After being rescued from the Blood Harvest you find the driver of your rescue vehicle has become infected, and has crashed behind a massive asylum. The Trans-Allegheny Lunatic Asylum.
The "Forensic building". I have also seen it called the prison building and Criminally insane building.

Top notch as always
How do you get the correct height?
SketchUp has two features to match buildings:
One: Importing a image from Google Earth. This gives you the footprint of the building at 1:1 scale. You draw the outline and extrude that upwards to some unknown height.
Two: Photo matching, since you now have the outline you can find a point of reference on a photo and match that to a point on the model. In most cases I choose the corner of the building at ground level.
You adjust the photo as needed until the width of the building in the photo matches the width of your building model. Since the width is correct in the photo, the height is now correct. You then pull the height of the model downwards to match the photo.
There are video tutorials from google on how to do this, they are linked directly inside of SketchUp help.
Ah thanks, but 1 more question, I made a small mall in sketchup and I have a box around it but when I Export it as .vmf is says that "hammertime warning: Orphaned faces. Groups those guys!" but all the polygons are connected
There is too much to explain here. The simple answer is that all VMF object has to be grouping of faces making up a solid convex shape.
Read the Valve developer wiki on valid VMF shapes and see this thread here: Forums.steampowered.com
