For NZTA & Government
A senior-led IDM panel partner delivering audit-defensible work at programme scale
NZTA and central-government work demands process discipline, traceable evidence and people who can carry a programme without close supervision. The standards are exacting and the audit trail matters as much as the outcome.
TTAP holds NZTA IDM Professional Services panel appointments for Pavement and Surfacing Design and for MSQA, and brings senior practitioners across modelling, economics, business cases and intelligent transport systems. We work the way the Transport Agency expects — senior-led, digitally evidenced, real-time reporting, audit-defensible.
