| 1 | Topographical survey of Airfield for Runway Extension work using Electronic Total station or DGPS equipments or other suitable equipment by taking reduced levels (OGLs) at 3mx3m grid with reference to Airfield Reference Point (ARP) of station and runway centre line as defined base line for survey work. Topographical survey shall clearly define the existing pavement, buildings, structures, well/static water tanks, different type of roads/paths, drains, culverts, electric lines, overhead land marks, major trees, manholes, boundary wall / fencing etc for newly acquired land at ICGAS Daman, Technical area (around 45.79 Acres of land, upto 50 Acres). The survey shall include marking of important structural lines, levels and contours along with natural and Man made features (Roads, Buildings, Drains and external services) within the land. On completion, Five sets of topographical survey drawing, five sets of Site plan along with soft copy shall be provided. Quantity survey of all items as required for extension of existing runway, in the land parcels as above, with referance to existing runway level. This shall include for carrying out calculations of Excavation / filling as per cross sections provided by department at the extended runway portion. The quantities involved for extension of proposed runway, resurfacing of runway, perimeter road, drain, electrical system, perimeter wall, watch towers, Turnpad etc including connecting with the existing infrastructure shall be worked out and submitted in 5 sets as per design parameters given by Departement. Design air field drains as per the topographical and met data considering Air field norms. Submission of five sets of detailed topograhical site plan, Level sheets, Contour plan at 0.50m intervals, proposed drain layout and sections. Detailed estimation for quantity of earthwork as per the profile (FRLs).Note: The quoted rate shall include for Mobilization and demobilization of tools / equipment’s and personnel required to execute the job. |
