The six fields
| Field | What it covers |
|---|---|
| Fire safety | minimum conditions of design and construction |
| Welfare at work | safety of workplaces and sites |
| Construction products | placing on the market and marking |
| Standardisation | status and publication of Belgian standards |
| Law of obligations | contracts, liability, compulsory insurance |
| Public procurement | award and execution |
Those six fields apply identically in the three regions, making them the common base on which a multi-region professional can rely.
Fire safety
This is the federal field that most shapes design. It concerns fire safety.
The minimum conditions to be met by the design, construction and fitting out of buildings are laid down by royal decree, on the basis of a 1979 act on the prevention of fires and explosions. Those conditions apply throughout the country.
Those basic standards pursue three objectives: preventing the outbreak, development and spread of fire and smoke, including to neighbouring buildings; ensuring the safety of persons through evacuation or rescue; enabling the fire services to intervene in good conditions.
One feature deserves noting: those basic standards are not standards in the technical sense but binding regulatory provisions. The vocabulary invites confusion, and the distinction is developed in the article on the status of a standard.
Their scope and exclusions are covered in the branch on fire safety. The categories are compared there.
Welfare at work
A field designers often neglect, and one that nonetheless applies. It concerns welfare at work.
Federal welfare-at-work rules impose requirements on workplaces, which sit alongside those of the building. They apply as soon as a building houses workers, covering nearly all non-residential briefs.
They also apply to the site itself, through safety and health coordination obligations, which makes this a real cost item, covered in the guide on construction costs per m².
Construction products
A field where the federal level mainly applies a European framework. It concerns construction products.
Placing construction products on the market falls under a regime harmonised at European level, transposed and applied federally. The declaration of performance follows from it.
The central mechanism is presumption of conformity: a product complying with a harmonised standard is presumed to meet the corresponding essential requirements.
That mechanism explains why product standards hold a particular place among the standards cited in specifications, as the guide on measurement and specification shows. Their reference is not merely contractual.
The law of obligations and liability
This is the field with the heaviest financial consequences. It concerns civil liability.
The liability regime of construction professionals, notably ten-year liability, belongs to civil law and hence to the federal level. The obligation to insure that liability likewise derives from a federal act.
Those rules therefore do not vary between regions, a welcome simplification, and they are covered in the article on good practice and liability.
The status of the architect's profession also attaches here, the mandatory nature of their involvement for works requiring consent deriving from federal legislation. Those rules apply irrespective of the region.
Public procurement
Public procurement rules are federal, even though most contracting authorities are regional or local. The distinction matters when a dispute arises.
That configuration explains a Belgian feature: the technical specification frameworks are regional, but the award and execution rules framing them are federal.
This point is developed in the guide on measurement and specification. The contractual documents are analysed there.
What this changes in practice
Three consequences for a professional.
The federal base transfers between regions. Expertise acquired on fire safety, products or liability holds across the territory.
Looking at the right level saves time. Fire safety requirements do not appear in regional planning codes, and looking there wastes effort.
Federal changes affect all projects simultaneously. An amendment to the basic fire safety standards applies everywhere on the same date, which simplifies monitoring compared with regional matters.
