2. advices for advancing the productivity of the construction industry:
1. Widespread deployment of Building Information Modeling (BIM)
2. Improved job-site efficiency
3. Greater use of prefabrication, preassembly, modularization, and off-site fabrication techniques.
4. Innovative, widespread use of demonstration installations
5. Effective performance measurement to drive efficiency and support innovation.

3. Manufacturing building components off-site:
More controlled conditions for weather, quality control, improved supervision of labor, easier access to tools, and fewer material deliveries.
Fewer job-site environmental impacts
Compressed project schedules
Fewer conflicts in work crew scheduling and better sequencing of crafts persons.
Reduced requirements for on-site materials storage, and fewer losses of materials.
Increased workers safety.

4. Definition of Modular Construction:
A resource efficient, off-site delivery method to construct code-compliant buildings in a quality-controlled setting

5. Advantages of Modular Construction:
Less Materials Waste
Less Material Exposure to Inclement Weather
Less Site Disturbance
Safer Construction
Flexibility
Adaptability
Built to Code With Shorter Build Times

6. Modular Building Usage:
Permanent Modular Construction
Temporary Buildings
Education
Healthcare
Commercial Housing
Office Administration
Security
Emergency
Workforce housing
Assembling the entire fleet of modules rely on optimization of the crane position
Based on one case study in Muhlenberg college in Pennsylvania , over 90 modular units were delivered in a record time of 10 days by optimizing of crane position.

10. Issues and Impediments about Modular Construction:
Typically 40-50% of modular building construction is left to be completed in the field
Geographic location of the factory
Engineering requirements
Specific dimension or loading limitations due to transportation constraints
Changes in design during manufacturing can be difficult and expensive to accommodate.
the complexity of transportation activity is increased in modular construction.
The increased demand for very effective coordination and communication among participants
For a factory and manufacturer the repetition of prefabricated components is essential in order to meet quantity for cost effectiveness.

11. The regulations set down by transport Quebec:

12. Suitable project delivery system in Modular Construction:
Most modular building projects are fixed-price contracts
many modular construction projects are being completed faster and for less money by utilizing Design-Build or Construction Manager at Risk(CMR).
most architects are not experienced enough in the modular construction
when modular manufacturing is responsible for the design or is involved the project is more likely to be successful.
If projects use Design-Build:
direct line of communication between the owner and modular manufacturer
costs are easier to control
workload upon the owner is increased
publicly funded projects

13. In case of using Design-Bid-Build:
amount of involvement of owner in the project is reduced
if the designer firm is not familiar with modular construction it could bring high initial cost to the project
because of additional layers of communication the project duration would be increased
in case of using CMR:
it works very well when the modular company is either the construction manager or is a key subcontractor with a design assist role.

14. Implementation of BIM in Modular Construction:
The MEP coordination and fabrication process
extensive demand of pre project planning
Implementation of BIM systems in modular construction:
Visualization
Modeling
Code reviews
Fabrication/ shop drawings
Communication
Cost estimating
Construction sequences
Conflict, interference and collision detection

15. six factors which influence the productivity of Nuclear Power Plants:
low material availability
low tool availability
high rework rates
needless interference with other crews
overcrowded work areas and time consuming inspection delays
Reducing the amount of on-site labor with factory produced power plant modules
