  • Sample Temporary Works Procedure TWf2019: 03
    Following the publication in May 2019 of BS5975:201, the TWf published in December 2019 a sample procedure on temporary works. Aimed specifically at the small and medium sized companies, it gives suggestions for a procedure, and includes sample appointment forms for both TWC and TWS, a sample yet simple TW register, sample design check certificates, inspection records, as well as useful responsibility and organisation flow charts.

    Peter Pallett has some reservations on this SME sample procdure, and hopefully a revised version will be available in the near future. This web site will announce it when it is available.

  • Temporary Works Training - Information Sheet 2 Rev A
    The Temporary Works Forum issued on 18th October an update to their popular Information Sheet No. 2 to include the latest requirements and pre-requisites for delegates and trainers following the publication of BS5975:2019 and the CITB Appendix L (August 2019) and N for various courses.
    This information sheet is a MUST READ for all those procuring temporary works training, and anyone wanting to asess what type of training they might need before being appointed a PC's TWC, TWC or a TWS, or just for CPD in technical awareness. The Frequently Asked Questions (FAQs) have been extended to answer the most common queries on training.

    CITB Scheme Rules - Appendix L , published in August 2019, Clause 12, requires the trainer to hold a current TWCTC course certificate and comply with the following three criteria:
       (a) be a member of AMICE / MICE / FICE / MIStructE / FIStructE / InstRE, and
       (b) be registered with Engineering Council as IEng or CEng, and
       (c) hold relevant practical and design experience of temporary works.

    To ensure that these criteria are met, BS5975:2019 (Cl 5.2.3) recommends that all those procuring training should assess the actual trainer and NOT the training provider for competence. This is to ensure that the trainer is actually up-to-date technically and has the necessary practical experience in temporary works. Both the training provider and CITB have a duty to ensure that the scheme rules are being followed. The individual trainer should have no objection to allowing their CV to be made available to the procuring organisation to satisfy compliance with Appendix L.

  • Backpropping Flat Slabs

    Graph Two levels The current method of assessing the load transfer through floors has been based on the ECBP Research work carried out at the turn of the century. (BRE Report BR394 in 2000) The flat slab insitu concrete industry now builds longer, more slender slabs than those envisaged in the 90's. Peter Pallett and David Szembek (Byrne Bros (Formwork)) have revisited the research data and using the ECBP backpropping spreadsheet, have established a more realistic criteria for load transfer, particularly for those slender structures with span to depth ratios exceeding 30. Research into the preload inserted into backprops, plus consideration of whether the propping is fitted as "one for one" or with "50% fewer" backprops has resulted in a revised graphical solution for ECBP Method One simple backpropping analysis.

    Download the Peter Pallett's latest handout PFP/136F on backpropping by clicking on the link to read more.
    This revised method, together with further explanations on backpropping, is available as Chapter 28 in the 2nd Edition of the ICE "Temporary Works - Principles of Design and Construction" published December 2018.

  • Training Managers in Temporary Works
    BS5975:2019 ( Cl. 5.2.1) recommends that all those managing temporary works should have an understanding of :-
        a) the procedures outlined in Section 2 of BS5975,
        b) the procedures that you are expected to operate for your organisation,
        c) management of risk associated with your managinmg the temporary works,
        d) technical knowledge relevant to both your role and complexity of the work, and
        e) practical knowledge relevant to the complexity of the job.
    Certain projects might in addition have job-specific training requirements ( e.g. railway work, airports. )

  • The Temporary Works Training Courses (TWC, TWS & TWGA) UPDATE and Refresher Course

    The TWC two day course (started June 2014), the TWS one day course (started September 2014), and the more recent TWGA one day course (started August 2015) were all established by CITB with TWf endorsement. ALL tutors must be full members of either MICE or MIStructE - and not safety professionals! For more information see TW16.005 TWf Information Sheet No.2 Rev A - Temporary Works Training linked in paragraphs below.
    Although Peter Pallett has retired, both Ray Filip and Anita Ballard still run these courses and had to undergo extensive Level 3 Education and Education training (formerly PTTLS), and then take and pass the CITB course and examination. Available as In-house or public courses, I suggest you look at the links in Training to see Peter Pallett's recommendations.

    Refresher Courses. The TWC, TWS & TWGA course certificates are valid for five years. TWf and CITB are currently in discussions to consider a one day refresher course. The intention being to start such refresher courses in mid 2020.

    • Pedestrian Bridge Collapse in Florida - Report
      The US Occupational Safety and Health Administration have published a frightening report on the collapse of the bridge under construction onto a road killing six people. Not only is their a lack of adequate procedures for controlling the construction and the temporary works, but the lack of even basic knowledge of engineeering principles is frightening. It seems the independant checker did NOT check the temporary states during construction. When the cracks were spotted, well before the day of collapse, why did no engineer stop the traffic underneath? It seems they failed to consider shear across the end diaphragm in the temporary condition, then stressed the bars and increased the compresion, when it was already in compression in the temporary condition. It also doesn's appear to have much bursting reinforcement in the compression members!

    • ing the UK research work on friction. The date is also introduced into BS 5975:2008.
      The friction resistance using “wet” timber and plywood has shown that the values previously published for DRY timber and plywood are acceptable lower bound values. Surprisingly, wet and saturated timber and plywood gave higher values than when dry - believed caused by the individual timber fibres compressing when wet and making a "rougher surface".

    • Trough and Waffle Floors
      An article in CONCRETE Apiril 2019 (pages 18 and 19) by Alan Coker of ATEX reminds us all that whereas these very familiar types of construction were popular in Europe about 20 years ago, they are currently very popular in overseas markets ; particularly South Africa an South America. He asks why UK consultants haven't re-investigated there use, particularly as TR42 remains the best practice technical report, or is it lack of advertising and promotion by the mould suppliers?

    • Use of CPF for Enhanced Durability
      Having contributed to the research and positive effects of Controlled Permeability Formwork, I was very pleased to read the article in the April edition of CONCRETE (pp 30 to 31) on the use of a proprietary self-adhesive non-woven CPF liner on the prestiguous V&A building recently completed in Dundee. The double curvature of many of the walls meant that tensioning the liner normally was impossibe, hence use of the self-adhesive type.

      The Concrete Society Technical Report No 52 (Second Edition) is now published. This revised edition introduces compares the various specifications currently in use - BS EN 13670, NCSC, NBS, CESWI, SHW and earlier BS8110. A very useful Table 2 summarises an approximate comparison. The updated report illustrates twenty four different sites, with three colour photographs from each site of a plain concrete finish. Details of how the finish was achieved, the specification used etc. together with the concrete mix details, type of form face etc., are all included. It includes the CONSTRUCT reference panels. At long last, the industry has authoritative guidance on the subject.

      The work was carried out by the University of Birmingham, led by Eur. Ing. Peter Pallett with help from Dr. M. Burrow, Professor L. Clark and Mr Ray Ward. The research investigated both the aspects of stability of falsework and measured eleven sites for accuracy of erection. The changes in management of falsework, together with more reliance on suppliers' designs has led to different criteria and checking regimes.

        There does not appear to have been an overall improvement in verticality of erection over the last 12 years.
        At all levels there is a lack of understanding of the fundamentals of stability of falsework and the basic principles involved.

      The Health and Safety Executive published in (December 2014) their guidance to clarify when a scaffold design is required and what level of training and competence is needed following publication of the NASC TG20:13. The six pages are available to print from the HSE web site at www.hse.gov.uk/construction/safetytopics/scaffoldinginfo.htm

    • TG20:13 Operational Guide and Design Guide
      TG20'sTG20&058;13 was first published in February 2014 as two volumes. An Operational Guide with supportive eGuide CDROM disk, and a separate Design Guide.

      The safe height tables are removed, and replaced with Compliance Sheets obtained using the eGuide disc. A different method of wind load evaluation is now used.

      In addition to tube and fitting transoms, the eGuide permits the use of TG20 Compliant Structural Transom Units, but it is the user's responsibility to ensure that the transom units used ACTUALLY comply - it is known that some do NOT!
      The TG20:13 also allows use of the thinner high yield S355 steel scaffold tube under controlled conditions.

    • TG20:12 - Supplement No. 1 - Wind and Safe Height Tables
      TG20_Supp 1Updated in January 2012 this revision of the scaffold SAFE HEIGHT TABLES is only available as a free pdf download. It includes the update to the UK wind map introduced in March 2011. It uses the simplified wind method with S wind method and the updated FOUR safe height tables. The Appendix H for tying to permeable open structures is included in this supplement.

    • TG9:12 Guide to the design and construction of temporary roofs and buildings
      This guidance by the National Access & Scaffolding Confederation, was republished in January 2012, and is the essential authoritative guidance to the safe erection and design of temporary buildings.
      It uses the information on wind loads for the UK using the NA to BS EN 1991-1-4:2005+A1:2010 (from January 2011) TG9:12 is only available to NASC members as a pdf download from www.nasc.org.uk.
