WSP’s UK heritage dates back to the late 1800s through firms like MRM Partnership, Kennedy & Donkin, and Merz & McLellan — later integrated into Parsons Brinckerhoff. Founded in 1969, William Sale Partnership (WSP) was acquired by Genivar and grew rapidly across the UK, South Africa, and the Nordics. Since the 2000s, WSP has expanded its global footprint with strategic acquisitions in Sweden, Finland, the Middle East, and France.
The addition of Golder in 2021 enhanced our geotechnical and environmental expertise across Europe. In 2022, we welcomed 1,700 experts through acquisitions including BOD in Spain and Wood’s Environment & Infrastructure business across many countries. BG Consulting Engineers joined in 2023, strengthening our teams in Switzerland and France. In 2024, Proxion and 1A Ingenieros reinforced our capabilities in Nordic rail and Spanish energy. Most recently, the 2025 acquisition of Lexica expanded our advisory services and solidified our leadership in healthcare and life sciences.
