Clear Line were appointed to complete the replacement of four glass units which make up part of the unitised façade.
We removed the failed glazing components and installed new structurally bonded units on four different levels of the north and south elevations. The supply of the units proved quite difficult as the previous supplier was outside the EU and were not contactable, therefore Clear Line was required to find the best match possible to existing materials.
The replacement units were pressure fixed, utilising an internal and external pressure plate and tourniquet system to the structural silicone which required 21 days to cure. A return visit was then made to ensure the units were fully bonded and to remove the internal and external pressure fixings.
As the replacements being completed were high rise we used the insitu BMU cradle and auxiliary hoist. A four in line woods vacuum lifter was used to manoeuvre the pieces of glass into place along with the hoist.
All operatives working on site were trained for working at heights and all received full BMU and hoist training.
