The latest move by Drees & Sommer follows its acquisition of Northern Ireland consultant Johnston Houston last September.

The RSP deal will add 60 new employees to the Drees & Sommer team, increasing the total workforce to over 300 employees across 12 offices in the UK.

RSP will continue to operate as “RSP Consulting Engineers – Part of Drees & Sommer” under the leadership of the current management team, before officially rebranding to Drees & Sommer at some point in the future.

Kenneth Wood, Managing Director of the UK and Partner at Drees & Sommer, said: “The acquisition of RSP is a transformative step for Drees & Sommer in the UK. This merger not only strengthens our market position but also significantly enhances our service offerings.

“RSP’s unparalleled expertise in design engineering and strength in complementary sectors such as Data Centres and Life Sciences, combined with our extensive experience in sustainability and real estate, creates a unique synergy that will drive innovation and excellence.

“We are excited to welcome RSP to the Drees & Sommer family and look forward to achieving new heights together. This partnership is a testament to our commitment to delivering exceptional value and sustainable solutions to our clients.”

Graeme Fraser, Partner at RSP, added: “This merger is a monumental opportunity for RSP and our team. By joining the Drees & Sommer UK team, we are poised to leverage their extensive resources and global expertise to elevate our service offerings.

“Our employees, who are the backbone of our success, will have access to unparalleled career development opportunities and the chance to work on groundbreaking projects. We are excited about the future and the transformative potential this partnership brings, ensuring we continue to deliver exceptional value to our clients.”
