  1. Question sent by David - is there any difference is design procedural scope between Permanent Works and Temporary Works engineers for building related construction (say residential housing or commercial high rise) and infrastructural works (say highways)? If there is, can you please outline the differences? Furthermore, is there a code or standard which can assist with this?
  2. Question sent by David - I was wondering if there exists a design procedural document (preferably Australian-related standards or others) which outlines the delineation of scope between Permanent Works and Temporary Works engineers. I am aware of Clause 8 in "BS 5975-2019 - CoP for Temporary Works", however unsure if there is a direct correlation to related practices within Australia

    Although written against UK legal requirements, there is much common ground with Australia. WEBINAR: https://www.ice.org.uk/events/designing-a-safer-built-environment-webinar Webinar Synopsis: It is crucial to improve design risk management (DRM) in civil and structural engineering. DRM can prevent accidents and reduce costs when the issues are dealt with at the design stage. This webinar will help designers to produce a design they can demonstrate could be built, used and maintained, without negatively affecting safety, health and wellbeing. Design risk management also helps to avoid unexpected costs and delays. Designers have faced long-standing uncertainties in the field of DRM. There has been no standardised way of approaching the issue, and it is still not fully understood. The Grenfell Tower fire has revealed deep-seated shortcomings applicable to all projects. By taking a pragmatic approach, DRM not only builds upon good engineering practice but also helps to provide long-term benefits for all parties involved. This webinar will explain how statutory obligations on designers can be delivered in the real world of commercial projects. The methodology to be outlined creates a logical framework, minimises paperwork, and maximises added value. It will not approach DRM in the usual fashion. The proposed methodology will be of relevance in many countries, adopting similar legislative approaches to the UK. If you are a designer, manage designers, a client or a contractor — you should book your place now. The webinar is based around the recently published book, Designing a Safer Built Environment: A complete guide to the management of design risk, on the same subject. Participants attending the live event will receive a 20% discount code they can use to order the book from ICE Bookshop.

    Temporary Works in the UK - 30 Years of Changes and Current Best Practice By Ray Filip In the UK how we manage the design and construction of temporary works has significantly changed over the last 30 years or so. This presentations discusses these changes and highlights some common issues and shows current UK best practice. Key Takeaways Changes in the field of temporary works Example of common temporary works issues UK temporary works best practice About the Speaker Ray is a chartered Civil Engineer and a Fellow of the Institution. He has been involved in the field of temporary works for nearly 35 years, having worked for major contractors in the UK and Southern Africa and a specialist UK subcontractor. For the last 14 years Ray has run his own temporary works consultancy, offering specialist technical advice, temporary works design, procedural control, site auditing and training. Since 2016 he has been on the British Standards committee responsible for revising BS5975. On occasion Ray also advise the UK Health and Safety Authority on temporary works issues
  5. Could you let us know the reference standards and regulations for design of riggings? What safety factor and deflection limit should be considered during the design (such as window /light weight rigging).
  6. What load factors are applicable to lifting equipment and lifting points? (dynamic factors, unequal load distribution factors, etc.)
  7. In the lift plan for the computer, are the shackles and padeyes in Detail A and B in the wrong orientation? It appears that slide loading will be applied to the padeyes.
  8. With the static loading (first) discussion, you mentioned a secondary pivot point of timber/rubber can be used if a suitable pivot point cannot be achieved. In this case, what is the process (if any) of sizing and positioning these secondary pivots?
  9. I struggle to control large reo cages when transferring from the tail lift crane to just the top lift. Any suggestions?
  10. Is there are maximum or minimum angle on the sling and spreader bar, or does it still follow A>B?
  11. Your sling force calculation showed a 32t live load on a spreader with unequal slings to calculate / determine size of a shackle; does the 32t weight need to factor in a FoS of 4, or is the FoS of 4 already taken into account of the rigging?
  12. What are the major risks involved in re-using temporary work structural on several projects?
  13. What are the legal responsibilities / liabilities for engineers in terms of temporary works? Especially if done by others at a site.
  14. What are your thoughts on contractors current tendency to have certified temporary works designs "independently reviewed" by another engineer
