Facade retention is most commonly required when the internal floor structure of a property is changed. The systems provide invaluable structural support to reduce the risk of collapse if the facade is being disconnected from the supporting floors. They also help to retain the overall appearance of the building as this work takes place.
The idea behind retention systems is that they prevent excessive movement in the facade, thereby reducing the risk of cracking and instability. This in turn preserves the exterior of the building, improving safety in the process. It is common to see the technique used on listed properties, where the character of the exterior needs to be protected and retained.
There are several different types of retention systems to choose from to suit the needs of different properties. Scaffolding is the most common type and is generally used for properties up to four storeys tall. Proprietary retention systems use props, ties and braces and are regularly employed on taller facades. Fabricated steel framework may also be used when the system needs to be in place for a longer duration.
With each retention system, it is important to ensure that there is enough stiffness to prevent excessive movement. The supports need to be able to support the weight of the facade throughout and keep it stable. The stability needs to be maintained in every direction to prevent cracking or collapse, this means wind and impact loads need to be taken into consideration.
