Client: Encore Estate Management
Management Surveyor: BBS Surveyors
Fire Engineer: BB7 (Omega Fire Engineering Limited)
Recladding works required as a result of the Grenfell Towers Tragedy
Project Value
Recladding Contract Value: Circa £2m
Full Scaffold and Roof Edge Protection - Rope Access
Building Height: 30m
Access Considerations include the proximity of the building to a main traffic artery as well as the adjacent rail line.
Access Strategy:
- Full Perimeter Scaffold Access with external debris netting.
- Rope Access Works to Rail Elevation where rail proximity was cause for concern with respect to scaffold access.
Under Habitation - Poor Existing Construction
When considering how best to tackle the recladding of this building, it was key that we took into account the issues the inhabitants had had with the cladding since the project had been complete. This meant looking at strategies to weather the building and ensure seals were in place prior to simply installing the replacement cladding panels and substructure. This was particularly necessary to prevent water ingress and unpleasant internal conditions caused by inadequate seals during the replacement works.
By installing an A1 Rated CP Board to the existing block and sealing this to the concrete structure, ensuring a Fire Rated Sheathing to the building, this also allowed us to get the building weathertight prior to the recladding work. It formulates part of our strategy 'Make Safe - Then Replace' in terms of strip, survey and fabrication, permitting the building to be sealed and externally exposed for up to 1year before cladding would be required.
The insulation was previously a 60mm Celotex Board, we will be installing an A1 Rated Mineral Wool Rainscreen Panel in its place.
Ceramapanel Panels are installed externally to ensure compliance with a full A1 Rated throughwall.
