Bentley's Haestad Methods Solutions Selected No. 1 Water Resources Modeling Software in National Survey

Bentley Systems, Incorporated today announced that its Haestad
Methods product line has been selected as the No. 1 water resources
modeling software in a national survey. The survey, commissioned by
Bentley, was conducted across the readership of CE News' Civil
Connection, a leading civil engineering newsletter published by
ZweigWhite. This follows on the heels of the People's Choice Award
that Bentley's WaterGEMS product in its Haestad line won at the
American Water Works Association Annual Conference and Exposition and
is being celebrated by Bentley through special limited-time
promotional offers.

The survey asked licensed civil engineering professionals employed
by leading consulting engineering, survey, and construction firms and
key public works departments, utilities, and municipalities about
their software preferences in seven categories of water resources
modeling software. Bentley's Haestad solutions earned the No. 1
position - receiving up to more than three times the top responses of
the closest competing products - in the following five categories:

-- Water distribution

-- Transient analysis

-- Wastewater conveyance

-- Stormwater networks

-- General hydraulics

In the detention pond category Intelisolve's product came in
first, and in the floodplain modeling category the Hydrologic
Engineering Center's (HEC's) product took the top position.

"It's gratifying to once again have users confirm Bentley's
technology and market leadership as well as the value of Haestad
Methods solutions in meeting their needs," said Charley Ferrucci, vice
president, Bentley water asset solutions.

Added Ferrucci, "Though this survey confirms our first-place
position among civil engineers, utilities, and municipalities only in
the United States, we are also establishing this same leadership
globally. Haestad Methods solutions are broadly available around the
world, including in some of the fastest-growing economies such as
China and India."

In the survey, Bentley's WaterCAD, WaterGEMS, HAMMER, SewerCAD,
and SewerGEMS products in its Haestad line received more than three
times the top responses of their closest competitors, among responses
from water utilities and municipalities in the water distribution,
transient analysis, and wastewater conveyance categories. Bentley's
StormCAD and CivilStorm topped the stormwater networks category, as
did its CulvertMaster and FlowMaster in the general hydraulics
category. Bentley's PondPack came in second in the detention pond
analysis category and its HEC-Pack came in third in the floodplain
modeling category.

The survey respondents also said that ease of use is their
foremost requirement for water resources modeling software, and that
they found Bentley's Haestad Methods products to be the easiest to
use. Said Ferrucci, "It comes as no surprise that ease of use is a top
priority. Hydraulic modeling is complex by nature and can consume a
great deal of an engineer's time. Our investment in usability improves
productivity in all three critical stages of the modeling process:
model building and setup, calibration, and results analysis. This
means our users can spend more time doing what they know best:
engineering."

Multiplatform interoperability across stand-alone, CAD, and GIS
platforms was second in the survey respondents' list of must-have
characteristics. When asked about their use of CAD, GIS, and
stand-alone platforms for water resources modeling, 77 percent said
they normally use at least two of these platforms simultaneously.

In explaining the critical importance of multiplatform
interoperability to water resources projects, Thomas Walski, senior
product manager for Bentley water products, said, "All of these
projects require collaboration among people from different disciplines
with preferences for different work environments.

"With our level of multiplatform interoperability, models work
together no matter what platform they were created in; people work
collaboratively, each in his or her preferred environment; and
organizations work more efficiently by leveraging the skills of their
specialists and their investments in technology. Moreover, there are
no translation errors to contend with."

Walski continued, "On the other hand, organizations that choose a
less interoperable platform are often forced to buy additional
licenses of ArcGIS or AutoCAD just to run the model, to train modeling
team members that are not familiar with the selected platform, and to
deal with translation errors that increase costs and hamper project
schedules."

To celebrate Haestad Methods solutions being selected as the No. 1
water resources modeling software, Bentley is offering, for a limited
time, a 20 percent license-fee discount on all of the "No. 1 products"
in its Haestad line. To learn more about this special promotion, visit
