Surveying and Mapping for Roads Sample Clauses

Surveying and Mapping for Roads. All road features, culture, utilities, other surface features and certain sub-surface features must be located to allow proper design of the project and others that might affect project design. Amongst these are: • Existing right-of-way center lines and margins • Beginnings and endings of: curbs, gutters, flow lines, edges of traveled way, fences, gates, guard rails and other linear features, with intermediate shots as required • For all driveways: driveway centerline stations and widths. With curb and gutter, top and bottom of curb transition and the back of the ramp portion of the driveway. Without curb and gutter, elevations for top and flow line of any ditch and culvert and sufficient nearby elevations to allow for proper design of approaches. • Bridges: centerlines, corners, wingwalls, cross section of underpassing feature and other important points. • Other culture: signs, building corners, trees (with diameter at breast height (DBH=54”) noted if greater than 4”), parking lot corners, areas outside of the right of way and any other points pertinent to the project. • Utilities: manhole covers, access shaft diameter and offset to manhole, manhole diameter and material, all pipe locations, sizes, materials and inverts; water valve covers and tops of operating nuts; fire hydrants; pad-mounted boxes and transformers; power poles; painted locations of underground utilities; overhead lights and the lowest elevation of the lowest wires crossing street. • Drainage: drop inlet location, grate dimensions and all pipe sizes, materials and inverts; catch basin location, grate dimensions, local depression dimensions, surface dimensions and all pipe sizes, materials and inverts; manhole covers, access shaft diameter and offset to manhole, manhole diameter and material; culvert locations and dimensions and limits of any surrounding riprap; any other drainage features. • Cross sections shall be taken at all stations ending in +00 and +50, at either end of the project and one fifty feet beyond both project limits. Cross sections shall extend to at least the right of way margin. Be the margin on a slope, the top or toe of slope will be included. • At all BCs and ECs. • At all BCRs or ECRs of any cross street. • Grid of intersections with lines at fifteen-foot maximum spacing from MCR to MCR with a minimum of four lines in each direction. • Geotechnical boring sites. • Sketches showing the arrangement of things with occasional point numbers for orientation.
