of Work 1. Preliminary Data Research & Review The RICK Team will research, obtain, and review available data as a reference to prepare the preliminary and final PS&E. Data includes: State, County, City, utility and other records/documents; existing street, signal, storm drain, gas, sewer and water main improvement plans; topographic data maps; record drawings; wet and dry utility plans (to determine size and location); survey centerline and private property monument data; and other pertinent information. Utility records request letters will be sent to the franchise and public utility agencies. These requests will be tracked via a table summarizing the request letters, the obtained data, both with dates sent and received. A copy of this table will be provided to the City and utility agencies. We will review the acquired information with the City prior to beginning any surveys and preliminary design. • We recognize that some utility companies treat as -built requests and plan coordination with low priority and therefore it will be incumbent upon us to start the research and coordination process upon receiving a Notice to Proceed for the project from the City. Furthermore, as mentioned above we will keep a complete and accurate log of communication with the various utility companies and keep the City informed of our progress in this effort. • Careful consideration to the existing utilities and their potential impact on construction cost and schedule will be taken into account throughout the design process. • A complete and accurate plotting of the researched utilities will be performed in order to achieve a utility base file for the plan preparation phase of the contract. 2. Design Survey/Existing Conditions Documentation RICK will perform the topographic survey including features that will influence the project design. The survey shall be in conformance with the State Land Surveyors Act and be performed under the direct supervision of a CA Registered Land Surveyor. Rick Survey will use California State Plane Coordinate System, NAD83, Zone V, US Survey Feet. Said survey will field locate monumentation to identify existing right-of-way and property lines within the project area. Tasks will include the following: 1. Establish horizontal and vertical survey and construction control for the complete length of the project. 2. Perform topographic field survey through conventional survey methods, as required, along the east/ west roadway to include the existing median and north/south lanes within the project limits and will include, but not be limited to: • Roadway half -width cross section elevations taken in the traveled way at 25-ft intervals (minimum) and grade breaks. The sections will include back of sidewalk, top of curbs, gutter flowlines, lip of gutters and lane line striping. • Locate features within the adjacent property including driveways, tops and toes of slopes, limits of parking area, curbs, trees, monument signage and found private utility appurtenances. • Locate existing improvements within the street right-of- way (i.e. above ground utilities, manholes, valve covers, utility vaults and covers, signs, trees, utility poles, traffic signal poles, cross gutters, local depressions, catch basins, sidewalks, pedestrian ramps, etc). • Reduce data to a form showing centerline stationing, offset from centerline, and elevation. • Provide 0.5 ft contours.
