What TIAB does
TIAB S.A. is a Romanian technical systems integrator that delivers turnkey electrical, HVAC, plumbing, and industrial automation installations for industrial, infrastructure, and tertiary-industrial clients. Founded in 1949 and headquartered in Bucharest, the company operates as a wholly-owned subsidiary of the French group VINCI Energies, having joined that network in 2007. Following its 1993 privatization and subsequent acquisition, TIAB has been organized into a network of 14-15 business units — including TIAB-branded regional branches (e.g., Bucharest, Ploiesti, Braila, Constanta, Craiova, Timisoara, Pitesti, Slatina, Piatra Neamt) and ACTEMIUM-branded specialized units focused on electrical services, maintenance, and oil-and-gas work — enabling local execution paired with group-level expertise.
The company's technical portfolio is anchored on four core offerings: electrical installations across low, medium, and high voltage; HVAC systems with integrated energy recovery; industrial automation including SCADA/DCS, electrical and automation panels, and process control; and BIM-enabled 3D design plus 3D scanning for project optimization and maintenance. Service scope spans the full lifecycle — design, execution, commissioning, and preventive/predictive/corrective maintenance. Verticals served span automotive, oil and gas, petrochemical, steelmaking/metallurgy, food processing, logistics centers, office buildings, and shopping centers. Notable executed work includes 40+ years of Bucharest metro electrical substation modernization and 120+ MW of installed renewable energy capacity, with the broader historical portfolio reportedly exceeding 56,000 completed projects.
TIAB's revenue model is project-based B2B professional services, with revenue generated through turnkey project delivery, ongoing maintenance contracts, and design/execution services priced per project. Distribution is exclusively direct, operating through local business units across Romania, supplemented by corporate marketing via its multilingual website and LinkedIn presence. The firm maintains an unusually broad compliance posture — ISO 9001, ISO 14001, ISO 45001, SA 8000, ISO/IEC 17025, and GDPR — and operates the VINCI Energies Romania Academy for workforce training. Revenue, headcount growth rate, and ownership valuation are not publicly disclosed.
