Forming part of a larger development around Owen Street, Deansgate Square will be completed by 2020, and is set to be one of the most eye catching new developments on the city skyline – designed by award wining architects Simpson Haugh.
Over time, during the construction process, the glazed façade of each building has started to show signs of weathering and deterioration – due in part to the ongoing construction works. Renaker wanted to assess the methods used to clean, restore and sustainably protect the building façade in line with its predicted lifespan.
The previous approach to façade cleaning, care and maintenance is now not aligned with the building’s future performance and maintenance requirements. Whereas other suppliers had trialled other more abrasive testing methods, we took the time to understand the client’s required outcomes, providing a more holistic solution to deliver what was needed to improve the aesthetic finish, condition and building’s long term performance.
We were asked to undertake cleaning test trials to the lower, more heavily contaminated areas of the building. Making use of the crash deck scaffold, we undertook test sampling, varying the methods, product dwell times and application phases. Using non-abrasive pH-neutral products, approved by the glazing and seal manufacturers, we successfully removed the heavy build-up of concrete dust and contaminants that had adhered to the glazing surface.
Following the test trial, we returned to site to undertake a more in depth test on the block that when completed, will be one of the tallest in the UK. By using the same methods, products and dwell times over a large area of this block, we once again were able to create the required finish, while refining the process and achieving a more efficient delivery.
Finally, with both tests complete and the client fully satisfied with the results, we completed the full restoration of the initial block, and will be returning in Summer 2019 to complete the cleaning of Block A (64 floors).
The team at Building Transformation understood our challenge of finding a facade cleaning solution that would initially restore the glazing to its original state, protecting our building for years to come. Through intelligent and thorough testing right through to the full restoration of Block D, we have been very satisfied with the project management and delivery of the cleaning programme. We like the way the team works – using innovative, environmentally friendly methods, combined with the use of non-abrasive products, is helping us efficiently maintain our building and the beautiful architecture we are creating on the Manchester skyline for years to come
