Trust Agreement

"The MDTA covenants that it will cause independent engineers or engineering firms or corporations having a nationwide and favorable reputation for skill and experience in such work to make an inspection of the Transportation Facilities Projects periodically in accordance with industry standards (but at least annually), to submit to the MDTA a report or reports setting forth their findings as to whether the Transportation Facilities Projects have been maintained in good repair, working

  • rder and condition. Promptly after the receipt of such reports by

the MDTA, copies thereof shall be filed with the Trustee and made available upon request for review to the owner of any Bond issued hereunder."

Evaluation of th the Syste tem

MDTA Discussed New Direction and Improvements to Program.

– Considered comparable owners’ procedures. – Participated in peer reviews. – Need to be Condition Based verses Defect Based. – Need to have “stand alone” inspection reports. – Need to contain greater detail and be more descriptive. – Opportunity to automate the documentation. – Opportunity to directly link findings with repairs.

Evaluation of th the Syste tem

Results: Key Outcomes

– Increase funding for inspections to obtain the desired Hands On Inspection in lieu of a Maintenance Inspection. – Establish defined inspection procedures and reporting.

  • Span by span reporting; not just overall bridge

– Develop an Inspection Manual to document procedures and promote consistency. – Develop a Data Management System to record and manipulate findings data.

  • Have the ability to track defects from original finding to repair

and to verified completion.

– Get priority findings addressed rapidly.

2012 MdQI Conference Quality Transportation- A Hybrid Approach

In Inspection Procedures

For spans less than 40 feet above the ground or water surface, inspection of the superstructure and elevated substructure shall occur from a boat or from the ground. For spans greater than 40 feet above the ground or water surface, the inspectors shall perform a visual inspection of a minimum of 20% of the elements in the span. Access may be gained using catwalks or access equipment.”

Defined Inspection Types and Procedures

– Biennial

  • Hands-on technique
  • Railroad spans on 6 year cycle for hands-on

– Interim

  • Visual technique
  • Hands-on technique where needed.

In Inspection Procedures

Defined Inspection Report

– Biennial

  • Full stand alone document including plans,

condition ratings, condition notes and recommended repairs

  • Typically 40 to 80 pages for a workhorse structure.

For signature structures, can be up to 1500 pages.

– Interim

  • Viewed as a supplement or follow-up to the previous

biennial inspection report.

  • Can be as small as 4 pages for a workhorse bridge

MDTA assigns the priority of the TO addressed. Monies allocated and utilized and percentage of completion for the TO is easily viewed.

2012 MdQI Conference Quality Transportation- A Hybrid Approach

Repairs and Preventive Maintenance

  • Defects are triaged by the MDTA engineering group and

repair priorities are able to be changed, if warranted, within the ASIR software. Consultant reports reflect these

  • changes. Example…
  • Defects under a task order that have been tracked and

closed out are no longer viewed in the inspection reports the consultants utilize.

  • The MDTA is able to use one centralized system to handle

facility inspection data from the start of inspection, to the prioritizing of defects, to the repair of these defects.

  • Prioritizing of repairs assists the MDTA in allocating funds.

What’s next?

Develop data queries for specific defects to ease in repair packaging. Use inspection data from multiple cycles to trend and monitor costs of inspections. Develop asset health trends to schedule preventive maintenance and system preservation.
