Rounding out the top five were Omaha, Nebraska-based Kiewit and New York City-based STO Building Group, at No. 4 and No. 5 respectively. Each dropped a rank from the previous year as MasTec’s entrance shuffled the list.
Of last year’s top 10, nine firms remained. Irving, Texas-based Fluor dropped three spots, from No. 5 to No. 8, as Baltimore-based Whiting-Turner and Redwood City, California-based DPR moved into the No. 6 and No. 7 spots, respectively. The only absence in the top 10 was Dallas-based AECOM, which fell to the No. 14 slot from No. 10 last year.
