Conference schedule

Thank you to our Platinum Partner, New Brunswick Department of Transportation and Infrastructure. Schedule details will be updated regularly by the conference committee and are subject to change.

9:30 a.m. – 12:30 p.m. | Technical Tour - Mactaquac Generation Station provided by A.D. Fiander Associates, Aitken/ Mactaquac Dam

  • The Mactaquac area, 20 km north of Fredericton, is uniquely defined by its hydroelectric dam on the Saint John River. The Mactaquac Generating Station offers a fascinating tour, sharing the history of the massive dam built between 1963 and 1968, and an overview of how the largest hydroelectric generating station in the Maritimes operates.

9 a.m. – 3:30 p.m. | Workshops – Rooms 208 and 204, Wu Centre

  • Workshop #1: Introduction to Reality Capture Technology for the Built Environment and HBIM. Reality capture techniques and tools, such as LiDAR, photogrammetry, 360-degree photography, virtual reality (VR) and unmanned aerial system (UAS), have been adopted by the architecture, engineering and construction (AEC) industry with various applications on both new-build and heritage projects. These applications of reality capture include as-built documentation, construction progress monitoring, project team coordination, quality assurance (QA) and quality control (QC), progress reporting, preservation planning, damage assessment, restoration, rehabilitation, and marketing, etc. The data collected through reality capture processes at historic structures can be further processed and used to develop Heritage Building Information Modeling (HBIM) models, presenting an advanced method for digital preservation and interpretation.

  • Workshop #2: Reality Capture and Augmented Reality for Emergency Response. This workshop will showcase the use of Augmented Reality and Reality Capture technologies for emergency inspection, search and rescue. Inspection in confined areas after a disaster, or search and rescue for emergency responses, usually pose significant risks to the on-site personnel. Especially when the on-site activities are affected by occlusions, uncertain hazards can threaten the safety of professionals. Reality capture technologies have the potential to improve emergency responses and forensics engineering. This workshop will demonstrate the latest technologies developed by the Informatics, Cobots and Intelligent Construction (ICIC) lab at University of Florida. A robot dog carries LiDAR and depth camera sensors to enter into an unknown space. The spatial data and mesh data are captured and optimized by in a ROS system. Then a cloud server is used to transfer the real-time point cloud data to Unity, a game engine. VFX and shaders are applied to the raw point cloud data to optimize the rendering. Finally, the rendered point cloud data is sent to a HoloLens 2 headset. A search tree-based method is applied to register the point cloud model with the HoloLens 2 viewpoints, to generate an illusion of “seeing through walls”. Participants will have an opportunity to experiment with the technologies themselves.

1 – 2 p.m. | OCRC Five-Minute Student Competition – Aitken, Wu Centre

5 – 7 p.m. | Technical Tour provided by A.D. Fiander Associates, UNB Kinesiology Building

  • Dr. Amin Hammad | Abstract: Towards Near Real-time Digital Twins of Construction Sites. 4D simulation can be used in the planning phase of a project for constructability analysis, which aims to optimize construction processes and improve safety management. The same 4D simulation can be used as a digital twin in the construction phase for progress monitoring and identifying potential safety issues based on micro-schedules. A micro-schedule is a schedule listing tasks of short durations (i.e., minutes to hours) with the information of the resources assigned to each task (i.e., workers, equipment and materials). The site data can be collected using computer vision or real-time location systems (RTLS) to identify and recognize the activities of construction resources, as well as to capture the progress of the project. This talk aims to explore the possibility of developing near real-time digital twins of construction sites. The digital twin is developed as a high level of development (LOD) 4D simulation based on the captured computer vision and RTLS data. A case study based on a recent project will be used to demonstrate the proposed approach.

8:30 – 10 a.m. | Keynote speaker & plenary session 3 – auditorium, Wu Centre – with Ionnis Brilakis

  • Prof. Ioannis Brilakis | Abstract: Digital twinning methods can produce a reliable digital record of the built environment and enable owners to reliably protect, monitor and maintain the condition of their asset. The built environment is comprised of large assets that need significant resource investments to design, construct, maintain and operate them. Improving productivity, i.e., efficiency and effectiveness, and creating new, disruptive ways to address existing problems throughout their lifecycle can generate significant performance improvements in cost, time, quality, safety, sustainability, and resilience metrics for all involved parties. Creating and maintaining an up-to-date electronic record of built environment assets in the form of rich Digital Twins can help generate such improvements. This talk introduces research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting digital twin, automatically extracting defect spatial measurements, and sensor and sensor data modelling. The results of these methods are further exploited through their application in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage.
