1. Temporary Works – P8
Project Practice

2. Temporary works are an essential part of construction process
Construction would not be possible without some form of temporary works.

3. Definition
“any temporary construction necessary to assist the execution of the permanent works and which will be moved from the site on completion”
J. R. Illingworth

4. The Site and it’s Boundaries
Provision of temporary access roads, bridges, temporary support to adjacent buildings – shoring and waterproofing.
Protective measures when plant is required to travel under HT lines or are working adjacent to HT lines.

5. Safety measures when working adjacent to railways
Protection of the public adjacent to the works or where rights of way are to be maintained.
Safety measures when working adjacent to railways
Hoardings and fencing plus traffic management.

7. The Site Set – UP
Provision of site offices, toilets, storage facilities, first aid room, canteens and drying facilities and appropriate services.
Where overseas work is concerned, camps and other facilities may also be needed.

9. Temporary Works Associated with Plant
Provision of crane tracks and bases.
Provision of hoist foundations.
Temporary anchorages to structure of cranes and hoists.

10. Foundation and services for mixing plants
Power supply for cranes hoists, bar benders

11. Safe Places of Work and Access
Scaffold required by law and to the standards laid down by the regulation.
In providing scaffolding, public safety must be considered – netting to stop falling materials, safe access under scaffold which have to be erected over a pavement.

12. Work in Excavations
Legislation used to require that all excavations more than 1.2m deep must be adequately supported. This is now dependant on ground conditions irrespective of the depth of excavations.

13. In addition, rescue equipment and testing facilities are necessary where there is a risk of a foul atmosphere in the excavation

16. In Situ Concrete Work
Provision of formwork or false work adequate to resist the concrete pressures arising and the loads imposed to be supported until the concrete cure to a sufficient strength to support itself.

17. Erection of Structural Frame
Establishing special lifting gear, methods of work to achieve safe access and temporary support to provide stability to structural members while in the process of erection.

18. TW Schedule for a Major Building.
Construction mainly involves two fundamental activities:
Handling of materials and –
Their fixing in the final location

19. Construction Method
Handling is a combination of both plant and labour.
Whilst fixing is a handling operation
For construction to take place TW must be used as it enables both plant and labour to work efficiently and safely hence:-

20. Material Handling (Plant and Labour) + TW = Construction Method
