DETAIL!

For the 1:1 detail, i think i have researched enough of hollowcore floor plank technology to feel comfortable with modelling it at life size. there are several options.

This shows a pre-cast concrete beam with reinforced concrete column. The beam is shaped in a way to allow appropriate bearing for the floor planks.

Alternatively, i can design the building with steel intersecting with the pcp planks instead. Which is probably more suitable to the project requirements. will need to find out minimum depth of the steel beam though as no dimensions are specified in the hollow core detailing manual
