4.03 CLAIMS AND DISPUTES

A. Definition. A Claim is a demand or assertion by one of the parties seeking, as a matter of right, adjustment or interpretation of Contract terms, payment of money, extension of time or other relief with respect to the terms of the Contract. The term "Claim" also includes other disputes and matters in question between the Owner and Contractor arising out of or relating to the Contract. Claims must be made by written notice. The responsibility to substantiate Claims shall rest with the party making the Claim.

B. Claims by either party must be made within 21 days after occurrence of the event giving rise to such Claim or within 21 days after the claimant first recognizes the condition giving rise to the Claim, whichever is later. Claims must be made by written notice. An additional Claim made after the initial Claim has been implemented by Change Order will not be considered unless submitted in a timely manner.

C. Should concealed conditions encountered in the performance of the Work below the surface of the ground, or should concealed or unknown conditions in an existing structure be at variance with the conditions indicated by the Contract Documents, or should unknown physical conditions below the surface of the ground or concealed or unknown conditions in an existing structure of an unusual nature be encountered, which conditions differ materially from those ordinarily encountered and generally recognized as inherent in the Work of the character provided for in this Contract, and which will be considered by the Contractor as the basis for a Claim for extra compensation, the Contractor shall immediately notify the Owner of the alleged condition or variance before such conditions are disturbed. By failing to give such notice, the Contractor shall waive all rights to extra compensation of any kind arising out of the unusual conditions. The Owner shall investigate the unusual conditions promptly upon receipt of Contractor's notice and shall determine the Contractor's right to additional compensation and/or additional time. Any and all such changes in Contract Sum or Contract Time arising out of the discovery of unusual conditions shall be treated in accordance with the provisions of this Article.

4.04 ARBITRATION

A. Any questions raised about a decision of the Owner may be submitted to arbitration by mutual agreement of the parties to the Contract.

Any request for arbitration shall be in writing, shall state the dollar amount of the request and shall be delivered to the Owner and any adverse party either by personal delivery or by registered mail addressed to the last known address of each within ten (10) days of receipt of the Owner's decision, and in no event after

07/23/2025 final payment has been made and accepted, subject, however, to any express stipulation to the contrary in the Contract Documents.

B. No request for arbitration of any claim, dispute, or other matter may be made until the earlier of

(1) the date on which the Design Professional has rendered a written recommendation, or (2) the tenth day after the parties have presented their evidence to the Design Professional or have been given a reasonable opportunity to do so, if the Design Professional has not rendered a written recommendation by that date.

C. If the parties mutually agree to arbitration, and the parties and the DOE’s assigned Counsel have agreed to a maximum allowable award, the parties shall sign and acknowledge a written agreement specifying what demands are to be submitted to the arbitrators, and the arbitration proceeding shall be limited to such demands.

D. If the parties mutually agree, the arbitration may be carried out in accordance with the Construction Industry Arbitration Rules of the American Arbitration Association. Otherwise, the following procedure shall be followed:

1. if the parties agree, there may be one arbitrator; otherwise there shall be three, one named in writing by each party to this Contract and the third chosen by these two arbitrators. If they fail to select a third within fifteen (15) days, then such arbitrator shall be chosen by the presiding officer of the state or county bar association nearest to the location of the Work. Should the party requesting arbitration fail to name an arbitrator within ten (10) days of its demand, its right to arbitration shall lapse. Should the other party fail to choose an arbitrator within the said ten (10) days then such presiding officer shall appoint such arbitrator. Should either party refuse or neglect to supply the arbitrators with any papers or information demanded in writing, the arbitrators are empowered by both parties to proceed ex parte;

2. no one shall be qualified to act as an arbitrator who has, directly or indirectly, any financial interest in the Contract or the Work or who has any business or family relationship with the Owner, the Contractor, or the Owner's Representative. Each arbitrator selected shall be qualified by experience and knowledge of the Work involved in the matter to be submitted to arbitration;

3. if there be one arbitrator, the award shall be binding; if three, the award of any two shall be binding and may be impeached only for fraud or mistake. Such award shall be a condition precedent to any right of legal action;

4. the arbitrators, if they deem that the case demands it, are authorized to award to the party whose contention is sustained such sums as they shall deem proper for the time, expense and trouble incident to the arbitration and, if the arbitration was taken without reasonable cause, damages for delay;

5. if there is no provision in the arbitration agreement respecting costs and compensation of arbitrators, the arbitrators shall fix their own compensation, and shall assess the costs of the arbitration upon either or both parties;

6. the award of the arbitrators shall be in writing and it shall not be open to objection on account of the form of the proceeding or the award.
