Preparatory works for expansion of Pantnagar Airport. SH-Topographical survey

Amount

Conducting Topographical Survey as well as cadastral survey with high precise Total station & DGPS/ETS instrument for preparing contour plan by taking spot levels at the spacing of every 10 meter or less in two mutual perpendicular directions keeping variation in levels within 0.5 meter including 10 (Ten) nos. temporary bench mark to be established on permanent structure by flying the level from the Permanent Bench mark (Aerodrome reference point), taking levels of bench mark, locating all existing main physical features (roads and road crossing, culvert, power line, electric poles, electric control panels, bench mark, trees, boundary line, buildings, storm water drains, internal roads, pathways, runways, taxiways, aprons, Parking bays, isolation bays, residential houses, highways, watch towers, fire stations, PAPI lights, Glide path, DVOR, ATC tower and other relevant structures/features with their +ve/‐ve elevation to be clearly marked on the body of drawing etc.) levelling with respect to permanent bench mark of survey of India or such other bench mark (ARP). Submission of: a) Five sets of colour printed digitized drawings (of Contour Plan, Topographical plan and Cadastral Survey Plan) printed by computer plotted and on reproducible medium like pen drive, after approval of draft print, grid plans showing contours on 0.5m interval on a scale of 1:1000 or suitable scale on suitably bigger sheet or bigger size sheet) both as decided by EIC. Contours should be generated with computer software, complete in all respect as per direction and satisfaction of EIC. b) Based on spot levels collected in respect of the said area, level sheet in excel format as well as signed copy in hard (in triplicate after getting it printed in suitable sized paper so that levels are readable) shall also be submitted for the entire area in a grid of 10 m x 10 m or lesser. Rate includes mobilization of equipments, manpower, movements of manpower, engineer at site, survey work which includes spot levels at 10 m interval, contour map with contour interval at 0.5m, cadastral work and submission of required drawings in soft and hard copy. Note: i) The survey work against this item shall be carried out in operational (in restricted working hours) as well as non - operational area. All men and vehicles shall be permitted to enter the operational area only on possession of security passes. ii) Longitudinal levels of centre line/camber line of existing runways, taxiways and aprons are also to be collected separately if the line does not fall in the grid created by consideration of 10 m interval or lesser. Same is also to be shown in all drawings as well as excel format as mentioned above. iii) Along with excel format, suitable soft copies of contours, topography incl. cadastral readable in relevant software (such as CAD and GPS data file) also to be submitted in pen drive as described above.
