Arctic Transportation Solutions

Our expertise in arctic engineering covers many aspects of engineering, ranging from building and bridge design to site civil and geotechnical design. It also involves arctic hydrology studies, permafrost foundation design, as well as ice-structure interaction. PND routinely designs for severe environmental conditions, including heavy snowloads, both continuous and discontinuous permafrost conditions, and working in extreme temperatures. PND’s broad arctic experience has emphasized the importance of dealing with a host of critical issues, such as cold-temperature material fracture toughness, the effects of spring breakup on rivers for both flooding and bridge design, remote access utilizing ice roads and pads, and construction logistics associated with the Arctic.
