Anchors are a small component to which little consideration is frequently given but are absolutely vital to preventing the collapse of the structure or installation that depends on them. As the construction & M&E industry moves towards a compliant, tested, and traceable future, anchor/fixing compliance is critical. The contractors that follow guidance will no doubt lead the way and win the biggest projects.
BS 8539 is quite clear: the specified anchor must arrive on-site. Within the M&E industry anchors are usually left to the last minute and resulting in a higher risk of the specified anchor not arriving on-site.
In our latest sound out episode our anchor expert Stevan discusses the importance of supplying the specified anchor on-site.
To supply the specified anchor on-site, the manufacturer and their agents should provide:
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.
According to BS 8539 whoever has decided to select a different anchor is now the specifier and as such are liable.
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:
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.
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.
When selecting an anchor the following factors must be considered -
Anchor/fixing compliance for safe selection and installation doesn't have to be complex.
Did you know the Construction Fixing Association provides helpful guidance in relation to BS 8539.
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.
Here is an example of anchor installation failure. It reminds us of the importance of ensuring that all anchors specified are taken through the correct selection procedure as outlined in BS 8539.
