As explored in our previous post, UBC Conceptual Massing, we have been investigating the development of 3 different timber based construction systems to meet the volumetric requirements for the UBC Brock Commons project. This simplistic model is based off of V1 in the early massing stage. The model is focused on linear loads and repetitive construction techniques. This system generates a monolithic block specifically designed for ease of construction. 11 stories of CLT hybrid construction are used to produce a robust structural system containing 400 mixed form student housing units.
Elevator and staircase core CLT panels run vertically as opposed to horizontally. The rest of the structure is erected sequentially floor by floor.
Each floor consists of:
A CLT system of this nature would need some adjustments to achieve heights of 16-18 stories. The concrete composite floor system aids in regards inter-story shrinkage and fire suppression tactics.
This type of a design has numerous benefits from a construction point of view. The structure is cut into repetitive modules which can be prefabricated off site. Balloon framing is minimized to the elevator/staircase cores, which makes assembly by crane easier, while allowing for quicker installation times of individual panels.
As we move on we will develop other concepts relating to our earlier massing concept (V2, V3) which will reach targets of 16-18 stories with different timber hybrid construction methodologies.
