PROJECT HIGHLIGHTS 2022 2023

From an energy-efficient ice arena project in Prince George to a hydroelectric dam project in Colombia, BC's engineers and geoscientists have displayed innovation and environmental stewardship in their work over the past year. Innovation 's annual Project Highlights edition showcases the many and varied recent projects of Engineers and Geoscientists BC registrants.

WUIKINUXV DEBRIS WALL AND WHARF FACILITY RECONSTRUCTION The Wuikinuxv Nation is heavily reliant on its wharf facility in Wuikinuxv Village, on the north bank of the Waanukv River. The wharf was severely damaged by large seasonal debris flows, which have worsened in recent years due to climate change. Westmar Advisors led a team that included Hatfield, EXP, DHI, and David Nairne & Associates to develop, design, lead community consultation, and obtain environmental permitting for an improved wharf facility protected by an innovative debris barrier. The new barrier is almost 100-m long and is supported by steel pipe piles up to 23.5-m long, driven up to 12 m into the riverbed. The barrier features fish passage and low environmental impact while offering improved safety, durability, and performance. Owner: Wuikinuxv Nation Participants: Westmar Advisors: Daniel Leonard, P.Eng., Jason Braun, P.Eng., Hong Liang, P.Eng.; David Nairne & Associates: Neil Courtney, P.Eng.; EXP: Ujjal Chakraborty, P.Eng.; DHI: Danker Kolijn, P.Eng.
