Editorial

John Trotti

From our very first issue, we’ve trumpeted the themes of (1) employee welfare and training, (2) attention to safety, (3) regulatory compliance, and (4) adoption of proven technologies as the foundations for success. These have the basis for the vast majority of our articles and the subject of nearly all my Editor’s Comments over the years. And here we are again.

The cover shot and the article that goes with it (“Size Doesn’t Matter,”) offer proof that the magazine has been spot-on from its very first issue when we turned our focus on technologies with the article titled “Automating Your Construction Site” (www.gradingandexcavating.com/gec_9909_automate.html), which at that moment seemed more in the realm of Buck Rogers than your everyday dirt-moving world. The fact that GPS and lasers existed in the rarified atmospheres of the mining industry or the very largest construction firms, and then only on their most expensive machinery, may have made our prophecy look pretty far-fetched back then, but not anymore. While these tools might not be in everyone’s rollaway yet, it’s apparent that it’s just a matter of time before they are.

A Peek at the Past
Let me take you back to ConExpo 1999 where for the most part the machines were hydro-mechanical and the displays, while digitally based, parroted their analog ancestors. Yes, laser and GPS systems were present, but not on the front line. For the most part it seemed like its predecessor with only a trim and a rinse to mark the three-year passage of time.

ConExpo 2002, by contrast, was a wake-up call to the 100,000-plus visitors who trooped the area in a state of amazement at the tremendous display of technological wizardry. While in some ways it smacked of “things to come,” it showed for certain that the days of beefy levers and no-nonsense dials were numbered, booted out to pasture by fighter plane joysticks and electronic display panels offering the promise of control and information beyond imagination.

It remained for this year’s ConExpo to drive home the point that the electronic-hydraulic onslaught was no flash-in-the-pan. A revolution was in full progress, leaving the questions not of if and what, but rather of how far and how fast … and that’s the threshold we stand at today.

What’s in Store for Us?
The opportunities afforded by existing technologies are too great to envision, much less enumerate, but I’d like to suggest one to consider.

Over the past several years we’ve experienced an increase in the amount of night and inclement weather work, both of which place a premium on situational awareness. During this same period we’ve witnessed a significant increase in the use of hearing protection gear—plugs, Mickey Mouse ears, or acoustic earphones—and while there is much to be said for the health aspects involved, the isolation from the immediate environment introduces dangers of a different sort to work sites. OK, we’ve got a situational awareness problem.

What do we do about it?

The best answer, of course, is to provide constant reminders of these risks to our workers at daily meetings, at lunchbox training presentations, through signage, and by other attention-getters, but I wonder if this isn’t an opportunity to bring some existing technologies to bear.

While still in its infancy, military commanders now have the ability to monitor the precise position not only of aircraft and vehicles, but also of individual soldiers … and then direct their activities via discrete communications. Granted, this requires some very sophisticated and expensive stuff, such as the use of satellite sensors, transmitters, and transponders, but then we don’t need all the bells and whistles to monitor and control a job site. In fact, the basic tools already exist in the commercial world, and there’s a good chance you employ many of them right now.

If you are using a GPS (or laser) base station and can communicate with your people and equipment in real time, you are well on the way to having what amounts to a job-site collision avoidance system. What’s missing is the black box that integrates location data, looks for potential collisions, and issues some sort of warning or command.

It’s truly astounding what technology makes possible these days. It seems that our biggest problem lies in deciding what we want and then asking for it.
