Description of Systems and Role of Project:

As part of a $71 million major renovation to this federal courthouse, secure parking was needed for judges and key staff. Completed in 1940, the historic Courthouse is a major example of the Federal Art Deco style, employing classic, simple elements and massing consistent with the design image of a United States Courthouse and the era in which it was designed. The building previously housed U.S. District Court, reopened after renovation as the new home for the Seattle office of the 9th U.S. Circuit Court of Appeals.

The solution to secure parking was to construct an invisible underground parking garage at the basement level (underneath the grass in the rendering). For security, its entrance is protected by an active vehicle barrier system with sophisticated hydraulics and integrated electronic controls provided by Justice Systems on a turnkey basis.

The coiling doors and bollard hydraulic pump units contained local controllers.  To seamlessly integrate these systems, JSC provided an independent stand alone programmable logic controller (PLC).  The PLC simultaneously controlled all devices for vehicle entry and exit without need for human intervention.


VEHICLE ENTRY:

Card Reader

Gate Arm

Traffic Light

Retractable Bollards

Roll-Up Door

Traffic-Loops


MAINTENANCE:  Because of the complexity of the system, JSC provided a GE QuickPanel to log all events while displaying the current state of all devices.  By providing instant diagnosis of each system element, this substantially reduced downtime.

VEHICLE EXIT:

Card Reader

Traffic Light

Retractable Bollard

Roll-up Door

Pedestrian Warning
