Articles and Insight

There are some questions I get almost every day and I never have good answers or even resources to find those answers.

Today our very own Mark Scacco emails me a list of articles he has written over the past year or so for industry magazines POB (  and Site Prep ( , and I found that each one of them hit the spot.  See links below to download your own copy of each article.

Volume words of warning

Tonites post is a result of some work I was doing the other day. I was trying out the brand new corridor volume tables. I was a little confused by some of my results so I thought I would pass along what I learned. Basically what happens is this: the volume table is dynamic all the time. What do I mean by that? Well my montage of images should paint the picture. If you have a corridor model that is not set to automatically rebuild(Like me because I can’t stand waiting all the time for rebuilds). Anyways on with the show.

In this first image you can see the corridor volumes and the model.

The second image shows the alignment having been moved, the out of date corridor in prospector and the new volume numbers. When I saw this some alarm bells went off in my head, the corridor isnt rebuilt but the volume table is showing new numbers, wrong numbers! What I was able to deduce is when we move the alignment the sample lines move with it, and update based on their new postion within the corridor surface. The problem is the corridor needs to be rebuilt. Now those folks in manchester do have the event viewer pop up and warn us with the message that the corridor is out of date, but I got a little tired of the event viewer myself and set mine not to pop up so I missed out on the warning.

Last screen shot. In this one you can see the volumes have changed again, the corridor has been rebuilt. Everything is back to being correct. So what was the point of all this rambling? Make sure you rebuild your corridor while making volume edits.
