Where projects have significant numbers of repeatable elements it provides opportunity for modularised components to be constructed off-site in controlled factory conditions prior to deliver to site where it is integrated into its final location. Volumetric modular construction (VMC) requires a clear staged process to ensure successful project delivery, including;
- Detailed planning and design utilising the principles of design for manufacture and assembly (DfMA) which implements lean manufacturing principles and production theory to develop repeatable components.
- Manufacture of the modules under controlled conditions ready to transport to site.
- Modules are transported to site in accordance with a detailed installation schedule, on arrival they are lifted into location with the assistance of the site tower crane into their final location.
- Once located the modules are in position and are tied together using connectors to form the building.
Generally, the off-site modular elements in high-rise construction are integrated with the traditional in-situ concrete structure commonly forming the basement, podium and services core.
