The Future is Virtually Here

Posted February 05, 2009 8:08 AM

If you'd told my dad ten or twenty years ago that running a successful construction project from groundbreaking, to HVAC installation, to project close-out would be largely dependent not upon the talent of project managers or technicians, but computer "tracking" software, he might have told you to "take another sip."

But the fact remains, we are living "in the age of virtual construction." Much of the estimating, buying, installation, project management, balancing and component controlling is handled in real-time via computers and sophisticated computer tracking software. While computers have been promising to make HVAC engineering and contracting methods more efficient for more than two decades now, it's only been recently that soft and hardware has evolved into the highly trusted tool of the trade.

And virtual efficiency should, in theory anyway, mean significant cost savings for HVAC contractors who have come to rely on the transfer of real-time field data to their shops which might be a dozen miles away or even a couple of thousands of miles away.

But like anything else in this business, going "virtual" requires constant education and it requires never ending patience. It also requires a sort of blind trust in a technology that, despite our computer dominated times, might still seem foreign to old timers like my dad.

As an mechanical engineer or contractor, have you made the introduction of real-time or virtual construction software a priority for your business? Or, despite the trend, do you still favor the more traditional "man power" approach to everything from work acquisition to tracking equipment and components? Do you favor a more balanced approach between man and computer? Or, do you foresee a future in which one or two people can orchestrate a major HVAC project taking place half way around the world simply by relying on continually evolving sophisticated computer tracking software?

The preceding article is a "sneak peek" from HVAC, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to HVAC today.

Computer tools are a god-send to virtually any endeavor, especially when it comes to organizing and presenting data. However, information has REAL value only when it crosses the human interface- when someone uses it to make a decision. Furthermore, no data system is ever going to replace the eyes of the man on site in determining the reality on the ground...

Computer generated projections are only as good as the programmers postulations.

I have experienced that a faulty human process, made electronic and automatic, is still a faulty process.

I laud the power of the computer to simplify the good processes, and speed up the compilation of data for decision making, however good sense is a strictly human trait. Deciding in advance what action will result from a certain set of data points has it's drawback in that other factors may vary rendering that action faulty.

I believe the most favorable results appear when an experienced human is assisted by the speed and accuracy of electronics which must be monitored to insure the parameters are up to date. Construction requires co-ordination and for-sight, and almost always requires adjustments to the original plans in response to the realities encountered.

I would offer that a computer generated or 'engineer at his desk only' plan has never been completely unchanged when put into practical application. I realize that 'never' is a pretty big word, but I used it specifically for it's meaning.

Yet I remain ever "ready to believe". CJM

I welcome advances in technology and I am sure more and more tasks will be handled by software in the future. I also realize that there will still be a place for the "old timers". Just as long after computer diagnostics for cars were available a mechanic was recommended to me by my grandfather who would simply place a broomstick to the engine and his ear. He was actually more accurate at diagnosing correctly the first time than the computers were and he was a lot less expensive. The irony lies in the fact that in another 10 or 20 years the current and near future technology will be so obsolete that the people that use it will become the "old timers".
