Gantt chart offers a simple visualization of the project’s tasks associated with a building project. It is one of the simplest instruments used for building project scheduling . Each job or activity is represented by a bar that defines the start, end, and duration of the task. Gantt charts schedule and plan projects of all sizes. It shows the work planned on a specific day and other information.
The article explains the essential features of the Gantt chart, its advantages, and its disadvantages.
Gantt diagram or Gantt chart is a timeline bar chart developed by the American engineer Henry L.Gantt between 1903 and 1917. The method is simple, consisting of various project tasks represented with respect to the X and Y-axis.
Gantt chart is the most common scheduling approach used in the construction industry. Gantt chart is a popular approach that works for small and large construction projects. The approach conveys the information easily, even to the personnel who are unfamiliar with scheduling works.
A Gantt charts displays:
Gantt chart is used in building undertakings under the following circumstances:
The necessary steps involved in the development of the Gantt chart are:
1. Determine the activities from start to end of the undertaking. Identify the milestones that exist within the undertaking.
Find out the time required to complete each task or activity. 2. Analyze and set the order of each task from start to end.
3. Take a drawing paper and make a vertical & horizontal axis. Mention the tasks in the y-axis along with their milestone from top to bottom. The x-axis represents the time, and Y-axis is the area to mention individual tasks.
4. If there is any activity that must occur at a particular time, represent it using a diamond under the time at which the activity happens (Fig.1) Each task is represented by a rectangular bar that starts from start time and ends at the finish time of the job.
The Gantt chart shown above is a simple project schedule for seven main tasks. The duration of each task is marked in months. From the figure-2, the time duration of activity ” Layout and facilities” is one month. The activity “demolition” commences after the activity ‘A.’ Also, the activities B and C are performed and started simultaneously.
5. A blank rectangular bar represents the activities that start at a specific time and ends at the undertaking end.
Represent every task of the project in the Gantt chart without fail. With the completion of the task, fill the respective rectangle bar or diamond. 6.
The main advantages of Gantt Chart are:
Gantt chart is one of the simplest visualizations of undertaking tasks associated with building undertaking scheduling. Gantt diagram or Gantt chart is a timeline bar chart developed by the American engineer Henry L.Gantt between 1903 and 1917. Each job or activity is represented by a bar whose length represents the Start, end, and duration of the task.
To accurately monitor the tasks within the projects. Gantt chart is used in construction projects under the following circumstances: To communicate the complete plan and status of the project. To get an idea about the proposals for a simple project. To show the tasks that are dependent on the completion of the previous task. To instruct a process or sequence of working.
A Gantt chart represents the following elements: 1. The project start date 2. The complete tasks of the project 3. The person in charge of each task 4. The Start and finish of each task 5. The duration of each task 6. The tasks that come under a group 7. The tasks that overlap with each other 8. The finish date of the project The tasks that are linked 9.
Gantt chart is the most common scheduling method used in the construction industry. Gantt chart is a widespread method that works for small and large construction undertakings. The method conveys the information easily, even to personnel unfamiliar with scheduling works. It accurately communicates the undertaking progress and delay. It is an effective tool to keep track of the undertaking.
