REMR Management Systems-Navigation Structures, Condition Rating Procedures forTainter Dam and Lock Gates

摘要

The mission of the U.S. Army Corps of Engineers has been shifting fromconstructing new facilities to maintaining the large inventory of existing facilities. The objective of this work was to develop an inspection and rating system that uniformly and consistently describes the current condition of tainter dam and lock gate structures. The objective was achieved by conducting site visits and field investigations with experts from the U.S. Army Corps of Engineers, and by using the experts' opinions to develop the rules which form the basis of the rating system. This document provides a general description of the inspection and rating system, which includes the definition of a condition index and a description of tainter gate distresses. This is followed by a detailed description of the inspection and rules for calculating condition indexes for tainter gates. (MM).
