POLYHOUSE
● Alternate technique in agriculture which reduces
dependency on rainfall.
● Makes optimum use of land & water resources by
controlling temperature, humidity & ventilation of
air using equipments

3. 3
Our Project includes...
● Setting up a polyhouse in given area.
● Setting up the required equipments & controllers
suiting the crops to be cultivated.
● Training the farmers in using the equipments.

OUR CASE STUDY

5. 5
TRIPLE CONSTRAINT
Every project is constrained in different ways
by-
● SCOPE
● TIME
● COST
These limitations in project management are known as
triple constraint.

6. 6
SCOPE
● Development of one detached & fully controlled
polyhouse over 1 acre of land area.
● Sawtooth shaped polyhouse with nylon net walls &
polythene film roofs.
● South-north direction polyhouse.
● It will be installed with :
– Fans
– Cooling pads
– Heater systems

7. 7
● Irrigation Type:
– Fogging System
– Sprinklers
● Scope limits only to
– constuction of the polyhouse
– training to use the equipments installed

8. 8
COST
● The rough estimate of the budget can be given as
follows...
