OUTLINE OF PRESENTATION

3.  Mivan is the Brand name from far East,Malaysia.
 It is Alluminium Alloy Formwork.
 The system of Aluminium forms (MIVAN) has been used widely in
the construction of residential units and mass housing projects.
 It is fast, simple, adaptable and cost – effective. It produces total
quality work which requires minimum maintenance and when
durability is the prime consideration.
 This system is most suitable for Indian condition as a tailor–made
aluminum formwork for cast–in–situ fully concrete structure.
 Aluminum Formwork system is a comparatively a new technology in
India.
WHAT IS MIVAN FORMWORK?

4.  Mivan is basically an aluminum formwork system developed by one of
the construction company from Europe. In 1990, the Mivan Company Ltd
from Malaysia started the manufacturing of such formwork systems.
 Now a days more than 30,000 sq. m of formwork used in the world are
under their operation. In Mumbai, India there are number of buildings
constructed with the help of the above system which has been proved to
be very economical and satisfactory for Indian Construction Environment.
 The technology has been used extensively in other countries such as
Europe, Gulf Countries, Asia and all other parts of the world.
HISTORY & BACKGROUND

5. WHEN IT IS SUITABLE ..?
 Mass Housing
 No. of Repetitions Are More
 Typical Floors
 Fast Construction Required
 High Quality
 Column Less Structure
 Highly Suitable To Load Bearing Structure (Shear wall)

6.  MIVAN aims in using modern construction techniques and
equipment in all its projects. On leaving the MIVAN factory all
panels are clearly labeled to ensure that they are easily
identifiable on site and can be smoothly fitted together using the
formwork modulation drawings. All formwork begins at a corner
and proceeds from there.

 SIMPLICITY – PIN AND WEDGE SYSTEM
The panels are held in position by a simple pin and wedge system that
passes through holes in the outside rib of each panel. The panels fit
precisely, simply and securely and require no bracing.
FORMWORK ASSEMBLY

8. COMPONENTS OF MIVAN FORMWORK
 The basic element of the formwork is the panel, which is an extruded
aluminum rail section, welded to an aluminum sheet. This produces a
lightweight panel with an excellent stiffness to weight ratio, yielding
minimum deflection under concrete loading. Panels are manufactured
in the size and shape to suit the requirements of specific projects.
 The panels are made from high strength aluminum alloy with a 4 mm
thick skin plate and 6mm thick ribbing behind to stiffen the panels. The
panels are manufactured in MIVAN’S dedicated factories in Europe and
South East Asia. Once they are assembled they are subjected to a trial
erection in order to eliminate any dimensional or on site problems.
 All the formwork components are received at the site within three
months after they are ordered. Following are the components that are
regularly used in the construction.

14. SPEED OF CONSTRUCTION -WORK CYCLE

15. SPEED OF CONSTRUCTION – WORK CYCLE
The system usually follows a four day cycle: -
 Day 1: -The first activity consists of erection of vertical
reinforcement bars and one side of the vertical formwork for the
entire floor or a part of one floor.
 Day 2: -The second activity involves erection of the second
side of the vertical formwork and formwork for the floor
 Day 3: - Fixing reinforcement bars for floor slabs and casting of
walls and slabs.
 Day 4: -Removal of vertical form work panels after 24hours,
leaving the props in place for 7 days and floor slab formwork in
place for 2.5 days.

16. SPEED OF CONSTRUCTION – WORK CYCLE
System for scheduling & controlling the work of other connected
construction trades
Deshuttering of the panels – 12 to 15 hrs
Positioning brackets & platforms on the level- 10 to 15 hrs
Deshuttered panels lifted & fixed on floor-7 to 10 hrs
Kicker & external shutters fixed in -7 hrs
Shutters are erected in 6-8 hrs
Reinforcement – 10 to 12 hrs
Electrical fittings -10 hrs
Pouring concrete

18. QUALITY ADVANTAGE OFMIVAN
The Advantages of this system are :-
The MIVAN formwork is specifically designed to allow rapid construction
of all types of architectural layouts.
 1) Total system forms the complete concrete structure.
 2) Custom designed to suit project requirements.
 3) Unsurpassed construction speed.
 4) High quality finish.
 5) Cost effective.
 6) Panels can be reused up to 250 times.
 7) Erected using unskilled labor.

19. OTHER ADVANTAGE OFMIVAN
 Easy to handle.
 Aluminum does not rust like steel; therefore, the Aluminiumformwork
can be reused hundreds of times.
 Formwork is made with an aluminium alloy, which has high tensile
strength and is also very hard.
 Saving on overhead expenses due to speedy construction.
 Doesn’t require timber or plywood for construction activities so, it
saves the environment.
 Casting of walls and slabs possible simultaneously.
 Less debris generation.
 Higher scrap value.
 Carpet area will increase.
 Collect the best premium from the customer, because of 100% RCC
buildings.

20. LIMITATIONS OF MIVAN FORMWORK
o Even though there are so many advantages of MIVAN formwork the
limitations cannot be ignored.
o It requires uniform planning as well as uniform elevations to be cost
effective. and skilled labor required.
o Large volume of work is necessary to be cost effective i.e. at least
200 repetitions of the forms should be possible at work.
o Architectural changes not possible on the structure (but some walls
can be of brick work or openings can be entertained).
o Number of holes will be more in the vertical wall, outer wall which is in
direct contact with the rain, hole should be grouted by Non Shrink
compound.

21. CONCLUSION

The intension of this paper is not provide a detailed comparison
or explain the technical features of Mivan formwork system in
depth. Instead of it aims to show the overview, condition &
constraints governing the use of Mivan formwork system under
the typical local circumstances.
 It can be concluded that the modern methods of construction
such as 'Mivan formwork system' are the key to meeting the
demand for efficient, sustainable housing. Also the quality and
speed must be given due consideration with regards to
economy.
