The guide explains how executives can incorporate and communicate capital funding needs for tunnel improvements as part of their overall transportation system funding. Additionally, the guide delivers a process for prioritizing needs, using an overall measure of effectiveness that is calculated using a risk-based urgency score, and developing capital funding and staffing programs to accomplish tunnel preservation goals. The guide also serves as a training tool for new personnel. The contractors final report is available from the project description page.
Water infiltration is a common problem in tunnels. Such infiltration accelerates the deterioration of the structure and elements within and creates hazards in the form of icicles and slippery roadways. The severity of water infiltration often reflects various factors, so determining the appropriate remedy is challenging and frequently requires an extensive investigation to understand the source and location of the leak, the structural details of the tunnel, and the geology of the surrounding substrate. NCHRP Synthesis 627: Practices for Controlling Tunnel Leaks, from TRB's National Cooperative Highway Research Program, documents the methods and practices used by state department of transportation tunnel owners to control tunnel leaks."--Publisher's website.
