This project included the construction of approximately 88 miles of 200 kV HVDC overhead transmission line in the province of Newfoundland & Labrador and approximately 28 miles of 200 kV HVDC overhead transmission line in the province of Nova Scotia. The project scope of work included environmental permitting, access trail construction, foundation installations, lattice steel tower assembly and erection, conductor, OHSW and OPGW installation and all related activities.
- Access trail construction over high-risk wetlands where the extensive use of geotextiles, wood matting and ﬁll materials were required to facilitate the safety passage of equipment and personnel.
- The entire Newfoundland alignment parallels the Trans-Canada Highway and required a detailed traﬃc management plan to be developed for worker and public safety as the large majority access points from the right of way exit onto the highway. This resulted in the establishment of a daily traﬃc management coordination process to facilitate the eﬀective deployment of multiple traﬃc management teams to ensuring zero disruption to traﬃc.
- Compressed construction window required work execution on three separate segments simultaneously in Newfoundland to achieve project milestones. This requirement made it necessary to mobilize over 250 personnel in one month with a peak workforce of over 300 personnel on site.
