BIM Multidisciplinary
Collaboration
I believe that the goal of the
investor is to get a fully coordinated
project at the end of the
BIM project process without
collision between different
disciplines in the project. In
reality, that implies that the
investor is going to get a fully
coordinated multidisciplinary BIM
model at the “as built project”
stage done by the contractor.
This BIM model means the BIM
model of each discipline in the
project process, which is combined
into a multidisciplinary BIM
model and where all BIM discipline
models are fully coordinated
ie. have the status of "zero
clash BIM multidisciplinary
model“.
This kind of makes perfect sense,
given that the building and the
equipment built into it are
completely collision-free, so it is
quite expected that the BIM
model will be a perfect digital
replica, ie. a digital twin of the
building.
I have written three articles on
the topic of digital twins and their
purpose, which detail the
purpose and methodology of
their creation - "What Are The
Digital Twins?", "Digital Twins In
The Construction Industry", "Data
Management In The Digital Twin
Of The Building".
However, it should be borne in
mind that during the BIM project
process, starting from the
conceptual design, at the end of
each project phase (except the as
built project), the BIM multidisciplinary
model does not imply a
multidisciplinary BIM model
without collision between different
disciplines in the project.
The process of moving from
coarse BIM discipline models to a
fully coordinated multidisciplinary
BIM model is achieved by
BIM virtual coordination meetings
(VDRs ), where a visual
review of the BIM discipline
model is performed and a
collision detection test is
performed.
It is expected that as project
phases progress, there is going to
be fewer collisions, but it is
unrealistic to expect a BIM
multidisciplinary model without
collisions between different
disciplines until the as built
project, because many collisions
can be solved on the construction
site, while on the other hand
there is no sense in solving some
of the collisions in the early
stages of the project due to the
investor costs, as long as those
