What Lerch Bates does

Lerch Bates is a global technical consulting firm providing building performance services across the full lifecycle of structures, from design and construction through management, investigation, and repair/modernization. The company organizes its offering under a Total Building Performance framework that integrates two core specializations: Building Science (envelope, facade, waterproofing, testing, forensics, and enclosure commissioning) and Building Flow (vertical transportation, pedestrian circulation, parking consulting, and building logistics), supported by specialized service modules including Vertical Transportation, Building Enclosures, Building Logistics, Parking Consulting, Pedestrian Circulation, Forensics, Facade Access, Testing & Commissions, and the LB Solutions lifecycle asset management program.

The underlying technology is domain expertise delivered through senior consulting staff averaging 25+ years of industry experience, codified into methodologies, documented across 386 reference projects in 50 countries, and protected as intellectual property in trademarked programs such as Total Building Performance and LB Solutions. Headquartered in Denver, Colorado with roughly 28 disclosed offices across the United States plus the United Kingdom, India, and Turkey, and 100% employee-owned through an ESOP, the firm has expanded capabilities via four acquisitions since 2019 (Pie Consulting & Engineering, AXIS Facades USA, Studio NYL, and BECS Technology).

Revenue is generated on a project-based professional services model, with fees structured as hourly consulting engagements, fixed-price project work, and multi-year retainer arrangements, sold through a sales-led, relationship-based go-to-market motion targeting architects, general contractors, developers, institutional owners, and risk managers.
