CAN was previously used to provide safety supervision to engineers in 2011. Indian/Norwegian joint venture Adjaristsqali Georgia LLC (AGL) contacted CAN to assist further with the inspection of a particularly inaccessible tunnel shaft.
The initial investigation by AGL had detected evidence of cracking within a 250m deep pressure relief shaft within their 37 kilometre long network of water-carrying tunnels, part of a huge multi-national hydroelectric project. AGL required experienced inspectors with a high level of rope access ‘know-how’ to safely access and inspect the shaft.
CAN Structures put together a uniquely experienced team of four level 3 operatives combining rope access skills, with many years of structural inspection, and extensive caving experience – including expedition and rescue. Conventional abseil techniques were used alongside powered (ActSafe) rope climbers. Detailed planning and complex rigging techniques meant IRATA protocol of ‘rigging for rescue’ was strictly adhered to at all times. As well as collecting empirical data and photographs, our inspectors also gathered video footage and commentary to give the client a better feel for the shaft conditions they were reporting on.
The material gathered proved to be highly valuable to AGL and fed into immediate actions taken on site, as well as informing future planning.
