2. Temporary Works What do we mean by Temporary Works?
Why is it important ?
What can go Wrong?
What do you need to know?

3. Definition of Temporary Works
An engineered solution used to :
support or protect an existing structure
or the permanent works during construction, or
to support an item of plant or equipment,
or the vertical sides or side-slopes of an excavation,
or to provide access.

4. Typical Forms of Temporary Works
Hoardings
Façade Retention
Piling
Working Platforms
Propping

5. Aluminium HD Shoring
Wall Forms
Groundworks
Column Forms

6. Refurbishment
Mast Climbing Platforms
Scaffolding
Edge Protection

7. Size
There is no official determination of what size of project needs a formal Temporary Works Procedure
Risk is the main factor
The policy requirements of BS5975
may, however, be applied to small jobs
in principle .

8. Why Is TW important? History is repeating itself with incidents
The supply chain is more fragmented into numerous sub-contractors
Fewer main contractors now have their own temporary works department
Proprietory systems are now widely used, and the design skills and product knowledge sits largely with the specialists.
Sometimes conflict between finance and safety
BS5975 now gives clear guidance
on procedures and responsibilities.

9. Common Problems With Temporary Works
No procedure, TWC or responsible person.
Lack of a competent contractor
No temporary works equipment available!
Inappropriate use of TW equipment
Incorrect estimation of loads to be supported.
Inadequate lateral bracing to resist lateral (wind) loads.
Lack of knowledge and experience of persons involved in temporary works design and erection/maintenance.
Unauthorised changes to an approved temporary works design.
Explain the issues and problems as detailed on the slides.
These tie into the last few slides as they mirror typical failings to the requirements of CDM 2007.

10. Still Going Wrong?
“Three cranes dismantled whilst foundations checked and strengthened”
“Demolition contractors damaged gas main causing major leak”
“Reversing Tipper Truck struck Groundworker”
“Workman trapped as building collapsed during demolition”
“Member of public injured after fall into excavation”
“Inadequate support for floor decking caused collapse”  
“HSE prosecute over fall risks discovered ”
“Ground worker escapes death in 4m deep excavation”
“Large fine follows failure to ensure contractor planning and control”
“Developer failed to inspect and maintain sign on major London project”

14. Temporary Works Co-Ordinator
“ The appointment of a temporary works co-ordinator ( TWC) should be the first operation in a chain of events culminating in the construction of a temporary works scheme”
“ The TWC should be the first point of contact between the designer and the site team, in all instances”
BS5975: 2008 Code of Practice for temporary work procedures and the permissable stress design of falsework.

15. Temporary Works Co-Ordinator
Competencies Required of a TWC:
Engineering knowledge and understanding
Management and leadership
Independent judgement
Health, safety and welfare
Interpersonal skills and communication
And
Experience appropriate to the complexity of the project
temporary works procedures and issues associated with the type of
temporary works
Source: Temporary Works Forum

16. Temporary Works Co-Ordinator
Role includes:
Co-ordinate all temporary works activities
Ensure :
a temporary works register is established
a design brief is prepared
a satisfactory temporary works design is carried out
changes are managed
checks are made
a permit to load and unload is issued

17. Supervisors Assist and liaise with the Temporary Works Co-ordinator
Supervise and check the temporary works
Supervise:
The erection/installation
Use
Maintenance
Dismantling
Liaise with TWC re any changes or modifications

18. What do you need to know?
Legal requirements: CDM, WAH, HASWA,LOLER etc.
BS5975 Code of Practice for Temporary Works Procedures
HSE SIM: The management of temporary works in the construction industry
Relevant Codes of Practice and industry guidance for : Hoardings, Formwork & Falsework, Scaffolding, Excavations, Working Platforms, Edge Protection etc.

19. What Should You Do?

20. “Plan, manage and monitor the construction phase in a way which ensures that, so far as is reasonably practicable, it is carried out without risks to health and safety”
CDM Regulations

21. Considerations Double- check your procedures? for: Design Briefs
Design changes during construction
The checking of the structure
TWC’s ability to spot scaffold hazards
Signing off the Permit to Load

22. Be in a position to respond to these questions……….
