## Products & services

BAM’s named housing concept, Flow, is an off-site-produced timber home using prefabricated timber-frame and cross-laminated-timber (CLT) elements with circular, bio-based materials. BAM says the home shell can be assembled on site in a day; for a 2025 project, it reported an average construction process 75% faster than traditional methods. [8](https://www.bam.com/en/press/press-releases/2025/11/bam-begins-construction-of-76-flow-homes-at-wickevoort-estate-in)

Its construction and maintenance services include buildings such as homes, offices, schools and hospitals, as well as roads, bridges, locks, tunnels and rail connections. BAM also works on energy and water infrastructure, telecom networks, coastal defences and water-management schemes. [1](https://app.finbar.com/go?id=P87738850)[2](https://www.bam.com/en/about-bam/organisation) The company provides circularity assessments and material passports to evaluate and document materials, supporting repair, disassembly, reuse and recycling; in 2025, it offered these tools in 69% of large tenders with design in scope.

## Geographic presence

BAM’s main geographic operating divisions are the Netherlands—which also includes its Denmark activities—and the United Kingdom & Ireland. Belgium, Germany and International are monitored together as a non-reportable segment, so the available reporting does not provide separate revenue figures for those countries. BAM also identifies the Netherlands, Belgium, the UK, Ireland and Germany as home markets. [11](https://app.finbar.com/go?id=P54890516)[12](https://www.bamcareers.com/global/en/campaigns-our-bam-locations)

For 2025, revenue was €3,487 million for the Netherlands division (49.5% of group revenue), €3,433 million for UK & Ireland (48.8%), and €120 million for Germany, Belgium & International (1.7%), out of €7,040 million total. Percentages are calculated from reported division and group figures; the Netherlands figure includes Denmark and is not a country-only amount. [4](https://app.finbar.com/go?id=T10924539)

At year-end 2025, BAM reported 14,167 employees: 7,019 in the Netherlands division (49.5%), 6,845 in UK & Ireland (48.3%), and 303 in Other (2.1%). These are division-level figures, not a country-by-country employee distribution. [5](https://app.finbar.com/go?id=T8156006) BAM identifies Bunnik in the Netherlands as its head-office location and provides an office finder searchable by division, city and country.

## Business segments

For FY2025, BAM reported Division Netherlands and Division United Kingdom and Ireland (UK&I) as its reportable segments. Germany, Belgium and International were combined because they were not individually reportable; Invesis was reportable only until its divestment in Q1 2025. [11](https://app.finbar.com/go?id=P54890516)

Division Netherlands generated €3,487 million, approximately 49.5% of group revenue. Its principal reported business lines were construction and property (€2,399 million) and civil engineering (€1,126 million); the division also includes BAM’s Danish activities. The report describes its focus as cost efficiency in residential construction, selectivity in non-residential work and civil engineering projects contributing to sustainability. [4](https://app.finbar.com/go?id=T10924539)[15](https://app.finbar.com/go?id=T5750279)[16](https://app.finbar.com/go?id=P58152817) UK&I generated €3,433 million, approximately 48.8%, with revenue reported across UK construction (€1,120 million), UK civil engineering (€1,777 million) and Ireland (€603 million). The combined Germany, Belgium and International category contributed €120 million, approximately 1.7%. Shares are approximate calculations using the reported group revenue of €7,040 million.

## Company history

BAM traces its origins to 12 May 1869, when Adam van der Wal opened a carpentry business in Groot-Ammers. In 1927, the business became a public limited company named Bataafsche Aanneming Maatschappij, and it was listed on the Amsterdam Stock Exchange in 1959. The company dates the start of its international construction business to 1958. [19](https://www.bam.com/en/about-bam/history)[20](https://www.bam.com/en/press/press-releases/2018/10/bam-international-celebrates-60-years-of-worldwide-construction)

BAM expanded through major acquisitions, including the 1988 acquisition of the operational division of Verenigde Bedrijven Bredero and the 2000 transfer of NBM-Amstelland’s construction and infrastructure activities. After acquiring HBG in 2002, the company launched Royal BAM Group. [21](https://www.bam.com/nl/pers/persberichten/1988/8/persbericht)[22](https://www.bam.com/nl/pers/persberichten/2000/11/bouwactiviteiten-nbm-amstelland-overgedragen-aan-koninklijke-bam-groep)[23](https://www.bam.com/en/press/press-releases/2002/11/royal-bam-group-launched) Ruud Joosten became CEO and Executive Board chairman in September 2020, succeeding Rob van Wingerden. [24](https://app.finbar.com/go?id=P33448783) BAM completed the sale of its remaining 50% stake in Invesis to PGGM in March 2025.
