The scheme builds on the modular system developed by ADDP Architects, who designed the buildings using Prefabricated Prefinished Volumetric Construction (PPVC). 66% light 200 pen bitumen + 14% light creosote oil + 20% solvent naphtha The concrete shall be of C28/35. shall be laid at entrances and junctions. The cable warning marker shall cover the full width of the UPVC pipes.

There are 3 types of PPVC system available in the market;. However, PV modules deployed in tropical regions face a different set of environmental conditions than PV modules deployed in temperate regions where the majority of today's PV markets exist.
