Meeting Arctic Demands
PND Engineers tackles tough projects in the north By Mike Stimpson Innovation, adaptability and finding solutions for the challenges of building in Arctic and marine environments: PND Engineers has developed a solid reputation for all these things over the course of its 37-year history. That pattern of excellence continues as the U.S.-headquartered civil and structural engineering firm expands its reach in Canada's north through a Canadian subsidiary. A prime example of PND's innovation is the firm's proprietary (and award-winning) OPEN CELL® sheet pile technology, used over 200 times since PND Engineers developed it in the early 1980s for bridge abutments in Alaska's North Slope region. PND's website says OPEN CELL systems have “been used effectively in locations where other traditional bulkhead systems cannot work, including severe ice conditions, soft soils, exposed bedrock, deep water, high loading conditions, extensive scour and seismic events.”
