Pipe Ovality: Better Ovality for Lower Costs

Pick a number from 1 to 10. What are the chances you would be able to choose the correct number? Only 10%, right? What if an inaccurate answer might cost you thousands if not hundreds of thousands dollars?

Pipe Defect Locations ... Suppose I'm Off?

I'm 100% confident this is the exact location to dig....I think." How often does this happen when making the decision of where to excavate and uncover pipe and point repair defects? In many cases, it may require multiple locations and excavations before the correct location is discovered. This can dramatically increase the cost of point repairs due to varying pavement types, obstructions and or other utility replacement or relocations. Typically, the location to excavate is primarily taken from CCTV footages and may or may not be as accurate as you think. . . . Read More

Mulit-Frequency Sonar: Fine Tuning Your Pipe Inspection System

Do you remember back to the days when the "rabbit ears" antennas were used to get a TV channel? You had to adjust the knob to get a good signal -- otherwise you were watching "snow" and then you had to keep adjusting the knob when the wind blew or it was raining to get just the right location and picture? Even worse, it was before the remote control age, so you had to keep getting up and down to adjust it. We've come a long way since then for TV -- and for pipes, too. . . . Read More

Minimizing Sinkhole Damage: Where are the Voids?

That news story is usually accompanied by a picture of a massive sinkhole causing catastrophic damage. How did that sinkhole just happened to cave in? It was probably in the making for quite some time. Typically, sinkholes start with a small void that gradually increases into a cavern that eventually collapses the sewer and surrounding area and utilities.

GIS and Shared Inspection Data

How often do you schedule a company meeting without access to a company-wide, shared calendar? We all go through that exercise, and learn that we have no idea who is doing what, and when they are doing it. And how often do we start the meeting, only to learn that someone else was working on that same problem last week?

2D vs 3D Lasers in Large Pipes

We have all watched movies at home and at the cinema. Watching the same movie at home vs. the cinema can have a remarkably different effect, as the movie theater provides an enhanced sense of you actually "being there". Take that a step further with one of those enormous screen 3D IMAX theater experiences and you will actually feel like you are *in* the movie. This comparison leads us into this month's newsletter topic about 2D vs. 3D lasers. As you read, remember that a 2D laser is like watching a movie on TV, and a 3D Laser is like watching it on IMAX. . . . Read More
