APPENDIX 239 



may think proper and sufficient in consequence of such delay, and the 

 contractor shall not make any claim for compensation or damages in 

 relation thereto, and no additions by order of the engineer shall excuse 

 any delay in the completion of the works. 



9. Service of notices, etc. Any notices, instructions, or drawings to be 

 given or furnished to the contractor, shall be deemed to have been duly 

 served or delivered if they shall have been given to the contractor, his 

 foreman, or superintendent personally or left at or sent by post directed 

 to one of them at his usual or last known place of abode or business. If 

 the contractor fail at any time to carry out any instruction given by the 

 engineer under the conditions of this specification, he shall pay to the 

 corporation the sum of 1 for each day during which such instruction 

 remains unexecuted after a sufficient time for its execution has expired. 



10. Additions, omissions, or other deviations from contract. In the 

 execution of his contract the contractor shall make no deviation from 

 the works as herein described or shown on the drawing, with the excep- 

 tion of such deviations as may be ordered by the engineer ; the contractor, 

 however, shall execute any alterations or additional work which may be 

 so ordered by the engineer ; and any work shown on the drawing, or 

 specified in the detailed estimate on this specification, which the engineer 

 shall countermand, shall remain unexecuted ; and the value of such 

 additions, deductions, or other alterations shall be fixed by the engineer 

 according to the detailed estimate, and be deducted from or added to the 

 contract sun\ as the case may require. For any kind of work not specially 

 mentioned in the detailed estimate the price shall be fixed by agreement 

 between the contractor and the engineer before the work is executed, 

 or in the event of any such agreement not being come to, it shall be 

 determined by the engineer only ; but no claim for any extra work will 

 be allowed unless upon vouchers in writing for the same, signed by the 

 engineer. As, however, the engineer or his representative may for some 

 reason give verbal orders for the execution of extra work, the contractor 

 shall, unless he receive written confirmation of such verbal orders, give 

 written notice of his intention to proceed with or of his having com- 

 menced, the work referred to, within one week after such verbal orders 

 are given, and the non-delivery of such notice within the stated time 

 shall be taken as an indication that no extra work has been so ordered. 

 Deviations from the contract shall not extend the time for the completion 

 of the works, unless an extension shall be specially allowed by the 

 engineer. 



11. Material, plant, labour, etc. The contractor shall provide and 

 defray the expenses of the whole of the plant, implements, materials, 

 and labour of every description (except such as are herein specified to be 

 supplied by the corporation), including all requisite dams, temporary 

 pumps and steam engines, tackle, staging, centering, and other tem- 

 porary works required in the execution of, and otherwise in connection 

 with, his contract, and all such temporary works shall be of a sufficiently 

 substantial character for the various purposes for which they are required. 

 The whole of the work shall be finished in the best and neatest manner, 

 to the satisfaction of the engineer, and the labour employed shall be 

 that of properly experienced workmen, and the plant, implements, and
