Performing Lateral load test on two piles or two groups of piles by introducing a hydraulic jack with gauge between two piles or pile groups under test by applying horizontal loads in increments of about 20% of the estimated safe load at each stage and applying the next increment after the rate of displacement is nearer to 0.1 mm. per 30 minutes till the total displacement becomes, 12 mm at the cutoff level including the cost of arranging the entire set-up, hire charges of all implements including at least two dial gauges, preparing the pile head if necessary, and removal of all arrangement after completion etc. complete in all respect including cost of carriage of all materials and as per IS specification and direction of Engineer-in-charge.

Performing Vertical load test on single Pile in accordance with IS:2911(Part-IV) by hydraulic jacks on pile/piles with 1.5 times the design load including preparation of the head of piles with concrete of required strength for receiving the jacks with all ancillary arrangements for setting up gauges, construction of suitable platforms, keeping the loads and dismantling and removing all arrangement etc. complete as per IS specification and direction of Engineer-in-charge) Testing load between 200 T and 250 T.

Integrity testing of Pile using Low Strain / Sonic Integrity Test / Sonic Echo Test method in accordance with IS 14893 including surface preparation of pile top by removing soil, mud, dust & chipping lean concrete lumps etc. and use of computerized equipment and high skill trained personal for conducting the test & submission of results, all complete as per direction of Engineer-in-charge) Within 50 km. radius from Raj-Bhavan
