It is a load-bearing pre-cast concrete structure. This structure is used for support along the bondary walls for a curtain-wall facade of glass that will cover the front, street-facing facades. This is what I gathered from the artist's impression.
Overview of the site from across the road:
View of the site from the inside, including internal pcp walls. They are being propped up, with the props resting on the strip footings on the ground. Steel bars are protuding out of the strip footings in preperation for future connections. In the meantime, they are capped with yellow plastic for safety.
You can start seeing servicing already coming up from the ground, especially plumbing. Infill concrete slab beyond.
Side pcp wall. They have not been joined yet and are still being propped up. Each panel is about 1400 wide.
The other side of the same stretch of wall. Shows the proppping in particular, which is directly bolted to walls and evenly distributed at the same height.
The base of a wall panel on the boundary of the site. There is a space 50 mm space, allowing for space to work and finishing floor to be poured later. Importantly, you can see the shim on which the wall rests in order to make accurate placement of the panel easier. It will remain under the panel and have conrete poured over later.
A close up of the ferrule on the pcp that the crane would have hooked onto during installation. This will be covered up flush with the wall surface later.
This view shows the base of the wall. IN this particular section of the building, it is dug down quite deep into the natural ground. Youc an also see where the strip footings end. It is hard to understand why then would not run underneath the wall themselves and it is not clear what the walls are acutally standing on currently!
PCP with doorway is possible. Note here a control join occurs at the opening as it is a place of weakness, esp during movment.
