DIFFERENT CONSTRUCTION METHODS
| 3D VOLUMETRIC | 2D VOLUMETRIC | CONVENTIONAL |
divided into modular units or delivered as a whole project Higher quality achievement in complex and large projects Large productivity gains with lower waste Higher safety in production and on-site assembly Tangible project schedule and shorter delivery times 90% development is Off-site 95% fit-out work is Off-Site Highly Flexible and relocatable to other locations | divided into different section walls and delivered to site for assembly Reduction in quality due to large tolerances Lower productivity due to time waste on-site Safety levels in production are OK but Moderate Safety On-Site Project deadlines are flexible and prone to delay 50% development is Off-site 10% fit-out work is Off-Site Lower Flexibility and not easy to relocate to other locations | Project is developed stage by stage on site Quality of project difficult to be controllable Poor productivity due to uncertainty in each stage Higher risk for workers as all of the tasks are done On-Site Deadlines for project are revised often and delays are expected 0% construction is Off-site 0% fit-out work is Off-Site Rigid Structure and not relocatable to other locations |
