What constec engi,co. does
Constec Engi, Co. is a private Japanese engineering and construction company founded in 1969 and headquartered in Osaka. It is the core operating subsidiary in a six-company Constec Holdings Group; the five operating affiliates add environmental consulting, ground improvement and civil works, and bridge and civil-structure engineering to the group’s service chain. Constec Engi itself specializes in deterioration surveys and diagnosis of reinforced-concrete buildings, followed by repair, renovation, seismic diagnosis, reinforcement design, and construction; its remit also includes civil structures, asbestos removal, and dioxin decontamination. Its technical toolkit includes infrared, non-destructive, and micro-destruction inspection; finite element method and thermal analysis; the μVis seismic damper system; and the AG Bubble environmental-remediation system.
Revenue comes from project-based professional engineering and construction services, not a disclosed subscription product or standard price list. The company sells directly to public- and private-sector building owners, facility managers, infrastructure operators, civil contractors, and environmental-services customers; the wider group has offices across major Japanese regions. Pricing is not public, and the available information says fees are determined through individual project assessment and quotation.
