The Consultant shall perform all services required to make a complete topographic survey, in English units of measure, as required for the proper design and layout of the Project. DOTD’s requirements which shall govern this survey are specified in the current edition of DOTD’s Location and Survey Manual. Although currently acceptable surveying standards and methods, as approved by the Location and Survey Administrator, may be used. The Consultant shall request, in writing, from the Project Manager a copy of this manual for the Consultant’s information and guidance as to normal DOTD procedures in the conduct of topographical surveys. Deviations from the normal procedures must be authorized in writing by the Project Manager. The survey shall include, but is not limited to, one or more of the following: 1. Station the project centerline every 100'. Paint stations on paved shoulder, or where no paved shoulder exists, paint stations on travel lanes outside of apparent wheel paths. 2. Station reference points along the project in the event the painted centerline stations fade. 3. Station, offset and inspect all drainage structures. Note condition, cover, size, type, thickness, safety end treatment, headwall, length and other information required in EDSM I.1.1.11. Crosssection the roadway and ditches at cross drain locations. 4. Cross-section the roadway and ditches at a minimum of every 1000' but not less than 3 representative sections. Cross-section the roadway at the PC, PT, and apex of curves to determine superelevation rates, and at visible changes in cross slopes. Station and cross section intersecting roads or driveways within curves and note radii, if applicable. Cross section 0’, 25’, 50’, 100’, 200’ 300’ and 400’ from bridge ends or obstacles requiring guard rail protection. 5. Station and measure travel lanes and shoulder widths at transition points or changes in material type. Station and measure turn lanes, acceleration and deceleration lanes, crossovers, and parking lanes. Locate all roads and driveways within 200’ of bridge end.
