2. Building Information Modelling
What is BIM?
- BIM is not just software but a methodology of practice.
- BIM means all project data is stored in one location a building information model is the ultimate compilation of construction and design information, housed in a database and graphically represented

Dr. Walid Al-Awad

3. Building Information Modelling
BIM as a promise to offer a high quality project as well as time and cost savings. The ability to visualize the facility as a 3D model helps owners to gain a better understanding, early in the design process of the look of their final project.
Software for BIM .. Revit, Tekla, ArchiCad…….

5. Structure, Member, Element
Structure can considered as an assemblage of “Physical Components” called Members
Slabs, Beams, Columns, Footings, etc.
Physical Members can be modeled by using one or more “Conceptual Components” called Elements
1D elements, 2D element, 3D elements
Frame element, plate element, shell element, solid element, etc.

Dr. Walid Al-Awad

6. Structure, Member, Element
The vertical Load
The structural system (beams, slab, girders, columns, etc) that act primarily to support the gravity or vertical loads
The Lateral Load
The structural system (columns, shear walls, bracing, etc) that primarily acts to resist the lateral loads

7. Create Structural Model
Need for Modeling
Create Structural Model
Real Structure cannot be Analyzed: It can only be "Load Tested” to determine response (S. Fig 1)
We can only analyze a “Model” of the Structure
We therefore need tools to Model the Structureand to Analyze the Model

9. Revit Structure 2015 (BIM)
Revit is a design and documentation platform that supports the design, drawings, and schedules required for building information modeling (BIM). In the Revit model, every drawing sheet, 2D and 3D view, and schedule is a presentation of information from the same underlying building model database.
The Revit parametric change engine automatically coordinates changes made anywhere—in model views, drawing sheets, schedules, sections, and plans.
October-2014
Dr. Walid Al-Awad

10. Building Information Modeling
Parametric modeling refers to the relationships among all elements in a project that enable the coordination and change management that Revit provides. These relationships are created either automatically by the software or by you as you work.
Revit uses 3 types of elements in projects: model elements, datum elements, and view-specific elements. Model elements represent the actual 3D geometry of the building. They display in relevant views of the model.
October-2014
Dr. Walid Al-Awad

11. Building Information Modeling
Model elements represent the actual 3D geometry of the building. They display in relevant views of the model.
Examples: Structural walls, slabs, and ramp
Datum elements help to define project context. For example, levels and reference planes are datum elements.
View-specific elements display only in the views in which they are placed. They help to describe or document the model. For example, dimensions are view-specific elements.

Dr. Walid Al-Awad

13. Building Information Modeling
Each element you place in a drawing is an instance of a family type. Elements have 2 sets of properties that control their appearance and behavior: type properties and instance properties. For Example: cross-sectional dimensions of a beam are type properties, if you select a beam, and change one of its instance property values on the Properties palette, only that beam is affected.

15. Revit Structure 2015
Project: In Revit, the project is the single database of information for your design—the building information model. The project file contains all information for the building design, from geometry to construction data. This information includes components used to design the model, views of the project, and drawings of the design. (plan views, elevation views, section views, schedules, and so forth)
October-2014
Dr. Walid Al-Awad

16. Revit Structure 2015
Level : Levels are infinite horizontal planes that act as a reference for level-hosted elements, such as roofs, floors, and ceilings. Most often, you use levels to define a vertical height or story within a building. You create a level for each known story or other needed reference of the building; for example, first floor, top of wall, or bottom of foundation. To place levels, you must be in a section or elevation view.

35. Revit Families
Revit Families: A family is a group of elements with a common set of properties, called parameters, and a related graphical representation.
Use the Family Editor to modify existing elements or create new ones to meet the specific needs of a project.
All of the elements that you add to your Revit projects are created with families.
October-2014
Dr. Walid Al-Awad

36. Revit Families System Families:
System families contain family types that you use to create basic building elements such as :
walls,
floors,
ceilings,
and stairs in your building models.
October-2014
Dr. Walid Al-Awad

37. Assemblies Revit elements
The Assemblies category of Revit elements supports construction workflows by letting you identify, classify, quantify, and document unique element combinations in the model.
You can combine any number of model elements to create an assembly, which can then be edited, tagged, scheduled, and filtered.
October-2014
Dr. Walid Al-Awad

38. Assemblies Revit elements
Which elements can be included in assemblies?
Most model elements (walls, floors, roofs, family instances, parts, and so on) can be included in assemblies. The following elements cannot be included:
Annotations and detail items
Assemblies and elements that are already part of another assembly
October-2014
Dr. Walid Al-Awad

39. Assemblies Revit elements
Complex structures (trusses, beam systems, curtain systems, curtain walls, stacked walls)
Elements in different design options
You can create assembly views and assembly sheets for an assembly type. These drawings are always associated with a particular instance of the type, and only one instance of a type can have assembly views.
October-2014
Dr. Walid Al-Awad

40. Assemblies Revit elements
Combine multiple building elements into a single assembly
October-2014
Dr. Walid Al-Awad

41. Design Options Design Options:
Use design options to explore alternative designs in the building model. You can develop multiple options for different parts of the model, all within the same project.
For example, you can use design options to consider different roof styles and different front entries in the same building model.
October-2014
Dr. Walid Al-Awad

42. Design Options Workflow: Design Options :
Use this process to develop sets of design options for your building model. In general, the process of using design options is as follows:
Decide on the areas for which you want to develop design options.
Create the building model, including all elements that will be common to all of the design options. (This is the main model.)
October-2014
Dr. Walid Al-Awad

43. Design Options Create secondary options for each design option set.
Create views that display each design option.
Incorporate a design option into the main model.
A design option set is a collection of possible solutions for a particular design problem. Each design option set contains one primary option and one or more secondary options.
October-2014
Dr. Walid Al-Awad
