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.

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.
• Such structural framing elements can be added in the model using the structural template in the Revit software.

Procedure :

Step 1

• Open Revit software, select the structural file linked with the architectural template created last week and open it from home page of Revit software.

Step 2

• Go to structure tab, select the level tool from datum panel, select pick line tool from draw panel and add the levels by specifying offset distance at required position as shown below.

Step 3

• Go to site plan view, select isolated footing from foundation panel of structure tab, select at grids option from place isolated foundation tab and select the grids by dragging the mouse and select finish from multiple

Step 4

• For creating the columns, go to column tool from structure tab, select the column type as concrete rectangular column of size 12 x 18 and change the depth of column as -6’ from properties window.

Step 5

• Go to structure tab, select beam tool, select concrete beam from property window, select on grids option from place beam tab, select the grids by dragging with mouse and select finish from multiple panel.

Step 6

• Select the middle portion of plan, select filter tool from multi-select tab, uncheck grid option and delete key to delete it.
• Similarly delete the foundation from middle portion

• Step 7

  • To hide analytical lines, type VG command, uncheck all analytical model category visibilities from dialog box, select apply and ok

• Step 8
  • Again, select column and create column at ground floor by selecting height option from modify toolbar of column and height up to first floor as shown below.

  Step 9

  • To create the beams and column at the first ang ground floor, go to ground floor plan, select all componenets by draging with the mouse, select filter tool, and select the stuctural column, structural framing from filter dialog box.

4) Using the architectural model, include the following components based on the type of structure selected
a. Wall Layout with appropriate material and finishing
b. Exterior façade with fancy finish
c. Interior partition walls to size rooms
d. Components to add details to a room ( Desk, Chair, Lighting, Plumbing fixtures)
e. Add components such as stairs Elevators
f. Have at-least one side of the building with curtain walls and glass panels
g. Include interior and exterior lighting fixtures
h. Place proper topographic components from outside ( Trees, Parking, Plants) to add details to the model

Aim : To include the architectural components such as walls, exterior façade with fancy finish, partition walls, components adding details to the model, stairs, interior and exterior lighting fixtures, topographical components outside the model in the Revit software.

Introduction

• Architectural elements such as walls, doors, windows etc., can be added in the model using the architectural template.
• Revit is a BIM software where we can add the minor details to make the model more realistic to utilize or make more efficient space management without making any compromises in the future.
• Such details may include desk, chairs, lighting etc.
• In Revit we can also add the topographical features which can be helpful to estimate the excavation or cutting cost even before starting the project.

Procedure :

Step 1

• Open the architectural file from home page of Revit software to add the architectural components.
• Select the walls tool from architecture tab, select wall type generic 12” from property window and draw the walls at required position as shown below.

5) Provide a set of drawings in an architectural and structural model to list the following details with categories and appropriate sheet templates included
a. Floor Plans with Annotations
b. Elevations
c. Sections

Aim : To provide set of drawings in structural and architectural model to list the floor plans with annotations, elevations and sections details in sheet template in Revit software.

Introduction :

• To communicate with the help of drawing with the workers who actually execute the construction of the project on site the annotations such as dimensions are provided and rooms are tagged with their respective names so that it will be executed as per the designed plan.
• Dimensions and room tag add details to the project.
• In Revit dimensions of lines are measured with help of the aligned or horizontal tool of the annotate tab.

Procedure :

Step 1

• Open the architectural template file to give annotation i.e., dimensions to the plan, go to annotation tab, select linear or aligned tool and give dimensions to the plan view as shown below.
• Similarly go to room tool from room and area panel of architecture tab, and give room tags to each room as shown below.

6) Using the Rendering settings, Render images of the 3D model produced and include the rendered images to the drawing sheets
a. Rendering from interior rooms
b. Rendering from out showing topographic features
c. Rendering through structural framing

Aim : To render the images of the 3D model produced and include the rendered images to the drawing sheets by rendering from interior, outside and through structural framing in Revit software.

Introduction

• Revit is BIM software where we can create the 3D views and using the rendering tool of the view tab more realistic views can be obtained.
• In Revit we can add detailed component due to which it is possible to manage or utilize the space even before starting the construction work in the field without making any compromising any pre planed model components positions.

Procedure :

Step 1

• Open the architectural template file.

Step 2

• Go to view tab, select the 3D view tool from create panel and select the camera option and place the camera at the required position to get the 3D camera view.
