The history of construction project management can be traced back to the early 20th century with the introduction of prefabrication, leading to the establishment of building codes, standards, and specifications. As the complexity of the building process increased due to environmental, energy conservation, sustainability, safety, and other issues, the need for project management emerged. Project management involves the application of knowledge, skills, and techniques to execute projects effectively and efficiently, aligning them with business goals to improve competitiveness.The Project Management Institute (PMI) defines project management as the integration of management principles, methodologies, and techniques with the art, science, and craft of building. The PMI's PMBOK Guide contains standards and guidelines for project management practices, including scope, time, cost, quality, communication, human resources, risk, procurement, and stakeholders.A key tool in project management is the Work Breakdown Structure (WBS), which sets a project's scope by breaking down its overall mission into specific, increasingly specific tasks. MasterFormat is a standardized format for specifications developed by the Construction Specification Institute (CSI) in 1948, providing a clear communication framework among designers and builders.Breaking down the project into smaller tasks allows for quantification and pricing, enabling accurate estimation of project requirements. This enables project managers to better plan, execute, and control their projects' progress.
