Client SatisfactionThe construction practice at JLSW Janaszczyk Lis & Wspólnicy stands out as a key destination for contractors, engineering companies and architects seeking guidance on a range of investment projects, including residential, commercial, infrastructure, green energy and sustainable construction. Public procurement issues and contentious mandates are both strengths of the team, which often represents its clients in FIDIC-based contract disputes, as well as those relating to the extension of time, construction defects, and contractual penalties. Poznań-based Marcin Lis co-leads the group with Tomasz Janaszczyk in Warsaw. Olga Stiefel-Brzezinska is also an active team member.
