BSc, MSc, DIC, CMEngNZ, CPEng, IntPE(NZ)
Andreas has worked for over 19 years on numerous large scale civil infrastructure, commercial and residential projects in New Zealand and Greece.
His consultancy work includes advising on realistic, practical solutions to often problematic ground conditions and the interactions of soils, foundations and structures. He has successfully led and managed teams for notable projects such as the Kawarau Falls Bridge (NZTA), the Egnatia Odos and Patra-Athens-Thessalonika Highway (EYDE-PATHE) in Greece, and numerous individual projects for the Canterbury and Kaikoura earthquake recovery programmes.
Andreas has published several papers on liquefaction susceptibility and ground reinforcement for soils susceptible to liquefaction. He actively participates at a technical and delivery level and in recent years is increasingly involved in forensic and legal work to provide timely, smart designs, applying innovation, intelligent risk and ingenuity on every possible aspect for our clients.
