Termite Risk Management On A New Build: The Hidden Item In Your Site Works

TERMITE PROTECTION BELONGS IN YOUR BUILDING BUDGET.Confirm site risks, systems and responsibilities before construction.

Termite protection is the line item that never appears in a glossy feasibility and always appears in a compliance file. It is installed under the slab, it carries a design life, it must be documented on a notice fixed to the building, and it comes with a maintenance obligation the buyer inherits. Developers who skip it lose it at certification; developers who install it and forget the documentation lose it at handover.

Here is the practical version. The National Construction Code treats termite risk management as part of site preparation, not as an optional extra, and it sets out both when it applies and what a compliant system must include.

The deal question: does this site need termite protection at all?

Start with the trigger, because it is narrower than people assume. The Housing Provisions state that the requirements of the Part apply where a Class 1 or 10 building is constructed in an area where subterranean termites are known to present a potential risk of attack, and a primary building element of the building is considered susceptible to termite attack. Both limbs have to be met.

The same Part then explains what counts as not susceptible. A primary building element consisting entirely of, or a combination of, steel, aluminium or other metals, concrete, masonry, fibre-reinforced cement, termite-resistant timber under Appendix C of AS 3660.1, or preservative-treated timber under Appendix D is treated as not subject to termite attack. Practically, this means the choice of structure changes the obligation: a steel-framed house on a slab has a different profile from a timber-framed one.

The Part also carries an explanatory note that matters more than any marketing claim: termites are not considered to be a risk in Tasmania and a lesser risk in parts of Victoria, and the appropriate authority may have records of termite activity for each area and may be able to advise on whether termite risk management is needed. If you are building in those jurisdictions, that note is the first thing to check rather than the last.

What a compliant system must include

The Part sets out the requirements directly. Where a termite management system is required it must be selected appropriate to the table, comply with AS 3660.1 or have been tested and passed the tests required by Section 5 of AS 3660.3, have a durable notice installed, and include additional measures in areas where Mastotermes darwiniensis are prevalent. Where a chemical system is used, the chemical must be included on the appropriate authority's pesticides register.

Queensland inserts a further requirement into the same clause: the system must have a design life of at least 50 years for a non-temporary Class 1 building, or for other buildings a design life of at least 50 years or the specified design life of the building, whichever is the lesser, with an exemption where the system is easily and readily accessible for replenishment or replacement.

Read the design-life requirement against your exit. A system with a stated design life and an inspection regime is an asset you can document and hand over. A system nobody can find on the plans is an unfunded liability for whoever owns the building next.

The checks a student would run, in order

1. Confirm with the certifier whether the site is in an area of known termite risk and whether any susceptibility applies to the design.
2. Have the installer nominate the system before the slab is poured, in writing, with the AS reference.
3. Photograph the installation before it is covered, and file the photographs with the compliance documents.
4. Confirm where the durable notice will be fixed, and what it must record.
5. Include the system, its installer, its warranty and its maintenance regime in the handover pack.
6. Check the footing and ground conditions at the same time, because termite systems are installed into ground that must itself be classified.

The trap

Treating termite protection as a product decision made on site. It is a documented compliance requirement with a lifecycle, and the documentation is part of the deliverable. The second trap is assuming the same requirement applies everywhere: the explanatory note about Tasmania and parts of Victoria, and the Queensland design-life variation, are the same clause read differently depending on where you build. Copying a specification from another state without checking the schedule is how a project ends up paying for a system it did not need, or missing one it did.

What it means for feasibility

Carry termite management as its own construction line item, not inside a general allowance, and carry the handover obligation with it: the notice, the certificate, the installer's documentation and the maintenance schedule. Then check the companion ground conditions, because the Housing Provisions require foundations to be classified in accordance with AS 2870, and a site classified H, E or P requires reference to AS 2870 for design and construction. The same site-preparation section that governs your slab governs your barrier.

You are not expected to solve this yourself. The correct next step is to engage a licensed pest management technician or the system installer to nominate the system, with your building certifier confirming the applicable edition and state variation for this building. Ask them to confirm whether the area carries a known risk, how the system satisfies AS 3660.1, where the durable notice will be fixed, and what the owner must do to maintain it. They do the technical assessment. You carry the document into the handover pack.
