Creating Architectural and Structural model with 3D rendering using REVIT

Creating Architectural and Structural model with 3D rendering using REVIT

Introduction

Revit enables the project to be completed in a combined effort. Structural engineers that are using Revit and are working with architects using Revit Architecture can directly link to the architectural model. Linking a revit architectural file with a revit structure file gives structural engineers a starting point for their design, based on the architects design intend. Changes made by architects can be tracked facilitating design coordination and change management. Similarly, architects using Revit architecture can link revit structure model into their architectural modelsand reap the same coordination benefits.

Architectural model of a building may include walls , doors, windows, stairs etc. contributing to the entire aesthetics of the structure whereas the structural model may include fountation, column, beams, truss works, connections etc. that contributes to the structural stability of the building. These two models can be developed separately and can be linked together to a single model i.e, the construction model.

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

• I have chosen an office building for the project.

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

The office building is planned to be constructed in commercial IT park area in Kochi.

Modelling requirements as per NBC-

Since, my building is an office building, it can be taken as a business building.

• The open space around the building shall not be less than 4.5m.
• Considering the type of construction as type 2 construction , the FAR value for the business building shall be taken as 2.9. The plot size is taken as 40mx70m i.e, 2800`m^2` and individual floor area is 2000`m^2`. Hence, FAR value obtained is 2.14 which is within the prescribed limits as per NBC. `
• The width of the road abutting the building is taken as 9m (30').
• The maximum height of the building shall not exceed 1.5 times the width of road abutting plus the front open space. Building will consist of 3 floors each floor having a floor height of 3.6m. Hence, the entire floor height will be 10.8m, which is within the limits prescribed by NBC.

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 create the following in a structural template:

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

Procedure:

• Initially, open an architectural template and develop a rough plan of the office building as given below.

• Now, draw the grid lines in the architecture template as per the plan developed.

• Now, we have to copy ths grid lines to the structural template.
• For this, first we have to collaborate the project.
• Go to collaborate tab and select collaborate.

• Save the file as a central file.
• Now, open the structural template in the revit software.

• Now, in the structural model ,go to collabrate tab and collaborate.

• Then save the file as central file.
• Now, go to insert option and insert the architecture model link into the structural model.

• Now, in the structural template, go to collaborate tab and choose copy/monitor to copy the grids.

• Choose select link option and then select link in the window and the copy the grids both horizontal and vertical.

• Now, go to Manage tab, and select coordinates in that select specify coordinates at a point.
• Then, choose the horizontal grid an then specify the shared coordinate for north/south as 0.

• Similarly specify the shared coordinates for the vertical grid too.

• Hence, the grids in the structural template is set.

a)

• Now, we have to place the footings and columns in the appropriate positions.
• For this go to structure tab of the revit and in that choose isolated footings.

• Now, place the footings at the required positions.
• The size of the footings is 1800x1200mm.

• These grids are then moved to the foundation level which is at a depth of 2.5m below the ground floor level.

b)

• Now, place the columns above each footings.

• 3D view is given below:

c)

• Next we have to place the grade beam at the ground floor level.
• For this go to structure tab and in that choose beams (concrete beam: 300x600mm).

• 3D view is given below:

• Now we have to complete the framework of the building using this column beam structure.
• For the rest of the beams we have chosen: concrete beam 300x400mm.

• Hence, the entire framework is completed.

d)

• Next we have to provide a roof for the structure.
• Here, I have provided a skylight window at top centre portion.
• The remaining portion will be covered as a flat roof.

• The opening provided at the top is for skylight window. Hence, roof is completed.

e)

• Now, place the structural floor on each level.
• For this, go to structure tab --> floors.
• First draw the floor at ground floor level, then copy it to first, second and third floor.

f)

• Now, we have to provide floor opening for stairs and elevators.
• For this, go to architeture tab --> Shaft opening --> provide opening the at the required position.

• Hence, the opening is also provided.

Result:

All the structural components have been provided in the structural model.

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.

Procedure:

• Initially, we have to link the architectural and structural template.
• For this, first open architectural template and then insert the structural template into it.
• For this, go to insert tab --> revit links --> choose the links.

• Now, using the copy/monitor option we have to copy these elements to structural template.

• Hence, the architectural and structural model that are linked is given below:

a) Wall layout has been developed. Wall thickness provided is 200mm. Now, we have to assign the material to the wall. Here, wall is availbale only in the one third portion rest is provided as curtain wall. Hence, wall material is needed to be assigned only at back portion.

Material provided for the wall is Earth.

b) Exterior facade with fancy finish is also provided.

c) Interior partition walls to size rooms. Wall thickness provided is 138mm .

d) Components are to be added to add details to a room:

• This can be provided by going to architecture tab --> components --> load family --> and then place the required components at the required locations.

• Components have been placed in the ground floor. Similarly components can be place in the first and second floor also.
• This can be done by copying to the level 2 and 3.

• In the third floor, right half is a cafeteria.
• Level1:

• Level 2:

• Level 3:

• Level 4:

• Hence, all the components have been provided successfully.
