The original March 11 deadline for ENR California’s annual Top Design Firms survey is long past, but we’re still keeping the survey open for a few more days. With that in mind, we encourage any architectural and engineering firms doing business in California and Hawaii to take part by clicking here to start taking the survey.

Here, we've updated our original preview of the 80-plus design firms that have thus far submitted a survey. By comparison, last year ENR California included 95 firms in its final Top Design Firms ranking. Also, ENR California will soon be reviewing information submitted by this year’s survey participants for potential Design Firm of the Year candidates.

The California Top Design Firms ranking will appear in the May 27 print edition of ENR California. An important note, however: Because of space limitations, it’s possible that firms listed here may not be included in the print ranking as a result of their revenue totals.
