The document discusses a tunnel formwork system for constructing concrete buildings. The system uses reusable modular steel forms to cast walls and slabs in one daily cycle, reducing construction time compared to conventional methods. It provides smooth concrete surfaces, dimensional accuracy, and load-bearing earthquake-resistant structures. The system offers savings in workmanship, finishing works, and duration of up to 50% and the forms can be reused up to 500 times.

TUNNEL FORMWORK SYSTEM
•Tunnel Formwork System
provides fast project completion
with least workmanship costs.
•Smooth concrete surfaces and
dimensional accuracy eliminates
finishing works like plastering

5. •The system creates efficient load-
bearing structures which are known as
the most earthquake resistant structures.

6. Tunnel formwork is a system that
allows casting of walls and slabs
in one operation on a daily cycle.
Construction durations are
reduced significantly by this rapid
system when compared to
conventional methods. Tunnel
form system brings speed, quality
and accuracy to concrete
construction and provides big
savings in finishing and M&E
works.

7. The savings from less
workmanship & duration can
reach up to almost 50%. Tunnel
form can be reused up to 500
times without any reconditioning.
Hi-tech technologies for steel
formwork production make
tunnel forms strong & durable.

“After Sales Service” is an integral part of MESA
IMALAT’s company policy.
Our experienced technical personnel will be at
our customer’s service on-site wherever their
project is located around the world.
At all projects the assembly of formwork and first
casting of concrete will take place under the
supervision of MESA IMALAT’s technical staff. In
this manner not only the correct implementation
of the system is secured but also training of
contractor’s site personnel is done.

17. In accordance with our quality system and customer-
oriented service policy the maximum importance is given
for the training of MESA personnel. In the meantime
MESA IMALAT offers to her customers training &
certification programmes related to safe and proper
implementation of formwork systems.

18. DAILY CYCLE
TUNNEL FORMWORK SYSTEM
FORMWORK SYSTEMS

19. Foundation completed as
per construction drawings.
Reinforcement wire mesh & bars of the
concrete walls are installed
First half-tunnel is taken to place by crane
in accordance to the formwork layout.
Bottom of tunnel form is set levelled with
the line on the kickers by the help of the
jacks mounted on the vertical panels.
Block-outs for door/window openings are
assembled on vertical surface. Electrical
conduits are installed. Cones and tie rods
are placed.
Before the first casting with tunnel form,
kickers should be cast in order to position
the load bearing concrete walls.

20. DAILY CYCLE
Slab reinforcement mesh/bars are installed.
Kicker forms for next level are fixed on the
tunnels. Final checks are performed before
concreting. Insulation curtains are placed
for night-time heating at cold weathers.
2nd Half Tunnel is taken to its place. Block-outs
are assembled .The verticality of the half tunnels
is set using the triangulation wheel. Two half
tunnels are locked by the roof locks. Cones &
tie-rods are placed.
All tunnel form units for the 1st phase are
located as explained above. End-wall forms
are positioned. After adjusting verticality tie-
rods are fastened. Horizontal surface is
oiled. Electrical conduits are installed.
Block-outs for slab openings and slab/wall
stop-ends are set in place.

21. 2nd half-tunnel shall be removed after back
propping first half. Stripping & gable-end
platforms are also assembled around the
perimeter of the building. Tunnel forms will
be stripped-out on those platforms starting
from first floor.
Next morning starts with stripping of tunnel forms.
Also reinforcement mesh & bars are installed for
the next phase. Half tunnels are loosen from
connecting components and block-outs. Half
tunnels are moved on the rollers and pulled-out
by the crane to the next phase/level by the help of
lifting triangle.Vertical panel surface is cleaned
and oiled while stripping the half-tunnel.
Concreting done starting from first inside walls
towards end walls and finally slab concrete.
Plastic curtains are closed and each unit is
heated by simple heaters throughout the night
for curing purpose at cold weather.
At every span the slab is back-propped after
first half tunnel is removed.

22. ADVANTAGES OF MODULAR-ERTF
Bottom tie-rod locations on tunnel forms are elevated to
ensure that kicker concrete would remain below this
level even after any uncontrolled casting of kicker.
Kicker forms in bigger section enable long-lasting quality
implementation.
Standard size back-panels can easily be adapted
to any span by using extension panels. In this way
panels can easily be reused at new projects.
It eliminates the need for back-panels with special
dimensions.
Provides better concrete finish at joints of
extensions panels
Height kickers makes it easier to adjust tunnel heights
which eliminates levelling mistakes of the foundation.

23. Enables to use the same platform at several
floors with different slab finish lines.
For slabs with poor concrete finishing,
assembly of platform requires less
workmanship since the timber surface is
inserted under the slab
Half-tunnels can easily be moved and
stripped on platforms by the help of rollers
which are used instead of wheels. It is
placed under vertical panel of half-tunnels
above the slab.
It reduces vertical panel price by
cancelling the wheels and also simplify
storage of vertical panels.
Formwork weight will not affect stripping
platform as the tunnel forms are carried by
the rollers during their movement.

24. ADVANTAGES OF MODULAR-ERTF
Vertical panels are produced in standard heights.
It can be used for half-tunnels and also for end-walls
which reduces different types of panels on site.
Vertical panels are used with upper extension panels
to reach different floor heights easily. In this way
panels can easily be reused at new projects.
Vertical panels can be used as wall-forms too.
Asymmetrical Lifting Triangle
The lifting triangle is designed so that it can be set in
place with the centre of gravity of the tunnel still inside
the building by the help of its asymmetrical shape.
In this way the load of tunnels which are moved on
the rollers won't be taken by the stripping platforms.
Easier to handle and transport than classic lifting
triangles.

25. ERTF Telescopic Push-Pull Prop
Standard push-pull props can easily be used at
any tunnel span by the help of its telescopic
design. It eliminates the need for several different
types of props.
ERTF Push-Pull Props makes it very easy to adjust
the height & level horizontal panels of tunnel form.
Lifting up the the control arm will simply move the
horizontal panel down. The arm is locked once
the panel is adjusted properly.
Modular Horizontal Panel
with Extension Adapter
Horizontal panels are produced in standard
width and can be used at any span
dimension with extension adapter panels.
In this way panels can easily be reused
at new projects.
It eliminates the need for back-panels with
special dimensions.
Provides better concrete finish at joints of
extension panels.
