Q

What is the Hackett Report?

A

Following Grenfell Dame Judith Hackett undertook an independent review of the Building Regulations and in particular their impact on fire safety. The key findings included:

  • the roles and responsibilities of those procuring, designing, constructing and maintaining buildings are unclear.
  • the processes that drive compliance with building safety requirements are weak and complex with poor record keeping and change control in too many cases;
  • the product testing, labelling and marketing regime is opaque and insufficient
  • the voices of residents often goes unheard, even when safety issues are identified

Recommendations (fire safety act 2021:
- a set of rigorous and demanding roles and responsibilities for “duty holders” (i.e. building owners) to ensure a stronger focus on building safety;
- a series of robust gateway points that will require duty holders to show that their plans are detailed and robust;
- clearer rights and obligations for residents to maintain the fire safety, working in partnership with the duty holder
- a package of regulations that is simpler to navigate but genuinely reflects the level of complexity of building work

Q

What are the key features of the Building Safety Act?

A

The legislation is intended to enhance regulations for building safety and ensure residents have a stronger voice in ensuring safety in buildings.

  • Accountability for the duties of those responsible
  • Resident ability to contribute to maintain safety
  • Enforcement to deter non compliance
  • A national framework for the suitability of materials
  • removal of combustible cladding to buildings over 18ms
  • Three gateways to ensure compliance at planning, pre-construction and pre occupation
17
Q

What is an ACM panel?

A

Aluminium composite material. A sandwich cladding material with a polyethylene core.

18
Q

What survey was undertaken which exposed the lack of fire breaks in the building? What stage of the project was this?

A

An investigation was instructed by my client to make the most of having the scaffolding being in place around the building. This was following the advise of Building Control who advised similar buildings in the area had been found at fault.

The project had commenced on site and therefore these works were instructed under the D&B contract.

19
Q

What is a fire break?

A

A physical barrier inserted to a wall to prevent the spread of fire. Typically rockwool insultation product or concrete.

20
Q

Who discovered that the fire breaks had not been installed?

A

The main contractor

21
Q

What is the role of building control?

A

Building Control is primarily about ensuring building work complies with minimum standards for Health and Safety of persons in and around buildings, conservation of fuel and power, and accessibility.

22
Q

What is an approved inspector?

A

An approved inspector is a company that provides an alternative route to local authorities to review work completed to ensure alignment to the Building Control standards. They are normally quicker in response to local authorities.

23
Q

What is the golden thread?

A

The information that allows you to understand a building and the steps needed to keep both the building and people safe, now and in the future.

24
Q

Please explain the process undertaken for the cladding replacement

A

The cladding was removed in a methodical manor around the building via scaffolding. A hoist was installed to allow materials to be swiftly lifted to the correct level

25
Q

What additional H&S measures were undertaken given the building was fully occupied during the works?

A
  • A competent contractor was appointed who had experience in cladding removal and replacement in occupied buildings.
  • All operatives were trained at working at height and wore 5 point PPE.
  • The scaffolding was netted and included signage. this was alarmed and all residents specifically informed not to enter.
  • Ladders were removed at the end of each shift to avoid access onto the scaffolding.
  • catch platform installed to catch any potential objects dropped from height.
26
Q

Who specified the new cladding and what was this?

A

The architect specified an Alucobond panel.

27
Q

What was the role of the fire engineer?

A

To assess the scope of works in relation to the building fire strategy and fire regulations. Review design options and advise on complaint solutions.

28
Q

You said you referenced approved document B. What was covered in this and why did you reference it?

A

Approved document B: fire safety.

It covers guidance on how to meet building regulations in relation to fire safety and covers areas such as means of escape, fire spread, structural fire protection and fire engineering items.

BS 9999 - British Standard. Code of practice for fire safety in the design, management and use of buildings, provides a best practice framework for fire safety. It covers fire safety in the design, management and use of residential buildings. Code of practice.

29
Q

Who advised the concrete slab was adequate fire protection below the penthouse flats?

A

The fire engineer

30
Q

What is the BCO? Is this legislation?

Q

Why did you advise the client to follow BCO guidance?

A

This was a requirement from the letting agent and a best practice item that would be beneficial to letting the space.

32
Q

What is approved document G?

A

Sanitation, hot water safety and water efficient. This includes:

  • Bathroom provisions
  • Drainage discharge
  • Layouts
33
Q

What are the recent updates to the Approved documents?

A

Came into affect June 2023:
F - Ventilation
L - Conservation of Fuel and Power
O -Overheating
S - Electric Vehicle charging

Updated to reflect the UK target of net carbon zero by 2050

34
Q

What is net lettable space?

A

Gross Lettable Area is calculated using measurements from external walls, however NLA is calculated using measurements taken from the internal finished surfaces of permanent walls and dominant portions of the permanent outer building walls.

Therefore, the measurement does not include columns, piers or structural columns. It also does not include areas provided as standard common area facilities like lifts, toilets and tea rooms and excludes areas that house plant and equipment like air-conditioning and power services.

35
Q

What sections were included in the feasibility report?

A
  • Description of the existing building
  • Description of the proposed works
  • Options review
  • Budget review
  • Planning / statutory consents
  • Porgramme
  • Risks
