Road map for pipeline strike avoidance

Tuesday January 31st, 2017

We published this Road map after our review study of the existing technologies for detection of steel high pressure pipelines. Based on the review, we propose various steps to further improve the technologies and data related to local push/pull detection, and global monitoring systems. The full report can be downloaded from our project-page. 

Assessing the Underworld comes to Twente for data collection

Monday 26 Sept - Friday 7 October

Doctoral researcher Aryan Hojjati from the University of Birmingham visited Twente for an exchange meeting on utilities construction. Aryan presented his PhD research project and the larger program that it is a part of. Aryan will conduct case studies in the Netherlands to identify and quantify factors that influence the life cycle costs of inner city utility construction solutions. He develops a framework that compares, for example, the installation of utilities using trenchless technologies, open-cut solutions, and multi-utility ducts. Some Dutch projects will be investigated to validate the model and empirically derive quantitative parameter data. A part of Aryan's presentation is visible below.

Excavator training collaboration with SOMA

21 September 2016, SOMA college Harderwijk  

CM&E staff members André Dorée, Farid Vahdatikhaki, and Léon olde Scholtenhuis visited SOMA college in Harderwijk. SOMA college is the Dutch education and training institute for construction crew, heavy equipment operators, equipment engineers, and jobsite foremen. SOMA educates about 1000 students annually (both practitioners and freshmen). During the visit, the researchers explored the simulator training room, and construction training site. In addition, they sat together with the chair of the board, educational director, and various course instructors to discuss plans to bring closer Twente’s ZoARG | ReDUCE research ( activities with SOMA’s education on utility strike avoidance and excavator safety. The groups meets again soon for a workshop where research, development and educational projects for future will be defined.

Excavation damage, health and safety meeting RMIT, Velin, UTwente

Thursday 14 July 2016, University of Twente

Dr. Jan Hayes visited the University of Twente for several research meetings with her consortium partners at the EPCRC (Energy Pipeline Research Council). She passed by the University of Twente to tell about the EPCRC. Furthermore she elaborated on her research projects about, for example, the influences of the supply chain, rules and organizational structures on excavation damages. Particularly the social science viewpoint and relation to theories such as High Reliability Organizing were of great interest also for the Dutch research group. In addition to this presentation, Mark Engbersen presented on behalf of the Dutch Association of Pipe Owners (VELIN) and their ambition to significantly reduce excavation damages to the pipelines that tansport hazardous materials. 

The presentations of the two are provided below.

CROW Infradagen 2016

Wednesday and Thursday 22 & 23 June 2016, Papendal, Arnhem

The Dutch Infrastructure Days (CROW Infradagen) had two sessions dedicated to subsurface construction. Also the key note lecture (in Dutch) of the bi-annual conference outlined how buried utilities and lack of subsurface planning challenge city engineering projects in nearby future. In addition. One presenteation was given by Fatemeh Mahmoudi. This ZoARG P.D.Eng. student presented findings from her initial analysis. This presenation is provided below. Her paper can be downloaded from the CROW website More presentations can be retrieved from the Dutch ZoARG | ReDUCE page.

GeoBIM dec 2015

10 December 2015

André Dorée gave a presentation at the National GeoBIM Conference. He gave his view on how city 3D models could enhance utility construction, and how this subsequently contributes fundamentally and significantly to the many initiatives that aim to make cities smarter.
