The scaffolding reference work: the rules, the load classes, the erection and the safety — explained so it can be used on site.
A trade with height, freedom and a future
The scaffolder builds the workplace that every other tradesperson stands on. It's a trade with fresh air, good camaraderie within the crew and a low barrier to getting started — and at the same time a trade with responsibility, because safety rests on the scaffold being erected correctly. Here's why you should consider it.
Façade, modular, tube-and-coupler and mobile — what is used when
There isn't one scaffold, but a handful of systems, each solving its own task. The choice depends on the shape of the building, how high you need to go, how much has to be carried, and how quickly it has to happen. Here are the types you'll meet in practice — and when to choose which.
How to dimension scaffolding to EN 12811
How much may a scaffold deck carry, and how wide must it be? This is determined by two things from the standard DS/EN 12811-1: the load class, which sets the permitted weight per m², and the width class, which sets the deck's width. Here are both tables — and how to choose correctly for the task.
Temporary work platforms in building and civil engineering
A scaffold is a temporary structure that provides safe access and a safe working platform at height. Here are the main components, the uses — and why the field is so heavily regulated.
Arbejdstilsynet's requirements for erection, use and dismantling
The Danish regulatory basis for scaffolding: the construction-site order, the rules on technical aids and the Danish Working Environment Authority's guidelines — plus the responsibilities of the employer and the erector.
Standards, ledgers, braces, boards and guardrails — the parts and their dimensions
The individual parts of the scaffold with the correct Danish trade terms: standards/spigots, ledgers and transoms, diagonal braces, platforms, brackets, base jacks and ties — and what each of them does.
Safe work sequence from foundation to dismantling
The safe sequence for erecting and dismantling a system scaffold within the supplier's instructions — from the base and base jacks to progressive ties, guardrails and dismantling in reverse order.
Collective protection first — personal equipment as the last resort
The order of priority between collective and personal fall protection when working at height, and the requirements for the equipment. As a rule, protection against falls is required for falls of more than 2 metres.
The geometric safety requirements for the working platform
The requirements for how the guardrail is built up (handrail, mid-rail, toe board), when an inner guardrail is required, and how large the gap between deck and façade may be.
How to secure scaffolding against overturning and wind load
The function of the anchoring, the types of wall tie, and how the anchoring force and pattern depend on the sheeting, height and load — and why netting and tarpaulin increase the forces significantly.
Safe climbing up and down the scaffold
The requirements for access routes on and to the scaffold — stairs, ladders and internal ascent via hatch decks — so you can get safely up and down throughout the period of use.
Implications for load, anchoring and winter work
How sheeting with netting or tarpaulin increases the wind load and thereby the anchoring forces, when winter sheeting is required, and why stability must be recalculated when the sheeting changes.
Green and red scaffold tags — approval and inspection
Signage on scaffolds over 2 metres and ongoing inspection: what a green (ready for use) and a red (out of service) sign mean, what the sign must state, and when inspection is required.
Erector, supplier, user, designer and client
Who is responsible for the scaffold being safely set up and used? From the scaffold erector and the supplier to the user's employer and the client.
Legally required conditions, AMU courses and the 2-year programme
The statutory training requirements for erecting scaffolding and the available course paths — correcting the widespread ‘3-day’ misconception: the system-scaffolding course is 15 days.
Hvad erstatter B.3.2 — og hvad ændrer sig for stilladsopstilleren?
Fra den 15. december 2025 og 1. januar 2026 trådte en ny, konsolideret AT-vejledning om bygge- og anlægsarbejde i kraft. Den erstatter bl.a. den gamle AT-vejledning B.3.2 om opstilling og brug af stilladser. Her er, hvad du som stilladsopstiller skal vide om ændringerne.
Lastklasse 4, 5 og 6 — beregning af delareal og tilladt koncentreret last
Tunge lastklasser (4–6) giver mulighed for et forhøjet delareal, der kan bære langt mere end den jævnt fordelte last antyder. Men der er en formel for det — og den skal man kende, for ikke at overbelaste eller undervurdere stilladset. Her er princippet med et gennemregnet eksempel.
Sådan vurderer du om stilladskomponenter må bruges eller skal ud
Hvert enkelt stilladskomponent bærer sin del af den samlede konstruktion. En revnet søjle, en deformeret bjælke eller et halvt fortæret stilladsplanke kan koste liv. Her er kriterierne for at kassere komponenter — og kulturen for at gøre det konsekvent.
Fra håndværkets midlertidige stillads til normeret og certificeret fag
Stillads har altid været en forudsætning for byggeriet — den midlertidige arbejdsplatform, alle andre fag står på. Vejen fra håndværkets løse rør og brædder til nutidens normerede systemstillads er gået gennem standardisering, lovkrav om uddannelse og en konsolidering af Arbejdstilsynets regler. Her er hovedtrækkene, med vægt på de fakta vi kan dokumentere.
