Construction Site Signs Sydney — ACP Site Boards & Builder Signage

If you're running a building project in NSW, construction site signs aren't optional — they're a legal requirement. Every principal contractor must display a sign on site showing their name and contact number.

​

Beyond compliance, your site signage is your most visible on-street branding. We recently completed 10 ACP site boards for a Northern Beaches building company across multiple sites — one sign or a full development pipeline, we can help.

LEGAL REQUIREMENTS

1. The mandatory builder sign: what NSW law requires

What signs are legally required on a construction site in NSW?

 

Under WHS Regulations 2017 — mandatory for all principal contractors:

  • The principal contractor's name

  • A contact telephone number — including an after-hours number

  • The location of the site office, if one exists on site

Sign must be clearly visible from outside the workplace. Licensed residential builders must also display their registration number under NSW building registration legislation.

​

What information should go on a builder sign in NSW?

  • Builder's or principal contractor's full trading name

  • NSW builder's licence or contractor's licence number

  • Contact phone — business hours and after-hours

  • Website address

  • Company logo and brand colours

  • Project name or address (useful for multi-site builders)

DA conditions sometimes specify additional information — DA number, certifier's details, or approved hours of work. Always check your DA conditions before finalising artwork, as requirements vary across Northern Beaches Council, City of Sydney, and other LGAs.

​

How big does a builder sign need to be?

The WHS Regulations require the sign to be "clearly visible from outside the workplace." For a standard residential project, 600×900mm is a commonly used minimum. For larger commercial or multi-residential developments with more passing traffic, 900×1200mm or larger is more appropriate. We produce to custom dimensions as well as standard sizes.

SIGN TYPES

2. Types of construction site signage

Construction site mock up sign to showcase on signage website

Project signboards & developer boards

The first thing anyone sees at a site. Meets legal requirements and markets the development to everyone who walks or drives past — builder name, logo, project name, render, and completion date.

Hoarding & fence signage

Construction hoardings represent a large, visible surface area most builders underutilise. Project branding, development information, and community messaging across the full site perimeter.

MATERIALS

3. ACP vs corflute: choosing the right material

Why ACP is the right choice for most construction site signs

ACP — Aluminium Composite Panel

  • 5–7 year outdoor life with UV-stable print and laminate

  • Rigid, flat, weather-resistant — handles coastal conditions

  • Professional finish — sharp full-colour print that reflects the builder's brand

  • Reusable across multiple sites

  • Right choice for mandatory contractor sign and project boards

Corflute — Corrugated Plastic

  • Weeks to months outdoors — not suited for project duration

  • Fades, becomes brittle under coastal UV exposure

  • Affordable for short-term site directionals and temporary notices

  • Not reusable in the same way as ACP

  • Not appropriate for mandatory contractor or project board

Can ACP site signs be reused across multiple projects?

Yes — this is one of the practical advantages of ACP for builders running multiple sites. A standard ACP board with your company name, logo, licence number, and contact details can move from site to site without modification. Project-specific elements (development name, render, completion date) can be updated with a new vinyl layer over the existing sign. We recently produced 10 ACP site boards for a Northern Beaches building company for exactly this reason — a set of quality boards that travel with you is significantly more cost-effective over time than fresh corflute for every build.

DEVELOPER BRANDING

4. Developer branding and project boards

Making your project board work harder

For developers and project builders where the finished product will be sold or leased, the construction site sign reaches every person who passes during the build — potentially thousands over a 12-month project. Elements that make a project board perform beyond its compliance function:

  • A high-quality render or architectural image of the finished project

  • A clear, memorable, and searchable project name

  • A website URL or QR code for people who want to know more

  • Clean, professional typography matching the development's brand

  • Architect and consultant branding if contractually required

  • Expected completion date or "coming soon" messaging

Consistent branding across a building company's pipeline

For building companies running multiple simultaneous projects, brand consistency across site boards builds recognition across the local market. Every site is a billboard for the company. We hold your artwork files and can produce replacement or additional boards to the same specification whenever you need them — if your logo or contact details change, we update the file and produce fresh boards across your whole fleet.

PRICING

5. Pricing and how to get a quote

Every construction site sign job is different

Construction site sign pricing depends on the number of signs, dimensions, artwork complexity, substrate, and whether any updates to existing boards are needed. We don't publish set prices because a quote without knowing your specific requirements wouldn't be accurate. What we can tell you is that ACP site boards are a one-time cost that earns its keep across multiple projects — the durability and reusability make the per-project cost very competitive compared to ordering fresh corflute for every build.

​

What affects the cost

  • Number of signs in the order

  • Size — standard vs custom dimensions

  • Design — print-ready artwork vs design assistance needed

  • Substrate — standard 3mm ACP vs heavier gauge

  • Complexity — builder details only vs full-colour developer project board with render

  • Mounting hardware — eyelets, hanging systems, or stake fittings

Getting a quote

Contact us with the number of signs you need, your standard sizes (or DA-specified dimensions), and any existing artwork or brand guidelines. If you have an active site that needs a sign urgently, tell us and we'll confirm what's achievable on a fast turnaround. We aim to respond within one business day.

FAQ

Frequently asked questions

Everything you need to know before getting in touch.

Under the Work Health and Safety Regulations 2017, principal contractors must display a sign showing their name, a contact telephone number including after-hours, and the location of the site office — clearly visible from outside the workplace. Licensed residential builders must also display their registration number under NSW building registration legislation. Beyond the mandatory contractor sign, safety signage under AS 1319 is required for hazards on site, including entry restrictions, PPE requirements, and hazard-specific warnings.

What signs are legally required on a construction site in NSW?

How long do ACP site signs last on a construction site?

A well-produced ACP sign with UV-stable inks and UV laminate will typically last 5–7 years in outdoor Australian conditions, making it reusable across multiple construction projects. Coastal Northern Beaches locations — direct UV and salt air — are demanding, but quality ACP specified for outdoor use handles this environment well. The main indicators that an ACP sign needs replacing are faded or sunburnt print, delaminating edges, or physical damage. With normal care, an ACP builder sign can move with you from project to project for years.

What's the difference between corflute and ACP for building site signs?

Corflute is a lightweight corrugated plastic — affordable and weatherproof for short-term applications, but not designed for the UV exposure and duration of a multi-month construction project. ACP (aluminium composite panel) is rigid, flat, UV-stable, and built for long-term outdoor use — it handles coastal conditions, resists warping and delamination, and takes full-colour print at a quality that reflects well on a builder's brand. For mandatory principal contractor signs and project boards, ACP is the correct substrate. Corflute suits short-term directional and temporary signage on site.

Can I reuse my ACP site boards across multiple projects?

Yes — reusability is one of the main practical advantages of ACP over corflute for builders running multiple sites. A standard ACP board with your company name, logo, licence number, and contact details travels from project to project without modification. For project-specific boards, elements can be updated with a new vinyl layer. We hold your artwork files so repeat orders and updates are quick. For builders with five or more concurrent sites, a set of quality ACP boards quickly pays for itself compared to fresh signage for every project.

What information must be on a builder sign in NSW?

The legal minimum under WHS Regulations is: the principal contractor's name, a contact phone number including after-hours, and the site office location if one exists. Licensed residential builders are also required to display their licence number. In practice, most builders include their trading name, logo, website, and licence number as standard. DA conditions may require additional information such as the DA number, certifier details, or approved construction hours — always check your DA conditions before finalising sign artwork.

Do you produce safety signs for construction sites as well as project boards?

Yes — we produce both. Safety signs to AS 1319 standards (prohibition, mandatory, warning, and emergency information signs) are part of what we supply for construction sites. If you want to brief us on a complete site signage package — mandatory contractor sign, project board, and safety signage — we can quote the whole job together. For ongoing workplace safety signage once the construction phase is complete, our wayfinding and safety signs service covers that next stage.

How quickly can you produce construction site signs?

Turnaround depends on complexity and whether you have print-ready artwork. For a standard ACP builder sign with your existing logo and contact details, we can often produce quickly once artwork is confirmed — contact us with your timeline and we'll give you an honest estimate. If you have an urgent need — an active site that's not yet signed — tell us when you enquire and we'll do our best to accommodate you.

Can you match my existing brand guidelines for the site boards?

Yes — we work from whatever artwork and brand guidelines you supply. A logo in vector format (AI, EPS, or PDF with outlined text) and any colour specifications gives us the ideal starting point. If you only have a low-resolution file, we can advise on whether it'll reproduce cleanly at the required size and connect you with a trusted local designer if needed. Consistency between your site boards, your vehicle graphics, and your other materials is something we actively help you maintain.
