iPEC is a hand-held device for on-demand measurement of diameter and cover thickness of rebars in RCC structures. Equipped with a smartphone application, iPEC enables site engineers and supervisors to rapidly conduct non-destructive testing and inspection of RCC structures. iPEC is ideal for a variety of structural analysis applications: repairs, renovations, inspections and quality control of RCC structures.

iPEC started as a IMPRINT-2A project led by our group, with financial support from Science and Engineering Research Board (SERB), Government of India and Sanrachana Structural Strengthening Pvt. Ltd. Students and staff at the Wadhwani Electronics Lab (WEL) have significantly contributed to the development of iPEC.
