The $700-million Port of Anchorage expansion project is stalled in court, where the engineer says its design is not to blame.
PND Engineers Inc., a Seattle-based firm with offices in Alaska, designed the 135-acre expansion using the open-cell sheet-pile style to limit corrosion and persistent ice buildup on pile-supported docks. The design drives steel sheets into U-shaped cells, which are backfilled with earth and gravel to create new land.
