At the start of the project, the team completed surveys of each building to determine existing condition of elevator equipment, affected building areas, and hoistway construction. A report documented findings and made recommendations for what equipment needed to be replaced, what components could be refurbished, and the adequacy of the current power supply. JDBA was responsible for coordination of the total design, architectural services, construction documentation, construction administration, managing the consultant team, and coordination with County representatives.
 
The project included new elevator equipment and controls as well as architectural, mechanical, electrical and structural engineering renovations necessary to accommodate the upgrades, including design of accessibility modifications. Each building included four public elevators, separate secure elevators for staff and judges, and secure custody elevators connecting the detention area and courtrooms.
 
As part of a value engineering effort, some major components were able to be refurbished, including hoist machines. In addition to replacing equipment with heavy-duty or high-speed components, new equipment provided energy savings with high-efficiency.
 
At both buildings, penthouse machine rooms were modified with increased ventilation (Pomona) or air conditioning (Norwalk) to provide optimized temperature and humidity for mechanical equipment to operate at peak efficiency and last for their intended life cycle.
