Vertical load testing of piles in accordance with IS 2911 (Part IV) including installation of loading platform and preparation of pile head or construction of test cap as per standard procedure and dismantling of test cap after test etc. complete as per specification & the direction of Engineer-in-Charge.

Initial test for pile loads up to 600 MT (For each test)

Routine test for pile loads up to 350 MT (For each test)

Scope of Work i) The load tests shall be in accordance with the Indian Standard Code of Practice for Design and Construction of Pile Foundations IS 2911 (Part IV) Load Tests on Piles. For initial load test, test load will be 2.5 times the theoretical designed capacity of pile. For initial load test, arrangement shall also cater for additional 25% above test load and nothing extra will be paid on this account. Stresses in test arrangements (steel truss or plate girder) to cater for test load plus additional 25% load shall be within permissible limit as per IS:800 (as for permanent structure). For test frame, structural steel of grade conforming to IS:2062 shall be used. ii) Engineer-in-Charge will decide the locations and nos of initial load tests to be performed in different zones depending on variation in substrata. The contractor shall undertake construction of test piles required for initial pile load test in the initial stages of work using the same methodology and equipment which will be subsequently used for working piles. These tests shall be undertaken well in advance of working pile. No working pile would be allowed to be undertaken till satisfactory initial pile load tests have completed. Non-granting of permission for pile/pile cap by Engineer-in-Charge in such respect will not be considered as reason for delay or any claim thereof. The test arrangement to be employed shall be of nature which is quick to install and remove and easily transferable. Sufficient nos. of test arrangement will be required to be mobilized by contractor so as to conduct required nos. of initial load tests simultaneously. Vertical cyclic loading tests shall be carried out where specially needed and specified for separation of skin friction and point bearing components of the load carrying capacity of the piles. iii) Routine tests shall be performed on working piles to determine/check the load carrying capacity and settlement of the pile foundation. The sequence of piles for Routine Load Test shall be selected by the Engineer-in-Charge. The Routine load tests shall be in accordance with the Indian Standard Code of Practice for Design and Construction of Pile Foundations i.e. IS 2911 (Part IV) Load Tests on Piles. iv) The Contractor shall give the Engineer-in-Charge at least 48 hours notice of the commencement of construction of these piles which are to be subjected to Initial Tests. The load tests shall not normally be conducted unless the concrete is at least 28 days old.

v) All testing shall be done under the direction of experienced personnel conversant with the equipment and the testing procedure. Before the commencement of the tests, all the particulars regarding the test pile including boring data and concrete cube strengths shall be made available at site and shall form a part of the test report. vi) On completion of each load test the Contractor shall submit a report of the load test which shall include the following information: a. Description of soil conditions, ground water table, actual boring and installation records, concrete cube test results. b. Method of load application. c. Load settlement readings during loading and unloading. d. Time load-settlement curve. e. All other observation relevant to the test being conducted. Mode of payment:- Measurement shall be done in MT. Example:- For initial test load of 500 MT, amount payble for 1 test shall be 500 x 450 x (Contractor enhancement/rebate).
