FIS to take the lead in new cross-industry forum focussed on Building Safety

A new collaborative forum, The Passive Fire Knowledge Group (PFKG), has been launched to drive culture change through the design and construction process to improve fire safety in buildings.

The Passive Fire Knowledge Group (PFKG) brings together Tier 1 contractors, specialist installers and relevant trade associations to promote passive fire protection guidance and so improve the delivery of well designed, specified and installed passive fire protection. Tier 1 contractors comprise the largest stakeholder group and have the influence to drive forward the necessary culture change.

Commenting Will Pitt (Laing O’Rourke) of Passive Fire Knowledge Group (PFKG) said:

Tier 1 contractors are fundamental to managing the transition from design into the finished building and as such need to understand the procedures, systems and products involved. It is important that passive fire protection is adequately considered at planning and early design stages to ensure buildings are designed and constructed in accordance with relevant regulations. The PFKG aims to resolve the complex passive fire protection design challenges to ensure the construction industry delivers safe buildings.

Joe Cilia, (FIS Technical Director) and joint Chair added:

Trade Associations such as Finishes and Interiors Sector (FIS) and the Association for Specialist Fire Protection (ASFP) are able to bring specialist knowledge from within their technical teams and their wider membership through a collaborative approach to support this group meet its aims.

The PFKG will initially focus on education, process and testing issues related to the design and specification of passive fire protection for compartmentation, with initial focus on service penetration sealing and compatibility with fire resisting partitions (firewalls).

Other issues the forum will consider include: the appropriate application of fire test data to real life installations, inspection and recording of installed works during construction, and the education requirements of those designing, procuring and installing passive fire protection.

Tall Building Working Group publishes report on impact of building movement on drylining

Tall Building Working Group publishes report on impact of building movement on drylining

FIS and the Tall Building Working Group (TBWG) have published a report which investigates the causes of noise emanating through the fabric of some tall buildings, identifies methods of remediation and provides guidance for affected buildings.

The Tall Building Working Group (TBWG) was formed in 2018 to address a global phenomenon where creaking can be heard in tall residential towers in high wind conditions.

The group was established under the umbrella of trade body Finishes and Interiors Sector (FIS) and set about bringing together the entire supply chain, namely developers, tier 1 contractors, manufacturers, architects, specialist drylining contractors and engineers who are involved in the specification and construction of buildings where noise issues have been reported.

The starting point was to investigate the root cause of this phenomenon and then look at how occurrence can be reduced or better managed in new towers by providing better guidance for architects, engineers, designers and developers.

The group engaged with individuals and organisations from across the globe and absorbed the findings of all available secondary research before embarking on a structured research programme of their own, funded by members of the TBWG.

Further research was carried out by structural engineers WSP to present, in a graphical format, the inter-storey differential movement in vertical and horizontal directions affecting partitions and other elements of fit out. This document explains to the project fit out designer how a high-rise tower reacts to external loads.

  • External loads make building move: non-structural elements should be installed in such a way to allow for the movements freely.
  • Any locked in movement will cause distress in the non-structural elements.
  • Any frictional resistance to movements will cause noise.

The key to reducing the phenomenon occurring in future tall towers is sharing the information contained in the structural engineer’s movement and tolerance reports early with the system owners of the drylining, and providing movement joints to allow the elements of the internal fit out to move independently.

Manufacturers have been exploring different solutions and methods of mitigation. At this stage none have been able to completely eliminate the sound.

Commenting on the work, FIS CEO Iain McIlwee said:

“I think this is a first. I cannot think of a single time when the construction supply chain has attacked a problem in this way. Rather than battening down the risk hatches, reaching for the contract and starting the blame game, this was a genuine attempt to work together to understand and collaborate to solve it. This is a body of work all involved can be proud of, not just because it will help unravel some potentially complex issues or maybe help people sleep more soundly, but because it is an example of how we can collaborate and be better as an industry.”

The TBWG is planning to hold another conference to share the report outcomes with the delivery teams, meanwhile a summary report is available here.

FIS Best Practice Guide defines ‘Through-Wall’ systems

FIS Best Practice Guide defines ‘Through-Wall’ systems

FIS has launched a new Best Practice Guide for Through-wall infill steel framed systems (SFS) to provide a standard definition of ‘through-wall’ and assist in the design, specification and installation of SFS ‘through-wall’ systems.

‘Through-wall’ has become a generic term used by suppliers of systems to describe infill exterior walls constructed from Light Gauge Steel Frame (LGSF) sometimes described as steel framing systems (SFS) where frame, inner plasterboard and external sheathing boards are tested and sold as a system. However, in a similar way that the framing can be defined as LGSF and SFS, there is no consistency in what constitutes ‘through-wall’.

The guide has been drafted by a panel of experts from the FIS SFS working group in conjunction with the Steel Construction Institute (SCI) and the Association for Specialist Fire Protection (ASFP).

Aimed at everyone in the delivery chain from design to specification, fire engineers, contractors, site managers and installers, it explains the three options:

  1. From inner plasterboard to external sheathing board
  2. From inner plasterboard to external sheathing board and external wall insulation
  3. From inner plasterboard to external sheathing board, external wall insulation and façade system

Commenting, Andrew Way, Associate Director at the SCI, said:

“The term ‘through-wall’ has been in common use in the construction industry for many years now, but its precise meaning is still unclear for many people. This is not surprising as a recognised definition of ‘through-wall’ has not been provided up until now. This joint publication from FIS and SCI addresses the need by providing a clear definition and presenting useful information about the topics and performance characteristics related to ‘through-wall’ systems. The leadership of FIS in driving this publication has been critical in achieving this new guide for the industry to utilise”.

Dr Andrew Taylor, Technical Officer at ASFP said:

“Understanding the impact of different component materials on the ability of a constructed system to perform, together with how the system interacts with the structure and any potential movement, is fundamental to the delivery of a successful installation.”

“LGSF, SFS and through-wall are still emerging technologies and solutions as part of Modern Methods of Construction (MMC). It’s vital that their integration and interface into the building structure to ensure the performance requirements can be met and what clear evidence of compliance is required is addressed as early in the design stage as possible,”  added FIS Technical Director Joe Cilia.

The guide is freely available to FIS members from the FIS website at https://www.thefis.org/membership-hub/publications/best-practice-guides/through-wall/ and will be used to form the basis of Continuous Professional Development programmes going forward. Copies are available to non-members on request.

Technical guidance note on BS EN 13964: The language of Suspended Ceilings

Technical guidance note on BS EN 13964: The language of Suspended Ceilings

FIS has produced guidance that is designed to support and enable better understanding and engagement with BS EN 13964.

The guidance note aims to break down the standard into bite sized sections making it easier to understand to those who aren’t already familiar, allowing anyone to isolate only the sections that are relevant or of interest and gain either a passing understanding or to establish the necessity of purchasing the full standard. Where appropriate, each section covered will also give relevant commentary on reasonable expectations of products in the marketplace today.

Whilst the guidance is not designed to replace the standard and should not be relied upon to relay comprehensive detail and listings, it will prove useful to anyone who is not sure if the standard applies to certain products, are using the standard for specification purposes or simply wish to understand more about the reasonable expectations of performance requirements of a suspended ceiling.

FIS has previously published a comprehensive Specifiers Guide to Ceilings and Acoustic Absorbers that references BS EN 13964, but gives specification advice based on all common ceiling types and associated market expectations of performance and tolerances etc so the advice is not constrained to only those types of ceilings covered by the standard.

Urgent safety warning issued over fire dampers

Urgent safety warning issued over fire dampers

The Building Engineering Services Association (BESA) has issued an urgent warning to all contractors over the safety of fire dampers.

Inspections by maintenance contractors found that a “huge number of dampers” had been incorrectly installed and would fail to work during a building fire.

BESA’s head of technical Graeme Fox has urged contractors to “alert their clients immediately” so that rectification works can begin.

The issue revolves around the use of self-drilling “tek” screws which have been used to install an unknown number of dampers in projects. The screws have a higher melting temperature and do not melt if a building is on fire.

“This means that spring-loaded dampers will not be released to contain the spread of fire within the zone and ensure the integrity of the fire stopping measure,” Fox explained.

“Dampers must be secured by fusible fixings that allow the duct to break away, otherwise the collapsing duct could pull the damper out of place and break the seal between the fire zones,” he added.

BESA published a special announcement on the subject. It includes updated guidance and statutory requirements covering installation, testing and maintenance of fire dampers and smoke dampers.

The document also highlights clients’ legal obligations to ensure their fire safety systems remain fit for purpose in line with the Regulatory Reform (Fire Safety) Order 2005 for England and Wales and the Fire Safety (Scotland) Regulations 2006.

Fox said: “While this is clearly a very worrying situation, we can take some reassurance from the fact that this problem is being brought to our attention by the increasing frequency of fire damper inspections and tests as awareness grows of this extremely important issue.”
