The townhouse at 107 West Saratoga St. in downtown Baltimore looks much the same as it did in 1923, when it was the first address of a structural engineering consulting firm that eventually would become known as RK&K. Just as that edifice has endured throughout the decades, the nascent enterprise it housed has grown and evolved into one of the top transportation and infrastructure consultants in ENR’s MidAtlantic region.
This year, RK&K marks its centennial and has nearly 1,000 employees in 18 MidAtlantic offices. It also has become an important player in a variety of major projects across the region. Ranked at No. 5 on the 2023 ENR MidAtlantic Top Design Firms list, RK&K recorded $214.7 million in regional revenue in 2022, up nearly 14% from 2021, when the firm ranked No. 7. Its national revenue total of $302 million for last year placed it at No. 76 among ENR’s 2023 Top 500 Design Firms.
