Pre-construction site information is collected by performing a topographic <br /> j or planimetric survey of the site to determine the horizontal and vertical <br /> location of physical features. The result is used to create project plans, <br /> which is also performed by the Engineering Technician. <br /> ~ Pre-construction site information provided by the Engineering Technician <br /> to the contractor maybe in the form of the following: <br /> • Cut Sheets <br /> A listing of elevations and relative cuts or fills, and distance, to <br /> j structures to be built at markers placed in the field <br /> i Points lists <br /> A computer listing of plan points on the projecf site relative to <br /> ~ structures to be built <br /> j <br /> • Hubs and construction stakes <br /> Wooden markers placed in the ground with information relating to the <br /> <br /> j vertical and horizontal location of structures to be built <br /> • Benchmarks and control points <br /> Semi <br /> permanent to permanent markers and reference points with the <br /> elevation above Mean Sea Level and/or State Plane co-ordinates <br /> either in the format of 1927 North American Datum (NAD 27), 1983 <br /> NAD (NAD 83) or Metric co-ordinates <br /> d) Design research <br /> Research for design may include but is not limited to: <br /> • Review of video tapes and logs of wastewater and storm sewers for <br /> defects of the main line, services, manholes and catch basins <br /> • Review of private wastewater connection drawings to determine <br /> activity and location <br /> • Review of "as-constructed" drawings of wastewater, storm, roads, <br /> sidewalks, sub-divisions, individual buildings <br /> • Review sub-division plats, deeds and existing surveys <br /> <br /> ' Review of water, power, gas, telephone, cable TV and steam <br /> records <br /> • Review of aerial photographs <br /> The research method is typically accomplished by first creating a map of the <br /> proposed project site as a reference drawing. This is done using survey data <br /> collected in the field by the Engineering Technician and creating a drawing <br /> (using Auto Cad) which indicates the location of all existing utilities, structures <br /> and surfaces which are visible from the ground. <br /> The next step is to overlay the existing public right of way onto the drawing to <br /> indicate the limits of public improvements or the need to acquire additional <br /> right of way for the project. Right of Way information is stored on-line in the <br /> format of an AutoCad drawing indicating the entire city of Eugene. The <br /> Engineering Technician has to locate the area pertaining to the proposed <br /> project and extract that information from the Right of Way drawing and place <br /> it in the reference drawing in the correct location per state plane co-ordinates. <br /> The next step is to verify all information collected during the survey by <br /> comparing it to the "as-constructed" drawings within the city database.
