OK, thanks for the enquiry. Hope they are enjoying and producing some great visualizations with their Lumion v6 product. By colleagues, do I gather you are therefore in the IT side of the organisation?
You will see at the forum a good number of questions about suitable hardware for Lumion. Some are in the Guest Sections, the rest in the section for Licensed user members. You are welcome to register one of your colleagues licenses' to gain access to those extra resources, it does not have to be the user only.
Anyway, in reply to your query:

The SketchUp model size and indication of scenes suggests the team are working with Very Complex to Ultra Complex Scenes as mentioned in this article: Which graphics card do you need?
As most of the rendering and onscreen work is done by the graphics card, we would generally suggest looking at 'gaming' based PC's. The reason is simple, they tend to be better optimised for the leading edge graphics rendering that Lumion does. Xeon/Quadro based hardware is 'workstation' based with cards for CAD/vector based environments.
Either can perform much the same as the other, and we do have many members with Quadro based PC's, including M5000 and some with M6000's. A main difference is in the cost point in both the Xeon CPU's compared to i7's, and in the graphics cards Quadro compared to GTX. For example, a NVIDIA Quadro M6000 has a Passmark of 10271 with price US$4999. Compare that to a GeForce GTX TITAN X (as it has the same memory of 12GB) 10850 for US$1,470, or the GeForce GTX 980Ti at 11607 price US$600 (6GB).
Xeons are also have a similar price difference.
You might also want to compare the i7-5960X for any advantage over the i7-5930k.
If the hardware will be sharing work with other CAD, then you may find that (excluding cost) that the Quadro is the way to go. If it's mainly to create and render Lumion scenes, then it seems reasonable that you only need to look at the GTX cards. That said, we also have members who find the GTX works equally well with their CAD software.
The rest of the specifications on either option look fine with 32GB of RAM and a good sized SSD drive.
For the meantime, please make sure Windows 7 (64 bit version) is installed on the PC or PC's: refer our Knowledge Base Article
: Why do you recommend Windows 7 instead of Windows 8 & 10?
Graphic Card : 2X GTX 980 Ti SLI
Lumion is not able to use 2 cards in SLI, so the second one would only be useful if there are two monitors and the user runs other applications off one card to one monitor, and Lumion off the other card to the other monitor.
and renting an online server to perform rendering.
One of the advantages of Lumion is that it does not require render farms
Hope that gives you some pointers to work with, and does not confuse the choice of options (too much
