might appear in the sidewalks for a period of three years; and a set of de- 

 tailed specifications governing the construction of the walks. 



The following are the general conditions of a contract executed by a 

 contractor with the South Park Commissioners, Chicago, for the construc- 

 tion of a number of bridges in 1925. While some of these conditions apply 

 specifically to situations peculiar to this series of construction work, they 

 embody m/DSt of the desirable general principles governing contractual work 

 in general. 



GENERAL CONDITIONS OF THE CONTRACT 



/. Principles and Definitions. 



(a) The contract documents consist of the agreement, 

 the general conditions of the contract, the specifications 

 and drawings for the above-named bridges, including 

 all modifications thereof incorporated in the documents 

 before their execution. These form the contract. 



(b) The term commissioners refers to the South Park 

 Commissioners of Chicago, party to the contract, 

 acting through its duly authorized officers. The term 

 contractor refers to the contractor, party to the con- 

 tract. The term general superintendent refers to the 

 general superintendent of the South Park Commis- 

 sioners, the chief executive officer. The word engi- 

 neer is used in these specifications to designate the chief 

 engineer of the commissioners, or his duly authorized 

 assistant. 



(c) The term subcontractor includes only those hav- 

 ing direct contracts with the contractor and includes 

 one who furnishes material after a special design accord- 

 ing to the plans or specifications of this work, but does 

 not include one who merely furnishes material not so 

 worked. 



(ef) Written notice shall be termed to have been duly 

 served if delivered in person to the individual or to a 

 member of the firm or official of the corporation for 

 whom it is intended, or if delivered or sent by regis- 

 tered mail to the last business address known to him 

 who gives the notice. 



2. Execution, Correlation and Intent of Documents. 



(a) The contract documents shall be signed in dupli- 

 cate by the commissioners and contractor. In case of 

 failure to sign the general conditions, drawings, or 

 specifications, the engineer shall identify them. 



(b) The contract documents are complementary, and 

 what is called for by any one shall be as binding as if 

 called for by all. 



(c) The intention of the contract documents is to 

 include all labor and materials necessary for the proper 

 execution of the work. Any material or labor shown on 

 the plans and not mentioned in the specifications, or 

 vice versa, is to be furnished by the contractor the 

 same as if mentioned in the specifications and set forth 



in the plans. It is the intention of these plans and 

 specifications to obtain materials of the best possible 

 grades for the use for which they are intended. Any 

 material or work described in words which so applied 

 have a well-known technical or trade meaning shall be 

 held to refer to such recognized standards. 



5. Copies of Plans Furnished. 



Unless otherwise provided in the contract documents, 

 the engineer will furnish to the contractor, free of charge, 

 six sets of plans and specifications. All sets required 

 over this number shall be furnished to the contractor 

 at cost. 



4. Shop Drawings. 



The contractor shall submit to the engineer, shop 

 drawings for approval as to correctness of sections and 

 strength of details, with such promptness as to cause 

 no delay in his work, or in that of any other contractor. 

 The engineer will pass on these drawings and details 

 with reasonable promptness, and the contractor shall 

 make any corrections required by the engineer and file 

 with him three corrected copies and furnish such addi- 

 tional copies as may be required in the field. No 

 changes shall be made on any approved shop drawings 

 or construction details without the consent in writing 

 of the engineer. The contractor shall be responsible for 

 the correctness of his drawings and details, as the ap- 

 proval of the engineer is only for general design. Any 

 material ordered by the contractor before approval 

 shall be at his own risk. 



5. Drawings and Specifications on the Work. 



The contractor shall keep one complete copy of all 

 drawings, including shop details or construction details 

 and specifications on the work in good order, available 

 to the engineer and his representatives at all times. 



6. Ownership of Drawings and Models. 



All design drawings and specifications prepared by 

 the engineer and copies thereof are the property of the 

 commissioners. They are to be used on no other work 

 without the written consent of the commissioners, and 

 all copies of plans used by the contractor during the
