Expertise and vision

Collective project management

Our investment model is based on meeting the needs of public authorities and long-term investors.

Industrial approach

We support public authorities in the delivery of infrastructure projects and services involving the development, financing and management of their assets over the long term. Our expertise covers the entire project life cycle:

  • Identification of infrastructure needs and project design,
  • Comprehensive risk analysis (financial, operational, social and environmental),
  • Formation and leadership of project consortia,
  • Coordination, planning and construction phases,
  • Operation and management of the infrastructure asset over the long term, working jointly with and on behalf of public authorities.

Responsible investment

The completion of the construction work does not signal the end of Meridiam’s involvement in the project. We are in fact actively involved in the operation and maintenance of the infrastructure, mindful of the quality of service provided to the community and the interests of all stakeholders.

This long-term commitment is instrumental to our focus on secure, safe and sustainable yields for our investors.


Projects for the community that drive growth

Meridiam focuses on investment projects that will promote long-lasting development and deliver tangible benefits to the community in terms of economic growth, urban development, employment and social cohesion.

From the outset, Meridiam adopted an Ethics Charter focusing on environmental, social and governance issues and has been a signatory of the Equator Principles as well as the United Nations’ Principles for Responsible Investment (PRI) since 2010.

Port of Miami Tunnel (PoMT)
A major urban development project to protect the environment and boost the local economy


  • Project with a total investment of US$903 million, aimed at relieving congestion in downtown Miami and mitigating the environmental impacts of traffic.
  • After three years of construction involving over 500 employees and more than 6,000 subcontractors and suppliers, the project will connect the port to the interstate highway system more quickly and safely and remove some 1.5 million trucks per year from downtown Miami.
  • Concessionaire Miami Access Tunnel (MAT), in which Meridiam holds a 93.4% stake, has launched a local workforce recruiting initiative known as “BUiLD 305” in partnership with Miami-Dade county and LiUNA Local Union 1652. The program aims to ensure that local contractors and workers will benefit from the opportunities generated by the tunnel construction project.
