Adjudication Process​

 Download the How to Guide: Viewing the Adjudication Process

Once an Adjudicator is appointed, the Adjudicator will contact the Parties to set the adjudication process. The Adjudicator will conduct the adjudication in the manner the Adjudicator determines appropriate, in accordance with s. 13.12(4) of the Construction ActSome adjudications may include a hearing by videoconference, some may have an in-person hearing, some may require a site visit, and some may proceed only with documents. Factors Adjudicators may consider (when deciding on the appropriate process) include:  

  • the amount in dispute;
  • whether an oral hearing is necessary to determine facts; and
  • whether a site visit is necessary.

Pre-Designed Adjudication Processes

Even though the Adjudicator will set the process, the Parties may want to suggest a process to the Adjudicator.  To assist the Parties, ODACC has set out four samples of Suggested Pre-Designed Adjudication Processes that the Parties may choose to recommend to the Adjudicator (and/or the Adjudicator may choose to set). Three of the Pre-Designed Adjudication Processes take place in-writing only, while the fourth provides Parties with an oral hearing (by videoconference or teleconference).

The Claimant may indicate a preferred process in the Notice of Adjudication. Similarly, the Respondent may indicate a preferred process in the Response to Notice of Adjudication.

When recommending a process to the Adjudicator, the Claimant and Respondent should consider the amount claimed to ensure that the cost of the adjudication will be proportionate to the amount in dispute. They should also consider the complexity of the issue in dispute. Disputes involving lower amounts or less complicated issues, for example, may be able to be resolved using a Pre-designed Adjudication Process.

The Parties may also recommend that the Adjudicator design the adjudication process without being guided by the Pre-Designed Adjudication Processes.

Fees for Pre-Designed Adjudication Processes

The Adjudication Fee for the Pre-Designed Adjudication Processes are negotiated between the Parties and the Adjudicator. If there is no agreement on the Adjudication fee, the Adjudication fee will be set by ODACC.

ODACC has also provided suggested Adjudication Fees for each Pre-designed Process.

The four Pre-Designed Adjudication Processes are as follows:

  • Adjudication in writing only;
  • Submission of Parties’ arguments is limited to two pages per Party not including a copy of the construction contract or subcontract (which must be submitted) and a copy of the disputed invoice (which may also be submitted) and any documents the party intends to rely on during the adjudication; and
  • Determination is expected to be approximately five pages.

Powers of Adjudicator

During the adjudication, the Adjudicator may issue directions with respect to the conduct of the adjudication and may:

  • take the initiative in ascertaining the relevant facts and law; and
  • draw inferences based on the parties’ conduct.

The Adjudicator may also set an oral hearing, a site visit, and/or request the assistance of a person to determine better any matter of fact in question.

Adjudicators may set an oral hearing (in person, by videoconference or by teleconference) (s. 13.12 (1) of the Construction Act). The Adjudicator will organize the oral hearing and provide the Parties with the required information.

Adjudicators may decide that there should be a site visit of the Improvement. Adjudicators will arrange with the Parties to conduct the site visit (subject to the Owner’s consent). For further information, refer to s.13.12(2) of the Construction Act.

The Adjudicator may obtain the assistance of an expert, including “a merchant, accountant, actuary, building contractor, architect, engineer or other person in such a way as the Adjudicator considers fit, as is reasonably necessary to enable him or her to better determine any matter of fact in question” (s. 13.12(1) 5. of the Construction Act). 

The Adjudicator is able to order that one or both parties pay the expert’s fees (s. 13.12(3) of the Construction Act).
