FORMWORK
• Formwork is the temporary moulds or shutters in
which concrete is placed, so that it will have desired
shape or outline when hardened. This temporary
casing is known as Formwork orShuttering.

3. WHAT IS MIVAN
FORMWORK
 Mivan is the Brand name from far East,Malaysia.
 It is Aluminium 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.
 Aluminum Formwork system is a comparatively a
new technology in India.

4. HISTORY &
BACKGROUND
 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.
MIVAN technology is suitable for constructing large number of
houses within short time using room size forms to construct walls
and slabs in one continuous pour on concrete.
 All the activities are planned in assembly line manner and hence
result into more accurate, well – controlled and high quality
production at optimum cost and in shortest possible time.

5. WHEN IT IS SUITABLE
 3S–System of Construction –Speed,Strength,
Safety.
 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)

13. ADVANTAGES OF MIVAN
FORMWORK
• More seismic resistance:-Thebox type construction providesmore seismic
resistance to thestructure.
• Increased durability: -Thedurability of acomplete concrete structure ismore
than conventional brick bat masonry.
• Lessernumber of joints thereby reducing the leakages and enhancing the
durability.
• Higher carpet area- Due to shearwalls the walls arethin thus increasing area.
• Integral and smooth finishing of wall and slab-Smooth finish of aluminum canbe
seen vividly onwalls.
• Negligible maintenance –Strongbuilt upof concrete needsno maintenance.
• Fastercompletion –Unsurpassedconstruction speedcanbe achieved dueto
light weight of forms.
• Lessermanuallabour- Lesslabour isrequired for carrying formworks.
• Simplified foundation design dueto consistent load distribution.

14. LIMITATIONS
• Because of small sizes finishing lines are seen on the concrete
surfaces.
• Concealed services become difficult due to small thickness of
components.
• It requires uniform planning as well as uniform elevations to be
cost effective.
• Modifications are not possible as all members are caste in RCC.
• Large volume of work is necessary to be cost effective i.e. at least
200 repetitions of the forms should be possible at work.
• The formwork requires number of spacer, wall ties etc. which are
placed @ 2 feet c/c; these create problems such as seepage,
leakages during monsoon.
• Due to box-type construction shrinkage cracks are likely to appear.
• Heat of Hydration is high due to shear walls.
