## Question

Draw a Gantt chart of a project having at least 10 activities. Write its advantages.

## Short answer

A Gantt chart displays activities as bars on a time scale, comparing planned and actual progress. Advantages: simple to prepare and read, shows start/finish/duration of each activity, enables direct progress comparison, aids resource planning, and is easily understood by all stakeholders.

## Answer

#### Gantt chart

A **Gantt chart** is a bar chart in which each activity is drawn as a horizontal bar on a time scale; the bar is filled in as the work progresses, so that planned and actual progress can be compared. Example: house project of 10 activities (progress shown at the end of week 10; `#` = planned, `=` = work done, `|` = status date).

| Code | Activity | Duration (weeks) | Predecessor |
|---|---|---|---|
| A | Site clearing and layout | 1 | - |
| B | Excavation | 2 | A |
| C | Foundation (PCC and footing) | 3 | B |
| D | Plinth beam and DPC | 2 | C |
| E | Columns and brick walls | 5 | D |
| F | Roof slab | 3 | E |
| G | Plumbing and electrical conduits | 3 | E |
| H | Plastering | 3 | F, G |
| I | Flooring, doors and windows | 3 | H |
| J | Painting and finishing | 2 | I |

Reading at week 10: A, B, C and D are complete (on plan); E (walls) has done 2 of its 5 weeks (planned: it started at week 8, so it is on schedule); the rest have not started. Total duration is **24 weeks**.

#### Advantages
- Very simple to prepare, read and understand.
- Shows start, finish and duration of each activity and the total project time on one page.
- Planned and actual progress are compared directly, so delay is seen quickly.
- Good tool for communication with the client, management and site staff.
- Helps in planning of manpower, machine and material on a time scale.
- Cheap; no training or computer is needed.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. What distinguishes a Gantt chart?
   A. Bars are joined by arrows to show logic
   B. Only key events are plotted
   C. Bars are filled as work progresses so planned and actual progress are compared
   D. Durations are given as three estimates
   Answer: C. A Gantt chart records progress inside each bar against a time scale. (Key point: Gantt chart)

2. At the week-10 status in the example, which activities are complete?
   A. A, B, C and D
   B. A and B only
   C. A to E
   D. None of them
   Answer: A. A to D finish by week 8, before the status date; E has done 2 of 5 weeks. (Key point: Reading the status)

3. Walls (E) start at week 8 and have done 2 weeks by week 10. Relative to plan?
   A. Two weeks behind
   B. On schedule
   C. Two weeks ahead
   D. Complete
   Answer: B. E was planned to start at week 8, so 2 weeks of work at week 10 matches the plan. (Key point: Wall progress)

4. Which is an advantage of a Gantt chart?
   A. It shows the critical path and float exactly
   B. It gives probability of completion
   C. It handles very large networks well
   D. Simple, cheap and needs no training; delay is seen quickly
   Answer: D. Its strengths are simplicity, communication and direct plan-versus-actual comparison. (Key point: Advantages)
