AOC’s Utility Tunnel Improvement Plan: No Information on Two Tunnels
Without information on the condition of the two tunnels that remain to be assessed, AOC’s plan lacks a full picture of tunnel conditions, the asbestos hazard, the work that needs to be done, and the cost and time it will take to complete the necessary work. In addition, the plan does not include a discussion of options for addressing the immediate and short-term needs of the tunnels.
From the plan, it is not clear whether AOC considered various options for addressing the tunnel problems or explored the cost, benefits, advantages, and disadvantages of different options before determining what work to include in the plan. AOC does indicate in the plan that it will conduct an alternatives study to evaluate the long-term use of the existing tunnels and options for meeting the Capitol Hill Complex’s future utility distribution needs.
AOC officials said they wanted to address the total utility distribution system’s needs in their alternative studies to ensure that Congress has a complete understanding of the system’s requirements and associated costs. While the immediate improvements might need to be done before an alternatives study can be completed, AOC has reported needing more than $100 million to address problems in the tunnels before it identifies and considers the different options for resolving the problems.
Thus, Congress does not have assurance that the proposed improvements and costs provide the best solutions for solving the problems in the tunnels. In addition, the plan focuses only on needs in the walkable tunnels and, as AOC points out, does not address the buried steam lines or utility vaults, where, according to AOC officials, other problems, such as asbestos, are known to exist.
AOC recognizes that the current plan does not fully respond to the questions raised in the committee’s report. According to AOC officials, they are continuing to develop the requested information and will provide it to the committee when available. They stated that the plan does not include all of the requested information because they could not complete the work in the time allotted. AOC officials said they wanted to be sure they addressed the total utility distribution system’s needs in their alternatives study to ensure that Congress has a complete understanding of the systems requirements and associated costs.
