PARKS 



28. Local Conditions. 



Each bidder shall acquaint himself with all local 

 conditions that may affect work, such as character of 

 soil, means of access, exposure of situation, etc. In- 

 formation of this sort which may be in the possession 

 of the South Park Commissioners, will be given pro- 

 spective bidders by the engineer, but no statements of 

 this character, either verbal or written, shall be con- 

 sidered complete, accurate or binding upon the com- 

 missioners except such as are contained in the attached 

 specifications. 



29. Suneys. 



The engineer will establish on the ground the loca- 

 tions of the center lines of each structure and also 

 locations of the transverse center lines for all structures; 

 he will also establish at each structure at least two 

 permanent bench marks with grades referred to Chicago 

 datum from which center lines and bench marks the 

 contractor shall have all necessary lines, centers and 

 grades established for his work by competent surveyors 

 employed by him. 



30. Black Dirt and Shrubbery. 



Black dirt and other fertile surface soil within the 

 areas occupied by any contractor or handled by him 

 in making excavations or doing grading shall be piled 

 separately in locations selected by the engineer. It 

 shall be protected and shall not be mixed with other 

 material; storage sites will be selected with a view to 

 making rehandling of this soil unnecessary. When other 

 grading work is completed, this soil shall be respread 

 by grading contractor on areas reserved for planting. 

 It shall not be used for subsurface back filling. 



All trees and shrubbery adjacent to the work shall be 

 boxed, fenced or otherwise protected as directed by 

 the engineer. Any trees or shrubbery damaged by the 

 contractor or his employees shall be paid for by him 

 at the full and proper value thereof. 



jz. Contractor's Office. 



The contractor for the work shall provide such offices, 

 tool sheds and other accessories as he may require for 

 his work. His subcontractors shall have the privilege 

 of making reasonable use of such offices and facilities. 



32. Delays. 



If the contractor be delayed in the completion of the 

 work by any act or neglect of the commissioners or of 

 any of its employees, or by any other contractor em- 

 ployed by the commissioners, or by changes ordered in 

 the work, or by strikes, fires, unusual delay of common 

 carriers, unavoidable casualties, or any cause beyond 

 the contractor's control, or by delay authorized by the 

 engineer, or by any cause which the engineer shall de- 

 cide to justify the delay, then the time of completion 

 shall be extended for such reasonable time as the engi- 



neer may decide. No such extension shall be made for 

 delay occurring more than seven days before claims 

 therefor are made in writing to the engineer. In case of a 

 continuing cause of delay only one claim is necessary. 



33. Commissioners' Right to Terminate Contracts. 



The commissioners, upon certificate of the engineer, 

 approved by the general superintendent, that sufficient 

 cause exists to justify such action may, without preju- 

 dice to any other right or remedy and after giving the 

 contractor seven days written notice, terminate the 

 employment of the contractor and take possession of 

 the premises, and of all material, tools and appliances 

 thereon, finish the work by whatever method it may 

 deem expedient, for any of the following reasons: 



(a) If the contractor should be adjudged a bankrupt 

 if he should make a general assignment for the benefit 

 of his creditors, or if a receiver should be appointed on 

 account of his insolvency. 



(b) If he should, except in cases recited in Article 32, 

 persistently or repeatedly refuse or fail to supply enough 

 properly skilled workmen or proper materials. 



(c) If he should fail to make prompt payment tc 

 subcontractors for material or labor. 



(d) If he should persistently disregard laws, ordi- 

 nances or instructions of the engineer. 



(e) If he should be guilty of a substantial violation 

 of any provision of the contract. 



In any such case, the contractor shall not be entitled 

 to receive any further payment until the work is fin- 

 ished. If the unpaid balance of the contract price shall 

 exceed the expense of finishing the work, including the 

 cost of supervision, such excess shall be paid by the 

 contractor. If such expense shall exceed such unpaid 

 balance, the contractor shall pay the difference to the 

 commissioners. The expense incurred by the commis- 

 sioners, as herein provided, and the damage incurred 

 through the contractor's default, shall be certified by the 

 engineer and approved by the general superintendent. 



34. Separate Contracts. 



The commissioners reserve the right to let other con- 

 tracts in connection with this work. The contractor 

 shall afford other contractors reasonable opportunity 

 for the introduction and storage of their materials and 

 the execution of their work, and shall properly connect 

 and coordinate his work with theirs. 



If any part of this contractor's work depends for 

 proper execution or results upon the work of any other 

 contractor, this contractor shall inspect and properly 

 report to the engineer any defects in such work as may 

 render it unsuitable for such execution and results. His 

 failure so to inspect and report shall constitute an 

 acceptance of the other contractor's work as fit and 

 proper for the reception of his work except as to defects 

 which may develop in the other contractor's work after 

 the execution of his work.
