About our structural calculations service in Portslade

Need structural calculations in Portslade? Portslade is around 3.5 miles from Brighton, and we cover both. We survey the property, arrange the engineer's design, deal with Brighton & Hove City Council, fit the steel and make good, all under one quote for BN3 and BN41 addresses.

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

  • The cost of calculations rises with complexity: the number of beams and columns, whether loads come down from several floors, whether foundations need designing, and how much investigation is needed on site. A single straightforward beam sits at the simpler end.
  • 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.
  • 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.
  • 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 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.

How the job runs in Portslade

  1. Free visit

    A short visit to Portslade to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to Brighton & Hove City Council, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Portslade

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Brighton & Hove City Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Local questions answered

Do you cover Portslade for structural calculations?

Yes. We carry out structural calculations in Portslade and the BN3 and BN41 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 Portslade?

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.

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 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 you work on older or listed homes in Portslade?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
