About our structural calculations service in Causeway Coast and Glens

Structural calculations are an engineer's written design showing that a beam, column or other structural element can safely carry the loads placed on it. For steel beam work they set out the loads from floors, walls and roof, the steel section, the padstones or columns at each end and any propping requirements, and they are submitted to building control.

Structural calculations are one of the most common structural jobs in homes across Causeway Coast and Glens. Towns we cover include Ballycastle, Limavady and Coleraine, among other places in the area. Every job starts with a survey visit, then calculations from a structural engineer, so the steel suits the house in front of us rather than a rule of thumb.

Key points for your project

  • 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.
  • 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.
  • Opening up can reveal things no survey could see, such as a hidden chimney flue, joists running the other way or a wall with no footing. When that happens, the engineer revises the design before work continues, and any change is priced before it goes ahead.
  • 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 long calculations take depends on the engineer's workload and how complicated the job is. A single beam is quicker to design than a loft conversion with several steels, and any opening up needed for investigation adds time before figures can be issued.

How the job runs in Causeway Coast and Glens

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building control

    A full plans application or building notice goes to Causeway Coast and Glens Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Causeway Coast and Glens

Building control in Causeway Coast and Glens is run by Causeway Coast and Glens Borough Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.

The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Structural calculations in Causeway Coast and Glens: your questions

Can I stay at home while the work is done in Causeway Coast and Glens?

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 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.

Can I use calculations from my architect or previous builder?

Yes, as long as they match what is actually being built. We check the spans, loads and bearing details against the layout and the site before ordering steel. If the plans have changed since the calculations were done, or the site differs from what was assumed, the engineer needs to update them first.

What is a load take-down?

A load take-down is the part of the calculations that adds up every load reaching a beam or column and follows it down to the ground. It includes the roof, floors, walls, people, furniture and, where relevant, snow and wind. Each element along that path is then checked to make sure it can carry its share.

Can a builder size a steel beam without an engineer?

Not for building control purposes. Building control normally expects calculations from a qualified structural engineer showing the beam is adequate for the actual loads. Rules of thumb do not account for what sits above or how the ends are supported, which is why we always work from an engineer's design.
