Katja Perätalo

Partner

Katja Perätalo advises clients in industrial construction projects in all phases of negotiation and execution, and both in terms of non-contentious and contentious aspects. Katja has particular expertise in EPC & EPCM projects (based on FIDIC terms and otherwise), projects based on disaggregated contracting/procurement strategies, and Contracts & Claims Management leadership both on a global organisational level and within a particular project or contract. She works on projects across industries ranging from renewable energy, green hydrogen, nuclear and bioproducts to production plants and facilities within e.g. oil&gas, defence, food and pharma. She is also active in Hannes Snellman’s ESG Group.

Katja holds a Doctor of Laws / LL.D. degree from the University of Helsinki and a M.Sc. (tech) degree from Aalto University. Her doctoral dissertation covers the interface between tort and contract law in the context of liabilities between parties of a large-scale construction project. She is a recurring speaker on topics especially within construction and contract law.

Before joining Hannes Snellman, Katja was in charge of contracts & claims management and a member of the management team of the procurement organisation at one of the largest industrial companies in Finland. She also has several years of experience from working in another leading Finnish law firm, including a secondment to a leading international law firm in London. Katja originally started her career as an analyst in the real estate sector.

Katja is a former international-level athlete, a European Championship finalist, and World Championship semi-finalist. She held Finnish national records in swimming from 2004 to 2015.

Exceptionally good in her line of expertise. Thorough understanding of both legal aspects as well as the real-life challenges that the client is facing. Always available, easy to work with.
