Before commencing to construct any authorised work which will involve highway operations, DLRL shall consult the Council as to the time when that work will be commenced, as to the extent of the surface of the highway which it may be reasonably necessary for DLRL to occupy in the construction of that work, and as to the conditions under which that work shall be constructed so as not to cause so far as possible inconvenience to the public and to ensure the safety of the public.
