Procurement
NZTA-certified procurement specialist support across construction, ITS, professional services and asset-management contracts. Procurement plans, tender development and evaluation, contract compilation, and supplier coordination aligned to NZS 3910, NZS 3917 and AoG frameworks.
Who it's for
- NZTA Waka Kotahi
- Local councils

The problem we solve
Procurement is where a programme's value is won or lost. A weak procurement plan, a thin engineer's estimate, or a tender that doesn't evaluate what actually matters leaves a council exposed on price, quality and probity — and hard to defend if the award is challenged.
TTAP provides NZTA-certified procurement support end to end: the strategy and plan, a defensible engineer's estimate, tender documentation, evaluation and award — run as a clean, probity-managed process.

Who leads this work
Frequently asked
Are you an NZTA-qualified procurement specialist?
Yes — both Bob Hu and Jen Wen Gan are NZTA-qualified procurement specialists who hold NZQA Level 6 Procurement certificates, and we provide certified procurement support across construction, ITS, professional-services and asset-management contracts. The process meets NZTA's procurement requirements.
Can you prepare the engineer's estimate as well as run the tender?
Yes. A defensible engineer's estimate underpins the whole procurement — it sets the budget expectation and is the benchmark tenders are tested against — so we prepare it alongside the tender documentation.
How do you keep the evaluation defensible?
A transparent weighted-attribute evaluation against pre-agreed criteria, with probity managed throughout and the rationale documented — so the award stands up if it's ever questioned.
