progress of the work are to be returned to the com- 

 missioners at the completion of work for which they 

 were issued. All models are to be the property of the 

 commissioners. The ink tracings of all detail drawings 

 made by the contractor and sub-contractors shall be- 

 come the property of the commissioners. 



7. Samples. 



The contractor shall furnish to the engineer samples 

 of all material which he proposes to use in the progress 

 of the work as may be requested by the engineer. After 

 submission and acceptance of samples by the engineer, 

 materials corresponding thereto shall be used through- 

 out the progress of the work. 



8. Engineer Status. 



The engineer, as the representative of the commis- 

 sioners, will have responsible supervision of the con- 

 struction of the work at all times and will make a 

 decision on all claims of the contractor and all matters 

 relating to the execution and progress of the work. All 

 claims of the contractor for extra compensation shall 

 be passed on by the engineer, but before becoming 

 valid, shall receive the approval of the general super- 

 intendent. 



The complete design plans and specifications for the 

 structures, where the foundations for the same and the 

 component parts thereof comprise integral parts of the 

 structure, will be prepared by the engineer. The engi- 

 neer will check, for approval or correctness, the usual 

 detail shop plans for the structural steel work and con- 

 crete bar lists. The engineer will be the interpreter of 

 the plans and specifications prepared by him. 



0. Foremen, Superintendents and Competent Employees. 

 The contractor shall keep on his work, at all times 

 during its progress, a competent foreman or superin- 

 tendent and any assistants that may be necessary. All 

 employees must be satisfactory to the engineer. Men 

 in charge of the work for the contractor shall not be 

 changed except with the consent of the engineer, unless 

 they prove to be unsatisfactory to the contractor and 

 cease to be in his employ. The man in charge shall 

 represent the contractor in his absence and all direc- 

 tions given to him shall be as binding as if given to the 

 contractor. Important directions shall be confirmed in 

 writing to the contractor. Other directions shall be 

 confirmed in writing on request of the contractor. The 

 contractor shall give efficient personal supervision to 

 the work, using his best skill and attention. He shall 

 carefully study and compare all drawings, specifications, 

 and other instructions and shall at once report to the 

 engineer any error, inconsistency, or omissions which 

 he may discover. Any employee of the contractor, who 

 is considered incompetent or careless in his work, shall 

 be, on demand of the engineer, removed and replaced 

 by a competent man. 



10. Materials and Appliances. 



Unless otherwise stipulated, the contractor shall pro- 

 vide and pay for all material, labor, tools, equipment, 

 light, water and power necessary for the prompt exe- 

 cution of the work. All materials shall be new. Both 

 workmanship and material shall be of good quality. 

 The contractor shall, if requested, furnish satisfactory 

 evidence as to the kind and quality of materials. 



Only such material, machinery, tools and imple- 

 ments as are necessary in the prosecution of the work 

 shall be brought on the ground and shall be kept within 

 reasonable limits which shall be designated by the 

 engineer. All condemned material and such as is not 

 suitable for the work shall be promptly removed from 

 the premises, as the work is completed, or as it reaches 

 successive stages of completion and cleaning up is prac- 

 ticable. All rubbish, surplus material, lumber, scaffold- 

 ing, forms, etc., shall be removed from the premises. 

 Earthwork shall be properly graded and disposed of, 

 and the whole work and surroundings shall be left, and 

 at all times maintained, in as neat a condition as is in 

 keeping with the character of the work being done. 



//. Access and Inspection of Work. 



The engineer or his duly authorized assistant shall at 

 all times have free access to the work and shall be 

 entitled to receive from the contractor all necessary 

 information. It is not intended that the contractor 

 shall give out information which is more or less con- 

 fidential in his business and which would divulge any 

 process of manufacture which he is legitimately entitled 

 to keep secret. 



If the specifications, the engineer's instructions, laws, 

 ordinances or any public authority requires any work 

 to be especially tested or approved, the contractor shall 

 give the engineer timely notice of its readiness for in- 

 spection, and, if the inspection is by an authority other 

 than the engineer, of the date fixed for such inspection. 

 Inspections by the engineer shall be promptly made. 

 If any such work should be covered up without approval 

 or consent of the engineer, it must, if so required, be 

 uncovered for examination at the contractor's expense. 



Reexamination of questioned work may be ordered 

 by the engineer. If such work be found in accordance 

 with the contract the commissioners shall pay the cost 

 of reexamination and replacement. If such work be 

 found not in accordance with the contract, through the 

 fault of the contractor or his representatives, the con- 

 tractor shall pay such cost unless he shall show that 

 the defect in the work was caused by another contractor, 

 and in that event the other contractor shall pay the 

 cost. 



Any work that is rejected by the engineer or his 

 representatives shall be torn down and replaced at the 

 contractor's expense. Any work so condemned shall be 

 replaced with reasonable promptness by this contractor.
