What Alliant Systems does
Alliant Systems is a Pacific Northwest design-build mechanical contractor founded in 1999 in Beaverton, Oregon, and now headquartered in Portland. The firm delivers integrated HVAC, plumbing, piping, and building automation solutions through three tightly coupled lines of business: in-house engineering (mechanical systems design, BIM/VDC, design-build delivery), mechanical construction (equipment installation, piping, HVAC, commissioning, controls), and ongoing HVAC, plumbing, and controls service with 24/7 emergency response. Underlying technology centers on BIM/VDC for clash detection and coordinated virtual modeling, a dedicated building automation group using Distech and Innotech control platforms staffed by factory-trained technicians, and a Building Performance Services team that handles energy benchmarking, EUI calculations, and compliance navigation for Oregon BPS and Washington CBPS regulations.
Revenue is generated primarily through project-based mechanical construction contracts across healthcare (Salem Health, Providence, OHSU, PeaceHealth, St. Charles), higher education (University of Oregon, Oregon State University, Portland Community College), K-12, commercial office (AirBnB, Finastra), municipal government (City of Salem, TriMet, Oregon Military Department), food and beverage (Tillamook), and light-industrial customers. A secondary recurring revenue stream comes from HVAC and plumbing service agreements and building automation maintenance contracts, which provide a stabilizing tail on top of the lumpy project revenue. Sales are executed through direct field sales teams and account executives at four regional offices (Portland, Eugene, Bend, Seattle), supported by industry association engagement (ASHRAE, DBIA, ASPE, ACE Mentorship, NECA/IBEW) and a website with online service request portal. The company is privately held, has not raised institutional funding, and is led by long-tenured employees including President Josh Rozell (who started at age 14 in the warehouse) and CFO Renee McNannay (21+ years).
