Research

Current research: Reduction of Damages to Utilities and Careful Excavation

One of the main issues during society’s transition toward smarter cities relates to the maintenance and upkeep of public infrastructure. It becomes more complicated, for example, to add new networks (e.g. fiber optics, smart grids, submerged waste transport etc.) and maintain existing buried utilities. Besides the physical limitations, information uncertainty (inaccurate or incomplete maps) and coordination issues caused by privatization make add more complexity to execution of inner city streetworks. The ZoARG | ReDUCE research programme that I lead aims to study and improve the existing situation by. Key research activities are centered on information, coordination and supporting technologies. Currently, we have a growing research and industry consortium that collaboratively:

  • Identifies how subsurface information can be effectively modelled to support life cycle decisions;
  • Further develops and implements subsurface mapping technologies, practices, and codes;
  • Implements detection and information solutions in practice to iteratively improve the tools, engage practice in advancing the field of smart inner city engineering, and develop new education curricula for inner city engineering.

Most recent projects in this domain are:

  • 3TU.Lighthouse project Spying the Underground www.spyunderground.nl
    This project aims to develop data models that stores fuzzy location information of visualizing underground utilities. Collaboration with Dr. Sisi Zlatanova TU Delft and her students
  • NOW STW TISCALI project
    Project to be started by 2017. Focus is on developing a three stage approach for systematic areal sewage inspection that uses thermal imaging, ground penetrating radar and in-pipe inspection. In collaboration with Ir. W. Timmermans, Prof. M. van der Meijde & Dr. E. Dertien.

PhD research: Enhancing Reliability in Subsurface Utility Construction Projects

Supervisors: Dr. Timo Hartmann, Prof. Dr. Ir. Ing. A.G. Dorée

Subsurface utility reconstruction projects have a great impact on their surroundings. Especially in densely occupied urban space, utility reconstruction works appears difficult to plan and coordinate. Despite good intentions and significant coordination efforts, the projects are often on hold, causing re-planning and over-runs. I used the lens of High Reliability Organizing to study reliable coordination in these projects. In 2012, I conducted ethnographic studies to describe coordination practices in five sewer projects. In 2013-2014 I evaluated how 4D visualization tools supported this practice, by meaningfully formalizing and integrating multi-actor project schedules. Additionally, municipal project coordination decisions, 4D-CAD implementation, causes of excavation damage, and simulation of sewer line works were investigated in supervised student projects. I defended my thesis work on Oct-22 2015. Findings showed that virtual design and construction tools such as 4D CAD help to mindfully enhance coordination in multi-stakeholder utility projects.
