Construction of buildings and skyscrapers in Singapore, Malaysia and other Middle East and South Asian nations is one of the most difficult jobs for construction site engineers. They need to check every aspect starting from the ground level to the highest point of the building, ensuring that all the raw materials as well as the finished products used to create a building are of great quality, and the building will not fall down under any circumstances. Therefore, various testing techniques are used by construction site engineers to ensure the strength and durability of the materials used. As these methods of testing do not damage or destroy the core product in any way and also are cost effective, these testing and inspection methods are known as Nondestructive Testing or in short NDT.
Nowadays, advanced NDT inspection techniques are used by engineers in Singapore, Malaysia and other regions for testing the quality and durability of materials. This is a very safe technique and it also ensures that the materials are not damaged in any way. Nondestructive testing is performed to check the durability of the materials used and also find out whether there are any internal flaws like cracks or leaks present in the material without destroying them while inspecting.
Some of the commonly used NDT techniques for testing buildings and other constructions are:
- Rebound Hammer Testing
- Penetration and Pullout Testing
- Radiographic Testing
- Ultrasonic Testing
- Liquid Penetrant Testing
- Visual Testing
- Windsor Probe Testing
- Ground Penetrating Radar
In building and construction field, NDT is used not just when a new building is constructed, but also to test the integrity of materials present in existing constructions too, thereby preventing probable damages of the building as well as saving human lives. Therefore, it is well advised to perform regular inspections of buildings and constructions through nondestructive methods and repair the internal defects when they arise.
