Const of 30 mtr span foot bridge over Lohara Khad for Govt Senior Secondary School Lohara including approaches Tehsil Amb Distt Una H.P SH Preparation of Contour site plan Hydraulic Data and Geo Tech Investigation for safe bearing capacity

Preparation of Hydraulic data i.e. Topographical survey by Total station equipment for preparation of Contour site plan, cross-section at bridge site, 50m, 150 m & 300m upstream and down stream of the river, L-section of road and river, calculation of silt factor a including all carriage of material lead & lifts.

Geo-Tech Investigation for safe bearing capacity by conducting SPT/DCPT upto depth 15m as per IS:1892 by core drilling, at 2 No. Bore hole locations ( Quantity = 2x15 = 30m) for Lohara 30.00 mtr. Span foot bridge. 2.1 Mobilization of necessary equipments, men and materials for geotechnical investigation from one test location to another and remobilizing the same including provision of casing pipe. 2.2 Collecting undisturbed soil samples at including waxing, labeling, handling and transportation etc. 2.3 Determination of Standard Penetration Test (SPT) in all the bore holes at regular intervals and collection of the disturbed soil samples from SPT spoon. 2.4 Determination of natural ground water table and collection of water samples from each bore holes. 2.5 To conduct tests on different samples in the laboratory as such as Grain size Analysis, Atterberg limits, Density, Consolidation test, Shear properties, natural moisture content, and determine the engineering characteristics of the soil. 2.6 Presentation of data as per IRC:78 and work out the Bearing Capacity of the soil for design of the foundations for the construction of Proposed Bridges. 2.7 Silt factor
