Security of payment basics for designers and consultants

Every Australian state and territory has a security of payment Act for the construction industry. Whether one covers a particular design engagement is a legal question, but knowing which Act applies, and keeping good records, helps either way.

This is general information, not legal advice. Whether a security of payment Act applies depends on your contract, your state and the type of project; jobs for owner-occupiers are often treated differently. Time limits under these Acts are strict. Get advice before relying on one.

What these laws generally do

In broad terms, these Acts give people who carry out construction work, or supply related goods and services under a construction contract, a right to progress payments and a fast adjudication process for disputed amounts, so that money keeps moving while bigger disputes are resolved. The details, including who is covered, what a valid claim looks like and the deadlines at each step, differ between Acts.

Design services: one clear example

Coverage of design work isn’t uniform, and we only state what we could verify. The NSW Act is explicit: section 6 lists “architectural, design, surveying or quantity surveying services in relation to construction work” as related services. For other states, read the definitions in the Act itself or get advice.

Records worth keeping on every job

  • The accepted fee proposal, with stages, fees and triggers (how to write one).
  • Each stage invoice, with its date and the work it covers (staged invoicing).
  • Written approvals of variations, with dates.
  • Payment records: what was paid, when, and against which invoice.
  • For shared jobs, which consultant supplied which part, and to whom (split payments).

What DrafterShare does and doesn’t do

DrafterShare is planned to keep exactly those records: the accepted schedule, stage invoices, variations and payments in one place. It is not planned to prepare or serve payment claims, payment schedules or adjudication applications under any security of payment Act. For those, use your state regulator’s guidance and get advice. Try the live demo to see the records it keeps.

Questions

Does a security of payment Act cover my design fees?

It depends on your state’s Act, your contract and the project. The NSW Act expressly includes design services as related services; for other states, read the Act or get advice.

What are the deadlines for a claim?

They vary by Act and by step and are strictly applied, so we don’t summarise them. Check the current Act and your regulator’s guidance.

Can DrafterShare make a payment claim for me?

No. It is not planned to prepare or serve payment claims under any security of payment Act.

Help shape it before launch

We are looking for a small group of Australian design practices and consultants to pilot this on one or two real projects.
