2. • The modular construction industry has made
signifi ant advances in implementing processes
and materials to build and deliver more
sophisticated and complex facility types.
• Modular for multi-story, steel framed structures
are becoming more popular.

3. • Modular for health care
• educational structures,
• and large scale military
projects

4. Modular
Construction
• Always known for its time saving advantages,
• modular is now being recognized for being a
more resource efficient, inherently greener
process.
Modular
Construction
• Studies focusing on construction efficiency
have documented 25 to 50 percent waste in
coordinating labour and in managing, moving,
and installing materials.

5. Modular
Construction
• Opportunities for Breakthrough
Improvements
1
• Widespread deployment and use of
interoperable technology applications, also
called Building Information Modelling (BIM);

6. 2
• Improved job-site efficiency through more
effective interfacing of people, processes,
materials, equipment, and information;
3
• Greater use of prefabrication,
preassembly, modularization, and off-site
fabrication techniques and processes;

7. 4
• Innovative, widespread use of
demonstration installations;
5
• Effective performance
measurement to drive efficiency
and support innovation.

8.  Manufacturing building
components off-site provides for
more controlled conditions and
allows for improved quality and
precision in the fabrication of the
component.”

9. Modular
Construction
• The five activities are interrelated, and the
implementation of each will enable that of the
• others.
Modular
Construction
• There must be a strategic, collaborative
approach towards these five approaches

11. Construction productivity—at what cost and quality
buildings and infrastructure can be constructed
The construction industry itself is a major generator
of jobs and contributes an important
component of the gross domestic product (GDP)

12. Changes in building design, construction, and
renovation, and in building materials recycling will
influence:
Cost and quality directly affects prices for homes
and consumer goods and the robustness of
the national economy.

13. 2-reduction in overall energy use
3-reduction in greenhouse gas emissions
1-the environmental impacts from
building activities

14. 1.Widespread deployment
and use of interoperable
technology applications, also
called Building Information
Modelling (BIM).

15. Is the ability to manage
and communicate
electronic data among
people such as:

16. owners clients,
contractorsSuppliers

17. and across a project’s
design, engineering,
operations, project
management, construction,
financial, and legal units

18. This has been made possible by a range of
information technology tools and applications
including:
computer-aided design and drafting (CADD)
three– and four–dimensional visualization and
modelling programs
laser scanning
cost-estimating and scheduling tools
materials tracking.

19. integrated
collaborative
processes
effective
planning up
front

20. integrate processes
manage supply chains sequence work fl ow
improve the quality and speed of project
related decision making

21. reduce design and engineering conflicts
Reduction or elimination of rework
improve data accuracy
reduce the time spent on data entry

22. legal issues
data-storage capacities
Barriers:
improves the life–cycle management of buildings
and infrastructure

23. Finally -to be able to make real-time
information available for on-site decision
making.
need for “intelligent” search applications to
sort quickly through thousands of data
elements

24. people, processes, materials,
equipment, and information.
Improved job-site efficiency through
more effective interfacing of:

25. Managing these activities and
demands to achieve the
maximum efficiency from the
available resources is difficult
and typically not done well.

26.  Greater use of automated equipment (e.g., for
excavation and earthmoving operations,
concrete placement, pipe installation)
 information technologies (e.g., radio-frequency
identification tags for tracking materials,
personal digital assistants for capturing field
data);
 process improvements
 the provision of real–time information for
improved management at the job site could
significantly cut waste
 Can improve job–site safety
 improve the quality of projects

27. the segmentation

proficiencies

29. Greater use of:
 Prefabrication
 Preassembly
 Modularization
 off-site fabrication techniques and
processes

30. Advantages:
 lower project costs
 shorter schedules
 improved quality
 More efficient use of labour and
materials

31. building codes
that hinder
innovation
conventional
design and
construction
processes and
practices

32. Innovative, widespread use of demonstration
Installations
 field testing on a job site;
 seminars, training, and conferences;
 scientific laboratories with sophisticated
equipment and standardized testing and
reporting protocols.

33.  Demonstration Installations can be used to
show the effectiveness of:
 new processes
 technologies
 materials and their readiness to be deployed
throughout the construction industry.

34.  By allowing determinations to be made about
whether innovative approaches are mature
enough for general use
 demonstration installations can help to
mitigate innovation– related risks to owners,
contractors, and subcontractors.

35. Effective performance measurement to drive
efficiency and support innovation
 Performance measures are enablers of
innovation and of corrective actions
throughout a project’s life cycle.

36. They can help companies and organizations
understand issues such as:
 how processes or practices led to success or
failure, improvements or inefficiencies, and
how to use that knowledge to improve
products, processes, and the outcomes of
active projects.
