Mill-reject Handling system – super thermal power plant
The 1x500 megawatt super thermal power plant under construction in the
state of West Bengal is owned by n Tpc, India’s largest power company. The
prime contractor, Bharat Heavy electricals, subcontracted United conveyor
corporation to design the mill-reject handling system. The system conveys
coal from the mills to the mill reject bunker. The elevated conveying lines were
restricted to a designated corridor.
All structural and piping design work was performed using Autopl An T and
proStructures. The software helped to economize the designs and detect
clashes, reducing construction costs and preventing time overruns on site.
Developing a coordinated 3D model, then generating 2D drawings, allowed
United conveyor to stay on schedule. The bills of material extracted from the
models helped United conveyor release material quantities on time.
Y&V Ingeniería y construcción developed the detailing for a 232 megawatt
power plant at a refinery located in the northeastern region of Venezuela. The
main obstacle was to set up the project within a relatively short time frame so
that isometrics and plans could be delivered on time. Autopl An T was used to
develop 3D models for piping and equipment, reducing the man-hours required
to draft plans and isometrics.

compared to 2D methods, Autopl An T reduced the time required for modeling
piping and extracting isometrics from 60 man-hours to 40 man-hours. Three-dimensional modeling of plant plans took eight man-hours vs. 80 man-hours
in 2D. And materials take-offs took four man-hours vs. 14 man-hours in 2D.
The margin of error in inventorying and materials checking was also reduced,
minimizing related costs.
