In the above two pictures precast concrete panels can be seen set in place. In particular, it is important to note that below the panels are two white objects used as spacers until the panels are permanently fixed into place. These are called shims.
The above picture shows a horizontal precast concrete panel placed between and resting on the edge of two vertical panels. This panel is acting as a lintel. In the upper and lower corners of the lintel steel screw-in plates have been used to hold it in place temporarily.
The above picture shows a typical floor slab and a black plastic damp proof membrane. The precast concrete panel to the left contains a hole which is used as a fixing point between the precast panel and the concrete slab.
