planning and continual updates
of the completed state of the
building.
All of the lacks mentioned above,
and many more others that I did
not count, the BIM educated
investor would avoid. He would
be aware of the BIM workflow
advantages, and he would
actively participate in BIM
workflow and engage BIM
manager, who would work in its
interest.
I am going to process the topic of
"digital twin" in one of the
following articles individually and
explain in detail the optimal way
of creating and handing over a
digital twin to newly designed
objects. I am also going to explain
the need and value of digitizing
existing buildings, all for that
more efficient management of
the building's operating costs and
the cost of the life cycle of the
building mentioned above.
BIM Implementation
From The Contractor
Perspective
Several drawings of elaboration
of one detail cost the cost of
paper and toner for the printer or
plotter, while on the construction
site, every mistake is very costly,
as it often requires additional
work and additional costs when
constructing the building.
With the document „BIM
Execution Plan“ or abbreviated
BEP, BIM educated investor
would formulate BIM
requirements, both for designers
of different disciplines and for the
contractor, who would hand over
the digital models to the investor
after design and construction
phases. These models would
then be handed over or sold by
the BIM educated investor to the
facility manager to manage the
operational maintenance costs of
the facility as efficiently as
possible.
This type of design process and
the construction completion
results in ownership of a digital
model of the completed state of
the building, which can often be
classified as having a "digital
twin" of a building that is under
construction or of the already
constructed building.
When, as a very young engineer, I
started working at a small
contracting firm, the boss often
criticized my laziness. It was
because before undertaking a
specific operation on a
construction site, I did not draw
that detail and elaborate it in CAD
in many ways and more variants.
I have to be honest that at first, I
didn't even realize the need for it.
I remember his definition vividly
that a drawing serves to make
errors several times in suggesting
a solution until the best option is
reached. His conclusion, which I
now completely agree with, was
that a mistake in a drawing is
much cheaper than a mistake in
the construction site itself.
The story, which I started the
section on BIM implementation
from the contractor’s perspective,
was intended to explain, through
a straightforward example, the
meaning of the most ordinary
drawing of details and the
construction of that part of the
construction site.
I hope you noticed in the
introductory section about BIM
implementation from a
contractor perspective that I
indicated that I elaborated on the
detail in CAD and try to imagine
how much savings can be made
by applying a BIM workflow over
a traditional contracting project
made in two dimensions and
paper format.
If we try to make a comparison
between a CAD project drawing
and a fully coordinated
multidisciplinary BIM model, it
