Each year, ENR Southwest ranks the largest projects to start construction during the previous year in the states of Arizona, Nevada and New Mexico.

As ENR Southwest correspondent David Brown recently reported, large manufacturing projects have become a driving force in the region, with new contract announcements a regular occurrence the last several years. Those include Intel’s $20-billion Fab 52 and 62 semiconductor plants, scheduled to open in Chandler, Ariz., in 2024, and the $12-billion TSMC semiconductor factory in north Phoenix, also anticipated for 2024.

And while those projects are now closer to completion, the manufacturing sector is still generating additional new "starts," as represented in the preliminary "preview" version of the yet-to-be finalized Southwest Top Starts ranking.

ENR Southwest uses a variety of sources, including information from Dodge Data & Analytics, as well as news reports from Engineering News-Record and other media publications. If your firm started construction on a major project of $100 million or more during 2022, it's not too late to let us know so we can possibly add it to this year's Top Starts ranking.
