David joined C3 in 2019 as his first job out of college. Since joining our team, he has worked to expand his knowledge in the areas of mechanical design, CAD programs and accurate hand-drawn field as-builts. David has gained valuable hands-on field experience firmly backed up by the collective knowledge of the C3 team. Working closely with clients, building engineers and architects, his responsibilities are wide-ranging, from verifying existing conditions and applying as-built conditions into AutoCAD to calculating heating and cooling loads and redesigning mechanical systems to effectively condition the space while maintaining code compliance.
