Rafferty’s have successfully completed structural repair works to a 73.2m high steel chimney in the Northern Ireland.
A re-design and feasibility study of the structure was initially carried out which revealed that structural modifications and repairs were required to ensure the structural integrity of the chimney. This involved installing stiffening steelwork between the 20m and 24m level along with removing the existing helical strake wind stabilers and replacing them with a liquid filled stabilising damper system.
A team of 3 steeplejacks and welder platers successfully completed the project to the complete satisfaction of the client and without any disruption to the operating conditions of the chimney.
The following photographs outline the works carried out.
