2. LITERATURE CASE STUDY:
INSTACON TOWER, MOHALI

3. INTRODUCTION
• LOCATION: Mohali, Punjab, India.
• COMPLETED ON: December 1, 2012.
• DEVELOPER: Synergy Thrislington, a Mohali-based
infrastructure company.
• SIZE OF THE PROJECT: 2,553.60 sq m
• The first building of its kind in India, the structure
was built with the assistance of three cranes and
more than 200 highly skilled technicians and workers.
• A dead load of 1,200-1,500 kg sq m along with a live
350 kg sq m, the 48-hour masterwork stands tall in
this vibrant city.
• COSTS: 8-9 Crore.
• It required 40-60 days for Instacon's units to be
manufactured in the factory.

5. BUILDING MATERIALS:
• The external structure of the building comprises double-
skinned PUF panel (PVDF galvalume coated sheet) that
ensures thermal insulation.
• The core material used is mild steel, which is lightweight,
strong, flexible and environment-friendly.
• The steel is also coated with rust retardants and anti-
corrosive paints to avoid rusting.
• Brick, sand or gravel is not utilised in the constructing
process; however, concrete is used only in the
foundation and in a three-inch deck flooring.
• Internal wall and false ceiling: LAGYP™ gypsum boards.
CONSTRUCTION:
• Around 80-90 per cent of the work was completed in
the factory under a controlled environment.
• In this system, different units of the building such as wall
panels, columns, etc, were produced within the factory
and then transported them to the actual site where 10-
20 per cent of the work was carried out by simply
installing them.
• Also, utility arrangements such as HVAC, plumbing,
electrical, fire-fighting, etc, were fitted in the floor
frames of steel.

• A lightweight structure with a unique
bracing system.
• Sustainable, non-toxic and recyclable.
• Reduced the amount of waste, carbon
footprint and the impact on green spaces
at the actual site.
• The structure is also energy-efficient as it
provides floor insulation using the HVAC
technique, the energy recovery
ventilator (ERV) system and electrostatic
precipitator system for fresh air circulation,
lux-controlled curtains for temperature
maintenance, occupancy sensor,
temperature sensor, remote control
switches and LEDs.

7. PROBLEMS FACED IN
CONVENTIONAL CONSTRUCTION
• Time Consuming
• Cost Escalations/variations
• Poor Quality Construction
• Shortage of Skilled
Manpower
• Time over runs
• Unsafe Buildings
ADVANTAGES:
• Energy efficient houses
• Safety at Construction
• Earth Quake resistance
• Faster construction mode saves time.
• No Cost escalations
• Less Electricity Consumption
• Early return on Investment.
• Quicker income from rental.
• Minimal material wastage and increased
asset value.
• Economy of scale in manufacturing
• Salvage Value after lifetime
• Availability of more carpet area
