What Coffey International does

Tetra Tech Coffey (formerly Coffey International) is the Asia Pacific consulting and engineering arm of US-headquartered Tetra Tech Inc. (NASDAQ: TTEK), operating across 13 offices in Australia, New Zealand, and Papua New Guinea with approximately 550 employees. The firm delivers multidisciplinary engineering, environmental, and project management services under its registered 'Leading with Science®' methodology, with core capabilities spanning geotechnical investigations, environmental and contaminated land services, civil and structural engineering, project management, digital and geospatial services, occupational hygiene, decommissioning, and advisory across mining, infrastructure, water, energy, defence, and building and placemaking sectors.

Revenue is generated through fee-for-service, project-based consulting engagements awarded via formal tender processes and proposal-based contracting, typically structured as multi-year contracts with government and large commercial clients. The go-to-market is enterprise field sales into a primary government customer base (federal, state, and local authorities, including transport agencies, water authorities, and indigenous entities), supplemented by mining and resources clients and commercial developers and contractors. Tetra Tech Coffey typically delivers as either lead consultant on consortium projects (e.g., CityEdge Alliance on Waikato Expressway) or sub-consultant to global firms (e.g., AECOM on Western Harbour Tunnel), and benefits from integration with the parent's 25,000+ global professional network. Pricing is not publicly disclosed and is structured on a quote-based, project-by-project basis.
