The Portland Bureau of Transportation (PBOT) manages transportation assets with a replacement value of $8 billion. Paved streets, the sidewalk system, bridges, traffic signals (signal hardware), and streetlights make up the majority of the dollar value ($8 billion). In addition to these key assets, the City of Portland owns other assets that ensure the safety and movement of people and goods: streetcars, an aerial tram, various support facilities, traffic calming devices, signs, parking meters, parking garages, pavement markings, bikeways, guardrails, retaining walls, the Harbor Wall, stairways, and traffic signal computer controllers.
Asset Management Approach
Transportation utilizes asset management as a way to effectively and efficiently allocate resources, measure performance, and track infrastructure needs. PBOT’s Asset Management Advisory Committee (which includes engineers and operations staff as well as maintenance, finance, and information technology managers) sets the priorities for asset management within the bureau and helps implement those priorities into business practices.
Asset Management Achievements
The new Pavement Management System (PMS) enables reporting on condition of streets based upon a new visual inspection methodology. With this new system, Transportation can determine maintenance timing and needs on all arterial, collector and local streets that Transportation owns and maintains. The new PMS will help the Portland Bureau of Transportation effectively and efficiently prioritize the allocation of revenue to address pavement needs.
Transportation currently conducts condition monitoring on pavement, bridges, structures, street lights, and traffic signal infrastructure. PBOT is working with engineers and technology staff to expand condition monitoring to guardrail and warning and regulatory signs. Condition monitoring will allow PBOT to plan for appropriate preventive maintenance, rehabilitation or replacement needs and budget accordingly.
PBOT is in the process of conducting a risk assessment for failure of assets. Criteria for assessing consequences and likelihood of failure have been created and are being applied to transportation assets. A risk registry, identifying failure modes and assigning risk of failure, will be created.
