The Hydrolec bid price was second to lowest and their energy generation was second to highest However, their powerhouse volume was highest due to the large plan area needed for a double runner Francis 4. The Bouvier machine operates over a flow range of 38-158.7 cfs and the Hydrolec machine operates over a flow range of 81-190 cfs. Based on the enclosed bid evaluation, it is recommended that negotiations be held with Bouvier. The negotiations would be used to resolve questions and clarifications prior to conforming a contract Therefore, these negotiations should only be held if a contract is to be awarded To ensure that the manufacturer can begin fabrication by March 20, 1989, the contract must be awarded by mid-January, 1989 In addition, to avoid repeating the miscommunication that occurred during the Lewisville contract award period over the need for a conformed contract, please advise us as soon as possible regarding the need for conformed contract documents Please note that the City should review all commercial exceptions for acceptability. Black b Veatch has only examined those commercial exceptions with economic consequences We have notified Bouvier that the 15 percent payment upon receipt of contract is not acceptable They have agreed to postpone that first payment to tie it into the 30-day deliverables.

B Dallas will continue to have complete control over determining Dallas' water releases from Ray Roberts Lake through Denton's hydroelectric turbine. Denton will continue to have complete control over determining Denton's water releases from Ray Roberts Lake through subject hydroelectric turbine Such water releases shall be for the purpose of providing a supply of water to the downstream Lewisville Lake water supply reservoir and the water supply for water plants dependent on the water therein The generation of electricity by the hydroelectric unit will be incidental to the water supply releases. The conservation of water for the municipal water system's use is the primary and paramount purpose of water releases, however, Dallas and Denton will take into consideration the needs of the hydroelectric plant where feasible. C Dallas and Denton will each obtain a separate "non-consumptive water right" from the Texas Water Commission for the hydroelectric turbine. Dallas and Denton will have permitted rights for their respective releases, but Dallas will allow Denton's use of its permit for hydroelectric generation as required by Denton's FERC permit and as herein agreed Any costs incurred by Dallas to secure such permits and any annual or other periodic permit fees shall be paid by Denton. Any such permitted right shall be subject to Dallas' and Denton's right to use water for municipal purposes, in the event Dallas' need for municipal purpose requires it, Dallas may discontinue discharge of its water releases which may cause Denton to cease hydroelectric operations D Denton shall work with and support Dallas, if any actions are initiated by the Federal Energy Regulatory Commission or its successor agency and/or other bodies that may attempt to impose jurisdiction or any criteria on Denton or Dallas, resulting from Denton's hydroelectric project, which would have the effect of diminishing Dallas' and/or Denton's water rights or safe yields of Ray Roberts Lake E.

constitutes a change in the contract, but has not been authorized as such by a change order in writing by the Owner, the Contractor shall immedi- ately request a written interim authorization and proceed without delay to perform the work in accordance with such authorization The Contrac- tor shall provide written notice of the claim or dispute to the Engineer and the Owner within 5 days of the request for interim authorization The Contractor's failure to give said written notice within the 5 day period shall constitute a waiver and relinquishment of any such claim or dispute The Owner's

the contract price is required due to a modification which increases the amount of the work, and the added work or any part thereof is of a type and character which can properly and fairly be classified under one or more unit price items of the contract, then the contract price will be increased according to the amount actually done and at the applicable unit price Otherwise, such work shall be paid for as herein- after provided Contract price changes for modifications involving extra work will be based on agreed lump sums or on agreed unit prices whenever the Owner and the Contractor agree upon such prices before the extra work is started, otherwise, payments for extra work will be based on actual direct cost plus a percentage allowance The percentage allowance shall include the Contractor's extra profit and extra overhead, and unless oth- erwise agreed by the Contractor and the Owner the percentage allowance shall be 15 percent of the total direct cost For the purpose of determining whether proposed extra work will be au- thorized, or for determining the payment method for extra work, the Con- tractor shall submit to the Engineer, upon request, a detailed cost estimate for proposed extra work The estimate shall indicate itemized quantities and charges for all elements of direct cost and a percentage allowance to cover extra profit and extra overhead Unless otherwise agreed upon by the Contractor and the Owner the percentage allowance shall be 15 percent of the total direct cost GC 20 1 2 Decreased Price If a change in the contract price is re- quired due to a modification which decreases the amount of work, such decrease shall not constitute the basis for a claim for damages or an- ticipated profits on work affected by such decrease Where the value of omitted work is not covered by applicable unit prices, the Engineer shall determine on an equitable basis the amount of (a) credit due the Owner for contract work as a result of an authorized change, (b) allowance to the Contractor for any actual loss incurred in connection with the pur- chase, delivery, and subsequent disposal of materials or equipment re- quired for use on the work as planned and which could not be used in any part of the work as actually built, and (c) any other adjustment of the contract amount where the method to be used in making such adjustment is not clearly defined in the contract documents GC 20 2 Contract Time Changes The contract time may be changed due to work modifications, hindrances and delays, and work suspensions over which the
