record of survey are based on the North American Datum of 1983 [NAD 83(1992 epoch)] in the California State Plane Coordinate System, (zone 3) in units of survey feet. Vertical elevations are based upon the NGVD 29 as per the USC&GS adjustment of 1967. Additional information concerning elevations and secondary vertical control benchmarks to be used for vertical control only is on file and available at the City of Palo Alto Public Works engineering surveying office. The data provided by Public Works is intended to be used as a reference. Horizontal and vertical control reference point data is available upon request. Copies of full size of the Record of Survey and Survey Control Monument maps prepared by Bestor Engineers, Inc. dated February 1994 are available at the Utilities Engineering Office. A California Licensed Land Surveyor is responsible to setup all control points needed to perform the survey work. The accuracy for all survey data shall be +/- 0.5 in; with an exception of gas meter risers on private properties to be +/- 0.5 ft. All survey data collected shall be certified by a California Licensed Land Surveyor. Roughly 30-40% of all gas meter risers are behind property fences, shrubs, or other obstructions. The survey data shall be measured in U.S. Survey Feet. Survey data shall be collected within the entire width of the street and on private properties to include all features identified below. The extents of the survey area shall cover the full intersections to curb returns. The consultant/contractor shall obtain approval from business/homeowners or occupants to access private properties or easements for collecting required survey data. No additional compensation will be made for delays due to private property access issues. The consultant/contractor shall provide necessary traffic control to meet the CPA Transportation Department's standards. No additional compensation will be made for traffic control on major streets. This Section ("License required") applies to this Request for Proposals. The consultant team for this work shall possess a valid Professional License in the following category: Licensed Land Surveyor
The City will verify the status of the consultant's license by checking the Consultant's State License Department of Consumer Affairs (Licensees - Department of Consumer Affairs (ca.gov). Question Deadline 01/11/2024 at 1:00 PM
