The Contractor shall at least twenty (20) Business Days before the date on which the Contractor first [carries out any of the Works or]156 provides any of the Services provide the Authority with a written list of the names and addresses of all employees or other persons who it expects may require admission to [the/each] Site[s] in connection with the [carrying out of the Works] or provision of the Services, specifying the capacities in which those employees or other persons are concerned with the [Works or] Services and giving such other particulars as the Authority may require. The Contractor shall update this information as and when any such individuals are replaced or complemented by others, not less than twenty (20) Business Days before their inclusion. The decision of the Authority on whether any person is to be refused admission to [the/a] Site[s] shall be final and conclusive and the Authority shall not be obliged to give reasons for its decision. For the avoidance of doubt, the provisions of this clause 31.4 (Admission to the Site[s]) shall not apply to those individuals who shall be required by the Contractor or any relevant sub-contractor to attend [the/on] Site to provide emergency reactive services. In the case of such individuals, the Contractor shall or shall procure that any relevant sub-contractor shall ensure that such individuals are accompanied at all times while on [the/each] Site[s] by a member of the Contractor or relevant sub-contractor's staff who has been properly notified to the Authority in accordance with the terms of this clause 31.4 (Admission to the Site[s]).
