nor any extension of tine, nor any uosseosion taken by the Owner or its
employees, shall operate as a waiver of any provision of this contract,

of the contract. Modifications may involve increases or decreases in the
amount of the worn for which an appropriate contract price adjustment will

adjustment or other monetary consideration, all modifications shall be
made under the authority of duly executed change orders i.ssuQd and signe_j
by the Owner and accepted and signed by the Contractor.
GC-14.01. Extra Work. If a modification increases the amount of the work,

or prices. Otherwise, such work shall be paid for as hereinafter provided.
Claims for extra work will not be paid unless the work covered by such
claims was authorized in writing by the Owner and the Contractor shall not
have the right to prosecute or maintain either an arbitration proceeding
or an action in court to recover for extra work unless his claim is based
upon a written order from the Owner. Fayments for extra work shall be

crease. 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 not done as a
result of an authorized change, (b) allowance to the Contractor for
any actual loss incurred in connection with the purchase, delivery and
subsequent disposal of materials or equipment required 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.

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 within the ten (10) day
period will give Party A the right to start action in court.
If Party B agrees 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,
Vien the arbitrator named by Party A and the arbitrator named by Party B
shall choose s third arbitrator.
The arbitrator or arbitrators shall act with promptness. In the case
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 t; sutmitted therc',o as heretofore provided. The decision of
the arbitrator or arbitrators may be filed in court to carry it into
affect.
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 3ccasioned thereby. The arbitrators shall
receive reasonable compemaation 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.

end Party tl, the arbitrators appointed shall be unable or• shall fail to
act with reasonable pr1riptness in appointing a third arbitrator, Party A
(or, it' 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 the third arbitrator. If it appears to th(. Judge that the two
arbitrators originally appointed were unable or failea 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 promptness and, if the said judge acted at the request of
Party B, that Party 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 s«ch ,judge that the
arbitrator or arbitrators originally appointed were unable ar failed to
act with reasonable promptness in reaching a decision regarding the
question submitted to arbitration, he may appoint three new arbitrators
to act hereunder, and such an appointment shall constitute a conclusive
determination that the arbitrator or arbitrators originally appointed
were so unable or failed to act with reasonable promptnesa and, if the
said ,judga acted at request of Party B, that Party A did not make such
request within a reasonable time.
If for any reason a third arbitrator or three new arbitrators shall rot
be appointed by a Judge of the United States District Court under the
circumstances horeinabove described, or if three new arbitrators are so
appointed and are unable or fail to act with reasonable promptness in
reaching a ar-,ision regarding the question sub..nitted to arbitration,
then the arbitrat?on procedure shall be deemed to have failed an,-.1 the
parties shall bc- free to assert their rights in the c -anner as if
they had not agreed to submit t,.e question to arbitration.
If the above agreement to submit questions of dispute *.o arbitration is
not enforceable under the law of applicable ,jurisdicti"n, each such
question after it has arisen may by agreement of both parties hereto be
submitted to arbitration in the manner set forth 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
determine the amount, quality, and acceptability, of work and materials.

Group P-B No stress relieving required
When dissimilar materials are joined by welding, stress relieving shall be
that specified herein for the naterial requiring the higher stress reliev-
ing temperature except if either material has 2 per cent or less chromium
the stress relieving temperature shall not exceed 1400 F.
* Stress relieving is not required for chromium alloy steel piping meeting
all of the following requirements:
Chromium content not greater than. 3 per cent
Nominal pipe sizes 3 inches and smaller
Wall thickness less then 112 inch
(DENTON, TEXAS - 4904 )
(STEAM GENERATOR - M-34A) 3B-5
Full or partial stress relieving operations shall be started incoediately
after completion of each weld for steels having a chromium content greater
thrui 3 per cent. Stress relieving operations may he delayed for other ma-
terials provided that the welding zone is allowed to cool slowly under an
asbestos wrapping.
For full stress relieving, the holding time at the eheeified stress relieving
tempratures shall be one hour per inch of wall thickness, a minimum of
one-half hour for carbon steels and one hour for allot/ steels.
For partial stress relieving, the holding time shall be one-hour hour mini-
mum. Temperature for partial stress relieving shall be as specified above
for full stress relieving except the temperature need not exceed 1200 F for
any material.
Wherever possible, the entire assembly shall be slowly heated to the speci-
fied temperature, holding the temperature for the required length of time,
then allowing the assembly to cool. Where this procedure is impractical
local stress relieving may be employed. In these cases a circumferential
band around the pipe shall be slowly heated and held to the temperatures
specified. The heated circumferential band shall extend on each side of
the weld a minimum distance equal to twice the pipe wall thickness. The
rate of cooling after the holding period shall be as uniform as possible
and shall not exceed 500 F per hour while the metal temperature is above
600 F.
Sections of pipe containing flow nozzles shall not be full furnace stress
relieved.
Heating may be by means of electric induction coils, electric resistance
coils, or suitable gas burners. Oxyacetylene flame heating will not be
permitted. In addition, where local stress relieving is employed, a com-
plete record of the pipe temperatures throughout the stress relieving cycle
shall be made by means of a recording potentiometer.
No stress relieving for seal welds or strength welds for temperature well
installations will be required.,
