The amount to be charged in the determination should be the
amount that, according to your best judgement, the contractor is
liable to pay. Normally this amount will be calculated by applying

estimated to have been made, by the contractor in that year.
Where there is also information on the cost of materials
involved, this should also be taken into account.
