Why CAL Accreditation Matters
NT Government requires contractors undertaking eligible construction, civil and related services work above the relevant contract value to hold CAL accreditation.
CAL isn't just an application form. You need to demonstrate that your business has the financial capacity, technical experience and management systems to undertake work at the Rating and in the Sub-Groups you're applying for.
The application is the last step. The work is making sure the evidence behind it stands up.
Be Eligible
Meet the accreditation requirements for the NT Government work you want to pursue.
Prove Your Capability
Turn what your business has actually done into evidence CAL can assess.
Target the Right Level
Work out the Rating and Sub-Groups to target based on the work you want to pursue and what your business can actually prove.
Get Back to Running Your Business
We manage your application and keep it moving, so you don't spend hours navigating the requirements and chasing it yourself.
You'll know what you're paying, and why.
We know every business is different and CAL isn't one-size-fits-all. We take the time to understand your business before providing a quote so you're not paying for things you don't need.
You'll know what TERVELL will do, what you'll need to provide and what it will cost before you decide to go ahead.
No hourly surprises. No open-ended bill.
The TERVELL Guarantee
We can’t guarantee that CAL will accredit you or at what level, but we do guarantee the quality of our work. If CAL returns your application because of something we missed or presented incorrectly, we’ll fix it and resubmit it at no cost to you.
CAL accreditation is the first step towards competing for NT Government work.
Where CAL is required, accreditation gets you through the first gate. It doesn't win the tender. That comes down to the written response, scored against the published criteria and weightings by evaluators who may know nothing about your business beyond what you put in front of them.
That's the work we do next: tender strategy, written responses and the evidence to support them. And we help keep your accreditation current and at the appropriate level as the business grows.
Let's work out the right next step.
Book a call
Whether you're starting from scratch, upgrading your accreditation or not sure where to begin, we'll help you work out what's next.
The first step is simply a conversation.
Every enquiry is handled confidentially. We don't disclose who we act for or what opportunities they're pursuing without your authorisation.
