The following diagrams show various measurements that I have made of my Titan in order to determine my pier height & observatory roof height as well as to help determine the location of the pier in an observatory. Perhaps they can be of use to someone?
The above image may not be of to much use but it shows you the size of the titan mount when compared to a 300mm (12") diameter cement pier. This size pier may be a bit of overkill for such a mount but I found it to me absolutely rock solid. It's better to over-engineer something than to under-engineer.
