This document discusses modular construction. It defines modular construction as structures made off-site from prefabricated components that are assembled on-site. It covers the application of modular construction in housing, education, and healthcare. It describes the types as permanent modular construction and relocatable buildings. The benefits are listed as reduced costs, improved quality, sustainability, and reduced construction time. The limitations include transportation challenges and need for skilled labor. A case study of modular apartments in San Jose, California is presented.

3. WHAT IS MODULAR CONSTRUCTION
 “Modular Construction is a pre-engineered process of making any structures or
elements in a factory that is off-site and are delivered to the sites and assembled
as large volumetric components or as substantial elements of any structures.”
 Modular construction in case of Buildings are generally six sided boxes called
Modules, they can be joined side by side or on top of each other. The Modular
buildings should have a Roof, Floor, Walls etc. These Modules are constructed in a
factory to various levels of completion from Basic Modules to completely fitted
rooms that are fully functional.

5. APPLICATION OF MODULAR CONSTRUCTION
 Private housing
 Social housing
 Apartments
 Education sector and student residences
 Health sector buildings
 Hotels

6. TYPES OF MODULAR CONSTRUCTION
 Permanent Modular Construction (PMC)
 Re-locatable Buildings

7. WHY MODULAR CONSTRUCTION
 One of the major reason to adopt modular construction is that not only can one
save up to 35% on the initial construction costs like labour and materials, but there
are other benefits as well.
 Another major reason is about the quality as one can attain a suitable quality in
the elements of any structures that are to be pre-fabricated or pre-cast in the
construction factory.
 Modular construction takes most of the construction phase away from the
building site. Quicker and efficient factory processes are replacing the slow, less
productive site activities.
 Sustainability in modular construction can be achieved through the factory
production of the modular units .
 For a modular construction project to complete with a good result, proper
planning, coordination and communication must exist between various relevant
parties involved from the early stage of the project.

8. PLANNING TRAFFIC ROUTE
 How long transporter vehicle is
required?
 What is the required load capacity of
the transporter vehicle?
 What is the maximum vertical
extension of the shipment?
 Routs on the site?
 Is route permission
required?

9. MODULAR CONSTRUCTION PROCESS
Process in modular construction :
1. Designing the structure
2. Engineering review
3. Permit and approvals
4. Site development
5. Plant fabrication
6. Transportation
7. Installation

10. COMPARISON
SITE-CAST
 No transportation.
 The size limitation is depending on
the elevation capacity only.
 Lower quality because directly
affected by weather.
 Proper, large free space required.
PRECAST AT PLANT
 Transportation and elevation capacity
limits the size.
 Higher, industrialized quality less
affected by weather.
 No space requirement on the site for
fabrication.
 Unlimited opportunities of
architectural appearance.
 Option of standardized components.

Reduced Construction Time

12. BENEFITS OF MODULAR CONSTRUCTION
 Greater Flexibility and Reuse
 Less Material Waste
 Improved Air Quality
 Reduced Construction Schedule
 Elimination of Weather Delays
 Built to Code with Quality Materials
 Safer Construction
 Faster Construction
 Quality Construction
 Eco-Friendly

13. DRAWBACKS OF MODULAR CONSTRUCTIONS
 Handling and transportation may cause breakages of members during the transit
and extra provision is to be made.
 Difficulty in connecting precast units so as to produce same effect as monolithic.
This leads to non-monolithic construction.
 They are to be exactly placed in position, otherwise the loads coming on them are
likely to get changed and the member may be affected.
 High transport cost.
 Need of erection equipment.
 Skilled labour and supervision is required.

14. CONCLUSION
 The use of precast concrete construction can significantly reduce the amount of
construction waste generated on construction sites.
 Reduce adverse environmental impact on sites.
 Enhance quality control of concreting work.
 Reduce the amount of site labour.
 Increase worker safety .
