• Structural Assessment & Rehabilitation

    Service offered:

    UPV test of Concrete Structure for Quality Assessment
    • Health and condition assessment of concrete and masonry structures including fire damaged structures
    • Detailed investigations of structures like buildings, bridges, dams, power plant RCC structures, chimney, silos, overhead Tanks, etc., to figure out the root cause of distress and formulate effective strategies for repair & rehabilitation along with use of novel technologies like cathodic protection systems
    • Non-destructive evaluation techniques like Rebound Hammer Test, Ultrasonic Pulse Velocity test, concrete core extraction, half-cell potential measurement, Rebar detection & concrete cover depth measurement, carbonation depth measurement, Electrical Resistivity Test, air permeability test, crack width and crack depth measurement, etc
    • Use of supplementary tests for investigations such as chemical analysis (for evaluation of pH, chlorides, sulphates etc.) of hardened concrete samples collected from the site and other specialized tests such as Mercury Intrusion Porosimetry (MIP), Optical Microscopy (OM), Differential Thermal & Thermo-Gravimetric analysis (TG-DTA), X-Ray Diffraction (XRD) Analysis, etc., which are made use of in analysis from time to time.
    • Quality Inspection and Quality Assurance of ongoing repair & rehabilitation works
    • In-situ quality assessment and durability investigation of existing structures

    Studies undertaken

    Pile Integrity Test of Prestressed Concrete Bridge
    Condition Assessment of RCC Bridges

      In-situ testing of concrete structures for assessment of quality and condition assessment of concrete structures of various types across the country have been done. More than 25 sponsored projects have been completed in the year 2021-2022

      Condition assessment works completed during the year 2021-2022 include civil structures like multi-storey RCC buildings, load bearing masonry structures, RCC structures of Power Plants like RCC foundations of Turbine Generator, Boiler Mill Foundation, FD & ID Fan Foundations, Chimney Shells, Induced as well as Natural Draft Cooling Towers, RCC tower and reactor foundations of electrical substations, etc.

      Some of the major sponsored projects completed during the year 2021-2022 include:

    • Condition Assessment of RCC Township Building at NTPC Gadarwara
    • Condition Assessment of Residential Accommodation for NHAI
    • Condition Assessment of RCC Wall along the Conveyor Belt at NTPC-Bongaigaon
    • Condition Assessment of NDCT 1 & 2" at IGSPP Jharli
    • Condition Assessment of various Structures at NTPC SSTPS (Singrauli)
    • Concrete core extraction and testing for PSC poles of BSES
    • Condition Assessment of New Building of SSK Hospital (G+5) storied, New Delhi
    • Condition Assessment of RCC Tower & Reactor Foundations at Substation of PGCIL
    Core extraction from RCC foundation Half-cell Potential Measurement of Corrosion Damaged Structure Carbonation depth being measured on freshly extracted core at site
