What BTC does

Building Technology Consultants, Inc. (BTC) is an employee-owned professional consulting firm founded in 2001 and headquartered in Arlington Heights, Illinois. The firm specializes in forensic evaluation and repair design for building enclosure components, structural systems, and architectural elements — including roofing, waterproofing, parking garages, building facades, balconies, and historic preservation. BTC's diagnostic toolkit combines infrared thermography, concrete moisture testing, FAA-certified drone-based visual and infrared surveys, and 3-D rendering software used to convey construction defect findings in litigation settings. Since inception, BTC has completed over 1,200 projects spanning marquee assets such as the Wrigley Building, Northwestern University, the Citigroup Center, Motorola Headquarters, and FedExForum.

BTC monetizes its expertise through project-based professional services engagements covering eight core service lines (Forensic Investigation and Expert Testimony, Condition Evaluation, Specialized Diagnostic Testing, Repair Design, Bidding Assistance, Construction Phase Services, Design Assistance/Peer Review/BECx, and Transition/Capital Asset Studies) delivered across 13 vertical market segments including commercial properties, community associations, government/municipal, education, healthcare, hospitality, libraries, religious facilities, industrial, retail/entertainment, real estate development, and litigation support. Pricing is quote-based and project-specific; no public pricing tiers exist. The firm goes to market through direct client engagement, supported by a content-driven website, LinkedIn presence, industry-organization involvement (IIBEC, CAI-Illinois, BOMA, ALA), and earned media through publications such as Applicator Magazine. No intermediaries, resellers, or distribution partners are utilized; revenue mechanics are driven entirely by the firm's credentialed engineering bench and referral-based pipeline.
