Introduction to National Building Code and Steps in a Construction project

QUESTION 1

BUILDING CODES of standard modeling

• A model building code organization is a set of building codes that are developed and maintained by a standard organization. This standard organization operates independently of the jurisdiction or area in which the building code standards are being developed.
• Local Govt or councils can adopt these building codes as they see early, to the better observation of construction within the area
• Building codes organization establish minimum safety, construction, and material requirements for builders to adhere to it
• To achieve the minimum standards of safety and welfare of residents of a building, the governing body defines a set of guidelines to regulate the construction activities termed building codes.
• A building code is a set of rules to regulate the construction activities across the country
• NBC ( National Building Code of India) is a comprehensive building code, is a national instrument providing guidelines for regulating the building constructions activities across the country.
• It serves as a model code for the adoptions by all agencies involved in building constructions work be the Public Work Departments, other Govt construction departments, local bodies, or private construction agencies.
• The code mainly contains administrative regulations, developments control rules and general building requirements, fire safety requirements, stipulations regarding materials, structural design and constructions, building and plumbing services approaches to sustainability an,d asset and facility management

QUESTION 2

From the National Building Code list the groups that will be essential to you when you beibegindelling in Autodesk Revit

For the convenience of the users, this information is also in folthe lowing five groups of the NBC of India 2005 each incorporating the related thets/sections dealing with a para particular area of building activity

GROUP 1: For development, building planning, and related aspects

GROUP 2: For structural Design and Related aspects

GROUP 3: For Construction Related aspects including Safety

GROUP 4: For aspects Relating to Building services

GROUP 5: For aspects relating to plumbing services including Solid Waste Management

OR

GROUP A: Residential

GROUP B: Educational

GROUP C: Institutional

GROUP D: Assembly

GROUP E: Business

GROUP F: Mercantile

GROUP G: Industrial

GROUP H: Storage

GROUP I: Hazardous

Designing should be done in the respective areas

The code, besides prescribing the various provisions also allow freedom of action to adopt appropriate practices and provides for building planning, designing,d construction for absorbing traditional practices as well as latest developments in knowledge in the various disciplines as relevant to a building including CAD or Modern sensor aided activities in the various stage of conceptualization, planning, designing, construction, maintaining and re repairing buildings.

India being a large country with sustainable variations from region to region, this code has endeavored to meet the requirements of different regions of the country, geographical terrain, proneness to natural disaster, ecologically appropriate practices, use of eco-friendly materials, reduction of pollution, protection, and improvement of local environment and also socio-economic consideration toward the creations of sustainable human settlement

QUESTION 3

A land development/ building project comprises the following major stages

• Location/siting
• Conceptualization and planning
• Designing and detailing
• Construction/execution
• Maintenance and repair

Each stage necessarily requires professionally of many disciplines who should work together as well coordinate terrain to achieve the desired product delivery with quantity, in an effective manner

QUESTION 4

An appropriate multi-disciplinary team needs to be constituted to successfully meet the requirements of different stages. Each team may comprise need-based professionals out of the following depending upon the nature, magnitude, and complexity of the project.

• Town planner
• Urban designer
• Landscape architect
• Security system specialist
• Interior designer
• Quantity surveyor
• Project/Construction manager
• Accessibility and universal design specialist
• Asset/Faculty manager
• Other subject specialist

QUESTION 5

QUESTION 6

DESIGN TEAM

Use specialized software to create models and drawings of products

Research new materials and methods of development

Organize and maintain existing engineering records

Construct prototypes and confirm designs with the design/ purchasing team

Perform physical testing on engineering prototypes

Ensure components and assemblies adhere to applicable industry and business standards

MANAGEMENT TEAM

Initiating project managers begin each new project by defining the main objectives of the project, its purpose, and planning.

Once the charter is approved, the project manager works with key stakeholders to create an integrated project executing

During this phase, team members complete the work that has been scheduled
