The Contractor must use reasonable skill and care in its design and ultimately must carry out the works so as to meet:-
(a) the Board's Construction Requirements;
(b) the Contractor's Proposals (the solution proposed by the Contractor in its tender to meet the Board's Construction Requirements).
The Board may also include optional provisions obliging the Contractor to:-
3.2.1 ensure that the buildings meet the Board's energy efficiency requirements. If, after monitoring this for two years, poor design means these standards are missed, then the Contractor must compensate the Board; and
3.2.2 change its designs or any resulting construction that do not satisfy the Board's Construction Requirements and to ensure that the performance and functionality of the buildings remain at the agreed standard, with the Contractor bearing the cost of these changes.
