• Aboveground utilities including valves, pull-boxes, meters, . and vaults. • Manhole Rims, and selected inverts. • All major surface features that define the shape of the terrain, such as tops and toes of slopes, grade breaks and natural ground Fences and walls Unless otherwise directed by the Client, the basis of horizontal control will be California Coordinate System of 1983 (CCS 83, Zone V, Epoch 2011,00). Coordinates will be expressed as grid values. in :terms: of the U.S. survey foot. Vertical control will be in terms of the North American Vertical Datum of 1988 (NAVD88), c, Miscellaneous Surveys, Pothole Locations, Manhole Dips: Consultant shall perform 16 hours of misc. field surveys as follows: Stakeout and collect as-built information for potholing surveys. • Detail pipeline dimensions, locations, flow directions, and inverts. Miscellaneous surveys to collect greater detail to supplement normal cross- section surveys. Prepare Base Maps a. Base maps will be prepared of the existing surface features obtained from the Design Survey task.A utility base map will be prepared for all existing utilities within the project limits based on the utility research and pothole task, The base maps will be prepared at 1:1 per City CAD standards. Deliverables: All CAD files 8. Geotechnlcal investigation a. A geotechnical investigation will be conducted for the construction of the sewer lines and water lines. The field exploration will consist of three (3) borings each to a depth of 15 feet below ground surface (or refusal) whichever Is reached first. The locations will be as close to the proposed pipeline Improvements as allowable, while avoiding existing utilities, The borings will be patched with Perms Patch if the existing surface is asphalt concrete, or quick set concrete if the existing surface is concrete. A professional traffic control crew will be provided during the field Investigation to Implement traffic control per WATCH. it is assumed the preparation of traffic control plans are not required, b. The purpose of the investigation will be to determine construction requirements for the pipeline Installations, The investigation will determine bedding and backfill requirements, groundwater table . depth, . geologic and seismic conditions, maximum stable side slopes for trench excavations, construction method requirements for new pipeline installations.. The findings and recommendations will be included In a report. c. Deliverables: I. Draft Report (pdf and hard copies -4) fl. Final Report (pdf and hard copies -4) 9. Alignment Selection Evaluate alignment alternatives considering construction cost, utilities, community impacts, permitting, access, connections to existing pipelines, and traffic control. Identify the proposed method of connecting to existing pipelines (ie. Hot tap, cu. in tee, other). Prepare "strip maps" showing proposed alignment, existing utilities, and existing street section. The strip maps will allow the City and RBF team to easily see the proposed alignments and to facilitate discussions if any alignment changes are needed. REP will conduct a workshop at the
