Creating Architectural and Structural model with 3D rendering using REVIT

1) Aim : To select type of the structure for modelling in the Revit software.

Introduction :

• Depending upon the type of structure the design consideration of building for the modelling purpose vary.
• So it is important to clarify the type of structure before starting any project so that it will serve its functionality for which it is being modelled.

Procedure :

• Type of structure from above three is International school building which is classified as educational building for every 5000 population as per national building code 2016.
• It is G+3 educational building.

Result :

Therefore type of structure is selected as school building for modelling in the Revit.

2) 

Aim : To assume reasonable assumption and location details for the project and identify the modelling requirement from NBC.

Introduction :

• National building code provides the standards which should be followed while designing any type of the model.
• It provides minimum standards which should be provided for different type of structure for different locations so that it serves its functionality optimistically without violating environmental and safety measures.
• Likewise for school building NBC provides the minimum standards for area, height, thickness of wall etc.

Procedure :

Assumptions for geographic and location details and NBC 2016 requirement for project modelling are as follows.

• Assume geographic location for project model is Mumbai India.
• As per National Building Code part 3 page no. 25 minimum land area per school is 0.4 ha.
• Minimum school building area is 0.2 ha.
• Minimum play field area inclusive of the limited parking requirement for functional uses is 0.2 ha.
• As per clause 12.3.1.1 part 3 of NBC Minimum ceiling height for educational building for all region is 3.6 m which is 12’.
• Minimum width provided for staircase for respective occupancies as per Fire and Life Safety code part 4 is 1.5 m for educational building.
• As the total height of building is 40’6” I e 12.3 which is less than 15 m so there is no need to provide the lift.
• In Revit software we can set the location using manage tab, using location tool of the project location panel.
• By clicking it we can set the location for the project as shown below.

Result :

Therefore, location for building is assumed as Mumbai India, and also based on assumption and type of the structure selected modelling requirements of NBC are identified above.

3) Aim : To include the foundation, columns, roof framing, floor, floor opening in structural model in Revit software.

Introduction :
