The Applicability of a Geomagnetic Field based Positioning Technique with Mobile Phone to Underground Tunnels

T. Makkonen, R. Heikkilä, A. Kaaranka
Pages 953-959

In underground mines and tunnels accurate and continuous positioning of moving machines and humans has been studied extensively. Geomagnetic field based positioning is an interesting possibility for this measurement need. Using a commercial smart phone and a new calculation service provided by a Finnish company, a feasibility and accuracy assertion ...

Decision Support Model with Life Cycle Assessment for Building in Design Phase

Chia-Chen Wei, Chia-Chi Hsiang, Tzu-Chi Shan
Pages 966-971

The building materials and structural form chosen in design phase not only affect the costs for construction, but also decide the costs for maintenance. However, the large amounts of maintenance costs are not easy to estimate. This article proposes a decision support model adopting life cycle assessment to assist the ...

Study on the Optimal Digging Range for Intelligent Excavation

Jeonghwan Kim, Joonhyun Jang, Leeho Lee, Jongwon Seo
Pages 984-991

Excavators play an important role at construction sites owing to high application and economic advantages, but the number of skilled operators of the excavator decreased because young operators do not like to enter to construction business. Research on automation of excavator and earthwork equipment was actively done such as IES ...

Information Modelling on Mechanized Earthworks

Shigeomi Nishigaki, Katsutoshi Saibara, Shigeo Kitahara
Pages 992-999

Mechanized earthworks for post-disaster reconstruction largely forks into unmanned construction at hazardous working sites and manned one at less hazardous sites. In order to avoid secondary disasters, it is significant and required to compensate operator’s realistic sensation in order to enhance spatial awareness in the mechanized earthworks. The mechanized earthworks ...

Measurement of Theoretical Relationships in Building Information Modelling Adoption in Malaysia

Wallace Imoudu Enegbuma, Uche Godwin Aliagha, Kherun Nita Ali
Pages 1000-1008

Implementing Information technology (IT) in a system presents varied responses. Prior research models in IT adoption examine dimensions not limited to attitude, subjective norm, ease of use, usefulness, innovation including several moderating variables. Despite consistent blueprints on leverage on IT in the Malaysian construction industry master plan, the exponential growth ...
