Founded in 1919, P1 Construction, LLC and P1 Service, LLC have grown into national construction and service providers with nearly 1,200 employees across seven offices. P1 is a specialty subcontractor providing HVAC, mechanical, electrical, plumbing, technologies, millwright, service, and architectural metal work in the Kansas City area and across the U.S. But there’s so much more to P1’s broad spectrum single-source capabilities, including value-added services like virtual design and construction, fabrication, and facility management and operations. Our staunch commitment to “safety first, quality always” has made P1 a trusted national partner for all things facilities.
