       A network layout plan for the primary and secondary project control surveys shall be submitted to the
       Regional Land Surveyor for approval, prior to the beginning of any field work.

       All survey equipment shall be properly maintained and calibrated, and checked frequently. The National

       Department as requested.

2110   Primary Project Control Survey

2111   The (Consultant) (State) shall set permanent survey monuments (GPS Base stations, and Azimuth Pairs),
       along the project corridor.

       The project length is approximately _ km. _ GPS base stations shall be set within 7 km of the
       project site, to control secondary project control surveys, and photogrammetric ground control surveys.

         _ Azimuth Pairs shall be set at 3km intervals along the project corridor, outside the project
       construction limits, to control a Total Station Positioning System (TPS) Survey. The monuments in each
       pair shall be intervisible and spaced at more that 300m apart.

2112   The (Consultant) (State) shall use GPS Relative Positioning techniques to tie into NSRS HARN or
       CORS control stations and establish Primary Horizontal Project Control at the project site. The
       coordinate system shall be the New York State Plane Coordinate System (NYSPCS) NAD 83-96,
       ___________Zone, and the vertical datum shall be NAVD 88.

2113   The (Consultant) (State) shall use GPS, trigonometric or differential leveling techniques, to establish
       Primary Vertical Project Control at the project site. Level runs shall begin and end on different NSRS
       NAVD 88 bench marks of first or second order accuracy classification.

2120   Secondary Project Control Survey

2121   The (Consultant) (State) shall set __ __survey baseline stations and ___ survey benchmarks along the
       project corridor. The interval between adjacent traverse stations, and adjacent benchmarks, shall be
       about 300m.

2122   The (Consultant) (State) shall establish Secondary Horizontal Project Control at the project site, using
       GPS or TPS techniques. The survey baseline traverse shall start from one of the previously established
       azimuth pair and proceed one-way to close on another azimuth pair, to form a closed-connecting
       traverse.

2123   The (Consultant) (State) shall establish Secondary Vertical Project Control at the project site, using
       trigonometrical or differential leveling techniques. The vertical datum shall be the North American
       Vertical Datum of 1988 (NAVD 88). The secondary level run shall start on one NSRS benchmark and
       shall close on a different NSRS benchmark.
