Regulation 7(2) would require the same as achieving an A1 rating on the EWS1, in that all combustible materials (primarily timber) would need to be removed from the makeup of the external wall and replaced. Regulation 7(2) is prescriptive and specifies that all materials in the external wall, with very limited exceptions, must be of limited combustibility.

Question 23

What was the make up of the replacement wall at Francis Bacon Court with?

Answer 23

REPLACED WITH MARLEY EQUITONE PANELS.
90 minutes intumiscent “siderise” cavity barriers.
Remove temporary breather membrane & replace.
new carrier aluminium rail system. “Nvelope Rainscrean system”
Alideck

branded as B-s1,d0
The Steni Colour panels: The HPL cladding manufacturer
the supporting substructure is concrete slab, timber and cement block
It is used as a open joint rain-screen system which requires horizontal cavity barriers at each floor and around openings. The horizontal cavity barrier in this system should be intumescent to close the cavity only in case of fire. The damage to the installed mineral wool at second level shows that the detail has not been built to the standard required for a rain-screen system. The insulation is missing in most areas. It was observed in front of the floor slab to be Celotex which is not limited combustibility. It is suspected that the main insulation is behind the blockwork and the insulation added in front of the slab is to stop a cold bridging only.

B rated cladding.
Lack of properly installed cavity barriers.
Flammbile insulation
timber in walling.
balconies stacked with timber decking.

Answer 30

◼ Used when the nature of the work is known but cannot be quantified
◼ In the absence of an estimate, contractors quote unit rates against a document
that is intended to cover all likely activities that might for part of the works

What is s78 building act 1984

2 / 2

ChatGPT

Section 78 of the Building Act 1984 is a provision in the United Kingdom that empowers local authorities to serve notices requiring the execution of necessary works on a building. The purpose of this section is to address situations where a building is in a dangerous condition or is considered to be a risk to the safety or health of the occupants or the general public.

Under Section 78, if a local authority has reasonable cause to believe that a building is in a dangerous condition, they may serve a notice on the owner or occupier of the building. The notice will specify the works that are required to be carried out to eliminate or reduce the danger. The local authority can also require the building to be vacated until the necessary works are completed.

If the owner or occupier fails to comply with the notice, the local authority may take further action, which may include carrying out the necessary works themselves and recovering the costs from the owner. The local authority can also apply to the court for an order to secure compliance with the notice.

It’s important to note that Section 78 of the Building Act 1984 specifically applies to England and Wales. Different legislation may apply in other jurisdictions. Additionally, since my knowledge cutoff is in September 2021, there may have been updates or amendments to the law since then. Therefore, it’s always a good idea to consult the latest legal sources or seek professional advice for accurate and up-to-date information.
