| 6 | Conducting various tests on soil samples and determination ofSoilProperties like Liquid Limit, Plastic Limit, Plasticity Index, Swell Index, Shrinkage Limit. |
| 7 | Conducting lab CBR (soaked and unsoaked) test of soil sample at proposed subgrade level. |
| 8 | Conducting Plate Load Test for modulus of Sub Grade reaction. |
| 9 | Conducting Permeability Test. |
| 10 | Conducting Tri axial Test. |
| 11 | Elastic modulus, Poisson’s ratio. |
| 12 | Conducting Consolidation Test, Vane Shear Test. |
| 13 | Determination of Specific Gravity. |
| 14 | Chemical Analysis of Soil (Total Soluble Sulphate, Chlorides, Organic Matter) and determination of Organic material in soil by wet combustion. |
| 15 | Chemical Analysis of Ground Water if encountered(pH, Total Soluble Sulphate, Chlorides). |
| 16 | Transportation of Equipments and soil sample collection charges, Visting charges, formulating borehole / test spots location plan, submission of detailed soil investigation report for Apron Extension Area and Boundary Wall (03 nos. sets in booklet form and 01 no. soft copy) making recommendations and suggestions complete as per particular specifications and directions of Engineer-in-Charge. |
| 17 | (i) Mobilization of necessary equipment and manpower for survey work, conducting topographical survey using GPS based survey equipment (Electronic total station / D.G.P.S etc.) with reference to permanent bench mark "ARP" (Airport Reference Point), of proposed site of Extension of Apron at Srinagar Airport as directed by Engineer-in-Charge and taking spot levels in 6mtr x 6mtr grid (Closer grids may be adopted in locations where abrupt/ sudden level differences are observed) and submission of contour maps with a contour interval of 0.50m. The survey data should include the location and all geographical details of various structures and other infrastructure like perimeter walls and roads, rock boulders, watch huts, watch towers, buildings, drains, drain outlets, electric poles, pathways, ditches, abrupt level differences in the form of depressions or mounts, trees with numbering, embankment including pitching, horizontal and vertical fences, and other relevant structures/features. (ii) Submission of 3 nos. (three) sets of Topographic plan and contour map in size not less than A0, with all spot levels in the scale of 1:1000 showing all topographic features,along with the original data (soft copy- CAD and GPS data file in compact disc). |
| 18 | Providing of tentative finished floor level (FFL) of Apron Extension Area in accordance with DGCA CAR / Annex-14 requirements and to match with finished levels of adjacent existing Apron, working out of tentative quantity of cutting and filling of earth required in Apron Extension Area to arrive at proposed finished floor level (FFL) as per specifications and directions of Engineer-in-Charge. |
| 19 | Transferring of Reduced Level (RL) of Airport Reference Point (ARP) situated inside IAF Area to a designated location near AAI Apron extension area as well as in AAI Residential Colony Area as directed by Engineer-in-Charge (EIC) by means of Total Station or suitable surveying equipment and establishing a permanent bench mark in accordance with CPWD specifications and directions of Engineer-in-Charge. |
