Oosterhoff Acquires MJb groep to Expand Construction Management Services

Oosterhoff, a leading consulting and engineering group, has acquired MJb groep | Bouwregisseurs, a collective of construction directors specializing in complex projects. This acquisition marks MJb’s integration as the fifteenth company within Oosterhoff’s expanding ecosystem of advisory and engineering firms.

While financial terms of the transaction remain undisclosed, the deal involves a minority stake acquisition, with Arpentus Corporate Finance advising MJb’s representatives Jo Mans and Bert Jeurissen throughout the process. The partnership aims to combine MJb’s construction management expertise with Oosterhoff’s broad engineering and consulting services.

MJb groep is known for its technical proficiency and architectural sensitivity, translating ambitious project visions into precise, high-quality realizations. The firm acts as a director throughout all project phases, collaborating closely with clients, designers, engineers, and other stakeholders to develop innovative and feasible solutions.

Oosterhoff operates with a network of 15 companies and approximately 600 professionals, including designers, advisors, engineers, and makers. The group focuses on creating sustainable, healthy, safe, and inclusive living environments, spanning projects from housing and hospitals to infrastructure and monuments.

The acquisition strengthens Oosterhoff’s position in the Dutch construction advisory and engineering market by expanding its service portfolio to include integrated construction management. This enables the group to offer end-to-end project lifecycle management solutions, enhancing client value and operational efficiency.

Strategically, the deal is expected to generate synergies through cross-selling opportunities, bundling advisory and engineering services with construction management, and achieving cost efficiencies via shared administrative functions and procurement economies of scale. Operationally, the integration aims to improve collaboration within Oosterhoff’s ecosystem and streamline client engagement through unified service platforms.

Industry consolidation is accelerating as firms seek to provide comprehensive, integrated solutions. Oosterhoff’s move may prompt competitors to pursue similar acquisitions or strengthen partnerships to remain competitive. The group also faces integration challenges, including aligning corporate cultures, merging IT and project management systems, and maintaining client relationships during the transition.

Looking ahead, Oosterhoff plans to leverage the combined expertise to secure larger, complex infrastructure projects and drive innovation in sustainable living environments. The acquisition aligns with the group’s vision of creating lasting societal value through technical excellence and collaborative project delivery.
