RSJ installation in Dundee: how it works

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.

Homes across Dundee range from Victorian terraces to post-war semis and newer estates, and RSJ installation looks different in each. That covers every postcode district in the area. We plan the steel, the temporary support and the approvals around the building, then fix the price in writing once the scope is agreed.

Worth knowing before you start

  • 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.
  • 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.
  • Steel for internal use is normally delivered with a primer coat to protect it during installation. Beams in damp positions, within external walls or exposed outside need a more robust coating or galvanising, as the engineer specifies.
  • If you already hold calculations from an architect or engineer, we install to those. Where something on site differs from the drawing, such as a weaker wall or a different joist direction, the engineer is asked to confirm before work carries on.
  • Padstones spread the concentrated load from each beam end into the masonry below. They may be concrete, engineering brick or a steel plate, depending on the engineer's design and the strength of the wall beneath.

Four stages, one team

  1. Free visit

    A short visit to Dundee 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 warrant

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

  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.

Building rules for Dundee

Steel beam work in Dundee needs a building warrant from Dundee City Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Local questions answered

How much does RSJ installation cost in Dundee?

As a guide, budget £730–£2,280 per beam including VAT for rSJ supply and fit (single beam) in Dundee, based on published UK cost guides adjusted for prices in Scotland (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

Do I need a party wall agreement for RSJ installation in Dundee?

There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it 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.

Does an RSJ need to be painted or boxed in?

Usually it needs fire protection, most often by boxing in with fire-rated plasterboard and skimming. If you want the steel on show, an intumescent paint system can be applied to the specified thickness and then top-coated in your chosen colour. The fabrication primer is not fire protection on its own.

How is an RSJ installed?

The structure above is propped, the wall or opening is prepared, and padstones are bedded at each end. The beam is lifted onto them, bolted where needed and packed with shims and dry-pack. Props come out once it is carrying, building standards inspects it, and the steel is then fire protected and finished.

Can you fit an RSJ to my own engineer's calculations?

Yes. We install to calculations and drawings from your engineer or architect, as long as they cover the beam, bearings and any columns or connections. If site conditions differ from what the design assumed, we check with the engineer before carrying on.

Who approves RSJ installation in Dundee?

Structural work in Dundee needs a building warrant from Dundee 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.
