Can steel portal frame building kits be supplied with an erection service?

Yes. An erection service means the steel portal frame kit is assembled on the prepared site by an installation team rather than being supplied solely for the client’s contractor to construct. The kit, design information and erection arrangement are treated as one coordinated building package, subject to the agreed project scope.

The process normally begins with confirming the building design and the information required for fabrication. For a bespoke portal frame building, this can include planning elevation drawings and isometric fabrication blueprints. These documents help establish the frame dimensions, member positions, connections and other details needed to manufacture and assemble the steelwork correctly.

Once the steelwork has been manufactured, the erection stage involves positioning and connecting the structural components in the sequence required by the design. The installation scope should be set out clearly before work begins, as a steel frame erection package may differ from a complete building installation. For example, the agreement should identify whether it covers:

• assembly of the main portal frames;
• installation of secondary steelwork, such as purlins and side rails;
• fitting of associated building components supplied within the package;
• use of lifting equipment and any requirements for access to the site; and
• work needed to complete the structure ready for subsequent trades.

The condition of the site is an important part of planning the erection work. The base and supporting works need to be prepared to the agreed design before the steel frame can be installed. Access for delivery and lifting equipment, suitable space for handling materials, and a clear understanding of site restrictions should also be considered. These matters can affect the installation method even where the steelwork design itself remains unchanged.

Choosing an erection service can be useful where the client does not want to appoint and coordinate a separate steelwork installer. It also gives the project a single point of coordination between the manufactured components, the design information and the physical assembly of the frame. Clients who already have suitable contractors can instead purchase the building kit for installation under their own arrangements.

Before placing an order, it is sensible to confirm exactly what is included in the erection quotation and what remains the client’s responsibility. Ask for the agreed building dimensions, design deliverables, installation boundaries, site preparation requirements and any exclusions to be recorded in writing. This is particularly important where the portal frame forms part of a larger agricultural, industrial or equestrian development involving cladding, doors, concrete work, services or internal fit-out.

Buildings UK Ltd can therefore provide the steel portal frame kit together with a full erection service, allowing the supply and assembly option to be considered alongside a kit-only purchase. The appropriate route depends on the client’s available contractors, site arrangements and the level of project coordination required.
