Long-span precast concrete structures and multi-storey residential buildings require a contractor with specialised experience. Our precast system handles spans up to 20–30 metres and delivers consistent quality across every residential unit.
Precast concrete work requires a contractor with specialised experience. Our engineering team manages both long-span and residential structures — from design and factory production to on-site installation in Bangkok.
Long-span structures with no centre columns. Maximises usable floor space. Beams up to 20–30 metres. Ideal for warehouses, factories, auditoriums, and sports facilities in Bangkok. View Details
Precast residential buildings — condos, dormitories, apartments. Every unit produced from the same moulds for consistent quality. Faster construction than cast-in-place. Uniform quality throughout your Bangkok project. View Details
Choosing the wrong contractor for precast concrete work means substandard structures and runaway costs. Here is what you control when you choose I Building:
No external suppliers for main components. Quality control and delivery are in our hands, not someone else's.
Engineers supervise from design through installation. Single point of responsibility — no multi-party coordination.
Contracts define both price and timeline upfront. No mid-project cost overruns. Your risk is minimised.
Precast construction requires specialised expertise that differs from general concrete work — understanding factory production, transport of large components, and precision installation techniques. At I Building we have our own factory and engineering team specialised in precast work exclusively.
Our long-span precast beams span up to 20–30 metres without centre columns. Load capacity meets industrial standards and depends on structural engineering design. Suitable for warehouses, factories, auditoriums, sports halls, and open-plan spaces.
Precast residential buildings are ideal for condos, dormitories, apartments, and multi-unit housing requiring consistent quality across every unit. Components are produced from the same moulds, delivering identical quality and eliminating the variation found in cast-in-place work.
Per-unit cost of precast components may be slightly higher than cast-in-place concrete, but when accounting for lower labour costs, shorter construction time, and reduced interest during construction, the total project cost is comparable to or lower than traditional methods.
We serve Bangkok, Bangkok, Nonthaburi, Pathum Thani, Samut Prakan, and Prachin Buri. Our factory is in Nonthaburi, making component transport efficient for all nearby project locations.
