Abstract: Currently, numerous approaches to Indoor Positioning Systems (IPSs), such as RSSI (Received Signal Strength Indication), fingerprint, PDR (Pedestrian Dead-Reckoning), and image recognition, have been developed. But each individual positioning method has unique drawbacks. In this study, we provide an IPS with a novel combined positioning method that applies Building Information ...

Assessment of Work Efficiency of HMD Viewing System for Unmanned Construction Work

Genki Yamauchi, Takeshi Hashimoto and Shin'Ichi Yuta
Pages 824-830

Abstract: This study describes a simple head mounted display(HMD) viewing system for an unmanned construction system(UCS) and an assessment of the work efficiency using the HMD system. The deployment of a UCS is a significant problem because majority of the construction machines are not compatible with remote operation. In this study, focusing ...

PPEs Compliance Technology to Legalize the Automated Monitoring of Safety Standards

Fawaz Habbal, Firas Habbal, Abdulla Al Nuaimi, Anwaar Al Shimmari, Ammar Safi and Tala Abhushuqair
Pages 838-845

Abstract: Governments are always looking to monitor safety violations on construction sites. Those violations are not only causing numerous injuries and deaths to workers but also delays and subsequently costs to the project developers. In the hierarchy of control, personal protective equipment (PPE), albeit the least effective, is still one of ...

An Approach to Enhance Interoperability of Building Information Modeling (BIM) and Data Exchange in Integrated Building Design and Analysis

Troy Nguyen and Elvis Amoah
Pages 876-883

Abstract: Achieving high energy-efficient building designs requires conducting energy analyses iteratively starting from the conceptual stage to ensure suitable selection of building components to meet energy performance requirements. In recent years, advanced BIM capabilities have allowed designers to assimilate design and energy modeling processes geared towards improving productivity. However, there are ...

Analytic Hierarchy Process as a Tool to Explore the Success Factors of BIM Deployment in Construction Firms

Shunming Liang, I-Chen Wu, Zheng-Yun Zhuang and Chin-Wen Chen
Pages 897-905

Abstract: The overall performance of a life-cycle phase under investigation can be improved if Multi-Design for X (MDFX) technique’s design guidelines are applied concurrently. However, the complexity of selecting MDFX techniques at the conceptual and detailed design stages during machine development can increase by uncertain and imprecise knowledge about the MDFX ...

3D Modeling Approach of Building Construction based on Point Cloud Data Using LiDAR

Byeongjun Oh, Minju Kim, Chanwoo Lee, Hunhee Cho and Kyung-In Kang
Pages 906-912

Abstract: LiDAR (Light Detection and Ranging) emerges as a mapping technology that provides fast, accurate, and reliable data with geometric representation of construction facilities. The technology has received high recognition especially since the importance of digital transformation in construction projects has been emphasized. However, the current state of 3D technologies including ...

Automated Clash Resolution of Rebar Design in RC Joints using Multi-Agent Reinforcement Learning and BIM

Jiepeng Liu, Pengkun Liu, Liang Feng, Wenbo Wu and Hao Lan
Pages 921-928

Abstract: The design of rebar in reinforced concrete (RC) structures is a mandatory stage in building construction projects. Due to the large number and complicated arrangement rules of rebar in each design code, it is impractical, labor-intensive and error-prone for designers to avoid all clashes (i.e., collisions and congestion) manually or ...

Automated Localization of a Mobile Construction Robot with an External Measurement Device

Selen Ercan, Sandro Meier, Fabio Gramazio and Matthias Kohler
Pages 929-936

Abstract: The localization of a robot is a crucial part of any task that involves the mobile manipulation of objects. The precise repositioning of a mobile robot within the workspace is particularly important for on-site construction in situations where the operating area is much larger than the reach of the robot ...

Analysis of the Perceptions of Beneficiaries and Intermediaries on Implementing IPD in Indian Construction

V. Paul C. Charlesraj and Vatsala Gupta
Pages 937-944

Abstract: Selection of appropriate project delivery system is key for project success. It also gains much importance in a fast developing economy like India where there is a greater emphasis on development of housing and infrastructure involving huge investments. The present practices of project delivery led to inefficiency and distrust among ...

Modelling Traffic Conditions on Fuel Use and Emissions of On-road Construction Equipment

Khalegh Barati and Xuesong Shen
Pages 945-952

Abstract: The consumption of fossil fuels by on-road vehicles is a main source of air pollution specifically greenhouse gases (GHGs) worldwide. The construction industry, due to the use of a large number of heavy-duty equipment including haulage trucks, contributes to a significant amount of fuel consumption and consequent emissions production. Due ...

Indoor Visualization Experiments at Building Construction Site Using High Safety UAV

Tomohiro Narumi, Shigeru Aoki and F. Muramatsub
Pages 961-966

Abstract: Importance has been placed on improving productivity at construction sites in a recent year, reducing bitterness and repetitive work, and improving the e?ciency of inspec- tion and management work. Since buildings usually have a unique shape, e?ciency improvement methods used in mass production plants had not been able to be ...
