Highlighting Technology Advancements in 3D Modeling #AUINFRA #AU2013
After a break, the Infrastructure Symposium covered different technology advancements.
Jack Strongitharm, civil industry manager, ISM at Autodesk discussed the evolution of survey technology and data capture, where GPS has led to scanning technology and the use of unmanned aerial systems (UAS) to capture imagery and models. At the early stage there’s a need to capture for contextual information before the project starts. A quadcopter was used to create a model in Las Vegas with a recreational purpose with a detailed model captured in ten minutes and processed and modeled using Recap Photo. The project used a $10,000 custom copter, and also a $2,000 copter, comparing the results from both — proving both are useful and that the technology is quickly democratizing and getting cheaper.
Lynda Sharkey, technical marketing manager at Autodesk spoke about modeling sustainability and the ability to simulate performance with a triple bottom line benefit (people, planet, profit). Using Low Impact Development for Sites, different green elements were added to a model of a site in San Francisco to work toward sustainability goals with scoring happening as the model was embellished with rain gardens and other site amenities. The modeling was also done to include Walkscore and transit accessibility, understanding the gallons of gas saved and net carbon emissions.
Doug Eberhard, Industry Sales Development Manager at Autodesk presented a panel that highlighted 3D modeling and visualization. Panelist included:
- Kevin Gilson, manager, Design Visualization at Parsons Brinckerhoff with work on transportation projects and research and development work to expand the use of technology in the firm. Gilson highlighted a small-scale interchange project that was done in just a few days using ReCap to capture data and confirm measurements. Parsons Brinckerhoff has developed a model for the entire San Francisco Bay area, putting projects into context on a very large scale.
- Eddy Krygiel, director of Design Technology at HNTB with rail and highway work as well as large stadiums. ReCap is used for site context and documentation, with simulated flythroughs and other visualization techniques to help with 2D, 3D and 4D planning.
- Kevin Riggs, president of Cole in the United States does civil engineering, planning and sustainable land development. The company has been doing work in a distressed area of St. Louis, with a redevelopment area in the NorthSide with regeneration plans. Understanding social challenges was aided with a digital city model to understand the demographics as well as the underlying infrastructure to help solve some of the challenges. This digital city model will be used by the city’s police force for use in crowd management, and other applications.
- Keith Warren, BIM manager at VTN Consulting. The engineering firm is full service with public works, virtual design and construction as well as subsurface utility engineering. With the downturn impacting so may people in the area, the firm retooled with a look toward the future. The company created a large-scale 3D model of the city with utility information both above and underground. The model was created using LiDAR technology, so there is great detail in the model over a six-mile area. The modeling project has fed a number of projects, and led to a great improvement in safety with virtually no incidents digging into existing infrastructure since the model was implemented.
The next panel took on construction coordination with Building Information Modeling.
- Will Lineberry, design technology manager at HNTB is working on the Denver International Airport where BIM is mandated for all phases of construction down to temporary construction. Many different tools are being used including Revit and Navisworks Manage. The owner takes all the data from the models and brings it into their facility management with models as a very important deliverable for facility management. There are 260 different companies using the model, with 40 different companies creating models. The varying sophistication of model users was a challenge that needed to be normalized. Using BIM 360 Field, the project has saved better than two hours per incident, paying for the solution in a short period of time. This project forms the basis for BIM for facility management for the whole airport ongoing.
- Johann Kuppens, managing director for the City of Nijmegen, are managing a number of 3D projects in the Netherlands with modeling leading to project sequencing. One large-scale project is the re-routing of seven rivers to deal with sea level rise. To accomplish this, they have created one large-scale 3D BIM model.
In conclusion, the technology showcase illustrated the latest uses of technology in practice, with Autodesk customers showing each other their approaches and lessons learned.
