What benefits does BIM provide the contractor?
|
Improved visualization and Collaboration.
|
What is BIM?
|
BIM is a process of collecting, manipulating and analyzing information - not just software or technology.
|
What does the acronym BIM stand for?
|
Building Information Modeling.
|
Is BIM Owner driven.
|
No.
|
What are some common uses of BIM?
|
Spatial CoordinationScheduling Estimating Business Development
|
Who owns the model?
|
Depends on the contract.
|
Can BIM be a 2D representation of the project?
|
Yes.
|
What is important when in charge of the overall model?
|
Regulate models to ensure that they are all in appropriate file formats and are saved with appropriate names, and that (0,0,0) is the same on all models.
|
What is Parametric Modeling?
|
A 3D model based on forms rather than lines; includes more than just the shape but also any important relationships that define the form.
|
Two
Dimensional (2D)
|
Refers to traditional construction drawings on paper
that display a building in multiple views, with each view showing only height
and width, height and depth or width and depth of the space
illustrated in that view. Typical views
include floor plans, elevations, section cuts, reflected ceiling plans and
details.
|
Three
Dimensional (3D)
|
The combination of height, width and depth of the
space illustrated in that view. This is
the basis of building modeling. 3D
creates a more realistic view of a space that can be understood by the
layperson as well as those versed in construction documents.
|
Three
Dimensional (3D) Face Model
|
Looks similar to a solid model, only without
internal information such as volume.
Essentially, a face model is just a shell of the outside. This produces a smaller file size, as inside
information is not included. Wallpaper
is a good example, because its exterior face is extremely thin.
|
Three
Dimensional (3D) Poly Mesh Model
|
Similar to 3D face, except poly mesh tends to be
a single flat plane such as a ground plane.
|
Three
Dimensional (3D) Solid Model
|
Represents the entire volume of an object. Mass properties can also be associated with
solid models to more closely represent real-world objects such as steel or
concrete. If additional information is
needed (mass, volume, bounding box, centroid, moments of inertia, products of
inertia, radii of gyration, principal moments, etc.), they can be extracted
with a click of a button. Solids are the
most informationally complete and least ambiguous of the 3D modeling
types. Complex solid shapes are also
easier to construction and edit than are wireframes and meshes.
|
Four
Dimensional (4D)
|
The integration of time (scheduling) into the 3D
model. This allows for scheduling to be
more easily understood by allowing the equivalent to time-lapse photography
without actually building the structure.
