The construction sector accounts for nearly 9% of Belgian GDP and employs over 300,000 people. In an officially trilingual country, public procurement documents, building permits, and technical specifications must be available in French, Dutch, and sometimes German - making construction translation a strategic necessity for any international engineering firm or contractor.
Construction Documents That Require Translation
Belgian construction projects generate extensive documentation from the very first stages: architectural plans, building permits, structural calculation notes, material data sheets, and CE conformity certificates. Whenever a foreign firm or non-French-speaking subcontractor is involved, every document must be translated with precision to avoid costly on-site disputes.
- Building permits and planning permits: URBAN application forms and files submitted to Walloon, Flemish, or Brussels Region municipal authorities
- Specifications (CSC/BBB): administrative and technical clauses, summary schedules of quantities, key documents for public tenders
- Technical plans and calculation notes: translation of legends, material specifications, and reference standards
- NBN and EN standards: translation of applicable normative requirements (thermal insulation, fire safety, accessibility for disabled persons)
- Construction contracts and addenda: legal translation for temporary joint ventures (GME) and international consortia
- Expert reports and acceptance records: documents required during provisional or final acceptance of a structure
Public Procurement and NBN/EN Standards
Belgium applies EU Directives 2014/24/EU and 2014/25/EU on public procurement. Every tender submission must be written in the language of the relevant administrative region. A Dutch-speaking contractor bidding in Wallonia must submit its entire offer in French; a Parisian firm responding to a Flemish contract must produce its documents in Dutch.
NBN standards (Belgian Standards Bureau) are often transpositions of European EN standards but may include specific national annexes. Translating these normative references requires highly specialised technical expertise: an error in translating a strength class or a performance requirement can engage the ten-year liability of the project manager.

Rates and Turnaround Times
The rate for a technical construction translation depends on the volume, terminological density, and language pair. As a guide, a 20-page specification is priced from €250. A standard building permit (5-8 pages) starts at €80. For urgent projects, a 24h express option is available at a 30% surcharge.
TranslateBE works with translators who specialise in civil engineering, architecture, and Belgian construction law. Our translators are fluent in the terminology of NBN EN standards and standard specification documents (CCT Qualiroute, CCT Bâtiments). All translated documents are reviewed by a second expert before delivery.
FAQ
Frequently asked questions
Is a certified translation required for a building permit in Belgium?
For a building permit submitted to a Belgian municipality, a translation certified by a sworn translator registered with the SPF Justice is recommended when the original documents are in a foreign language (English, German, Dutch outside the region). Some municipalities require it explicitly; others accept a signed technical translation. We recommend checking with the relevant planning department before placing your order.
Can a technical specification be translated within 24 hours?
Yes, for volumes up to 15 pages our 24h express service is available Monday to Friday. Beyond that, we mobilise a team of translators working in parallel to meet the deadline. The express translation carries a 30% surcharge on the standard rate. Send your document this evening and we will acknowledge receipt and confirm the turnaround within the hour.
Which languages do you cover for construction documents in Belgium?
We cover all language pairs relevant to the Belgian construction sector: French to/from Dutch, French to/from English, French to/from German, Dutch to/from English, and other languages on request (Spanish, Polish, Romanian - languages frequently encountered in subcontracting contexts). As Belgium is trilingual, we work in all three linguistic regions.
