These estimates are based, as indicated in footnote 13 to paragraph 69 of the report of the Secretary-General, on certain assumptions, including “a 1 January 2003 construction commencement date, escalation of construction project costs at 3.5 per cent per annum during each construction year, a design and planning phase contingency of 20 per cent of the construction project cost, professional costs (for example, architectural, engineering, quality control, project management) of 20 per cent of the construction project cost and a standard construction industry contingency of 5 per cent of construction project cost to cover unanticipated work discovered during actual construction.”
