Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Lockwall: AMicrocomputer-Based Maintenance and Repair Management System for Concrete Navigation Lock Monoliths

摘要

LOCKWALL is a microcomputer-based maintenance management tool for conditionassessment, condition prediction, and optimal work planning for the repair and upkeep of concrete navigation lockwalls. The development and intended use of LOCKWALL parallels that of other Engineered Management Systems developed at USACERL such as PAVER, RAILER, and ROOFER. The concrete distress data, gathered by field inspection with a minimum of equipment, is used to calculate a Condition Index (CI) for each monolith in the data base. The CI indicates the condition of the concrete in each monolith. The CI thus affords a means for the uniform and quantitative comparison of the condition of concrete in one lock structure to that of another. The algorithm for computing the CI is described in REMR Technical Report, REMR-OM-4, A Rating System for the Concrete in Navigation Lock Monoliths. In time, the collected data will yield curves showing deterioration rates of concrete in service. Such curves can be used to predict future concrete condition so that maintenance managers can optimally budget maintenance money. In addition to optimal budget planning, LOCKWALL will provide maintenance managers with justification for maintenance money and automated management reports, which will result in a better condition for dollars expended.
