1.46.6 Procedure for Expert Determination
When the person to be the Expert has been agreed or nominated, the Principal, on behalf of both parties will request the Expert to sign an agreement. The agreement will set out the claims and the questions upon which the Expert is asked to give an opinion (the Expert's determination), and the Expert's fees and will state that these are the procedures to be adopted by the Expert and the parties. The date upon which the Expert signs the agreement shall be the "Date of Commencement".
The parties shall share equally the Expert's fees and shall bear their own costs.
If, as a term of accepting the appointment, the Expert has requested security for costs, the parties shall deposit an equal share of the security.
The Expert is not an arbitrator and shall not be liable for any act or omission done bona fide in the exercise or purported exercise of functions as an expert.
The parties shall make submissions to the Expert as follows:
(a) Within 14 days after the Date of Commencement, the claimant will make a written submission setting out details of the claimant's claim.
(b) Within 21 days after receipt of a copy of that submission, the other party must make a written response. That response can include cross-claims.
(c) Within 21 days after receipt of the response, the claimant may reply to the response but must not raise new matters.
(d) Within 14 days after receipt of that reply, the other party may make comments upon the reply but not raise new matters.
For the purpose of counting days under (a) to (d) public holidays and the period from 24 December to 15 January inclusive shall not be counted.
All submissions must be in writing. Unless the Expert and the parties otherwise agree, the Expert must ignore any submission made later than the time prescribed. A party providing anything to the Expert must at the same time provide a copy to the other party.
The Expert may request further information from either party. The request must be in writing and must provide a time limit for any response. The Expert must send a copy to the other party and give the other party a reasonable opportunity to comment on the response.
Provided that the parties agree, at the request of the Expert an on such terms as the parties may agree, the Expert may arrange a conference. With any request for a conference, the Expert must set out the matters which the Expert wants to discuss at the conference. Any such conference shall be "Without Prejudice".
Within 12 weeks after the Date of Commencement, the Expert must deliver to the parties the Expert's written opinion on the questions referred. Unless the parties agree to extend this time, the Expert cannot deliver a determination after that time. With the determination, the Expert must provide a statement of reasons. If the determination contains clerical or mathematical errors or accidental slips or omissions, the Expert can correct them even after expiration of the time for making the determination.
The process is not arbitration. The Expert must make the determination on the basis of the submissions of the parties, including documents and witness statements, and the Expert's own expertise.
1.46.7 Arbitration
Where the Principal or the Contractor is entitled, pursuant to Clause 1.46.5, to give notice requiring a dispute to be referred to arbitration, such notice ("Notice") shall:

(c) if given by the Principal, be signed by the authorised delegate of the Principal; and

Arbitration will be conducted under the Commercial Arbitration Act NSW 1984 (as amended) (Act) subject to the following:
1. With reference to section 14 of the Act, the arbitrator must conduct proceedings in accordance with this clause 46.7, which overrides section 14 of the Act.
