This study uses descriptive and inferential statistics to identify cost growth Analysis of Military Construction of military construction (MILCON) at the programmatic level, while bridging the gap between Selected Acquisition Report (SAR) estimates and actual project costs. Findings of this study aid the cost community with appropriate allocation of resources in developing these estimates. Overall, Major Defense Acquisition Programs (MDAP) appear to experience more negative growth (cost savings) in MILCON estimates on reviewed SARs— typically less than 0.2% of the total program cost. SAR estimates became more accurate from the first to last SAR in comparison to the total MILCON …

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 …

Design And Construction Of Drilled Shafts For Landslides, Malek Smadi
Purdue Road School
In general, weathered shale underlain by shale interbedded with limestone is the main forma-tion that underlies many of the slopes adjacent to the Ohio River in southern Indiana. During wet periods the weathered shale exhibits a sig-nificant decrease in strength, which has led to a number of landslides. In this session several case histories will be presented where drilled shafts have been used to repair and improve the safety of homes and roadways.

This session presents constructibility problems associated with raising a bridge about 9 feet under a 765 KV line. The solution for how to work under the line while complying with OSHA requirements, utility company coordination requirements, and the overall construction schedule was difficult: shut down the power line for construction, which had to be coordinated within a narrow window and also funded. Join us for a discussion.

A Novel Self-Healing System: Towards A Sustainable Porous Asphalt, Shi Xu, Xueyan Liu, Amir Tabakovic, Erik Schlangen
Articles
Self-healing asphalt, aimed to produce a sustainable asphalt pavement using green technology, has been studied in the past two decades. Technologies including encapsulated rejuvenator and induction heating have been proposed, demonstrated in the laboratory, and gradually evaluated in field application. This paper looks into the synergy effect of the above two technologies, where induction heating serves as the asphalt damage repair mechanism, requiring just 2 min heating time and encapsulated rejuvenator will replenish (rejuvenate) aged asphalt binder and reinstate bitumen’s healing ability. Moreover, the increased temperature from induction heating could in turn accelerate the diffusion process of rejuvenator into aged …

A Life-Cycle Analysis Of The Thermal Energy Transfer In Prototypical Air Force Office Building Construction Using Best Value Insulation Standards, Michael E. Canfield
Theses and Dissertations
The United States Department of Defense (DoD) possesses over 560,000 buildings and structures around the world which require electricity to maintain and operate. The energy costs associated with the operations of these building is approximately $4 billion per year. Sustainable infrastructure management is a crucial opportunity to improve and establish a prudent, manageable, and successful DoD budget. This research identified, modeled, and simulated thermal energy-efficient standards in building construction in order to recognize the best value standards as opportunities for potential cost savings. EnergyPlus and OpenStudio Building Performance Simulation (BPS) software was used to model the energy flow into and …

An Analysis Of The Viability Of 3d-Printed Construction As An Alternative To Conventional Construction Methods In The Expeditionary Environment, Jeneé A. Jagoda
Theses and Dissertations
Conventional construction is believed by some to have reached its technological limit of performance, making it increasingly difficult for conventional construction methods to meet the U.S. military’s core standards of quality, cost, and timeliness in the expeditionary environment. While still in its infancy, 3D-printed construction has the potential to revolutionize the way the military performs construction in deployed environments. This research conducts a systematic review of the viability of 3D-printed construction to investigate whether or not it is now or could be a viable replacement for conventional construction methods, specifically in remote environments where conventional construction capability may be limited. …

Finding Patterns In Subsurface Using Bayesian Machine Learning Approach, Wang Hui
Civil and Environmental Engineering and Engineering Mechanics Faculty Publications
Stochastic simulation approaches and uncertainty quantification are usually adopted for gaining insight into variability in soil stratigraphy configurations. Previous investigations at geotechnical site characterization and interpretation can be broadly categorized into geostatistics- and process-based methods. On the other hand, modern site exploration techniques provide high-quality, dense datasets in physical spaces with high resolution, either directly from sensors (for example, cone penetration testing data) or indirectly from geophysical inversion (such as seismic inversion, electromagnetic induction inversion, and ground penetrating radar). In this work, anisotropy and heterogeneity are considered as possible patterns that inherently exist in the observations, and these are inferred …

Autonomy is a topic that is gaining speed throughout the world as labor shortages rise, wages increase the desire for greater safety in dangerous fields accelerates. One industry that has had a slower start but looks to join the autonomous bandwagon is construction. Different experts in different fields from engineers to construction managers give different timelines as to when this autonomous technology will be normally present in certain construction industries, however an accurate timeline has yet to be determined. The objective of this paper is to provide a more accurate timeline as to when autonomous heavy equipment will be prevalent …

The custom residential sector of construction currently lacks the usage of BIM management tools. This paper looks to research the current usage, advantages, and disadvantages of using BIM management software’s within custom residential construction. There will be a comparative case study held between two custom residential contractors, one with minor BIM usage and one who has fully integrated BIM software into their management procedure. The goal is to find out if BIM management is cost-effective and scalable to the custom residential industry. This information will be beneficial to the custom residential industry because it will provide custom residential general contractors …
