Development of Condition Indexes for Building Exteriors

摘要

The Army's significant annual investment (about $1.1 billion) in buildingmaintenance and repair (MR) dictates that facility managers use some simple, practical condition assessment method to identify and prioritize maintenance requirements for all buildings. The U.S. Army Construction Engineering Research Laboratories (USACERL) is developing the BUILDER Engineered Management System (EMS), a microcomputer-based decision support system specifically designed to standardize and add structure to the maintenance management of military buildings, but also generally applicable to all public and private buildings. BUILDER will use an objective, repeatable condition assessment method-in the form of condition indexes-to help facility managers: (1) assess current conditions, (2) predict future conditions, (3) establish deterioration rates, (4) determine and prioritize current and long range MR needs, (5) formulate budgets, and (6) measure the effectiveness of MR. BUILDER will require condition indexes for all the component/material combinations that comprise the many diverse building systems. This study developed the methodology to derive the needed condition indexes for exterior closure systems.
