3. INTRODUCTION
• Monolithic concrete construction system is a prefabrication technology in which instead of
traditional column and beam construction; all walls, floors, slabs, columns, beams, stairs, together
with door and window openings are cast in place in one operation at site by use of specially
designed, easy to handle (with minimum labour and without use of any equipment) modular form
work made of Aluminium Plastic composite.
• MEP services can also be placed into the walls before pouring of concrete, thus preventing the need
of additional framing in the interior of the building.
• This system is used for constructing high-rise vertical buildings as well as low-cost mass housing.

4. Continued…
• This technology originated from Malaysia as Mivan formwork system.
• Mivan is a quality aluminium structure developed by a European construction company
known as Mivan Company Limited.
• In 1990, the company from Malaysia began manufacturing these formwork systems.

5. WORKING PRINCIPLE
• It works on rapid construction cycle with production line process approach.
• The structure is designed as RC load-bearing shear walls and slabs. Monolithic casting of slabs
along with RC walls results in box type structure which is very strong and resist horizontal forces
due to wind and earthquakes.
• The engineered formwork system is designed based on the drawing of the structure and
manufactured in the factory.
• The formwork can be used for more than 200 times and one floor can be constructed in 4 to 5 days
with aluminium formwork and in 20 to 21 days with conventional (wooden) formwork.
• In case of double or single story house, build cycle is sometimes 1 house per day.
• While transporting, all panels are clearly labelled for easy identification on site and smooth fitting
using formwork modulation drawing.

• These are made up of extruded aluminium or composite section.
• Welded aluminium composite sheet made of high-strength aluminium alloys with 4 mm
thick skin plate and 6 mm thick ribbing behind to stiffen the panels.

12. CONSTRUCTION PROCESS
Erection of vertical reinforcement and one side of vertical formwork for the entire floor.
Erection of second side of the vertical formwork and formwork of the
floor.
Fixing reinforcement bars for floors and slabs, and
casting of walls and slabs.
Removal of vertical formwork panels
after 24 hours but leaving the props,
and moving into another floor.

13. ADVANTAGES
• Specially designed to allow rapid construction of all types of architectural layout for same built-up
area, and more carpet area is achieved compared to conventional brick masonry.
• Since the entire structure is closed in and protected from weather, interior finishing moves ahead
without getting affected due to weather conditions.
• Erection does not require highly skilled labours.
• Walls are complete and ready for treatment as soon as forms are stripped.
• With proper use, more numbers of repetition is possible.
• It is recyclable after use, scrap value is also high.
• Less debris generated.
• Overall embodied energy in monolithic concrete structure has been found to be lower than the
conventional brick masonry.

14. LIMITATIONS
• Requires uniform planning as well as uniform elevation to be cost-effective.
• Lead time of about three months is required to initiate the construction.
• Capital cost is high and need to be planned in advance for smooth progress of work.
• Curing requirement increases.
• If only OPC is used, due to box type construction shrinkage cracks will be more.
• Post construction modification is not possible.
• Large number of repetitions are required to be cost-effective, therefore volume of
construction should be large.

15. USAGE IN INDIA
• This technology has not been used widely in India but is very popular in Gulf countries, Europe,
and some parts of Asia.
• There are a number of buildings in Mumbai that are being constructed using this technology,
which has been declared economical as well as satisfying for the overall Indian real estate market.
• Some major projects completed using this technology in India are:
 Houses in Gurugram for CRPF.
 Houses in Bangalore for Bangalore Development Authority.
 Houses in Mysore for Karnataka Slum Development Board.
 Houses in Bangalore for Karnataka Slum Clearance Board, etc.
• Its use is being preferred in India to complete the most challenging government scheme – Housing
for all by 2022.

16. CONCLUSION
• CPWD has already adopted this technology and is using it for its projects.
• NBC, CPWD schedule of rates, and BMTPC performance appraisal certificate has
strengthened the technological base for this system and is gradually gaining popularity in
different states of India.
• This formwork system has emerged as one of the accepted emerging technology for mass
housing.
• In spite of some limitations which can be overcome easily with proper planning, this
construction system brings speed, quality and durability, and economy in construction.
• Such systems are key to meeting the demand for efficient sustainable mass housing.
