During his time in consulting practice Professor Partridge has also undertaken investigations for more than 100 residential townships, including suitability assessments for on-site sanitation, and has completed materials and subgrade surveys for more than 500 km of rural roads. He is familiar with labour-intensive construction methods, having published internationally on this subject.
