Company History
Our story began in 1977 with our first consulting QS office opening in Invercargill.
New Zealand
The practice was restructured and expanded nationally. Martin Quartermaine and Patrick Hanlon joined in 1993 and 1994 respectively.
In 1996 Patrick transferred to an associated multi-national firm in Sydney while the practice continued to grow locally.
The practice became part of a multinational with offi ces in 20 countries and over 400 professional quantity surveyors. Local members gained international experience.
Our international partner exited as they were acquired by a PLC. BQH was chosen as our new brand, underscoring continuity, tradition and accessibility.
