Control Base is the established baseline (e.g., Scope, Cost, Schedule, and Performance) against which project performance is measured and controlled that serves as a reference point for comparing actual progress, costs, and schedule against the planned targets. The Control Base is developed as a taken-off from construction drawings that is a quantified basis represented a true picture of service or materials to be installed. Once the Control Base is established, project controls are used to monitor and measure actual project performance against the baseline.
