Soil Investigation work and topography 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 5 meter or less in two mutual perpendicular directions keeping variation in levels within 0.5 meter including 3 (Three) nos.temporary bench mark has to be established on permanent structure by flying the level from the Permanent Bench mark(Airport reference point), taking levels of bench mark, locating all existing main physical features (road crossing ,culvert , allay, power line, bench mark, trees, boundary line, buildings, storm water drains, internal roads, pathways, Link taxiways and Parking bays etc, 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 five sets of colour printed digitized drawings printed by computer plotted and on reproducible medium like pen drive, after approval of draft print, with field books duly signed , grid plans showing contours on 0.5m interval on a scale of 1cm=10m on A1 size sheet orsuitable scale, preparation of drainage plan, rerouting of naturaldrainage/water bodies,if any on basis of site survey, Flood levels,hydrological survey and site data. To finalize the finished level of gradedground to match with DGCA/CAR/ICAO/AAI requirements for bothdirections and also to maintain drainage system considering flooding pattern of adjacent water bodies. as desired by EIC.Contours should be generated with computer software, complete in all respect as per direction and satisfaction of EIC. Rate includes mobilization of equipments, manpower, movements of manpower,engineer at site, survey work which includes spot levels at 5 m interval,contour map with contour interval at 0.5m, cadastral work, finalization of finished level/Profile as per CAR of ground area 500 acres consisting of Runway,RESA ,Perimeter road drainage system,physical features e.t.c and submission of required drawings in soft and hard copy.

Standard Penetration test on soil making bore holes(dia 100 mm) up to a depth of 3.5 m from existing natural ground level including collection of disturbed/undisturbed soil samples at 0.5m, 1.25m, 2.0m, 3.0 depth from existing Ground level or change in strata whichever is earlier etc complete as per particular specification & direction of Engineer incharge.

Plate load tests (PLT) to be conducted at proposed sub‐grade level for each pavement (i.e. for Runway, Basic strip, Perimeter rad etc.). PLT should be conducted as per 15:9214 with the following: i.
