A construction timeline refers to a visual representation of the schedule and sequence of tasks involved in a construction project. It outlines the critical milestones and deadlines, such as the start and completion date of each phase of the project, and serves as a guide for project managers, contractors, and other stakeholders involved in the construction process.

The construction timeline helps to ensure that resources are available when needed and that the project progresses smoothly and efficiently, helping to mitigate risk and reduce delays.
