SPECIFICATIONS. GENERAL. Location of Work. (1) The Sanitary District of Chicago has now under construction what is known as The North Side Sewage Treatment Works, with adjuncts thereto, upon property owned by the Sanitary District situated immediately north of Howard Avenue and west of the North Shore Channel of the Sanitary District, in the Vil- lage of Niles Center, County of Cook, State of Illinois. The Pump and Blower House, with appurtenances, to be constructed under this contract is a building containing the pumps, blowers and other machinery and the electrical and other equipment required for pumping sewage to the treatment works from certain intercepting and collecting sewers that enter the easterly end of the Pump and Blower House, and for providing compressed air and electrical power of suitable voltage to the other parts of the treatment works. The Barb and Blower Houkou is to be ante east of the treatment works adjoining the north side of Howard Avenue between the tracks of the Chicago and North Western Railway May- fair Cut-off on the west and the new McCormick 68 Road, also being constructed by the Sanitary District, on the east. A subway under the rail- way tracks is to be built by the Sanitary Dis- trict for McCormick Road under another con- tract and will be located at a point approxi- mately 1,300 feet north of the Pump and Blower House as shown on Sheet C1 of the accompanying plans. Work Included. (2) The work included under this con- tract consists of furnishing all material, labor, tools and equipment necessary and constructing and completing the entire Pump and Blower House, furnishing and installing all machinery and mechanical, electrical and other equip- ment therein that is specified to be furnished and placed by the Contractor, installing all ma- chinery, devices, equipment and parts that are specified to be furnished by the Sanitary District or by other contractors and installed by the Contractor hereunder, and performing all other work shown on the accompanying plans or specified under the several items of work hereunder, all in accordance with such plans and these specifications and the terms and conditions of this contract and the orders of the Engineer hereunder. Contract Drawings. (3) The work under this contract includes all the work embraced by these specifications and the accompanying plans which are made a part hereof. In the event of any discrepancy between the plans and these specifications, the decision of the Engineer shall be final thereon. 69 The figured dimensions on the plans are to be taken as correct, but the Contractor is required in addition to carefully check all dimensions given on the accompanying plans and on all additional plans that are furnished by the Sanitary District, before ordering any material or beginning any work shown thereon. Should any errors be discovered, the Engineer’s atten- tion shall be called to the same and the proper corrections made. All notes on the plans shall be carefully observed by the Contractor, and are made a part of the contract. All elevations shown on the plans or herein specified are re- ferred to Chicago City Datum (C. C. D.) Additional plans furnished by the Sanitary District for the work hereunder shall be sub- ject to the same conditions as herein before specified for the plans accompanying this con- tract. Construction conditions may require that minor changes be made in the location and installation of the equipment to be furnished and other work to be performed hereunder, and the Contractor, when ordered by the En- gineer, shall make such adjustments and changes in said locations and work as may be necessary without additional charge, provided such adjustments and changes do not unrea- sonably alter the character, quantity or cost of the work as a whole, and provided further that plans and specifications showing such ad- justments and changes are furnished the Con- tractor by the Sanitary District within a reason- able time before any work involving such ad- justments and changes is begun. 70 Drawings and Information to be Furnished by the Contractor. (4) Within sixty (60) days after the ap- proval by the Board of Trustees of the Sanitary ‘District of the bond of the Contractor, the Con- ‘tractor shall submit to the Engineer, for ap- proval, general drawings or prints in duplicate of the equipment furnished under this contract and the foundations for same, together~ with all other information necessary to permit the ‘Engineer to inform himself of the design of the same and the character of the various mate- rials which the Contractor proposes to use.

Transformer—Detail blue prints For work under Items 1 and 2 the Contractor shall submit to the Engineer for his approval at least fifteen (15) days before commencing work thereon, a statement of the procedure, methods and equipment the Contractor pro- poses to employ on the work under these itemy The Contractor shall make such changes in the above drawings as may be found necessary upon inspection by the Engineer to make the same conform to the specifications and plans at his own expense, and revised drawings shall then be submitted in quadruplicate for ap- proval. Prior to the approval of any such draw- ings any work which the Contractor may do on the equipment covered by the same shall be at his own risk, as the Sanitary District will not be responsible for any expense incurred by the Contractor in changing equipment to make the same conform to the drawings as finally approved. The Contractor shall furnish to the Engineer a tabulated list of the minor equipment for which drawings may not be required, showing the name of the manufacturer and the catalog number and type of equipment proposed, to- gether with such prints, dimensions, specifica- tions, samples, or other data, as may be required to permit intelligent judgment of the accept- ability of the same. Upon approval of the above drawings, prints, lists, samples and other data, the same shall become a part of this contract, and the equip- ment furnished shall be in conformity with the same; provided, that the approval of the above drawings, prints, lists, specifications, samples or other data shall in no way release the Contractor from his responsibility for the proper fulfillment by any equipment, of the re- quirements of this contract and of the purpose 74 for which said equipment is installed, nor from his liability to replace the same should it prove defective. Force and Plant. (5) Attention is called to the fact that Divi- sion P, Pump and Blower House, to be con- structed hereunder is a necessary and important part of the North Side Sewage Treatment Works other parts of which are now under construc- tion by the Sanitary District under other con- tracts. The Sanitary District will therefore require that the work to be performed here- under shall be prosecuted with all speed, and with the least possible inconvenience to the public and to other contractors engaged on work for the Sanitary District. It is therefore understood and agreed that the largest possible force of men and maximum possible plant that can reasonably be employed shall be used on the work under this contract. The decision of the Engineer as to what is a reasonable force of men and a reasonable plant shall be final and binding upon both parties to this contract, and the Contractor shall increase his force or plant whenever the Engineer shall determine it is necessary for the progress re- quired for completion within the time herein specified and shall direct him in writing to do so. Co-operation with Other Contractors. (6) The attention of the Contractor is specifically called to the fact that there is now under contract the work of constructing Mc- Cormick Road and a subway in connection 75 therewith under the C. & N. W. Ry.; and also a contract for the construction of a 36-inch main drain from the main portion of the treat- ment plant across the site of the work here- under and the plans and specifications therefor will be shown said Contractor on request. The Contractor’s attention is also called to the fact that additional contracts will be awarded by the Sanitary District for the construction of various sewers, tunnels, conduits and other overhead and underground structures at and in the vicinity of the site of the work hereunder, details of which work will be given the Con- tractor on request. The Contractor hereunder shall arrange and conduct his work so as not to interfere with or damage said work and structures. As the work progresses, from time to time, other contracts will be let, for the work above described in this section which work will partly overlap on the site of, and will be carried on simultaneously with the work to be performed under this contract and will cause some in- terference therewith. The Contractor shall co- operate with other contractors by promptly f fur- nishing and placing such labor, material and equipment called for under this contract, or by removing materials or equipment from the loca- tions where stored, wherever necessary to in- sure against delay in the prosecution of other contracts, and shall so arrange his work as to cause a minimum of interference with the work of other contractors. 7 Wherever the terms “C. & N. W. Ry.” “*C. & N. W. Ry. Co.” or “The Railway Sig hae are mentioned herein they shall be understood 76 to mean the Chicago and North Western Rail- way or the Chicago and North Western Rail- way Company. Ground Elevations and Test Pits. (7) Elevations of the ground are shown on the plans hereto attached. These elevations are believed to be reasonably correct, but are not guaranteed to be absolutely so, and to- gether with any schedule of quantities, are pre- sented only as an approximation. Samples from test pits are on file in the Engineer’s office for the information of the Contractor, but are not guaranteed. The Contractor must satisfy him- self regarding the character and amounts of peat, clay, sand, quick-sand, gravel, glacial drift, rock and other material to be encoun- tered and work to be performed. Space for Material and Plant. (8) The Contractor shall have the use of space on unoccupied and unused property of the Sanitary District adjacent to or near the site of the work, for the storage of material and for plant and equipment, subject to the ap- proval of the Engineer. All other necessary storage facilities shall be provided by the Con- tractor. The Contractor shall not use or oc- cupy any property not owned or controlled by the Sanitary District without the consent of the owners or lessees of such property and shall assume all liability for and pay all costs, damages and expenses that may be due to or grow out of the use or occupation of such property by the Contractor. 17 The Contractor shall not occupy or use any space in McCormick Road or in the ditches or on the side slopes of the approaches to the subway under the C. & N. W. Ry., nor where any work on McCormick Road or the subway or approaches thereto or any other work of the Sanitary District is being performed, without the permission of the Engineer so to do and subject to all conditions and restrictions as he shall impose for such occupation or use. It is understood and agreed that whenever necessary to permit the performance of any work by the Sanitary District or other contrac- tors, or by the C. & N. W. Ry. Co., the Con- tractor hereunder shall move or remove, upon the order of the Engineer so to do, any mater- ial, equipment or plant that is located upon space required for the performance of such work. The Contractor shall receive no com- pensation for moving same if the Engineer shall decide that such material, equipment or plant is no longer required for the work hereunder, or if such material, equipment or plant has been placed in such locations without the ap- proval of the Engineer. Provisions for Delivery of Material and Equipment. (9) The Contractor shall provide and maintain all temporary roads, walks, switch tracks and other means of access to the site which may be necessary for performing the work herein specified. The Contractor shall not use McCormick Road at any time before it is opened for public traffic. Use of McCormick Road where opened for public traffic shall be subject 78 to all established regulations of the Sanitary District for such use and the requirements of the Engineer for the proper protection of the shoulders and of the edges of the pavement. All damages to McCormick Road that may occur due to or resulting in any way from the work under this contract shall be repaired by the Contractor in a manner scare: by ohe Engineer. . Except as hereinafter otherwise specified the Contractor shall provide -and. maintain or pay for the use of all switch tracks, sidings and other tracks and facilities required or used for delivery of material or equipment -to and ship; ment of same from the work hereunder. Switch Tracks and Sidings. (10) shall be removed by the Contractor. Hand-Mixing. (C56) Hand-mixing of small amounts only of concrete may be authorized by the Engi- neer in emergencies where a mixer is not rea- sonably or immediately available. When so authorized by the Engineer it shall be done on a water-tight platform. The cement and fine aggregate shall first be mixed dry until the whole is a uniform color. The water and coarse aggregate shall then be added and the entire mass turned at least four (4) times, or until the specified homogeneous mixture of the required consistency is obtained. Not more than one-half yard of concrete shall be mixed in any batch unless expressly permitted by the Engineer. Retempering. (C57) Concrete shall be mixed in such quantities that any batch can be placed in the work within 30 minutes after the time of mix- ing. The retempering of concrete or mortar which has partly hardened, that is, remixing with or without additional cement, aggregate or water, will not be permitted. 126 DEPOSITING CONCRETE General. (C58) Before beginning a run of concrete, all hardened concrete and foreign materials shall be removed from the inner surfaces of the mixing and conveying equipment. Before depositing concrete, all debris and loose material shall be removed from the space to be occupied by the concrete; forms shall be thoroughly wetted (except in freezing weather) or oiled as specified. Reinforcement shall be rigidly secured in position and ap- proved by the Engineer. The bottoms of forms of beams, girders and slabs shall be coated with mortar as hereinafter specified before concrete is placed therein. Under encased steel beams, concrete containing no large pieces of coarse aggregate shall be used. Handling. (C59) Concrete shall be handled from the mixer to the place of final deposit as rapidly as practicable by methods which prevent the separation or loss of any of the ingredients. It shall be deposited in the forms as nearly as practicable in its final position to avoid rehan- dling. It shall be so deposited as to maintain until the completion of the unit, a plastic sur- face approximately horizontal. Forms for walls, columns and other thin sections of con- siderable height shall be provided with open- ings, or other devices, that will permit the con- crete to be placed in a manner that will avoid accumulations of hardened concrete on the forms or metal reinforcement. Under no cir- 127 cumstances shall concrete that has partly hardened be deposited in the work. Chuting. (C60) When concrete is conveyed by chuting, the plant shall be of such size and design as to insure a practically continuous flow in the chute. The angle of the chute with the horizontal shall be such as to allow the concrete to flow without separation of the ingredients. The delivery end of the chute shall be as close as possible to the point of deposit. When the operation is intermittent, the spout shall discharge into a hopper. The chutes shall be flushed thoroughly with water before and after each run and the water used for this purpose shall be discharged outside the forms but not where it will cause softening of any material beneath the footings or upon which concrete is to be placed. Compacting. (C61) Concrete, during and immediately after depositing, shall be compacted thorough- ly by means of suitable tools. For thin walls or inaccessible portions of the forms, where rodding or forking is impracticable, the con- crete shall be assisted into place by tapping or hammering the forms opposite the freshly de- posited concrete and the concrete shall be worked thoroughly around the reinforcement, and around embedded fixtures, and into the corners of the forms. (See Surface Finish, Sections (C97) to (C104) inclusive.) 128 Removal of Water. (C62) In order to obtain clean and firm bearing surfaces all water and softened mate- rial shall be removed from excavations im- mediately before concrete is deposited. Con- crete shall not be deposited in water nor shall water be allowed to rise over the concrete until it has been hardened sufficiently to pre- vent injury thereto. Any flow or water into the excavation shall be diverted through proper side-drains to a sump, or shall be removed by other approved methods which will avoid washing the freshly deposited concrete. Water vent pipes and drains shall be filled by grout- ing, or other means approved by the Engineer, after the concrete has thoroughly hardened. Salts, Chemicals and Admixtures. (C63) Salts or chemicals shall not be added to concrete for any purpose whatsoever. The use of admixtures or integral waterproofing compounds will be permitted only subject to the approval of the Engineer and without ad- ditional charge therefor to the Sanitary Dis- trict. Depositing Continuously. (C64) Concrete shall be deposited contin- uously and as rapidly as practicable until the beam, slab, wall section or other unit of opera- tion, approved by the Engineer, is completed. Construction joints not provided for in the plans shall be made in accordance with the provisions of Sections (C90) to (C96) inclusive and subject to the approval of the Engineer. 129 Bonding. (C65) Before depositing new concrete on or against concrete which has set, the forms shall be retightened, the surface of the hardened concrete shall be roughened as re- quired by the Engineer and _ thoroughly cleaned of foreign matter and laitance. The new concrete placed in contact with hardened or partly hardened concrete, shall contain an excess of mortar to insure bond. To insure this excess mortar at the juncture of the hard- ened and the newly deposited concrete, the cleaned and saturated surfaces of the hard- ened concrete, including horizontal, vertical and inclined surfaces, shall first be slushed with a coating of neat cement grout or of mortar against which the new concrete shall be placed at once before the grout or mortar has attained its initial set. (See Joints, Sec- tions (C90) to (C96) inclusive.) Protecting Surfaces. (C66) The surfaces of concrete and mortar that will be exposed to the sun or to premature drying after placing shall be kept. constantly moist by sprinkling at frequent intervals. or by covering with moist burlap or canvas, or by other means equally effective, approved by the Engineer, for a period of seven (7) days after completion. Freshly finished surfaces not covered by forms shall be protected by supported canvas during rain storms and a sufficient quantity of canvas shall be kept ready for this purpose. 130 Reinforcement. (C67) Before placing concrete the rein- forcement bars in the slabs and beams and other sections shall be examined in detail and checked and all displacements corrected and all bars supported and wired so that movement will not occur during the deposit- ing of concrete around them. All bars shall be located as shown on the plans, provided that none shall be imbedded a clear distance of less than one diameter of the bar from the face of the concrete and not less than three- quarter (34) inch in slabs and one and one- half (116) inches in beams and girders. Setting Fixtures in Concrete. (C68) Before placing concrete all con- duits, frames, castings, hangers, anchors, bolts and other fixtures that are to be imbedded therein, shall be properly placed and _ sup- ported and all of same and all openings in floors and walls shall be checked for posi- tion, alignment and elevation. They shall be checked against displacement from time to time as the concrete is deposited thereafter and any displacements found at any time shall be corrected by the Contractor without additional charge therefor to the Sanitary District. Depositing Concrete Under Water. (C69) Under no conditions shall concrete be deposited in water nor shall water be al- lowed to rise upon freshly deposited concrete or upon concrete that has not sufficiently hard- 131 ened to avoid all possibility of damage thereby, as determined by the Engineer. Cofferdams and Sheeting. (C70) Cofferdams and sheeting shall be sufficiently tight to prevent the flow of water into the space in which the concrete is de- posited. Laitance. (C71) Great care shall be exercised to avoid the formation of laitance. On com- pleting a section of concrete, the laitance and all loose and unsound concrete shall be en- tirely removed before work is resumed. CONCRETING IN FREEZING WEATHER. Conditions for Concreting in Freezing Weather. (C72) Concrete work shall not be _ per- formed in freezing weather or when freezing weather is forcast by the U. S. Weather Bureau to occur within 36 hours, except with the express written permission of the Engineer and not unless special precautions and meas- ures are taken to heat the aggregates and the water used, or such of same as the Engi- neer may direct, and to protect the concrete after placing until it shall have so sufficiently set that it will not be damaged by freezing. Enclosures. (C73) If concrete work of material amount is to be performed in winter, it shall be en- closed above and below and on all! sides and 132 heated within the inclosure to temperatures that will permit the concrete to obtain proper set and will prevent any freezing. Temperature and Heating. (C74) Salts or chemicals shall not be used in concrete to retard freezing. The tempera- ture of the concrete when it is placed in the work shall not be less than fifty (50) degrees Fahrenheit and measures approved by the Engineer shall be taken to keep the concrete | well above freezing temperature until it has attained its final set. The frost shall be re- moved from all material with which the fresh concrete will be in contact when placed in the work. The methods of heating aggregates shall be such that they will be heated as uniformly as possible throughout. Aggregates contain- ing frozen lumps shall not be used. The de- gree or amount of heating of water and ag- gregates will depend upon temperature and weather conditions and shall be as the Engi- neer shall direct. Protecting after Placing. (C75) In case freezing weather occurs during the placing of concrete or before the concrete has acquired a sufficient set to prevent damage from freezing, the concrete must be immediately protected by the Contractor in a manner approved by the Engineer and the pro- tection or protective measures shall be main- tained until final set has’ been obtained, as determined by the Engineer. 133 Payment for Concreting in Freezing Weather. (C76) All material, labor and equipment employed to prevent or to protect against freezing and to remove all protections and equipment thereafter, shall be furnished by the Contractor without extra charge for same and no additional payment will be made there- for.

Workmen. Art. 18. The Contractor shall employ com- petent foremen and laborers, and shall dis- charge, at the request of the Engineer, any in- competent or unfaithful men in his employ. None but men expert in their respective branches of work shall be employed where spe- cial skill is required. Sanitation. Art. 19. In accordance with the rules and. regulations for the guidance of Sanitary In- spector, etc., adopted by the Board of Trustees on July 31, 1913, page 997 of the Proceedings for 1913, the Contractor shall introduce and en- force among his employees such regulations in regard to cleanliness and the disposal of gar- bage and wastes, as shall conduce to their health, and tend to prevent the inception and spread of contagious and infectious disease among them, and shall take such means as the Engineer may direct to effectually prevent the creation of a nuisance on any part of the prop- erty of said Sanitary District or adjacent streets, or property. Necessary sanitary con- veniences for the use of the laborers on the work, properly secluded from public observa- tion, shall be constructed and maintained by the Contractor in such manner and at such points as shall be approved, and their use shall be strictly enforced. 597 Patents. Art. 20. It is further agreed that the Con- tractor shall indemnify, keep and save harmless said Sanitary District from all liabilities, judg- ments, costs, damages and expenses which may in any wise come against said Sanitary District, by reason of the use of any patented material, machinery, devises, equipment or processes fur- nished by the Contractor and used in the performance of the work under this con- tract, or by reason of the use of patented designs furnished by the Contractor and accepted by the Sanitary District except- ing only the siphon spillways located in the southwest corner of the building. In the event any claim, suit or action at law or in equity of any kind, whatsoever, is made or brought against said Sanitary District involving any such patents, then the Sanitary District shall have the right to retain from the money due and to become due said Contractor a suffi- cient amount of money to protect itself against loss in the same manner and upon the same conditions as hereinafter specified in the next following article of this contract. Damages. Art. 21. Said Contractor covenants and agrees to pay all damages for injury to real or personal property, or for any injury sustained by any person growing out of any act or deed of said Contractor, or of his employees, that is in the nature of a legal liability, and he hereby agrees to indemnify and save the Sanitary Dis- trict harmless against all suits and actions of every name and description brought against 598 said Sanitary District for, or on account of any such injuries to real or personal property, or injuries received or sustained by any person or persons, caused by said Contractor, his servants, agents or employees, in the execution of said work; or by or in consequence of any negli- gence in guarding the same; or by or on ac- count of any omission or act of said Contractor, his agents or employees; and the said Con- tractor further agrees that so much of the money due him under and by virtue of this con- tract, as shall be considered necessary by the Board of Trustees of said Sanitary District, may be retained by the Sanitary District to protect itself agains{ loss until such suit or claim for damages shall have been settled, and evidence to that effect shall have been furnished to the satisfaction of the said Board of Trustees. Employers’ Liability Act. Art. 22. The Contractor further agrees to insure to his employees or their beneficiaries and to the employees or the beneficiaries of any subcontractor employed by him on said work the necessary first aid, medical, surgical and hospital services, and the compensation pro- vided for in the Workmen’s Compensation Acts of the General Assembly of the State of Illinois as amended and now in force. Said Contractor hereby further agrees to in- demnify, keep and save harmless said Sanitary District from all claims, judgments, awards and costs which may in any wise come against said Sanitary District by reason of any accidental injuries or death suffered by any of his em- ployees or the employees of any subcontractor 599 employed by him in and about the performance of the work under this contract. Such insurance shall be placed by said Con- tractor in a company or association authorized under the laws of the State of Illinois to insure the liability above specified or in lieu of such insurance said Contractor or subcontractor hereby agrees to guarantee his liability to pay the compensation provided for in said Acts as amended and now in force. Responsibility of Contractor. Art. 23. The Contractor shall be responsible for the entire work until completed and ac- cepted by the Sanitary District. The Con- tractor shall give his personal attention to the fulfillment of this contract and to the execution of the work. He shall keep the same under his control, and shall not sublet any part of it, ex- cept as hereinafter specified. The Sanitary District will not recognize any parties engaged on the work covered by this contract other than the Contractor and his employees. The Contractor shall not assign by power of attorney or otherwise any portion of the moneys that may become due through the per- formance of the work under this contract or any part thereof. Subletting Work. Art. 24. The Contractor shall not sublet any part of the work herein mentioned to any per- son or corporation that is not, in the opinion of the Engineer, competent, experienced and financially able to properly carry out and ex- 600 ecute the same, and in the event that said Con- tractor desires to sublet any part of the work he shall, prior to such subletting, submit to the Engineer a statement showing the character of the work and the party or parties to whom it is proposed to sublet the same, and his or their experience, financial ability and other qualifica- tions for properly carrying out and completing the same and the decision of the Engineer as to said qualifications, financial ability, experience and competency shall be final and binding upon both parties hereto. It is further understood and agreed that such subletting, or the ap- proval thereof by the Sanitary District or by the said Engineer, shall not directly or indi- rectly release or modify the responsibility of the Contractor for the satisfactory and entire completion of said work and each and every part and portion thereof, and that said Sani- tary District shall not be liable to any subcon- tractor for any lien on the structures to be built hereunder or claim on the moneys due the Con- tractor or any other lien, claim or damages whatsoever. In case any party or parties, to whom any work under this contract shall have been sublet, shall disregard the directions of the Engineer or his duly authorized representa- tives, or shall furnish any unsatisfactory work, or shall fail or refuse in any way to conform to any of the conditions of this contract, then in that case, upon the written order of the Engi- neer, the Contractor shall require said party or parties in default to discontinue work under this contract. Any defective work done by any such subcontractor shall be replaced by work which is satisfactory to the Engineer. 601 Liens. Art. 25. If at any time during the progress of said work the said Contractor shall fail or - neglect to pay for any labor performed, mate- rial furnished, or tools, machinery, appliances, fuel, provisions or supplies of any sort or kind used or consumed in, upon, or on account of said work for ten (10) days after payment for same shall have become due, then the said Sanitary District shall have the power to pay for such labor or for materials, tools, machin- ery, appliances, fuel, provisions, or supplies, and the amount so paid shall be retained out of the money due or to become due to said Con- tractor. The said Sanitary District may refuse to make payment hereinafter mentioned to the extent of such indebtedness until satisfactory evidence in writing has been furnished that said indebtedness has been discharged. In any — such case, said Sanitary District is hereby au- thorized and empowered by said Contractor to ascertain by the Engineer the amount due or owing from said Contractor to any laborer or laborers, or to any person or persons, or cor- poration, for labor, equipment, material, tools, machinery, appliances, fuel, provisions or sup- plies of any sort or kind consumed upon, in or on account of the work covered by this contract in such manner and upon such proofs as the said Engineer may deem sufficient. Co-operation. Art. 26. It is understood and agreed that all work shall be executed in such manner and in such order or procedure as will permit of the commencement and carrying on of work of the 602 Sanitary District and of other contractors with the least interference possible under a reason- able procedure whenever it is necessary or de- sirable to prosecute said work, either simul- taneously with the work under this contract or otherwise. To this end the Contractor shall co- operate with and assist the Sanitary District and other contractors in every reasonable way and shall interfere as little as possible with their work. The Contractor shall so arrange his work, plant and equipment that work of the Sanitary District and of other contractors for the Sanitary District shall not be made in- accessible at any time and can be performed without unnecessary or unreasonable expense on account of the work, plant or equipment of the Contractor, hereunder. The Contractor shall move, free of charge, his plant and equip- ment or any part of same whenever the Engi- neer shall consider it reasonable and necessary for the work of the Sanitary District or other contractors. The Contractor when requested by the Engineer shall also furnish the Sanitary District and other contractors with material and with the use of plant and equipment of the Contractor at reasonable rates therefor, when- ever, in the opinion of the Engineer, such use of such plant and equipment will not unreason- ably delay or interfere with the work under this contract. The Contractor shall not be entitled to any damages or to any anticipated profits on work dispensed with or to any extra compensation from the Sanitary District on account of any work performed by the Sanitary District, or other contractors, that is contemplated in these 603 specifications or on the plans or that is neces- sary for carying on or completing or that in any way affects the work under this contract, pro- vided that such work of the Sanitary District and other contractors, in the opinion of the Engineer, is performed in a proper and ex- peditious, or a necessary manner. The Engi- neer shall decide all questions between the Contractor and the Sanitary District or other contractors, and the order of carrying on the work shall always be subject to the Engineer’s direction and approval. His decision upon all questions relating to this contract shall be final and binding upon both parties hereto. In case the Contractor, by his own acts or the acts of any person or persons in his em- ploy, shall unnecessarily delay, in the opinion of the Engineer, the work of the Sanitary Dis- trict or other contractors by not properly co- operating with them, or affording them suffi- cient opportunity or facilities to perform work, as hereinbefore specified, the Contractor shall, in that case, pay all costs and expenses in- curred by such parties, due to any such de- lays, and hereby authorizes the Sanitary Dis- trict to deduct the amount of such costs and expenses from any moneys due or to become due under this contract. The Engineer shall decide the extent of such delay or delays and amount of such costs and expenses, and his de- cision shall be final and binding upon both parties to this contract. Nothing contained in this paragraph shall, however, relieve said Contractor from any liability or damages re- sulting to the Sanitary District on account of such delay or delays. 604 Time. Art. 27. The Contractor agrees to begin the work covered by this contract within thirty (30) days from the date of the approval by the Board of Trustees of said Sanitary District of the bond of said Contractor, and to prose- cute the same with all due diligence and to en- tirely complete the work on or before January 1, 1928. It is understood and agreed that TIME is the essence of this contract, and that a failure on the part of said Contractor to complete the work herein specified within the time specified will result in great loss and damage to said Sanitary District, and that on account of the peculiar nature of such loss or damage it is difficult, if not impossible, to accurately ascer- tain and definitely determine the amount thereof. Liquidated Damages. Art. 28. It is therefore covenanted and agreed that in case the said Contractor shall fail or neglect to complete the work herein specified on or before the date hereinbefore fixed for completion, the said Contractor shall and will pay the said Sanitary District the sum of THREE HUNDRED FIFTY DOLLARS ($350.00) for each and every day the Con- tractor shall be in default in the time of com- pletion of this contract. Said sum of THREE HUNDRED FIFTY DOL- LARS ($850.00) per day is hereby agreed upon, fixed and determined by the parties hereto as liquidated damages which said Sanitary Dis- 605 trict will suffer by reason of such defaults and not by way of a penalty. In case the said Con- tractor does not complete the work covered by this contract on or before the time specified herein for the completion of the said work, the Engineer shall decide the number of days the said Contractor is in default, and the decision of said Engineer shall be final and binding upon both parties hereto. It is further agreed that if said Sanitary Dis- trict shall accept any work or make any pay- ments under this contract after any such de- fault, such acceptance, payment or payments shall not in any respect constitute a waiver or modification of any of the provisions hereof, and particularly the provisions in regard to TIME and LIQUIDATED DAMAGES for de- lays. Extensions or Additions. Art. 29. In the event that any material alter- ations or additions are made as herein speci- fied, which, in the opinion of the Engineer, will require additional time for the execution of any work under this contract, then in that case the time of the completion of the work shall be extended by such a period of time as may be fixed by said Engineer, and his decision shall be final and binding upon both parties hereto, provided that in such case the Contrac- tor, within four (4) days after being notified in writing of such alterations or additions, shall request in writing an extension of time, but no extension of time shall be given for any minor alterations or additions, and the provi- sions of this article shall not otherwise alter, 606 change or invalidate the provisions of this con- tract with reference to LIQUIDATED DAM- AGES, and the said Contractor shall not be en- titled to any damages or compensation from the said Sanitary District on account of such additional time required for the execution of the work. Notice to Suspend Work. Art. 30. The Contractor shall delay or sus- pend the progress of the work, or any part thereof, whenever he shall be so required by written order of the Engineer, and for such pe- riods of time as the Engineer may order, pro- vided that in the event of such delay or delays or of such suspension or suspensions of the progress of the work or any part thereof, the time for the completion of the work so sus- pended or of work delayed by such suspen- sions, shall be extended for a period equivalent to the time lost by reason of such suspension or suspensions, but such order of the Engineer shall not otherwise modify or invalidate in any way any of the provisions of this contract, and said Contractor shall not be entitled to any damages or compensation except as mentioned in Article 31, from the Sanitary District on ac- count of such delay or delays, suspension or suspensions. Unavoidable Delay. Art. 31. Should the Contractor be obstruct- ed or delayed in the commencement, prosecu- tion or completion of any part of said work by any act or delay of the Sanitary District, or by any act or delay on the part of railroads in 607 furnishing cars or transporting any equipment, material or appurtenances for said work, or by riot, insurrection, war, pestilence, acts of public authorities, fire, lightning, earthquake, cyclone, floods, or through any default or de- lay of other parties under contract with said Sanitary District, or due to strikes, or to other causes, which causes of delay mentioned in this article (Art. 31), in the opinion of the Chief Engineer are entirely beyond the control of the Contractor, then the time herein fixed for the completion of the work so delayed shall be ex- tended for a period equivalent to the time lost be reason of any cause aforesaid, but no such allowance shall be made unless the Contractor notifies the Engineer before the fifth of each succeeding month of all delays occurring in the preceding month. It is further expressly agreed that said Con- tractor shall not be entitled to any damages or compensation from the said Sanitary Dis- trict on account of any delays resulting from any of the causes above specified in this ar- ticle (Art. 31), except compensation for wages for extra time for any necessary watchmen and for extra premiums of his bond, actually paid by said Contractor, on account of said addi- tional time so required to complete all work hereunder, due only to delays caused by the Sanitary District or by other parties under con- tract with said Sanitary District. The Chief Kingineer shall decide the number of days that said Contractor has been so delayed and his decision shall be final and binding upon both parties hereto. 608 Forfeiture of Contract. Art. 32. It is further agreed by and between the parties hereto that if said Contractor fails financially, or abandons this contract, or fails, refuses or neglects to fully complete said work within the time specified, or as extended under the terms of this contract, or if in the opinion of the Chief Engineer said work has been or is being delayed by said Contractor so that said work cannot be completed within the time specified, or as so extended, or if from any other cause, whatsoever, said Contractor is un- able to carry out the terms and conditions of this contract and complete said work, or if said Contractor shall sublet, in whole or in part, the work under this contract without the consent of the Sanitary District first had and obtained, then said Sanitary District may declare his contract forfeited either as to a portion of the same or the whole thereof. Upon the happening of any of the conditions hereinbefore in this section specified, the said Sanitary District shall have a lien upon all the materials, supplies, machinery, implements and tools of the Contractor for the purpose herein- after specified; and the said Sanitary District may thereupon immediately take possession of all said materials, supplies, machinery, imple- ments and tools, for the uses and purposes hereinafter set forth; thereupon the said Sani- tary District shall have the power to, and may at the cost of said Contractor, complete the said work by letting a new contract, and in completing the said work by contract, the said Sanitary District may use such materials, sup- plies, machinery, implements, tools and plant 609 as may be the property of said Contractor, and make the necessary repairs and replacements thereto. _ The cost of fully completing all the work provided for under any new contract shall in- clude the sum or sums of money paid by the Sanitary District to other contractors and all cost of repairs and replacements upon machin- ery, implements, tools and plant of the Con- tractor hereunder and also all sums of money paid for first aid, medical, surgical and hospi- tal services and compensation for accidental injuries or death suffered by the employes of any new contractor in the course of their em- ployment in completing said work under the Workmen’s Compensation Acts of the General Assembly of the State of Illinois, now in force. The cost and expense of fully completing said work as aforesaid, shall be charged to the Contractor and the amount of such cost or ex- pense so charged shall be deducted from and paid by the Sanitary District out of any moneys that may be due or may at any time thereafter become due to the said Contractor under and by virtue of this contract, as far as the same may suffice therefor. Should the amount remaining unpaid of the original contract price be insufficient to reim- burse the Sanitary District for fhe cost and expense of fully completing said work, then the Sanitary District may sell all materials, supplies, machinery, implements and tools ob- tained from the Contractor then on hand, at public sale on giving said Contractor twenty (20) days notice of the time and place of such 610 sale, and the net proceeds derived from the sale of said property at such sale shall be credited to said Contractor, and should the amount received from said sale be then insuffi- cient to pay such deficiency, the Contractor and his bondsmen shall be liable to pay the amount of said deficiency; and at any such sale of said property as provided hereunder, the Sanitary District may bid and become a purchaser of said property. It is further un- derstood and agreed that the terms and pro- visions of this Article 32 shall apply to and be binding upon any and all subcontractors of the original Contractor hereunder. Contractor’s Bond. Art. 33. The Contractor shall furnish a bond in the sum of fifty (50) per cent of the amount of this contract for the performance of the work under this contract, with good and suffi- cient sureties, the same to be satisfactory to the Board of Trustees of the Sanitary District, conditioned upon the faithful performance of all the terms and conditions of this contract; and should the sureties on said bond at any time fail financially, or be, in the opinion of the said Board of .Trustees, insufficient security for the penalty of said bond, then in that case the said Board of Trustees may, on giving ten (10) days notice thereof in writing, require said Contractor to furnish a new and addi- tional bond in place of the bond so having be- come insufficient, with such securities thereon as shall be satisfactory to the Board of Trus- tees of said Sanitary District. 611 Maintenance Bond.

The execution of said bond shall be a condition precedent to the final payment specified in Article 38. Electrical. The Contractor shall furnish a bond in the amount of five (5) per cent of the sum paid under Item 39 hereof, with a good and sufficient surety thereon, the same to be satisfactory to the Board of Trustees of the Sanitary District for the faithful fulfillment of the requirements of this contract that he will for one year subse- quent to the completion of the operating tests and acceptance of the switchboard, conduits and wiring and miscellaneous appurtenances and the furnishing and erection of miscellane- ous equipment, make good at his own expense any excessive wear to any parts, any defects in or damages to any parts and defects in or dam- ages to any equipment, appurtenances, wiring, or other material furnished or work done under this contract which may arise from faulty ma- terials, design, construction, installation or from the inability of any of the equipment, appurtenances, wiring or other material fur- nished or work done to successfully perform all the work put upon it within the limits of these specifications. The execution of said bond shall be a condition precedent to the final payment specified in Article 38. 613 Progress. Art. 35. The Contractor hereby agrees that the progress of the work under this contract shall be such that, on the respective dates shown in the following tabulation, the total amount of work completed (expressed in per- centage, in value, of the whole of said work) will be not less than that shown in said tabu- lation: TABULATION SHOWING TOTAL AMOUNT OF WORK TO BE COMPLETED ON DATES SHOWN: Per cent Date Completed July eee LOS Geen AAR ARS Fae ore 30 January.)
