CAL stands for Contractor Accreditation Limited — a not-for-profit, 100% Territory-owned organisation established in 1995 by the NT Chamber of Commerce, Territory Construction Association, and the Small Business Association of the NT. Since then, CAL has been the recognised body for accrediting builders and contractors working across the Territory.

It's not just a certificate — accreditation is a demonstration that a builder has the financial capacity, track record, and systems in place to manage projects responsibly, at scale.

CAL accreditation is the preferred pre-qualification for contractors seeking work above $100,000 in the NT, and the majority of Northern Territory Government work requires it. Accreditation ratings range from $50,000 up to more than $50 million, depending on a builder's proven capability.

MPH Projects is accredited up to $15 million — placing us in the bracket trusted to deliver major commercial and government projects across Central Australia.

Why it matters for clients
Choosing an accredited builder isn't just about ticking a box on a procurement checklist. It's about risk management.

A CAL-accredited builder has demonstrated they can manage complex projects — procurement, subcontractors, safety systems, financial controls — at the level their rating allows. When something unexpected happens on a large project (and it always does), you want a builder who has the systems and experience to manage it without the wheels falling off.

For government and institutional clients, accreditation is often a mandatory requirement. But for private clients too, it's worth asking about before you sign anything.

Our track record

With over two decades of experience, MPH has delivered major projects across Alice Springs, Tennant Creek and Yulara — spanning education, recreation, commercial, accommodation, health and civil works.

Our accreditation isn't just a credential. It reflects how we actually work: rigorous planning, transparent communication with clients, and a genuine commitment to delivering what we say we're going to deliver.
