16.—(1) Subject to the following provisions of this article, the Council may at its own expense and from time to time carry out such protective works to any building within the Order limits as the Council considers to be necessary or expedient.
(2) Protective works may be carried out—
(a)at any time before or during the construction in the vicinity of the building of any part of the authorised works; or
(b)after the completion of the construction of that part of the authorised works, at any time up to the end of the period of 5 years beginning with the day on which that part of the authorised works is first opened for use.
(3) For the purpose of determining how the functions under this article are to be exercised the Council may enter and survey any building falling within paragraph (1) and any land belonging to it.
(4) For the purpose of carrying out protective works under this article to a building the Council may (subject to paragraphs (5) and (6))—
(a)enter the building and any land belonging to it; and
(b)where the works cannot be carried out reasonably conveniently without entering land adjacent to the building, enter the adjacent land (but not any building erected on it).
(5) Before exercising—
(a)a right under paragraph (1) to carry out protective works to a building;
(b)a right under paragraph (3) to enter a building;
(c)a right under paragraph (4)(a) to enter a building or land; or
(d)a right under paragraph (4)(b) to enter land,
the Council shall, except in the case of emergency, serve on the owners and occupiers of the building or land not less than 14 days' notice of their intention to exercise that right and, in a case falling within sub-paragraph (a) or (c), specifying the protective works proposed to be carried out.
(6) Where notice is served under paragraph (5)(a), (c) or (d), the owner or occupier of the building or land concerned may, by serving a counter-notice within the period of 10 days beginning with the day on which the notice was served, require the question whether it is necessary or expedient to carry out the protective works or to enter the building or land to be referred to arbitration under article 54 (arbitration).
(7) The Council shall compensate the owners and occupiers of any building or land in relation to which the powers of this article have been exercised for any loss or damage arising to them by reason of the exercise of those powers.
(8) Where—
(a)protective works are carried out under this article to a building; and
(b)within the period of 5 years beginning with the day on which the part of the authorised works constructed within the vicinity of the building is first opened for use, it appears that the protective works are inadequate to protect the building against damage caused by the construction or operation of that part of the works,
the Council shall compensate the owners and occupiers of the building for any damage sustained by them.
(9) Nothing in this article shall relieve the Council from any liability to pay compensation under section 10(2) of the 1965 Act.
(10) Any compensation payable under paragraph (7) or (8) shall be determined, in case of dispute, under Part 1 of the 1961 Act.
