Doug Jenkins, Career Summary

Since graduating from London University in 1972 I have spent the majority of my career working on the design and construction of bridges and related structure

After working in the United Kingdom and Saudi Arabia I came to Australia in 1984, joining Maunsell at their Canberra office.

I joined the Reinforced Earth Company in 1993 as Engineering Manager at their Australian head office in Sydney.

Whilst at Reinforced Earth I was the Asia-Pacific regional representative on the company’s international technical committee and head of the international group responsible for the development of the “TechSpan” pre-cast concrete buried arch product. In this role I managed the development of product specific computer software, set up international training programmes and design and review procedures, and provided technical advice and design services to countries introducing TechSpan.

I have written and presented several technical papers on the behaviour of buried arch structures, including a paper at the recent World Congress on Earthquake Engineering in Auckland. In Australia I was directly responsible for the design of all TechSpan projects, including several large and innovative projects such as the Homebush Bay Rail Link

In July 2000 I started business as an independent consultant. Reinforced Earth remains a major client, but I am now seeking opportunities to offer my services to others.
