Re: "Hoardings – A guide to good practice” (TWf2012: 01, August 2020)

The Temporary Works Forum (TWf) has revised “Hoardings – A guide to good practice” (TWf2012: 01, August 2020) 

Synopsis 

Site hoardings are common features, particularly in populated areas. However, despite their temporary and incidental nature they are important structures, often of some height, and attracting significant loads. They have been known to collapse and cause both death and injury. 

This guidance note is written to assist all parties involved in construction understand the key issues, and to give specific assistance to those specifying, managing, designing and installing these structures. 

Hoarding design can be complex and needs engineering judgement. The designer should have a level of competence commensurate with the complexity. All hoarding designs should be independently checked. 

Main changes 

The main changes made in this guide are:

  • References updated.
  • Updated to take into account CDM2015 and BS 5975: 2019.
  • Some notes added on the consideration of hoarding duration, shielding factors, wind effects around tall buildings.
  • Reduction of passive resistance due to slopes near to post-in-hole hoarding foundations.
  • Notes added regarding the use of fixing anchors for hoarding foundations.
  • Updated wind probability factor and factors of safety (and example calculation revised accordingly).
  • Added: Appendix F (Worked Example - Reduction of passive resistance due to sloping ground) and Appendix G (Worked example of concrete kentledge block foundation).
