A Gantt chart is a type of bar chart used in project management to illustrate the timeline and progress of residential construction projects. It typically includes the start date, end date, and duration of each task within the project, along with any milestones or dependencies between tasks. Gantt charts are often used to provide an overview of how a project's timeline will impact all aspects of construction, including supplies, labor costs, subcontractors and other resources that require scheduling. They are also helpful for tracking progress and identifying any delays or problems that may arise during the course of construction. Gantt charts can be modified as needed throughout the project to reflect changes in schedule or budgeting needs.
