Topic Covered in this article: Modular Coordination, Basic Module, planning and design modules, & Modular grid system
1. Assembly of single components into large components.
2. Fewest possible different types of component.
3. Minimum wastage of cutting needed.
The planning grid in both directions of the horizontal plan shall be
The centre lines of load bearing walls shall coincide with the grid lines
Optimized number of standard sizes of element to building design
Modular coordination means the interdependent arrangement of a dimension based on primary value accepted as a module. The strict observance of rules of modular coordination facilitated,
1. Assembly of single components into large components.
2. Fewest possible different types of component.
3. Minimum wastage of cutting needed.
Modular coordination is the basis for a standardization of a mass production of component. A set of rules would be adequate for meeting the requirements of conventional and prefabricated construction.
Basic Module: The fundamental module used in modular construction . The size of which is selected for general application to building and component. The value of the basic module is 100mm for maximum flexibility and convenience.
The symbol is M and 1M = 100 mm.
Multi Module: They are standardized selected whole multiple of basic module. By using multi module it is possible to achieve a sustainable reduction in the number of modular sizes. Components have same dimension equal to the same dimension of its functional element.
- To reduce the variety of component size produced
- To allow the building designer greater flexibility in the arrangement of component.
The planning grid in both directions of the horizontal plan shall be
- 3M for residential and institutional buildings,
- For industrial buildings,
- 15M for spans up to 12m
- 30M for spans between 12m and 18m
- 60M for spans over 18m
The centre lines of load bearing walls shall coincide with the grid lines
- In case of external walls the grid lines shall coincide with the centre line of the wall or a line on the wall 5 cm from the internal face of the wall
- The planning module in the vertical direction shall be 1M up to and including a ht of 2.8M.
- Preferred increments for the still heights, doors, windows and other fenestration shall be 1M.
Modular Grid — A rectangular coordinate reference system in which the distance between consecutive lines is the basic module or a multi-module. This multi-module may differ for each of the two dimensions of the grid.
- Continuous Grid (all dimension same + increment 1M)
- Superimposed Grid (Modular Superimposed on Multi Modular, 1M on 3M)
- Displacement of Grid (homogeneous and repetitive relation between at least two basic increment, 1M2M3M1M2M3M )
- Interrupted Grid/ Netural Grid (Non modular interruption zones are created to cope economy)
