The image presented is for a sublevel area. The footings are down deep with a load bearing wall supporting the upper floor level. If you did that drain next to the waffle you have just created a zone of influence and created a zone of abnormal moisture next to the slab. ANY movement would be owner related and not covered by QBCC's subsidence policy. First off when the concretor pulled his form work (the timber boards) the black plastic was required to be folded back up against the slab edge. That plastic needs to finish level with finish ground level to prevent moisture in the soil transfering through horizontally into the slab and rotting the frame/carpet etc etc. Second the builder should have back bladed, this is where the excess soil is pushed against the slab edge to create ground that falls out from the slab to prevent water ponding against the slab edge. Third, the stormwater risers the 100mm white pipe sticking up out of the ground, most of those are downpipe points and yard gully points as their are no pipes in the slab near them, so they won't be ORG's for sewer. The stormwater rigid pipes should be cut down at least level or just below the current ground level and flex pipe in a sock connected to the pipe. They can tie a knot in the end of the sock so soil doesn't go down the pipe. This way the stormwater system becomes active straight away (as per the requirements of the BCA, AS2870, the geo's report and the engineers design..just to name a few) and the sites surface water will/can drain.
