3. What are temporary works?
Temporary works (TW) are the parts of a construction project that are needed to enable the permanent works to be built.  Usually the TW are removed after use.
EX- Scaffolding
Timbering in trenches
Shoring
Underpinning

4. Timbering in trenches Various Method of Timbering Stay bracing
Box sheeting
Vertical sheeting
Runners
Sheet piling

5. Stay Bracing Used method –Firm ground & depth of excavation
does not exceed 2 m.

6. Box Sheeting

7. Used method- loose soil & depth of excavation does not exceed 4 m.
A box like structure is formed by providing polling board, wales & struts.

8. Vertical Sheeting This method is adopted for deep trenches
(up to 10 m depth)
in soft ground.
The method is similar
to box sheeting except
that the excavation is
carried out in stages
and at the end of
each stage an offset
is provided.

9. Runners In case of soft ground runner system is provided.
The system is similar
to vertical sheeting.

10. Sheet piling
This method is used
Soil to be excavated is loose or soft.
Width of trench is large.
Depth of excavation is large.
Sub soil water is present.

11. What is Scaffolding?
Scaffolding, also called staging, is a temporary structure used to support people and material in the construction or repair of buildings and other structures.

12. Types of scaffolding
Single scaffolding
Double scaffolding
Needle scaffolding
Trestle scaffolding
Suspended scaffolding
Steel scaffolding
Patented scaffolding

13. Single scaffolding

14. This is the most common type of scaffolding and is widely use in the construction of brickwork..
It consist of a single row of standards placed at a distance of about 1.20m from the wall.
Standard are placed at 2 to 2.5 m interval.

15. Double Scaffolding

16. This scaffolding is stronger than the single scaffolding.
It is used in the construction of stonework.

17. Needle Scaffolding Used: Ground is week to support the standards.
Construction of upper part
of the wall is to be carried out.
It is required to keep the
ground near wall , free
for traffic etc.

18. Trestle Scaffolding In this type of scaffolding,
the working platform is
supported on movable
contrivances movable on
wheels.
Use: painting , repair work

19. What is Shoring? Types of Shoring
Shoring is the construction of a temporary structure to support temporarily an unsafe structure.
Types of Shoring
Raking Shores
Flying Shores
Dead Shores

20. Raking Shores

21. This is a system of giving temporary support to an unsafe wall.
The construction of raking shore, varies with the condition at site.
In this method In this method inclined members called rakers are used to give lateral support to the wall.

22. Flying shores

24. In this type of shoring horizontal supports are provided for supporting temporarily the parallel walls of the two adjacent buildings which may tend to collapse or damage.
If the walls are quite near to each other (up to 9m) single flying shore can be constructed.
When the distance between two parallel walls is more than 9m a double shore can be constructed.

25. Dead shores

26. Such type of shoring is provided for the following purposes:
Rebuild the defective lower part of the wall.
Rebuild the existing foundation.
To make large opening in the existing wall.
