Smaller companies private equity firm Anacacia Capital is backing the merger of investee company RP Infrastructure with another project management company, Ranbury.

The merger will create a business with more than 300 employees working out of five offices along the Australian east coast.

Anacacia will continue as the major shareholder in the combined business.

Ranbury, which employs more than 140 people, works mainly on Queensland development projects within the transport, property, buildings, resources and utilities sectors. RP Infrastructure focuses on similar operations in NSW and Victoria.

RP Infrastructure chief executive David Gundy will lead the expanded business while Ranbury managing director Brett Magnussen will take on the role of national director of project delivery services. Sam Cook of RP Infrastructure will be head of advisory services.

Gundy said the merger will expand the company’s footprint enabling it to capitalise on Australia’s large pipeline of infrastructure projects, particularly in Queensland.

“With the 2032 Brisbane Olympics and the state’s investment in areas such as transport, water, energy, sport and health infrastructure, Queensland will be leading the way with many exciting project opportunities over the next decade,” he said.

Magnussen said: “The merger provides a solid platform for future growth through an expanded service offering and deeper capabilities for clients.

“The merger will create a host of exciting opportunities for all of our teams, with the opportunity to become a national consultancy with extensive depth and capability across the eastern seaboard.”

Anacacia Capital invested in what was then Root Partnerships in 2019. The company changed its name to RP Infrastructure in 2022 following the acquisition of InfraSol Group which increased its transport and utilities capabilities.

RP Infrastructure has a team of 165 people based in Sydney, Melbourne, Brisbane and Canberra.
