In Belgium, public procurement represents a development lever often underutilized by small construction businesses. Yet, public authorities – municipalities, CPAS, intermunicipalities, schools, or hospitals – commission hundreds of construction sites each year: renovation of school buildings, insulation of social housing, roadworks, urban developments…

For tradespeople, subcontractors, and SMEs in the construction sector, this is a real opportunity to fill their schedules with stable, often well-paid projects. However, it is essential to understand the rules of the game and know how to position oneself. ArtiBox guides you to take advantage of these public calls for tenders and integrate this source of business into your strategy.

Local public contracts: a wealth of nearby construction sites

Every public entity in Belgium (city, municipality, province, intermunicipality…) can publish a public contract for construction, renovation, or maintenance work. These projects may involve:

  • thermal renovation of schools or town halls,
  • maintenance of administrative buildings,
  • repair of roads and sidewalks,
  • extension or upgrading of daycare centers and sports facilities,
  • energy renovation of social housing, etc.

Many of these contracts are segmented into small technical lots (carpentry, masonry, heating, electricity...), accessible to independent contractors and SMEs in the construction sector. The key is to be reactive… and well-prepared.

Construction SMEs: why should you be interested in public contracts?

Long perceived as complex or reserved for large companies, public contracts are evolving. In 2025, Belgian authorities increasingly encourage the participation of local micro and small enterprises in their calls for tenders, particularly to:

  • diversify service providers,
  • stimulate the regional economy,
  • promote short supply chains and local employment.

The result: specifications often include a clause allowing smaller companies to act as subcontractors, or to apply for contracts below a certain threshold (often below €140,000 excluding VAT).

These contracts are generally reliable in terms of payment and offer long-term visibility. Perfect for smoothing out activity between two private construction sites.

How to access public construction contracts in Belgium?

The official site e-Procurement centralizes the majority of public calls for tenders. You can:

  • create a business account,
  • set up alerts based on your specialties (plumbing, insulation, painting, etc.),
  • download specifications,
  • submit your application online.

For smaller construction sites, do not hesitate to contact the municipal technical services or the intermunicipal authorities in your province directly. Some contracts in negotiated procedures without publication can be awarded to known and reliable local companies.

Subcontracting: a good way to enter the circuit

If you do not wish to handle the administrative part or if your structure is too small to apply alone, you can easily join a group or a subcontracting network.

On ArtiBox, many general building companies holding public contracts are looking for partners to carry out specific parts of the work. This allows you to:

  • position yourself on public construction sites without responding directly to the call for tenders,
  • work in collaboration with reliable clients,
  • strengthen your order book without prospecting.

As a tradesperson registered on ArtiBox, you are connected with these companies as soon as a need arises in your region.

Tips for better responding to a contract or collaborating with a contractor

Here are some recommendations to increase your chances:

  • Structure your professional documents (insurance, ONSS certificates, references) to be ready to respond quickly.
  • Highlight your achievements by presenting them clearly (photos, type of construction site, materials used).
  • Work on your responsiveness: awarded companies often select the most organized and available subcontractors.
  • Register on ArtiBox to be visible to partners who already have public contracts to execute.
