Description

This class will present the automated process used to perform structural assessments for water infrastructure projects. Historically, manned inspection was the means for data collection; for example, rappelling down a dam taking photos, notes, and sketches. In remote assessment process, high-definition images are collected with small drones combined with terrestrial LIDAR (light detection and ranging) scanning. Drones offer an ideal solution because often these facilities (such as dams) are isolated but have aerial visibility. The reality capture of the structure-instead of individual images-provides a useful tool for assessment. The collected data can be transformed into 3D models utilizing AutoCAD Civil 3D software or Revit software-models which are also shareable with the remote team on the BIM 360 platform. The data can be used to monitor structure performance by taking several surveys over time. Use of a systematic approach for the survey improves the delivery quality and schedule. This tool empowers stakeholders to make informed decisions on critical structures.

Key Learnings

  • Understand the current evaluation methods and challenges
  • Gain an overall knowledge base for developing the remote assessment and monitoring procedure
  • Learn about the different methods of processing, combining, and transforming the collected data
  • Learn how to use BIM 360 to collaborate the Autodesk models with multiple discipline for real-time assessments and monitoring

Ali Afrasiabi has over 16 years of diverse structural engineering and leadership experience in new building and structure design, as well as in existing structural evaluation and rehabilitation. He is the Structural Group lead for both building and water structures for AECOM— Pacific Region. He has been spearheading several multidisciplinary projects with a focus on integrated project delivery (IPD) utilizing Autodesk, Inc., products as a platform. He led many collaboration efforts between AECOM and Autodesk to enhance the current IPD. Afrasiabi has a special interest in advancing the traditional design and calculation method to an automated approach using the vast amount of information available within 3D modeling. He is a California-licensed structural engineer and holds a Master of Science degree in earthquake engineering and a Master of Engineering degree in computer-aided engineering from The University of Southern California.
