reflects a perfect, as built copy of
the constructed building and the
equipment built into it (digital
twin model);
• A digital twin model containing
parameters valuable for
monitoring the life cycle of a
building and the equipment built
into it;
• Permanent maintenance of the
geometry and parameters of the
digital twin model after each
intervention on the building and
the equipment built into it;
• Generation and labeling of
elements QR codes in a building
or part of equipment over which
an intervention is performed and
labeling with an identical QR code
of an identical element in a digital
twin model to coordinate
real-world building data and its
digital twin model in the digital
world.
The Building’s Digital
Twin Creating and
Maintenance
Contract and BIM
Execution Plan
The primary role of the building’s
digital twin creating and
maintenance contract is to clearly
define the rights and obligations
of the building user on the one
hand and the company that will
be engaged in the creation and
maintenance of the digital twin
on the other. It turned out very
useful to include in the creating
and maintenance contract a
company that will provide
maintenance services for the
constructed facility and the
equipment built into it, i.e., facility
manager. This greatly minimizes
the possibility of communication
problems on the relation building
user - facility manager -
maintaining the digital twin of the
building.
Namely, in contracts that clearly
define the rights and obligations
between the interested legal
entities engaged in the
maintenance of the existing
building, it is crucial to define
clearly and unambiguously the
procedures from the appearance
of the need for intervention on
the building to noting it in the
digital twin model, i.e., to update
it.
BIM Execution Plan, in addition to
the building’s digital twin creating
and maintenance contract,
represents a document which has
the power of the contract and it is
written in the form of contract
addition where it is defined:
• Methodology for creating
building digital twin model;
• Level of Detail (LOD) i.e., the
level of detail of the geometry of
each type of graphic element
within the digital twin model;
• Elements of the building and
equipment that will be subject to
processing in the digital building
twin model database;
• The parameters in the digital
twin model that will be assigned
to the graphic elements of the
model to track them in terms of
maintenance costs and the life
cycle of the facility and the
equipment built into it;
• The manner of issuing orders
and labeling for intervention on
the constructed facility;
• A way to update the digital twin
and the data itself in the building
database after the intervention;
• Documenting all changes made
to the building and the
equipment built into it in the
digital twin model, not only by
changing the geometry of the
digital twin model, but also
establishing a link between the
element in the digital twin model
that was the subject of the
intervention and the
attachments, invoice scans,
textual description of the work
and how to make changes, as
well as other relevant
documentation related to that
element in the digital twin model.
In the end, it is essential to note
in the contract that it is desirable
