MODULAR CONSTRUCTION

BSB 602

Modular vs. Standard Construction (Conventional)A modular building is a pre-engineered structure that is flexible enough to satisfy virtually any requirement... tougher than standard drywall construction, expandable, can be relocated and completely re-usable.

One obvious advantage that modular construction has over conventional construction is cost. Not only can one save up to 35% on the initial construction costs like labor and materials, but there are other benefits as well.

MODULAR CONSTRUCTION

With increasing industrialization to the building industry, steadily larger parts of buildings are made up of prefabricated components, delivered to the building site from the factories.

Evidently, some sort of dimensional coordination of these component themselves and with the design are of paramount importance.

The full benefit of the industrialization is impossible without standardization. No effective standardization is possible in the building industry, without dimensional coordination.

BSB 602

Modular coordination is a concept of coordination of dimension and space in which buildings and components are dimensioned and positioned in terms of basic unit or module.

The basic module is known as 1M which is equivalent to 100mm.

It is internationally accepted by the International Standard Organisation and many other countries including Malaysia.

• Industrialization friendly i.e. able to cater for manufacturing, transportation and assembly requirements.

• Small enough in term of size in order to provide the necessary flexibility in design.

• Large enough to promote simplification of the number of sizes for various components.

• Internationally accepted to ensure that it can be mass produced to cater for global market.

• Ergonomic i.e. able to improve people efficiency by providing adequate space for human livings and working conditions.

• It provides a practical and coherent: method for coordinating- the position and dimension of elements, components and spaces in the planning and design of buildings.

• To improve productivity in the building industry through industrialization. MC can facilitate the achievement of industrialization.

• Provide guide to building component sizing: this can reduce as much as possible the needs to further trim and shape the materials to fit together in construction; thus, reducing wastage of labour and material.

• Mass production of building components factories: thus, ensuring good and consistent of workmanship and quality.

• To permit standardization, which encourages the use of standardized building components for the construction of different types of building; to simplify site operation by rationalizing setting out, positioning and assembling of building components at the site.

• To ensure dimensional coordination between installation (equipment, storage units, other fitted furniture etc) as well as with the rest of the building.

• To encourage open systems: the interchangeability of components, whatever their material, form or method of manufacture,

• CIDB encourages the standardization and improvement of construction techniques and materials in line with its role in Malaysian construction.

• It is also to promote and stimulate the development, improvement and expansion of the construction industry.

How can Modular Coordination improve productivity?

Facilitates the attainment of three objectives of all industrial developments:-

• mass production of selected components by specialist firms thus achieving economy of scale

• the components can be sold on the open and possibly international market as they are of standard dimensions; and

• other specialist firms can concentrate on the assembly of components into a final consumers products.

1 - DIMENTIONAL CO-ORDINATIONA convention for the co-ordination of the dimensions of building components and building incorporating them in their design, manufacture and assembly by means of a three dimensional spatial references system points, lines and planes to which the position and size of a components, assembly of element may be related.

MC ConceptMC ConceptThe dimensional coordination is essential in order to:-

• simplify design and documentation procedures and allow the implementation of computer techniques;

• achieve optima efficiency in the manufacture and use of components and assemblies;

• avoid cutting or modifying components andassemblies on site;

• standardize the profile and detail of jointsbetween components;

• Reduce non-standard or dimensionallyincompatible components and assemblies; and

• maximize the Interchangeability of components and assembliesBSB 602

2 - MODULAR CO-ORDINATIONDimensional co-ordination employing the basic module or some whole multiple thereof as basic dimensional unit and increments of it.

The basic module which is generally accepted at an international level is 100mm which may be represented by the letter M.

Modular Reference SystemModular Reference System

In Modular co-ordination:- the term modular reference systemsis the three-dimensional system of orthogonal space co-ordinates within the positions and sizes of components, elements and installations can be related by references to points, lines, or planes.

Within this references system, dimensional increments are in terms of the basic module (100mm) or some multiple thereof.

Reference planes can be identified which locate the main vertical and horizontal elements of construction, e.g. floor, walls, and columns.

Traditionally, modular theory has distinguished between boundary planning and axial planning. In practice, however, such a clear-cut distinction may not exist.

BSB 602

If modern methods of construction are to play a role in addressing the drivers for change they must achieve some or all of the following at least as well as traditional construction:

• Be affordable

• Be of good quality

• Be able to cope with a shortage of skilled labour

• Be available in quantity

• Be capable of responding to changing construction regulations

• Have good environmental credentials
