From graduation to 1967, he lived in Sudbury, Ontario, working for eighteen years at Inco mines, smelters and refineries and specializing in industrial safety and rock mechanics.
To meet this need, Kierans used proven Dutch and Californian experience to design his Great Recycling and Northern Development Canal concept in the 1950s.
However, despite Quebec’s past Premier Bourassa’s and prominent engineering groups’ endorsement of detailed study of his concept, as well as an invitation to outline it to the American Society of Civil Engineers in 2001, some Canadian authorities unfortunately fail to understand basic differences between run-off recycling as opposed to potentially harmful headwater diversions or simply fear any joint water management with the US.
While at MUN he worked with Newfoundland and Labrador Hydro on the 1975 attempt at a hydropower only crossing of the Strait of Belle Isle,[1] chaired the Environmental Committee on Brinco’s Kitts-Michelin uranium project, and was on the Editorial Board of the American Society Of Civil Engineers’ Manual on Nuclear Structures And Materials.
In 1983, he founded Deltaport Limited to create a very large, mid-ocean, floating, sea and air base using tetrahedral space frames.
In his later years he wrote three websites that reflected his interest in large-scale joint North American water management, floating mid-ocean sea-air bases, and the proposed Newfoundland-Labrador fixed link.
