112. It is trite that the terms of the contract can be express or implied. The conduct of the parties would also be a relevant factor in the matter of construction of a contract. The construction of the contract agreement is within the jurisdiction of the arbitrators having regard to the wide nature, scope and ambit of the arbitration agreement and they cannot be said to have misdirected themselves in passing the award by taking into consideration the conduct of the parties. It is also trite that correspondences exchanged by the parties are required to be taken into consideration for the purpose of construction of a contract. Interpretation of a contract is a matter for the arbitrator to determine, even if it gives rise to determination of a question of law. (See Pure Helium India (P) Ltd. v. ONGC [(2003) 8 SCC 593] and D.D. Sharma v. Union of India [(2004) 5 SCC 325])
