[Progress.057] Joined steel beam got new skin

I took some photos yesterday, as shown below the 2 pallets of bricks at the front were gone, some new ones were delivered, probably on Friday.

A closer look at the garage shows they have finished the garage wall, with the windows also installed.

From the side shows the scaffoldings also have some green coloured nets installed to protect neighbour's house.

What I don't understand is, why did they spray orange paint on the joined steel beam. Is this to make it look like the other part??!! What's the point??!!

This one from other side...
