Introduction to National Building Code and Steps in a Construction project

1.

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

Introduction:- National building code is a document that provides guidelines for the construction of the structure

• The structure may Residential, Industrial, Commercial, Mercantile etc.,
• All the structures should satisfy this condition if not then project is not approved

Answer:-

• Building code are mainly required to protect public health, safety and general welfare as they are related to construction of building and structures 
• A set of standards that are uniform to all structures :- It gives the information about set of standards which are uniform to all the structures
• It protect the construction safety:- This code protects the overall health of the construction as well as the public and residence construction
• Modern construtcion method:- The designer constantly refers this building codes which enhances their knowledge in this field. It also enables the modern construction methods  with the standard methods
• Provides building standards :- The methods helps in government agencies to approve the plan, It become law of particular juristriction when formally enacted by government authority

6.

Aim:- Distinguish the roles of Design team and Management team

Introduction:-

• Design team is made by the design engineers who is responsible about the structural and architectural models
• The design team includes the design engineers and architectures
• Management team look over the construction and management of the structure
• The design engineers also include in the management team 

Answer:- 

Design team:- 

• Helps to finalise the plan :- The project needs coordination of multidesciplinary professionalists. To design multidesciplinary projects the design engineers are necessary to give the design of structural project to the clients. They should take care about the structural elements
• Evaluationaries in the project:- In this stage the evaluation is done by the design engineer and here the coordination of the client is necessary. This step not work without a client, he will be the backbone for the evalutation
• Implementation the design:- In this stage the design engineer should associate with both the construction and execution time. They follows the NBC guidelines clause 4.1 for the approval 

                               

Management team;- 

• Accomplishment of Project :- They need to achive the accomplishment of project with the coordination of design and specification within the time as well as the cost frame work
• Execute the design:- This team also responsible to day today executions, supervision, quality controal etc., 
• Achieves the satisfactory completion of project :- They are also achieve the satisfactory completion of project along with the cost, controal and quality. Depending on the complexity of the project design team also become management team. They follows the NBC gudeline clause 4.2 for the approval of the project
