Creating Levels, Grids, Layout and model elements for a residential unit using REVIT

1. Building Information Modelling (BIM)- Building information modeling (BIM) is a process supported by various tools, technologies and contracts involving the generation and management of digital representations of physical and functional characteristics of places. Building information models (BIMs) are computer files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuseand tunnels, electricity, gas, communication utilities, roads, railways, bridges, ports and tun.

In addition to buildings, BIM software is used for designing many types of infrastructure, utilities and systems including:

• Civil and structural engineering
• Energy and utilities
• Highway and road engineering
• Surveying
• Offshore and marine architecture
• Rail and metro transportation engineering
• Tunneling and subway architecture
• Urban master-planning and smart city design

Two things lie at the heart of BIM: (FEATURES OF BIM)- collaboration and sustainability. BIM allows you to bring all your designs, including CAD models, into a single database. Using the cloud, BIM provides access to this database to all project members. You’ll all work on the same models, which allows for quick changes as needed. When used correctly, BIM helps the entire team visualise the project. In fact, this is one of the main benefits of BIM in construction. The team can spot project issues before construction even starts. That’s because of the sustainability aspect of BIM. The methodology allows you to design every aspect of a building. In addition to the building itself, BIM models feature electrical wiring and other important aspects of design. This creates a more realistic digital representation of the final product.

Features of BIM:-

• BIM is a physical representation of the physical and functional characteristics of the building process, that provides every minute detail of the project.
• Every stakeholder makes their discipline-specific input to make it a comprehensive shared information resource about the structure.
• One can easily access the right information at the right time that provides a reliable basis for decision making during a structure’s entire lifecycle.
• BIM models not only present 3D geometric view of the structure, they provide a more comprehensive overview of the entire building process.
• It covers every component of this process from geometrical aspect of the design to spatial relationships,from light analysis to provision of various services,from topographical information to quantities or properties of building components, and so on.
• BIM design tools allow you to obtain various views from a building model and produce high-quality, accurate drawings. These views are based on a single definition of each object and thus gives a more realistic and accurate idea of the final structure.

Advantages of BIM over 2D CAD Tools-

• BIM offers a more complete representation of a building’s design. It takes more than the building’s core components into account. For example, BIM allows you to design electrical and HVAC systems, as well as the building itself.
• This means the project team can take full advantage of the space and resources available.
• BIM pulls your documents into a single database. Several people can work on the same model and save it to the cloud.
• This allows for instant updates, so you won’t waste time searching for documents when you need to make changes.
• A BIM model will allow you to prefabricate important components ahead of time. You won’t have to adjust them based on the building design.
• Instead, such components are part of the initial design. You can provide much more to your clients using BIM than you could with CAD. The models you give to your clients update constantly as you work on your project.
• Your client can check in any time, which leads to quicker approval for milestones and more efficient project development.
• Resource tracking is a key component of BIM models. You’ll be able to figure out how much of each resource you need during the design stage.
• This improves the flow and efficiency of construction.

2. Understand the concept of Categories, Families, Elements, Instances in Revit. Go to Insert Tab, choose a category. Pick a family and element. Understand the instances and insert it to Revit model.

• Category: A Category controls the organization, visibility, graphical representations, and scheduling options of Families within the Project.
• Family: A Family is a grouping of 2D and/or 3D information that serves to represent a discrete building or documentation element in the Project. It defines parametric, graphical, and documentation requirements.
• Instance: An Instance is an individual representation of a Type in the Project defined by unique parametric, graphical, and documentation characteristics which makes it unique from other Instances in the Project.
• Elements: Some elements such as walls, windows, and beams are 3D and appear in all views.
  You can think of these elements as components that exist in a building.
  Other elements such as tags, dimensions, or other annotations appear only in the view in which they are placed.For example we select the family from the door catagory, after selecting the family the new tab will visible Next there will be different sizes of door is there, select any one of them.

LOADING THE FAMILY FROM REVIT 2021-
Open Revit 2021.
Go to the insert tab.
Select the option load families
Select the particular family and enter in Revit.

3. Given that Setting up a Project – Open a project file with architectural template. Save the file with appropriate name. Set up the project units to Imperial / Metric based on your convenience of modelling. Complete the project information under Manage tab. Set up the maximum backups for project file to 3 Setting up a Project – Open a project file with architectural template. Save the file with appropriate name. Set up the project units to Imperial / Metric based on your convenience of modelling. Complete the project information under Manage tab. Set up the maximum backups for project file to 3
Opening the Project with Architectural Template-

Save the project with the name PROJECT_01-

Project Information in the MANAGE TAB

• Go to manage tab.
• Select the option project information.
• Completely fill the information in detail.

Creating backups of the file-
Go to the file menu.
Select save as option and select project.
A save as dialog box will be appearing on the screen.
Click on the OPTIONS TAB in left bottom of the dialog box and set the maximum backups as 3.

4. Understand the concept of Levels and Grids.
Creating different Levels in Revit 2021
Open Revit 2021.
Open Architectural template and select project.
A Revit screen will be opening.
Change the units from MM to Feet and Inches.
Command UN a dialog box will be appearing on the screen,
Change the units to Feet’s.
Now for creation of the different levels go to the view tab on the top bar, select elevation.
From the project browser section in the left o the screen selects the option elevation and select East.
Two basic levels will be displayed on the screen.
Keep the bottom most level and delete the second level.
Rename the bottom level as Ground Floor and rename the height as 0’
Now go to the modify tab and select copy command.
Copy the levels to 10’, 20’, 30’.
Rename the levels as ground floor, first floor, second floor and roof.

Command UN a dialog box will be appearing on the screen,
Change the units to Feet’s.
Go to the Architectural tab and in that select grids option.
Draw the grid in the vertical manner which is already named as 1.
Copy the grid from the modify command and copy the grids at the interval of 20’ spacing.
Draw the grids intersecting the vertical grids in the same manner and name it as A, B, C, D, E.

5. Given that 3D modelling of residential unit – From looking at your house / or a place you aspire. Create a conceptual layout of the residential unit. You can measure using a tape or
you can access your residential plan to create a similar layout.

3D modelling of residential unit –
Open Revit 2021 with architectural template.
Enter UN (Units) command and set the dimensions to feet and inches.
Go to the wall option in the architectural tab.
Draw the external walls.
Again, go to wall option and draw the internal walls by changing the wall settings.

6. In the layout created draft the level of details you are planning to include. Dimensions of room, components you plan to add in the residential unit.
