​

This is a $90 million 6-storey purpose-built ramp-up warehouse facilities with the 1st storey designed for storing flammable material and 2nd storey for hazardous goods, while the 3rd to 5th storey are designed for general warehouse storage. 

​

Each warehouse has its dedicated loading and unloading bay served by a single loop ramp over 10.2m floor to floor height, with typical column grids of 11.4m.

​

The structural concept for the building is deploying post-tensioned flat slabs with RC columns and walls as its vertical elements to optimise the design. This building is also designed for seismic effects; shear walls had been adopted to resist the lateral actions. Each floor has a typical imposed load of 20kPa. A hybrid foundation system of precast RC driven piles and RC bored piles were adopted based on the soil profiles and to balance safety and cost considerations.

​

One technical challenge for this project is that there are traces of limestones underlying the site. Additional tests, considerations and ground improvements had been adopted to ensure that a safe and robust foundation system can be implemented.
