SSI was founded in Johannesburg , South Africa in 1922. Registered as Stewart Scott (Pty) Ltd and trading as Stewart Scott International, the company owes its name to its far-sighted founding fathers – George Stewart, a specialist in water cycle and municipal services projects and Frederick Scott, whose forté was transport and structural design.
An innovator from its early years, SSI was one of the very first independent consulting engineering companies in Southern Africa and later, also one of the first to be established as an empowerment company.
Today SSI is a member of a close-knit global alliance, a leading consultancy and engineering firm operating in the public-private spectrum. We offer multi-disciplinary services for the sustainable development of our living environment, based on mutually beneficial relationships with our clients, employees, partners, shareholders and society as a whole.
