PND was awarded the 2010 Project of the Year Award by the
Pile Driving Contractors Association in recognition of the
Skagway Harbor Surge Control Breakwater, in Skagway, Alaska.
PND used their innovative partially penetrating breakwater design to accommodate the unique site conditions, and to protect the Skagway Small Boat Harbor from southerly waves in waters up to 70 feet deep. The breakwater will now allow the Municipality to begin revitalization of their Small Boat Harbor, and the surrounding areas preparing for increased tourist activity in the region. PND provided planning, design, coastal engineering, permitting, bid assistance, and construction support for the new 290-foot-long breakwater, which was constructed in up to 70 feet of water (from mudline to high tide). Work included concept design and location and alignment of the breakwater, as well as structural and foundation design.
Additionally, PND’s coastal engineers prepared a preliminary wind and wave study for breakwater alternatives and also provided computer modeling. PND staff utilized both desktop and CGWAVE modeling of wave transmission, wave diffraction, and reflected waves to evaluate waves at the adjacent ferry terminal floating dock and the shoreline north of the planned wave barrier.
