About our structural calculations service in Bala
Structural calculations in Bala are planned around the house, not a standard kit. Our coverage runs across Gwynedd, so nearby villages are included too. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.
Building control will not approve a beam on trust. Before steel goes in, someone has to show in writing what the beam is carrying, what size it needs to be and how its ends are supported. That is the job of structural calculations, prepared by a qualified structural engineer from measurements taken at the property.
Worth knowing before you start
- Accurate site information is essential. The engineer needs real spans, joist directions, wall build-ups and what sits above, so a site visit or detailed survey usually comes before any calculations. Guesswork from estate agent floor plans is not enough.
- If you already have calculations from your own engineer or architect, we can work to them, provided they match the layout being built. We check that the spans, loads and bearings shown agree with what is on site before ordering steel.
- Calculations can also cover how the structure is held up during the work. For straightforward openings this may be a note on prop positions, while larger or more complex jobs may need a separate temporary works design.
- The beam ends are designed as carefully as the beam. Calculations check that the masonry under each end can take the concentrated load, and specify a padstone, spreader or column where it cannot. Weak brickwork beneath a bearing is a common reason for design changes.
- A typical calculation pack covers the loads assumed, the beam section chosen, checks for bending, shear and deflection, the bearing and padstone design, and any column or foundation design. It is usually accompanied by a drawing or sketch showing positions.
What happens, step by step
Survey in Bala
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit the application or notice to Cyngor Gwynedd under the Building Regulations as they apply in Wales, before work starts.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

| Load-bearing wall removal with steel beam | £1,800–£4,550 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Temporary works and propping | £140–£460 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |

Building rules for Bala
Welsh building regulations treat beams and new openings as controlled building work. We apply to Cyngor Gwynedd on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Structural calculations in Bala: your questions
Do you cover Bala for structural calculations?
Yes. We carry out structural calculations in Bala and the LL23 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can I stay at home while the work is done in Bala?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
What do structural calculations for a steel beam include?
They include the loads the beam carries, the steel section chosen, checks for bending, shear and deflection, and the design of the padstones or columns at each end. Most packs also come with a drawing or sketch showing positions and bearing details, and note the fire protection and any propping requirements.
What happens if building control questions the calculations?
The engineer answers the query, usually by providing extra checks, clarifying an assumption or adjusting the design. This is a normal part of the approval process and does not mean anything is wrong. Work on the affected element waits until building control is satisfied, and any design change that affects cost is priced before it goes ahead.
Do I need structural calculations to remove a wall?
Yes, if the wall is load-bearing. Building control needs calculations showing that the new beam, its bearings and anything supporting it can carry the loads safely. Non-structural stud partitions normally do not need them, but an engineer should confirm a wall is non-structural before anyone assumes it.
