Objectives The primary deliverable will be a report demonstrating how effective the two approaches, vibration and ground penetrating radar are, both separately and in combination. In some respects, the approaches are complementary, and it is expected that they will reveal different aspects of the structure. If the effectiveness of the methods is demonstrated, further optional deliverables may be pursued: Software to facilitate the use of the techniques by non-experts. Training in the use of the techniques by non-experts. The project will be considered successful if the aforementioned objectives are realised.
Abstract The structures that make up our transmission overhead line network can be extended with good maintenance and strategic replacement of steelwork. It is easy to observe and identify the corrosion level of the bare steelwork on a lattice tower. However evaluating the condition of the tower steelwork and concrete when buried out of sight is very difficult. The current approach for evaluating the condition of existing tower foundations involves excavating around the foundations so they can be visually inspected. The excavation increases the complexity, cost and environmental impact of the inspection. The foundations are subject to targeted assessment during, or before major works; every tension and angle tower is assessed as well as a sample 20% of suspension tower foundations. Due to the intensive labour and time effort involved, it is normal practice to intrusively inspect only a sample of towers SPEN will provide validation and quantification of the potential benefits and provide guidance to Transmission Owners (TOs) and Distribution Network Operators (DNOs) for its implementation into Business as Usual (BaU). This will be achieved through the following methodology: 1. Technology Demonstration Impact Excitation Ground Penetrating Radar 2. Validation and Verification 3. Modal Analysis4.
