Is Interlocking Bricks IBS?








Is Interlocking bricks system an IBS?


What is IBS?

The term Industrialised Building System (IBS) is defined by the Construction Industry Development Board (CIDB) as construction technique in which components are manufactured in a controlled environment (on or off site), transported, positioned and assembled into a structure with minimal additional site works. The term is however, cover very wide scope which include the application of onsite systems and one can not distinguished it properly with conventional practice.

While other terms used to represent construction industrialisation globally are often relates to innovative solution, current definition by CIDB includes low-tech solutions and other of practices which already become common and not substituting conventional practices. The terms and classifications provided by the CIDB were also misinterpreted as a system limited only for construction of buildings, while IBS can be interpreted as an approach or process used in making construction less labour-oriented and faster as well as fulfilling quality concern.

To move forward, the definition on certain system should be revised and improvised as the new innovation are keeping evolved time to time. It is time for the industry to accept the new innovation product which has same or better advantages with other IBS product. The industry must move towards greater mechanisation that has twin effects of increasing productivity and reducing labour requirement.

To redefine IBS, one should look into the existing definitions and other definitions within the context of IBS. Definitions of IBS from 20 literatures of local and international researchers from 1971 – 2009 is therefore need to be studied.

The analysis on IBS definition from the literatures (20 literatures from 1971 -2009) revealed that IBS is not necessarily restricting its scope to the final product which is a system but it could involve the processes which lead to the production of the system and its construction application.

IBS is also not about sizing and dimension. The use of Modular Coordination (MC) nonetheless is encouraged to improve constructability and standardisation.

From IBS definitions (20 literatures from 1971 -2009), the characteristics of IBS are as follows;
Industrialised in production,
Transportation and assembly technique,
Fabrication and mass-production,
Structured planning and standardisation
Process integration

Is it IBS?

Based on the characteristics of IBS, the preliminary analysis are as follows:

Industrialised production – Interlocking bricks is produce offsite using the machineries and industrial prefabrication. Industrial prefabrication for building products by way of industrial technique. This is in line with government aspiration to move towards mechanisation, automation and robotics.

Transportation and assembly – Interlocking bricks is normally transported from factory to site for assembly.

Fabrication and mass-production – Produce in a factory or offsite with superior quality control, accuracy in manufacture provides speed of construction & job site accuracy.

Structured planning and standardisation - The use of interlocking bricks was in line with MC is a concept of coordination of dimensions and space where buildings and components are dimensioned and positioned in a basic unit or module known as 1M which is equivalent to 100 mm, as stipulated in MS 1064. Dimension accuracy up to ± 1.5 mm.

Progress integration - The use of modular coordination and standard sizing allow flexibility to integrate with other IBS system thus encourage participation from manufactures and assemblers to enter the market, thus reducing the price of IBS components.

Therefore, method, approach and process of constructing building using interlocking bricks in general has similarity to IBS product which has same or better advantages with other IBS product.


Innovation attributes of Interlocking bricks

The construction method of using conventional bricks has been revolutionised by the development and usage of interlocking system. The tedious and time-consuming traditional brick-laying tasks are greatly simplified by the usage of these effective alternative solutions.

Interchangability concepts towards the adoption plug & play concepts which offers flexibility for the products to integrate with other IBS system

The processes of producing the material incorporates the concept of mechanisation

The process of production promotes the adoption of sustainable construction with generate only minimal material wastage mean less clean up at site.

The final product gives excellent heat and sound insulation contribute to environmental friendly and energy saving

Ease of renovation (DIY concept) construction and house extension works (not required crane)

The bricks can act as wall panel in combination form at factory (high IBS Score)

As oppose to normal brick, interlocking bricks has interlocking system comparable to LEGO system. The tedious and time-consuming traditional brick-laying tasks are greatly simplified by the usage of these effective alternative solutions. It also allows accuracy up to ± 1.5 mm.

General benefits

Small players lack financial backup and not able to set up in-house manufacturing plants as it involves very intensive capital investment and need to cover the amortised cost of setting up a prefabrication yard, as well as the variable costs of manufacturing components and of their on-site assembly.

Therefore, IBS system in Malaysia shall not be limited to high advanced technologies and mass-production concept. The Interlocking bricks system is one of the simplest, flexible and most versatile systems that can be used by many in the industry. The followings are benefits of encouraging Interlocking bricks as part of IBS:

In applying pre-cast construction, enormous capital cost would involve which include set up the plant, supplying machinery and moulds A brick system offers some sort of low cost IBS with low capital investment, where many contractors and manufactures (especially Bumiputera) can be involved in the industry.

Interlocking bricks is the easiest way of adopting IBS and can easily penetrating construction market. However, there is need for skilled designers to design engineering brick than can capitalise the benefit of IBS. The engineering brick system depends on modular dimension at design stage, is also comparable to LEGO system.

The use of modular coordination and standard sizing allow flexibility to integrate with other IBS system thus encourage participation from manufactures and assemblers to enter the market, thus reducing the price of IBS components

Interlocking bricks applies load bearing wall by incorporating the columns and beams as integral part of the wall for all types of houses (up to 5-storey in high). The amount that can be saved on a wall can range from 10% to 30% as compared to conventional with additional less foundation cost. The save in cost is in line with one of the IBS Roadmap 2011-2015 pillars which is to create a financially sustainable IBS industry that balances users’ affordability and manufacturers’ viability. Suitable for mass- produced, affordable housing program.

Interlocking bricks give up to 3 times faster in construction of walls, columns & beams compared to conventional method. Faster construction give a major advantage to commercial clients and sopporting government policy to build 10,000 affordable housing in 2012.

The Results

The definition of IBS on certain systems should be revised and improvised as the new innovation are keeping evolved time to time. IBS is also not about sizing and dimension.  It is time for the industry to accept new innovative product which has same or better advantages with other IBS product.

The Interlocking bricks system is one of the simplest, flexible and most versatile systems that can be used by many in the industry.

This preliminary report recommends that based on its characterisation, benefits and innovation potential of interlocking bricks, it should be given consideration by CIDB to be included as one of IBS product under innovation/hybrid cluster.

Thank god I found your blog. It is really helping me to answer most of my question in Interlocking Bricks.
