FOCUS
all considering various soil interactions.
The design of the water supply system
proved to be a significant challenge, so the
team turned to Bentley software to help
determine the best and most economical
design.
Larsen & Toubro used an in-house
electronic document management
system (EDMS) to manage the five
disciplines involved in the drawings. The
documents were uploaded to the EDMS
database for verification by corresponding
section heads. The section heads of the
corresponding disciplines reviewed the
drawings and gave clearance that all of
the requirements were updated. After
clearance, the workflow was automatically
routed for interfacing to the respective
disciplines, then re-routed to the design
division head for final review.
Using OpenFlows WaterGEMS, the
engineering team rapidly designed
the network, putting them ahead of
schedule. With the help of STAAD.Pro,
the team was able to quickly design the
structural foundations for the treatment
facility, elevated storage tanks and other
structures, allowing the design work
to be completed 30% faster than they
would have using manual methods. They
used PLAXIS to secure the safety of the
work area, determining safe excavation
sloping and saving time and money. The
engineering design phase was ahead of
schedule, saving two precious months
due to digitalisation support from Bentley
applications, helping them to deliver the
project 25% faster.
WORKING SMARTER TO IMPROVE
THE HEALTH, EDUCATION AND
LIVELIHOOD OF PEOPLE IN THE
COMMUNITY
Enabling access to water for the community
and completing this project faster will have
enormous value for the local households,
food, culture, health, education, economics
as well as the integrity of the natural
environment. The project will enable
1.5 million people to achieve sustainable
health through quality drinking water. From
improving access to education to enabling
women to earn a wage instead of fetching
water, this social commitment is impacting
the quality of life in this area.
A key consideration in the engineering of
this project was that the treatment facility
had to fit within a very limited area. Larsen
& Toubro were sensitive and considerate in
keeping the sacred grounds of the nearby
temple untouched. Located directly in the
middle of the space to avoid upsetting the
local community, they found innovative
ways to connect pipelines around the
temple grounds. It is a testament to Larsen
& Toubro’s values, skills and caring culture
that they prided themselves on this attention
to detail.
The Indian government has long trusted
Larsen & Toubro and their sustainability
practices shine as evidence in their work
for economic, environmental and social
responsibility. As a builder of major
infrastructure projects in India, they are
constantly contributing to the quality of
life of the communities they impact. Their
team fosters continuous growth towards
ESG-related concerns such as climate
stewardship, green initiatives and the
circular economy with a dedication to reuse,
recycle, repair and refurbish as long as
possible.
WATER CONSERVANCY INITIATIVE
REDUCES ENVIRONMENTAL IMPACT
Located in the high-altitude alpine region of
Tibet, the PZ Dam is a hydro complex that
is part of a water conservancy initiative.
It is focused on irrigating 2,600 hectares
downstream and generating power to
help improve both urban and rural water
supply and the regional water ecological
environment. Knowing the importance of
subsurface findings, the survey and design
team faced challenging terrain, extreme
environmental conditions and a short
construction period.
Given the fragile ecological environment and
extreme cold, traditional survey methods
could not accommodate the investigation.
China Water Resources Beifang Investigation,
Design and Research explored digital data
acquisition and 3D modelling of geological
data but found that many software products
could not integrate and maximise data
potential.
Using Bentley’s ContextCapture, China
Water found they could more easily process
data for geological visibility. They also
deployed ProjectWise for multidiscipline
