Assembly regime is a set of rules, conditions and sequence of technical actions to be followed during the assembly of building elements in order to ensure the correct operation of the structure. It is defined at the design and technical documentation stage and its a breach may lead to uncontrolled deformation or overloading of the structure.
It includes requirements for the order in which the components are joined, how they are supported, how they are temporarily braced and how they are position controlled during assembly. It is closely related to the adopted structural system and assembly tolerances.
In modular construction, the assembly regime often incorporates phased load transfer between modules as the work progresses. Its observance is crucial to the safety of the installation and to the achievement of the building's load-bearing capacity and stability on completion.
