Scaffolding is not a new phenomenon. For as long as building has taken place at heights, craftspeople have needed a temporary platform to work from. In recent times, the Danish scaffolding trade has moved from a loosely defined craft practice — loose pipes, boards and couplings assembled according to experience — to a regulated trade with European standards, legally required training and documented inspections. This article focuses on the development we can document; older, local guild rules are mentioned only generically, because they are difficult to verify.
Introduction
Scaffolding has always been a prerequisite for building — the temporary working platform that all other trades stand on. The path from the craft's loose pipes and boards to today's standardised system scaffolding has gone through standardisation, legal requirements for training and a consolidation of the Working Environment Authority's regulations. Here are the main points, with emphasis on the facts we can document.
From wood and pipe to system scaffolding
Historically, scaffolding was erected from the material at hand — first wood, later steel pipes assembled with couplers. The pipe-and-coupling method, where loose steel pipes are clamped together with clamps, is still used today for special constructions, precisely because it can be adapted to any geometry. In the course of the 1900s the prefabricated systems came: ready-made steel frames and later modular systems with fixed nodes that click together according to standard sizes. This made the scaffold faster to erect and easier to document.
Europæisk standardisering: EN 12810, EN 12811 og EN 1004
The most important change in recent times is European standardization. Today the design of work platforms is based on a set of common European standards which have been adopted as Danish (DS/EN). These standards define load classes width classes railing requirements and material specifications — and which the entire calculator part of this site is built on.
- 01DS/EN 12811-1 — requirements for performance and general design of work platforms (load classes 1–6, width classes W06–W24, railings).
- 02DS/EN 12811-2 — material specifications for work platform components (basis for disposal assessment).
- 03DS/EN 12810 — facade scaffolding made of prefabricated components (frame scaffolding).
- 04DS/EN 1004 — rolling scaffold (mobile work towers) with their own height limits.
Common standards mean that an installer in Denmark sizes according to the same classes as colleagues in the rest of the EU, and that a certified component can be documented across borders. Note, however, that the exact capacity figures for columns and beams remain supplier-specific and are found in the system documentation — the standard sets the framework, not the individual product's numbers.
Statutory training for scaffolding erectors
One of the most marked features in the development of the Danish scaffolding trade is the requirement for education. Today anyone who needs to erect change or dismantle scaffolding higher than 3 metres must have completed the special legally required education for scaffold erectors. The education is typically taken via AMU often while already working at a scaffolding company. The requirement is anchored in a regulation on work environment professional education (BEK no. 1978/2021 Annex 11 amended by BEK no. 728/2024).
