Equipped with a smartphone application, inSPEC enables site engineers and supervisors to rapidly conduct non-destructive testing and inspection of RCC structures. inSPEC is ideal for a variety of structural analysis applications: repairs, renovations, inspections and quality control of RCC structures.<\/p>\n\n\n\n<p>inSPEC 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 inSPEC.
