It is not intended, however, that the Con- tractor shall supply products or perform work not consistent with, covered by or properly inferable from the Contract Documents. 1.4 Words and abbreviations which have well known technical or trade meanings are used in the Contract Documents in accordance with such recognized meanings. 1.5 References to the masculine or the singular shall be considered to include the feminine and the plural as the context requires. 1.6 1.7 1.8 1.9 1.10 In the event of conflicts between Contract Documents the following shall apply: (a) figured dimensions shown on a drawing shall govern even though they may differ from dimensions scaled on the same drawing, (b) drawings of larger scale shall govern over those of smaller scale of the same date, (c) specifications shall govern over drawings, (d) the General Conditions shall govern over specifications, (e) Supplementary Conditions shall govern over the General Conditions, and (f) the executed Agreement between the Owner and Contractor shall govern over all documents. Notwithstanding the foregoing, documents of later date shall always govern. Th"e Contractor shall be provided without charge with as many copies of the Contract Documents or parts thereof as are necessary for the performance of the Work. The Contractor shall keep one copy of current Contract Documents and shop drawings at the Place of the Work, in good order and available to the Consultant and his representatives. This requirement shall not be considered to include the executed set of Contract Documents.

The Consultant will be the Owner's representative during construction and until completion of any correction of defects under the provisions of GC 24 - WARRANTY, paragraph 24.2, or until the issuance of the Certificate of Total Performance of the Work, whichever is later. The Owner's instructions to the Contractor shall be forwarded through the Consultant. The Consultant will have authority to act on behalf of the Owner only to the extent provided in the Contract Documents, unless otherwise modified by written agreement in accordance with paragraph 3.13. The Consultant will not be responsible for and will not have control or charge of construction means, methods, techniques, sequences or procedures, or for safety precautions and programs required for the Work in accordance with the applicable construction safety legislation, other regulations or general con- struction practice. The Consultant will not be responsible for or have control or charge over the acts or omissions of the Contractor, his Subcontractors, or their agents, employees or other .persons performing allY of the Work. The Consultant will visit the site at intervals appropriate to the progress of construction to familiarize himself with the progress and quality of the Work and to record the data necessary to establish the pay quantities under the Schedule of Contract Unit Prices. Based on the Consultant's observations and his evaluation of the Contractor's applications for payment, the Consultant will determine the amounts owing to the Contractor under the Contract and will issue cer- tificates for payment in such amounts, as provided in Article A-4 - PAYMENT and GC 14 - CER- TIFICATES AND PAYMENTS. The Consultant will be, in the first instance, the interpreter of the requirements of the Contract Documents and the judge of the performance thereunder by both parties to the Contract.

Claims, disputes and other matters in question relating to the performance of the Work or the interpretation of the Contract Documents shall be referred initially to the Consultant in writing for decision which he will give in writing within a reasonable time. The Consultant will have authority to reject work which in his opinion does not conform to the requirements of the Contract Documents. Whenever he considers it necessary or advisable he will have authority to require special inspection or testing of work whether or not such work be then fabricated, in- stalled or completed. However, neither the Consultant's authority to act nor any decision made by him either to exercise or not to exercise such authority shall give rise to any duty or responsibility of the Consul- tant to the Contractor, his Subcontractors, or their agents, employees or other persons performing any of the Work. The Consultant will review and take appropriate action upon the Contractor's submittals such as shop drawings, product data, and samples, in accordance with the requirements of the Contract Documents.

If the Owner and the Consultant agree, the Consultant will provide at the site one or more project representatives to assist the Consultant in carrying out his responsibilities. The duties, responsibilities and limitations of authority of such project representatives shall be as set forth in writing to the Contractor but shall in any event provide for the timely recording of the data necessary to establish the pay quantities under the Schedule of Contract Unit Prices. The duties, responsibilities and limitations of authority of the Consultant as set forth in the Contract Documents will not be modified or extended without the written consent of the Owner, the Contractor and the Consultant.

DELAYS If the Contractor is delayed in the performance of the Work by an act or omission of the Owner, Consultant, Other Contractor, or anyone employed or engaged by them directly or indirectly, contrary to the provisions of the Contract Documents, then the Contract Time shall be extended for such reasonable time as the Consultant may decide in consultation with the Contractor. The Contractor shall be reimbursed by the Owner for reasonable costs incurred by the Contractor as the result of such delay. If the Contractor is delayed in the performance of the Work by a stop work order issued by a court or other public authority and providing that such order was not issued as the result of an act or fault of the Contrac- tor or anyone employed or engaged by him directly or indirectly, then the Contract Time shall be extended for such reasonable time as the Consultant may decide in consultation with the Contractor. The Contrac- tor shall be reimbursed by the Owner for reasonable costs incurred by the Contractor as the result of such delay. If the Contractor is delayed in the performance of the Work by labour disputes, strikes, lock-outs (including lock-outs decreed or recommended for its members by a recognized contractors' association, of which the Contractor is a member or to which the Contractor is otherwise bound), fire, unusual delay by common carriers or unavoidable casualties or, without limit to any of the foregoing, by a cause beyond the Contractor's control, then the Contract Time shall be extended for such reasonable time as the Consultant may decide in consultation with the Contractor, but in no case shall the extension of time be less than the time lost as the result of the event causing the delay, unless such shorter extension be agreed to by the Contractor. The Contractor shall not be entitled to payment for costs incurred as the result of such delays unless such delays are as the result of actions by the Owner. No extension shall be made for delay unless written notice of claim is given to the Consultant not later than fourteen (14) days after the commencement of delay, providing however, that in the case of a continuing cause of delay only one notice of claim shall be necessary. If no schedule is made under GC 2 - ADDITIONAL INSTRUCTIONS, no claim for delay shall be allowed because of failure to furnish instructions until fourteen (14) days after a demand for such instructions has been made and not then unless such claim is reasonable. The Consultant will not, except by written notice to the Contractor, stop or delay the Work pending instructions or proposed changes in the Work. OWNER'S RIGHT TO PERFORM WORK OR STOP THE WORK OR TERMINATE CONTRACT If the Contractor should be adjudged bankrupt, or makes a general assignment for the benefit of creditors because of his insolvency or if a receiver is appointed because of his insolvency, the Owner may, without prejudice to any other right or remedy he may have, by giving the Contractor or receiver or trustee in bankruptcy written notice, terminate the Contract. If the Contractor should neglect to prosecute the Work properly or otherwise fails to comply with the requirements of the Contract to a substantial degree and if the Consultant has given a written statement to the Owner and Contractor that sufficient cause exists, the Owner may notify the Contractor in writing that he is in default of his contractual obligations and instruct him to correct the default in the five (5) working days immediately following the receipt of such notice. If the correction of the default cannot be completed in the five (5) working days specified, the Contractor shall be in compliance with the Owner's instructions if he: (al commences the correction of the default within the specified time, and (b) provides the Owner with an acceptable schedule for such correction, and (c) completes the correction in accordance with such schedule. If the Contractor fails to correct the default in the time specified or subsequently agreed upon, the Owner, without prejudice to any other right or remedy he may have, may: (a) correct such default and deduct the cost thereof from any payment then or thereafter due the Con- tractor provided the Consultant has certified such cost to the Owner and the Contractor, or (b) terminate the Contractor's right to continue with the Work in whole or in part or terminate the Contract. ceDe 4 - 1982 File 00720 13 5.5 5.6 5.7 GC 6 6.1 6.2 GC 7 . 7.1 If the Owner terminates the Contractor's right to continue with the Work under the conditions set out in this General Condition, he shall: (a) be entitled to take possession of the premises and products and utilize the construction machinery and equipment the whole subject to the rights of third parties, and finish the Work by whatever method he may consider expedient but without undue delay or expense, and (b) withhold further payments to the Contractor until the Work is finished, and (c) upon Total Performance of the Work, charge the Contractor the amount by which the full cost of finishing the Work as certified by the Consultant, including compensation to the Consultant for his additional services and a reasonable allowance as determined by the Consultant to cover the cost of corrections to work performed by the Contractor that may be required under GC 24 - WARRANTY, exceeds the unpaid balance of the Contract Price; however, if such cost of finishing the Work is less than the unpaid balance of the Contract Price, he shall pay the Contractor the difference, and (d) on expiry of the warranty period, charge the Contractor the amount by which the cost of corrections to his work under GC 24 - WARRANTY exceeds the allowance provided for such corrections, or if the cost of such corrections is less than the alloiNance, pay the Contractor the difference. If a performance bond has been provided by the Contractor the provisions of this General Condition shall be exercised in accordance with the conditions of such performance bond. The Contractor's obligation under the Contract as to quality, correction and warranty of the work performed by him up to the time of termination shall continue in force after such termination. I I I I I I I 6.3 CONTRACTOR'S RIGHT TO STOP THE WORK OR TERMINATE CONTRACT If the Owner should be adjudged bankrupt or makes a general assignment for the benefit of creditors because of his insolvency or if a receiver is appointed because of his insolvency, the Contractor may, without prejudice to any other right or remedy he may have, by giving the Owner or receiver or trustee in bankr'uptcy written notice, terminate the Contract. If the Work should be stopped or otherwise delayed for a period of thirty (30) days or more under an order of a court or other public authority and providing that such order was not issued as the result of an act or fault of the Contractor or of anyone directly or indirectly employed or engaged by him, the Contractor may, without prejudice to any other right. or remedy he may have, by giving the Owner written notice, terminate the Contract. The Contractor may notify the Owner in writing, with a copy to the Consultant, that the Owner is in default of his contractual obligations if: (a) the Consultant fails to issue a certificate in accordance with the provisions of GC 14 - CER- TIFICA TES AND PA YMENTS, or (b) the Owner fails to pay the Contractor when due the amounts certified by the Consultant or awarded by arbitration or court, or (c) the Owner violates the requirements of the Contract to a substantial degree and the Consultant con- firms by written statement to the Contractor that sufficient cause exists. The Contractor's written notice to the Owner shall advise that if the default is not corrected in the five (5) working days immediately following the receipt of the written notice the Contractor may, without pre- judice to any other right or remedy he may have, stop the Work or terminate the Contract. If the Contractor terminates the Contract under the conditions set out above, he shall be entitled to be paid for all work performed in accordance with the Schedule of Contract Unit Prices and for loss sustained upon products and construction machinery and equipment and such other damages as the Contractor may have sustained as a result of the termination of the Contract. I I I I I I I 6.4 I I DISPUTES I Differences between the parties to the Contract as to the interpretation, application or administration of this Contract or any failure to agree where agreement between the parties is called for, herein collectively called disputes, which are not resolved in the first instance by decision of the Consultant pursuant to the provisions of GC 3 - CONSULTANT, paragraphs 3.6 and 3.7, shall be settled in accordance with the re- quirements of this General Condition. I 14 eeDe 4 - 1982 File 00720 I I I I I I I I I I I I I I I I I I I I OTHER CONTRACTORS The Owner reserves the right to let separate contracts in connection with the Project of which the Work is a part, or do certain work by his own forces. When separate contracts are awarded for different parts of the Project, or work is performed by the Owner's own forces, the Owner shall: (a) provide for the co-ordination of the work of his own forces and of each separate contract with the Work of this Contract, and (b) ensure that insurance coverage is provided to the same requirements as are called for in GC 20 -INSURANCE. Such insurance shall be co-ordinated with the insurance coverage of this Contractor as it affects the Work of this Contract. The Contractor shall co-ordinate the Work of this Contract with the work of Other Contractors and connect as specified or shown in the Contract Documents. If there is a change in the scope of the work re- quired for the planning and performance of this co-ordination and connection, the changes shall be authorized in accordance with GC 11 - CHANGES IN THE WORK AND EXTRA WORK, and the value of the changes shall be determined in accordance with GC 12 - VALUATION AND CERTIFICATION OF CHANGES IN THE WORK. 9.4 The Contractor shall report to the Consultant any apparent deficiencies in Other Contractors' work which would affect the Work of this Contract immediately they come to his attention and shall confirm such report in writing. Failure by the Contractor to so report shall invalidate any claims against the Owner by reason of the deficiencies of Other Contractors' work except as to those of which he was not reasonably aware. 7.4 7.5 7.6 7.7 GC 8 8.1 GC 9 9.1 9.2 9.3 The claimant shall give written notice of such dispute to the other party no later than thirty (30) days after the receipt of the Consultant's decision given under GC 3 - CONSULTANT, paragraph 3.7. Such notice shall set forth particulars of the matters in dispute, the probable extent and value of the damage and the relevant provisions of the Contract Documents. The other party shall reply to such notice no later than fourteen (14) days after he receives or is considered to have received it, setting out in such reply his grounds and other relevant provisions of the Contract Documents. If the matter in dispute is not resolved promptly the Consultant will give such instructions as in his opinion are necessary for the proper performance of the Work and to prevent delays pending settlement of the dispute. The parties shall act immediately according to such instructions, it being understood that by so doing neither party will jeopardize any claim they may have. If'it is subsequently determined that such instructions were in error or at variance with the Contract Documents, the Owner shall pay the Contractor costs incurred by the Contractor in carrying out such instructions which he was required to do beyond what the Contract Documents correctly understood and interpreted would have required him to do, including costs resulting from interruption of the Work. .. It is agreed that no act by either party shall be construed as a renunciation or waiver of any of his rights or recourses, provided he has given the notices in accordance with paragraph 7.2 and has carried out the instructions as provided in paragraph 7.3. If the parties have agreed to submit disputes to arbitration pursuant to a Supplementary Condition to the Contract, or by subsequent agreement, then the dispute shall be submitted to arbitration in accordance with the provisions of the arbitration legislation of the Place of the Work. If no provision or agreement is made for arbitration then either party may submit the dispute to such judicial tribunal as the circumstances may require. In recognition of the obligation by the Contractor to perform the disputed work as provided in paragraph 7.3, it is agreed that settlement of dispute proceedings may be commenced immediately following the dispute in accordance with the aforegoing settlement of dispute procedures. ASSIGNMENT Neither party to the Contract shall assign the Contract or a portion thereof without the written consent of the other, which consent shall not be unreasonably withheld. 9.5 The Owner shall take all reasonable precautions to avoid labour disputes or other disputes on the Project arising from the work of Other Contractors. CCDC4 - 1982 File 00720 15 GC10 SUBCONTRACTORS 10. 1 The Contractor agrees to preserve and protect the rights of the parties under the Contract with respect to work to be performed under subcontract and to: (a) enter into contracts or written agreements with his Subcontractors to require them to perform their work in accordance with and subject to the terms and conditions of the Contract Documents, and (b) be as fully responsible to the Owner for acts and omissions of his Subcontractors and of persons directly or indirectly employed by them as for acts and omissions of persons directly employed by him. The Contractor therefore agrees that he will incorporate' the terms and conditions of the Contract Documents into all subcontract agreements he enters into with his Subcontractors. 10.2 The Contractor agrees to employ those Subcontractors proposed by him in writing and accepted by the Owner at the signing of the Contract. 10.3 The Owner may, for reasonable cause, object to the use of a proposed Subcontractor and require the Contractor to employ one of the other subcontract bidders. 10.4 In the event that the Owner requires a change from a proposed Subcontractor the Contract Price shall be adjusted by the difference in cost and mark-up occasioned by such required change. 10.5 The Contractor shall not be required to employ as a Subcontractor a person or firm to whom he may reasonably object. 10.6 The Consultant may, upon reasonable request and at his discretion, provide to a Subcontractor information as to the percentage or quantity of the Subcontractor's work which has been certified for payment. 10.7 Nothing contained in the Contract Documents shall create a contractual relationship between a Subcontractor and the Owner. GC11 11.1 11.2 GC12 12.1 12.2 16 CHANGES IN THE WORK AND EXTRA WORK Changes in the Work: Except as provided in GC 12 - VALUATION AND CERTIFICATION OF CHANGES IN THE WORK, paragraph 12.4: (a) the Owner, through the Consultant, without invalidating the Contract, may make Changes in the Work with the Contract Price and Contract Time being adjusted accordingly by written order, and (b) no Changes in the Work shall be proceeded with without a written order signed by the Owner and no claim for a change in the Contract Price or change in the Contract Time shall be valid unless so . ordered and at the same time valued or agreed to be valued as provided in GC 12 - VALUATION AND CERTIFICATION OF CHANGES IN THE WORK. Extra Work: (a) The Owner may offer the Contractor Extra Work. If the terms and conditions for the performance of the Extra Work are agreed upon, the Owner, through the Consultant, shall issue a written change order amending the Contract Price and Contract Time as appropriate, or a written order to proceed until a price and change in time are agreed upon by the parties and a change order can be issued. VALUATION AND CERTIFICATION OF CHANGES IN THE WORK If the type of work involved in a Change in the Work is included in the items contained in the Schedule of Contract Unit Prices in Article A-3 - CONTRACT PRICE, paragraph (c), it shall be performed on the same payment basis as the original Work except as described in paragraphs 12.7 and 12.8, and the Contract Time shall be extended for such time as the Consultant may decide in consultation with the Contractor. If the type of work involved in a Change in the Work is not included in the items contained in the Schedule of Contract Unit Prices in Article A-3 - CONTRACT PRICE, paragraph (c), or is such as to alter the nature or intent of the work included in this Schedule, the value of such change shall be determined in one or more of the following methods: (a) by estimate and acceptance in a lump sum; (b) by unit prices agreed upon; (c) by cost and a fixed or percentage fee; (d) by variation of the Contract Unit Prices. CCDC4-1982FileOO12O I I I I I I I I I I I I I I I I I I I I 12.3 I I 12.4 I 12.5 I I 12.6 I 12.7 I I 12.8 I 12.9 I I 12.10 I GC13 13.1 13.2 I 13.3 I 13.4 I When a Change in the Work covered by paragraph 12.2 is proposed or required the Contractor shall present to the Consultant for approval his claim for a change in the Contract Price and change in Contract Time with appropriate documentation in a form acceptable to the Consultant. The Consultant will satisfy himself as to the correctness of such claim and, when approved by the Owner, a change order shall be issued to the Contractor amending the Contract Price and Contract Time as appropriate. The value of work performed in the change shall be included for payment with the regular certificates for payment. In the case of Changes in the Work to be paid for under methods (b) and (c) of paragraph 12.2, the form of presentation of costs and methods of measurement shall be agreed to by the Consultant and Contractor before proceeding with the change. The Contractor shall keep accurate records, as agreed upon, of quantities or costs and present an account of the cost of the Change in the Work, together with vouchers where applicable. If the method of valuation, measurement, change in Contract Price and change in Contract Time cannot be promptly agreed upon, and the change is required to be proceeded with then the Consultant in the first instance will determine the method of valuation, measurement and the change fn Contract Price and Contract Time subject to final determination in the manner set out in GC 7 - DISPUTES. In this case the Consultant will, with the consent of the Owner, issue a written authorization for the change setting out the method of valuation and if by lump sum his valuation of the change in Contract Price and Contract Time. In the case of a dispute in the valuation of a change authorized in the Work and pending final determination of such value, the Consultant will certify the value of work performed in accordance with his own evaluation of the change and include the amount with the regular certificates for payment. The Contractor shall keep accurate records of quantities and cost of such work. Should the actual quantity of an item in the Schedule of Contract Unit Prices referred to in Article A-3 _ CONTRACT PRICE, paragraph (c), vary by more than 15% of the estimated quantity, either the Owner or the Contractor may request a revision to the Contract Unit Price contained in the Schedule. Such a re- quest for a revision in a Contract Unit Price shall be given as soon as reasonably possible after the party concerned becomes aware of the circumstances. If a revision to a Contract Unit Price is negotiated, then: (a) the revised unit price in the case of a decrease of more than 15% of the estimated quantity will apply to the actual work performed for that item, and (b) the revised unit price in the case of an increase of more than 15% of the estimated quantity will apply to the excess quantity of work for that item only. If either party requests renegotiation of a Contract Unit Price, both parties agree to act promptly in order to arrive at an equitable revision of the Contract Unit Price prior to proceeding with the work so affected. If agreement of such renegotiation cannot be reached, the Contractor shall proceed with the work and the matter shall be subject to final determination in the manner set out in GC 7 - DISPUTES. Pending such settlement, payment for the work performed shall be made on the regular certificates for payment on the basis of the Contract Unit Prices. It is intended in all matters referred to above that the Owner, the Consultant and Contractor shall act promptly. APPLICATIONS FOR PAYMENT Applications for payment on account may be made monthly as the Work progresses. Applications for payment shall be dated the last day of the agreed monthly payment period and the amount claimed shall be for the value of work performed and products delivered to the Place of the Work at that date. Applications for payment for products delivered to the Place of the Work but not yet incorporated into the Work shall be supported by such evidence as the Consultant may reasonably require to establish the value and delivery of the products. Applications for release of holdback monies following Substantial Performance of the Work and the application for final payment shall be made at the time and in the manner set forth in GC 14 _ CERTIFICATES AND PAYMENTS. GC 14 CERTIFICATES AND PAYMENTS 14.1 The Consultant will, no later than ten (10) days after the receipt of an application for payment from the Contractor submitted in accordance with GC 13 - APPLICATIONS FOR PAYMENT, issue a certificate for payment in the amount applied for or in such other amount as he determines to be properly due. If the Consultant amends the application, he will promptly notify the Contractor in writing giving his reasons for the amendment. I I I eeDe 4 - 1982 File 00720 17 14.2 The Owner shall make payment to the Contractor on account in accordance with the provisions of Article A-4 - PAYMENT no later than fifteen (15) days after the issuance of a certificate for payment by the Con- su/tant. 14.3 The Consultant will, no later than ten (10) days after the receipt of an application from the Contractor for a certificate of Substantial Performance of the Work, make an inspection and assessment of the Work to verify the validity of the application. The Consultant will, no later than seven (7) days after his inspection, notify the Contractor of his approval or the reasons for his disapproval of the application. When the Con- sultant finds that Substantial Performance of the Work has been reached he will issue such a certificate. The date of Substantial Performance of the Work shall be as stated in this certificate. Immediately follow- ing the issuance of the certificate of Substantial Performance of the Work, the Consultant, in consultation with the Contractor, will establish a reasonable date for the Total Performance of the Work. 14.4 Immediately following the issuance of the certificate of Substantial Performance of the Work the Consultant will issue a certificate for payment of holdback monies. The holdback monies authorized by this certificate shall become due and payable on the day following the expiration of the statutory limitation period stipulated in the lien legislation applicable to the Place of the Work or where such legislation does not exist or apply in accordance with such other legislation, industry practice or such other provisions which may be agreed to between the parties, providing that the Owner may retain out of such holdback monies any sums required by law to satisfy any liens against the Work or other monetary claims against the Contractor and enforceable against the Owner and that the Contractor has submitted to the Owner a sworn statement that all accounts for labour, subcontracts, products, construction machinery and equip- ment and other indebtedness which may have been incurred by the Contractor in the Substantial Performance of the Work and for which the Owner might in any way be held responsible have been paid in full except holdback monies properly retained. 14.5 Where legislation permits and where, upon application by the Contractor, the Consultant has certified that the work of a Subcontractor has been totally performed to his satisfaction prior to the Substantial Per- formance of the Work, the Owner shall pay the Contractor the holdback retained for such Subcontractor on the day following the expiration of the statutory limitation period for such Subcontractor stipulated in the lien legislation applicable to the Place of the Work. 14.6 Notwithstanding the provisions of paragraph 14.5 and notwithstanding the wording of such certificates the Contractor shall ensure that such work is protected pending the Total Performance of the Work and be responsible for the correction of defects in it regardless of whether or not they were apparent when such certificates were issued. " 14.7 The Consultant will, no later than ten (10) days after the receipt of an application from the Contractor for payment upon Total Performance of the Work, make an inspection and assessment of the Work to verify the validity of the application. The Consultant will, no later than seven (7) days after his inspection, notify the Contractor of his approval or the reasons for his disapproval of the application. When the Consultant finds that Total Performance of the Work has been reached he will issue a certificate of Total Performance of the Work and certify for payment the remaining monies due to the Contractor under the Contract less holdback monies which are required to be retained. The date of Total Performance of the Work shall be as stated in this certificate. Subject to the provisions of GC 18 - WORKERS' COMPENSATION INSURANCE, paragraph 18.1 the Owner shall, no later than fifteen (15) days after the issuance of such certificate, make payment to the Contractor in accordance with the provisions of Article A-4 - PAY- MENT. 14.8 The release of the remaining holdback monies shall become due and payable on the day following the expiration of the statutory limitation period stipulated in the lien legislation applicable to the Place of the Work, or where such legislation does not exist or apply in accordance with such other legislation, industry practice or such other provisions which may be agreed to between the parties, providing that the Owner may retain out of such holdback monies any sums required by law to satisfy any liens against the Work or other monetary claims against the Contractor and enforceable against the Owner and that the Contractor has submitted to the Owner a sworn statement that all accounts for labour, subcontracts, products, construction machinery and equipment and other indebtedness which may have been incurred by the Contractor in the Total Performance of the Work and for which the Owner might in any way be held responsible have been paid in full except holdback monies properly retained. 14.9 If because of climatic or other conditions reasonably beyond the control of the Contractor there are items of work that cannot be performed, payment in full for work which has been performed as certified by the Consultant shall not be withheld or delayed by the Owner on account thereof, but the Owner may withhold until the remaining work is finished only such monies as the Consultant determines are sufficient and reasonable to cover the cost of performing such remaining work and to adequately protect the Owner from claims. 18 eeDe 4 - 1982 File 00720 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 14.10 No payment made by the Owner under this Contract or partial or entire use or occupancy of the Work by the Owner shall constitute an acceptance of work or products which are not in accordance with the re- quirements of the Contract Documents. 14.11 All certificates issued by the Consultant shall be to the best of his knowledge, information and belief.

Giberson of Cosburn Giberson Landscape Architects, a soil investigation was carried out in the parkland of Bowmanville Creek, south of Queen Street, for proposed Park Facilities. The purpose of the investigation was to reveal the subsurface conditions and to determine the engineering properties of the occurring soils for the design and construction. of the proposed project. The findings and resulting geotechnical recommendations are presented in this Report. It should be noted that no tests have been carried out to determine whether environmental contaminants are present in the soils. Therefore, this report deals only with a study of the geotechnical aspects of the proposed project. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-5.57 2 2.0 SITE AND FROmer DESCRIPJ10N Bowmanville is situated on Iroquois Lake plain, where drift has been partly eroded by the water action of the glacial lake and in places filled with lacustrine clay, silt and sand. The project area is adjacent to the Bowmanville Creek valley in the centre of Bowmanville, south of Queen Street It covers a flat area at the top of the north bank of the valley, a sector of the northern valley bank, and a sector on the south bank of the creek. The project consists of a paved parkette and pathway leading to a gazebo on the flat land at the top of the north bank; a stairway on the face of the northern bank; and a pedestrian bridge crossing the creek. The .sector of the bank on which the stairway will be built slopes at about 1.0 vertical:2.0 horizontal with a height of 16.0 metres. A site inspection has shown the face of the valley bank is generally wooded and in a stable conditipn; however, in the sector where the stairway is proposed, snow- dumping has flattened the trees and in places the subsoil is exposed and has been eroded by runoff. I I , I I I I II I I I I I I I I I I I I I ~ Reference No. 9306-S.57 3 3~0 FIELD WORK The field work, consisting of three (3) boreholes to depths ranging from 5.0 to 18.7 m, was performed on July 26, 1993, at the locations shown on the Borehole Location Plans, Drawing Nos. 1 and 2, attached. The holes were advanced to the sampling depths by a track-mounted, continuous- flight power-auger machine equipped for soil sampling. Standard Penetration tests, .,p using the procedures descnoed on the enclosed "Ust of Abbreviations and Terms", were performed at frequent intervals of depth. The test results are recorded as the Standard Penetration Resistance (or 'N' values) of the subsoil. The relative density of the granular strata, and the consistency of the cohesive strata are inferred from the 'N' values. Split-spoon samples were recovered for soil classification and laboratory testing. The field work was supervised and the findings recorded by a Senior Geotechnical Technician. The elevation at each of the borehole locations was determined with reference to the site bench mark shown on Drawing No.1, which has a geodetic elevation of 108.82 metres. I I I I I ,I I I I I I I I I I I I I I ~ Reference No. 9306-$.57 4 4.0 SUBSURFACE CONDmONS Detailed descriptions of the encountered subsurface conditions are presented on the Borehole Logs, comprising Figures 1 to 3, inclusive. The revealed stratigraphy and the engineering properties of the oc~g soils are briefly discussed herein. Beneath a layer of earth fill at the top of the valley bank, strata of sandy silt; silty sand till; and silty clay till were encountered. The latter extends to the toe of the valley bank. On the south bank of the creek an alluvi'1l deposit was encountered above a stratum of silty clay till which is laminated with a stratum of sandy silt. 4.1 Earth Fill The fills consist of silty clay and sandy silt; they are contaminated with bricks, cinders and glass, showing the fill is mixed with construction debris. They may be contaminated with environmentally undesirable material and it will need to be assessed by laboratory testing (chemical). This procedure is not within the terms of reference for this investigation. The fill extends to a depth of 2.1 m in Borehole 1, deepening to 4.6 m towards the top of the banK, as revealed in Borehole 2. The obtained 'N' values are 5 to 16, with a mean of 8 per 30 em of penetration. This shows that the fill was loosely placed; however, it has self-consolidated. The water content of the samples was found to vary from S to 19%, and shows that the fill at the top of the bank is drier than that in the flat area behind the top of the bank. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-$.57 5 In using the fill for engineering purposes, it must be sorted free of debris . contamination and be properly compacted. 4.2 TQPsoil The topsoil was found beneath the earth fill in Borehole 2; it has a thickness of 40 centimetres. Sample examinations show it contains fine roots and is dark brown in colour. indicating it has a high humus content. The organics are highly compressible rendering the topsoil too weak for engineering application. 4.3 Sandy Gravel The sandy gravel contains a trace of silt with occasional plant debris occurring in the upper layers. Sample examinations show the particle sizes of the sand fraction are well graded, and the gravel and sand particles are subangular to rounded in shape. This shows that the sandy gravel is an alluvial deposit and from the resistance to augering the presence of cobbles and boulders in the deposit is inferred. The obtained '~ values are 32 and 40, indicating the relative density of the deposit is dense. The natural water content of the samples was found to be 8 and 9%. The low value shows that due to the perviousness of the material the water drained out as the samples were taken. A grain size analysis was performed on one representative sample and the result is plotted on Figure 4. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-S.57 6 According to the above findings, the other engineering properties are deduced in . the following: Non-frost-susceptible and moderately water erodible. Pervious, with the estimated coefficient of permeability being 10-1 em/sec. A frictional soil, its shear strength is derived from internal friction and is soil density dependent with an estimated internal friction angle of 400. In steep cuts, the dry and wet gravel will slough to its angle of repose (or its internal friction angle), will run with water seepage, and boil with a piezometric head of about 0.8 metre. 4.4 Siltv Sand Till This deposit was encountered in the deep borehole drilled at the top of the bank. It consists of a random mixture of particle sizes ranging from clay to gravel, with sand and silt being the dominant fractions: Its structure is heterogenous, showing the deposit is a glacial till. Sample examinations indicated that the till is cemented and the samples slaked readily when placed in water. The obtained 'N' value is 100 +. This shows that the relative density of the till is very dense, suggesting that it has been highly preconsolidated by past glacial loading. Intermittent hard resistance to augering was encountered, indicating the presence of cobbles and boulders in the stratum. I I I I 1\ I I I I I I I I I I I I I I 'I) Reference No. 9306~S.S7 7 The natural water content of the samples was determined and the results are . plotted on the Borehole Logs. The values range from 5 to 7%, showing the clay is in a damp condition. A grain size analysis was performed on a representative sample and the result is plotted on Figure 4. The gradation shows the till is gravelly. According to the above findings, the following engineering properties of the silty sand till are listed below: Highly frost susceptible and moderately water erodible. Low permeability, with an estimated coefficient being 10"' em/sec. A frictional soil, its shear strength is primarily derived from internal friction, and is augmented by cementation, with an estimated internal friction angle of over 450. It will be stable in steep cuts; however, under prolonged exposure local sheet collapse will likely occur. 4.5 Silty Oay 1ill The silty clay till consists of a random mixture of soils; the particle sizes range from clay to gravel, with the clay fraction exerting the dominant influence on the soil properties. The structure of the till is heterogenous, indicating it is a glacial till. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-$.57 8 Hard resistance was encountered during augering, showing the till is embedded with occasional cobbles and boulders. The consistency of the till was found to be hard. This is confirmed by the eN' values of 67 and 100 plus. The Atterberg Limits of one representative sample and the natural water content of all the samples were determined. The results are plotted on the Borehole Logs and summarized below: Liquid Limit Plastic Limit Natural Water Content 29% 17% 9 to 19% '(mean 13%) The results show that the till is a cohesive material with low plasticity. The natural water content is generally below its plastic limit, confirming the hard consistency disclosed by the 'N' values. A grain size analysis was performed on one representative sample and the result is plotted on Figu!e S. According to the above findings, the following engineering properties are deduced: Moderately frost susceptible and water erodlole. Low permeability, with an estima~d coefficient of about 10-7 em/sec. I I I I I I I I I I I I I I I I I I I - ~ Reference No. 9306-$.57 9 A cohesive soil, its shear strength is primarily derived from consistency which is inversely. related to its moisture content. It contains sand; therefore, its shear strength is augmented by internal fri1fn. It will generally be stable in a relatively steep cut; however, long exposure .<\ will allow infiltrating precipitation to wet thf. soil mantle, and this may lead .,,," to local sloughing. }, 4.6 Sanqy Silt The sandy silt was found in Borehole 1 beneath the earth fill and laminated in the silty clay till in Borehole 3. f .." ,t.' ..,-, Sample examinations showed that the silt found beneath the earth fill (Borehole 1) :J.~ contains silty clay layers. The silt stratum laD\inatCd in the silty clay till occurred in .;g.. the valley (Borehole 3) and contains occasional clay seams. The laminated f~ . structure shows that the revealed silts are lacus~, deposits from a different era. I .'~ They are generally wet and became highly dllataDt.when shaken. The obtained ~ values in the silt found on top of the valley bank varied from 8 to 10, with a mean of 9, and in the sandy silt in the valley, the eN' value is 100 +. The relative density of the silts is thus inferred as loose and very dense. ,.~. ..

A grain size analysis was performed on one representative sample and the result is plotted on Figure 6. According to the above findings, the following engineering properties relating to the project are given below: Highly frost susceptible, with high soil adfreizing potential. Highly water erodible; susceptlDle to migration through small openings under .-II seepage pressure. " '-% Low permeability, with the estimated coefficient being 10"' em/sec. Frictional soils, their shear strength is density dependent. Due to their dilatancy, the strength of the wet silts is susceptlDle to impact disturbance, i.e. the disturbance will induce a build-up of pore pressure within the soil mantle, resulting in soil dilation and a reduction in shear strength. 'i: . In excavation, the moist silts will be stable hi' relatively steep cuts, while the ," wet silts will slough and run slowly with seepage bleeding from the cut face. I,.. They will boil with a piezometric head of 0.4 metre. I I I I I I I I I I I I I I I I , I II I ~ Reference No. 9306-5.57 11 4~6 Compaction Characteristics of the Revealed Solls The obtainable degree of compaction is primarily dependent on the soil moisture and, to a lesser extent, on tbe type of compactor used and the effort applied. As a general guide, the typical water content values of the revealed soils for Standard Proctor compaction are presented below: Table 2 . Estimated Water Content for Compaction I Water Content (%) for Standard Proctor Compaction Determined Natural Soil Type Water Content (%) 100% (optimnm) Range for 95% or + Earth Fill (flat land 12 to 19 14 10 to 16 behind the bank) Earth FilI (top of 5 to 8 14 10 to 16 valley bank) Sandy Silt (top of 22 to 31 13 10 to 17 valley bank) Sandy Silt (in the 15 and 19 13 10 to 17 valley) Silty Clay Tllf 9 to 19 13 10 to 16 (mean 13) Silty Sand Till 5 to 7 10 8to13 Sandy Gravel 8 and 9 10 6 to 15 - -.-. w._."- ..' I I I I I I I I I I I I I I ,I II I I I ~ Reference No. 9306-5.57 12 The above values show that for 95% or + Standard Proctor compaction the earth . fill on top of the bank will require aeration or mixing with the drier fill, and the sandy silt will require aeration. The remaining soils are generally suitable for structural compaction. Densification of the sandy silt, earth fill and sandy gravel should be carried out using a heavy vibratory roller. The intensity of the vibration must be adjusted in accordance with the soil moisture. The tills must be compacted using a heavy kneading-type roller. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-5.57 13 5.0 GROUNDWATER CONDmONS The groundwater level was measured on completion of the boreholes. The data are plotted on the Borehole Logs and tabulated below: Table 3 . Measured Qroundwater Level BH No. Depth (m) BL (m) 1 4.0 103.8 2 Dry 87.4 . 3 1.5 88.5 The groundwater was detected in the loose silt underlying 2.1 m of earth fill and close to the creek where the pervious sandy gravel was saturated by the water in the creek. At the top of the bank the borehole was drilled to a depth level with the bed of the valley; it remained dry on completion. However, the soil became grey at about EI. 97.6, and from this, together with the soil moisture profile, the permanent groundwater regime appears to occur below EI. 94.0. The water measured in Boreholes 1 and 3 is perched in nature, and is derived from infiltrated precipitation which is trapped in the voids in the loose sandy silt or is influenced by the water level in the creek. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-5.57 14 6~O DISCUSSION AND RECOMMENDATIONS The investigation has disclosed that the fiat land behind the top of the north bank of the valley is underlain by a layer of self-consolidated, earth fill extending onto a stratum of loose to compact sandy silt till. At the top of the north bank the earth fill is deeper and beds onto the original topsoil at a depth of 4.6 metres. The natural soils at the bank consist of compact to very dense silty sand till overlying a stratum of silty clay till. At the south bank of the creek an alluvial deposit consisting of dense sandy gravel was encountered. It extends onto a hard silty clay till which is laminated with very dense sandy silt. The groundwater level measured at the fiat land is derived from infiltrated precipitation which is perched at a depth of 4.0 metres. At the top of the bank, no groundwater was detected due to the low permeability of the tills; however, the permanent groundwater level is expected to occur at a depth of 12.0 m (lower sector of the bank). The groundwater level at the south bank of the creek generally corresponds with the water level in the creek. The geotechnical findings and/or constraints which warrant special consideration are presented below: 1. The land at the top of the bank and behind the top of the bank has been covered with a layer of fill. The fill extends to a depth of 2.1 m (Borehole 1) thickening to a depth of 4.2 m (Borehole 2) at the top of the I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-$.57 15 bank (El. 105.7 to 101.5) According to the design drawing (No.1 prepared by Cosburn Giberson), the proposed paved parkette will generally follow the existing contours; therefore, it will be built on the existing fill which was found to contain construction debris and glass. The environmental parameters of the fill should be tested to ensure that it is suitable for parkland use. In addition, the fill is a highly frost-susceptible material, and this should be taken into consideration in the design of the pavement. 2. The foundations of the gazebo and stairway muSt extend at least 1.5 m into the natural bank below the creep zone generally associated with banks sloped at 1.0 vertical:less than 2.5 horizontal. 3. For construction of the pedestrian bridge, the excavation for the abutment should be sheeted to prevent water infiltration. The recommendations appropriate for the project described in Section 2.0 are presented herein. One must be aware that the subsurface conditions may vary between boreholes. Should this become apparent during construction, a geotechnical engineer must be consulted to determine whether the following recommendati~ns require revision. 6.1 Parkette The pavement for the parkette will either consist of paving stone or a concrete slab and will be sensitive to frost heave. The recommended protective schemes are given below: I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-5.57 16 Paving Stone The fill subgrade must be removed to a depth of 1.0 m, replaced with non- frost~susceptible sand, and should be provided with subdrains to prevent water ponding in the sand mantle. Concrete Slab The slab must be insulated with SO mm Styrofoam or equivalent. In preparation of the sand base for the paving stones or granular base for the concrete slab, the fill subgrade must be proof-rolled. The sand base must be uniformly compacted to at least 95% of its maximum Standard Proctor dry density. The concrete slab should be founded on a 15 em granular base which should be compacted to at least 95% of its maximum Standard Proctor'dry density. 6.2 Foundations o~ rrll7~bo and Stairway The existing bank consists of very dense silty sand till overlying a hard silty clay till. The bank slopes at 1.0 vertical:about 2.0 horizontal with a height of 16.0 meters. The very dense till extends to about El. 94.0; the remaining soil consists of very hard silty clay till which extends beyond the toe of the bank, EI. 88.7. This shows . there is no risk of deep-seated failure of the bank and its overall stability is I I I I I I I I I I I I I I I I I I I {l) Reference No. 9306-5.57 17 estimated to be at least 1.4. However, there is creep movement associated with the . surficial zone which is driven by the weathering process. This zone is generally confined within 1.2 m from the face of the bank. The foundations of the gazebo must be extended onto the natural sound soil, Le. the dense silty sand till. The foundations of the stairway must extend below the creep zone and be designed to resist the creep. The foundations must extend at least 3.0 m into the natural soils. According to the findings of Borehole 2, this level lies either in the very dense silty sand till or the hard silty clay till. A Maximum Allowable Soil Pressure of 800 kPa is recommended for normal foundations and 1,500 kPa for drilled caissons. The ratio of the embedded depth to the diameter of the caisson should be at least 2.5:1.0. The recommended soil pressures incorporate a safety factor of three against shear failure of the underlying soils. The total and 4ifferential settlements of the footings are estimated to be less than 25 and 15 111m, respectively. I I I I I I I I I I I I I I I I I I I ~ Reference No. 9306-$.57 18 6.3 Stairway The stairway will be elevated. In places, the underlying silty sand till and silty clay till have been exposed on the face of the bank. These soils are susceptible to water erosion, particularly on a bank; therefore, the face must be well planted to promote the rooting system and vegetative cover which will protect the face against runoff erosion. 6.4 Pedestrian Bridge The foundations of the bridge abutments must be placed beneath the scouring depth of the creek and be provided with adequate earth cover (1.2 m) for protection against frost action. According to the soil data disclosed by Borehole 3, the founding level appears to lie in the dense sandy gravel or the hard silty clay till. In the dense sandy gravel, the foundations must be placed at a level where the material is free of plant debris. The recommended soil bearing pressure for the SLS is 600 kPa for the design of the foundatio~. The corresponding soil bearing pressure for the ULS is 1,800 kPa. The total and differential settlements of the foundations designed with the recommended SLS soil pressure are estimated to be 2S and 15 mm, respectively.

This level lies mostly in the fill. The sewer bedding should consist of 20 mm Crusher-Run limestone; where debris is encountered at the sewer subgrade, it should be removed and replaced with compacted bedding material. The sewer trench should be backfilled with the excavated material, which must be sorted free of construction debris and compacted to 95% of its maximum Standard Proctor dry density. 6.6 Excavation Excavation in excess of 1.2 m should be carried out in accordance with the manner specified in Ontario Regulation 213/91.
