    • Q. Who analyzed how the post-construction risk management plan applied to the "Pensacola Bay Bridge" from the operator's point of view
    • Background:

    " FDOT Steps Up Tear-Down of Damaged Pensacola Bridge [1]"

    "Demolition activity is in full swing at the Pensacola Bay Bridge, as contractors work to remove multiple spans damaged by unmoored construction barges during Hurricane Sally last month."

    "Skanska has also recovered 15 of 27 construction barges that broke loose on Sept. 15, which the company attributed to the hurricane's unexpected intensification and eastward track shift as it approached the Gulf Coast. The barges were being used to construct a new structure to parallel the damaged bridge, which was opened last year."

    • "multiple spans damaged by unmoored construction barges. . ."
    • "attributed to the hurricane's unexpected intensification and eastward track shift as it approached the Gulf Coast."

    This is a great question and might be better posed in a broader risk management context as it's not an uncommon occurrence. While the Pensacola Bay Bridge may be the most recent bridge to suffer from collision with maritime assets that have gone adrift in a storm, it's one of many. A Google search brings up "bridge damage barge" brings up multiple occurrences. It's also a well-known - or should be well-known - risk for bridge owners and designers from maritime vessels losing power or situational awareness, e.g., Sunshine Skyway Bridge.

     What is the status of our profession's initiatives to prepare and deliver an "Operations Phase Risk Management Plan" to guide the potential operational risks once construction is complete?

    The complete life cycle of a construction project is subjected to threats from various risks.

    Pages 316-337 | Received 17 Nov 2011, Accepted 21 Feb 2012, Published online: 02 Oct 2012

    ABSTRACT

    The risk attributes in construction project is one of the widely published topics, yet there is no or little investigation whether or not risks associated with construction phase propagate over operational phase. As operation phase of the PPP projects is significantly long compared to the construction phase, understanding the impact of time and cost related construction risks over operation phase is quite important.

      Has ASCE formally addressed the clearly apparent gap I have perceived in the incomplete approach to "Program/Project Risk Management" and bring "Operations Risk Management Plans" to our stakeholders, clients, and civil engineers attention?  If so, please provide some examples.

       

      1. Do folks see this as ASCE’s to address and how?
      2. Who else could  or should address and how best to proceed?

      Hi Bill, As I internalize your concern it's one of managing risk in the operational phase of an asset. For bridges, I think collision risk with maritime vessels is a valid concern and as already indicated, is much larger than the Pensacola Bridge. Personally, before considering a solution path I'd like to know more about the problem and pose the below framing questions to you and others. This is not meant to detract from your specific questions, or be dismissive in any way, but to offer you and others a possibly more systematic way of approaching the issue.


      Where are we now

      • What is the current state of play? Are risks for bridges subject to maritime vessel collision being deliberately / consistently managed?
      • Are there existing guidelines and standards for bridge designs to manage maritime vessel collision risk?
      • Who would have responsibility for creating / updating such a guideline or standard?
      • How large is the risk and how does it compare to other risks?
      • What is the consequence of doing nothing?


      Where do we want to be

      • What does success look like?

       

      How do we get there / Decisions

      • Who are the principal customers / users?
      • Is this an awareness issue or issue for codification of some sort?
      • Who should ideally take the lead in addressing, e.g., building and executing an action plan?

       

      This is not an exhaustive list of framing elements and I'm sure can be added to.

       

      Regards,

      Just as I expected Mitch, OUTSTANDING reflections.

      Helps lose the knee-jerk other plan:

      • Ready!
      • Fire!
      • Aim!
      As I work to learn who, besides yourself, will see the enormous challenge to add to our traditional
      project/program phase sequences the "Missing Link."

       A state-of-the-art comprehensive report outlining the current status and research needs in the life cycle of civil structure and infrastructure systems. This book examines:

      1. Physical, chemical, and mechanical processes involved in the degradation mechanisms of concrete and steel structures located in severe environments;

          2. Methods and strategies for life-cycle design and assessment of deteriorating structural systems under uncertainty;

          3. Life-cycle management concepts for structures and infrastructure networks under uncertainty and the application of such concepts in the management process; and

          4. Principles and implications associated with the scheduling and application of maintenance policies for deteriorating structures and infrastructure networks.

      This book serves as a valuable resource to engineers, managers, and government agencies concerned with life-cycle design and maintenance of civil structures and infrastructure systems.
