Wiley|Wilson has once again appeared on Consulting-Specifying Engineer’s List of 2018 MEP Giants. This list ranks the top 100 engineering firms based on their mechanical, electrical, plumbing, and fire protection revenue.

According to CSE, the 2018 MEP Giants generated roughly $53.95 billion in gross revenue, an increase of about $6 billion over the previous year’s numbers. In just MEP revenue, the increase was still substantial, going from $6.33 billion to $7.64 billion.

The majority of companies on the list are private firms (60%). Coming in at a strong second, though, are employee-owned companies. They account for 26% of this year’s Giants.

CSE said that the 2018 MEP Giants earned the title by finding opportunity in the many changes in the building engineering industry. “The 100 firms selected as the 2018 MEP Giants continuously push the boundaries in the mechanical, electrical, plumbing, and fire protection engineering sectors, providing the top engineered systems in the building industry.”
