Cost control

Cost control or management in property or project management is the process by which managers maintain costs under human resource management, assets, and capital expenditure to ensure that the project ends on a budget basis. Cost management depends on reasonable estimates and ongoing monitoring during the project. As a result, good cost control is essential for any construction business that wants to succeed.
