The 3D model will allow the company to fully

The Torre Valdaliga Nord project in Italy will
transform a traditional heavy-oil-fed power station
running four 660-megawatt electrical capacity
units into a low-pollution, coal-fed power station
running three 660-megawatt electrical capacity
units. Capital expenditure for the project is around
$1.7 billion. Major revamping activities included
complete replacement of the boilers, an almost
complete replacement of the power generation
islands, and work on some external areas, including the neighboring harbor facility since the coal
will arrive by ship.
Several design review sessions have been done
with the plant's owner, Enel GEM, and major
The biggest advantages provided by the use of
Bentley technologies lie in the correctness of the
design and the ability to have all of the plant
data, both 2D and 3D, stored in a unique and
consistent database. This dramatically reduces, if
not eliminates, design errors. In addition, the 3D

Hallsdalle-Powell Utilities District—Norris Lake Water Treatment Plant
Jordan, Jones & Goulding, Inc.
Jordan, Jones & Goulding, Inc. (JJG) was chosen
by Hallsdale-Powell Utility District to design the
$20-million Norris Lake Water Treatment Plant.
The plant in Tennessee will have a rated capacity
of four million gallons per day (mgd), with provisions for expansion to eight mgd and four additional treatment trains. The project includes a new
raw water pump station/intake structure, treatment building, clearwell, lagoons for solids handling, and an on-site sodium hypochlorite generation system.
The design team used Bentley AutoPLANT software to produce intelligent process and instrumentation diagrams (P&IDs) and 3D computer
models of the new treatment building as well as
other facilities. By preparing, intelligent P&IDs
using the external database, the firm could compare the 2D elements to the components found in
the 3D models, reducing errors and omissions.
Using Bentley Explorer interference detection
tools, JJG identified problems and decreased the
potential for RFIs during the construction phase.
The tools made it easy to tell what changes have
been made, what new conflicts have arisen,
where components live in relation to each other,
and what the entire plant will eventually look like
inside and out from every angle.
In addition, the model has been exported
to an animation format and handed off to the construction management team and constructor. ;
