E.3 Maintenance

E.3 – Maintenance
Common Maintenance Practices

Most DOT equipment and many transportation assets have well documented standards for routine and preventative maintenance. Equipment manufacturers recommend regular preventive maintenance cycles (for example oil changes or tune-ups) and many DOTs, other transportation asset owners, or industry representatives have recommendations for when various transportation assets should be inspected or receive preventive care.

These practices can be incorporated into DOT life-cycle models and maintenance programs. By investing in these activities, even on a defined, interval-based methodology, the DOT can expect to generate long term savings through improved performance and extended service life.

Automated Work Ordering

Where asset management and work ordering systems can be integrated, implement tools to automatically screen the asset inventory for routine, preventive, and reactive maintenance candidates. When assets are identified, automatically generate and assign work orders to trigger necessary maintenance activities.

Important Terminology

The following terms are used within this Section.

Automated Work Ordering:

An automated process that generates maintenance work orders, typically based on asset use, age, maintenance or work logs, inspection results, observed defects, or condition ratings.

Preventive Maintenance:

Programs or activities employing network level, long-term strategy that enhances asset performance or extends asset life through a set of proactive, cost-effective practices.

Routine Maintenance:

Routine maintenance are maintenance tasks that are planned in advance. These can be recurring or one-off scheduled preventative care.

Conceptual Examples
Promoting Awareness
Standard Operating Procedures

Identify targeted routine and preventive maintenance activities and document clear standard operating procedures for maintenance staff.  Share this documentation in an easily accessible location and advertise its availability.  For complex activities, consider establishing formal training courses to ensure proper application.

Targeted Communication and Outreach

Organize regular meetings with field maintainers and promote preventive and routine maintenance expectations and opportunities.  Share anticipated outcomes and benefits to the agency.

Performance Targets

Using life-cycle modeling, interval-based methods, or available funding, establish and track preventive maintenance targets.  Validate that maintenance is being targeted to appropriate candidates (as preventive maintenance is typically only useful to extend the life of an asset that is still in good condition).
