Marc’s engineering experience has included design and analysis of concrete and flexible pavements for public and private projects.  He has been involved with the study and repair of numerous landslides over the last 20 years.  These slide repairs have varied in complexity from simply revegetating “skin” slides to constructing fill buttresses and tied-back soldier pile walls to stabilize deeper unstable ground.  

Marc has lived, gone to school, and worked in the Pacific Northwest all of his life.  Some people may think it's crazy, but he loves the climate and scenery of this part of the United States.  Marc likes to sing, play the electric bass, and ride a tandem bicycle with his wife.  Make sure not to ask him about his passion for the sport of rowing, unless you have a fair amount of spare time. 

As Rob's work experience increased throughout his career, so has his direct interfacing with clients, design teams, and municipality personnel.  He is highly personable and respectful of the needs and concerns of all personnel involved in projects.  Rob believes that computers may solve analytical problems, but personal and direct contact with people still is the most important part of the job.  

“I work on well over 100 different jobs a year, so I have seen all sorts of different projects, construction styles, management styles, and municipality styles.  The most rewarding jobs for me have always been ones that posed geotechnical challenges, and the challenges were embraced by all of the design and construction team.  The result was a well-organized, profitable job for all.”   

Rob keeps busy chasing his young son, as well as mountain biking and skiing.  He also attempts the game of golf, but as he has found, analytical engineers make the worst golfers.  Although born and raised in Montana, he greatly enjoys the best the Pacific Northwest has to offer, from its beautiful lakes and mountains to its great wine.

James has been involved in projects ranging from single-family residences, multifamily developments, to office and commercial buildings.  He has performed preconstruction studies on a wide variety of projects and engaged in site inspections and project management during construction.  His professional design experience includes all aspects of geotechnical engineering, such as shallow and deep foundations; preload fills to induce preconsolidation of soft soils; roadways over soft soils; conventional and geotextile-reinforced retaining structures; dewatering and underslab drainage systems; and slide repair features including buttresses, soldier-pile walls, and crib walls.  James also has substantial experience with Geopier^tm reinforced soil foundation systems.  One of James’s mixed-use building projects on Mercer Island utilized over 1,000 Geopiers^tm beneath the foundations. 

“Most days this job is the greatest…we engineer and are allowed to get out from behind the desk, which is a huge plus to an old boy scout.  We help real people solve their problems face to face and are part of a team that gets to build solutions.”

James gets his kicks playing soccer and enjoys coaching youth soccer as a licensed Washington State Coach. He is an Eagle Scout and spent his youth backpacking the Sierra Nevadas.  James still loves to get his boots muddy.
