3. 1.What is the Time-Chainage Diagram?

4. 1.What is the Time-Chainage Diagram?
It is an extension of the Bar Chart (Gantt Chart).
enables the time dependencies between activities to be shown, together with their order and direction of progress along the job.

5. 2.What is the principal benefit?
The principal benefit is the management of work in confined spaces where typically only one operation can be performed at a time.

6. Description of Diagram

7. 3.History
Widely applied roadwork projects and in the development of the motorway system in UK for many years
used for the planning of the tunnelling and fixed equipment installation on the channel tunnel project
Discussed in proceedings of the Institution of Civil Engineers
Applicable only for limited types of project
not as widely appreciated in the industry as bar charts and network techniques.

8. 4. Advantage of Time-Chainage chart
When Constructing
Roads
Railways
Pipelines
Tunnels
Transmission Lines
Bridges

9. 4. Advantage of Time-Chainage chart
Easy to know
The order of activities or operations
Where activities are happening locationally
How activities must progress in relation to direction and distance
Time, key dates and holidays, etc.

10. 5.Example Business of constructing the road
The length of road = 3.5 Km
Starting point of construction = 0+000
Finishing point of construction = 3+500

11. 6 Activities Fencing Drainage Bulk Earthworks Footbridge
Retaining wall
Road Surfacing

12. 6 Steps

13. 6 Steps to draw diagram Step 1
Draw the diagram layout
Decide the intervals of chainage
1000m

14. 6 Steps to draw diagram Step 2
Select either the horizontal or vertical format
Draw an outline with time and distance (chainage)
Add main holiday periods allowing 2 weeks

15. 6 Steps to draw diagram Step 3
Make the main program activities or operations

18. 6 Steps to draw diagram Step 6
Complete all activities on the list

19. 6.Think about Advantage of Horizontal axis
-Easy to notice that has to be constructed.
Advantage of Vertical axis
-More easier to read by those familiar with bar charts.
The choice is a matter of personal preference.
