Returning Metro’s Assets to a State of Good Repair

January 3rd, 2017 No comments

Metro needs over $17B in the next ten years to reach and maintain the State of Good Repair (SGR), which accounts for approximately 70% of its total needs over the same period.

As noted in our our previous post, Metro’s SGR needs are built off of a comprehensive inventory of existing assets as a part of the Capital Needs Inventory (CNI). Each record in this inventory documents the asset’s type, age, expected life, replacement cost, and other attributes required to assess that asset’s 10-year reinvestment requirements. SGR investments include:

  • Rehabilitation that require capital maintenance (including major overhauls, renovations, or rebuilds)
  • Replacements
  • Annual capital maintenance (generally occurs for larger assets such as tunnel or bridges, which require periodic infusions of capital to maintain SGR).

After being inventoried, the existing assets then went through the prioritization process using the risk-based prioritization approach, as described in Ramona’s blog post.  Figure 1 illustrates the risk profile of SGR investment needs for assets exceeding $10M, based on the risk of failure and the consequence of failure. The asset groups above the diagonal line carry a higher level of risk and have bigger impacts on safety, reliability, and ridership.

Ten-Year SGR Needs

Given the 10-year SGR needs total to $17B alone, what are some of the major investments that are involved?

  • Railcar Replacement and Rehabilitation Program: $5B over the next 10 years, which is about 28% of total SGR needs.
  • Track and Structure Rehabilitation Program & Rail Systems Program: $3B each, to reach and sustain SGR. The combined $6B for both programs will cover fixed rail, guideway structures, track maintenance equipment, electrification, communications, signals, and other related assets.
  • Bus & Paratransit Program: $2.3B for fleet, facilities, and maintenance equipment.
  • Stations and Passenger Facilities Program: $2.4B to improve or upgrade platforms, station structures, vertical circulation, fare collection, and parking facilities.
  • Business Support Program: $1.7B to maintain and upgrade software and hardware, supporting equipment and services, as well as the Metro Transit Police Department’s assets.

Backlog and Compliance Needs

Metro’s SGR needs include $6.66B in backlog, also known as deferred asset needs. The assets in the backlog require immediate reinvestment as they are past their useful lives or require rehabilitation or replacement due to compliance issues. Metro’s backlog needs make up approximately 16% of Metro’s total asset base across all asset categories. The largest proportion of backlog are in major systems such as traction power and train control (Figure 2) with guideway elements (i.e., track, tunnels, bridges, and other structures) making up the next largest portion of deferred needs. About 30% of the backlog are compliance based investments such as safety directives to replace track circuits and improve tunnel ventilation. These items, totaling $2B in needs, have been marked as priority as they are needed to address compliance and/or regulatory requirements.

Scheduled SGR Needs

Over the next ten years, different assets will be due for scheduled SGR investments. For example, besides the ongoing replacement of the 1000- and 4000-series rail cars, Metro will need to complete the replacement of the 2000-, 3000-, and 5000-series rail cars during the period of the CNI, along with rehabilitation of all fleets to maintain SGR.

Given that Metro’s capital budget averaged $1B a year for the past six years, maintaining assets in a SGR as identified by the CNI would require an annual average of $1.7B in the capital budget – a 62% increase above today’s level. To support CNI’s SGR investments, Metro would need the region to significantly increase funding to execute these important needs and keep Metro healthy into the future.

What do you notice in this list of repair needs? Are there any surprises?

Prioritizing Metro’s Capital Investment Needs

December 21st, 2016 No comments

Metro used a risk-based multi-factor methodology to score and rank its 10 year capital needs.

Metro’s 2016 Capital Needs Inventory (CNI) aims to capture and quantify Metro’s existing and anticipated capital needs over the next ten years. With our needs far outpacing available funding, prioritization of capital needs is critical. But with the ever present constraints of budget, time, and staffing, how do we determine how to prioritize our new and existing needs across a 10 year period? Metro used a risk based approach to develop its 10 year capital needs prioritization.  Each criterion is defined based on the impact of an investment to improve an asset’s condition, to thereby improve Metro’s state of good repair or to mitigate asset related risks.

The risk-based prioritization approach is illustrated above.  This approach considers both the likelihood of asset failure and consequence of asset failure. The scoring uses weighted criteria, to represent either the likelihood or consequence of asset failure. For instance, the scoring helps us to decide if it is more urgent to replace one kind of asset over another in any given year, given agency priorities and finite resources.  A safety focused weighting scenario, based on the extent that an asset’s failure would affect overall system and rider safety was developed to reflect Metro’s core mission and values.  It was also important that Metro’s weighting criteria be aligned with its larger strategic goals. The image below demonstrates how Metro’s strategic goals were aligned with CNI scoring weights.

 

Once Metro’s 10 year capital needs were identified and compiled, they went through several rounds of prioritization testing based on the risk-based approach and generated prioritization scores for individual assets in the asset inventory.

After the completion of CNI, the identified capital needs must be further verified and then converted into build-able projects through a design and engineering process, which will define actual capital projects with scopes, schedules, cost estimates, and delivery methods.
