Firms operating in Europe that supply engineering services for construction and the built environment
EFCA Sector Review 2022 PDF
EFCA Sector Review 2023 Survey (ends 31 October 2023)
Listed below is the country in Europe (as defined by EFCA for the EFCA Sector Review Survey) in which companies and groups are based that operate in Europe and supply engineering services for construction and the built environment in more than one country.
Firms with a headcount of more than about 200 staff based in Europe are assigned to:
- the country where a firm is based, for firms based in Europe and operating in more than one country in Europe;
- the country with the most operational capacity or control, for firms based outside Europe.
Listed are:
- in square brackets, the number of countries in Europe in which a firm has a permanent presence;
- the approximate global headcount at the end of 2022.
For the survey, any follow-up with firms based both inside and outside Europe is carried out by the EFCA Survey Coordinator.
The list aims to ensure that groups operating in more than one country in Europe will be approached through a single point of contact. It is organised by country and by the name of the firm.
Comments or adjustments (to the EFCA Survey Coordinator - peter@peterboswell.com) are very welcome.
