Walter Vasquez
Business affairs counsel | Hitachi Rail STS
What are the key projects that you have been involved in over the past twelve months?
Over the past year, my work as Business Affairs Counsel for Latin America at Hitachi Rail STS has continued to focus on the legal and contractual management of high‑impact infrastructure projects across the region (in Peru and Panama).
A core component of my role has been overseeing complex legal matters related to Hitachi Rail’s participation in the Lima Metro Line 2 Project, a landmark transportation initiative in Peru with a combined investment of approximately $1.2bn for the company. This work involves guiding strategies on contractual administration, regulatory interfaces, corporate governance and dispute‑avoidance frameworks involving the State, consortium partners and multiple nominated subcontractors.
I have also supported the Panama Metro Line 3 Project, providing 360° contractual governance assistance across client interfaces, consortium partners and subcontractors. This has involved advising on risk allocation, contract administration and strategic alignment to ensure smooth project execution.
In addition to my in‑house responsibilities, I have remained active as a legal expert and arbitrator, issuing expert opinions in national and international arbitrations on construction law, real estate, concessions and complex contractual disputes. Publicly available academic sources also reflect my continued contributions to legal scholarship, particularly on construction contracts, remedies and private law.
Are there any particular challenges for which in-house counsel should be preparing in 2026?
In-house counsel should anticipate a 2026 environment shaped by heightened regulatory scrutiny, increasing contractual sophistication, and macroeconomic uncertainty. Major infrastructure and transportation projects are progressively adopting advanced contractual models (including collaborative contracting schemes), which require deeper technical understanding and more proactive legal participation.
Counsel must be prepared to design agile risk allocation mechanisms, manage multi-stakeholder contractual governance, and ensure operational continuity amid regional political volatility. Strengthening dispute‑avoidance practices and embedding legal reasoning early into commercial and engineering interfaces will be essential.
Have you had any experiences during your career as a lawyer that stand out as particularly unique or interesting?
Several experiences have been particularly meaningful. Working on the Lima Metro Line 2 Project has offered a unique opportunity to operate at the intersection of public infrastructure, international contracting and complex dispute‑avoidance strategies.
My roles as arbitrator (AmCham Peru CARC-PUCP and other institutions) and legal expert have also been especially enriching. I have had the opportunity to issue expert opinions on intricate contractual scenarios, including construction variations, contractual performance, real estate structures and concession frameworks, matters widely reflected in publicly available academic records.
Finally, my academic career — teaching at PUCP, Universidad del Pacífico, Universidad Nacional Mayor de San Marcos and the Universidad Externado de Colombia — has provided a complementary perspective, reinforcing analytical discipline while keeping me engaged with the latest developments in private law and contract theory.
