About Us

Welcome Our New Professional Geologist – David Walker

We are excited to welcome a new member of our professional staff – David Walker. As a licensed professional geologist (NH) with experience in hydrogeology, he will conduct Phase I & II Environmental Site Assessments, groundwater monitoring and remediation, and aquifer analyses.
His twenty years of experience includes monitoring groundwater contaminant plume migration and remediation at multiple industrial and commercial sites, Brownfield assessment and remediation, Storm Water management, RCRA and CERCLA remediation projects, and federal and state environmental permitting.
Dave will also assist the geotechnical group with geotechnical evaluations, subsurface exploration and sampling, geophysical testing and seismic studies.

David is an avid cyclist, skier and hiker. He’s climbed most of the 4,000 foot mountains in Maine and several in New Hampshire, but lately his adventures are more geared to sports with his nine year old son. He’ll be working on projects in both Maine and New Hampshire, from our Saco office; if you’re in the area, stop by and say hello.

Groundbreaking for Patrons Oxford Insurance Company

April 27th was the official groundbreaking for Patrons Oxford Insurance Company in the Portland Technology Park, Portland, Maine. We’ve been proud to be a part of the design/construction team with Scott Simons Architects, Becker Structural Engineering, and Zachau Construction on this project. Our role is geotechnical engineering, special inspections and materials testing. Over 300 yards of low density cellular concrete has been placed so far. The light weight concrete is used to reduce building settlements as an alternative to a more costly pile foundation.
