“…For example, in studies of construction processes, Chae et al used accelerometers to monitor the health condition of suspension bridges (Chae et al 2012); Lee et al used accelerometers to evaluate pavement skid (Lee et al 2009); and Rinehart and Mooney applied gyroscopes to the study of earthwork compaction. Other researchers have focused on construction vehicle tracking (Lu et al 2007), activity identification (Cheng et al 2013;Joshua and Varghese 2010), or equipment management (Ahn et al 2013). However, IMUs also have the following limitations.…”

Construction companies in Hong Kong suffer huge losses due to labor fatalities and injuries. More than 25% of all of the injuries and fatalities in all industries in Hong Kong are caused by the construction industry. Different from the U.S., whose top injury cause is fall to lower level for fatal injuries (34%) and nonfatal injuries (23%); the most frequent type of injuries in Hong Kong is lifting and carrying (19.2%). Recently, automated 3D sensing systems (Kinect) have been employed to identify motion related hazards to improve construction safety condition. However, limitations (such as extreme light conditions, occlusions and misrepresentations) of 3D sensing systems hinder its application in engineering practices. To resolve those limitations, this research proposed a coupled system, which integrates and synchronizes the Kinect with Inertial Measurement Unit (IMUs). With the help of the coupled system, IMUs could uninterruptedly collect motion data (accelerations and angular rates) even under extreme light conditions or under occlusions; while Kinect could provide a reference system for IMUs to construct postures. The whole sensor network will be able to capture complete and reliable data, even if Kinect fail to work properly. Moreover, the proposed coupled system will also promote other human related research, such as productivities and labor tracking.

“…By employing 29 different GSM channels, a median accuracy ranging from 1.94 to 4.07 m was obtained in indoor objects localization [17]. The use of Wireless Network Technologies, such as Wi-Fi [18], Bluetooth [19], Wireless Local Area Networks (WLAN) [20,21] or ZigBee [22], did not achieve better localization accuracy. Ultra-Wide Band (UWB), Indoor GPS positioning and Radio Frequency Identification (RFID) technology were also evaluated, providing an uncertainty in estimating mobile objects localization in the order of cm [20,23].…”

A system for accurate localization and tracking of remote objects is introduced, which employs a reference frame of four coplanar ultrasound sources as transmitters and miniature microphones that equip the remote objects as receivers. The transmitters are forced to emit pulses in the 17 -40 kHz band. A central processing unit, knowing the positions of the transmitters and the time of flight of the ultrasound signals until they reach the microphones, computes the positions of the microphones, identifying and discarding possible false signals due to echoes and environmental noise. Once the microphones are localized, the position of the object is computed by finding the placement of the geometrical reconstructed object that fits best with the calculated microphones positions. The operating principle of the localization system is based on successive frames. The data are processed in parallel for all the microphones that equip the remote objects, leading to a high repetition rate of localization frames. In the proposed prototype, all the computation, including signal filtering, time of flight detection, localization and results display, is carried out about 25 times per second on a notebook PC.

“…However, with the development of these urban centres comes increased difficulty in the construction process (Rahman, et al, 2008;Lambeck and Eschemuller, 2008), particularly in effective management of materials (Huang and Hsu, 2003;Lu, et al, 2007). This is due to the congested nature of the urban environment (Singer, 2002), where many city centre developments are spatially restricted.…”

Purpose: The purpose of this paper is to identify best practice relating to the effective management of materials in an urban, confined construction site, using structural equation modelling.Design/methodology/approach: A literature review, case study analysis and questionnaire survey are employed, with the results scrutinised using confirmatory factor analysis in the form of structural equation modelling. Findings:The following are the leading strategies in the management of materials in a confined urban site environment; (1) Consult and review the project programme, (2) Effective communication and delivery, (3) Implement site safety management plans, and (4) Proactive spatial monitoring and control. Research limitations/implication:With the relentless expansion of urban centres and the increasing high cost of materials, any potential savings made on-site would translate into significant monetary concessions on completion of a project.Originality/Value: As on-site project management professionals successfully identify and implement the various strategies in the management of plant and materials on a confined urban site, successful resource management in this restrictive environment is attainable.
