This site near Buffalo, New York required a special room with a "high-hat" design to allow enough clearance for the current probe. Additionally, the soil conditions were such that the site required four pilings to be sunk to hold the weight of the magnet.

Since these pilings were to be drilled and installed inside an existing building, a special rig was assembled in the space at considerable time and expense.

All the while this work was underway, the magnet, an Oxford OR30, sat outside in the parking lot.

A group of people, including the MRI owner's engineer and the general contractor measured and marked "iso-center" in the room. The contractor proceeded to drill and place the pilings and then build up the scan room. And he never checked the measurements.

Here's the result after the magnet was placed on the pilings.
