Company History
Where it all began
s2 corporation was formed in 2004 with a vision from Murray Ellen to service companies with solutions using his unique and patented technology developed over the years. His vision of s2 was greatly influenced by the great achievements of his father Peter Ellen.

Graduating from the University of New Zealand in 1952, Peter Ellen dedicated his life to the behaviour of structures and the materials from which they are built. Peter’s 40 plus year career was filled with many great achievements having designed more than 250 innovative cost-saving structures in 14 countries.
In 1973, Peter moved to Hong Kong and established the design firm Peter Ellen & Associates Ltd. It was here he specialised in steel and concrete structures, particularly in the designing, full-scale testing, and construction of developments in Australia, the Philippines, Hong Kong, China and Japan.
Peter was an expert on the modes of failure in both high-rise and low rise buildings with reference to earth quakes. He was the author of over 80 technical papers and 15 unpublished reports of building failures and failure tests. Peter specialised in fracture mechanics of materials particularly concrete and developed new types of steel strand, reinforcing bars, and high strength concrete (over 200MPa). He was the holder of many patented structural systems.
Peter received many international awards and titles for his skills and accomplishments with post-tensioned steel and concrete composite structures.
Helsal
One of Peter’s great triumphs was performing the structural design for Helsal, which won the 1973 Sydney to Hobart Yacht race. Helsal was special not only for her win but also because she was constructed out of concrete.
