We provide our clients with comprehensive legal support at every stage – from preparing for a tender through to implementation, handover, operation and any disputes that may arise. They are supported by lawyers who take a broader view of each project: not only through the lens of legislation, but also by considering the actual regulatory, contractual and administrative risks that determine the success of an investment. We advise on projects totalling over 1,200 km of linear infrastructure – gas pipelines, transmission and distribution lines, the underground, tunnels, roads, tram lines, railways, PPP and concession projects, and ESCO schemes.
What our clients receive from us in terms of infrastructure services:
We provide support in the preparation and conduct of tender procedures – from needs analysis and the selection of the tender procedure, through market consultation and tender criteria, to matters relating to the National Appeal Chamber (KIO), non-disclosure agreements (NDAs) and the assessment of legal and regulatory risks.
We advise on the development of the legal and financial structures for projects – from SPV models, consortia and PPPs, through due diligence and project financing, to the negotiation of loan agreements, security arrangements and collaboration with investors.
We provide a comprehensive service in drafting and negotiating contracts for infrastructure projects – ranging from FIDIC contracts and works contracts, through PPP, O&M and interface agreements, to direct agreements with financiers, as well as all project security arrangements, guarantees and insurance.
We provide support during the construction phase and the handover of the project for use – from day-to-day contract management and claims, through partial and final handover inspections and final settlements, to the preparation of operating agreements and security arrangements for the warranty period.
We advise on infrastructure transactions at every stage – from comprehensive legal and regulatory due diligence, through the sale and purchase of assets and project companies, to the drafting and negotiation of contracts, and the settlement and refinancing of projects.
We help to identify and mitigate legal risks and handle disputes at every stage of a project – from contractual and tender-related matters, through proceedings before regulatory bodies (KIO, UZP, NIK), to claims, arbitration and project restructuring.
We carry out every stage with a view to safeguarding your business objectives – we combine legal precision with a practical understanding of the infrastructure market, public procurement and PPP/concession arrangements.
