If set in a cultivated field, the point shall be placed 12” below ground’s surface. Control shall be placed at the following locations and interval spacing:
Horizontal Control. Section Corner and quarter section corner locations must be referenced to the Johnson County Horizontal Control Network. As part of the design survey all Section Corners and Quarter Section Corners within the project area and others used for project control must be located, reference and state plane coordinates determined with GPS equipment. The coordinates and referenced ties shall be shown on the plans and the standard corner reference report submitted to the Kansas State Historical Society, the County Engineer, and cities project engineer within 30 days of the survey as required by state law. If a Johnson County Horizontal Control marker may be damaged by construction the County public works department should be notified prior to the bid letting. Any Johnson County Benchmarks, Johnson County Horizontal Control monuments and any Section Corner and Quarter Section Corners within the area surveyed for the project must be conspicuously indicated on the plans. All bench marks and section and quarter section corners and property pins within the construction limits shall include a note for the re-establishment of the monuments.
Horizontal Control. 3.1 Search and reconnaissance for record and geodetic control points. Recover and verify previous control points set by agent and/or client. Set and maintain intermediate horizontal control points.
3.2 Traverse/GPS through found monuments to establish primary control. Traverse/GPS through secondary control to densify control.
3.3 Office calculations, adjustment, tabulations of coordinates, and working drawings.
Horizontal Control. A system located in the field that provides a point of horizontal reference for all Work described in the Task Order.
Horizontal Control. A-E shall recover horizontal control monuments sufficient in density to enable A-E to search for, and to re-set, if required, monuments required to re-establish any boundary lines. A-E may be required to recover vertical control monuments (if required, this will be detailed in the CTO for a specific project). The type, character, and number of any monuments set shall be approved in advance and in writing by COUNTY SURVEYOR and all monument materials shall be furnished by A-E or as directed by COUNTY SURVEYOR. Copies of all unadjusted field notes shall be submitted to COUNTY SURVEYOR. All material submitted shall be approved in writing by COUNTY SURVEYOR. The basis of bearing and coordinate control shall be as detailed in a specific CTO. DocuSign Envelope ID: 416E67DA-07D8-4514-8A5E-E2D2BDF7D4D8 In the case of Prado Dam Basin Property Acquisition Contract Task Orders, the basis of bearing and coordinate control shall be the California Coordinate System of 1927 (NAD 27), Zone 6, and the vertical control shall be based on the Orange County Surveyor 1976 adjustment, as previously established and available in a manual entitled “Xxxxx Basin Horizontal and Vertical Control” available at the County Surveyor’s office. All found or set monuments shall be tied to the established control system as cited above.
Horizontal Control. After angular adjustment position closure ratio for closed traverse shall be a minimum of 1:20,000. Surveys shall achieve a spatial positional accuracy (95 percent Classification Confidence) of less than or equal to one tenth of a foot.
Horizontal Control. Consultant shall supplement the horizontal control points set as part of ODOT’s OR43: Arbor Drive – Hidden Road project according to Agency standards using terrestrial (Theodolite and Electronic Distance Meter (“EDM”)), Global Positioning System (“GPS”) (Static, Rapid Static or Real time Kinematics (“RTK”)) or a combination of both. Consultant shall set and adjust monuments in conformance with Agency guidelines. Guidelines are in the current “ODOT SURVEY POLICY AND PROCEDURE MANUAL” and “ODOT GNSS Guidelines”. Consultant shall use NAD83 (2011) Epoch 2010.00 for the horizontal datum and the Oregon Coordinate Reference System - Portland Zone for the coordinate system. Consultant shall establish supplemental vertical control points set as part of ODOT’s OR43: Arbor Drive – Hidden Road project based on the North American Vertical Datum (“NAVD”) of 1988. Consultant shall establish vertical control using GPS derived elevations or elevations established by differential leveling methods. Task 5.2 - Convert MicroStation File to AutoCAD/Civil 3D 2018 Consultant shall convert the MicroStation/InRoads files prepared as part of ODOT’s OR43: Arbor Drive – Hidden Road project prepared by OBEC in 2019 to AutoCAD/Civil 3D files using standards prescribed by the Client. Task 5.3 - Topographic Data and Basemap The purpose of this Task is to collect additional existing topographic features, outside the limits of ODOT’s OR43: Arbor Drive – Hidden Road project as described above to create a base map used to design this Project. Consultant shall collect topographic data, within the limits of the Project described in the SOW, of constructed and natural features using a variety of Agency approved methods. These methods include but are not limited to: collecting the data using terrestrial (Theodolite and EDM) and GPS (RTK), and must conform to all file naming and coding formats in accordance with Agency standards. Consultant shall collect the supplemental topographical data to create points and break lines in adequate quantity and in proper placement per ODOT’s Survey Policy and Procedure Manual, to accurately represent the surface of the ground to be included in the Surface Model. Consultant shall record all visible utility markings shown on power or telephone poles, vault tags, telephone pedestals (aka risers), cabinets, meters, fences or screened enclosures for gas regulators, and sanitary sewer pump stations and shall note these as well as ownership on the basemap.
