Modular assemblies and methods of construction thereof

A method of fabricating a modular assembly, comprising:

• providing first and second prefabricated modular frames of respective first and second modular assemblies;
• fixedly coupling a first wall of a first formwork of the first modular assembly to a first side of the first modular frame;
• coupling a reinforcing bar cage of the first formwork to the first side of the first modular frame, such that the first wall is disposed between the reinforcing bar cage and the first modular frame;
• coupling a second wall to the first wall;
• attaching a first end of at least one connector to the first side of the first modular frame;
• directly attaching a second end of the at least one connector to a portion of the reinforcing bar cage that is between the first and second walls;
• stacking the second modular frame on a ceiling of the first modular frame, such that a second formwork of the second modular assembly is disposed on top of the first formwork;
• pouring concrete into the first and second formworks;
• and
• detaching the second wall from the first wall after the concrete is poured into the first and second formworks.

A modular assembly for forming a shear wall, the modular assembly comprising:

• a modular frame of a habitable modular unit, the modular frame including a floor and an opposing ceiling and first and second lateral sides interconnecting the floor and ceiling, the modular frame having a first side and a plurality of shafts extending laterally from the first side of the modular frame;
• formwork including:
• a first wall coupled to the first side of the modular frame;
• and
• a second wall spaced from the first wall and configured to be coupled to an end of each of the plurality of shafts;
• and
• at least one connector interconnecting the modular frame and the formwork, wherein the modular frame and the formwork are together configured to be stackable with a modular frame and a formwork of another modular assembly, such that a hardening material is pourable into both modular frames of the stacked modular assemblies, the second wall being configured to be detachably coupled to the first wall, such that the second wall is detached from the first wall after the hardening material is poured into both modular frames of the stacked modular assemblies.
