The Role of Tendering and Estimate Preparation in Executing Capital Expenditure Projects at Indian Oil Corporation Limited (IOCL)

Abstract

Capital expenditure execution in large public-sector energy enterprises depends not only on financial appraisal and budget sanction but also on the operational processes of cost estimation and procurement through which an approved outlay is converted into an executed project. This paper examines the role of tendering and estimate preparation in capital project execution at Indian Oil Corporation Limited (IOCL), with specific reference to practices observed at the Guwahati Refinery. Based on internship-based observation, the study documents the structured format used for estimate preparation, the application of a centrally maintained Schedule of Rates (SOR), and the use of budgetary offers where standard rates are unavailable. It further examines the three-tier tendering framework — Open, Limited and Single Tender — and the role of the Earnest Money Deposit (EMD) as a procedural safeguard. The paper argues that the key managerial challenge for an integrated energy company such as IOCL is not the availability of capital but the prioritisation and allocation of capital among competing investment requirements, and that structured estimation and tendering procedures are central to transparency, cost control and accountability in public-sector capital expenditure management.
