11.1. On this issue, the lower authority had, interalia, observed that these damages are claimed by the applicant from the contractee due to the delays in making available possession of site, drawings & other schedules by the contractee beyond the milestones fixed for completion of project. These damages are consideration for tolerating an act or a situation arising out of the contractual obligation. As per the issues mentioned in the arbitration award, clauses 6.4 and 42.2 of the General Conditions of Contract (GCC) specifically state that in case of any delay in issuance of drawings or failure to give possession of site the engineer shall determine the extension of time and amount of cost that the contractor may suffer due to such delays in consultation with the employer and the contractor. Therefore the time of supply of the service of tolerance is the time when such determination takes place. However, the contractee/employer has not determined the cost of delay prior to arbitration award. It was determined only by arbitration award on 09.05.2019. There tore the time of supply of this service as per Section 13 of the CGST Act is 09.05.2019. The Consideration received for such forbearance is taxable under CGST and SGST @ 9% each under the chapter head 9997 at serial no. 35 of Notification No.11/2017-Central/State tax rate.
