responsible for breach of contract and delay in, firstly, making available a clear and unhindered site and, secondly, on account of its decision on modification of pile foundation items, the Petitioner-union was not entitled to terminate the contract and get the contract work executed through another contractor at the risk or cost of the Respondent-contractor. After considering, accordingly, the cancellation of contract as unjustifiable and the amount of risk and cost worked out by the union as not recoverable from the Respondent-contractor, the learned arbitrator worked out the amount payable under the final bill by the Petitioner-union. Knocking off the risk and cost amount of Rs.29,89,967, the arbitrator worked out the amount payable to the Respondent in the sum of Rs.10,19,276. The arbitrator also held that there was no merit in charging penalty at double the market rate for the Schedule 'B' material not returned by the contractor. The arbitrator held that factors of wastage and off cuts were not considered whilst arriving at the consumed material. The arbitrator was of the view that single market rate recovery would suffice and, thus, considered the rate of Rs.160/- per bag and Rs.18/- per kg towards appropriate recovery and, accordingly, reworked the amount of recovery at Rs.1,86,339.40 instead of Rs.6,24,471.69 as considered in the final bill. Adding the difference of Rs.4,38,132.29 to the final bill amount, the arbitrator held that the total amount payable by the Petitioner to the Respondent was Rs.14,57,408.29.
