Copper clad domes are found on many high status buildings, especially those dating from the early 20th century. Its high tensile strength, low weight, low expansion rate and chemical resistance make it especially suitable for domes and steeply pitched roofs.
We are working with Wilson Steeplejacks to investigate the condition of this dome in Belfast City Centre and spent a useful morning last week at high level looking at the condition of the copper and its support structure. Over time, the detailing of copper domes changed and this one has particular characteristics peculiar to its age of construction. Understanding the details for the age of the dome allows conclusions to be provided to the owners so that repairs can be managed. In this case, safe high level access equipment allows us to survey in detail and to actually touch the materials so that we can fully assess condition.
