National Building Code Sectional Committee, CED 46

This Code (Part 0) covers guidelines to be followed for judicious implementation of the provisions of various Parts/Sections of the National Building Code of India following an integrated approach.

In order to provide safe, healthy and sustainable habitat, careful consideration needs to be paid to the building construction activity. Building planning, designing and construction activities have developed over the centuries. Large number of ancient monuments and historical buildings all over the world bear testimony to the growth of civilization from the prehistoric era with the extensive use of manual labour and simple systems as appropriate to those ages to the present day mechanized and electronically controlled operations for designing and constructing buildings and for operating and maintaining systems and services. In those days, buildings were conceptualized and built by master builders with high levels of artisan skills. Technological and socio-economic developments in recent times have led to remarkable increase in demand for more and more sophistication in buildings resulting in ever increasing complexities. These perforce demand high levels of inputs from professionals of different disciplines such as architecture, civil engineering, structural engineering, functional and life safety services including special aspects relating to utilities, landscaping, etc, in conceptualization, spatial planning, design and construction of buildings of various material and technology streams, various services including operation, maintenance, repairs and rehabilitation aspects throughout the service life of the building.

This Code, besides prescribing various provisions, also allows freedom of action to adopt appropriate practices and provides for building planning, designing and construction for absorbing traditional practices as well as latest developments in knowledge in the various disciplines as relevant to a building including computer aided and/or other modern sensors aided activities in the various stages of conceptualization, planning, designing, constructing, maintaining and repairing the buildings. India being a large country with substantial variations from region to region, this Code has endeavoured to meet the requirements of different regions of the country, both urban and rural, by taking into consideration factors such as climatic and environmental conditions, geographical terrain, vulnerability to natural disasters, ecologically appropriate practices, use of eco-friendly materials, use of appropriate conventional and alternative technologies, reduction of pollution, protection and improvement of local environment and also socio-economic considerations, towards the creation of sustainable human settlements.

This Part of the Code dealing with ‘integrated approach’ gives an overall direction for practical applications of the provisions of different specialized aspects of spatial planning, designing and construction of buildings, creation of services, and proposes an integrated approach for utilizing appropriate knowledge and experience of qualified professionals, right from the conceptualization through construction and completion stages of a building project and indeed during the entire life cycle. The ‘integrated approach’ should not only take care of functional, aesthetic and safety aspects, but also the operational and maintenance requirements. Also, cost optimization has to be achieved through proper selection of materials, techniques, equipment installations, etc. Further, value engineering and appropriate management techniques should be applied to achieve the aim set forth for the purpose of construction of a building fully meeting the specified and implied needs of spatial functions, user requirements, safety and durability aspects, life and health safety, comfort, services, etc, in the building. Integration among various professionals/services may be facilitated by use of appropriate software, systems, tools, simulations, etc.

The aim of the ‘integrated approach’ is to get the maximum benefit from the building and its services in terms of objectives such as quality, timeliness and cost-effectiveness. In the team approach which is an essential prerequisite for integrated approach, the aim clearly is to maximize the efficiency of the total system through appropriate optimization of each of its sub-systems, and ensuring coordination among various disciplines and agencies that are involved during planning, design, construction, operation and maintenance of buildings and the associated infrastructure. In other words, in the team, the timely inputs from each of the professional disciplines have to be so optimized that the total system’s efficiency becomes the maximum. It may be emphasized that maximizing the efficiencies of each sub-system may not necessarily assure the maximization of the efficiency of the total system. It needs hardly to be stated that specified or implied safety will always get precedence over functional efficiency

and economy. Further, progressive approach such as that relating to the concept of intelligent buildings would be best taken care of by the ‘integrated approach’ as laid down in this Part.

The continued effort towards development may progressively be aimed at leading us to achieve better and smarter solutions, such as through development of smart cities encompassing sustainability apart from utilizing optimum resources and delivering through intelligent ways, the various facilities and amenities. The integrated approach enshrined in this Part is of immense help in achieving the objective of such smart buildings and cities. It goes without saying that the objective of sustainable development as professed in Part 11 ‘Approach to Sustainability’ of the Code can be best achieved through such an integrated approach.

Proper construction management and certification covering the various dimensions brought out above may go a long way in achieving the above goal of real integrated approach.

This Part was first introduced in 2005 as an adjunct to various other Parts/Sections of the Code. Based on the experience gained in the use of this Part, this revision has been brought out. The significant modifications incorporated in this revision include the following:

a) List of professionals who may be part of multi-disciplinary teams has been updated.

b) Considering the latest provisions relating to construction project management now included in the Part 7 ‘Construction Management, Practices and Safety’ of the Code, the provisions in this Part relevant to construction project management functions have been accordingly updated.

c) Various considerations to be taken care of by the design teams, project/construction management team, and operation and maintenance team have been further reinforced considering the present day requirements and expectations from buildings and built environment.

d) Provisions relating to operation and maintenance have been further extended to include decommissioning and deconstruction (including demolition) to give importance to planned decommissioning and deconstruction after the useful service life of the built facility is over.

e) With the introduction of the new Part 11 ‘Approach to Sustainability’ of the Code, appropriate references to sustainability wherever relevant to the integrated approach, have been taken care of.

f) Accessibility and universal design for ensuring barrier free environment for persons with disabilities has been emphasized by further reinforcing the provisions to this effect appropriately.

g) Annex A giving brief details of the coverage of various provisions under different Parts/Sections of the Code, has been updated, considering modification in the scopes of existing Parts/Sections and inclusion of new Parts/Sections.
