Paragraph 17 I1

An officer of the undertaker duly appointed for the purpose may, at any reasonable time and, if required by the Company, under its supervision and control, enter upon and inspect any specified works or any works constructed under this Part of this Schedule.

The approval by the undertaker of any plans, drawings, section 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 undertaker, its officers, servants, or, if not the Company, its contractors or agents) exonerate the Company from any liability or affect any claim for damages by the undertaker.
