| 2192. | 31.13 | Conducting plate load test as per ASTM D1194 or equivalent standard providing required arrangement of three circular steel plates with minimum thickness of 25 mm and varying in diameter from 305 mm to 762 mm respectively or square steel bearing plates of equivalent area for minimum 50 tons loading capacity of hydraulic or mechanical jack assembly and applying load in 2 cycles with maintainging time interval of each loading increment of not less than 15 minutes. Continue each test until a peak load is reached or until the ratio of load increment to settlement increment reaches a minimum, steady magnitude. If sufficient load is available, continue the test until the total settlement reaches at least 10 percent of the plate diameter, unless a well defined failure load is observed and all other required materials, excavation, protection against collapse, preparation of test pit, calibration of hydrauic jacks with pressure guage (with an error not exceeding ± 2 % of the load increment used ) & dial gauges (an accuracy of at least 0.25 mm.) including plants and equipment, platform for loading & unloading, mobilization, demobilization, hire charge of load testing equipment (joist, jacks and other necessary devices), gunny bags, filling with sand & stiching gunny bags, execution of tests by engineer, data acquisition and preparation of test results in standard forms and other incidental charges as per standard practice and procedures including submission of plate load test report, furnishing all graphs and charts and with CD containing video of sub-soil investigation operation of concerned site, all complete and accepted by the Engineer-in-charge.
