Find an appointor

This page is for: 

This information applies to construction contracts entered into before 1 August 2022.  For contracts entered into on or after 1 August 2022 see the Building and Construction Industry (Security of Payment) Act 2021 webpages.

The Construction Contracts Regulations 2004 provide that for the purposes of the definition of 'prescribed appointor' in section 3 of the Act, the persons listed below are prescribed and active:

Adjudicate Today Pty Ltd – ABN 39 109 605 021

Address: Level 28, AMP Tower, 140 St Georges Terrace, PERTH WA 6000
Phone: 1300 760 297
Fax: 1300 760 220


Application/Appointment fee $Nil

Fixed fees, and where appointed by Adjudicate Today and at the request of the applicant:

Value of payment claim (GST inclusive) Maximum adjudicator fee payable (GST inclusive)
Up to $15,000 $1,089
$15,001 to $25,000 $2,178
$25,001 to $40,000 $3,300

Above $40,000, and where appointed by Adjudicate Today:

Grade of Adjudicator Hourly rate (GST inclusive)
Grade 1 $285
Grade 2 $375
Senior or Chief $450

When appointed by agreement of the parties, the hourly rate is that nominated by the adjudicator on the Building Commission website.

Only experienced adjudicators are appointed Grade 2 or Senior. The majority of small value claims are completed in 12 hours or less however large claims; multiple claims; claims in which the respondent argues the dispute is outside the jurisdiction of the Act and/or raises other complex legal arguments; poorly presented claims or responses; or claims in which parties request conferences or inspections can exceed 12 hours.

It is wrong to assume that senior adjudicators will necessarily be more expensive. Our practical experience is that the more senior the adjudicator, the less time is required to finalise a determination. Adjudicators do not bill for a minimum number of hours. Only actual hours worked are billed.

The adjudicator pays Adjudicate Today a service fee which includes the cost of processing and administration of adjudication matters, collecting fees, paying of staff, overheads for 7 offices across Australia and the promotion of security of payment Acts and adjudication generally. The service fee is one-third of the adjudicator's fee and is paid by the adjudicator from the adjudicator fee. It is not an additional fee to parties. An Adjudicate Today adjudicator does not bill extra time to cover the cost of the service fee or for administrative time.
