the work on 08.12.1999. While dealing with point 2, on a consideration of the documentary evidence put in by both sides, it had been found that unprecedented rain, variance in soil, variation in the scope of work, variation in work order and other factors had caused delay. If IVRCL, by any act or omission on its part, was not responsible for the delay, which had occurred owing to causes beyond its control, it will be difficult to attribute to the contractor a failure to maintain the rate of progress of work. Further, the imposition of liquidated damages should be on a weekly basis for every week the work had remained unfinished.

Likewise, under Ex.C-7 also, difficulties experienced by IVRCL have been pointed out on account of the arising of situations for which it was not responsible and which had hampered the progress of work. The other correspondence that was exchanged and discussed while determining point No.2 would show that the delay had not occurred on account of any act or omission on the part of IVRCL in the course of the execution of the work.
