It will be the same problems that were occurring before there were so many dorms.
Foreign workers were congregating, eating, drinking, littering, and urinating in the HDB estates.
The 4G team is not solving problems but creating the same problems.
Building dorms near HDB flats accomplishes nothing. Just some stupid politician virtue signalling about how the precious foreign workers are part of the Singapore family/story etc, so they should be allowed to mingle with the locals who in turn should appreciate their contributions to nation-building etc.
