Introduction to National Building Code and Steps in a Construction project

1. National building codes and its essential for the modeling/ efficiency of drawings in Revit:

National building codes:

The National Building Code (NBC) is a document that provides guidelines for construction of structures – residential, mercantile, institutional, educational, commercial, assembly, storage spaces or even hazardous buildings.

Essential:

• The National Building Code of India (NBC) is a comprehensive building code, providing guidelines for regulating building construction activities across the country in an uniform manner.
• It serves as a Model Code for adoption by all agencies involved in building construction works.
• It protects the construction safety.
• It covers aspects such as structural stability, fire safety, access, moisture control, durability, services and facilities, and energy efficiency.

2.The list of groups in National Building Code that will be essential to model in Autodesk Revit.

The National Building Code of India, 2016 has the following groups,

• 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 J – Hazardous buildings

3.The list of five major steps that occur in project cycle:

The 5 steps in the project cycle are:

1. Project Initiation
2. Project Planning
3. Project Execution
4. Project Monitoring and Controlling
5. Project Closing

Project Initiation:

• This is where the project’s value and feasibility are measured. 
• It depends on two rules,
• Business case document: Estimate of potential financial benefits are calculated
• Feasibility Study: Evaluation of the project’s goals, timeline and costs to determined are identified here.

Project Planning:

• Project plan gives guidance for obtaining resources, acquiring financing, and procuring required materials.
• The project plan gives the team direction for producing quality outputs, handling risk, creating acceptance, communicating benefits to stakeholders, and managing suppliers.
• The project plan also prepares teams for the obstacles they might encounter over the course of the project.

Project Execution:

• Execution is all about building deliverables that satisfy the customer. 
• Team leaders make this happen by allocating resources and keeping team members focused on their assigned tasks.
• Execution relies heavily on the planning phase. 

Project Monitoring and Controlling:

• Monitoring and control are sometimes combined with execution because they often occur at the same time.
• To guarantee delivery of what was promised, teams must monitor tasks to prevent scope creep, calculate key performance indicators, and track variations from allotted cost and time. 

Project Closing:

• Teams close a project when they deliver the finished project to the customer, communicating completion to stakeholders and releasing resources to other projects. 
• This vital step in the project management life cycle allows the team to evaluate and document the project and move on to the next one, using previous project mistakes and successes to build stronger processes and more successful teams.

4. Different disciplines involved in construction of a project:

The different disciplines involved in construction of a project are,

• Construction
• Finance and Estimating
• Contracts and Bids
• Geotechnical
• Management
• Structural
• Surveying

Construction:

• Managing the building of civil engineering systems from start to end to include coordination between the owner, contractor and designer.

Finance and Estimating:

• Operating in the business world to include accounting, financial contracts and estimating the cost of activities.

Contracts and Bids:

• Demonstrating strong bidding practices and effective contract administration is integral to acquiring the next job or project as a construction manager.

Geotechnical:

• Designing foundations and earthwork systems to support soil itself and transfer loads from structures into the earth while limiting settlements.

Management:

• Managing equipment, personnel and supplies to build more effectively, efficiently and economically.

Structural:

• Designing systems of structural members used to support loads for a specified public function such as bridges, buildings, dams and bell towers.

Surveying:

• Measuring physical features to include horizontal distances and elevation differences to determine property lines, lay out buildings and produce maps.

The other disciplines involved in construction of a project are

• Civil engineers
• Electrical engineers
• Architects
• Interior designers
• Plumbing engineers and so on

5.Buildings classification based on each category:

As per National Building Code of India, 2016,

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

6.Distinguish between Design team and Management team:

Design team	Management team
It mainly focuses on management of project related activities.	It mainly focuses on management of design related activities.
Process of this management includes starting project, planning, executing, monitoring and controlling, and then finally terminating project.	Process of this management includes defining problem, gathering information, set budget, preparing design, monitoring and finally protecting designs.
Its main objective is to identify methods or techniques that one can use and produce a final product on time.	Its main objectives is to plan, develop, and maintain efficient environment of organization by creating well-designed products, services, etc.
Its benefits include improve market position, create new products, reduce time for new products to market, improve customer satisfaction, etc.	Its benefits include increases efficiency, increase sales, increase success, reduce customer complaints, etc.
Factors affecting project management customer needs, time complexity, risk management, cost ratio, capability of process, etc.	Factors affecting design management includes material requirements, functionality, customer requirements, quality of product, etc.

7.The modeling requirements for the project:

As per National building code 2005,

• Height Limitations:

As per National building code 2005,

 

The height the building which I modelled is 7.01m. Hence it follows NBC guidelines.

• Area Limitations:

As per National building code 2005,

The area occupied by my model is greater than 40 sq.m. Floor area of my model is 52’x52’ i.e., 251.2 sq.m.

Hence it follows the NBC guidelines.

• Room sizing:

As per National building code 2005,

 

Above are the size of each room of the model which has size greater than the 9m^2 and minimum width of 2.5m.

Hence it follows the NBC guidelines.

• Wall height:

As per National building code 2005,

In my model the minimum wall height is 3m which is greater than the above value. Hence it is satisfied.

• Thickness based on fire life and safety:

As per National building code 2005,

The thickness of the wall used in my wall is 304.8mm which is greater the minimum value mentioned in the code. Hence it is satisfied.

8) Ques: 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.

Ans: The model is verified with the value of National building code 2005 and it satisfies all the criteria. Hence the building is safe.
