Our Story
Our Story
The original Gibbons Contractors Ltd, a civil engineering and precast business, was founded by Colin and Dick Gibbons in 1969. In 2007, Gibbons Contractors Ltd was acquired by the four current directors: Ron Williams, Graham Dowd, Mike Harris, and Chris Lobb. The company then operated alongside Harris Dowd Construction Ltd, one of Auckland’s leading specialist concrete and formwork subcontractors, which had been established in 1998 and was owned by Graham and Mike.
In 2019, the two businesses were merged and rebranded as Harris Dowd Gibbons Construction Ltd (HDG).
