On the other hand, the investor
should be very interested in
getting a digital twin model of the
finished building for reasons that
I will list below.
Unfortunately, it often happens
that the investor does not require
the making of a digital twin
model of the constructed building
at the end of the design process.
Most often, he does not realize its
value and the potential savings in
operating costs and life cycle
costs of the built facility, which it
will bring to the investor, the
owner of the facility, the user of
the building or facility manager.
Also, a common cause for the
absence of a digital twin model of
a built facility is a certain skepticism
with the investor, owner, or
user of the facility or facility
manager.
The most common questions I
hear in discussions about the
need to build digital twin models
in the construction industry are:
• Why do I need a digital twin
model of a building, if I have a
construction stage project?
• Why do I need a digital twin
model of a building, if I have an
as built project?
• What additional value does the
digital twin model give me?
• How to manage the project
process so that the investor will
eventually get a cheap but quality
digital twin model?
• Does it make sense to create a
digital twin model if the building
is already built?
• What to do with a digital model
of a digital twin after making and
purchasing it?
Before giving detailed answers to
each of the questions asked by
the investor, the owner, the user,
or the facility manager, the basic
question is asked - who should
fund the creation of the digital
twin model of the facility? It is not
grateful to go into this dilemma
from this position and to advise
who should finance the digital
twin model, as this may depend
on the contractual obligations
between the investor, the owner,
the user, and the facility manager.
However, I am going to be free to
suggest to the investor that, in
the case of the construction of a
brand new building, if it has a
capable BIM manager who
manages the BIM project process
from the start of the project to
the completion of the construction,
it can have significant
financial benefits if he gets the
digital twin model at the end of
the project. He can accomplish
this by "refining" the BIM model
of the construction stage project,
which he could then hand over or
sell to the owner, user, or facility
manager. On the other hand,
when it comes to creating a
digital twin model of an existing
building, it seems most logical to
me that the costs of making the
digital twin model should be
taken over by the person who
manages the life cycle and pays
for the maintenance costs of the
building and its equipment, which
is usually the owner or user of a
facility.
To simplify the terminology and
relations between the investor,
the owner of the building, the
user of the building and the
facility manager, below, I will look
at the issue of the need to design
a digital twin of the building
through the prism of the user of
the facility, since the user is the
one who will pay the costs of
operating the facility, it’s life cycle
costs and the equipment in it,
and the one should be most
interested in the design and
procurement of a digital twin
model of the facility.
Why Do I Need A
Digital Twin Model
Of A Building, If I
Have A Construction
Stage Project?
By definition, the construction
stage project is a detailed design
of the main design with all the
necessary details defined for the
project to be constructed. The
problem with the construction
stage project is that, in practice,
the built facility is almost always
significantly different from the
