ABSTRACT
It may be that some offices still adopt this system of taking off and working up as they are commonly called but they cannot be in the majority. In any case there is less need for the preparation of the abstract in civil engineering work as in building. For example, in a school all the painting dimensions for every room are added together on the abstract and stated in the bill as the total for the whole project. In a sewage treatment works, however, the work will usually be presented as a series of locational sub-bills each containing similar items e.g. the Inlet Works, Primary Treatment Tanks will each be billed separately and will contain similar items. The adoption of this system greatly increases the efficiency of the post contract administration.
