We work on infrastructure and transport projects of all sizes, in both the public and private sectors. We represent our clients in all stages of their projects, from the outset through to operation or disposal.

Over recent years, PLMJ has advised on major public works in Portugal and abroad, in several business areas. We provide detailed and comprehensive advice, which always takes into account the specific nature and characteristics of each project. Our work includes designing the strategy to finance or refinance infrastructures, and renegotiating public-private partnerships. We also deal with the construction, operation, disposal or replacement of existing infrastructures. In all this work, we always respect the objectives and strategies defined by the client.

With a special focus on urban and road projects, we have supported investors, contractors, owners, shareholders and users in all aspects of these types of projects. Together with our clients, we help analyse the applicable legislative and regulatory framework. We also help analyse financing and contracting strategies, and budgetary maturity and control. Our team provides further support in governance and management of the projects, in managing risks, in optimising portfolios, and in the auditing and inspection of the works. We handle all licensing issues and the acquisition of rights of use of the property and, when necessary, any litigation and arbitration proceedings.

"PLMJ currently distinguishes itself as the most comprehensive projects team in the market, with a 360-degree view of all possible aspects of PPPs and concessions.

With the support of an agile and highly qualified team, PLMJ delivers comprehensive and robust advisory services, covering all relevant aspects for clients investing in this area.

Maria Zagallo, Pedro Siza Vieira, and Diogo Perestrelo are indispensable names in the project management sector, with accumulated experience in concessions, PPPs, and project finance unmatched by any other team in the country, encompassing the entire Portuguese experience. Each of them, with their specific background of many years in this area - whether on the promoter's, financier's, or public entity's side, across a wide variety of sectors - brings decisive value not only in terms of legal and contractual know-how but also strategic vision and problem-solving, with out-of-the-box solutions that are always balanced and promote partnership.

Joana Brandão, with her vast experience in public and private construction, complements this crucial vector and completes a unique team in the current landscape."
