98.—(1) An officer of the company duly appointed for the purpose may, at any reasonable time and, if required by the undertaker, under their supervision and control, enter upon and inspect any specified work or any other works constructed under this Part of this Schedule but may not give instructions to any person engaged in or about the specified works except the undertaker or such person as it may from time to time nominate.
(2) The approval by the company of any plans, drawings, sections or specifications or the supervision by it of any work under this Part of this Schedule shall not (if it was done without negligence on the part of the company, its officers, servants, or, if not the undertaker, its contractors or agents) exonerate the undertaker from any liability or affect any claim for damages by the undertaker.
