As we travel along highways, bridges, and overpasses, we often take for granted the strength and durability of the structures that support us. However, behind every solid construction lies a meticulous process of engineering and quality control to ensure that they meet the rigorous demands of public works.
Recently, South-East Scanning was tasked with a unique challenge by Enco Precast Pty Ltd, one of the largest producers of precast beams in Australia. The project involved conducting a series of Ground Penetrating Radar (GPR) scans on a pre-cast T-Girder beam in Brisbane.
The objective was to determine the concrete cover of voids within the T-girder. Voids can occur in concrete structures due to a variety of reasons, such as improper pouring, compaction, or curing. These voids can compromise the structural integrity of the construction and lead to potential failure or collapse. Therefore, it’s imperative to ensure that the voids are consistent throughout the T-Girder, and the reinforcement is in place to provide the necessary strength and support. The client required concrete cover of exactly 120mm with a tolerance of 5mm for the girder beam to be structurally sound.
GPR technology uses high-frequency radio waves to penetrate and image the subsurface of a material. In this case, the GPR was used to scan the entire length of the T-Girder beam from both sides. The results provided a clear image of the internal structure of the concrete, indicating the exact location and size of the voids. By using the GPR, the engineers were able to verify that the voids were consistent throughout the T-Girder and met the rigorous demands of engineering standards for public works.
The use of GPR technology has revolutionised the way engineering and quality control teams operate. GPR allows for a non-destructive and non-intrusive means of assessing the structural integrity of concrete structures. It provides a quick and efficient means of identifying potential issues, which can then be addressed before they become major problems.

In this case, Enco Precast Pty Ltd. was able to meet their contractual obligations by delivering a pre-cast T-Girder that meets the highest standards of quality and structural integrity. The use of GPR technology allowed for a detailed and accurate assessment of the internal structure of the T-Girder, ensuring that the voids were consistent and met the necessary requirements for public works.
The successful completion of this project is a testament to the importance of quality control in construction projects. By utilizing cutting-edge technology such as GPR, engineering teams can confidently deliver durable and reliable structures that meet the highest standards of quality and safety.
