The Army is tasked with managing the cultural resources on its lands. For installations that contain large numbers of historic farmsteads, meeting these requirements through traditional archaeological approaches entails large investments of personnel, time and organization capital. Through two previous projects, Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL) cultural resource management personnel developed a methodology for efficiently identifying the best examples of historic farmstead sites, and also those sites that are least likely to be deemed eligible for listing on the National Register of Historic Places. This report details testing the applicability of the methodology to regions across the country. Regional historic contexts were created to assist in the determination of “typical” farmsteads. The Farmstead/Ranch Eligibility Evaluation Form created by ERDC-CERL researchers was revised to reflect the broader geographic scope and the inclusion of ranches as a property type. The form was then used to test 29 sites at five military installations. The results of the fieldwork show this approach is applicable nationwide, and it can be used to quickly identify basic information about historic farmstead sites that can expedite determinations of eligibility to the National Register.

In November 2019, U.S. Marines, Air Force, and Army Corps of Engineers personnel demonstrated the viability and simplicity of three-dimensionally (3D)-printed construction in a controlled environment at the U.S. Army Engineer Research and Development Center—Construction Engineering Research Laboratory in Champaign, Illinois. The tri-service exercise spanned three days and culminated in the construction of three 1 m × 1 m × 1 m (3 ft × 3 ft × 3 ft) concrete dragon’s teeth (square pyramid military fortifications used to defend against tanks and armored vehicles) and several custom-designed objects. The structural components were printed using a custom-built, gantry-style printer called ACES Lite 2 and a commercially available, proprietary mortar mix. This paper examines the viability of using 3D-printed construction in remote, isolated, and expeditionary environments by considering the benefits and challenges associated with the printing materials, structural design, process efficiency, labor demands, logistical considerations, environmental impact, and project cost. Based on the results of this exercise, 3D-printed construction was found to be faster, safer, less labor-intensive, and more structurally efficient than conventional construction methods: the dragon’s teeth were printed in an average of 57 min each and required only two laborers. However, the use of commercially procured, pre-mixed materials introduced additional cost, logistical burden, and adverse environmental impact as compared to traditional, on-site concrete mixing and production. Finally, this paper suggests future applications and areas of further research for 3D-printed construction.

U. S. Army Corps of Engineers Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL), and Carlyle Consulting’s John Carlyle conducted a leak detection survey at a U.S. Army Installation. The age of pipes in the distribution system ranged from 20 to 60 years. The thrust of the work was to acoustically survey all of the underground pipelines constituting the installation’s potable water distribution system and find any leaks. The results of the survey were that 6 leaks were discovered in the main lines, 63 leaks associated with fire hydrants, freeze proof hose bibs, water meters, etc., and 33 leaks inside buildings. Over two thousand acoustic measurements were made in order to obtain these results.

Oregon’s Coastal Bridge Program was designed to preserve the economic and cultural resources invested in Oregon’s coastal bridges. The Oregon Coast Highway contains a significant concentration of bridges listed on or eligible for the National Historic Register. Many of these reinforced concrete structures are suffering extensive corrosion damage resulting from years of exposure to the marine environment. Oregon has developed this program to evaluate, prioritize, and preserve these magnificent bridges. Preservation of these bridges has relied on the innovative application of cathodic protection technology. This new technology has been applied successfully through a project design and construction process that includes ongoing interaction among design engineers, researchers, construction project management personnel, and contractors.

Water Handling

Scale, corrosion and the and biological growth in industrial water handling processes result in reduced water flow though pipes, reduced heat transfer, and pump failures. Preventative treatments for these problems are based upon chemical compounds that are most often toxic and environmentally persistent. Manufacturers continue to introduce new chemicals and treatment programs onto the market, and old products have been discontinued. Many manufacturers claim that the new chemical and treatments are more environmentally friendly and safer for the plant workers and the users. The U.S. Army Engineer Research and Development Center Construction Engineering Research Laboratory has undertaken a research effort to look at these new chemical treatments. The objective of this work was to develop “green” water treatment chemicals that control biological growth, corrosion and scale while reducing or eliminating the generation of toxic substances during the manufacture, use, and disposal processes.

Preliminary Description

The Texas State Department of Highways and Public Transportation (SDHPT), Highway Design Division, in cooperation with the Office of the State Governor, The Office of the State Historic Preservation Officer, and the City of Laredo, has recently investigated the approach roadway and the bridge site of the proposed Colombia-Laredo International Bridge across the Rio Grande, in Webb County, Texas. The work was conducted to identify cultural resources in these areas and to offer a preliminary description and evaluation of historic properties considered to be potentially eligible to the National Register of Historic Places. One historical archaeological locale, 41WB205 (portions of the early 20th century mining community of Darwin) and one prehistoric terrace occupation zone, 41WB206, were investigated. Although the portion of 41WB205 within the projected roadway has been severely impacted by modern alteration, the larger and less disturbed surrounding site area is considered to be potentially eligible for the National Register.

Archeological, archival, and geomorphologic investigations were conducted for the proposed Pharr-Reynosa International Bridge Project in Hidalgo County, Texas, by Prewitt and Associates, Inc. from October 12-27, 1992. The purposes of these investigations were to locate and record any cultural resources within the project area, determine their eligibility for listing on the National Register of Historic Places and designation as State Archeological Landmarks, and to provide an overview of the Holocene geomorphic history of the project area. The geomorphic history of the project area suggests that the Rio Grande has experienced continuous channel aggradation from the end of the Pleistocene to ca. 1000 B.P. Climatic changes and diminishing sediment loads led to channel incision around 1000 B.P., forming a low late Holocene terrace and resulting in increased sinuosity and a decreased channel width-to-depth ratio. The investigations included a stratified sample survey of approximately 162 hectares (400 acres) and the excavation of 16 backhoe trenches and 14 shovel tests. A total of 10 sites, consisting of 10 historic and 2 prehistoric components, were documented. Six standing architectural properties, each consisting of a structure or groups of structures, also were documented. Four of the sites (41HG153, 41HG155, 41HG156, and 41HG158) are considered to be potentially eligible for listing on the National Register of Historic Places and for designation as State Archeological Landmarks. Two of the architectural properties - the Carmichael and Sorenson farmsteads - also may be eligible for listing on the National Register. The four potentially eligible sites consist of four historic and two prehistoric components. The historic components date from the Texas Republic period to the early twentieth century, representing the establishment and development of the EI Capote Ranch community. The two prehistoric components (41HG153 and 41HG158), of which only 41HG153 is potentially eligible, represent Late Prehistoric and unknown prehistoric components, respectively.

Most open repositories present a similar interface and workflow to publish data resultant from different types of research methods. Publishing simulation datasets is challenging due to the iterative nature of simulations that generate large numbers and sizes of files, and their need for detailed documentation. DesignSafe is a web-based open platform for natural hazards engineering research where users can conduct simulations in high performance computing resources, curate, and publish their data. Working closely with experts, we completed a data design project for curation and representation of simulation datasets. The design involved the creation of a data and metadata model that captures the main processes, data, and documentation used in natural hazards simulation research. The model became the foundation to design an interactive curation pipeline integrated with the rest of the platform functions. In the curation interface, users are guided to move, select, categorize, describe, and register relations between files corresponding to the simulation model, the inputs and the outputs categories. Curation steps can be undertaken at any time during active research. To engage users, the web interactions were designed to facilitate managing large numbers of files. The resultant data landing pages show the structure and metadata of a simulation process both as a tree, and a browsing interface for understandability and ease of access. To evaluate the design, we mapped real simulation data to interactive mockups and sought out experts’ feed-back. Upon implementing a first release of the pipeline, we evaluated the data publications and made necessary enhancements.
