General Information
Common Advantages of Precast Façade
Precast products are manufactured in a facility where critical variables including mix design, weather conditions, temperature, and consolidation can be closely monitored and controlled. This allows the finished quality of precast to far exceed concrete cast-in-place at the job-site or other materials available for use.
| Some Advantages of Precast Construction will include: | |
| 1. Better Quality Control | Since the components are being manufactured off site at factories, higher quality control can be ensured by the pre-casters. |
| 2. Economical Advantage | Due to the higher repetition of the components and the repeated usage of the mould at the factory, economy of scale can be achieved and thus savings in cost of production can be achieved too. |
| 3. Design Advantage | Despite much rumors that precast facades are often dull and common, it is on the contrary, can be nicely and beautifully pre-casted with sophisticated moulds in the factories. |
| 4. Manpower Advantage | Pre-casting allows the decrease in the number of labour on site. |
| 5. Time Advantage | The concept of Just-in-Time construction can be fully exploited and the installation of precast components can be done much faster in comparison to the traditional method of cast-in situ. |
| 6. Neater Sites | Sites coordination can be much easier and neater due to the nature of Dry Construction for precast construction. |
