Since its inauguration in the 1960s, every year more than 10 million tourists visit the Hollywood Walk of Fame in hopes of experiencing the glitz and glamour of Los Angeles’ most famous attraction. To this day, its 18 blocks of terrazzo floors remain in a good state, revealing the longevity and durability of a material able to withstand heavy foot traffic over the course of the century.

Comparing revenues from the previous year, Architectural Record lines up annually a list of the Top 300 U.S. Firms. Based on the 2019 data, Gensler tops again the selection, for the ninth year in a row, and Perkins and Will takes the second position. Third, fourth and fifth places were presented for Engineering Architecture firms HDR, Jacobs, and AECOM. Other companies in the top 10 include HKS and Skidmore, Owings & Merrill.
