Coastal Hazards 

We regularly work on coastal hazard assessments for development projects around our shoreline including assessment of erosion and inundation risk. 

For sites struggling with erosion we have engineered various sea defence structures, starting from engineering investigation and design, assistance with consent through to managing contracts for completion of the physical works. 

Jetties Board Walks and Boat Ramps 

Haigh Workman has completed engineering investigation, structure design and detailed drawings for many private jetties throughout Northland. Our sought after coastal setting sees us working with clients wanting to develop more simplistic structures through to high quality exotic hardwood structures. 

Marina Structures

Haigh Workman are proud to be involved in the New Zealand Marina 

Industry and this specialisation has seen us design marina structures, pontoons and piles around various parts of New Zealand and the Pacific Islands.
