General Principles
A BIM mo
odel should not be thou
ught of as a single file containing
c
aall the proje
ect data.
Instead, maximum
m
us
se should b
be made of Bentley’s re
eferencing ccapabilities to
enable co
ollaborative working in a BIM envirronment, inc
cluding worrking practic
ces and
team man
nagement as well as th
he technolog
gical solutio
ons coveredd by the rem
mit of
this docum
ment.
This section deals wiith the princciples of sub
bdividing a model for thhe purposes
s of:
• multi-user access
s,
• opera
ational efficie
ency on larg
ge projects,
• inter-d
disciplinary collaboratio
on.
The follow
wing practices shall be followed:
• No mo
ore than on
ne floor or fa
açade shall be modelle
ed in a singlle Design file.
• A mod
del file shall contain da
ata from one
e discipline / project staakeholder only
o
(altho
ough excepttions may a pply for Buiilding Servic
ces where m
multiple disciplines
conve
erge).
• Drawiing Models will be publlished to se
eparate files
s and shouldd not be sto
ored as
multip
ple models within
w
a sing
gle containe
er file. No more
m
than oone Drawing
g Model
will be
e stored in each
e
file. Th
his is to maximise the effectivenes
e
ss of Bentle
ey’s
refere
encing capa
abilities and to allow mu
ulti-user acc
cess to all aaspects of the
projecct.
• Sheett Models will be create d as separa
ate files and
d should noot be stored as
multip
ple models within
w
a sing
gle containe
er file. No more
m
than oone Sheet Model
M
will be
e stored in each
e
file to allow for da
ata tracking and drawinng managem
ment.
• In ord
der to avoid duplication
n or co-ordin
nation errors
s, clear defiinition of the
e data
ownership throug
ghout the liffe of the pro
oject shall be defined aand docume
ented.
Eleme
ent ownersh
hip may tran
nsfer during
g the projec
ct time-line – this shall be
expliccitly identifie
ed in the Pro
oject BIM Execution
E
Plan.
• Where
e multiple models
m
makke up a sing
gle project, a container model should be
consid
dered, whos
se function is to link the various assemblies ttogether forr
coordination/clas
sh detection
n purposes.
The BIM
B will be made
m
up of a series of 3D Design
n Files (1).
The re
elevant files
s are refere nced into a single “Container” filee (2). This is
s the
locatio
on from whe
ere the Dyn
namic View
ws (3) are created. Whiile it is poss
sible to
create
e Dynamic Views
V
direcctly in the 3D
D Design Fiile, from othher Saved Views
V
or
even from a Sheet Model, u
using a Conttainer file allows you too manage th
he
Viewss more easily (you do n
not need to keep jumping betweenn references) and it

When
n the Dynam
mic Views a re created, a Drawing Model file (4) is also. You
could create thes
se within the
e Containerr file, but as
s these mayy need to be
e edited,
or issued to external consulttants, it is better
b
to kee
ep them as separate files.
The Drawing
D
Models are the
en referenced into the Design Moddel of a She
eet File
(5). This is neces
ssary to pro
ovide DWG compatibilitty. As it is uunlikely that any
projecct contains only
o
3D datta, 2D Model data (7) can
c also bee referenced
d into
here if necessary
y.
The Design
D
Model is re-refe
erenced into
o the Sheet Model of thhe same Sh
heet
File, producing
p
“P

When starting any BIIM project, iit is critical that

A

If the proje

may be notic

to a very small
s
degre
ee that meassurement is
