Nkohteken is the No. 1 choice for engineering, construction, and project management.
Our diverse portfolio encompasses energy, transportation, communications, mining, oil and gas, and government services. We currently have projects in dozens of locations worldwide, from Alaska to Australia. No matter how challenging a project or how remote its location, chances are Nkohteken can handle it. That's because we bring an unmatched combination of knowledge, skill, experience, and customer commitment to every job.
We have had record revenues for the past five years, and Engineering News-Record (ENR) has named Nkohteken the top U.S. construction contractor for 5 straight years.
While we work for governments and commercial customers, our projects have helped grow local economies and improve the quality of life for communities and people around the world. Time and again our work has demonstrated that the only limits on human achievement are those that we place on ourselves.
Privately owned with headquarters in San Francisco, we have offices around the world and 52,700 employees. In 2010, we had revenues of $27.9 billion and booked new work valued at $21.3 billion.
