Capstone Report:
The integration of BIM in Construction
Organizations & it’s impacts on Productivity
April 21, 2016
2. Intensions & Assumptions
To explain the concept of BIM and its impacts on productivity in
the Construction Industry.
To help educate the reader in understanding what BIM is and
how BIM can be implemented in the workforce.
Due to conflicting schedules, only 3 in-person interviews could
be used as primary sources of information
3. Introduction
The Construction Industry accounts for 6% of Canada's GDP
(Statistics Canada, 2016).
Currently, programs like AutoCAD is the popular choice to use
when designing and documenting architectural & construction
drawings
However the process can be slow and most of the time is used
up in coordination and correcting discrepancies.
Which is why increase the productivity and output of
construction drawings and documents is a crucial part in a
project orientated industry such as the Construction Industry.
4. Thesis Statement
“BIM programs & practices are not only used
to help with communication and visual
understandings of a project, but also have a
great impact on accelerating productivity and
achieving a higher project turnover rate.
5. BIM – Definition
In 2016, The Us National
Building Information Modeling
Standard Project Committee
defines BIM as:
“(BIM) . . . is a digital
representation of
physical & functional
characteristics of a
facility. (BIM) . . . is a
shared knowledge of
resources for information
about a facility forming a
reliable basis for
decisions during its life-
7. BIM – History
Charles M. Eastman. Is a pioneer in AEC
CAD and developed early research on
BIM.
In the mid-1970s, he focused on the
development for practitioners with the
‘Building Description System’ and
‘Building Product Modeling’ (which was
later renamed into ‘Building Information
Modeling’ – BIM).
Author of BIM Handbook: A Guide to
Building Information Modeling for Owners,

8. BIM – Off-Site Applications
BIM is mainly used in offices of Construction & Design
companies.
There are 5 main purposes when working with BIM:
Gather – Collect & organize Information
Generate – Create & design with the information gathered
Analyze – Review the design and it properties
Communicate – Present & document the design & information
Realize – Follow through with the design & implement it in the
construction phase
9. BIM – On-Site Applications
BIM can be used to facilitate a virtual walkthrough while on a
construction site – through the use of BIM “apps”. Most
common BIM apps are listed below:
Graphisoft BIMx
Telka BIMSight Mobile
Navigator Pano Review
Autodesk 360 Mobile
Revizto Viewer
BIManywhere
11. BIM – Productivity Rates
IPD vs Traditional methods
of construction in terms of
Cost / Time / Efforts.
(Hijazi, 2015).
12. BIM – Productivity Rates
This graph depicts the total time it takes to
complete a project, by using BIM & CAD
separately.
(Graphisoft, 2015).
Additionally, BIM enabled projects have
reduced the number of RFI’s to 10% of the
project.
(Chelson, 2010).
This reduction of rework and idle time, due
to site conflicts savings for trade
contractors, have been reduced to 9% of
13. BIM – Productivity Rates
Long term & short term rates
when a construction company
is working with BIM and
applying BIM to a construction
project.
(McGrawHill Construction, 2012).
14. BIM – Productivity Rates
Tangible benefits for contractors &
sub-trades working with BIM related
programs and implementing BIM
practices.
(Turner, 2015).
15. BIM – Productivity Rates: Facts from
Studies
75% of BIM users reported better multi-party
communication.
57% of Designers state BIM reduces errors during the
design phase.
Average project duration reduced by 37%.
65% of contractors report BIM reduces rework and cost
16. BIM – Project Turnover Rates
The impact
of BIM on
Project
Turnover
rates
(Becker-Gerber,
2010).
17. BIM – Implementation
Software / Hardware Requirements:
CPU Types:
Multi-Core Intel Pentium, Xeon, or i-Series Porcessor or an AMD equivalent
Memory
4 – 8 GB of RAM
Video Graphics Card
Direct X11 with Shader Model 3 (As recommended by Autodesk)
Staff Training Requirements:
Sufficient Human Capitol to complete the project in a Team Based
environment
A diploma in Architectural Technology (or equivalent diploma) is
usually required.
18. BIM – Challenges
IPD concept education & “Know how”
Understanding each other’s role &
responsibility
Set up communication protocols
Understanding that increase in cost at
early stages can substantially reduce
construction process costs, change
orders and requests for information.
Contractors & sub-contractors need to
revise their construction management &
process.

Jacek Gorka Dipl. Ing., ARCH., M.Arch, OAA, MRAIC - Project Manager
at GorkaArchitects.
Mr.Gorka has been working with CAD & BIM software for the
past 20 years and also has his own practice at GorkaArchitects
“Being a designer and Project Manager, I have noticed that
‘Element Redundancies’ have dropped, which has improved
project productivities. I have also noticed that over the years,
with using BIM practices and the Revit Program, is that
coordination errors have dropped 90% - which has greatly
improved productivity”– (J. Gorka, personal communication, December 2, 2015)
20. Primary Sources – Kaite Kuzan
Katie Kuzan B. AS, M.Arch - Project Manager at Kohn Partnership
Architects Inc.
“The growing trend is that a number of trades have requested
the Architect/Client release the BIM model to perform Quantity
Take-offs at a much faster rate and with ease.”
- (K. Kuzan, personal communication, December 3, 2015).
Ms.Kuzan has also stated that this trend has increased by as
much as 20% within the past years.
She has also stated that this trend is most common within the
Steel Sub-Trade.
21. Primary Sources – Nay Calderon
Ney Calderon, Dipl. Arch. Tech. - Research and Innovation Lab
Technician Coordinator - CCET
“BIM is a great tool to optimize project results, increase project
value for the owner, reduce waste and maximize efficiency
throughout all aspects of the project.” - (N. Calderon, personal communication, December 4, 2015)
Mr. Calderon has stated that the best way utilize BIM to its
fullest potential is to have everyone on board with the process
and for everyone to understand it.
22. BIM – Conclusion & Recommendations
In conclusion BIM can help Construction Companies
Improve visualization of construction projects
Improves productivity due to easy retrieval of information
Increase coordination of construction documents
Embedding and linking of vital information such as vendors for specific
materials, location of details and quantities required for estimation and
tendering
Increased speed of delivery
