The construction engineering market in France

According to Eurostat, France has 61,257 engineering and technical consultancy firms in 2024 (NACE 71.12), up from 52,794 in 2021, and they employ 306,214 people. On a wider scope, Syntec-Ingénierie, the trade federation, says it represents 80,000 outsourced industrial and construction engineering firms. Construction engineering in France remains fragmented: 80% of the 400 member firms of Syntec-Ingénierie are very small businesses or SMEs.

Demand for construction engineering in France follows building and public works activity. According to Eurostat’s production index, construction fell by about 3.5% in 2025 compared with 2024, with −5.7% for buildings and −2.3% for civil engineering (calculated from Eurostat). Major programmes support design offices: the Somme canal bridge on the Seine-Nord Europe canal is estimated at €440 million excluding VAT, according to Le Journal des entreprises, April 2026.

Construction engineering in France brings together large multidisciplinary groups, such as Egis, Artelia or Ingérop, and a broad network of independent design offices. Egis claims 23,500 employees in more than 70 countries; Artelia describes itself as one of Europe’s top ten construction engineering firms. According to Le Moniteur des travaux publics et du bâtiment, March 2026, Artelia is cutting its pay-rise budget to 2.7% of payroll, against 3.5% in 2025, and Ingérop plans 2.38%.

The RE2020 environmental regulation (the French building environmental standard) increases the study workload of construction engineering in France. According to La Gazette des communes, June 2026, an RE2020 study takes two to three times longer to prepare than an RT2012 study and can cost several tens of thousands of euros for a 60-place nursery. Since 1 May 2026, the RE2020 has applied to 13 new categories of buildings used by local authorities, including nurseries, Ehpad (care homes), media libraries and sports halls.

Artificial intelligence mainly changes the tasks of design offices in construction engineering in France, without replacing professional expertise. According to Le Moniteur des travaux publics et du bâtiment, May 2026, a Coface-OEM study ranks architecture and engineering among the professions most exposed to automation, at a level of 27%. Schools are adapting: ESITC Paris has created an AI and machine learning module in the fourth year, and École des Ponts ParisTech uses an AI engine that integrates regulations and the Batiprix database.

A PDF report in French, 2026 edition, organised in six chapters: scope and professions, market size and dynamics, client demand, supply and players, regulation and constraints, and outlook.

Eurostat statistics, Syntec-Ingénierie publications, information published by companies and trade press articles from the IndexPresse database. Every figure comes with its source and period.

Yes. The study is updated before it is sent, within 48 hours at most: it includes the latest published data, and every figure comes with its source and period.

Heads of design offices and engineering firms, public and private clients, construction companies, as well as consultants, bankers and investors who need to understand construction engineering in France.

By email, as a PDF, within 48 hours of payment. Our analysts use that time to add the latest available data before sending. You then find it in your My studies area.

A Google search or a general-purpose AI returns isolated figures, often with no date or precise scope, and cannot reach the professional press, largely behind paywalls. The study starts from a defined market, crosses public statistics with more than 500 trade journals from the IndexPresse database and links every figure to its original source. You get an up-to-date file you can cite and present as it is, without spending time cross-checking.

An invoice with VAT is emailed after every payment, and you can enter your company VAT number. For a quote, a purchase order or a bank transfer, contact us.
