Case Study

Centrillion Point Reclad, LB Croydon

South London

Centrillion Point comprises nearly 190 units on 12 floors, on the edge of Croydon’s Cultural Quarter, which is currently undergoing a multi-million pound regeneration. 

The reclad contract was to remove the existing terracotta and combustible Alucobond; install new fire barriers; reinstate terracotta and install new A2 fire-rated Alucobond.

Challenges

There were no ‘as built’ drawings.

 

 

The existing sub-grid was defective. Early intrusive surveys identified the existing support system was inappropriate to support the replacement cladding.

 

Scaffold connections to existing structure was a challenge. The slab edge had been extended during a previous refurbishment. There was no clear fixing point for the scaffold ties.                                                  

 

 

 

 

 

There was a fire risk of exposing the cavity during the cladding strip. As panels and insulation were removed, the top of the cavity was exposed. 

There was a risk that a cigarette, for example, could fall from a balcony into the cavity and ignite the combustible insulation.

Solutions

A2O carried out a full 3D scan of the building to establish datum levels and size replacement panels.

 

A2O designed a replacement support system for the new A2 Alucabond panels and feature band.

 

 

A2O worked in a continuous attendance with the scaffolding contractor to cut back cladding and CP board and to remove insulation to get back to a suitable structural member for scaffold ties.  

Non combustible insulation and membrane were used to temporarily fire protect and weather.

 

 

As the cladding strip progressed, A2O fitted a temporary metal tray flashing to close-off the top of the exposed cavity to prevent anything dropping into the cavity.
