HOSPITAL PROJECT CHALLENGES
The complex architectural
design, the particularity of
health care buildings, the
time limitation
and the continuous site
changes, are one of the
numerous constraints and
challenges in every
Hospital Project, that BIM
has to overcome in order
to succeed.

Building necessitates
creation and manage of
complex data enriched
elements

11. 1. The parametric polygon model of the Curtain Walls is
created as a basis for replacement with different kinds
of parametric curtain wall panels.
2. A node (generative component) of a curtain wall panel is
created to be the base module for all the different panels that
can be used in the Façade.
CHALLENGE– BIM PROPOSED ACTION
Generative Components – Parametric Elements – Case Study Curtain Wall

12. Due to the generation of the nodes by
Generative Components, they have all BIM

• Laser scanners can be considered as a highly automated total station.
• For each acquired point, a distance is measured on a known direction: X, Y and Z coordinates of a point can
be computed for each recorded distance-direction.
• Laser scanners allow millions of points to be recorded in a few minutes.
LASER SCAN WORKFLOW

15. BIM PROPOSED ACTION IN TIME LIMITATION Indoor Mobile Mapping Solution - Advantages
• It is faster compared with the static
• The point cloud is divided in loops and not in
small zones
• It provides 360° photos
• Mobile point cloud is lighter and can be easily
modified and used as reference in the BIM
environment
• Point cloud is in RGB color and scanned
element’s identity is apparent

INDOOR MOBILE MAPPING SOLUTION

16. Indoor Mobile Mapping Solution
• The IMMS is the optimal fusion of
technologies for capturing spatial data
of indoor and other GNSS-denied
areas of all sizes and locations
• It produces geo-located maps and 3D
PCD data. During scanning a camera
captures 360° images that are
localized in the point cloud
• The scanner moves through a
specified path capturing the max of
info. The raw data process is divided
into internal georeferencing calculation
and the global georeferencing of the
data.

18. CHALLENGE
Non Coordinated-Clashing Disciplines
Disciplines are not coordinated,
resulting in clashes among disciplines.
Changes on Site are usually being
applied in daily basis
BIM PROPOSED ACTION
- Establishment of PCD
Comparison Hierarchy and
Methodology
- Track of Site Changes by
Internal Memos
- Clash Detection
- Site Visits
BIM – POINT CLOUD COMPARISON

19. DISCREPANCIES RESOLVE
The point cloud comparison is a challenging procedure. By
our experience we established a methodology that is based in
3 main factors:
In order to isolate small areas of the model we create a
mask by the use of solid.
By the use of solid and mask we can check the partial area
in plan view and in section

20. Point Cloud Comparison Hierarchy:
A. Division by Discipline and Sub-Discipline
B. Division by Spatial Position:
- Plan View Comparison
- Reflected Ceiling Comparison
- Vertical Elements Comparison
DISCREPANCIES RESOLVE
During comparison between BIM and Point Cloud there are discrepancies
regarding the size, the position, the type and the existence of an element.
These discrepancies are subsequently resolved.

21. 360º PANORAMA - 2D REFERENCE IMAGE IMPORT
- The mobile laser scanner
captures a photo every 1m that it
scans.
- The result is a big amount of
photos that they can not be
related to each exact placement
they are captured.
- In order to do so, the scanner
photos are imported by the
trajectory file as XYZ coordinates
and are placed as text in a
2D drawing that is used as
reference file.
With the LadyBug application,
360° photos can be seen,
in Panoramic, Spherical 3D
and Dome Projection View.
Each photo can be accessed
by typing the Photo Number or see
all photos in raw mode as a video.

24. 2D Drawing Export
From the As-Built BIM, 2D
drawings are exported as lines
in order to be used as
supportive base drawings for
the Engineering Department.
1. Macro for linear forms:
The form’s part name is created
as text in position that follows
the direction line.
2. Macro for free forms-cells:
The form part name is created
as text in position of the forms
center.

25. AS-BUILT BIM – MTO – TAG REPORT – LINKED MTO REPORT
The AS-BUILT BIM has all info
of the current status of the
Building. It is the Building Data
Base for all disciplines.
It can be used for the
extraction of info for any further
work, change, maintenance of
asset purpose
.
The BIM Tag process follows the
Point Cloud comparison and the
Clash Detection

26. AS-BUILT BIM – MTO – TAG REPORT – LINKED MTO REPORT
• Use of 2 macros
1. Macro per room:
Used for all disciplines that
need to contain the Room
number in the Membermark
(ie. Architectural finishes –
MEPF outlets adjusted in Walls
and Ceilings)
2. Macro per zone:
Used for all disciplines that are
identified per zone
(p.e. Architectural Partitions –
MEPF Ducts and Piping
Network)

28. AS-BUILT BIM O&M Case Study
• For the O&M case study, an in
house visual reporting tool is
used.
• Data is segregated into the
project’s Work Breakdown
Structure Levels.
• BIM is loaded per building,
floor, trade, sub-trade,
department, room.
• The object’s categorization is
based on the Trade / Sub-
Trade Template
• Under each Sub-Trade all the
available elements are listed
• By selecting an element all the
available data of the
corresponding Template are
displayed
• The element’s related
documents are listed and can
be displayed
• An element can be linked to
multiple documents

29. AS-BUILT BIM O&M Case Study
• Navigating through the WBS
any related element can be
selected and highlighted
• The selected element’s data
can be viewed by an Ibox
• Elements such as access
panels can be identified and
correlated to the elements
serviced through them

30. • The elements are linked with
maintenance reports
• The element’s related
maintenance operations are
displayed, including data like
Last Maintenance, Operation
Description, Required Tools,
Task Duration, next
maintenance date etc.
• The elements can be subject to
multiple maintenance
operations
AS-BUILT BIM O&M Case Study

31. BEYOND DELIVERABLES
• Through the BIM implementation process, a rich database of relevant information will be created
through the phases of design.
• This database will make future decision processes for the Facility Managers more efficient and
effective.
• Identified information and specified attributes, will be used in the future by the client’s FM team for the
maintenance of information in their database.
• The end goal is to develop a visual framework for the collection of information, which can be stored in an
interactive data management system.
