Dr Ahmed WA Hammad is a Senior Lecturer at UNSW Built Environment, UNSW Sydney. His research focuses on the use of operational research (OR) techniques, including machine learning and mathematical optimisation, linked with digital engineering platforms such as Building Information Modelling (BIM) and City Information Modelling (CIM), for enhancing decision-making and sustainability in the built environment. His past works included the introduction of a systematic framework that relies on neural networks and BIM for building performance enhancement, along with proposing a mathematical optimisation platform for organising construction sites to improve productivity and enhance safety by minimising high noise level exposure. Dr Hammad has an extensive industry background in BIM implementation, virtual reality, prefabrication, optimised design and scheduling techniques.
