Research Vacancies
the MaREI Research Centre in University College Cork (UCC) announced the recruitment of Masters by Research (MSc) - GEOBIM, BIM integrated Geo hazard monitoring of at risk slopes and historical retaining structures with an attractive salary of €18,000 stipend per annum.

This Research Masters Studentship is part of the wider GEOBIM project, which is a GSI funded project focussed on BIM modelling and monitoring of retaining structures in Cobh, Co. Cork. 


MaREI Centre Background

MaREI is a key research centre within UCC’s Environmental Research Institute (ERI), which is an internationally recognised Institute for environmental research dedicated to the understanding and protection of our natural environment and to developing innovative technologies, tools and services to facilitate a transformation to a zero carbon and resource efficient society. Researchers in the MaREI Centre have over 30 years of experience in conducting fundamental and applied research supported by competitively won national and international funding, and commercial contracts with government agencies and industry. MaREI’s strengths lie in the multi-disciplinary nature of its research teams, allowing it to combine insights across areas such as MRE Technologies, Materials & Structures, Observations & Operations, Coastal & Marine Systems, Bioenergy, Energy Policy & Modelling and Renewable Energy Management 

GEO BIM Background

This project will investigate the potential of combining Building information Modelling (BIM) with real time geotechnical monitoring to provide a valuable tool for assessing geo hazards, in particular soil slopes and historic retaining structures. The focus will be on creating a single virtual platform that contains historical, geometrical and geotechnical live data of identified geo-hazards in the Cobh area in Co Cork, a urban area severely impacted by geo hazards. 

The key objectives of this project are as follows:

  • Demonstrate the benefit of integrating real time sensors in a BIM platform to enhance to analysis of geo hazards in an urban setting for increased safety
  • Undertake an analysis of the impact of climate driven weather events on such geo hazards stability and assess consequences for risks mitigation.
  • Develop Relationship between direct rainfall soil saturation and wall vulnerability to produce an early warning system for at risk soil slopes and retaining walls.

Description of Research

Initially a virtual model will be developed of the Cobh area using coarse resolution data in BIM software such as Infraworks. Within the Cobh area, 2- 3 specific sites will be selected for detailed analysis and 3d modelling. Several survey methods will be trialled on these sites to identify the most suitable low cost methods of capturing high resolution geometric data. A key element of the data analysis will be documenting how weather events, such as extreme rainfall affect the behaviour of these structures. This will be achieved by installing low cost wireless sensing equipment. Ultimately the datasets created, will be analysed to create an early warning methodology.

These digital tools have the potential to be expanded to monitor the remaining geo hazards in Cobh and also applied to other retaining structures at risk throughout the country. This approach will reduce the requirement for costly and time consuming monitoring programmes as well as enhance risk analysis methods for such geo hazards.

Key Duties and Responsibilities

The Masters candidate will conduct a specified programme of research, supported by Dr. Michael O’Shea from the Environmental Research Institute’s MaREI centre for climate energy and the marine at UCC. This research includes:

  • Creation of a BIM for the study site and high resolution sub model for each Wall/slope.
  • The surveying of the walls and slopes by both UAV and Laser Scanner.
  • Selecting sensors (ground water, biaxial movement) for installation on the walls. These sensors will relay real time measurements to the cloud and these will in turn be read into the BIM.
  • Create a soil stability model (Plaxis) of the selected slopes and establish the slip circles for various combinations of climatic events. This analysis will be informed by the rainfall and ground water monitoring undertaken during the project.
  • The Integration of sensor data geotechnical modelling results into BIM.
  • Developing an early warning detections in a BIM Environment.
  • It is expected that several new semantic approaches will be developed to describe the representation of geometric and sensor data in the BIM. The integration of the data in real time will be achieved utilising object oriented programming such as Dynamo.

Selection Criteria

  • Minimum 2H1 (second class honours, grade 1) honours degree (or equivalent) in a discipline which contained a considerable element of BIM, structural analysis and/or geotechnical engineering(or anticipated minimum 2H1 class honours or equivalent if student has not completed their degree programme at time of application).
  • Proven technical competence and accomplishment in BIM – particularly Revit.
  • Interest in wireless sensors and their application to Civil Engineering
  • Demonstrable capability of working within a project team and ability to innovate.
  • Good communication, organisation and interpersonal skills.
  • Excellent academic writing skills in the language of English.

Duration: 12 months

Funding details: €18,000 stipend per annum. EU fees are covered by the grant. Non-EU candidates will need to apply for a Non-EU fee waiver.
