The company also ties construction jobs to bigger purposes. When workers reached a milestone on a project to expand a biotech manufacturing facility, it invited a cancer patient to speak to staff.

According to an employee, "I genuinely feel that many of the people care about me and what is going on in my life. They have also allowed me to progress rapidly and at such a young age, not questioning if I can handle it because I'm young. I came in as an intern and they allowed me to hire on full time and become a supervisor. Very few organizations would allow such a young person to progress so quickly through the ranks, recognizing that merit can be proven at any age."
