Agenda How did we get here? What have we done? Where are we going? Rigid Rugged Resilient

How did we get here?

First developed in 1989 Rigid Rugged Resilient Combination of SGH, FWHA, and ACPA Rigid Rugged Resilient

Fortran on DOS platform Very linear as was the custom for DOS programs, this is not a knock, we all basically had to program DOS in this manner, event driven architecture was difficult to do in DOS, unless you purchased an expensive platform that sat on top of DOS, and then we got Windows, which was originally a relatively inexpensive platform that set on top of DOS Rigid Rugged Resilient

Introduction of Windows Platform Big differences, more graphical, event driven, program was converted to VB for Windows (which is what I refer to as VB6), worked well for earlier versions of Windows (XP, for example), I have a computer at my office that is XP so I can work on VB6 programs for long time clients, unfortunately VB6 is no longer updated or supported by Microsoft, and as a results of that users were having trouble using PipeCar on modern operating systems, plus it is tough to find VB6 programmers, why the change? Rigid Rugged Resilient

Internet Revolution Now we have the Internet, this necessitated a new paradigm for software development, Microsoft introduced .NET platform, program development is much more complex today (glorified text editor for DOS to a complex development environment in .NET), also the interface is much larger part of programming than before (use example of percentages of interface design vs. engineering algorithms), so that’s when we came to an agreement with ACPA to take over PipeCar development Rigid Rugged Resilient

What have we done?

Changed name to Eriksson Pipe Rigid Rugged Resilient

Changed name to Eriksson Pipe And that’s it Rigid Rugged Resilient

Changed name to Eriksson Pipe And that’s it (just kidding) Rigid Rugged Resilient

Converted to VB.NET Rigid Rugged Resilient Brought code base forward to latest development environment (.NET), did not convert to C# (really no need to, as all .NET compliant languages are very similar) Rigid Rugged Resilient

Modernized the interface Allow both linear and event driven approach (will show in our live demo), but kept the familiar PipeCar dialog boxes, similar to ETCulvert, generation 2 of our interface paradigm, remember that interface design is a very large part of a Windows program, we are trying to reduce that, our current approach in Eriksson Culvert is generation 3, and we are already working on generation 4, where we are combining the text report and input (eliminating dialog boxes – actually did that in generation 3, reducing the learning curve – only one interface to learn instead of 2) Rigid Rugged Resilient

Expanded the documentation Updated user manual and help file, added QC manual, discuss QC problems (both published and unpublished) and how we run all of them before every release Rigid Rugged Resilient

Fixed lingering problems Some of these problems have been around for years (none of them were serious), we take calculation errors very seriously and we generally fix them within a week Rigid Rugged Resilient

Added Features Rigid Rugged Resilient Major ones were the support for 7th and ‘8th’ editions of LRFD, also have gone to subscription based (as has a lot of software these days), automated tech support option, we will cover other additions in our live demo Rigid Rugged Resilient

Where are we going?

Future of Eriksson Pipe Keep up with specification changes CANDE replacement? Pipe Jacking? Internal pressure? Future of Eriksson Software Spring chicken story Rigid Rugged Resilient
