Long-term storage ring and experiment hall floor settlements are being monitored on a regular bases in six-month intervals utilizing common geometric leveling techniques. One area of concern requiring special attention in terms of settlements is the vehicle tunnel that undercuts the experiment hall an storage ring at the south side of the APS. Five user beamlines crossing over the vehicle tunnel could be affected by deformations in this area. Assuming the most severe temperature fluctuations would occur during the winter time, a monitoring system was installed at the beginning of 1996. The length of the experiment was dictated by the installation schedule of the user enclosures at the overpass
