Larsen & Toubro India executed a gas-based combined-cycle power plant near
Rajahmundry in India. The power block includes gas turbine generators, triple-pressure reheat heat recovery steam generators, and steam turbine generators.
Challenges were to deliver engineering outputs in a compressed time schedule
and integrate work across locations.
Larsen & Toubro built to-scale and realistic images of the heat recovery steam
generators, developed a 3D model at two different locations, and improved
team and design review communications. The project team used AutoPLANT
to detail most components and ensure that layouts were free of interference,
and shared the 3D model with the project site to facilitate site construction and

Gas-Based Power Plant Model
For this gas-based power plant model, L&T-Sargent & Lundy’s goal was to
execute the project within an aggressive schedule and ensure error-free design.
The project team was to complete the design and detailed engineering of the
open-cycle power plant within four months while maintaining the accuracy
and quality of the deliverables. To meet such an aggressive schedule, all
departments had to work simultaneously.
By using MicroStation and Bentley Navigator, the project team developed a
complete 3D model of layouts and delivered documents within the stipulated
time frame. They also made all deliverables error-free, thereby reducing the need
for additional man-hours. It would have been difficult, if not impossible, to generate
clash-free design without using the 3D model platform and Bentley Navigator.
