Survey Work Scope

I just wrote this. It's a draft at this time. It would typically apply to surveys for right of way improvement projects. I invite your suggestions and (preferably mild) criticism.

Planning Phase

Planning phase will heavily rely on available GIS resources including tax lot mapping, LIDAR based contours, aerial photography, and surveys of record. This data may be augmented by field survey only when the record and experience in the area indicates significant irregularities.

Design Phase Survey

Design phase survey work calls for the performance of topographic Surveying Services within the defined work area, including but not limited to:

• Survey record, title, road, and as-built research including:
  • Relevant survey control data sheets and records;
  • Surveys and plats of record as available on the Washington County Ispirits database;
  • Current vesting deeds for affected properties;
  • Other deeds as may be referenced within the vesting deeds, the tax mapping, and survey and plat records;
  • Utility mapping and as-built documents from the Cityƒ??s GIS together with?ÿ utility company mapping records obtained pursuant to a ƒ??One-Callƒ? Utility Locate Request;
• Field Survey to establish appropriate spatial and elevation control to support the boundary, topographic to be performed, and to facilitate future right of way acquisition and construction phase survey work.
  • Monuments composed of ?«ƒ? diameter iron rod 24ƒ? long with plastic cap and/or Bernsten style 1ƒ? brass plugs, or better, shall be established at intervisible locations not more than 800ƒ?? apart within or adjacent to the defined project area. A minimum of three such monuments will be established for any project regardless of extent. Wood hubs, Mag Nails, and similar are not considered suitably permanent for this purpose.
  • The quality and composition of other survey control monuments that may be established as needed is at the discretion of the consultant.
• Field survey to recover and locate existing property corner monuments, of record or otherwise. Consultant shall proceed in observance of and in compliance with the provisions of ORS 672.047;
• Recovery of right-of-way lines and roadway, access, and public utility easements serving the project area.
• Determination of individual property lines to a degree of precision appropriate to the project needs.
• Requesting and coordinating public utility locates per the Oregon ƒ??One-callƒ? system.
• Topographic Field Survey including, but not limited to:
  • Planimetric features including
    • Curbs, gutter lines, sidewalks, edges of travelled ways and paved surfaces;
    • Fences and walls;
    • Buildings and other structures, including all those within 10ƒ?? of the defined survey area;
    • Signs, both public and private;
    • Traffic striping including lane markings, crosswalks,
  • Vegetation and landscaping including;
    • Limits of planted (landscaped) areas
    • Ornamental trees 6ƒ?? or greater in height, regardless of caliper
    • Native trees 6-inch diameter at breast height and greater
  • Topographic surfaces to a density and degree of precision sufficient to model?ÿ
    • paved and other hard surfaces to +/- 0.10ƒ??;
    • graded surfaces to +/- 0.2ƒ??;
    • natural ground surfaces to +/- 0.5ƒ??;
    • rugged/irregular surfaces to +/- 1.0ƒ??.
  • Evidence visible at surface of utilities, including
    • Sanitary and Storm Drain manholes tied at the point on the rim closest to the center of the manhole barrel;
    • Catch basins, ditch inlets, curb inlets and like structures;
    • Water vaults, valves, meters, fire hydrants, and like structures;
    • Natural Gas service vaults, valves, meters, and like structures;
    • Electrical and communication service vaults, ducting, junction boxes, risers, kiosks, meters and connections, etc.;
    • Traffic control poles, lights, vaults, junction boxes, risers, kiosks, loops, etc.;
    • Power and light poles, together with associated guy wires and poles;
    • Pavement cuts indicating the presence of underground utilities.
  • Utility location paint marks placed by others pursuant to a ƒ??One-Callƒ? utility locate request.
• Mapping of collected data shall be performed in a current version of AutoCAD Civil 3d and include:
  • All mapped features segregated in an orderly layering system,
  • Collected planimetric, utility, and vegetation features shown,
  • Sewer and drainage structures labelled with structure type and rim and invert elevations
  • DTM Surface model (Civil3d format) showing 1ƒ?? contours with 5ƒ?? index contours.
  • Resolved right of way limits and individual property lines, segregated by layers appropriately
  • Mapping shall include point data for all control and boundary monuments, segregated by appropriate layering and fully described as to the character of the monument.
  • Sheet files titled ƒ??Existing Conditionsƒ? appropriate for use in the design plan set shall be prepared in accordance with City of Beaverton CAD Standards.
