NoDoC is a new platform that provides various cost estimation techniques for oil, gas, and petrochemical projects. It centralizes all necessary data for parametric, analogy-based, detailed, and resource-based cost estimation techniques. NoDoC allows users to select the appropriate cost estimation method based on the project phase and defines location and allowance factors for different regions and conditions. It produces cost estimates that can be viewed in different currencies and customized based on the user's role and the project scope, technology, and commercial conditions. NoDoC aims to make project cost estimation faster and more accessible.
