Quantitative Based Protection Coating Assessment Using Digital Imaging and Artificial Intelligence
- Project Category: CAT 3 Industry Project
- Industry Partner: Mincka PTY Ltd
- Project Leaders: Prof. Bijan Samali, Dr Yang Yu, Dr Maria Rashidi
Project Description:
Protective coatings shield the structure from damaging aspects of the environment including sunlight, humidity, corrosive agents such as salts and windborne abrasives. Without protective coatings, the life of steel structures would be severely shortened. Therefore, it is crucial that the protective coating is always working effectively. Current assessment coatings inspection practises involve qualified inspectors. These inspectors conduct assessments of the coatings using a rating system. These practices are labour intensive and can be subjective in many cases.
Aims:
This project accordingly aims to find a reliable and cost-effective objective methodology to evaluate the corrosion condition of raw coal processing structures and coal handling and preparation plants (CHPP). It is understood that the ability to categorise by the level of damage to coatings and quantify affected areas would greatly improve the ability of plant managers to control risks and manage budgets more efficiently. Thus, the outcome of this research will address the ‘Corrosion’ priority by ensuring quantitative protection coating assessment of coal processing and preparation facilities to enable data-driven decision making.

Remotely Piloted Aircraft (RPA) survey for development of digital twin of Charleyong Bridge
- Project Category: CAT 2 Industry Project
- Industry Partner: Transport for NSW (TfNSW)
- Project Leaders: Dr Maria Rashidi
Project Description and Aims:
TfNSW is going to replace the Charleyong Bridge over the Mongarlowe River on Main Road 92. The Charleyong Bridge is identified in the Roads and Maritime Timber Truss Bridge Conservation Strategy for replacement as it does not meet current loading standards. The bridge cannot be upgraded to meet the loading standards and is expensive to maintain. Hence, it has been decided to develop the digital twin f the bridge before demolition. Research has been carried out to explore the best integration approach for aerial and terrestrial data capture.
Digitisation of eleven timber truss bridge in New South Wales (NSW)
- Project Category: CAT 2 Industry Project
- Industry Partner: Transport for NSW (TfNSW)
- Project Leaders: Dr Maria Rashidi, Prof. Bijan Samali
Project Description and Aims:
The NSW Government manages most of the state’s remaining timber truss road bridges. These bridges have high individual and collective heritage value. Relying on our unique capabilities in terms of utilising emerging technologies such as drones and laser scanners for asset management of civil infrastructure assets, we have been in charge of the digitisation of numerous heritage bridges in NSW. In this project, the scope of work is going to be a digital twin and BIM development of eleven timber truss bridges in accordance with the Timber Truss Bridge Conservation Strategy and Heritage NSW requirements. Due to the challenging nature of the work, some researchers are going to be involved in the project.
The list of bridges are as follows:
- Clarence Town in Hunter Region.
- Junction Bridge, Rouchel Brook in Hunter Region.
- Gillies Bridge, Black Creek in Hunter Region.
- Tooleybuc in South West Region.
- Cobram Bridge in South West Region.
- Paytens Bridge in Western Region.
- Warroo Bridge in Western Region.
- Rawsonville Bridge in Western Region.
- Tenterfield Creek in Northern Region – Rail Bridge.

Automation of compliance checking at early stage of design submission using Artificial Intelligence (AI)
- Project Category: CAT 3 Industry Project
- Industry Partner: Commnia Construction Software Australia
- Project Leaders: Prof. Srinath Perera, Dr Maria Rashidi, Dr Ehsan Sorooshnia
Project Description and Aims:
Automated compliance check of the preliminary drafts against the council guidelines as well Building Code of Australia is the principal aim of this project. Early submitted design drafts can be automatically checked using AI tools and the possible discrepancies can be identified. In addition, the clients can do a quick compliance check and give the report. This helpful practice could be added to BIM in a way of real-time checking the design criteria. The required 3D model can be built using image processing tools. Not only the new developments can utilize this app but also old documents which are clear enough in the context of figures or some old developments with no digital documents could benefit from this new app. Python Image Processing which is one of the core areas of Artificial Intelligence and Computer Vision could be utilized to extract meaningful data from preliminary design documents in order to design this app. The main benefits of this innovation for the industry are as follows:
- Saving time and cost of compliance checking;
- Increasing process speed and accuracy;
- High potential to be added to BIM platforms;
- Ease of operation and being user friendly.

Work Health and Safety of Non-Destructive Digging and Asbestos Contaminated Soils
- Industry Partner: Centre for WHS, EDP Consultants, Macquarie University, Deakin University
- Project Category: CAT 2 Industry Project
- Project Leaders: A/Prof. Payam Zekavat, Dr Maria Rashidi
Project Description and Aims:
NDD uses high-pressure water jet to soften soil before being vacuumed. Applying water jet on asbestos contaminated soils is prohibited by the regulation. A preliminary study has shown that the water jet impact does not increase release airborne asbestos fibres. My industry partner, EDP, agrees with this finding. The project is accordingly set to run a series of experiments to collect evidence to enable the regulator issue an industry-wide exemption for NDD industry to excavate on asbestos impacted soils. A safe work procedure guide will be produced as the outcome of the project.
