José María Gil Adobe: Historic Context, Maintenance Issues, Measured Drawings, and Adaptive Reuse

Abstract: The José María Gil Adobe, located on Fort Hunter Liggett, California, was added to the National Register of Historic Places (NRHP) in 1974. The building has been vacant since the early 1970s. It is a fine example of a small adobe ranch house possessing character-defining features of its period of significance of the mid-19th century on its exterior, interior, and within the site itself. This document is a reconstruction, repair, maintenance, and adaptive reuse report compiled with photographed, written, and drawn as-is conditions of construction materials of the José María Gil Adobe building and site. The building was 3D scanned to obtain the necessary information for the measured drawings. The secretary of the interior’s guidelines on rehabilitation and repair per material are discussed to provide the cultural resources manager at Fort Hunter Liggett a guide to maintain this historic building. Rehabilitation is the best option for the successful reuse of the José María Gil Adobe as it will move the building from a vacant status to an occupied status. It is highly likely that this building can again serve an appropriate use as outlined in Section 11, reflecting its appearance in the early 20th century or WWII periods.

Beneficial Use of Dredged Material: A Workshop to Explore Engineered Drainage Soils for Stormwater Management

PURPOSE: Beneficial use of dredged material in engineered soils is an alternative to achieve environmental and economic sustainability for waterway operations. Engineered soils can combine navigation and environmental dredging with municipal and commercial waste streams to create a valuable commercial soil product while reducing public operating costs, creating economic opportunity, and creating better soil products for lower cost. The need, opportunities, and challenges to establishing an Illinois Waterway-based commercial soil industry were explored by river, highway, stormwater, environmental resource managers, and industry experts in a workshop in Peoria, IL, on 4–5 September 2019.

Full-Scale Trafficability Testing of Prototype Submersible Matting Systems

Abstract: This report describes the full-scale evaluation of prototype submersible matting systems (SUBMAT) at a test site at the US Army Engineer Research and Development Center’s Vicksburg, Mississippi, site. The SUBMAT prototypes were designed to bridge the gap between high and low tide at a beach interface to enable 24-hour operation at an expeditionary watercraft landing site. This phase of the SUBMAT prototype development was intended to determine prototype system durability by applying military vehicle loads representing a combat brigade insertion across a littoral zone. The two mat systems evaluated in this study were the PYRACELL Road Building System (PRBS) and a basaltic rebar mat system. The results of the study showed that the PRBS system was able to sustain 1,000 Medium Tactical Vehicle Replacement, 350 Heavy Expanded Mobility Tactical Truck, and over 150 M1A1 main battle tank passes without significant damage. The basaltic rebar mat failed early in the test and was removed from further consideration for the SUBMAT application. Observations and lessons learned from this phase of the prototype PRBS development will be used to improve the PRBS design and modify its installation procedures for improved efficiency.

Historic Context for Railroads at Fort McCoy, Wisconsin

Abstract: This report provides a historic context for the railroads that operated within the present-day boundaries of Fort McCoy. The objective of this historic context is to deliver a useful reference for future evaluations of railroad-related resources in the installation. Ultimately, the report is in-tended to save the installation time in determining potential areas of significance for future evaluations. This is accomplished through the creation of a broad historic context for railroading in the Midwest, establishing a survey of railroad history at Fort McCoy, and providing examples of areas of significance and National Register of Historic Places (NRHP) criteria commonly applied to the historic railroad resources of the Midwest. This report does not provide NRHP eligibility recommendations for any specific resources; however, possible research questions for further study are posited in the concluding chapter.

Pattern Language for a More Resilient Future

Abstract: The Department of the Army (DA) manages millions of acres of land for military use. Military installations and other US DoD operations contain architectural structures and civil infrastructure that require continuous improvements to resiliency. This includes resiliency in the form of protection against both natural and man-made disasters. This document seeks to identify multiple risks to infrastructure and people and encourages open dialogue for creative solutions. Designers and engineers as well as other disciplines can work together to achieve higher resiliency in both new and renovated work. The following sections are created to provide a starting guide, utilizing various tools to discover the best resilient design strategies for your building. This special report will argue for actionable design strategies; drawing inspiration from historical building forms, while also looking toward emerging technologies that should be further explored.
