Introduction to National Building Code and Steps in a Construction project

1 ANSWER:

1. Some basic set of rules and regulations to ensure the safety and sustainability of the structure should be followed while using REVIT for drawing and design purposes for a model or structure.
2. The main purpose of the building codes is to ensure safety so that the structure does not fail in any condition
3. These set of rules and regulations are the building codes. They are guidelines which are predetermined values for different kinds of buildings .
4. So we have to follow these building codes to get a contract and permission for our building
5. These bulding codes provides safety for the structure and provides building standards

2 ANSWER:

From the National Building Code, list of the groups that will be essential when modeling in Autodesk Revit begun are as follows

• Group A:Residential Buildings
• Group B:Educational Buildings
• Group C:Assembly Buildings
• Group D:Institutional Buildings
• Group E:Mercantile Buildings
• Group F:Business Buildings
• Group G:Storage Buildings
• Group H:Industrial Buildings
• Group I:Hazardous Buildings

3 ANSWER:

The five major steps that occur in project cycle are

1. Project Initiation : This is the first step in project cycle which includes about discussion of about what client needs i.e., selection of site, surveying ,developing design ,cost estimation ,documentation and many more.
2. Project Planning : In next step we start to prepare a basic idea of how to start a project .This step involves preparation of schedule ,labour arrangement ,deployment of engineers etc.
3. Project execution :This step involves executing the plans like deciding the materials required ,excavation,laying foundation
4. Project monitoring : This step is Monitoring the project, solving site problems,checking if everything is going as per schedule
5. Project close : This is the final step which involving finishing the project ,paying attention in checking the quality of the structure,inspecting and handling over the project to client finally

4 ANSWER:

Different disciplines involved in construction project are:

1. Surveying
2. Architects
3. Geotechnical Engineering
4. Contracts and bids
5. Construction Management
6. Structural Engineering
7. Estimation and Costing
8. Construction
9. Commission Authority

5 ANSWER:

Buildings are mainly classified based on their usage like

1. Residential Buildings
2. Educational Buildings
3. Assembly Buildings
4. Institutional Buildings
5. Mercantile Buildings
6. Business Buildings
7. Storage Buildings
8. Industrial Buildings
9. Hazardous Buildings

From given question the following buildings are

1. Four unit apartments -Group A:Residential building
2. School with capacity of 1000 students -Group B:Educational building
3. A single unit shop - Group E: Mercatile building
4. Multi story Shopping complex - Group E: Mercatile building
5. Steel machine factory -Group H: Industrial building

6 ANSWER :

In construction project we require both design and management teams .Both of them plays equal role in construction of project.

DESIGN TEAM:

• Design team has the role of designing the project.
• They are group of architects who co ordinates and plans accordingly to complete the work.
• They are responsible for idea and design.
• They follow rules of NBC Clause4.1 and 4.2
• They gives a 3d view of building which gives complete data of building even before construction.
• They also gives an estimate about budget of the project

MANAGEMENT TEAM:

• The management team has work of managing the clients ,design team etc.
• They will make the design team understand the project.
• They co ordinate between different disciplines and making the project complete in given time with the given resources .
• They plan an important role in executing and carrying the work.
• They ensure safety of work and find different solutions to difficulties at site

7 ANSWER:

From the given question:

a)HEIGHT LIMITATION:

As per NBC 2005,clause C-2.5,the height of the building shall not exceed 15m(page.no.43)

Note that if the buildings up to height of 15m,there is no need to provide lifts

According to building model I had created ,its height is 5.8m i.e.,lessthan 15m.here my model follows NBC guidelines

b)AREA LIMITATION:

As per NBC C-2.3.1,page no.43

According to NBC 2005 ,the minimum plot size with ground coverage not exceeding 75 percentage,shall not be lessthan 40sq.m in small and medium town and not lessthan 30sq.m in metropolitan area.

According to building model I had created,the area occupied by the building model is greater than 40sq.m.i.e.,floor area of my model is 190sq.m

c)ROOM SIZING:

As per NBC 2005,C-3.3,Page no.43

The carpet area of multi purpose single room should be atleast 12.5sq.m

In a house of 2 rooms ,1st room shall not be lessthan 9sq.m with minimum width of 2.5m and second room shall not be lessthan 6.5 sq.m with a minimum width of 2.1m provided the total area of both the rooms is not lessthan 15.5 sq.m

According to building model I had created,number of rooms are 5 and total of rooms is 160.6sq.m,which is greater than the value specified in the code.Hence the building is safe

d)WALL HEIGHT:

According to NBC 2005:Clause F-3.4,the minimum height of rooms and spaces should be:

1)Habitable room-2.75m

2)Kitchen-2.6m

3)Bath/Water closet-2.2m

4)Corridors-2.1m

In case of sloping roof the average height of roofs for habitable rooms shall be 2.75m and the minimum height at eaves shall be 2.1m

According to building model I had created,height of wall is 2.5m which is greater than the minimum wall height specified in the code.Hence it obeys NBC code

e)THICKNESS BASED ON FIRE AND LIFE SAFETY:

The thickness for masonry walls is given by the table 2 of fire and life safety section of NBC 2005 as shown below

According to building model I had created, the wall thickness is 8'' which is greater than the specified value .

f)PASSAGE WAY REQUIREMENTS:

As per NBC 2005,table 1 as shown below

8 ANSWER :

AIM : To verify the numbers used in modeling the unit and to create a revised model

a.Height Limitations
b. Area Limitations
c. Room sizing
d. Wall height
e. Thickness based on fire life and safety
f. Passageway requirements

PROCEDURE:

1. open revit model and annotate all the dimensions and check them whether they are as per NBC or not

RESULT:

a,Hence height of our building was 5.8m which is as per guidelines so that sunlight passes into your building

b.Hence area of bathroom should not be less than 1.8 sqm width should not be less than 1.2 m which is fine in my model

c.Hence room sizes are taken as given in NBC

d.Hence thickness is based on the fire safety

e.Hence passage way requirements are also perfect
