Frequently asked questions Temporary works Permanent works are the parts of a construction project that will be used and remain in position for a long time eg 6. This includes buildings and structures such as bridges, roads, retaining walls, etc. The construction of most types of permanent works will require the use of some form of 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 eg access scaffolds, props, shoring, excavation support, falsework and formwork, etc. Sometimes the TW is incorporated into the permanent works eg haul road foundations and crane or piling platforms may be used for hardstanding or road foundations. It is very important that the same degree of care and attention is given to the design and construction of temporary works TW as to the design and construction of the permanent works. As TW may be in place for only a short while there is a tendency to assume they are less important. This is incorrect. Lack of care with design, selection, assembly, etc leaves TW liable to fail or collapse. This places people at risk of injury and can cause the project to be delayed. The person organising the temporary works needs to be aware of the problems that can occur at each stage of the process and how to prevent these. They need to coordinate design, selection of equipment, appointment of contractors, supervision of work, checking completion, authorisation to load and removal. Unless this is done in a thorough and systematic way problems are likely to occur. If you take this on yourself you must ensure each part of the process is correctly carried out. British Standard 5. TW that has been found to work well on medium and large projects and uses the job title Temporary Works Coordinator TWC. There is no legal requirement to use this job title or the BS recommended process, but you should remember that BS5. Serial Irani Shahrzad. The legal requirement is that the party in control must ensure that work is allocated and carried out in a manner that does not create unacceptable risk of harm to workers or members of the public. On projects with relatively simple TW needs, you may choose not to appoint a TWC. However, you must still make sure that TW are properly managed to ensure safety. Where the situation is small scale and straightforward there may be a standard solution provided for the temporary works TW. These include, for example, use of a tower or system scaffold for access design of a basic access scaffold to a standard configuration using existing data from tables selection of a trench box to support a 2m excavation in firm, dry ground. In each of these cases the person organising the TW will need to assess the ground to be sure it is suitable for the equipment involved, and check that any assumptions made in the calculations for the standard solution are valid for this particular situation and the conditions on site. On a simple job the suppliers data will allow an experienced person to consider the necessary issues without further calculation. Propping using standard equipment such as screw props Acrows needs careful consideration. To select the type, size, number and decide spacing, information is needed about the loads that will act on the props. This will include the wall above and the additional load from any other floor or roof beams etc that enter the wall above or close to the opening. Even with proprietary equipment, the support system must be worked out by a person who knows the correct methods of assessing the loads and designing the support arrangement. Failure of TW is often found to result from the loadings being underestimated and in particular where loadings from the sides are not considered. No.   Temporary works TW can be very sensitive to how they are used and are easily affected by other work taking place nearby. For these reasons the TW designer needs TW training and experience. No.   Coordinating the temporary works TW is not automatically the responsibility of the engineer carrying out the design work. Coordination is a much wider role that includes planning where and when TW will be needed and ensuring that they are correctly installed, used, checked and maintained. Some design engineers may be happy to be additionally contracted to act as project Temporary Works Coordinator.
