Introduction to National Building Code and Steps in a Construction project

CHALLENGE WEEK - 5

REVIT

Question no. 1: Why are building codes or standards essential for the modeling/ efficiency of drawings in Revit ?

Answer:

• National Building Code(NBC) is a set of standard guidlines thatplays a very important role in construction of a building.
• This NBC code ensures the health and safety of the building.
• And also it ensures the saftey the user of the buidling.
• These guidlines are set to protect the standardization of the construction of a building.
• These codes are very essential to be refered before planning teh construction of a building.
• These guidlines must be followed so that the building is approved by the authorities who authorizes and maintains the safety of building construction on behalf of the government.
• These guildines are updated to satisfy the modern requirement of the construcction.
• The NBC code maintains the standards followed in all types of the building uniformly.
• Hence the National Building Code(NBC) is essential for the modelling or drawing the building model in Revit.

Question no. 2: From the National Building Code list the groups that will be essential to you when you begin modeling in Autodesk Revit.

Answer:

• The National Building Code is divided as 9 parts to specify the standards in each type of building in their construction.
• Those 9 parts of the National Building Code is listed below.

1. GROUP A : Residential Building.
2. GROUP B : Educational Building.
3. GROUP C : Assembly Buildings.
4. GROUP D : Institutional Buildings.
5. GROUP E : Mercentile Building.
6. GROUP F : Bussiness Buildings.
7. GROUP G : Storage Buildings.
8. GROUP H : Industrial Buildings.
9. GROUP J : Hazardous Buildings.

• Each part contains several set of guidlins and norms to be followed to construct a building to ensure safety and health of the buildings.

Question no. 3: List the five major steps that occur in project cycle . The steps should include from conceptualization of project to maintenance and final stage.

Answer:

• When coming to the project cycle in a construction, There are several steps that takes the construction procedure in a proper schedule and standars.
• Those Steps are:

1. Initiation.
2. Planning
3. Execution.
4. Closure.

• Initiation:

• Initiation is nothing but the steps involved in the beginning of the project.
• Initiation is deciding the procedures of the project.
• In initiation step the contrater takes up a clear conversation and suggestions from the client.
• The authorities or the project manager clears the doubts and problems in the beginning of the project.
• The contractors develop a clear document on the construction and study the documenst provided by the clinet.

• Planning:

• Planning is the next step to initiation.
• In planning the team plans the building procedures.
• After the project being confirmed.
• The building is designed according the site for the building.
• And also the planning involves the deciding of the steps to be followed while construction process.

• Execution:

• Execution is the next step to planning.
• Execution is implementing the plan created.
• Execution is the action on the project.
• Execution invloves setting up the labours to the process and begging of the construction physically as per the plans.

• Closure:

• Closure is the final step of the project of the construction.
• In closure the final checks on the project is taken care of.
• The final budgts closure is taken care.
• The project ends here and taken to the final shipment to the client.

Question no. 4: Give examples of different disciplines involved in construction of a project

Answer:

• There are certain disciplines involved in construction of a project which helps the construction produce a effiient output.
• Those disciplines are:

1. Construction.
2. Finance and estimation.
3. Contracts and bid.
4. Geotechnical.
5. Management.
6. Structural.
7. Surveying.

• Construction:

• The construction is the major part of a project.
• In construction the building is raised, developed and maintained.
• Construction is the process where man power and machineries are used in the site.

• Finance and estimation.

• Finanace & estimation is a segment where the budgeting of the project is taken place.
• Here they decide the budget, cost estimation and all the account matters.

• Contracts and Bids.

• The team to take up the project from the clients ios called as the contractors.
• The contractors deal with the construction of the project.
• The bidding is done to decide to aquire a contractor for the project effieciently.

• Geotechnical :

• Geotechnical is based on the soil on which the site of construction lies.
• The geotechnical process takes care of the strength of soil.
• Load bearing of the soil.]
• Seismic/ earthquake action and preventive measures.
• It is a very important step for the safety of the building.

• Management.

• The management is the peimary thing in the project.
• the management involves the managing of the project through all the process very carefully, efficiently.
• Management deals with taking the project very smoothly.

• Structural :

• The structurral of teh builing deals with the strength of the building.
• Like the structural members to be designed to handle the strength of the building.
• Structural is also a very important factor.
• It also plays a vital role on the strength and safety of the building.

• Surveying:

• Surveying is basic thing to begin or to run the project.
• Surveying involves the overview or the specifying of the positions and much more.
• Survey is important to develop the building in a specific position and to suvery over area and other dimesional parametre.

Question no. 5: 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

Answer:

• Building are classified according to the suitable codal norms of National Building Code.
• According Codal norms for aprticular type of building the code is parted as 9 parts.
• And the building are classiefied accordingly.
• The building typer relating the part of the code is:

• Four Unit Appartment: GROUP A: Residential Buildings.

1. As the appartments are used as residential purpose they are classified into residential Buildings.

• School with capacity of 1000 students: GROUP B : Educational Buildings.
• A Single unit shop: GROUP E : Mercantile Buildings.
• Multi Story Shopping Complex: GROUP E : Mercantile Buildings

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

• The model created has a plot size of 40ft x 30ft Which is 1200sq.ft
• Which is 111 sq.m
• This area is permissible according to the codal norms.

• Room Sizing:

• The room sizing norms ofa building is given in
• NBC 2005, C-3.3

• The rooms created in the model ahs sizings of:
• The room area is added up as 86sq.m which is greater than the said codal provision.

• Wall height:

• The NBC 2005 states the limitations for the wall heights in clause F-3.4,
• The limitations are shown below.

• In the model created by me, The wall heights are of 10ft which is 3m.
• The height in my model is permissible as per NBc provisions.

• Thickness based on fire life and safety:

• The thickness of the wall depends on the usage of the wall to the corresponding rooms.
• The provision given by teh NBC 225 is shown below.

• In my model, I have used 9" for the main walls walls which is 230mm which is permissible.
• And for parttioning walls i have used 4.5" walls which is 115 mm.
• And both thicknees of wall which I have used is permissible by the NBC 2005.

• Passageway requirements:

• The passageway requirement of a standard building is given below.

• In the model i have created the passageway access are under the suggested limitations.

Question no. 8: We have identified requirements for modeling from question 7, Use these numbers from code book and verify the numbers used in modeling the unit from week 2 to week 4. If the numbers are not reasonable, use the numbers obtained from the code book to create a revision of the mode.

This model resembles the actual modeling requirements for Project 1 of course work

Answer:

• The National Building Code(NBC)-2995 was verified with the model.
• All the standard reqiorement for modelling of the building is checked referring the NBC.
• And the model created by me had all the measurements, provision and valure acceptable ny the National Building code 2005.
