The Maritime Link project involved the design, engineering, construction, commissioning, operations and maintenance of a new 500 MW (+/- 200 kV) HVdc (high-voltage direct current), plus a 230 kV HVac (high-voltage alternating current) transmission line.

Allnorth was retained to provide survey services for the Maritime Link Project. The scope of work included the boundary survey of more than 320 kilometres of transmission and grounding line corridor. In addition to this there was the boundary and topographic survey of 11 individual project sites, and approximately 40 kilometres of plan/profile survey of the grounding line, plus various smaller cable routes.

The survey and associated calculations were  challenging as much of the property had not been surveyed since the existing adjacent right of way had been established originally. The survey also included adjacent boundaries with numerous adjacent power line right of ways, private landowners, a provincial highway, major rivers, aggressive mountainous terrain and protected areas. 

The schedule was very aggressive, with initial fieldwork and preliminary plans provided to the client within two months of notice to proceed.
