Locating building components that need to be worked on during maintenance tasks is critical for timely repair of the component and mitigation of the damage. The process of locating a component or a person in a facility is called indoor localization. The objective of this research study is to analyze the feasibility of three indoor localization technologies for supporting operations and maintenance (O&M) field tasks; namely, wireless local area network (WLAN), radio frequency identification (RFID) tags, and inertial measurement units (IMU). These technologies have been selected on the basis of the requirements of the localization needed for supporting O&M field activities. A previous work has been extended, which tested RFID-based locations in an indoor environment, by testing the three selected technologies in the same test bed and using the same hypothesis and fingerprinting approach developed in the previous work. The two main motivations behind using the same test bed and same approach are to have the same baseline to evaluate the performance of the three technologies and to evaluate the performance of RFID-based localization over longer periods. The results in the present study show that RFID-based localization suffers from a decrease in signal strength levels over several years, and that WLAN-based localization suffers from variations in signal strength. They also show that IMU-based localization suffers from drift in the sensors of IMU. Prior knowledge of the layout of a facility can improve the performance of WLAN, RFID, and IMU-based localization.

Building-Information-Modeling-Based Earthquake Damage Assessment for Reinforced Concrete Walls Anil, Engin Burak; Akinci, Burcu; Kurç, Özgür; Garrett, James H. (American Society of Civil Engineers (ASCE), 2016-07-01) Engineering analysis to quantify the effects of earthquake forces on the structural strength of components requires determining the damage mode and severity of the components. The analysis requires strength computations and visual damage assessments, which are information intensive, potentially error-prone, and slow. This study develops a building-information-modeling (BIM) based approach to support the engineering analysis of reinforced concrete structures. In the proposed approach, the damage information ...
Information Requirements for Design and Detailing of Reinforced Concrete Frames in Multiuser Environments Anil, Engin Burak; Unal, Gokhan; Kurç, Özgür (American Society of Civil Engineers (ASCE), 2012-07-01) The design and detailing of reinforced concrete frames is a complex process that requires intensive real-time information exchange between various design tasks. The monolithic behavior of concrete, differences in the geometric representation of structural members during the analysis and design stages, and design code requirements throughout the process add new dimensions to the problem. Additionally, especially in large projects, reinforced concrete structures are designed and detailed by several engineers ...
Ontology for Relating Risk and Vulnerability to Cost Overrun in International Projects Fidan, Gulsah; Dikmen Toker, İrem; Tanyer, Ali Murat; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2011-07-01) Risk management is about identifying risks, assessing their impacts, and developing mitigation strategies to ensure project success. The difference between the expected and actual project outcomes is usually attributed to risk events and how they are managed throughout the project. Although there are several reference frameworks that explain how risks can be managed in construction projects, a major bottleneck is the lack of a common vocabulary for risk-related concepts. Poor definition of risk and patterns...
Seismic behavior and improvement of autoclaved aerated concrete infill walls Binici, Barış; Canbay, Erdem; Uzgan, Ugur; Eryurtlu, Zafer; Bulbul, Koray; Yakut, Ahmet (Elsevier BV, 2019-08-15) Performance of infill walls in reinforced concrete (RC) frames is generally questionable under the combined action of in-plane and out-of-plane seismic demands. Despite the vast number of tests investigating the behavior of brick masonry infill walls in RC frames, past research is limited for infill walls made of Autoclaved Aerated Concrete (AAC) blocks. In the first part of the study, six single-bay single-story half-scaled RC frames were tested under the action of in-plane cyclic displacement excursions a...
Comparison of experienced and novice cost estimator behaviors in information pull and push methods Kiziltas, Semiha; Akinci, Burcu; Gonzalez, Cleotilde (Canadian Science Publishing, 2010-02-01) Construction cost estimators mainly use analogy-based decision-making processes while estimating activity production rates in new bids They need to search information items that will help them in understanding the differences and similarities between the current and previously Completed projects to select appropriate production rates and make necessary adjustments to the selected production rates. The objective of the study is to understand the effect of information pull-push methods on the behaviors of cos...
