Acknowledgements

I am grateful to my principal supervisor, Associate Professor Pejman Sharafi, and my co-supervisor, Dr Jun Wang, whose guidance, patience, and critical reading shaped this work at every stage. Their willingness to let the argument develop on its own terms, while holding it to account, made the thesis possible.

I thank the Centre for Infrastructure Engineering and the School of Engineering, Design and Built Environment at Western Sydney University for the resources, candidature support, and research environment that sustained this project.

Any errors that remain are my own.
