We lifted two atrium roof structures to their final position on top of the college. Each roof light comprised a steel work structure and aluminium curtain wall, measured 10 metres squared and weighed approximately 11,000kg.
The roof lights were constructed on the ground floor level and were lifted to the roof using specially designed temporary bracing and a 250-tonne crane. This was a major lift that we were pleased to see take place so smoothly.
What now remains is to glaze the structure. Our main works there are due to be completed in October, with demobilisation of site and access to be completed by November.
