2012/08/08 Council Agenda Packet

• 2 o Survey Control Points o Copies of City-furnished field books used Note: Provide other useful information, such as summaries of data and photos relating to existing structures (manholes, etc.) • Report apparent discrepancies or anomalies in information to the City for resolution. Additional work required to resolve incorrect information will be covered under Task 1100. This task will also require setting up an AutoCad Template and Description key file in order to efficiently process survey data in City of Everett Standards. Base Mapping. Provide base mapping utilizing current City Datum for detail design, including: • Locations of all public and private utilities, buried and overhead. o Coordinate with a private utility locate service for the underground utility services. The locate service will paint and mark the location of the utilities. Utility locates will be indentified as "center of structure" or"center of line". Field survey location of painted locations. o Provide measure-down and rim elevations for water line valves within the Mapping Boundary. o Compare to record research to reconcile gaps, overlaps or confusion. o Identify side sewer locations (and elevations, if available) using side sewer data from City records, supplemented with summary tables of side sewer stationing as provided by the Consultant from the CCTV inspections conducted previously for the Sewer"M" Project. O Topographic survey of right-of-way(ROW) corridors, including alleys, within the Mapping Boundary. Include all ground features, such as driveway cuts, trees, lane markings, walls, sidewalks, curbs, structures, utility poles, etc.). Attempt to obtain two point elevations at building corners of the nearest face of structures with which a pavement tie-in will need to be made from the alley. • Consolidate utilities and topographic ground survey with aerial mapping into one AutoCAD file. • Provide ROW and property lines per available records and found monumentation. Title reports will not be used as part of this task. • Show only existing easements that may be identified on City-supplied GIS-based mapping provided by the City. Easement research in not anticipated as part of this task. • Vertical and Horizontal control will be based on the adopted City of Everett Standards and map projection. Show TBMs for horizontal and vertical control from field survey work described above. • The existing city street monuments will be referenced for future relocations based on construction disturbance. Provide monument preservation in accordance with WAC Chapter 332-120 "Monument Removal or Destruction". Document monuments and benchmarks in Survey and Mapping Notebook. O Prepare Survey Control Plans for the project areas (four sheets are anticipated) containing project data, overall survey control data, project horizontal and vertical control, and construction stationing on centerline of alignment, both in tabular and graphic form. Control sheets shall incorporate City of Everett requirements for survey control on City projects. Survey Control Plans are to be prepared and sealed by the project surveyor. • Mapping will be performed at a one-foot contour interval. Spot elevations on hard surfaces will be shown on a separate layer. July 2012 r6.0 Page 7 of 19 Jacobs Engineering Group 17
