Clark Pacific broke ground September 3 on a prefabricated building systems plant in Coolidge, Arizona that the company says will triple its total production capacity. The site runs 110 acres at completion, and manufacturing starts immediately in a temporary facility rather than waiting on the permanent build.
110 acres, phased, with production running through it
The plant goes up in phases with the final phase scheduled for spring 2027. Thirty manufacturing and engineering positions already exist on the site and the company expects to add another 70 by year-end, for 100 total. It joins Clark Pacific’s existing plants in Woodland and Adelanto, California, and extends the company’s service territory into the Southwest and Mountain West.
Coolidge sits in Pinal County on the I-10 corridor between Phoenix and Tucson, which is not an accident. That corridor feeds the Greater Phoenix data center and semiconductor fab construction pipeline, and the target markets Clark Pacific named are parking structures, data centers, advanced manufacturing facilities, and commercial and institutional work.
Precast capacity has been the quiet schedule risk
Structural precast lead times in the Southwest have been squeezing schedules for two years, and contractors have mostly solved it by absorbing the cost, redesigning around it, or in a few cases standing up their own shops. A manufacturer adding this much capacity is the supply-side answer to the same bottleneck.
The open question is where that capacity actually goes. Tripled output absorbed entirely by data center demand already in the queue does nothing for the parking structure or the mid-rise institutional job trying to book a slot. Watch Phoenix-area precast lead times through 2027 rather than the capacity number, because the capacity number is the input and the lead time is the result anyone is paid to care about.
The prefab argument, and the part that’s a claim
Clark Pacific frames the expansion around labor shortages, compressed schedules and rising construction costs pushing owners toward factory-built structural systems, and pitches prefab as delivering cost and schedule certainty against site-built structure. Donald Clark, the company’s co-CEO, was quoted alongside Christine Mackay of the Greater Phoenix Economic Council and Sandra Watson of the Arizona Commerce Authority.
Take the certainty claim as a vendor position, not measured data. Prefab shifts risk rather than eliminating it: the schedule certainty is real once the pieces are cast, and the exposure moves upstream into design freeze dates and shop drawing turnaround, which is where prefab jobs actually go wrong. Owners who haven’t run a heavy precast job underestimate how early the design has to be locked.
The labor argument holds up better than the cost one. The AGC and NCCER workforce survey released the same week put 87% of contractors with open craft positions and 42% reporting labor-driven project delays, which is the strongest case anyone can make for moving structural work into a controlled plant environment. Precast also shows up on the team sheets of jobs already leaning on it, including the Oak Ridge low-clinker cement work with Tindall Corporation, and on projects like Chicago’s Bally’s casino resort where a 3,300-space parking component sits inside a compressed downtown schedule.
