A bit random, but worth a punt!

Purposefully a fairly generic question, and in the pre-check, give it a punt on Arbtalk to see if anyone has any sage words of wisdom before taking to Google in anger tomorrow, and mindful that all opinions, expressions and comments are purely 'conversational contributions' rather than declarations of professional opinion which might be relied or acted upon....

 

Scenario:

 

A structure (multi use sports ground fencing) is installed to a height of 3m in 2012 and at that time it complied with relevant British Standards.

 

15 years later there is a desire to enhance said structure - height extension by 2.2m.

 

If the standard that was relevant 2012 had been updated by 2017 I'm expecting that it would be a requirement for the original structure to be upgraded to 2017 spec prior to adding an extension which would be required to satisfy standard relevant in 2017?

 

Also, prior to having a check, I'm expecting that planning consent might be required?

 

Any takers??

Ok I will have a go

The structure will require planning it's over 2m tall

The up grade will be required to conform but the post were not designed for the load so demolish and start again

[donnk]

would have required planning at the time for 3m. So may be in place already, check.

 

Ask the fence manufacturer if it can be increased in height, maybe you need deeper footing etc.

 

There are no standards police so you can safely ignore that nonsense.

[kevinjohnsonmbe]

That's exactly in line with my thinking Donnk!!

 

👍🏻

 

I'll elaborate a bit for context later...

You must be really bored ! Do you fancy a day in pest Control ! Do you a swap you do my job I'd do yours for a day !

[dumper]

It will require planning as it is an increase in height

[Khriss]

..plus full structural engineers design as its supporting a load K ( Sorry )

[eagleye]

Extend it up with ball stop netting nice and light hardly any wind resistance

you might have to upgrade corner posts for straining wires and extend the others as intermediate supports

job done

Standards are not applied backwards, so a change in standard after 2012 won't need to be applied to the existing structue. However the part that is being upgraded will need to comply with the latest standards.

The circumstance leading to the original question has now passed (in quite a petulant and drama queen fashion with the resignation of the bloke driving the project) and is now likely to be subject to a more comprehensive and appropriate design and planning process. Essentially, the quick-fix bodge job that was being proposed was scuppered by the injection of logic which provided the revelation that a planning app would be required.

 

Happy, as above, that later standards don't apply retrospectively to existing structures - that might be considered as inappropriate and unworkable (residents of tower blocks may disagree 🤔)

 

But, if making a significant addition / adjustment to an existing structure, would it not be wise / required to bring the existing structure up to current spec prior to adding additional stress / load?
