2 Contents What is the Time-Chainage Diagram?
What is the principal benefit? History Advantage of Time-Chainage chart Example Think about References

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 6 Activities on construction plan 6 Steps to draw Time-Chainage Diagram

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 OPERATION EXAMPLE Set up site Offices for contractor and engineer Activity 1 Fencing Activity 2 Drainage Activity 3 Bulk Earthworks Activity 4 Foot Bridge Activity 5 Retaining Wall Activity 6 Road Surfacing Holiday Christmas Shut down

16 6 Steps to draw diagram Step 4
Fill in the ‘site set-up’ and ‘clear site’ activities

17 6 Steps to draw diagram Step 5
Decide in turn where and when each activity will take place 15 Act1 12 16 Act2 Act4 -25 -16 Act5 -16 -24 15 20 Act3 25 30 35 Act6 Project Completion

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.
