When it comes to the superstructure of a mid-rise building, there are many slab options. Traditional systems such as cast-in-place concrete or steel deck are available, but new systems are also increasingly popular such as mass timber, deep steel deck and hollow core slabs. On one of our ongoing projects christened Glendale Crossing II in London Ont., hollow core slabs are used to achieve unique, outstanding results:
- 12 meter (39 feet) clear spans
- Slab depth of 300mm (12 inches)
- Dead weight of only 4.12 kPa (86 psf) + topping
- Approximately 6 000 square feet installed in one single day,
Designed by Gray and Fick Ltd. And Cornerstone Architecture Inc., Glendale Crossing II is the 4th project with Schlegel Villages where hollow core slabs are used in conjunction with Deltabeam. Once again, this building was designed with the end user in mind. On top of the characteristics listed above, the structure also allows for:
- Sound rating values superior to 60 STC and IIC
- Fire rated: integrated 2-hour fire rating, even for exposed steel Deltabeam
- Slim floor: most of the Deltabeam + slab depth is inferior to 300mm (12 inches)
- Immediate access to built space: hollow core slabs need no shoring
The project in construction is located at 3030 Singleton avenue in London Ont.
