Since graduation David worked in the engineering consulting business in the UK and Australia specializing in Computer-Aided Engineering to analyse civil, structural, geotechnical and mechanical systems subject to complex perturbation. In the mid-1990s, the notable project performed by him was the 3D finite element analysis (FEA) for the raising of Warragamba Dam involving the simulation of staged construction, flood loading and earthquake response. Between 1992 and 1997 he was a part-time lecturer at the School of Civil & Structural Engineering, University of Technology, Sydney.
While working for WorleyParsons’ Advanced Analysis Group, David pioneered the use of computational fluid dynamics (CFD) modelling of dam spillways in Australia evaluating their hydraulic performance for different flow and flood conditions. Since then other hydraulic structures such as pumping stations, fishways, etc. have been analysed. He was invited to present his CFD modelling experience at a HKIE technical seminar in 2015, and more recently he took part in the 2-day brainstorming seminar on designing long water diversion tunnel for a major water project in Thailand.
Another area of expertise is soil-pipe interaction modelling in particular buried pipeline subject to natural geohazards such as slope instability, sinkholes, etc., and man-made hazards such as mine subsidence, motorway and railway embankment construction. The outcome of the project involving safeguarding critical high pressure gas pipelines subject to mining subsidence has led to the inclusion of strain-base design in the Australian Standard, AS2885.1, for gas pipeline design. A number of technique papers on this topic were published by David and co-workers.
David has been invited to review technical papers for Journal of Hydraulic Research and Computers and Geotechnics Journal.
