This two-volume report describes facility layaway procedures for U.S. Army facilities, with an emphasis on Fort Dix, New Jersey. Volume I focuses on decision criteria and the economics of facility layaway. Decision matrices for choosing cost-effective layaway strategies are presented. The concepts behind differing maintenance and repair (M and R) standards are addressed. Strategies for both short- and long-term layaway periods are described. The influence of the allowed reactivation period on M and R strategies is also described. Deactivation, periodic M and R, and reactivation for buildings and utilities are discussed, as are environmental and security concerns. The report concludes that facility layaway is technically feasible at an affordable cost. This volume addresses the specific inspection and M&R items associated with all of the different systems and components for buildings and utilities. These items are presented in a checklist format. A brief explanatory section precedes each checklist.

The U.S. Army has a very large inventory of bituminous built-up roofs. Repairs and reconstruction are steadily increasing as the roofs approach the end of their service lives, making it increasingly important to better manage maintenance funds. There is a need for a systematic procedure to determine priorities and select repair strategies that will ensure a maximum return on investment. In response, the U.S. Army Construction Engineering Research Laboratory (USACERL) has developed ROOFER, an engineered management system for built-up roofs. This report demonstrates the ROOFER procedures on selected buildings at three different Army installations: Fort Meade, MD; Fort Lee, VA; and New Cumberland Army Depot, PA. The work was performed in three phases: (1) field work, (2) data processing and management, and (3) system turnover to installation personnel. The Facilities Engineering Applications Program (FEAP) demonstrations proved to be a successful implementation of the ROOFER program. ROOFER evaluates membrane, flashing, and insulation indexes separately, providing an ideal base to generate repair and replacement recommendations. The Roof Condition Index, which combines the three indexes, provides the information needed for effective network management. It is recommended that ROOFER be released for use at all military bases and private civilian sites. (Author) (kr)

The U.S. Army Construction Engineering Research Laboratory (USA-CERL) is developing a roof maintenance management system that will provide a practical, systematic procedure to determine priorities and select repair strategies for low-slope roofs. This paper describes the development and verification of the indexes for rating built-up roofs, based on a visual distress survey. Separate indexes (expressed as a numerical rating ranging from 0 to 100) were developed for the membrane and flashing components that provide a measure of the component's ability to perform its function, needed level of maintenance, and leak potential.
