| 2207. | 31.14.8 | Modified proctor compaction test | per set of test | 20000 | 20000 | 20000 | 20000 |
| 2208. | 31.15.1 | Mobilization and demobilization of survey equipment and man-power: survey equipment comprising Total Station, RTK-GPS, level machine, Prism with stand, Tripod and others necessary tools & plants, triple for temporary camp and necessary work-force. | per site | 11390 | 11390 | 11257 | 11257 |
| 2209. | 31.15.2 | Detail digital topographic & physical feature survey of project area. The survey will cover the location and alignment of all topographic features inside the project area such as: Boundary, roads, exposed surface drains, walk ways, existing physical features such as trees, structures, exposed utility network etc. Spot land levels of the project area will be surveyed for contouring@ 5 m C/C. GPS should be used for establishing co-ordinate of global axis-Latitude/Longitude. Total station should be used for survey of spot level, detailed physical features etc. Field data shall be processed in GIS or Auto CAD Software. Finally layout map with all topographic and physical features shall be prepared using Auto CAD Software. All data & maps should be Submitted both in hard and soft format in 5(five) copy. | per Acre | 14955 | 18494 | 18360 | 18360 |
| 2210. | 31.2 | Sub - Soil investigation by 100 mm dia percussion wash boring including collecting disturbed and undisturbed soil samples in numbers as required for classification of soil, conducting SPT using auto trip hammer, stratification of layers, analysing physical parameters of soils like Atterberg limits, specific gravity, gain size distribution(by wet seive, hydrometer if required) , ground water table location, direct shear test, unconfined compression test, unit weight(dry/weight), natural moisture content ; C - ф values and other strength parameters to ascertain bearing capacity , skin friction, end bearings etc at every 1.5m intervel as per respective national/international standards and entering all these data & information in necessary tables & graphs and finally furnishing them in the form of standard sub-soil investigation report with CD containing video of sub-soil investigation operation of concerned site duly signed by competent engineer & exploratory office. | |||||
