Creating Architectural and Structural model with 3D rendering using REVIT

1) Select the type of structure you want to build from one of the three below:
a. Multi-Unit Residential Apartment
b. Office Buildings
c. School

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 primary school building which is classified as educational building for every 5000 population as per national building code 2016.
• It is G+1 educational building.

Result :

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

2) Assume reasonable assumptions for geographic and location details for your project modeling. Based on assumptions and type of structure selected identify the modeling requirements from NBC

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) Using the structural model, include the following components based on the type of structure selected
a. Foundation – Isolated / Wall/Matt Foundation
b. Columns
c. Beams Connected to Columns
d. Roof Framing/ Truss
e. Floor / Decks
f. Floor Openings for Elevators and Stairs

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

Introduction :

• The components such as foundation, columns, beams, floors are the structural elements of the model which carry various kinds of loads coming on the structure.
