The industrialization of building construction is gradually becoming a new choice of construction technology driven by some great advantages such as high efficiency in construction, low energy consumption and environmental friendliness. Construction management plays an important part to ensure the quality of projects. A comparison between traditional on-site and modern off-site construction methods has been conducted. The streamlining of the process including the fabrication, transportation, stacking and assembling of precast components has also been analyzed with a discussion on the BIM application in the process.
Remarkably influenced by the ambient temperature and other factors
Prefabricated components can be directly assembled on site
Quality control
Hard to find an agreed standard for various situations
Quality can be easily controlled through joint connection with fixed size components
Shape flexibility
On-site construction is often applied for buildings with complicated designs
Buildings are relatively alike due to fixed scale
Construction management
Complex management of material stacking, human resources and safety
Lean logistics can reduce the material stacking dramatically and help simplify the management on site
Resource consumption
Low efficiency of resource usageHuge energy consumption
Industrialization of components increases the efficiency of resource usageA specified factory is usually needed
Environmental friendliness
Noise and pollution influence the ambient environment greatly
Rare noise and pollution hence moreenvironmentally friendly
Construction function
Special processes need to be applied for water and fire protectionLower construction efficiency
Components of specified functions are precast in factoryLower construction difficulty
Structure performance
Better performance in integrality and stability
Relatively weaker in stability and earthquake-resistance
