They don't strike their blockwork , because it is so atrocious that they cover it with render , welcome to the Philippines , 

That's correct really.  You don't want to leave the block exposed to the rain so you know it's going to be rendered anyway.

On the subject of masonry though, how do you do the raised mortar?  I've seen it some here and some in older building in the UK, etc.  It's usually on stone and the mortar protrudes from the wall maybe a half inch or so rather than being recessed.  Sort of like this:

http://www.understandconstruction.com/concrete-frame-structures.html Concrete block, being used as infill or partition, isn't designed to be part of the structural integrity of a pillar and beam

@A_Simple_Man @Kabisay-an gid @shadow  I thought this worthy of it's own thread , and will save the back and forths about fence construction in "the bad guy's" thread. I have borrowed Dave's

Here is another example of clueless activity , all they had to do was use a chicken mesh or similar to help keep this together , but on goes the concrete without anything to keep it binded together ..

It is just mortar trowelled onto the joints , pronounced , then just cut off the excess while wet with the trowel, and clean the block or stonework with a wet sponge , the sponge can also be used to smooth off and finish the pronounced joint , a damp sponge does wonders on finishing concrete if you have a curved surface as well , like a curb.

It is actually scary to see such little structural knowledge embarking on a project like this , it looks like only 2 main concrete columns on each front corner were in place to take the load of that floor and whatever else was meant to be going on ontop of that floor as well ...if the flimsy coco lumber/bamboo formwork support had not of collapsed under the weight of the wet concrete you would have to think that the first decent tremor from the ground would have taken the building out anyway....

Looks like everyone got out ok unless there were some underneath when it fell.  One guy was close enough to the edge to hang on and climb back up.  About 5 walk out to the right.  One guy is moving on top of the pile (he had the longest ride starting at the left edge and ending up about a third of the way to the right) and another walks back in (maybe to help the guy on top).

The edge beams on top failed easily and it appears there were 2 others going out to the front beam that failed starting the collapse.  I would agree that 2 columns wasn't enough but I also figure they didn't cure the beams long enough.
