ABSTRACT
The great distinction is that the contractor has to show actual loss and expense, rather than secure an adjustment of preliminaries, even though this in itself is far from a straight pro rata. Ascertainment has to proceed from the base established of adjusted preliminaries related to the works as varied, but with the works performed in a regular manner and with costs taken into account, rather than estimated figures in the preliminaries. The present method allows a comparison to be made with the preliminaries to show differences in values and scope. The supplementary agreement for the introduction of the infusion plant had included its own amounts for preliminaries, but had excluded any element of consequential loss and expense on the rest of the works so that, for instance, extra amounts for labour and plant have already been considered. The amounts for preliminaries for the plant had been pitched fairly high, in view of the contractor's strong bargaining position.
