ICC Modular building solutions using PPVC technology that facilitates off-site fabrication. Modules made of multiple units, complete with internal finishes, fixtures and fittings are transported to site and installed in a Lego-like manner. PPVC systems have been widely adopted in low, medium and high rise buildings throughout the world, especially in densely-populated countries like Singapore, USA, Malaysia and Hong Kong. Such systems will resolve the anticipated manpower shortages in the construction industry to a great extent, thereby supporting enhanced sustainability.
