Now in its third year, ENR California's Top 20 Under 40 list makes clear that the construction industry has a deep well of talent. Our 2013 competition drew a record number of entries, with nominations submitted for young professionals in all facets of design and construction. The unprecedented response is a hopeful sign that the industry in California has a full roster of emerging leaders.

Our Top 20 Under 40 list, selected by an independent jury, includes up-and-coming employees and those who already have lead roles in their respective firms.

The jury selected winners on the basis of candidates' career experience; industry leadership; community service; and other factors. This year's jury included Pauly De Bartolo, designer at De Bartolo + Rimanic Design Studio, San Diego; Marylou Flanders, pursuits manager, water & environment, at Atkins, San Diego; Leah Hislop, online communications and marketing specialist at Arup, San Francisco; and Gary Miller, vice president of transportation at RBF Consulting, Irvine.
