Subjects Marley Company Proposal
Municipal Electric
Generating Station
Unit fS
Dear Sir!
We wish to clarify Marley's Proposal of July 6, 1970 and offer the following
alternates.
Since we took no exceptions to the specifications, we were offering 1 1/2"
x 6" Tongue and Groove Treated Lumber for the fan deck but Inadvertently called
out 1 1/8".
If Marley should be allowed to furnish 1 1/8" treated laminated exterior fir
for the faa deck, the deduction will be $20000.00.
If the City wishes to use 8 carbon steel drive shafts and 4 carbon steel shafts
in the 046 intermediate bearings, you may deduct $5,320.00 from the propose!.
If these shafts are to be epoxy coated, the addition will be $800.00 or a net
` deduct of $4,5:0.00.
If the Bypass Type Oil Filters with replaceable cartridges are omitted from
the Gearaducers, a deduction of $240.00 each or $960.40 will be allowed.
If 14' high Marley Molded Fiber Glass Reinforced rolyester Pan Cylinders are
furnished rather than the 18' high as offered, a deduction of $I,300.00 each
or $6,000.00 will 1~e allowed.
Since many of the maintenance tools such as tripod, dolly, track, etc., are
duplicates of what was furnished on the Marley Tower serving Unit 04, a deduction
of $1,200.00 can be allowed if not ordered.
Please let us know if you need any additional infor•aation.
Yours very truly,

a decision of the Engineer, the objector (hereinafter referred to as
Party A) to the decision shall first offer to arbitrate the question
with the other party to the contract (hereinafter referred to as Party

question to be arbitrated.
Party B can elect to arbitrate or not. If Party B agrees to arbitrate
he shall so advise Party A in writing within ten (10) days after receipt
of Party A's notice. Notice by Party B that he does not wish to arbi-
trate or failure of Party B to notify Party A ~iithin the ten (10) day
period will give Party A the right to start action in court.
If Party B AGrccs to arbitrate, Party A shall choose an arbitrator and
shall notify Party B of the name of the arbitrator within ten (10) days
after receipt of Party B's notice. Party B shall notify Party A in
writing within ten (10) days after receipt of the said notice that the
arbitrator named by Party A shall act as sole arbitrator, or shall name
an additional arbitrator. If Party B names an additional arbitrator, j
then the arbitrator named by Party A and the arbitrator named by Party B

of three arbitrators, the decision of any two shall be binding on both
parties to the contract, as shall that of a single arbitrator if the
dispute is submitted thereto as heretofore provided. The decision of
the arbitrator or arbitrators may be filed in court to carry it into
effect.
If they consider that the case so demands, the arbitrator or arbitrators
are authorized to award the party whose contention is sustained such sum
or sums as they may deem proper for the time, expense and trouble incident
to the appeal, and if the appeal was taken without reasonable cause, they
may award damages for any delay occasioned thereby. The arbitrators shall
receive reasonable compensation for their services. The arbitrators shall
assess the costs and charges of the arbitration upon either or both parties.
The decision of the arbitrators must be made in writing, and shall not be
open to objection on account of the form of proceedings or award.

act with reasonable promptness in appointing a third arbitrator, Party A

a judge of the United States District Court. who regularly holds court in
the district in which the site of the work, or any part thereof, is located,
to appoint the third arbitrator. If it appears to the ,fudge that the two
arbitrators originally appointed were unable or failed to act with reason-
able promptness in appointing a third arbitrator, he may appoint the third
arbitrator, and such appointment shall constitute a conclusive determination
that the arbitrators originally appointed were so unable or failed to act
with reasonable prcmptness and, if the said fudge acted at the re nest of
Party B, that Farty A did not make such request within a reasonable time.
If for any reason after the arbitrator or arbitrators have been duly
appointed, the arbitrator or arbitrators shall be unable or shall fail
to act with reasonable promptness in reaching a decision regarding the
question submitted to arbitration, Party A (or, if he does not do so
within a reasonable time, Party B) may request a judge of the United
States District Court who regularly holds court in the district in which
the site of the work, or any part thereof, is located, to appoint three
new arbitrators to act hereunder. If it appears to such judge that the
arbitrator or arbitrators originally appointed were unable or failed to
act with reasonable promptness in reaching a decision regarding the
question submitted to arbitration, he nay appoint three new arbitrators
to art hereunder, and such an appointme±.t shall constitute a conclusive
determination that the arbitrator or arbitrators originally appointed
were so unable or failed to act with reasonable promptness and, if the
said judge acted at request of Party B, that Party A did rot make such
request within a reasonable time.
If for any reason a third arbitrator or three new arbitrators shall not
be appointed by a judge of the United States District Court under the
circumstances hereinabove described, or if three new arbitrators are so
appointed anri are ,anable or fail to act with reasonable promptness in
reaching a decision regarding the question submitted +o arbitration,
then the arbitration procedure shall be deemed to have failed and the
parties shall be free to assert their rights in the sane r,anner as if
they had not agreed to submit the question to arbitration.
If the above agreement to submit questions of dispute to arbitration is
not enforceable under the law of applicable ,jurisdiction, each such
question after it. has arisen may by agreement of both parties hereto be
submitted to arbitration in the manner set fortis above.
The Contractor shall not cause a delay of the work during any arbitration
proceedings, except by agreement with the Owner. It is understood and
agreed by the parties to the contract that no requirement or statement
herein shall be interpreted as curtailing the power of the Engineer to

Dear Sire
We wish to clarify Harley's Proposal of July 6, 1970 and offer the following
alternates.
Since we took no exceptions to the specifications, we were offering 1 1/2"
x 6" Tongue and 6`roove Treated Lumber for the fan deck but inadvertently called
out 1 1/8".
If Harley should be allowed to furnish 1 1/8" treated laminated exterior fir
for the fan deck, the deduction will be $20000.00.
If the City wishes to use 8 carbon steel drive shafts and 4 carbon steel shafte
in the 046 intermediate bearings, you may deduct $30320.00 from the proposal.
If these shafts are to be epoxy coated, the addition will be $800.00 or a net
deduct of $40520.00.
