Rafferty’s have successfully completed structural modifications and repairs on a 37m high steel chimney for a valued client in the North West of England.
A re-design and feasibility study of the structure was initially carried out which revealed that modifications and repairs were required to ensure the structural integrity of the chimney. The modifications included removing the existing helical strake wind stabilisers and replacing them with a liquid filled stabilising damper system. Steel stiffening work was also carried out to an area of the chimney shell below roof level. Repair works included replacing areas of the internal gunite lining which had previously failed. A team of steeplejacks and welder platers successfully completed the project to the complete satisfaction of the client.
