trate or failure of Party B to notify Party k within the ten (10) day

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

the arbitrator or arbitrators may be filed in court to carry it into
effect.

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 inci-
dent 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

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
aubiequent 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 cat: 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,
then the arbitrator need by Party A and the arbitrator named by Party B
shall choose a third arbitrator.

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 inci-
dent 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
(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 is
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 judge that the two
arbitrators originally appointed were unable or failed to act with reason-
able promptness in appointing a third arbitrator, he MkAl 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.

appointed, the arbitrator or arbitrators shall be unable or shall fail

within a reasonable time, Party B) may request a judge of the Unitrsd
States District Court who regularly holds court in the district ir, which
the site of the work, or any part thereof, is located, to ar."cint three
new arbitrators to act hereunder. If it appears to such )edge 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 may appoint three new arbitrators
to act hereunder; and such ar. appointment shall constitute a conolusive.
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 not 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 and are unable or fail to act with reasonable promptness in
reaching a decision regarding the questit.i submitted to arbitration,
then the arbitration procedure shall be deemed to have failed and the
parties shall be free to assert their rights in the same manner 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 forth above.
The Contractor shall not cause a delay of the work during arty 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. -
