We upgrade every other year as a general year unless the newest version has something of major interest to us over the current year. Once you are on subscription, you can download the newest version when it comes out.

Type I trucks are what you would typically see at a commercial / residential fire. A large wildland or brush unit would be a type III. The engines are not what will be your most difficult design criteria however. A lot of wildland water tenders are built on larger chassis with all axles being...

Several manufacturers have engineered units specifically for these applications. By the time you figure out the maintenance (cleaning as needed and required by the town), installation, and other costs; getting a unit designed specifically for the purpose is generally a lot cheaper and easier...

I would look more towards a move within your company. Obviously, you are not happy in the "clerical" side of procurement, but you state that the company does much more than that. See if you can transfer to another department. Even if it is just for a particular contract, the experience will...

We are working on a project that is 3 miles long. We have full survey and design done. Parts of this project are being done by 4 different companies and everyone is sharing their work. Our problem is that our drawing has 4 dgn references and 4 dwg references. It is a little over 28Mb now...

I also would highly recommend the "tar and chip" sealing. Even if the base is concrete stabilized, there still may be pockets that do not get fully stabilized leading to potholes, erosion, and then a worse road than you have now. If the big worry is erosion, I would concentrate on sealing the...

If you want to intercept the water, place the trench drain at the lowest point (along the contours) to minimize ponding. If you are going into a structure, then it makes sense to have the drain perpendicular to the driveway as it enters the garage.

I am modeling a roadway through mountainous terrain in civil 3d. In doing so, I have created the alignment, profile, corridor, and corridor surface. I set the target of the corridor and surface as the existing surface. The corridor surface itself looks good. When I do a drive, the existing...

2" is about the thickest that I have seen 9.5 used successfully. It does seal a little better than the 12.5, but with that thickness, there may be more issues with rutting. I personally would stick with the 12.5 if it is going to be a 2" lift. If they want to do a 12.5 scratch with 9.5...

If you talk to ACO, Zurn, Watts, or ABT, any of them would be happy to provide you with a spec on a trench drain that will meet your needs as you describe. The problem with 112.6.3 is that it was written around floor drains and the loading parameters are not condusive for testing long, narrow...

What will be the loading, flow rate, ground slope, and required slope? Will there be anything other than rain water going into the drain (oil water separator, chemical concerns)?

We are working in 2013 Civil 3D. The client has 2011. When I am saving the drawing back to 2010 version, it gives me an error stating that the 3D components will not transfer and will be proxy images. This means that I am losing my alignments, surfaces, profiles, and sections. Exporting a...
