CONTRACT DOCUMENTS.yfThe articles of agreement, the general conditions of the ebntract, the draw- ings with all notes thereon and the specifications are the documents forming the contract. 4. RELATION OF DOCUMENTS.— The above documents are co-operative, and what is called for by any one shall be as binding as if called for by two, three or all. Should they disagree, the better quality or greater quantity of work or materials shall be estimated upon and unless otherwise ordered in writing shall be furnished instead. 5. OMISSIONS FROM DOCUMENTS.— The omission from both drawings and specifications of express reference to any labor or materials reasonably to be inferred therefrom and necessary for the proper execution of the work, shall not relieve the Contractor from, furnishing them of a kind in keeping with the general character of the work. 6. SCHEDULE OF DATES.— The Contractor, if required, shall prepare in consultation with the Architects, a schedule assigning dates for the beginning of manufacture and installation of materials, and completion of the sundry parts of the work; and the latest dates at which the various detail drawings and decisions .will be required under proper conduct of the work. 7. DETAIL DRAWINGS.— Detail and working drawings, which shall be true developments of the scale drawings, will be furnished by the Architects from time to time, as necessary, and the work shall be executed in con- formity therewith. 8. ACCEPTANCE OF DETAIL DRAWINGS.— If detail drawings are, in the opinion of the Contractor, in- consistent with the scale drawings or the specifications, he shall notify the Architects before proceeding to execute the work therefrom, and in any case within ten days of their receipt, and failure so to do shall constitute a waiver of all claims for extra payment on such account. 9. FIGURES TO GOVERN.— Figured dimensions shall be followed in preference to measurements by scale; and larger scale drawings shall take precedence over those at smaller scale. 10. USE AND RETURN OF DRAWINGS AND MODELS. — The drawings and specifications furnished by the Architects shall be used for this work only. As instru- ments of service they are the property of the Architects and shall be returned to them. Any models furnished under this contract, or by the Owner, are his property and shall be dis- posed of as directed. 11. NUMBER OF COPIES FURNISHED.— The Architects will furnish to the Contractor, free of cost, one copy of each full size detail drawing, and two copies of all other drawings and of the specifications. 12. SHOP DRAWINGS AND MODELS.— The contractor shall furnish to the Architects at proper times all shop and setting drawings or diagrams which the Archi- tects may deem necessary to make clear the work intended and to show its relation to adjacent work of other trades. The Architects will inspect such drawings, but they shall not be held responsible for the Contractor's errors, the re- sults of which, should they occur, must be made good at the Contractor's expense. The Contractor shall make any re- quired changes in such drawings or diagrams and shall sup- ply two revised prints to the Architects, one to be returned to the Contractor, the other to be filed. Any samples, models, or templates submitted shall be changed as required until satisfactory. 13- DRAWINGS KEPT AT BUILDING.— A com- plete set of drawings and specifications wilt be kept in good and orderly condition at the work for the use of all con- nected therewith. Materials and Workmanship, and Their Inspection. 14. SKILLED WORKMEN.— No one unskilled in the work which he is given to do shall be employed, and all work shall be executed in a skillful and workmanlike man- ner. Should the Architects deem any one employed on the work incompetent or negligent, or for any cause unfit for his duties, and so certify, the Contractor shall dismiss him and he shall not again, without the permission of the Archi- tects, be employed on the work. 15. MATERIALS. — All materials, unless otherwise specified, shall be new and of the best quality of their respec- tive kinds. 16. INSPECTION.— The Contractor shall at all times maintain proper facilities and provide safe access for inspection to all parts of the work, and to the shops wherein the work is in preparation. No work shall be closed or cov- ered up until approved; should any work be covered up without having been approved, it must be uncovered, for ex- amination at the Contractor's expense, unless the Archi- tects have had timely notice of its readiness for inspection. 17. RE-EXAMINATION.— When required, the Contractor shall provide all facilities and labor necessary for a complete re-examination of work under suspicion, and if the work is found defective, the Contractor shall bear the expense of re-examination and replacement. If not found defective, the cost shall be credited to the Contractor as extra work. 18. CONDEMNATION,— The Contractor upon re- ceiving written notice from the Architects, and within such 5 reasonable time or times as may be named therein, shall re- move from the premises all materials condemned by him, whether worked or unworked, and take down all portions of the work which the Architects may by like written notice condemn as unsound or improper, or as in any way failing to conform to the contract, and he shall make good all work damaged or destroyed by the said removal, and he shall promptly re-execute the work in accordance with the con- tract and without expense to the Owner. 19. CLERK OF THE WORKS OR SUPERIN- TENDENT OF CONSTRUCTION.— If a Clerk of the Works or Superintendent of Construction be employed on behalf of the Owner he is not to be paid by the Contractor. He is to be selected by and act under the Architects who will prescribe his duties and define his authority. Financial Relations. 20. STATEMENT OF COSTS.— The Contractor shall, if required, before his application for first payment, furnish to the Architects, upon a blank form prepared by them, a correct statement, showing the cost of each part of the work as subdivided in the specifications, the total equal- ing the contract price. This statement shall be for the use of the Architects at their discretion, in preparing estimates for payments on account. 21. ISSUANCE OF CERTIFICATES.— At least ten days before each payment falls due the Contractor shall submit to the Architects a requisition therefor and shall, if required, submit therewith an itemized statement of the quantities and value of work performed to the termination of the period to be covered by the payment, and such state- ment shall be made in form provided or approved by the Architects ; but it shall not be binding as against their judg- ment. 22. PAYMENT OF FINAL CERTIFICATE A WAIVER. — The acceptance by the Contractor of the pay- ment of the final certificate shall constitute a waiver of all claims against the Owner under or arising out of this con- tract. 23. CERTIFICATES NOT FINAL EVIDENCE. — No certificate given, nor payment made under the con- tract, nor partial or entire occupancy of the building by the Owner shall be construed as an acceptance of defective work, or of improper materials, or as condoning any, omission, or as determining the date of completion. No payment nor certificate, final or otherwise, shall be construed as relieving the Contractor from his obligation to make good any defects discovered in his work after the completion and acceptance of the same, nor as a waiver of any specific obligation the Contractor may have assumed as to the durability of his work. 24. CERTIFICATES WITHHELD.— The Archi- tects may withhold any certificates, if, in their opinion, viola- tion of the contract exists after the Contractor has been duly notified to correct the same, and such certificates may be withheld until violations are corrected to the satisfaction of the Architects. 25. DEDUCTIONS FOR DEFECTIVE WORK— If, in the opinion of the Architects, it is not expedient to cor- rect injured work, or work not done in accordance with the contract, the Owner may deduct the difference in value be- tween the work involved and that called for by the contract, together with a fair allowance for damage, which sum shall be determined by the Architects, subject to Arbitration. 26. CHANGES IN WORK.— The Owner may, without invalidating the contract, make changes by altering, adding to or deducting from the work. No claim for an extra charge for such changes shall be valid unless such work is done in pursuance of a written order therefor from the Owner or from the Architects. All such work shall be executed under the conditions of the original contract, unless specifically provided to the contrary. 27. CONTRACTOR'S CLAIM FOR EXTRA RE- MUNERATION. — Should the Contractor deem any work which he is called upon to perform extra to the contract, he shall notify the Architects before proceeding to execute it, and in any case within five days of being called upon to per- form it, and failure so to do shall constitute a waiver of all claim for extra payment on account of it. If he shall so notify the Architects,- and if the Architects shall decide that no extra payment is due him on account of such work and shall order him to proceed therewith he must proceed, but he may appeal to arbitration as to the justness of such claim and the amount, if any, to be paid him in respect thereof. This article shall be held to confer upon the Contractor the right to appeal to arbitration in case of a decision adverse to a claim made by him under Article 8. 28. ADDITIONS AND DEDUCTIONS.— Should the Architects determine that any alterations, additions to or deductions from the work covered by the contract affect the contract price, then their value shall be determined in one or more of the three following ways, as may be selected by the Owner : A. By Unit Prices named in the contract or subse- quently agreed upon. In which case the Architects shall make the award, subject to Arbitration. B. By Cost and Percentage, in which case the Contrac- tor shall keep a true and correct account of the cost of labor and materials, rendering to the Arhitects, at required inter- vals, detailed statements and vouchers, and the Architects shall award an amount as cost and profit, subject to Arbitra- tion. C. By Estimate and Acceptance in a lump sum. In case an agreement as to price cannot be reached the Archi- tects may, with the authority of the Owner, order the work to proceed and the Contractor shall forthwith proceed and leave the price to be settled by Arbitration. 29. WAIVER OF LIENS.— Neither the Contractor nor any sub-contractor, materialman, nor any other person shall file or maintain a lien commonly called a mechanic's lien, for materials delivered for use in or work done in the performance of this contract ; and the right to maintain such lien by any or all of the above named parties is hereby ex- pressly waived, except in the event of the failure or refusal of the Owner to pay the amount called for by any certificate of the Architects, within sixty days of the date of its tender to the Owner for payment, then, and in such case only, shall the Contractor have the right to file and maintain a me- chanic's lien. 30. RELEASE OF LIENS.— Payments shall not be- come due unless at each payment the Contractor, if so re- quired, and in any event at the final payment, shall deliver to the Owner a satisfactory release of all liens against the premises on the part of all persons who have delivered ma- terials for use in, or done work in the performance of this contract, including a release from the Contractor himself. If at any time there shall be evidence of any lien or claim (except as permitted under Article 29), for which, if estab- lished, the Owner or the premises might be made liable, and which would be chargeable to the Contractor, the Owner shall have the right to retain out of any payment then due, or thereafter to become due, an amount sufficient to indemnify himself against such lien or claim until the same shall have been effectually discharged, or bonded. And should there prove to be any such claim after all payments are made, the Contractor shall refund to the Owner all moneys that the latter may be compelled to pay in discharging any lien upon said premises made obligatory in consequence of the Con- tractor's default. 31. CASH ALLOWANCES.— Where a provisional sum is mentioned in the agreement or specification, as a cash allowance for a certain purpose, the Contractor shall set aside such sum to be expended at the discretion of the Archi- tects, and the Contractor shall pay and expend it at such times and in such amounts and to and in favor of such per- sons as the Architects may in writing direct, and such allow- ance shall be for the actual cost of labor and material only, cost meaning the net cost to the Contractor, exclusive of office or other expenses, or profit, and such sums shall be payable by the Contractor without discount or deduction, or by the Owner directly if he so elect. All bills for labor and materials under such allowances shall be submitted to the Architects for their approval. Proper credit or debit shall be made in the contract price, according to the difference be- tween the cost of such material and labor, and the cash allow- ances named in the agreement or specification. The Con- tractor shall make sub-contracts with the parties furnishing such materials and labor, and he shall assume the same re- sponsibility for their work as for other portions of his work, but no such sub-contractor shall be employed upon the work against whom the Contractor shall make what the Archi- tects consider reasonable objection, or who will not enter into an agreement with the Contractor upon conditions con- sistent with those of this contract. 32. FIRE INSURANCE— The Contractor shall in- sure his work while in his charge against damage or destruc- tion by fire and for any loss of the Contractor from fire the Owner will not under any circumstances be accountable ; but when payments shall have been made, the Owner will assume the risk to the amount- of such payments. IO 33. CONTRACTOR'S LIABILITY FOR DELAY IN COMPLETION.— Should the Owner claim damages for delay in the completion of the work, the Architects, if, in their opinion, any damages be payable, shall make an award, and shall write the amount thereof across the face of the final certificate as "amount to be deducted from the face hereof for delay in completion of the work." Subject to Arbitration. Thereupon the Architects' services in this matter shall terminate, except as provided under Art. 40. 34. CONTRACTOR'S CLAIM FOR EXTEN- SION OF TIME.— Should the Contractor be delayed in the prosecution or completion of the work by authorized additions thereto, by the act, neglect or default of the Own- er, of anyone employed by the Owner, or by any damage caused by fire or other casualty for which the Contractor is not responsible, or by general strikes, then the time fixed in the Agreement for the completion of the work shall be ex- tended for a period equivalent to the time lost by reason of any or all the causes aforesaid, which extended period shall be determined and fixed by the Architects, subject to Arbi- tration, but no such allowance shall be made unless a claim therefor is presented in writing to the Architects within forty-eight hours of the occurrence of such delay. 35. CONTRACTOR'S CLAIM FOR DAMAGES. — Should the Contractor be damaged by the act, neglect or default of the Owner or of the Architects, then the amount of said damage shall be determined and awarded by the Architects, subject to Arbitration, but no such allowance shall be made unless a claim therefor is presented in writing to the Architects within forty-eight hours of the occurrence of such damage. 36. MUTUAL RESPONSIBILITY OF CON- TRACTORS. — Should the Contractor be damaged by the act, neglect or default of any other contractor employed by II the Owner upon the work, then the Contractor shall make his claim directly upon such other contractor, the several contractors being mutually responsible and the Owner being in no way responsible to any of them for the acts, neglect or default of any other. 37. CONTRACTOR'S RESPONSIBILITY FOR DAMAGES. — The Contractor shall be responsible for and make good, to the satisfaction of the Architects, all dam- ages, except by fire, arising directly or indirectly from opera- tions under his contract, to the adjoining streets, to side walks or premises, or to the property of any person in or about the building or upon the ways adjacent thereto (ex- cept as covered in Article 36), for which alleged damages claim shall have been made against the Owner. 38. COMPENSATION FOR PROTRACTED SER- VICES. — Should the Contractor by his own fault or neg- ligence delay the completion of the work, thereby necessitat- ing unusual or protracted services on the part of the Archi- tects or the Clerk of the Works, or Superintendent of Con- struction, the Owner shall be entitled to retain from the amount otherwise to become due to the Contractor, an amount sufficient properly to reimburse any or all of them for such protracted or unusual services, subject to Arbitra- tion. 39. CASES SUBJECT TO ARBITRATION.— The final decision of all questions arising under this contract shall be made and given by the architects and both the Own- er and the Contractor shall be bound, and will abide by such decision, save only in the following cases, which may be arbitrated in the manner provided in Article 40 : A. Deductions for Defective Work, Art. 25. B. Contractor's claim for extra remuneration, Art. 27. C. Additions and Deductions, Art. 28. 12 D. Contractor's Liability for Delay in Completion, Art. 33. E. Contractor's Claim for Extension of Time, Art. 34. F. Contractor's Claim for Damages, Art. 35. G. Compensation for Protracted Services, Art. 38. 40. METHOD OF ARBITRATION.— In any of the above named cases the Owner or the Contractor may de- mand arbitration, by filing with the Architects within ten days of the receipt of the decision or claim from which he appeals, a written notice of such demand, sending at the same time a copy thereof to the other party to the contract, and within ten days of receipt of such notice the case shall be submitted to three disinterested arbitrators, one chosen by the Owner, one by the Contractor, and the third chosen by these two arbitrators. The Arbitrators shall act with promptness and the decision of any two of them shall be final and binding on both parties hereto. The Arbitrators shall assess the costs and charges of the arbitration upon the Owner or the Contractor, or upon both, in such propor- tions as they, the Arbitrators, shall deem just. Status and Duties of the Architects. 41. STATUS OF THE ARCHITECTS.— The Architects are the judicial interpreters of the contract docu- ments, and in that capacity they are to define their true in- tent and meaning. They are the counsel and not the agent of the Owner except in structural emergencies (Article 44) and except when in special instances they be authorized by the Owner so to act. 42. DUTIES OF THE ARCHITECTS.— The Architects will furnish all necessary drawings and specifica- tions, except as noted in Art. 12. As supervisors of the work they will explain and supplement the drawings and specifications, and will decide whether the work and ma- terials are in conformity with the contract. They will keep *3 accounts, verify estimates of work done and issue certifi- cates when payments are due. They will compute or check all deductions from and additions to the contract price, and determine the responsibility of the Contrator or Owner for failure to fulfill the terms of the contract, and will perform such other services as may be herein set forth. 43. LIMITATION OF DUTIES OF ARCHI- TECTS. — The Architects will notify the Contractor of the rejection of faulty work as it comes to their attention, but their failure to detect violations of the contract shall not act as an acceptance of the work. It is not incumbent upon the Architects to notify the Contrator when to begin, cease, or resume work. 44. AUTHORITY OF THE ARCHITECTS.— The Architects have authority to stop the progress of the work whenever, in their opinion, such stoppage may be nec- essary to insure the proper execution of the contract. They have authority to condemn and order the removal of any materials, whether worked or unworked, or any portions of the work, which in their opinion are not in accordance with the contract, In an emergency affecting the safety of the structure, they have authority to make such changes or to order such work, extra to the contract or otherwise, as may in their opinion be necessary. The Owner's Duties and Rights. 45. WORK NOT IN CONTRACT.— The Owner reserves the right to let contracts other than this one in con- nection with this work, and he shall provide all labor and materials, not included in this contract, essential to the con- duct of this work, in such manner as not to delay its pro- gress. 14 46. OWNER'S RIGHT TO DO WORK IN CON- TRACTOR'S DEFAULT.— Should the Contractor become insolvent, or at any time refuse or neglect to supply a suf- ficiency of properly skilled workmen or of materials of the proper quality, or fail in any respect to prosecute the work with promptness and diligence, or fail in the performance of any of the agreements herein contained, such refusal, ne- glect or failure being certified by the Architects the Owner shall be at liberty, after forty-eight hours' written notice, served personally upon the Contractor, or delivered at his last known address, to provide any such labor or materials, and to deduct the cost thereof from any money then due or thereafter to become due to the Contractor under the Con- tract. 47. OWNER'S RIGHT TO' TERMINATE CON- TRACT. — If the Architects shall certify'that such refusal, neglect or failure, as described in Art. 46, is sufficient ground for such action, the Owner shall also be at liberty to terminate the employment of the Contractor for said work, and for the purpose of completing the work, enter upon the premises and take possession thereof, and of all materials, tools and appliances thereon, and to employ any other per- son or persons to finish the work, and to provide the ma- terials therefor; and in case of such discontinuance of the employment of the Contractor, he shall not be entitled to re- ceive any further payment until the said work shall be wholly finished, at which time, if the unpaid balance of the amount to be paid shall exceed the expense incurred by the Owner in finishing the work, including proper compensation to the Architects for their additional services in connection there- with, such excess shall be paid by the Owner to the Contrac- tor; but if such expense shall exceed such unpaid balance, the Contractor shall pay the difference to the Owner. The expense incurred by the Owner as herein provided, either for furnishing materials or for finishing the work, and any damage incurred through such default, shall be audited and certified by the Architects. 15 Contractor's Duties and Rights. 48.

COMPETENT FOREMAN.— The Contractor shall give personal superintendence to the work and shall keep a competent general foreman, satisfactory to the Archi- tects, constantly on the work, who shall remain in charge from the beginning to the completion of the work, unless changed with the consent or at the instance of the Archi- tects. He shall represent the Contractor in his absence, and all directions given to him shall be as binding as if given to the Contractor; and if, in the judgment of the Architects, i6 assistants to the foreman are needed, the Contractor shall provide them. 54.

VERIFICATION OF DRAWINGS, ETC.— The Contractor, as a part of his services, shall carefully study and compare all drawings, specifications and other in- formation given to him by the Architects, both as to figures, materials and methods of construction, using therein the skill and experience for which he receives compensation un- der this contract, and shall immediately report to the Archi- tects for rectification any error, inconsistency or omission therein, which he shall discover. 56. MEASUREMENTS.— The Contractor shall measure work already in place, to insure the proper execu- tion of subsequent work, or for the information of the Architects, and should any discrepancy between the executed work and the drawings be discovered, he shall report it at once to the Architects. 57.

REPORTS.— The Contractor shall furnish, whenever required, and in the manner directed, reports showing the progress and status of the work at the building, and in the shops. 59. VOUCHERS AND SAMPLES.— The Contrac- tor shall, when required, produce vouchers showing the kind and quality of materials used, and furnish duplicate labeled samples of materials and workmanship, with sufficient in- formation, for the approval of the Architects, and the ma- terials and workmanship furnished shall be equal to the ap- proved samples. 60. PATENTS, FEES.— The Contractor shall pay all royalties and license fees, and shall save the Owner harmless from loss or annoyance on account of suits or claims of any kind for infringement of patents in connection with his work. 61. RUBBISH.— The Contractor shall not allow waste material or rubbish caused by his own mechanics to accumulate in or about the premises, but shall promptly re- move the same and at the completion of the work he shall thoroughly remove all his rubbish from and about the build- ing, and all tools, scaffolding and surplus materials, and shall leave his work thoroughly cleaned and ready for use. In case of dispute the Owner will remove the rubbish and charge the cost of work to the Contractors pro rata, 62.

DAMAGE TO PERSONS.— The Contractor shall be solely answerable for all damages or injury caused to any or all persons whether employed upon or about the work or not, or to the public, by himself or those working under him or through any operations under his charge, whether covered by the original contract, or otherwise, and agrees to protect the Owner from every claim, demand or suit on said account, and to indemnify him for every verdict recovered against him on account of such damage or injury. 68. ACCIDENT INSURANCE.— The Contractor shall take out and maintain adequate accident insurance for any and every person, whether employed by the Contractor or not, who may sustain bodily injury in or upon or about the building or upon the ways adjacent thereto, and arising directly or indirectly from operations under this contract, 19 and he shall be responsible for failure to maintain such in- surance. 69. LOADING.— The Contractor shall not permit anyone directly or indirectly in his employ to load any part of the structure with a weight greater than it is calculated to bear. 70. NOTICE OF IMPERFECT WORK OR MA- TERIAL. — Where the Contractor's work is associated with that of another trade, he shall examine the adjacent work and report in writing to the Architects any defect or condi- tion preventing the proper execution of his contract, and in case he shall proceed without giving such notice, the Con- tractor shall be held to have accepted such work or material, and the existing conditions, and shall be responsible for any defects in his own work consequent thereon, and shall not be relieved of the obligation of any guarantee because of any such condition or imperfection. 71.

CLEARING OF THE SITE.— This will be done by the Owner. Three of the buildings now standing will have been removed by July 1st, 1909, and the fourth (Guyot House) by August 1st, 1909. 74. WATCHMAN. — During such time as the Owner and Architects deem wise or necessary, a watchman will be provided at the expense of the Owner. Though this will be an advantage and saving to the various contractors, neither the Owner or anyone will be responsible at any time for anything that may occur through lack of a watchman or the negligence or any fault of such watchman. Any contractor may supply his own watchman for such length of time as he deems necessary subject to the approval of the Architects, if he deems the above provisions insufficient for his interests. 75. CO-OPERATION.— Each contractor shall co- operate with the other contractors and work in conjunction with them to obtain expedition and the best results in all ways.

It must conform to the following requirements and pass the test herein specified: Manufacturers to guarantee that all ce- ment has been seasoned or subject to aeration at least thirty (•30) days before leaving the works. Cement may be in barrels or bags, and if in bags, four bags shall in all cases be considered as one barrel. TESTING. — Tests shall be made by chemists named by the Architects, and paid by the Contractors, upon the approval of the bills by the Architects. The following allowances shall be made and shall be paid for all cement tested, whether accepted or rejected: Eleven cents per barrel for all lots of 150 barrels (600 bags) or more, and thirteen cents per barrel for all lots of 100 bar- rels (400 bags) or less. For lots between 100 and 150 barrels the cost shall be the same as for 1 50 barrels.
