A comprehensive national instrument prepared by the Bureau of Indian Standards (BIS) that provides guidelines for regulating building construction activities across India; its first version was published in $1970$ and its latest revision was in $2016$.

Building (NBC Definition)

Any structure constructed of whatever materials and for whatever purpose, whether used for human habitation or not, including foundations, plinths, walls, floors, roofs, plumbing, and building services; temporary tents, shamianahs, and tarpaulin shelters are excluded.

Group F (Mercantile Buildings)

Buildings utilized as shops, stores, departmental stores, or markets for the display and retail or wholesale sale of merchandise, including incidental storage and service facilities.

Group G (Industrial Buildings)

Any building in which products or materials of all kinds and properties are fabricated, assembled, manufactured, or processed.

Group H (Storage Buildings)

Buildings primarily used for the storage or sheltering of goods, wares, merchandise, vehicles, or animals—such as warehouses, cold storage units, freight depots, transit sheds, and grain elevators—characterized by a low occupant-to-area ratio.

Group J (Hazardous Buildings)

Buildings used for the storage, handling, manufacture, or processing of highly combustible, explosive, corrosive, or toxic materials, chemical fumes, or matter subject to spontaneous ignition.

Kerala Building Rules (KBR)

State-level building regulations framed based on the National Building Code (NBC), comprising the Kerala Municipality Building Rules (KMBR) for urban areas and the Kerala Panchayat Building Rules (KPBR) for rural areas.

Coastal Regulation Zone (CRZ)

A regulatory framework that came into effect in $1991$ under the Environment Protection Act, $1986$, to protect India's coastal stretches and ecosystems within $500\,m$ of the High Tide Line (HTL) from unregulated human and industrial activities.

CRZ-I

The coastal regulation zone comprising ecologically sensitive and important areas (such as mangroves, coral reefs, sand dunes, national parks, and marine sanctuaries) as well as the intertidal area between the Low Tide Line (LTL) and the High Tide Line (HTL), where no new construction is permitted.

CRZ-II

Coastal areas that are substantially built up within legally designated urban or municipal limits, where new construction is restricted to the landward side of existing authorized structures or roads and prohibited on the seaward side.

CRZ-III

Coastal zones in rural or undeveloped urban areas that do not belong to CRZ-I or CRZ-II, subdivided into a protected zone near the water and an outer development belt.

No Development Zone (NDZ)

A designated strip extending up to $200\,m$ landward from the High Tide Line (HTL) within CRZ-III where no construction is permitted except repairs of existing authorized structures, agriculture, pastures, and sea-salt manufacture.

CRZ-IV

The coastal zone category covering the water area and seabed from the Low Tide Line (LTL) seaward up to $12\text{ nautical miles}$, as well as tidal-influenced rivers, creeks, and backwaters having a salinity concentration of at least $5\text{ ppt}$ during the driest period of the year.

Hilly Area (Classification Criteria)

Under building norms, any location positioned at an elevation greater than $600\,m$ above mean sea level or exhibiting an average terrain slope of $30^\circ$ or more.

Site Plan

A dimensioned technical drawing prepared to a scale of not less than $1:400$ detailing property boundaries, survey numbers, setbacks, street widths, contours, north direction, and locations of existing and proposed structures.

Economic Infrastructure

The framework of physical facilities and assets that directly support and stimulate national production and economic activities, including roads, railways, airports, power stations, dams, and communication networks.

Social Infrastructure

The foundational facilities that indirectly foster national economic development by cultivating human capital and societal well-being, such as schools, colleges, healthcare centres, public parks, and transit terminals.

Built Environment

The human-made physical surroundings in which individuals carry out day-to-day life, work, and recreation, ranging from individual residences to bridges, educational institutions, and commercial complexes.

5 M’s of Construction Management

The primary operational resources managed and coordinated by construction engineers to turn engineering designs into reality: Men, Material, Machinery, Money, and Management.

Geotechnical Engineering

The discipline of civil engineering that combines soil mechanics and foundation engineering to investigate the behavior, stability, settlement, and bearing capacity of soil and rock beneath structures.

Soil Mechanics

The branch of engineering science that studies the physical, mechanical, and hydraulic properties of soil and its behavior when utilized as an engineering foundation or building material.

Foundation Engineering

The field of civil engineering focused on designing, constructing, maintaining, and renovating substructures that safely transfer loads from the superstructure to the supporting soil or rock strata.

Surveying

The art and science of determining the relative positions of points on, above, or beneath the Earth's surface through direct and indirect measurements of distances, directions, angles, and elevations.

Remote Sensing

The science and technique of collecting information and data about objects or regions from a distance, typically through sensors mounted on aircraft or satellites.

Geographic Information System (GIS)

A specialized computer-based system designed to capture, store, manipulate, analyze, manage, and present all types of spatial, map, or geographical data.

Built-Up Area

The total area covered by a building across all floor levels, explicitly including mezzanine floors, galleries, barsati, and penthouses at the terrace level.

Plinth Area

The covered built-up area of a building measured at the floor level of any storey or basement to an accuracy of $0.01\,m$, excluding open un-enclosed porches, lofts, mumties, and open staircases.

Floor Area

The total area of floor space enclosed between walls—calculated as built-up area minus wall area—consisting of usable rooms, verandahs, corridors, entrance halls, kitchens, and bathrooms, but excluding door and window sills.

Carpet Area

The net usable or liveable area inside an apartment or building where a carpet can be laid, excluding the space occupied by external walls, staircases, toilets, lift wells, escalators, and equipment plant rooms.

Super Built-Up Area

The total saleable area charged to a buyer, calculated as: $\text{Super Built-up Area} = \text{Built-up Area} + \text{Proportionate Common Area}$.

Floor Space Index (FSI)

Also known as the Floor Area Ratio (FAR), the regulatory ratio defined as: $\text{FSI} = \frac{\text{Total Built-up Area}}{\text{Plot Area}}$, which determines the maximum permissible total floor area on a given plot.

Mumty

A small covered structure built over a staircase at the terrace level to protect the stairwell opening from weather elements; its area is excluded from plinth area calculations.

Real Estate Regulatory Authority (RERA)

A statutory oversight authority established under the Real Estate (Regulation and Development) Act, $2016$ (effective May $1$, $2016$) to enhance transparency, enforce builder accountability, and safeguard homebuyer interests across Indian states.

70% Separate Account Rule (RERA)

A RERA compliance mandate requiring developers to deposit $70\%$ of all funds received from allottees for a construction project into a dedicated, separate bank account solely to cover land and construction expenses for that project.

Defect Liability Period (RERA)

A statutory protection clause under RERA making the promoter legally responsible to rectify any structural defects or other specified deficiencies for a duration of $5\text{ years}$ from the date of handing over possession.
