Danish engineering firm Ramboll to acquire OBG

December 17, 2018


Copenhagen-based Ramboll Group A/S ("Ramboll") has entered into an agreement to acquire the US engineering and design consultancy O'Brien & Gere ("OBG"), adding 900 experts within water, energy, environment and advanced manufacturing with effect of 1 January 2019. With the acquisition, Ramboll now has 2,000 experts in the US and 15,000 globally.


Andrej Avelini and Josh Lahre supported Ramboll from the initial screening of candidates, through the first contact and the negotiations. Without their support we would not have been able to achieve this great result,” said Jens-Peter Saul, Group CEO of Ramboll.


Andrej Avelini and Josh Lahre, during their association prior to forming AEC Advisors, initiated and advised Ramboll on this transaction with OBG. Andrej and Josh have recently founded their own firm, AEC Advisors (www.aecadvisors.com), along with Tyler Albright and Joe Smetona, to provide M&A advisory, valuation, KPI benchmarking, and ownership transition services to the AEC industry.   

Comments from Ramboll's press release:  


Jens-Peter Saul, Group CEO of Ramboll: “Growing in North America has been a strategic priority for us since we established our US presence in 2014 with the successful acquisition of ENVIRON. Together with OBG we can build on the platform we have developed in the US. By combining our analytical and consulting-oriented business in the US with the strong project execution capabilities of OBG, we will be able to deliver full-scale, integrated solutions to our clients - from front-end consulting work to back-end execution. Like Ramboll, OBG is a highly purpose-driven company with strong fundamentals. The strong commercial and cultural fit makes me confident that we will be able to leverage the many synergies between our companies to the benefit of our clients and colleagues."


Jim Fox, CEO of OBG: "We see joining forces with Ramboll as a tremendous opportunity to widen our client base in the US as well as extend our client relationships globally. Additionally, this brings together world-class thought leadership and the capacity to solve the challenges caused by global megatrends such as urbanisation, climate change and resource scarcity. I have full confidence that this combination will result in more growth opportunities for our talented people and innovative solutions for our clients.”
