- 4. Chapter 1 Introduction to Formwork 4
- 5. 1. Introduction: 1.1 Definition of Formwork: When concrete
is placed, it is in plastic state. It requires to be supported by
temporary supports and castings of desired shape till it becomes
sufficiently strong to support its own weight. This temporary
casing is known as the formwork or forms or shuttering. 1.2 General
Introduction: Formwork plays a key role in concrete construction.
Forms are the moulds & dies of concrete construction. They
mould the concrete to the desired size & shape & control
its alignment & position. Formwork also carries the weight of
freshly placed concrete and itself besides live load due to
materials, equipment and workmen 5
- 6. 1.3 Importance of Formwork: In the Construction of any
building concreting and reinforcement binding is the main activity
after that to hold them in their position Formwork is most
important Formwork constitutes 20% of the standard cost and 60% of
the time in concrete construction. Thus a good formwork system
helps in achieving speed, quality, economy and safety in reinforced
concrete construction 6
- 7. 1.4 Requirement of Formwork: To obtain the required shape,
size, finish, position and alignment of concrete members. To have
enough load carrying, or transferring capacity to take pressure or
weight of fresh concrete and any other loads, without distortion,
deflection, leakage, failure or danger to workmen. To have design
for quick erection and removal. To handle easily using available
equipment or manpower. Joints between formwork must be tight enough
to prevent leakage of grout.
- 8. 1.5 Based on material Various Types of Formwork are :
Plywood (Fig-1.1) Bamboo (Fig-1.2) Steel (Fig-1.3) Aluminium
(Fig-1.4) Plastic (Fig-1.5) 8

- 14. Chapter 2 Mivan Formwork System 14
- 15. 15
- 16. 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. Early removal
of forms can be achieved by hot air curing / curing compounds. This
facilitates fast construction, say two flats per day. 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. 16
- 17. Fig-2.1 Wall Assembly Details 2.3 Mivan Formwork Assembly:
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.
17
- 18. Chapter - 3 Procedure For Using Mivan Formwork 18
- 19. 3.0 Procedure For Using Mivan Formwork: 3.1 PRE CONCRETE
ACTIVITIES: a) Receipt of Equipment on Site The equipments is
received in the site as ordered. b) Level Surveys Level checking
are made to maintain horizontal level check. c) Setting Out The
setting out of the formwork is done. d) Control / Correction of
Deviation Deviation or any correction are carried out. e) Erect
Formwork The formwork is erected on site. f) Erect Deck Formwork
Deck is erected for labours to work. g) Setting Kickers kickers are
provided over the beam. 19
- 20. i. Dislodging of pins/wedges due to vibration. ii.
Beam/deck props adjacent to drop areas slipping due to vibration.
iii. Ensure all bracing at special areas slipping due to vibration.
iv. Overspill of concrete at window opening etc. 3.2 ON CONCRETE
ACTIVITIES: 20
- 21. A) CLEANING: All components should be cleaned with scrapers
and wire brushes as soon as they are struck. Wire brush is to be
used on side rails only. B) TRANSPORTING: The heaviest and the
longest, which is a full height of wall panel, can be carried up
the nearest stairway. Passes through void areas. C) STRIKING: Once
cleaned and transported to the next point of erection, panels
should be stacked at right place and in right order. D. Erecting of
Formwork: After that formwork is erect again on the next floor. 3.3

Construction (Work Cycle): 5.1 Design Aspects of Mivan: 5.1.1
Buildings are compared as: i) Conventional RC columns, beams, and
slab construction (RC moment resisting framed structure) ii) RC
load-bearing walls and slabs.
- 46. 5.3 Work cycle: 5.3.1 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. 46
- 47. Fig-5.4.1: Building Finishes Due To Mivan Formwork 5.4
Quality Advantage of Mivan: High quality Formwork panels ensure
consistency of dimensions. The high tolerance of the finish means
that no further plastering is required.
- 48. 5.5 The Advantages of Mivan Formwork system: The MIVAN
formwork is specifically designed to allow rapid construction of
all types of architectural layouts. 1) Cost effective. 2) It is
more effective for mass housing to be done quickly. 3) Great
construction speed. 4) High quality finish. 5) Erected using
unskilled labor. 6) Panels can be reused up to 250 times. 48
- 49. 5.6 Limitation of Mivan Formwork: 1) Because of small sizes
finishing lines are seen on the concrete surfaces. 2) It requires
uniform planning as well as uniform elevations to be cost
effective. 3) Modifications are not possible as all members are
caste in RCC. 4) Due to box-type construction shrinkage cracks are
likely to appear. 5) Heat of Hydration is high due to shear walls.

- 172. Summary: The structural form of the building is one of the
critical factors to determine the choice of formwork System
products contribute much in the success of formwork application The
choice and arrangement of utilizing formwork is highly depended on
individual site/project environment More collaboration between
client, design teams and contractor can help in the effective use
of more advance formwork systems
