APPENDIX 253 



11 A*. Discrepancies. In the event of there being any discrepancies 

 between the specification, plans, drawings, or other documents forming 

 the basis of the contract, the specification shall take precedence of and 

 be held to be more correct and binding than the drawings ; and in like 

 manner the figured dimensions on any plans or drawings shall take 

 precedence of and be held to be more correct than the scale affixed to any 

 such plans or drawings ; and in the event of any discrepancies between 

 large-scale and small-scale drawings, the large-scale drawings shall be 

 taken and held to be correct, and shall overrule the small-scale drawings ; 

 and in case of any dispute as to any such discrepancy, or as to the true 

 intent or meaning of the specification, plans, drawings, or other docu- 

 ments forming the basis of the contract, the same shall be determined by 

 the engineer, whose decision shall be final and binding. 



[NoTE. As to the necessity for this clause, see Chap. XI., 9.] 



12. Drawings of foundations. Where foundations are necessary, the 

 contractor shall supply the engineer with drawings of the foundations 

 necessary for his plant, such foundations being provided by the pur- 

 chasers (see Clause 3). The contractor shall insure, by means of tem- 

 plates, the correct position of the foundation bolts and other details. 



13. Defects in contractor's drawings. The contractor shall be respon- 

 sible for any mistake that may arise from any defect in the drawings 

 supplied by him, and for any costs, damages, or expenses which may be 

 sustained or incurred by the purchasers by or in consequence of any 

 such mistake, unless such drawings shall have been approved and signed 

 by the engineer. 



14. Drawings of completed works. Within one month of the taking over 

 of the plant under Clause 41, and of the receipt of a list from the engineer 

 of working drawings of such portions of the plant as may reasonably be 

 required for the future use of those in charge of the works, the contractor 

 shall supply the same at the cost of production. 



15. Subletting of contract. The contractor shall not, without the 

 consent in writing of the engineer, assign his contract, or any substan- 

 tial part thereof, nor underlet the same or any substantial part thereof, 

 nor make any sub -contract with any person or persons for the execution 

 of any portion of the works other than for raw materials, for minor 

 details, or for any part of the work of which the makers are named in 

 the contract. 



[NOTE. As to sub-contractors, see Chap. XVII.] 



16. Approved apparatus. In all cases where plant or apparatus of 

 " approved " type or make is required by terms of the specification, the 

 engineer's approval thereof in writing must be obtained before such 

 plant or apparatus is constructed or ordered, provided that if the con- 

 tractor shall have submitted with his tender drawings of the apparatus 

 which he has included in his tender or otherwise shall have described the 

 same in detail, the engineer shall not have the right to demand other 

 plant or apparatus of a greater value than that so drawn or described. 



17. Notices. All notices to the contractor for the purposes of the contract 

 and these general conditions, shall be sufficiently authenticated if signed by
