Judgment :- 1. The petitioner in O.P.No.949 of 2010 is referred as the petitioner in this order and the 1st respondent in O.P.No.949 of 2010 is referred as respondent in this order. 2. The respondent obtained a contract from Railways for gauge conversion and the petitioner was given sub contract under work order dated 28.2.2007 for construction of six minor bridges bearing Nos.616 to 621 upto pile cap level and the contract was on unit rate basis with items, quantities, rates prescribed to the annexure to work order. Initially, the contract price was fixed at Rs.15,12,450/-. It was also agreed that the respondent's site Engineer and the Project Management Consultant (P.M.C.) of the Rail Vikas Nigam Ltd., (RVNL) would make a joint measurement of work along with the petitioner and the payment would be made as per the joint measurement certified by those two persons. The petitioner started dismantling and commenced earth work in Item No.1 of work order in respect of bridge No.616 and raised bills. There was a misunderstanding between P.M.C and the petitioner and according to the petitioner, P.M.C. refused for joint measurement and therefore the petitioner alleged that he was forced to negotiate with the General Manager of the respondent to reduce price in respect of Item No.1 from Rs.180/M3 to Rs.95/M3. Thereafter, on 16.5.2007 the respondent issued an amendment to the work order whereby the size of the bridges were increased in several times and the contract price was also increased to Rs.32,69,750/-. It is alleged by the petitioner that by reason of the revised plan and size of the bridges as per the first amendment dated 16.5.2007, the petitioner was made to redo the work of the same bridge two or three times as there was change in the length of the barrel and therefore the petitioner sustained loss of Rs.3.00 lakhs. Further, due to water stagnation the petitioner was not able to carry out the work of other bridges and the petitioner was also not able to complete the work due to the want of proper supply of good quantity and dimension of steel and the steel supplied by the respondent was also taken away by the respondent at the later point of time. When those defects were pointed out, the contract period was extended by 10 more months and amendment No.3 dated 6.3.2008 was served on the petitioner in the month of July 2008 whereby the rate was increased but the scope of the work was reduced. Nevertheless, the petitioner already commenced and carried out the work as per the work order dated 28.2.2007 and the petitioner sustained heavy loss in carrying out the work. The respondent directed the petitioner to form ramp connecting the excluded bridges and directed the petitioner to execute the work in Bridge No.617 and also contradictory to the terms of the work order dated 28.2.2007 the respondent unilaterally handed over the works that were assigned to the petitioner, to the third parties without notice and without terminating the contract. Therefore, the petitioner by letters dated 20.8.2008 and 1.9.2009 demanded payment for the work done and also issued lawyer's notice followed by two letters dated 4.10.2008 and 16.10.2008 and also requested to refer the matter to arbitration. As there was no response from the respondent, the petitioner filed O.P.No.281 of 2009 on the file of this Court for appointment of arbitrator and the Hon'ble Justice K.Raviraja Pandian was appointed as arbitrator and before the arbitrator the petitioner made a claim for Rs.17,40,000/-and later enhanced the amount to Rs.20,90,350/-. 3. The respondent admitted the work order dated 28.2.2007 and the amendments to the work order dated 16.5.2007 and 6.3.2008, but denied the allegation that due to the non-supply of materials and due to the conduct of the respondent, the petitioner could not complete the contract and submitted that at the request of the petitioner the time limit was extended and as the petitioner failed to complete the work, there was no other alternative for the respondent to entrust the work to the third parties and therefore the respondent issued letter dated 12.1.2009 terminating the work order and by reason of the failure of the petitioner, the respondent also sustained loss and the petitioner is not entitled to any amount as claimed by him. 4.
