What Pie Consulting & Engineering does

Pie Consulting & Engineering is an engineering consulting firm specializing in forensic engineering and building sciences services, headquartered in Arvada, Colorado. According to the detailed operational data, the firm operates under a broader building and technical consultancy model that has been active for 75 years, organized around a 'Total Building Performance' framework covering five lifecycle stages: Design, Construct, Manage, Investigate, and Repair + Modernize. Core service lines include vertical transportation (elevator and escalator consulting), parking consulting, building flow and pedestrian circulation analysis, building science, testing and commissioning, building logistics, forensic engineering, building enclosures, and facade access design. The firm is employee-owned (ESOP) and operates through an employee-owner field network across 35+ global locations spanning the United States, United Kingdom, Belgium, Chile, China, India, and the Middle East, with flagship offices in major US metros and an international presence in Mumbai.

The firm generates revenue primarily through professional consulting services delivered via direct enterprise sales to architects, general contractors, developers and owners, institutional owners, portfolio managers, and risk managers. Services are delivered by technical consultants positioned across geographies, supporting both local and national client accounts. A proprietary platform, LB Solutions™, has been commercialized as a data-driven optimization offering — a 2026 case study documented six-figure client savings through elevator rope optimization — signaling a shift toward productized solutions alongside traditional advisory work. The firm is privately held with no disclosed parent company or institutional investor, and no funding rounds are reported. Most recently, the firm acquired Studio NYL (announced December 2025) to expand its building science capabilities into new markets.

Pricing is not publicly disclosed; engagements are initiated through direct consultation with technical experts via phone (e.g., 303-795-7956) or online inquiry forms. The firm maintains digital presence across a website, LinkedIn, X/Twitter, YouTube, and industry events, with localized content in Simplified Chinese, UK English, Chilean Spanish, Hindi, and Marathi to support international client engagement. No mobile applications, APIs, SDKs, or formal integration partnerships are disclosed, and the technology footprint remains centered on professional service delivery augmented by the LB Solutions™ optimization platform.
