ENR California’s April issue will feature a ranking of the biggest projects to break ground during 2015. The list will include 25 (or more) of California's largest starts. 

These top construction starts total tens of billions of dollars in construction activity for California and Hawaii. All of these projects are valued at more than $150 million. 

The project starts are listed alphabetically below. Be sure to read the April edition of ENR California to learn where each of these projects rank, and to find out additional information such as construction costs and project teams. The Top Starts section will also feature interviews with key members from some of the project teams.

The following list is preliminary, and is subject to change as additional information becomes available prior to publication of the ranking. Think we've missed a project over $150 million that began construction in 2014? Please let us know in the comments field below. Note a project start is defined as the beginning of construction activity on the job site, as opposed to just the start of pre-construction or a formal ground-breaking ceremony.
