15. Advanced Safety screen covering 2.5 Floors full protection
First time in India
Minerva Tower Lodha Wadala

16. MIAL ATC Tower
Airport Viewing Gallery in ATC Tower
• India’s tallest Air Traffic Control (ATC)
Tower at 83.8 m height for MIAL Project.
• Complicated Structure constructed with
In-house Climbing Systems
• Received ICI McBauchemie Award 2013
for Outstanding Concrete Structure

17. Top Down Construction Technology
Conventional way of construction is the process of
taking up the buildings works in sequence from
foundation till the final super structure level is
reached.
In Top Down Construction, the structure is taken up
from the upper levels and progress
incrementally till the bottom level or founding
level is reached.
Advantages
• Faster Execution: Sub and Super Structure
works can be constructed simultaneously.
• High quality: Improved quality due to composite
and precast structures.
• Cost Savings: Time is money. Simultaneous
works execution reduces overall cost.
• Minimal Foot print in the ground.

18. Weld Mesh System
High Productivity Minimal Workmen
Better Rebar Bonding Cost Savings

19. 18,000 MT of erection
Structural Erection @ DIAL Project
• First Time in India
• 18000 MT of Structural Steel Works
• Roof truss erection using 16 Strand Jacks with remote control
• Max. weight of Single Lift - 600 MT

22. Glass Fibre Reinforced Gypsum (GFRG) for Finishes
 Innovative light weight material
 Most suitable for complicated
profiles & geometry
 Superior finish for indoor interior
 Construction friendly installations
 Maintenance free

23. Concrete Technology
Self Compacting Concrete
 Used to achieve Architectural forms and
corrugated elements.
 Consistency in surface texture of MIAL -
ATC Sky Tower profile stands as a
testimony for this technique.
Quick Set Concrete
 Quick Set concrete was used for
encasing of ducts and pipes for Runway
and allied taxiway lighting system.
 This ensured aircraft landing within 6Hrs
commencement of work.
Light weight Concrete
 Light weight concrete of density
10KN/cum.
 For roof slopes with reduced dead loads.
 Roof slopes & land scape areas.
Fiber Reinforced Concrete
 Fiber reinforced concrete (With Steel /
Polypropylene) used for high strength
flooring applications for warehouses &
Factories.
 Flexural strength - 5.5 to 7 Mpa.

24. 3D Design Studios
 State-of-the-art fully functional 3D Studio - ‘Srishti’ and ‘Dristhi’ at Chennai &
Mumbai - where ideas are born & synergized and designs translated into
virtual reality.
 Features like virtual prototyping, walk-throughs and analysis by controlling virtual
models including design reviews give the customer a feel of the actual project
before execution.
