Conducting Non Destructive test for Golden Photo Studio Building, Gracias Furtado Building I and II, Predio Cardozo Building and Villa Coutino Building in Margao in Margao constituency.

Rebound Hammer Test: Preparing the surface of RCC structural members such as beams,columns,slabs etc. by chipping off the plastered surface/finishing/clading to expose the concrete, and followed by smoothening the surface using carborundum stone in accordance with relevant IS codes. The task shall involve adequate manpower, technical personnel, and necessary tools. A rebound hammer test shall then be conducted as per IS 516 (Part 5/Section 4):2020 in the presence of GEC officials, with all readings properly recorded. Upon completion, the area shall be thoroughly cleaned

UPV(Ultrasonic Pulse Velocity) Test: Preparing the surface of RCC structural members such as beams,columns,slabs etc. by chipping off the plastered surface/finishing/clading to expose the concrete, and followed by smoothening the surface using carborundum stone in accordance with relevant IS codes. The task shall involve adequate manpower, technical personnel, and necessary tools and coupling agents . Carry out UPV(Ultra sonic pulse velocity test) in accordance with IS 516 Part-5 Section 1/2018 by portable ultrasonic non destructive test equipment test( Valid Calibration Certificate Required) in the presence of GEC officials, with all readings properly recorded. Upon completion, the area shall be thoroughly cleaned.

HALF CELL POTENTIOMETER TEST : Carry out half cell Potentiometer test as per IS 516 Part-5 Section 2/2018 After locating the reinforcement followed with preparing the surface of RCC structural members such as beams,columns,slabs etc. by chipping off the concrete surface/finishing/clading to expose the reinforcement and followed by cleaning the surface in accordance with relevant IS codes. The task shall involve adequate manpower, technical personnel, and necessary tools and chemicals in the presence of GEC officials, with all readings properly recorded. Upon completion, the area shall be thoroughly cleaned.

Carbonation test Carbonation Test in accordance with IS 516 Part-5 Section 3carbonation test to measure extent of carbonation from the concrete surface. The task shall involve adequate manpower, technical personnel, and necessary tools and chemicals in the presence of GEC officials, with all readings properly recorded. Upon completion, the area shall be thoroughly cleaned.

Core Test : Deciding the location by using scanning of the concrete surface using a reinforcement locator such as Hilti PS 300 or equivalent, to accurately identify embedded reinforcement and mark safe zones for core extraction. After confirmation, core cutting shall be carried out through RCC members (e.g., slab, beam, or wall) of the specified diameter using a diamond core cutting machine with water cooling, in such a manner as to minimize disturbance to reinforcement and maintain structural integrity. Concrete cores shall be finished, capped, and prepared on both faces in accordance with IS 516 (Part 1/Sec 1): 2018 and IS 1199: 2018 for compressive strength testing.Properly labeled and handed over to the GEC-approved laboratory for further testing and documentation.The void left after coring shall be reinstated using non-shrink, flowable micro-concrete or approved cementitious grout as per manufacturer specifications and IS 15388: 2003 (for grouting materials in structural concrete.)
