Soldiers Pond Civil Earthworks
The Labrador-Island Transmission Link is a component of the Muskrat Falls project that involves the construction of 1,080 km of overland transmission lines from Muskrat Falls, Labrador to Soldiers Pond, near St. John's. The Soldiers Pond site will be used to convert the high-voltage direct current (HVDC) electricity used for long-distance transmission to alternating current (AC) electricity ready for market on the island of Newfoundland.
In 2013, HJO was awarded the civil earthworks portion of the Soldiers Pond substation project. The sope of work included site grading and associated work for the new substation, consisting of a 230 kV AC switchyard, a 350kV HVDC converter yard and a synchronous condenser facility. The major work items included clearing, grubbing, bog and muskeg removal, overburden excavation and fill placement, rock drill and blast, rock crushing and screening, design and construction of the main site access road, construction of temporary roads and laydown areas plus development of the borrow pit.
