Planning RSJ installation in Glasgow

RSJ installation is the supply and fitting of a structural steel beam to carry load across an opening or in place of a wall. RSJ stands for rolled steel joist, an older name for an I-shaped steel section; most domestic beams today are universal beams. Installation covers fabrication to the engineer's design, delivery, lifting, bedding on padstones and packing tight.

From the first survey visit to the completion certificate, we take care of RSJ installation across Glasgow. That covers every postcode district in the area. The engineer sizes the steel, we deal with Glasgow City Council, and our team fits and packs the beam before making good.

Worth knowing before you start

  • Sometimes two beams are bolted side by side with spacers, either to carry a thick wall or to fit through a tight space. Bolt spacing and spacer type come from the engineer's design rather than being decided on site.
  • Where a long beam cannot be carried into a property in one piece, the engineer can design a bolted splice so it arrives in two or more lengths. The splice position and bolts are part of the calculations and must be installed exactly as drawn.
  • Floor joists can rest on the bottom flange, hang from timber packers bolted into the web, or be notched to sit over the steel. The engineer specifies the connection, and it affects how flush the finished ceiling can be.
  • Packing is what makes the beam work. Steel shims and dry-pack mortar fill the gap between the top flange and the structure above, so the load transfers onto the steel without the floor or wall settling down onto it.
  • Delivery can make or break an RSJ job. A long beam has to turn through a front door, along a hallway and past the stairs, so routes are measured at the survey and alternatives such as a window opening are planned early.

What happens, step by step

  1. Survey in Glasgow

    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.

  2. 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.

  3. Building warrant

    A building warrant is applied for from Glasgow City Council, and work starts only once the warrant has been granted.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building standards inspects it, and we make good.

What does RSJ installation cost in Glasgow?

As a guide, budget £730–£2,280 per beam including VAT for rSJ supply and fit (single beam) in Glasgow, based on published UK cost guides adjusted for prices in Scotland (-9%).

JobTypical guide rangeWhat it usually covers
RSJ supply and fit (single beam)£730–£2,280 per beamBeam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately)
Temporary works and propping£140–£460Props, spreaders, needles and sole plates for a typical opening, installed and struck
Load-bearing wall removal with steel beam£1,800–£4,550Typical internal wall up to about 4 m: calculations, building standards, propping, steel, padstones, fitting, fire protection and making good
Fire protection to a steel beam£140–£550 per beamFire-rated board boxing or an intumescent coating system as specified

Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.

Building control and neighbours in Glasgow

Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to Glasgow City Council. The finished work is then certified and a completion certificate submitted for acceptance.

There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

Questions about RSJ installation in Glasgow

Who approves RSJ installation in Glasgow?

Structural work in Glasgow needs a building warrant from Glasgow City Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

Do you cover Glasgow for RSJ installation?

Yes. We carry out RSJ installation in Glasgow. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

What is included in an RSJ supply and fit price?

Our itemised written quote sets out the calculations, building standards, steel and fabrication, delivery, lifting, padstones, propping, labour, fire protection and making good as separate lines. Once the specification and scope are agreed, the price is fixed in writing, so you know the full cost before work starts.

Can an RSJ be delivered in sections?

Yes, where access is tight. The engineer can design bolted splice joints so a long beam arrives in two or more pieces and is joined in place. The splice has to be part of the calculations from the start, because it changes how the beam carries load at that point.

How heavy is an RSJ and how is it lifted?

Weight varies widely with the section and length, from beams a small team can carry to steels needing mechanical lifting. The lift is planned at the survey, using enough people, trolleys and suitable lifting equipment so the beam goes up safely and level onto both bearings.

What does RSJ stand for?

RSJ stands for rolled steel joist. It was the name for a hot-rolled I-shaped steel section with tapered flanges, and it is still used loosely for any steel beam in a house. Most steels fitted in homes today are universal beams, which do the same job with parallel flanges.

Can you work on older or listed homes in Glasgow?

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.
