RSJ Installation in Poole

Plan an RSJ or steel beam installation in Poole with the right site check, drawings, structural calculations, Building Control route and builder-ready scope before anyone cuts into a wall.

Short answer

You need the opening, beam, padstones, temporary support and Building Control route understood before the wall comes out. The expensive mistake is treating an RSJ like a simple builder task instead of a controlled structural alteration.

What's included

Clear route, no guesswork

  • Check the wall, span and load path before pricing the work
  • Define whether drawings or structural calculations are needed
  • Map the Building Control inspection and sign-off route
  • Plan temporary support, beam access and installation sequence
  • Turn the structural scope into builder-ready work
  • Connect the RSJ work to the wider kitchen or open-plan project where needed

How it works

The PlanBuild route

1

Send the wall and opening photos

Share the address, the wall you want opened, room photos and any drawings or engineer notes you already have.

2

Confirm the structural route

We identify the likely next step: site check, structural calculations, Building Control route, or the full knock-through scope needed to price the work.

3

Install from a controlled scope

The work is then planned around support, beam handling, inspection and making good instead of loose assumptions.
