The ENR California 2024 Best Projects Competition recognizes a number of projects with dynamic and innovative construction and design methods. This year’s entries featured ambitious green energy projects, major transport improvements and a range of impressive building renovations and improvements.
ENR California’s top projects are divided into two regions, Northern California and Southern California (which includes Hawaii). In this year’s competition, nearly 100 projects were submitted for judging. An independent jury selected 57 of them for recognition: 30 best projects and 27 awards of merit.
Judges from all corners of the AEC community spent weeks reviewing entries to reach five areas: project challenges and solutions, safety programs, innovative design and construction solutions, contribution to the construction industry and community, and like the quality and craftsmanship of the design. Projects were not eligible for an award if they had a construction-related death.

Judicial judges
Entries from each California region (North and South) were evaluated by separate panels of judges. Over the course of a month, the entries were independently reviewed, scored according to specific criteria, and then discussed in a virtual meeting with other judges to finalize the Best Projects, Merit Awards and Projects of the Year selections. Judges were asked to recuse themselves in cases of conflict of interest.

Excellence in Safety and Sustainability
This year’s competition also includes two special awards for each region of California: Excellence in Safety, which has been part of the competition for more than a decade, and Excellence in Sustainability, which is in its third year. The judges recognized two safety winners and five sustainability winners between the two regions.
The two special sustainability and safety awards for the two California regions were judged by separate independent panels.

Sustainability judges were Erin McConahey, Director, Arup, and Celia Hoag, Sustainability Lead, Southwest, DPR Construction.

In addition to selecting the category winners, the main competition judges also chose three projects from each California region to be considered as Project of the Year, the highest honor in the regional competition.
For Northern California, the finalists were Sonoma Academy Community Performing Arts Center (Best Project for K-12 Education) and St. Clare at Capitol Park (Best Project for Renovation/Restoration). Northern California Project of the Year honors went to 200 Park (Best Office/Retail/Mixed-Use Project).
For Southern California, the finalists for Project of the Year were the I-405 Improvement Project (Best Road/Bridge Project) and Tarzana Reimagined (Best Health Care Project). Southern California Project of the Year honors went to the Delta Sky Way program at LAX (Best Airport/Transit Project).
