would be easiest to make such a
comparison by racing motors
through dense forest and racing
along a well-maintained Formula
1 race track, where motor racing
along track with Formula 1 race
track quality is, of course, the
construction of a building using
the BIM workflow.
Here are just a few of the key
benefits that the BIM workflow
provides, without going into a
detailed explanation of each
item, which I am going to do in
one of the following articles:
• 4D – digital simulation of the
construction and simulation of
the construction phases;
• 5D - digital simulation of
building construction, which also
takes into account the cost of
each element in the building. It
allows us not only the making of
the bill of quantities before the
start of construction works but
also an expense summary at any
time during the construction. If
the contractor has more than one
active construction site, in simple
terms, it allows the 5D contractor
to manage the money and supply
of materials in a simulated digital
process of building multiple
facilities, which would
significantly benefit the
contractor during the
construction of the facilities;
• 6D - facility life cycle cost
calculation or facility
maintenance cost management.
By itself, developing a 6D model
is not necessarily the obligation
of the contractor.
Still, it largely depends on the
desire of the investor to whom
they would entrust the creation
of the 6D model.
I must mention that all of the
benefits mentioned above of
implementing a BIM workflow
when building a facility cannot be
implemented without a
previously fully coordinated
multidisciplinary BIM model.
This leads to the logical
conclusion that there should be
an arranged relationship and
trust between the designer and
the contractor in the data they
both generate during the design
process.
Based on professional
experience, I can say that in
many cases, the role of defining
BIM requirements and managing
the generated BIM data between
the designer and the contractor
is taken over by the investor.
The logical reason is that he
finances the design of the project
and the construction of the
building, and therefore an
arranged and efficient data
management during the design
process brings significant savings
to the investor.
In the case where the investor is
also the end-user of the
constructed facility, the arranged
and efficient management of all
the generated data by the
designer and contractor seems
to be the only logical solution
that brings significant savings to
the investor, and in this case to
the owner of the facility during
the design process, construction
process and in managing the
operational cost of maintaining
the facility.
Having defined, and thus
rounded up, data management
and relationships between the
designer, contractor, and
investor in the domain of the BIM
workflow and advanced BIM data
management, I would like to
finish this first article and
announce more of them in which
I am going to go deeper and in
more detail in the topics I started
with this one. In the following
articles, I am going to cover the
topic of "BIM Project Process
Automation".
There, I am going to discuss
efficient data generation
workflows, the role of Dynamo /
