What 360 Engineering does
360 Engineering, Inc. is a privately held mechanical and plumbing engineering consulting firm headquartered in Golden, Colorado, founded in 2003 by Denise Dihle, PE. The firm operates as a B2B professional services practice serving architects, contractors, and building owners on new construction, additions, and renovation projects across Colorado and nationwide, with Professional Engineers licensed in 45+ states. Its three integrated service lines are Mechanical & Plumbing Engineering Services (HVAC and plumbing system design, load calculations, and construction support), Prime Engineering Consulting Services (multidisciplinary team leadership and project management), and Energy & Commissioning Services (energy audits, whole-building energy modeling, commissioning, retro-commissioning, and LEED documentation). Project delivery relies on industry-standard tools including AutoCAD, Revit, and Carrier HAP.
The firm is segmented by vertical across education (K-12 and higher education), government and civic (federal, state, and municipal including National Park Service), commercial (corporate offices, distribution centers, tenant improvements), recreation and culture (botanic gardens, theaters, visitor centers), science and technology (research laboratories and national-scale facilities), and historic preservation. Marquee clients include the National Park Service (multi-site), Denver Public Schools, University of Colorado Boulder, Denver International Airport, State of Colorado, National Laboratory of the Rockies, Crocs, OpenTable, and UPS, with work delivered either as prime consultant or as specialty MEP partner within larger architectural teams led by firms such as RATIO, DLR Group, HKS, Davis Partnership, Anderson Hallas, and Venture Architecture.
Revenue is generated through project-based professional services billed on fixed-fee or time-and-materials engagements with government agencies, educational institutions, commercial building owners, and nonprofits. The firm is structured around a six-partner leadership team and holds WOSB, WOB, DOT Certified DBE, Denver MWBE, and SBE certifications that provide preferential access to federal and municipal set-aside contracting. With approximately 20-25 employees, 360 Engineering competes on technical credentials (PE, LEED AP BD+C, ASHRAE HBDP/BEMP, CxA), complex existing-building expertise, and demonstrated delivery on historically and technically demanding public-sector projects.
