APEX Companies
Engineering and environmental consulting, with geotechnical work from a Portland office.
What they're known for
Geotechnical engineer on Gates Residence, a house set on a steep bluff above the Santiam River.
APEX Companies is an engineering and environmental consultant headquartered in Rockville, Maryland. The Portland office lists geotechnical engineering among its services: subsurface investigation, foundations, slope stability, and earthwork, alongside a wider environmental and infrastructure practice. Skylab credits the firm with geotechnical engineering at Gates Residence. The site makes that role matter. The house sits on a steep bluff above the river. A soils report for the project has not been published, so the foundation line that is public, conventional concrete, comes from the structural engineer, not from Apex.
