  • 7. FOREWORDConstruction prograrnmes are interwoven in a large measure in all sectors of development, be it housing, transport,industry, irrigation, power, agriculture, education or health. Construction, both public and private, accounts forabout fifty percent of the total outlay in any Five Year Plan. Half of the total money spent on constructionactivities is spent on buildings for residential, industrial, commercial, administrative, education, medical, municipaland entertainment uses. It is estimated that about half of the total outlay on buildings would be on housing. It isimperative that for such a large national investment, optimum returns are assured and wastage in construction isavoided.Soon after the Third Plan, the Planning Commission decided that the whole gamut of operations involved inconstruction, such as, administrative, organizational, financial and technical aspects, be studied in depth. For thisstudy, a Panel of Experts was appointed in 1965 by the Planning Commission and its recommendations are foundin the ‘Report on Economies in Construction Costs’ published in 1968.One of the facets of building construction, namely, controlling and regulating buildings through municipal byelawsand departmental handbooks received the attention of the Panel and a study of these regulatory practices revealedthat some of the prevailing methods of construction were outmoded; some designs were overburdened withsafety factors and there were other design criteria which, in the light of newer techniques and methodologies,could be rationalized; and building byelaws and regulations of municipal bodies which largely regulate thebuilding activity in the country wherever they exist, were outdated. They did not cater to the use of new buildingmaterials and the latest developments in building designs and construction techniques. It also became clear thatthese codes and byelaws lacked uniformity and they were more often than not ‘specification oriented’ and not‘performance oriented’.These studies resulted in a recommendation that a National Building Code be prepared to unify the buildingregulations throughout the country for use by government departments, municipal bodies and other constructionagencies. The then Indian Standards Institution (now Bureau of Indian Standards) was entrusted by the PlanningCommission with the preparation of the National Building Code. For fulfilling this task a Guiding Committee forthe preparation of the Code was setup by the Civil Engineering Division Council of the Indian Standards Institutionin 1967. This Committee, in turn, set up 18 specialist panels to prepare the various parts of the Code. TheGuiding Committee and its panels were constituted with architects, planners, materials experts, structural,construction, electrical illumination, air conditioning, acoustics and public health engineers and town planners.These experts were drawn from the Central and State Governments, local bodies, professional institutions andprivate agencies. The first version of the Code was published in 1970.After the National Building Code of India was published in 1970, a vigorous implementation drive was launchedby the Indian Standards Institution to propagate the contents and use of the Code among all concerned in the fieldof planning, designing and construction activities. For this, State-wise Implementation Conferences were organizedwith the participation of the leading engineers, architects, town planners, administrators, building materialmanufacturers, building and plumbing services installation agencies, contractors, etc.These Conferences were useful in getting across the contents of the Code to the interests concerned. TheseConferences had also helped in the establishment of Action Committees to look into tie actual implementationwork carried out by the construction departments, local bodies and other agencies in different States. The mainactions taken by the Action Committees were to revise and modernize their existing regulato~ media, such as,specifications, handbooks, manuals, etc, as well as building byelaws of local bodies like municipalities at cityand town levels, zilla parishads, panchayats and development authorities, so as to bring them in line with theprovisions contained in the National Building Code of India. In this process, the Indian Standards Institutionrendered considerable support in redrafting process.Since the publication in 1970 version of the National Building Code of India, a large number of comments anduseful suggestions for modifications and additions to different parts and sections of the Code were received as aresult of use of the Code by all concerned, and revision work of building byelaws of some States. Based on thecomments and suggestion received the National Building Code of India 1970 was revised in 1983. (v)
  • 8. Some of the important changes in 1983 version included : addition of development control rules, requirementsfor greenbelts and landscaping including norms for plantation of shrubs and trees, special requirements for lowincome housing; fire safety regulations for high rise buildings; revision of structural design section based on newand revised codes, such as Concrete Codes (plain and reinforced concrete and prestressed concrete), EarthquakeCode, Masonry Code; addition of outside design conditions for important cities in the country, requirementsrelating to noise and vibration, air filter, automatic control, energy conservation for air conditioning; and guidanceon the design of water supply system for multi-storeyed buildings.The National Building Code of India is a single document in which, like a network, the information contained invarious Indian Standards is woven into a pattern of continuity and cogency with the interdependent requirementsof Sections carefully analyzed and fitted in to make the whole document a cogent continuous volume. A continuousthread of ‘preplanning’ is woven which, in itself, contributes considerably to the economies in constructionparticularly in building and plumbing services.The Code contains regulations which can be immediately adopted or enacted for use by various departments,municipal administrations and public bodies. It lays down a set of minimum provisions designed to protect thesafety of the public with regard to structural sufficiency, fire hazards and health aspects of buildings; so long asthese basic requirements are met, the choice of materials and methods of design and construction is left to theingenuity of the building professionals. The Code also covers aspects of administrative regulations, developmentcontrol rules and general building requirements; fire protection requirements; stipulations regarding materialsand structural design; rules for design of electrical installations, lighting, air conditioning and lifts; regulation forventilation, acoustics and plumbing services, such as, water supply, drainage, sanitation and gas supply; measuresto ensure safety of workers and public during construction; and rules for erection of signs and outdoor displaystructures.Some other important points covered by the Code include ‘industrialized systems of building’ and ‘architecturalcontrol’. The increase in population in the years to come will have a serious impact on the housing problem. Ithas been estimated that the urban population of India will continue to increase with such pace as to maintain thepressure on demand of accommodation for them. Speed of construction is thus of an utmost importance andspecial consideration has to be given to industrialized systems of building. With increased building activity, it isalso essential that there should be some architectural control in the development of our cities and towns ifcreation of ugliness and slum-like conditions in our urban areas is to be avoided.Since the publication of 1983 version of National Building Code of India, the construction industry has gonethrough major technological advancement. In the last two decades, substantial expertise has been gained in theareas of building planning, designing and construction. Also, lot of developments have taken places in the techno-legal regime and techno-financial regime, apart from the enormous experience gained in dealing with naturalcalamities like super cyclones and earthquakes faced by the country. Further, since the last revision in 1983based on the changes effected in the Steel Code, Masonry Code and Loading Code as also in order to update thefire protection requirements, three amendments were brought out to the 1983 version of the Code. Consideringthese, it was decided to take up a comprehensive revision of the National Building Code of India.The changes incorporated in the present Code, which is second revision of the Code, have been specified in theForeword to each Part/Section of the Code. Some of the important changes are: a) A new Part O ‘Integrated Approach — Prerequisite for Applying the Provisions of the Code’ emphasizing on multi-disciplinary team approach for successfully accomplishing build$g/development project, has been incorporated. b) New chapters on significant areas like structural design using bamboo, mixed/composite construction and landscaping have been added. c) Number of provisions relating to reform in administration of the Code as tdso assigning duties and responsibilities to all concerned professionals, have been incoprated/modified. Also detailed provisions/ performance to ensure structural sufficiency of buildings, have been prescribed so as to facilitate implementation of the related requirements to help safely face the challenges during natural disasters like earthquake. d) Planning norms and requirements for hilly areas and rural habitat planning, apart from detailed planning norms for large number of amenities have been incorporated. e) Fire safety aspects have been distinctly categorized into fire prevention, life safety and fire protection (vi)

  • 27. National Building Code Sectional Committee, CED 46FOREWORDIn order to provide safe and healthy habitat, careful consideration needs to be paid to the building constructionactivity. Building planning, designing and construction activities have developed over the centuries. Large numberof ancient monuments and historical buildings all over the world bear testimony to the growth of civilizationfrom the prehistoric era with the extensive use of manual labour and simple systems as appropriate to those agesto the present day mechanized and electronically controlled operations for designing and constructing buildingsand for operating and maintaining systems and services. In those days those buildings were conceptualized andbuilt by master builders with high levels of artisan skills. Technological and socio-economic developments inrecent times have led to remarkable increase in demand for more and more sophistication in buildings resultingin ever increasing complexities. These perforce demand high levels of inputs from professionals of differentdisciplines such as architecture, civil engineering, structural engineering, functional and life safety servicesincluding special aspects relating to utilities, landscaping, etc in conceptualization, spatial planning, design andconstruction of buildings of various material and technology streams, with due regard to various services includingoperation, maintenance, repairs and rehabilitation aspects throughout the service life of the building.This Code, besides prescribing the various provisions, also allows freedom of action to adopt appropriate practicesand provides for building planning, designing and construction for absorbing traditional practices as well aslatest developments in knowledge in the various disciplines as relevant to a building including computer aidedandlor 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 variationsfrom region to region, this Code has endeavored 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, proneness to natural disasters, ecologically appropriate practices, use of eco-friendly materials,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’ is being included for the first time. It gives an overalldirection for practical applications of the provisions of different specialized aspects of spatial planning, designingand construction of buildings, creation of services, and proposes an integrated approach for utilizing appropriateknowledge and experience of qualified professionals right from the conceptualization through construction andcompletion stages of a building project and indeed during the entire life cycle. The ‘integrated approach’ shouldnot only take care of functional, aesthetic and safety aspects, but alSOthe operational and maintenance requirements.Also, cost optimization has to be achieved through proper selection of materials, techniques, equipmentinstallations, etc. Further, value engineering and appropriate management techniques should be applied to achievethe aim set forth for the purpose of construction of a building fully meeting the specified and implied needs ofspatial functions, safety and durability aspects, life and health safety, comfort, services, etc in the building.The aim of the ‘integrated approach’ is to get the maximum benefit from the building apd its services in terms ofquality, timely completion and cost-effectiveness. In the team approach which is an essential pre-requisite forintegrated approach, the aim clearly is to maximize the efficiency of the total system through appropriateoptimization of each of its sub-systems. In other words, in the team, the inputs from each of the professionaldisciplines have to be so optimized that the total system’s efficiency becomes the maximum. It may be re-emphasized that maximizing the efficiencies of each sub-system may not necessarily assure the maximization ofthe efficiency of the total system. It need hardly to be stated that specified or implied safety will always getprecedence over functional efficiency and economy. Further, progressive approach such as that relating to theconcept of intelligent buildings would be best taken care of by the ‘integrated approach’ as laid down in this Part.Quality systems approach and certification thereunder covering the various dimensions brought out above maygo a long way in achieving the above goal of real integrated approach.PART O INTEGRATED APPROACH 3

  • 54. National Building Code Sectional Committee, CED 46FOREWORDA need for codifying and unifying administrative provisions in different development control rules and buildingbyelaws had been felt, particularly in regard to the applicability of the Code, desirable qualifications for the enforcingAuthority and the representative of the owner and responsibilities and duties of the Authority and the owner.It is expected that the town and country planning department will co-ordinate the administrative provisions ofthis Part and the same given in the State Town and Country Planning Acts.This Part recommends the setting up of a ‘Board of Appeal’. The ‘Board of Appeal’ gives the owner/architect/engineer an opportunity to defend the schemes which are based on conventional or new methods of design andconstruction or using new materials, which have been otherwise rejected by the Authority.This Part also emphasizes the need for setting up an Arts Commission for metropolitan areas to safeguard existingaesthetics in the event of new schemes proposed for buildings of public importance or buildings coming up in animportant area near historic/monumental buildings. The Commission can assist the civic authorities in reviewingplans for development from the stand point of assuring good taste and regard for often threatened natural beauties.The Commission can serve as a means whereby by the government and public bodies and individuals could getadvice on artistic questions in connection with building schemes.The first version of this Part was brought out in 1970, which was subsequently revised in 1983. As a result ofimplementing 1970 version of this Part in rewriting building byelaws and development control rules of somemunicipal corporations and municipalities, some useful suggestions were emerged. These were incorporated inthe first revision to the extent possible. The significant changes in 1983 version of this Part included the newadministrative provisions related to development control rules, additional information to be fumishedlindicatedin the building plan for multi-storeyed and special buildings and modified provisions regarding submission ofbuilding plans by Government Departments to the Authority.In this second revision, number of modifications have been incorporated based on the experience gained over theyears specially in view of different techno-administrative and techno-legal regime encountered in various situationsfaced. Specially the provisions of this Part have been thoroughly reviewed in the context of the natural calamitiesfaced by the country, such as the devastating eafihquake in Gujarat in the year 2001, and provisions have beenaccordingly modified to further ensure structural adequacy of the buildings. In this context, structural design ofbuildings in accordance with the provisions of the Code and construction and supervision thereof by competentprofessionals to ensure structural safety have been given due importance in this revision. Other significantmodifications incorporated include: a) Modifications in the definitions of certain terms; b) Inclusion of the concept of team of building officials; c) Inclusion of provision of single window approach for permit for all services; d) Inclusion of provisions regarding computerization of approval processes for building permits; e) Inclusion of provision to certify safety of buildings against natural disaster by engineer/structural engineer and owner; 0 Inclusion of provision of two stage permit for high rise residential buildings and special buildings; g) Provisions regarding inspection of completed and occupied building by the Authority from safety point of view have been made comprehensive; h) Inclusion of provision empowering engineers/architects for sanctioning plans of residential buildings up to 500 mz; j) Provisions for architectural control to effectively take care of the urban aesthetics, have been modified; and k) Inclusion of landscape architect and urban designer among the registered professionals for the concerned applicable works.PART 2 ADMINISTRATION 3

  • 75. National Building Code Sectional Committee, CED 46FOREWORDThis Part covers development control rules, including such aspects as sub-division and layout rules, land useclassifications, open spaces, area and height limitations, means of access, and parking spaces; this part alsocovers the general building requirements, such as the requirements of parts of buildings, provision of lifts, etc.It is expected that for proper coordination and enforcement of the development control rules and general buildingrequirements, the departments concerned, namely, the town planning department and the building department,will coordinate the total development and building activity at both organizational and technical levels.Particular attention is invited to Table 3 on floor area ratio (FAR) limitations. It is emphasized that the floor areaof a single storey building is limited in absolute terms by the type of construction and occupancy class. Also, theabsolute floor areas for different types of construction and different occupancies have a definite ratio amongthem. The ratios as recommended in the American Iron and Steel Institute publication 1961 ‘Fire ProtectionThrough Modem Building Codes’ have been generally adopted in this Part and Table 3 has been developed onthis basis. Table 3 is repeated in Part 4 ‘Fire and Life Safety’ also for convenience of reading.Limitation of areas and heights of buildings is achieved in this country by specifying it in terms of floor area ratio(FAR) or floor space index (FSI). The significance of the contribution of different types of construction givingdifferent fire resistances has not been taken cognizance of in specifying FAR for different occupancies, in thepresent development control rules and municipal byelaws of the country. Table 3, therefore, gives the comparativeratios of FAR between types of buildings and occupancy classes and these have been specified mainly from thefire protection aspect of buildings. To arrive at the actual FAR for different buildings coming up in differentareas, the Authority should further modify them, by taking into consideration other aspects like density of anyarea, parking facilities required, the traffic load (road width) and the services available. The heights of buildingsshall also be regulated, keeping in view the local fire fighting facilities.In some state byelaws, the FAR (or FSI) has been expressed in the form of percentage. However, the Committeeresponsible for preparation of this Code is of the opinion that, it being a ratio should be expressed only in theform of a ratio, as done in this Part.It is particularly to be borne in mind by the Authority that the ratios are definitive and it can assess the particularFAR for a type of construction and for an occupancy and establish a new table, but retaining the comparativeratios as given in Table 3.Keeping in view the enormous problems faced by the country with regard to the ever increasing squatter settlements/pavement dwellers in urban areas (cities of all sizes), it is imperative that all the urban local bodies sooner or laterevolve schemes for their rehabilitation. The resources are meagre and the problems are enormous. There hasbeen a tendency on the part of a number of development agenciesflocal bodies to link space norms withaffordability. Affordability is an important criterion but at the same time a public agency cannot ignore the basicminimum needs of the family to be housed (including the mental, physical and social health of the marginalizedgroups, which is linked with shelter). The local bodies shall have to evolve appropria~ policies for their integrationwith the broad urban society and generate/allocate resources and more importantly adopt a planning process,which are people friendly. The Government of India has also formulated the National Slum Policy to this effect.Therefore, keeping in view the needs of low income housing, to cater to Economically Weaker Sections ofSociety (EWS) and Low Income Group (LIG), the requirements on planning, design of layouthhelter havebeen rationalized and the same are provided in this Part. This will contribute significantly in the massivehousing programmed undertaken for the low income sector. This information is based on the provisionsof IS 8888 (Part 1) : 1993 ‘Guide for requirements of low income housing: Part 1 Urban areas (jirst revision)’.Further, city development process would need a dynamic approach to take care of urban renewal and alsodevelopment needs in dense core areas of the cities. Innovative approaches in planning and design with participatingmodels of public private-people’s partnership become necessary to solve the emerging development needs. WithPART 3 DEVELOPMENT CONTROL RULES AND GENERAL BUILDING REQUIREMENTS 3
  • 76. this in view, many city development agencies have evolved innovative planning and development tools liketransferable development rights (TDR) where the developer would receive a portion of the development rights ina new location, keeping in view the constraints in the existing land area and the development potential. Suchdevelopment rights can be transferred into outskirts or new developed areas where land availability is assured.This would encourage the professionals and developers to participate in urban renewal and at the same timeensure that the developments in both the inner core areas and new areas take place in an orderly and efficientmanner. The TDR concept should be increasingly encouraged by the authority dealing with urban renewal, re-development projects including housing and re-development projects for slum including dwellers.Urbanization in India is taking place at a rapid pace. With 5 million population in cities at the time of independence,it has already crossed 28 million (2001 census). It is likely to be 50 million by 2021. The number of cities andtowns have been expanding and there are 5161 cities and towns of various sizes. In the Indian practice citiesover 50 lakhs population have been identified as mega-cities (6 in number) and cities over 10 lakhs (29 innumber) population as metro-cities. These 35 cities above 10 lakhs population is likely to be above 70 by 2021.The other cities are either small or medium towns or cities with different population limits. Urbanization in eachof above cities and towns (mega-cities, metro-cities, small and medium towns and cities) will be different innature and the development challenges are also different keeping in view the extent of urbanization,industrialization, commercialization and the nature of transportation needs. Therefore, the Code provisions shouldbe appropriately utilized depending upon the need of hierarchy of cities for which the administrative and technicalrequirements have been covered in the Code for various facets of the activity.The first version of this Part was prepared in 1970. As a result of incorporation of this Part in the reviseddevelopment control rules and building byelaws of some municipal corporations and municipalities, some usefulsuggestions had emerged. First revision of this part was brought out in. 1983, where these suggestions wereincorporated to the extent possible. The major modifications incorporated in the first revision included: a) Addition of development control rules giving guidance on means of access, community spaces and other aspects required for planning layouts. b) Addition of provisions regarding plot sizes and frontage for different types of buildings, such as detached, semi-detached, row type and special housing schemes. c) Requirements of open spaces for other occupancies, such as educational, institutional, assembly, industrial buildings, etc, were included. d) Provisions relating to interior open space were elaborated, including requirements for ventilation shaft. e) Requirements of open spaces for group housing development were covered. f) Requirements of off-street parking spaces were covered. g) Requirements for greenbelts and landscaping including norms for plantations of shrubs and trees were covered. h) Requirements of certain parts of buildings, such as loft, store room, garage, basement, chimney, parapet, cabin, boundary wall, wells, septic tanks, office-cum-letter box room, meter room were included. j) Special requirements of low income housing were covered.The term Development Control Rules used in this Part encompasses the related aspects comprehensively with aview to promoting orderly development of an area.This second revision is being brought out to incorporate the modifications found necessary in light of the experiencegained with the use of this Part. Significant modifications incorporated in thk revi’sion include: a) Terminology given in this Part has been made exhaustive by incorporating definitions of additional terms used, such as, access, chimney, to erect, etc, and number of terms pertaining to cluster planning for housing. b) Detailed planning norms/open spaces for various amenities such as educational facilities, health care facilities, socio-cultural facilities, distribution services, police, civil defence and home guards, and fire services have been included. c) Off-street parking requirements have now been also included for cities with population (i) between’ 1000000 and 5000000, and (ii) above 5000000 (see Annex B). d) Special requirements for low income housing given in the earlier version have been modified and updated (see Annex C) based on IS 8888 (Part 1) : 1993 ‘Guide for requirements of low income housing:4 NATIONAL BUILDING CODE OF INDIA

In these revised provisions, single room dwelling has been discouraged, guidelines for water seal latrine have also been incorporated, and cluster planning approach has been recommended. e) Requirements for cluster planning for housing have been added (see Annex E), which are based on the guidelines given in IS 13727:1993 ‘Guide for requirements of cluster planning for housing’. f) Special requirements for low income housing for rural habitat planning has been added (see Annex F). g) Special requirements for development planning in hilly areas has been added (see Annex G). h) The requirements for buildings and facilities for the physically challenged have been revised, with listing of additional categories of physically challenged; modifications in requirements of ramps, stairs, doors, handrails and controls; and incorporation of additional requirements regarding windows. j) Also, the opportunity has been utilized to update the reference to Indian Standards.PART 3 DEVELOPMENT CONTROL RULES AND GENERAL BUILDING REQUIREMENTS 5
