Mitch Liddell is geophysicist with extensive experience in electromagnetic (EM) and tomographic methods applied as part of exploration and research projects in Europe and throughout North America. He earned his PhD in geophysics from Imperial College London in 2018 and has worked throughout his career to better incorporate scientific data into industry practices. Mitch is passionate about the full cycle of geophysical mapping, from planning & logistics, to collection, to processing & interpretation, and finally communication of results and deliverables. He joined DGT Associates as lead geophysicist and GPR coordinator in 2020, overseeing all data collection and analysis.

As one of the oldest American cities, Boston holds a rich history and culture that runs not only through the streets but also beneath them. Many of the large underground infrastructure projects completed between the late 1890s and the late 1920s in Boston are still in use today. The preservation of infrastructure and the insights gleaned from the practices used to create it provide valuable lessons in how to maintain standards of excellen...

Albeit industry efforts, over 1 million underground utilities are annually hit around the world, with estimated damages exceeding $100 billion, not considering billions invested in technologies and inefficient processes aimed to protect utilities during earthworks operations. Available utility data is usually unreliable, and even if data is accurate, the excavator operator may still damage a utility.
Arising 3-D modeling, visualization, and design software (e.g., BIM, VDC) greatly enhance advanced project designs with sophisticated risk analytics and conflict resolutions that accommodate existing infrastructure and enable proactive/predictive engineering and construction. However, without standardized and accurate utility data, new advanced digital project delivery and damage prevention technologies are compromised...

GIS platforms are typically populated with XYZ coordinates with a point spacing of 1 meter or more. in fact, most traditional land surveying techniques, like GPS, often have a point spacing of 3 meters or more, and that is understandable given the procedure to obtain these points. But have you ever wondered what amount of detail is lost when increasing the point frequency? Well, in this seminar, Otto Ballintijn will demonstrate the impact point frequency has on pipe detail usin...
