We knocked through the kitchen and dining room in our Woolton semi. The RSJ design was delivered fast and passed Building Control straight away.

I needed steel calculations for a rear extension in Crosby. The engineer specified the beams clearly and the builder had no issues following the plans.

Used them for loft conversion steelwork in Wavertree. The calculations covered the ridge beam and floor supports perfectly. Very professional service.

Common questions
Answers to frequent queries about RSJ design Liverpool and structural calculations.
How quickly can you turn around RSJ design in Liverpool?
For standard wall removals, we typically deliver the calculation pack within 24 to 72 hours of receiving all details. Larger projects like extensions may take slightly longer.
Will Building Control accept these calculations?
Yes. Our structural calculations comply with all relevant UK building codes and are presented in a format that Liverpool Building Control inspectors expect.
Do I need an architect before contacting you?
Not necessarily. For simple beam installations, we can often work from your own sketches and photos. For larger extensions, architect plans are helpful but not always mandatory.
Can you work without a site visit?
Yes, many domestic steel beam designs can be completed remotely using photos, plans and measurements. If a site visit is essential due to complexity, we will let you know.
