Why Modular?

Features Traditional Build [Civil] Modular Prefab Construction (Recommended) Onsite PreFab Construction
Process 100% built on site 90% built in the factory, 10% Onsite work 30% built in factory, 70% built onsite
Quality Quality can vary due to site conditions and labour Higher quality standards with precision workmanship Predictable quality but finishes based on skilled labour
Portability Immovable structures with no options post construction Completely movable structures with option to relocate Semi-Portable structure, can retain 50% of the structure
Sustainability High carbon footprint as multiple teams have to visit all sites Lower carbon footprint as multiple teams have to visit factory Lower carbon footprint than Traditional build
Build Environment Subject to site related conditions Rain, Electricity & Water Independent of site related conditions due to factory environment Subject to site related conditions Rain, Electricity & Water
Raw Material Concrete does not biodegrade for 100+ years MS Steel Modular, Cement board with External ACP or GI cladding Steel Prefab structure with cement board exterior board
Reuse and Resell Cannot be re-used and value of build depreciates every year Can be re-used and very high scrap value. Can be re-used and very high scrap value.
