  • Clients' guide to temporary works

    The Temporary Works Forum (TWf) have published an authoritative 40 page A4 guide for Clients, their representatives, programme managers and others on the design and coordination of temporary works; written at the request of a group of clients. These clients were aware of the risks and, in some cases, the lost opportunities to their enterprises that temporary works present, but felt disadvantaged because they had insufficient insight into the processes at work in temporary works management. The document Ref: TWf2014:02 is available as a free download either as *doc or *pdf file from the TWf by clicking on the link TWf2014:02

  • DRAFT CDM Regulations 2015

    Subject to Parliamentary approval, the new Construction (Design and Management) Regulations 2015 will come into force on 6th April 2015. (The industry comments on consultation CD261 up to June 2014 have been considered.) Download the final draft from the HSE or click on link at Draft CDM Regs.

    Also published as free drafts for download are an HSE Guidance (Ref L153) and SIX separate industry guidance documents:-

    Draft L153 HSE Guidance on the CDM Regs 2015
    Draft guidance for Clients
    Draft guidance for Workers

    Draft guidance for Contractors
    Draft guidance for Principal Contractors

    Draft guidance for Designers
    Draft guidance for Principal Designers

    It looks like being an interesting few months ahead until CDM 2015 is government approved and published in April!

  • Making BIM fit the form - Temporary Works

    This two page article in the New Civil Engineer's Infrastructure Report 2015 in NCE of 18th December 2014, highlights the fact that Temporary Works is NOT included in the government's BIM requirements currently driving UK adoption of BIM. The interview of Ian Fryer, RMDK engineeering director, gives a refreshing view on the likely future of 3D modelling in Temporary Works and the opportunities possible. It includes examples and explains how how RMDK have created life-like visual presentations of their products for inclusion in BIM.

  • HSE - Scaffold Checklist

    The Health and Safety Executive have recently updated (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

  • CPA 1402 - Ground Conditions for Construction Plant.

    The Strategic Forum for Construction published in October 2014 a Good Practice Guide in the assessment, verification and specification of the ground for construction plant. Avoidance of failure of the ground on which construction plant stands is a significant temporary works issue. The guidance deals with ground bearing pressures and loadings from mobile plant, and assessment and engineering of the ground's capability to withstand the loadings. It addresses coordination of duties, with reference to CDM and to Temporary Works, and contains technical guidance presented in an accessible way.

  • Structural Anchors

    An NCE Special Report on Structural anchor advances published with the 25th September 2014 edition of NCE highlights the latest information, testing and specifying of the structural anchors often used in both temporary works and permanent structures. The new European Legislation has made it more important than ever that TW designers, engineers and specifiers understand if the products offered are fit for purpose. This eleven page report also highlights the the meaning and interpretations for the CE marking of products. Worth a read.

  • TG20:13 Update

    The NASC updated TG20:13 with Supplement 1 ( 4 pages) on 22nd September 2014 to accompany the eGuide software update entitled version 1.1. Existing licenced single computer users of the eGuide can download the update for free. For information on standalone PC's contact the NASC.
    The main features of the update are introducing a compliant 3.2mm wall cold formed steel tubes, compliance sheet sign off section says diagrams are indicative, compliance sheets for sheeted scaffolds with transom units, new compliance sheets for scaffolds below 6m (i.e. housebuilding NOW addressed! ) and clarification for tie spacing for scaffolds with bay lengths less than 2m.

  • The Temporary Works Coordinator Training Course (TWCTC)

    The TWCTC two day course established by TWf and CITB, is now available to be presented by Eur. Ing. Peter Pallett with Co-ordinated Training Services Ltd, his Cskills ssp provider. The first courses are already filling quickly - see Public Courses.

    Peter Pallett and Ray Filip commenced the CITB registration process to present this course in November 2013. In order to qualify they had to undergo extensive PTLLS Level 3 training, and then take and pass the CITB two day course and examination. They both took the examination on 24th April 2014, but it was not until Monday 16th June 2014 that they received their certificates i.e. EIGHT months to qualify!

    Please be aware that Cskills changed the scheme rules for this course on 11th July 2014. The CTS course gives greater credence to Temporary Works and its co-ordination with the actual use of BS5975, rather than just risk management.

    After Peter's first course several delegates said "That was the most enjoyable, professionally presented course I"ve ever been on - the enthusiasm and knowledge of the speaker was infectious! "

  • CUBS Certificate Rules and Fees for Expert Witnesses

    On 1st April 2013 the Civil Procedures (Amendmemnt) 2013 Rules come into place. Known as the 'Jackson Reforms', these implement the most radical changes ever een to civil procedures, aimed at controling costs and metods of funding litigation. Each party now requires permission from the court to use an expert witness.

    In August 2014 the Criminal Justice Council issued revised guidance in connection with instructing Experts and litigants with regard to Part 35 of the Civil Procedure Rules.

    The change requires that ALL Experts must demonstrate to instructing solicitors that they both comply with, and have a full understanding of Part 35 of the CPR, Practice Direction 35. Eur. Ing. Peter Pallett is already trained as a holder of the CUBS (Cardiff University and Bond Solon ) Civil Procedure Rules Certificate and is underfoing training on the Jackson Reforms.

    • FRICTION in Temporary Works
      First published in the June 2002 edition of CONCRETE magazine is the article summarising 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".

    • Concrete Groups for formwork pressure
      Users of CIRIA report R108 need the relevant concrete group for determination of the pressure of concrete on formwork. Additional research has been carried out to advise CIRIA about the pressures for a range of superplasticised and self compacting concretes.
      Peter Pallett's article in CONCRETE magazine March 2009 (page 44 & 46) relates the new cement designations to the factors used in CIRIA 108.

      The working party currently updating CS030 Formwork - a guide to good practice have recommended that to avoid confusion in future, the industry classifies pressure determinations into three groups, as opposed to the seven groups currently used. These will be:-
      Group A - Basic Concrete ( Formerly Groups 1 & 2 )
      Group B - Retarded Concrete ( Formerly Groups 3, 4 & 5 )
      Group C - Heavily Retarded Concrete ( Formerly Groups 6 & 7 )

      Published in September 2003 by CIRIA, these major new references for all those involved in façade retentions include detailed design information and practical guidance. The CIRIA committee, under the chairmanship of David Thomas (HSE), must be congratulated for bringing together the differing design approaches previously used in the industry into one unified design approach. An on-site best practice handbook ( C589 ) in convenient A5 size is also available.

      C579 is ISBN 0 86017 5789 0 and C589 (A5 handbook) is ISBN 086017 589 8
      (Available direct from CIRIA Publications (Tel: +44 (0) 20 7549 3300) or email to CIRIA or from the web at www.ciria.org.uk quoting C579 or C589.)

      The HSE 200 page report is available as Contract Research Report CRR 394/2001 from HSE Books as ISBN 0 7176 2232 0. It is also available for download from www.hse.gov.uk/research/crr_htm/2001/crr01394.htm (2.5 Mb).

      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.

    • Work at Height Regulations Question and Answer Brief - Question 24 Scaffolding
      The Health and Safety Executive revised their website Question 24 in January 2006. The revised and corrected text is:

      • Question 24. What about scaffolding? Do I have to design scaffolding? What is a generally recognised standard configuration?

      • Answer. Most scaffolds can be erected following a generally recognised standard configuration. Such as those given in the National Access and Scaffolding Confederation (NASC) guide TG 20:08, or used in accordance with the manufacturers guidance for system scaffolds.

        Where scaffolds due to their complexity or size cannot be erected to these established configurations they should be designed generally in accordance to the principles given in BS EN 12811 or based on fundamental engineering principles. In these cases a note of the design should be available. Competent scaffolders should always erect tube and fitting, or system scaffolds, and a safe system of work should be followed, i.e. as described in NASC's guidance note SG4:05.
