On Chapters 11 - 20: The Contractor will base its costings on a forecast capital replacement programme of plant, machinery, equipment, fixtures, fittings and furniture designed to maintain the building environment at the specified output standards. The Contractor will also consider the means of funding this expenditure throughout the life of the Project. The risk associated with assessing what will need replacing, when and how much this will cost, is one that the Contractor should take and therefore the Authority should not attempt to be prescriptive in this respect.
