Exhibit "A" <br />Small Services Contract <br />for provision of <br />Sewer Design Field Survey <br />for <br />Step II Design Froject #C-48-1248 <br />The term "sewer design field survey" as used above, refers to the <br />collection and compiling of physical data, to establish the accurate <br />location of pertinent topographic features as well as other physical <br />features which.are required to correlate sewer design with actual field <br />conditions. The information collected may include but is not limited <br />to the following. <br />1) Topography, surface conditions, details of paving to be <br />disturbed, underground structures or other unusual obstruc- <br />tions, and insofar as possible soil conditions. <br />2) Details of existing utilities with which a proposed sewer may <br />connect or interfere. <br />3) Locations of streets, alleys, streams or other surface features. <br />A. The proposer will nrovide the followina, services: <br />1) Al1 elevations will be on USGS datum. <br />2) Third order temporary construction benchmarks on 1,500 + foot <br />intervals along proposed sewer lines. <br />3) Install h" 0 X 18" iron markers (or suitable substitute) with <br />flaciged guard stakes at angle points, points of line intersec- <br />tions, center lines of streets, roads, highways, and fences. <br />Record angles of intersections with same. Such markers to be <br />referenced located to at least two visible reference points. <br />4) Develop field data in connection with railroad and highway <br />crossinas. <br />5) 6Vhere requested by City, the Proposer will perform a complete <br />topographic survey for 25' each side of the sewer base line at <br />50 foot intervals and any mid points where the surface may have <br />sudden changes due to creeks, ditches, streets, railroads, <br />highways, etc. All ground elevations to be the nearest 0.10 <br />foot. <br />6) Reference all sewer base lines where they cross existing.fences <br />by centerline station, distance to nearest cross fence or corner <br />marker and give angle of sewer base line with property line. <br />
