ABSTRACT
In the normal contractual arrangement, the engineer provides all the information about the permanent structure. However, on many occasions a temporary structure of some type is needed in order to reach the final position. The design and construction of this is a matter solely for the contractor. In other types of contract, things may be somewhat different. For example, in a direct labour situation the design of all temporary and permanent works is likely to be in the same hands; or the engineer may choose to design the temporary works because of their close interaction with the structure. However, in contracts undertaken under the Institution of Civil Engineers conditions, it is firmly a matter for the contractor, though the submission of details to the engineer is normally required. This submission in no way relieves the contractor-of responsibility, but does provide a further check on practicability and safety.
