What is timber Frame?

2 What is timber Frame? Timber Frame is a method of construction where the load from the floors and roof is transferred to the foundations via the timber frame panels within the walls. The timber frame panels are typically made up of vertical timber studs at between 450mm and 600mm centres, formed into a rectangle using horizontal timbers at the top and bottom of the vertical studs.

3 What is timber frame? These horizontal and vertical studs are typically clad with plywood or Oriented Stand Board (OSB) sheets for added stiffness (Racking). The roof and floor loads are transferred through the vertical studs.

4 Timber frame in a fire. The removal of a small number of studs will not result in the collapse of the building. The timber frame building is design against disproportionate collapse. Therefore the damage caused to the building as a whole will not be disproportionate to the damage (fire, impact, rot, explosion etc) inflicted on it.

5 Timber Frame All buildings, whether timber frame, masonry, steel, etc are built to meet the same fire building regulations (fire resistance, surface spread of flame, (non)combustibility etc). All building types also require the same type and location of cavity barriers/fire stops.

6 SiteSafe... an initiative by the UK Timber Frame Association (UKTFA) to minimise the risk of fire on timber frame construction sites

7 How did we get here? Peckham Fire 26/11/09 Emergency Board Meeting 1/12/09 Numerous press interviews Meet with ABI and CFOA 10/12/2009 SiteSafe working session 16-17/12/09 SiteSafe working session 18/1/10 Further teleconference calls

8 Adoption of Site Safe will be a mandatory requirement of membership of the UKTFA for large projects

9 SiteSafe UKTFA Member Company Responsibilities 1.To implement SiteSafe across their business 2.To embed SiteSafe within Member Company s audited business process procedures (e.g. ISO9001) or for Member Companies who do not have ISO9001, the SiteSafe compliance will be audited by BM Trada 3. All identified major non conformances to SiteSafe are to be notified to the UKTFA by the independent auditor (e.g. BM TRADA or UKTFA auditor). This is to be written in the Member Company s procedures

10 Large Projects 4 storey or more and/or Have an aggregate floor area of >2,500m2

11 We need a Collaborative Approach

12 SiteSafe a 3 stage process Stage 1. Pre-construction Planning Stage 2. On site (During Construction) Stage 3. Offsite (Post timber frame construction) For supply only contracts, Stages 1 & 3 must be followed. For supply and erect contracts, Stages 1,2 & 3 must be followed

13 Stage 1 Pre construction Planning Key Documents: UKTFA Health & Safety Code of Practice UKTFA 16 Steps to Fire Safety on Timber Frame Construction Sites Joint Code of Practice for Fire Safety (Construction Confederation, Fire Protection Association) Construction (Design and Management) Regulations 2007 HSG168 (HSE document fire safety on construction sites)

14 Stage 1 Pre construction Planning Key Steps Large projects are required to be registered with the UKTFA. CDM Co-ordinator details to be requested. CDM Co-ordinator notified of the Member Company s details/sitesafe Contractor s Fire Plan requested. Review Fire Plan and make suggestions in respect of risk. Agree build sequence and handover procedure. Identify responsible person appointed by the PC to monitor Fire Safety under CDM. The Member Company must notify the relevant Chief Fire Officer

15 Stage 1 Pre construction Planning

16 Stage 2 On Site (during construction) Site Visits By Member Company s Health & Safety advisor or Competent Person (NEBOSH) - will include a review of the site Fire Plan. Non conformances brought to the attention of the PC at the earliest opportunity, preferably at the time of the visit. A written report submitted by the health and safety advisor or competent person to the Member Company - non conformances/actions. Copy to PC. Member Company to assess if reasonable to continue if PC fails to fulfil its duties regarding fire protection of the site. It may be necessary to inform a 3 rd party (HSE / Insurer) to assist.

17 Stage 2 On Site (during construction) Other actions: Identify responsible person appointed by the PC to monitor Fire Safety. All parties must monitor and maintain 16 step plan and HSG 168. Where changes to the agreed build sequence occur and for example leaves the structure partially completed or unprotected, a revision of the site Fire Plan may be required. Significant changes to design or sequence should be assessed by the Member Company for their impact on fire safety and copied to the CDM Coordinator. (Appendix 5)

18 Stage 2 On Site (during construction) Check List:

19 Stage 3 Off site (post frame construction) Copy of signed handover or equivalent received Principal Contractor reminded of Fire Plan Content in relation to Timber Frame for follow on trades and contents of documents handed over in stage 1 Registration closed with UKTFA

20 Stage 3 Offisite (post frame construction) Check List:

21 Summary SiteSafe Fire Safety Guidelines already published not new. SiteSafe is procedural, auditable and robust. Administrative costs kept to minimum. Essential we achieve 100% conformance among membership

22 Summary SiteSafe Non conformance: No adoption of SiteSafe one strike and out. Major procedural non-conformance two strikes/year and out. Minor procedural continuous improvement.

23 Summary What s next Step 1 - Agreed contract with BM Trada to review SiteSafe policy Step 2 Series of external audits of member companies will be carried out in June 2010 by BM Trada Step 3 - Recommendations on further measures to protect timber frame from intrusion second quarter 2010 Step 4 R&D project to investigate further measures once site and timber frame penetrated second quarter 2010.
