The Corporate Center Building (CHUBB) in San Juan, which is an 8-story building that houses office space for 17 businesses in total. The Puerto Rico Trench, north of the island, is an undersea fault zone. As the North American plate slides under the Caribbean plate there -- at a rate of about 2 cm per year, according to the USGS -- it creates the potential for earthquakes and undersea landslides.

As there have been notable earthquakes/aftershocks in Puerto Rico, particularly in recent years, Dorado Services were concerned that were an earthquake with a higher magnitude to strike, employees in the CHUBB building would have to evacuate the building for it to be surveyed before it could be reoccupied. They appreciated that the inconvenience and loss of revenue due to a potentially unnecessary evacuation could be avoided if their building were monitored. Furthermore, as a GeoSIG Partner, they wanted to experience the Structural Health Monitoring Solution they offer firsthand, as well as use it as a demonstration building for the many interested people on the island.
Dorado Services of Puerto Rico installed a customised SHRM solution consisting of six AC-7X accelerometers in the main office building, four AC-7X accelerometers in the parking garage structure, and two GMSplusD digital seismic recorders used to record and store data from the accelerometers. Additionally, a relay card has been installed to activate emergency risk indicator lights across all floors to notify building occupants of the status of an event, with red indicating a high risk level and green indicating low risk level and no need to evacuate.
As Dorado Services have installed and commissioned the solution in their building, they can have full confidence in supporting any new installation they may make on the island. Additionally, they felt the reduction in their insurance premium was further incentive to carry out such a project.
Another solution using GeoSIG instruments and a capable partner showing that quality and reliability can also be cost effective.
