How can installers be trained to become BS 8539 compliant?

How is an anchor supplied on-site in accordance to BS8539? 

In our latest soundout episode our anchor expert Steve discusses the importance of supplying the specified anchor on-site. 

According to BS 8539 what information should be supplied to the supplier?

To supply the specified anchor on-site, the manufacturer and their agents should provide: 

  • All information for the specifier to select the correct anchor, having followed the correct selection criteria. 
  • Technical catalogues and software 
  • Installation instructions for the installer 

Under BS 8539 what is the supplier’s responsibility? 

  • Must provide the anchor as specified unless a specific change management procedure has been followed. 
  • They should take the opportunity to ensure all associated setting equipment is offered to the contractor such as drill bits, hole cleaning equipment, setting tools, torque wrench etc., in order that the installer can install anchors correctly 
  • Provide installation training or facilitate this being provided by the manufacturer. 
  • Provide guidance in anchor selection. 
  • Ensure the change management procedure is adhered to if asked for alternatives. 

Why would the specified anchor not arrive on-site?

Issues can often crop up between selecting the anchor and supplying that anchor on-site. Often a third party has been involved in the process and due to commercial reasons or supply issues (due to not enough time being allocated to follow the correct selection procedure) another anchor arrives on-site.  

Does this mean another stakeholder is liable?

According to BS 8539 whoever has decided to select a different anchor is now the specifier and as such are liable. 

If the new anchor has similar characteristics, then what is the issue?

We need to ensure that the anchor that has been specified (that product code) reaches the site. Breaking the spec of an achor can be a serious issue, for one the installer on-site may not know how to install the new anchor correctly. It is important to know that not all anchors are the same, a few typical differences between one anchor and another include: 

  • Different manufacturing references 
  • Unique performance characteristics 
  • Manufactured differently with specific load characteristics 
  • Installation instructions 
  • Approvals may differ 

How does BS 8539 guide us if the original specified anchor is not supplied on-site?

BS 8539 states ‘the correct anchor must be sourced as specified. If an alternative anchor is proposed, the change management procedure (clause 10) must be followed 

 If the contractor is aware of the anchor change, then they must inform the original specifier and ensure it is installed on-site to the manufacturer’s specification. 

BS 8539 and the change management procedure

As outlined in BS 8539 the change management procedure must be followed, but what is it? 

The change management procedure is referring to clause 10 of BS 8539 guide which states that the correct anchor selection process must be followed. 

According to BS 8539 how do I select an anchor? 

When selecting an anchor the following factors must be considered –   

  • Substrate – the manufacturer should advise what substrate is suitable for that anchore.g. cracked or non-cracked concrete. 
  • Loadings – what load can the fixing take and can the fixing perform to the load requirement? Once again, this would be outlined by the ETA. 
  • Environment – is it a corrosive environment? 
  • Type of install – is it going to be a through fix or a flush fix? 
Supplying the correct anchor on-site is important. 

To conclude supplying the correct anchor on-site reduces the risk of on-site anchor installation failure causing an increase in costs and potential missing project deadlines.
