Introduction to National Building Code and Steps in a Construction project

Q1

The necessity of the use of building codes while modeling or drafting the plan

• The model building code organization is a set of building codes that is improvised and maintained by the standard organizations
• these organizations follow the jurisdiction of the government council and set the standards that provide the guidelines
• to achieve the safety and welfare of the residents of the building the governing body defines a set of guidelines which are called as building codes
• building codes provide the uniform standards for all the structures based on type of model
• building codes provide a set of rules to regulate the construction activities
• these codes also provide the guidelines in the selection of the construction material
• this code mainly contains administrative regulations, development control rules, general building requirements, fire safety requirements, materials, plumbing, and electrical requirements, structural design, and safety
• these codes are widely adopted by the government offices like the public work department, R and B department, and also other public and private agencies

Q2

LIST OF GROUPS THAT ARE REQUIRED DURING THE DRAFTING FROM THE NATIONAL BUILDING CODES

• 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

Q3

LIST OF FIVE MAJOR STEPS WHICH ARE INCLUDED IN THE PROJECT CYCLE

• initiation

in the initial stage, the management or other authorities will determine the project need and deal with the business and create a revenue

• planning

the planning phase is when project plans are documented, the project requirements are defined, and the project schedule is created. it involves creating a plan to help or guide the team for the progress or completion of the project

• execution

it is the stage in which the project is carried out

• control

in this stage, the execution of the project is monitored to ensure the team the performance of the team and to meet the requirements of the project

• closure

it is the final stage of the project

THE OTHER FIVE MAJOR STAGES OF THE PROJECT ARE

• location/siting
• conceptualization and planning
• designing and planning
• execution/ construction
• maintenance and repair

Q4

EXAMPLES OF DIFFERENT DISCIPLINES INVOLVED IN THE CONSTRUCTION OF THE PROJECT

to meet the requirements of the project at different stages involves different teams based on the stage of the project, nature and complexity involves

• architect
• civil engineer
• structural engineer
• electrical engineer
• plumbing engineer
• fire protection engineer
• HVAC engineer
• environmental specialist
• town planner
• urban designer
• landscape architect
• security system specialist
• interior designer
• quantity surveyor
• project manager

Q5

CLASSIFICATION OF BUILDINGS

building are classified based on the purpose it serves, nature of the occupants, location of the site, and also depends on the plinth area and number of storeys

• 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

four-unit apartment is classified under group A residential

school with a capacity of 1000 students is classified as group B educational

single unit shop is classified as group E business

the multi-story shopping complex is classified as group F mercantile

steel machine factory is classified as group G industrial

Q6

ROLE OF DESIGN TEAM AND MANAGEMENT TEAM

DESIGN TEAM:-

the design team can be a single person who works for the project or the group of people who works for the project involving particularly for each stage of the project

design of the building involves architect, civil engineer, structural design, electrical and plumbing fixtures, fire safety, installation of lifts or exclators, sound insulation, etc so to coordinate the progress of the work or project we need a design team with a professional selected from each discipline of the project

with the coordination of the design team project can be completed in the stipulated time with ease in the progression of the work

the design collaborates right from the initial stage of the project to meet the requirements of the owner

MANAGEMENT TEAM:-

The management team is the group of individuals who operate at higher levels and take up the responsibility of other team members

the main objective of the project manager or the management team is to complete the project as per the design standards and plan within the stipulated time and estimated cost framework

Q7

identifying the modeling requirements of the project w.r.t

HEIGHT RESTRICTIONS:-

• no need to provide a lift for the height of the building up to 15m
• building of LIG should not be more than 2 stories
