Why trees or it’s branches are cut by us?

Safety of the public is paramount to us Godrejites.Trees in contact with power lines are a safety hazard,

with the potential for causing injury or even death by electrocution if someone touches a tree made ‘live’ by a power line.

Trees in windy or stormy conditions can cause power cuts. Power supply may be disrupted when trees or branches break thereby damaging poles, power lines or other structures.

Continued… Similarly, when conditions are dry, trees near power lines

can cause serious fires.These are the danger of trees near power lines.

Growth Limit Zone:The tree in this illustration will

need to be cut or trimmed because it encroaches the Growth Limit Zone.

The Growth Limit Zone (GLZ) is the minimum space surrounding any powerline that must be kept clear of trees and other vegetation. The size of this zone depends on the voltage of the power lines.

The Notice Zone:The Notice Zone (NOTZ) extends one metre beyond the

Growth Limit Zone. Should a tree encroach the Notice Zone, we may send a 'Hazard Warning Notice' advising you that the tree must not encroach the GLZ.

For Powerline spans up to 150 meters VOLTAGE GROWTH LIMIT ZONE

Problems caused by cutting or trimming trees:

Adverse impact on:1. Atmosphere2. Biodiversity3. Economical impact, etc. Most pressure will come from the world's developing

countries, which have the fastest-growing populations and most rapid economic (industrial) growth.

Why this Kaizen?In our work, while erecting poles, sometimes it is seen

that a tree or it’s branch come in the way of our erection activity.

After taking all the requisite permissions, the tree or it’s branches are trimmed off so that the line is laid and the work is carried forward without any difficulties or hindrances.

Hence, we see that cutting or trimming of trees in INEVITABLE. Therefore we have come out with this kaizen.

What can be done?All such events where we are required to cut or trim the

trees are to be noted by the site engineer in charge.Proper documentation of such activities should be done.For every tree affected (be it’s branch or the tree as a

whole), idea is to plant at least two saplings that would not only serve as a compensation but also work as an initiative towards the conservation of our mother nature.

Excel sheet for Documentation:

Tree plantation & Godrej :In face of ever increasing urbanization, Godrej has always

been alive to environmental concerns. It is our intention to give back as much, if not more, as is

being taken through the rigorous development process. At our Godrej, environmental consciousness is all pervasive.

So such initiative is only going to add to our CSR activity in environmental preservation.

Godrej strongly believes that green environment enhances productivity and quality.

So, continuing this noble ideology of our company, We, the site engineers, too, can contribute.

After effects of Kaizen:After proper documentation of tree trimming activities at

site, the tree plantation can be done on quarterly basis. Plantation of saplings can be done along the roads,

empty places in the Jabalpur city area taking care that the saplings would get ample amount of water, sunlight.

The whole concept is to ensure that the situation is improved upon from it's condition prior to trimming trees hence maintaining the ecological balance.
