HWA became geotechnical engineer of record after acquiring Landau Associates’ geotechnical division in early 2024. The project required new foundations to support a 300% increase in structural weight and meet seismic standards. HWA analyzed liquefiable soils, advised flexible utility connections, and evaluated foundation alternatives—pipe piles, jet grout, and micropiles with anchors. The team continues providing inspections, including pile observation, load testing and vibration monitoring.

The Port of Bellingham planned to construct a larger, more robust heavy lift area by replacing a damaged/deteriorated segment of the Central Terminal wharf. HWA served as geotechnical engineer supporting design, conducting field explorations, laboratory testing and analysis, pile foundation and seismic analysis, and evaluated liquefaction hazards and lateral spreading risks. HWA also monitored the installation and testing of the new foundation piles during construction.

HWA performed a geotechnical investigation for the Pleasant Harbor Abutment Replacement Project at Pleasant Harbor State Park in Brinnon, WA. The project involved relocating the floating dock pier abutment upland, requiring evaluation of foundation options. HWA analyzed site conditions, recommending spread footings or drilled shafts based on dense glacial till and limited access. We provided design parameters, construction guidelines, and emphasized on-site monitoring to ensure stability and com
