Building Materials
and Technology Promotion Council
TN Gupta
Since
its inception in 1990, the Building Materials and Technology
Promotion Council (BMTPC), an inter-ministerial organisation under
the aegis of the Ministry of Urban Affairs and Employment, has been
engaged in promoting development of indigenous technologies based on
optimum utilisation of local resources. These technologies cover
products, processes and techniques. BMTPC, as an interface and
promotional organisation, has established operational links with a
number of Central and State Ministries/Departments, R&D
organisations and a lot of other institutions, agencies and NGOs
which have a stake in the housing and building sector particularly
and the overall construction sector generally.
The Council has pursued a range of activities
which have been disseminated through annual reports, and a large
number of other user-friendly publications, brochures, technology
packages, newsletters etc. With increasing interaction and rising
expectations of related departments, organisations and agencies, the
Council has lately restructured its thrust areas and scope of
activities based on better understanding of the building sector and
changing scenario of the construction industry in the context of
economic liberalisation policies and programmes. The activities of
BMTPC currently focus on the following areas :
► |
Developing
interaction and collaboration with R&D, academic institutions
and commercial sections of foreign missions for selection and
evaluation of appropriate building material technologies; |
► |
Identification of
appropriate technologies for waste utilisation, wood
substitution, upscaling of bench level technologies; |
► |
Providing
technical/financial support for technology upgradation and
back-up services to potential entrepreneurs and building centres
in rural and urban areas; |
► |
Studies on
region-specific needs and identification of areas for technology
intervention to promote cost-effective building materials and
technologies; |
► |
Enhancing production
of building materials and components by facilitating
entrepreneurial activity with the help of industrial promotion
and financial institutions; |
► |
Promoting the
incorporation of new materials and technologies in actual
construction practices, schedules of specification and
standards; |
► |
Assistance for
improving policy, finance and investment climate for
entrepreneurs ; |
► |
Promoting disaster
resistant construction practices - with reference to cyclones,
floods; and |
► |
Strengthening
technology transfer, training, demonstration and information
dissemination systems in urban and rural areas. |
Measures taken by BMTPC to
Promote Large Scale Use of Cost Effective Construction Technologies
and Building Systems
Standards and
specifications for Cost-Effective innovative Building
Materials/Components and Construction Systems:
The scarcity, frequent non-availability,
constantly rising costs of building materials and declining quality
of housing construction have been causing concern to Central and
state governments. Despite a number of innovative energy efficient
and low cost building materials and construction techniques
developed by R&D institutions, these technologies have not been
adopted in common construction practice. Lack of standards and
specifications has been generally cited as the main factor coming in
the way of wide scale adaptation of these innovative technologies.
BMTPC took up the task of formulating
specifications on identified cost-effective building materials,
components and construction techniques which have the potential for
large scale adoption and bringing down the cost of housing and
building construction. Several of these items were not so far
covered by Indian standards and codes of practice. After the
specifications were formulated by BMTPC, now available as a
Council’s publication, titled "Standards and Specifications for
Cost-Effective Innovative Building Materials and Techniques", the
formulation of Indian standards and codes was taken up with the help
of concerned Sectional Committees of the Bureau of Indian Standards
(BIS). The Central Public Works Department has also incorporated a
majority of these items in their schedules of specifications. The
state governments of Orissa and Kerala have taken the lead in
adopting many of these technologies. The Rajasthan Housing Board has
also incorporated a number of these technologies in their schedule.
Utilisation of Industrial Wastes
(Flyash, Phosphogypsum, Red-mud)
To encourage wide-spread production of flyash
based building materials, BMTPC is closely interfacing with the
Departments of Environment, Power, Central Electricity Authority,
R&D Organisations, State Housing Finance Organisations and
entrepreneurial community all over the country. At the national
level, substantial progress has been achieved in terms of creating
awareness about the techo-economic advantages of conversion of
wastes/by-products like flyash and phosphogypsum into need based
building materials. The following are some of the indicators of
progress achieved so far in different regions:
► |
Services rendered by
BMTPC help in promotion of waste utilisation through technology
generation and upgradation, facilitation of financial assistance
for setting up material manufacturing plants and technical
consultancy. BMTPC has been closely interacting with various
thermal power plants in order to assist them in preparing action
plans for utilisation of flyash. |
► |
At the instance of
the Council, the Government of India has given excise duty
exemption on materials and products using 25 per cent or more of
flyash and phosphogypsum as raw materials along with several
other waste based building materials. Custom duty exemption has
also been given on critical machinery required to be imported
for manufacture of materials/components from flyash and
phosphogypsum. |
► |
The regions activated to go in for building
materials manufacturing plants using flyash are Delhi, Andhra
Pradesh, West Bengal, Uttar Pradesh, Gujarat and Karnataka.

Directory of Indian Building
materials and Products 1996-97 with information of Nepal and Bhutan
In response to the fast expanding construction
sector and pace of industrialisation, a large variety of building
materials and products are being manufactured and supplied in the
Indian market. But there is a large demand for information about new
products. Recognising the need of professionals for possible
applications in the buildings, a Directory of Indian Building
Materials and Products 1996-97, with information on Nepal and
Bhutan, has been brought out by the Council in collaboration with
the Centre for Symbiosis of Technology Environment and Management.
The Directory was released by the Prime Minister of India on the
occasion of World Habitat Day 1996. Besides providing information
pertaining to technical aspects and availability of different
building materials, the Directory presents data relating it to
Indian standards, specifications and manufacturing status of
materials. New building materials and construction technologies
developed by leading R&D organisations in the country have also been
included.
Development of Machines for
production of Building Materials and Components
In order to promote production of cost-effective
building materials and improve their availability in different
regions, the following machines have been developed under the
sponsored programme of the Council:
► |
a machine for
production of RCC door and window frames, lintels, chajjas
(completed) |

Setting up of Production Centres
for manufacture of cost-effective building components
As a part of promotional efforts, the Council is
keen to set up production centres in different regions to
demonstrate and manufacture innovative and cost-effective building
materials and construction technologies. Such facilities are being
set up as a unit of the Council by the state or local agencies,
building centres or voluntary organisations which are in a position
to provide demonstration and training to disseminate the benefits of
cost-effecive technologies among local people. The Council has
supported establishment of more than 25 such production centres in
the country. These production centres not only strengthen the
production of cost-effective building components but also improve
their availability in different regions.
Development of Wood Substitutes
The Council has developed a technology for
utilisation of rubber-wood in making door/window frames and shutters
according to Indian standards. The final product has already been
tested as per standards and has been found suitable for use in
buildings. Another type of door frame and shutter has been developed
based on the use of Poplar wood. The properties of Poplar were
elevated for producing flush doors; panel doors and door frames. The
technologies have been transferred to entrepreneurs for production
at commercial level. The Council has also developed door shutters
from Rubber-wood and polystyrene core, and rigid PVC foam board for
use as core for door shutters, panels and partitions. The final
products have been tested in the laboratory and the technology is
ready to be transferred for commercialisation.
Disaster Resistant Construction
The Council in the
past has been providing technology backup services by developing
guidelines for design, construction and retrofitting of different
types of non-engineered and semi-engineered residential buildings.
Last year, a major initiative was taken for preparation of
Vulnerablity Atlases for different states and union territories in
the country. These atlases, which are being prepared on a state-wise
basis, indicate areas vulnerable to earthquakes, cyclones and
floods. The atlas contains hazard maps indicating different
intensity zones and the level of risk that existing housing stock is
exposed to. The level of risk has been worked out with reference to
the walling and roofing types adapted in different geo-climatic
regions. With the help of this information, proper action can be
taken by district adminstration to formulate pre-disaster and
post-disaster strategies.
BMTPC Directory of Construction
Equipment and Machinery Manufactured in India
This publication fulfills a long standing need to
create a national inventory for sourcing construction machinery and
equipment manufactured in India. With the projected rise in the
volume of the construction activities and fast increasing
mechanisation, the role of equipment and machinery in construction
is becoming crucial. The present Directory covers the corporate and
product profiles of nearly 600 equipment manufacturers in India. A
list of selected international manufacturers has also been included.
Fiscal Concessions for Production
and Adoption of Cost-effective Building Materials
To stimulate
increased production of cost-effective building materials,
components based on utilisation of industrial and agricultural
wastes and construction technologies, the Council has been assisting
the government in formulating a package of fiscal incentives. As a
result, the government has given various concessions and fiscal
incentives during the Union Budget. In this manner, BMTPC has been
fulfilling its commitments to the promotion of improved, efficient
and cost-effective building technologies.
