Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Network Level REMR Management System for Civil Works Structures: Concept Demonstration on Inland Waterways Locks
Abstract
The Network Management System is based on a life-cycle analysis of the performance and costs of facilities through some analysis period, as affected by REMR policy. In a new approach to looking at facility performance and the factors which influence costs throughout its service life, referred to as 'demand responsive,' maintenance and rehabilitation are viewed as responses to the demand for repair or renewal of the facility. Treating REMR actions as demand-responsive activities requires additional elements be introduced within existing planning and management models: 1) Estimates of future resource requirements and costs of managing facilities based on predictions of structural and operational deficiencies caused by use, environment, and age; 2) Clear statements of REMR policies themselves, defining the types of preventive or corrective actions to be taken, and when/where they are to start; and 3) Relationships between the as-maintained state of the civil facility, and the impacts on both the Corps and users of the facility (in terms of preservation of facility investment, the costs, time, and reliability of transportation service provided, safety, etc.), providing a measure of the benefits (or disbenefits) of each policy at the costs computed above. This report explains the concepts involved in applying life-cycle costing to analyses of REMR policies. Keywords: Life cycle cost; Maintenance management; Repair/evaluation/maintenance/rehab.
