Business is still booming for ENR’s Top 600 Specialty Contractors following a third consecutive year of double-digit revenue growth despite strained labor pools, rising construction costs and shifting sector demands. Firms revealed in comments that their greatest measure of success is the ability to invest in their employees.

As much as construction technology has improved workplace efficiency, speed of information and reporting in a short period of time for many Top 600 firms, construction is still a “nuts and bolts” business “where we are constructing a building one piece and one screw at a time,” says Michael Dominici, executive vice president of the Circle Group.
