The Normanby Mews project involved recladding and re-roofing of a 48 apartment complex comprising of four x four story buildings.
The remedial works consisted of the following:
- Deconstruction of existing fibre cement cladding
- Construction of new roof and gutters
- Replacement of rotten timber framing
- Installation of RAB (rigid air barrier) and cavity system
- Rebuild/waterproofing of decks
- Installation of aluminium Nu-wall cladding
- Passive fire compliance upgrade
The project was undertaken in four separable portions allowing for a ‘staggered programme’ and re-occupation by residents as the contract progressed and each block was completed.
Each block had individual scaffold and weather protective shrink-wrap encapsulation. Existing fibre cement cladding was removed revealing the need for extensive timber replacement.
Installation of the aluminium Nu-wall cladding involved construction tolerances of less than 3 millimetres requiring very precise workmanship.
All blocks were also found to be non-compliant with passive fire requirements of the building code, so further corrective work was undertaken as a variation.
Given the staggered nature of the programme and the nature of the site (being progressively occupied), attention to health and safety; specifically separation of the public from work faces was especially detailed and strictly adhered to.
