[Smart Construction Korea] Ssangyong E&C’s Adoption of BIM and Drone Technologies Reduces Construction Duration and Enhances Efficiency

2020-08-21

In step with the Fourth Industrial Revolution, Ssangyong E&C has been striving to realize high-quality construction by utilizing advanced digital technologies.

A case in point is the adoption of building information modeling (BIM) in 2007, a method for 3D construction design. Thus far, BIM has been applied in more than 30 projects, as a way of preventing the overlap of construction processes and enhancing efficiency. In addition, BIM-based construction simulations have been conducive to boosting the company’s construction capabilities.

One representative building constructed using BIM technology is the State Tower Namsan, completed in 2011. During construction, for the first time in Korea, a BIM center was established on site to manage the entire construction process based on 3D models. In recognition of such efforts, the site was awarded the Grand Prize at the 2010 BIM Awards, and this experience allowed the company to achieve a gold rating in LEED certification in 2011, one of the three most prestigious certifications awarded to green buildings. Another example of BIM-based construction is the Honam High Speed Railway Line. For this project, 5D BIM technology was used for the first time in the country, to identify, in advance, the necessary quantities of construction materials and equipment. The technology was also used to simulate railway operations, prior to the completion of the project. Other projects that benefitted from reduced construction periods and costs through the use of BIM include the Royal Atlantis Resort & Residences, the representative architectural masterpiece of Dubai the Woodlands Health Campus (WHC), an advanced, future-ready hospital in Singapore the NEXEN UniverCITY, Nexen Tire’s brand-new R&D center and the Louis Vuitton Maison Seoul (LVMS), the luxury brand's flagship store in Cheongdam-dong, Seoul.

In the field of eco-friendly construction, the company also stands out from the pack. The Oceanfront @ Sentosa Cove condominium, completed in 2010, is an exclusive eco-friendly residential complex located in the high-end residential district on the waterfront of Sentosa Island in Singapore. This 264-unit apartment complex consists of five buildings ranging from 12 to 15 stories. Based solely on eco-friendly construction designs, the interior temperatures of units within the complex were lowered by three to four degrees Celsius. As such, despite the country’s subtropical climate with average temperatures of 32-34 degrees Celsius, the buildings can maintain a temperature between 29 and 39 degrees Celsius, without resorting to air conditioning. Similarly, in the W Hotel in Singapore, the utilization of low-E glass windows has reduced interior temperatures by three degrees Celsius, without the use of air conditioning.

It is also interesting to note that, using action cameras and drones, the company has been able to verify in real time the placement of heavy equipment, the observance of safety rules by workers, and other construction-related aspects of on-site working conditions. Through the ongoing utilization of the Action-Cam LTE (Long Term Evolution) Site Management System, Ssangyong E&C has been effectively managing core construction processes as well as high-difficulty and high-risk construction tasks. The system was first used at the Miryang-Ulsan Expressway construction site. Once construction workers attach an action-cam LTE device to their safety helmet, their supervisors can monitor their actions through a real-time video feed on their smartphone or PC, without time or spatial constraints. “The adoption of the Action-Cam LTE Site Management System has improved safety awareness among on-site workers. This has been very helpful in preventing accidents,” a company official said. “The adoption of advanced technologies, such as IoT, drones and BIM, has been increasing recently.”

During the construction of Ananti Cove in eastern Busan, completed in July 2019, advanced construction technology combining the use of drones and 3D modeling was utilized for more efficient management of construction processes.
