Hanwha Construction Develops Logistics Center Specialized 'WBS Method'... Strengthening Order Competitiveness

WBS (Wide Beam System) Method 'Hollow Core Slab (HCS) + Wide Lightweight PC Beam' Configuration Diagram

Hanwha Construction announced on the 25th that it has developed and completed a trial construction of the 'WBS (Wide Beam System) method,' a construction technology specialized for logistics centers.

The WBS method consists of wide lightweight PC beams and hollow core slabs, and by utilizing the PC hollow cross-section, it is an economical method that reduces weight and concrete volume. The WBS method has excellent stress resistance, allowing construction without columns and also offers superior seismic performance.

Hanwha Construction's WBS method is expected to differentiate itself from existing logistics center designs through cost reduction and improved constructability. Logistics centers generally apply the PC method to secure cargo loading and unloading space and high floor heights, but the conventional PC method has low constructability due to the heavy weight of the members themselves. Therefore, reducing the weight of members is the top priority in PC methods for logistics centers.

Since September 2020, Hanwha Construction has been jointly conducting research and development on the 'Logistics Warehouse PC Method Specialized Item' for about a year with Samil C&S and OneTop Structural Engineering, and after revisions and improvements, completed the current WBS method.

Patent application was filed in February this year and patent registration was completed at the end of July. In April, structural performance testing was completed through the Korean Concrete Institute, certifying excellent seismic performance. Subsequently, a pilot construction was carried out on the 18th at the Samil C&S Buyeo factory site.

Yoon Yong-sang, Head of Hanwha Construction's Architecture Business Division, said, "With the development of the 'WBS method,' Hanwha Construction will not only reduce costs but also further strengthen its technological competitiveness in the PC field and continuously expand orders for various projects applying the PC method, such as logistics centers and knowledge industry centers."
