Mr. Leo Kwan is the founder and Chief Executive Officer of LiDARist Co. LTD., which is a start-up with core developments on point cloud post-processing in deep-learning-based approach. He has worked in the construction industry for more than 15 years as project manager and implemented BIM into his supervised projects and teams. He and his team are currently working on a deep-learning-based semantic segmentation of underground utilities point clouds.

The talk summarizes a market product of deep learning based semantic segmentation of point clouds and automatic 3D reconstruction of as-built BIM for underground utilities and pipework for 3D GIS. The presentation covers a general workflow of the approach (including point cloud labeling, definition of classes, deep neural network, information extraction, and pipe modeling), accuracy of semantic segmentation, real case studies, and foreseeable challenges down the road. Also, the speakers wi...

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...
As the world continues to grow and urbanize, new urban infrastructure is being constructed at an unprecedented rate while old world infrastructure is being replaced and upgraded. This has lead to a greater demand for accurate and current utility locating and mapping. This demand is further exacerbated by the fact that infrastructure construction costs continue to rise and the slightest delay or extra cost associated with insufficient utility locating has an...
