Specifications include, but are not limited to: Topographic Survey shall consist of 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. The DOTD’s requirements which shall govern this survey are specified in the current edition of the 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 not be limited to the staking of centerline when required and when physically possible and, where this is not possible, to the running of all ground traverses necessary to compute and establish centerline. Aerial photogrammetry may be used when feasible and by written agreement with the DOTD in developing the topographic surveys. This work shall include, for the control of the field survey and later use, the establishment of referenced iron rods along the Project, as may be necessary, to define the centerline and of a referenced system of bench marks on a closed level circuit. The survey shall also include the location and establishment of ownership of all utilities in the way of construction as specified in the manual. The Consultant’s attention is specifically directed to the requirement in the manual whereby a sketch of the survey line shall be submitted to the DOTD Location and Survey Administrator for approval immediately after the initial establishment of said line and prior to proceeding further with the survey. The Project survey control and horizontal alignment shall be based on the Louisiana State Plane Coordinate System, (NAD-83), as determined by G.P.S. observation. Subsurface Utility Engineering (SUE) – Consultant will provide accuracy and economy in project-driven utility inventories, through the application of technologies that are not otherwise readily available to DOTD, and to enable DOTD to assign various task such as project utility coordination, etc., on statewide projects using Subsurface Utility Engineering (SUE)
