Introduction to National Building Code and Steps in a Construction project

CHALLENGE WEEK 5

Question: -1

Why are building codes or standards essential for the modeling/ efficiency of drawings in Revit ?

Answer:-

BUILDING CODE: Building code is a set of rules that specify the standards for constructed objects such as buildings and nonbuilding structures

Codes express all aspects of construction including structural integrity, fire resistance, safe exists, lighting, electrical, energy conservation, plumbing, sanitary facilities, ventilation, seismic design and correct use of construction materials.

Building codes classify standard by use and apply different standards to each classification

A building code is a set of rules to regulate the construction activities across the country.

a building code mainly contains administrative regulations development control rules and general building requirements

BUILDING CODES OR STANDARDS ESSENTIAL FOR MODELING OF DRAWING BECAUSE

• The main purpose of building codes are to protect public health, safety and general welfare as they relate to construction and occupancy of buildings and structures
• Model building codes provide protection from tragedy caused by fire, structural collapse and general deterioration
• Codes and standard allow personnel to expand their knowledge base by use of the documents
• Designers use building code standards out of substantial reference books ding design
• The building code becomes law of particular jurisdiction when formally enacted by appropriate government or private authority

as we should follow standard codes of building in software as it gives us the drawing as per the specification in the code book which were ready for construction and can be followed by the vendor.

Question: -3

List the five major steps that occur in project cycle. The steps should include from conceptualization of project to maintenance and final stage.

Ans:-

FIVE MAJOR STEPS THAT OCCUR IN PROJECT CYCLE ARE DEVELOPED BY PROJECT MANAGEMENT INSTITUTE (PI), THE FIVE PHASES OF PROJECT MANAGEMENT INCLUDE

1. Initiation
2. Planning
3. Execution
4. Performance/Monitoring
5. Project close

INITIATION:

• This is the first step in step in the project cycle
• It can also be referred to as the ideation or conceptualization stage
• Formalization of design with clients
• Site investigation and surveying the plot
• Selection of the conceptual design to design in required plot Development of design for the layout
• preparation of primary design
• Estimation of cost is to be estimated
• Preparation of detail BOO

PLANNING:

• This is the second step in the project cycle
• It is a stage where one has to plan the layout of the project one have to estimate the cost of the project
• Preparation of schedules and deadlines
• one has to discuss the teams and individual responsibilities
• labours and materials and all equipment’s to be arranged project workflows.

EXCUETION:

• This is the third stage in the project
• It is a longest and most important stage of our project
• one has to set tasks to team members starting the work
• excavation is to be done and foundations are to be laid according to deadline
• use the resources that were allocated for the project in a effective way Respond quickly to any stumbling blocks
• Keep stake holders updated how the project is progressing

MONITORING

• This is forth stage in the project cycle
• in this stage one has to control the cost, communication between the people
• quality of output and performance
• finding solutions to the problems

PROJECT CLOSE:

• This is the final step in the project cycle
• in his stag we the project manager's checklist for the closure phase of the project would typically look something like this released all deliverables
• tied up any loose ends and made sure that all aspects of the project have been completed
• sending reports to all key stake holders
• TO perform final analysis and to evaluate project is succussed or not

How are buildings classified? Place the following buildings under each category
a. Four-unit apartments
b. School with capacity of 1000 students
c. A single unit shop.
d. Multi story Shopping complex
e. Steel machine factory

Ans:-

The National Building Code of India (NBC), a comprehensive building Code, is a national instrument providing guidelines for regulating the building construction activities across the country. It serves as a Model Code for adoption by all agencies involved in building construction works be they Public Works Departments, other government construction departments, local bodies or private construction agencies. The Code mainly contains administrative regulations, development control rules and general building requirements; fire safety requirements; stipulations regarding materials, structural design and construction (including safety); building and plumbing services; approach to sustainability; and asset and facility management.

• Group A Residential
• Group B Educational
• Group C Institutional
• Group D Assembly
• Group E Business
• Group F Mercantile (relating to trade or commerce; commercia)
• Group G Industrial
• Group H Storage
• Group J Hazardous

1. A) four unit’s apartment comes under group A Residential
2. B) school with capacity of 1000 students comes under Group B education
3. C) A single unit shop comes under Group E Business
4. D) Multi story shopping complex comes under Group F mercantile or Group G Industrial
5. E) steel machine factory comes under Group G Industrial, Group H Storage, Group J Hazardous

Question: -6

Distinguish the roles of Design team and Management team

Ans: -

DESIGN TEAM:

A design team can be a singular individual working on design projects across an organization, up to a team of 50+ designers who have their own department. There's a lot that goes into effectively leading a design team.

In building projects various aspects like form; space planning; aesthetics; fire and life safety; structural adequacy; plumbing services; lighting and natural ventilation; electrical and allied installations; air conditioning, heating and mechanical ventilation; acoustics, sound insulation and noise control; installation of lifts and escalators; building automation; data and voice communication; other utility services installations; landscape planning and design; urban planning; etc need to be kept in view right at the concept stage. The project requiring such multidisciplinary inputs need a coordinated approach among the professionals for proper integration of various design inputs. For this, and to take care of the complexities of multidisciplinary requirements, a design team of professionals from required disciplines shall be constituted at the appropriate stage. Here, it is desirable that the multi-disciplinary integration is initiated right from the concept stage. The team shall finalize the plan. The composition of the team shall depend on the nature and magnitude of the project. Design is an evolutionary and participatory process, where participation of owner constitutes a very important input at all stages, and the same shall be ensured by the design team. (SP 7 GROUP 1 (2005) NCB -4%. DESIGN TEAM)

MANAGEMENT TEAM:

The management team is the group of individuals that operate at the higher levels of an organization and have day-to-day responsibility for managing other individuals and maintaining responsibility for key business functions.

The objective of project management or construction management is primarily to achieve accomplishment of project in accordance with the designs and specifications in a stipulated time and cost framework, with a degree of assurance prior to commencement and satisfaction on accomplishment.

Refer to NBC, Identify the modeling requirements for the project (from week 4).
a. Height Limitations
b. Area Limitations
c. Room sizing
d. Wall height
e. Thickness based on fire life and safety
f. Passageway requirements

Ans:-

1. height limitations

A-2 HEIGHT RESTRICTION

No building or structure higher than the height specified in Tables 5 and 6 shall be constructed or erected, or no tree which is likely to grow or ordinarily grows higher than the height specified in the Tables 5 and 6, shall be planted, on any land within a radius of 20 km from ARP of the aerodromes listed

C-2.5 Height of Building (FORM NBC)

The height of building shall not exceed 15 m.

NOTES

1. 1 For buildings up to the height of 15 m, there is no need to provide lifts.
2. 2 Housing for the low-income group shall preferably be up to
3. a maximum of two stores.
4. 3 Buildings for housing beyond 15 m in height should be

resorted to in exceptional circumstances and it should be

governed by provisions laid down in this Code.

According to my model the height is 7 m. Therefore, it does not extend 15m, so my project is according to NBC standards in height limitations

b.area limitations :(FORMNCB.).

The minimum plot size with ground coverage not exceeding 75 percent, shall not be less than 40 m2 in small and medium town and not less than 30 m2 in metropolitan cities. Plot sizes below 30 m2 but not less than 15 m2 may be permitted in case of cluster planning.

According to my model the area is not less than 40 m^2,my plot size is 41 feet x 37 feet

1. Room sizing

Every dwelling unit to be provided should have at least two habitable rooms. Even if one room house is provided initially it should be capable of adding a new second room in future. However, in case single room tenements are required to be provided where future additions are not possible, the carpet area of multipurpose single room should be at least 12.5 m2. Such one room dwelling units with 12.5 m2 carpet area of habitable space is permitted only in case of on site rehabilitation of slum dwellers. In a house of two rooms, first room shall not be less than 9.0 m2 with minimum width of 2.5 m and second room shall not be less than 6.5 m2 with a minimum width of 2.1 m provided the total area of both the rooms is not less than 15.5 m2.in incremental housing the bigger room shall always be the first room.

According to my model the room sizing are according to NCB
