Challenges in leveraging engineering knowledge"
It all starts with capture – but how is it done today?

•  Lack of standardized process and tools
to capture calculations and IP
–  Multiple tools and mediums for data
discovery and analysis
–  Information is stored in multiple sources
and locations
–  Limited support for traceability

•  Limited sharing and reuse of
calculations and IP
–  Tedious process to search, compile and
understanding how to apply the knowledge
•  Easier to ‘reinvent the wheel’ for new projects

–  Significant time to bring new resources
‘up to speed’

Business implications"
How does this scenario impact your business?

•  Loss of IP (due to attrition)
–  Delays in getting new engineers fully up-to-speed and productive on design
best practices

•  Delayed and over-budget projects
–  Wasted time spent fixing calculation errors late in the design cycle or after
product launch

•  Lost market share and revenue
–  Calculation errors force product recalls or costly rebuilds
–  Not re-using corporate IP forces delays in time-to-market

•  Inability to support and demonstrate compliance
–  Critical corporate IP stored in multiple systems must be manually assembled
for submission to regulatory bodies

•  Higher costs due to prototypes and lost productivity
–  Optimized designs from earlier products lost and not re-used
–  Engineers spend unnecessary time ‘re-discovering’ critical corporate IP

build up more rapidly than you might expect.’!

Uni-Systems scores big in designing  
retractable stadium roofs using Mathcad"
In the late 1960’s, Uni-Systems, LLC was established to develop moveable structures for aerospace
giants such as Boeing Aircraft, American Airlines, and Cape Canaveral Air Force Station. Later, the
company branched into the military, construction, entertainment, and, in more recent years, sports
industries. Uni-Systems has designed, fabricated and installed the mechanization components for
five of the last six retractable sports-stadium roofs built in North America
The challenge
Design and build the first fully retractable, natural-grass playing surface in the United States. Uni-Systems’ design team
needed to devise a way to move an 18.9 million-pound playing field in and out of the stadium at the touch of a button
The solution
Unlike proprietary calculating tools and spreadsheets, Mathcad enables
engineers to design and document engineering calculations simultaneously, with
comprehensive applied math functionality and dynamic, unit-aware calculations.
Even better, Uni-Systems encountered very little downtime getting up to speed
using Mathcad. And, throughout the design process, the Uni-Systems team kept
all calculations in Mathcad, resulting in easy-to-see – and share – calculations.
The result(s)
BusinessWeek magazine voted University of Phoenix Stadium one of the
‘Top 10’ sports facilities in the world, and in 2007 the Arizona Republic
named it one of the seven wonders of Arizona.

Accurate engineering calculations are critical  
for bridge design at SAMHYUN PF (Korea)"
SAMHYUN PF (Korea) is a bridge construction company established in 1999. SAMHYUN has since
become a leader in ‘preflex’ bridge construction, with the experience and knowledge in all aspects of
the business- from design to construction. Recently, SAMHYUN led the industry with the successful
development of the ‘Precom’ girder technique- the latest composite method of bridge construction.
Previous product used/evaluated
Microsoft Excel Spreadsheets

Business initiative
SAMHYUN PF uses Mathcad as a calculation verification tool for the girder calculation process. Mathcad is critical for
its speed and minimal errors produced when creating the calculations behind these structures

The solution
The engineers at SAMHYUN PF create their key engineering calculations with Mathcad, so that they document their
calculations with ease and with less time then previously done in Excel

Result(s)
§  With Mathcad, SAMHYUN has achieved better verification of
calculations; Excel calculations often contained errors which could
not be checked easily
§  With Mathcad, SAMHYUN’s engineers have saved over 50% of
their time in creating calculations- allowing for their easy
documentation and re-use
§  SAMHYUN has been able to create an automated calculation
system for ‘Precom’ using Mathcad
