Design Surveys are used by Architects and Engineers as the Base Map for their design of proposed buildings or site improvements. Design surveys typically consist of field surveys to locate and identify project specific horizontal and vertical control points, often times ties to existing survey markers to relate the design surveys to a project boundary, and a Topographic Survey to precisely locate and map street improvements, driveway cuts, existing asphalt grades, and utilities on and near a project site. Design surveys often include field surveyed cross sections of a roadway to locate and identify the positions and elevations of the ground on one side of the street and extending through the top back of sidewalk, back if curb, gutter flow line, lip of gutter, crown of road, and continuing across the street through the lip of gutter, gutter flow line, back of curb, top back of sidewalk, and ending at a point on the ground on the opposite side of the road. In addition, all visible utilities are located and more often than not, manhole lids and drainage inlet covers are temporarily removed so that we can physically measure the pipe inverts within those facilities. Design survey information is collected through our field survey operations using a hand held data collection device. Upon completion of our design surveys, field survey data is downloaded into our computers and a digital base map drawing is prepared. Base map drawings are then plotted on paper and field checked for accuracy. Any required revisions are incorporated into the base map drawings and a final drawing is plotted. The final drawings are then stamped and signed by a California Licensed Land Surveyor and provided to our client along with our digital drawing files.
