About our structural calculations service in Barnstaple
We carry out structural calculations in Barnstaple, covering the EX31 and EX32 postcode districts. Our coverage runs across Devon, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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.
Key points for your project
- 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.
- A load take-down traces every weight that reaches the beam, from roof tiles and snow to upstairs walls, furniture and people. Getting this right matters as much as the beam choice itself, because an underestimated load makes every later check wrong.
- Strength is only half the design. The engineer also limits how much the beam bends under load, because excessive deflection cracks plaster, jams doors and can damage glazing. Wide glazed openings often need a stiffer beam than strength alone would suggest.
- Older buildings take more judgement. Lime mortar, rubble-filled walls, timber bressummers and shallow footings all affect how loads are carried, so engineers working on period properties often allow for weaker materials or ask for more investigation.
- Keep the final calculations and drawings with the building control completion certificate. Together they show a future buyer, lender or surveyor exactly what was installed and why, and they help any later alterations to build on a known design.
How the job runs in Barnstaple
Survey in Barnstaple
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 a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
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.

| RSJ supply and fit (single beam) | £820–£2,580 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
| Building control fees | £260–£670 | Building notice or full plans fee and inspections; varies by council or approver |
| Loft conversion steels | £2,600–£6,200 | Supply and fit of floor and ridge steels on padstones, including lifting into the roof space |

Building control and neighbours in Barnstaple
For Barnstaple, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about structural calculations in Barnstaple
Can I stay at home while the work is done in Barnstaple?
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.
Do you also work near Barnstaple?
Yes. We also cover nearby towns including Bideford.
Do structural calculations tell you which beam to buy?
Yes. The calculations specify the steel section, its grade and length, and the padstones or columns it needs, so the fabricator can supply exactly what was designed. Substituting a different beam on site without the engineer's agreement would leave the work out of line with the approved design.
How long do structural calculations take?
It varies with the engineer's workload and the complexity of the design, so there is no fixed turnaround. A single beam in a straightforward wall is usually quicker than a loft conversion or a frame with foundations. Any site investigation needed first, and any building control queries afterwards, add to the overall time.
Do I need calculations for an old beam when selling my house?
Often a buyer's surveyor or solicitor will ask for them if there is no record of the beam being approved. An engineer can inspect the existing steel, check it against the loads and issue calculations or a report. In England and Wales these can support a regularisation application for retrospective approval.
