3D planning for the Honam High Speed Railway steps into the future with ‘5D BIM’
Process and cost derived thru 3D mgmt and application of timelines, thus minimizing errors
Safety, equipment, test operations with an ‘avatar’: blending IT and construction for optimum results

3D design technology that is normally reserved for high tech building designs has recently been applied to a rapid railway project.

Ssangyong E&C (President Kim Byeong-ho), which lately has been in the process of designing and constructing (turnkey) the 4-2 section of the Honam High Speed Railway, has announced the introduction of Building Information Modeling (BIM).

BIM(Building Information Modeling) refers to the process of making a regular 2D CAD plan into 3D, thus determining potential errors and issues that can occur when just using 2D plans.
Ssangyong even went further to add more dimensions to the 3D plan, like procedures and the introduction of materials, construction costs per period, to upgrade the plan into a 5D BIM plan.

Hence, the 9.38 km site can be simulated for construction and reserve of materials, the flow of construction equipment used on site, as well as virtual traffic on the finished high speed railway ? which can be checked before construction even starts.

This technology is web-based, so that there is no need to install separate software on the compute. This allows for simulations to be run anywhere and the avatars can be used for safety training to prevent accidents.

Executive Director Cho Hyun, from the Ssangyong E&C Civil Engineering Division, explained, “This is such a useful tool in predicting what cannot be foreseen, like checking the most suitable underground construction methods for the specific terrain conditions,” and added, “using this technology, we could expect about 5% reduction in construction time and 5 to 7% reduction in the amount of rebar used.”
