Influence of BIM on Industry
Problems
63

Influence of BIM on Industry Problems
Problem: Design Visualization and Communication
BIM solution: Visualize your Design and Communicate it better
 Using the better visualization
tools the design can be easily
communicated to the non
technical client.
 Changes can easily be
incorporated in design using
client feedback, reducing
change orders thus overall
cost of the project.
 More time is spent designing
than drafting.
64

 Increased client satisfaction
through more effective
communications.
Problem: Design Communication Within Teams
BIM Solution: Improved Design Communication
(BIM)
65

 BIM ensures better
communication between
different stake holders.
Problem: Design Communication With stakeholders
66

 Instead of 2D drawings
information is shared in the
form of BIM model which
clearly communicate the
design intent to all
stakeholders which are
involved in a building lifecycle.
Problem: Design Communication With stakeholders
67

Problem: Coordination
BIM Solution: Improved Coordination and Clash Detection
 Better visualization during
design, coordinated drawings
and clash detection tools
reduces clashes between
various elements which causes
delay in construction work
resulting in increase of the
budget as well as client
dissatisfaction from the
building makers.
68

 Better visualization during

dissatisfaction from the
building makers.
Problem: Coordination
BIM Solution: Improved Coordination and Clash Detection
69

Problem: Cost Uncertainty
BIM Solution: Greater predictability
 BIM automates the quantity
extraction process.
 Different design options and
there impact on cost can be
obtained easily without much
effort and in less time.
 Material usage at different
stages of the project can also
be tracked using BIM.
70

Problem: Unsafe Construction Site
BIM Solution: Better Safety Planning
 BIM also improves the safety
situation of site.
 Different possible situations
can be simulated using the
BIM tools so that proper safety
plans can be designed
according.
71

Problem: Less Prefabrication more Onsite work
BIM Solution: Design Accurately , More prefabrication
 BIM allows accurate design which
increases ability to prefabricate.
 Like a "spell - check" device, the
computer tells engineers if parts don't
fit.
 Different components of building can
be manufactured first and installed
later at the site.
 Improves quality and reduces time
and cost.

Problem: Poor Facility Management Data
BIM Solution: All building data at one place!
 Using BIM the facility data as
well as Operation Manuals of
different building
components can all be
stored in one single model.
 This data can be used for
renovation as well as
maintenance.
87

 Buildings around the globe consume about 48% of
the total electricity produced.
 Need of Green Buildings to decrease the demand.
Energy Consumption by Buildings
88

Impact of Construction Industry on Climatic Changes
 The report, “Hot Cities: battle-ground for climate change" from the United
Nations Human Settlement Program, or UN-HABITAT, shows that while the
world's cities only cover 2 % of global land area, they account for a
staggering 70 % of greenhouse-gas emissions.
 If half of new commercial buildings were built to use 50% less energy, it would
save over 6 million metric tons of CO2 annually for the life of the buildings—the
equivalent of taking more than 1 million cars off the road every year.
89

Importance of Green buildings for Pakistan
 Pakistan with 2.56% of world population contributes only 0.8% to global
GHG (Green House Gases) emissions yet ranks 16th on Climatic Change
Vulnerability Index.
 Pakistan was most affected country for 2010.
 Climatic Changes costing economy $14 Billion a year (35.6% of economy-
2014-2015)
 Frequent Floods and Droughts.
90

 BIM allows energy
analysis for sustainable
design at early phase of
design.
 Energy analysis of
different design options
can be easily performed
making the final building
more green.
