BIM different from traditional CAD? Provide 2 distinct differences between BIM
and CAD.

How is this interpretation
of BIM different from CAD?


(2 Points) Difference 1:


The traditional Computer Aided Design (CAD) has a lower
degree of relevance compared to the BIM (Wei and Zhang, 2017). In this regard,
relevance is considered to be the point of view of each technology (BIM and
CAD) regarding the building elements. CAD technology views building elements as
comprising of surfaces, lines, and points. A parametric change in the elements
does not reflect the actual elements of the building. On the other hand, the
building elements in BIM includes columns, beams, windows, and walls. Therefore, BIM is more relevant than
CAD since any change in a building elements is effectively reflected in all the
similar building elements in the model.





(2 Points) Difference 2:


The information projected by the BIM is rich and has more content than
that projected by CAD. As such, the BIM can easily communicate and transfer
data to the CNC machines for the accurate
production of the building elements



(4 Points) As discussed in
class, not every BIM use brings value to every type of project. Please answer
the following:

(0 Points, but a plausible
response is required for credit on question) Name one BIM use that may not
always offer value to every project. You should reference the PxP guide for
examples of these.


Digital fabrication (Computer
Integrated Construction Research Program, 2010).




(2 Points) Give an example of
a type of project where the BIM use above may
not offer value and explain why.


Digital fabrication may not offer value in the construction of a simple
ordinary residential building. This is because the building may not require
prefabrication of objects and prototypes. The residential building also rarely
utilize complex forms of architectural expressions.



(2 Points) Give an example
of a type of project where the BIM use above may offer value and explain why.


The digital fabrication use may offer value in complex architectures that
require prototyping and prefabrication. This is because digital fabrication
minimizes the tolerances in designs that require a high level of accuracies, such as those that involve pipe
cutting and structural steel fabrication.




(2 Points) In your own
words describe how the evolution away from the era of the master builder to the
modern age of construction has enabled BIM. Be sure to explain how the
evolution of the industry has shifted responsibilities and expectations for
project participants. Also be sure to explain how BIM specifically supports
this modern approach to design and construction.


In the era of the master builder, the architect had to have
knowledge of versatile fields such as engineering, architecture, and art. The
shift from the master builder to the modern age of construction separated the
disciplines due to the emergence of new and complex designs. The new
disciplines included architects, landscape architects, lighting engineers, MEP
engineers, structural engineers, interior architects, construction managers,
and contractors. The shift has therefore enabled BIM in linking the information
from the different disciplines to create accurate design models. Through
parametric modeling, BIM combines information regarding the cost, material
make-up, the geometry of the structures,
scheduling of the project, the definition
of materials and lightings, and creation of plans, sections, and 3D views for
the contractors, construction managers, and owners.
