“…Many different wireless technologies have been tested on construction sites including different infrastructures and communication devices (Bowden, 2002, Meissner et al, 2001, Beyh et al, 2004and de la Garza et al, 1998. The Construction Site Mobile Operations Support (COSMOS) (Meissener et al, 2002) and Mobile Integrated Communication in Construction (MICC) (Deguine et al, 1999)projects tested various technologies on the construction site including DECT (Digital Enhanced Cordless Telecommunications), GSM (Global System for Mobile communications), WLAN (Wireless LAN), and TETRA (Terrestrial Trunked Radio).…”

“…Many of these technologies have been reviewed with an emphasis on data communications (Bowden, 2002, Meissner et al, 2001, de la Garza et al, 1998, CusBabic et al, 2000. Data communications occuring on the construction site usually require less bandwidth than voice communications and are less demanding on network resources.…”

“…The network can be set up to mimic the traditional cellular network, with access points marking the centre of each cell. This way, the network could be enlarged with an increased number of access points being 'daisy-chained' together as shown in figure 4 (De la Garza et al, 1998, Ward et al, 2004. Installing a wireless network on a construction site is very different to a traditional office.…”

“…The outdoor environment has a major impact, with the effects of weather and dust which mean that the wireless technology should be rugged enough to cater for that. Garza et al, 1998) With tests of wireless networks on construction sites, the researchers have used standard wireless equipment in rugged containers to keep them secure in the construction environment. Manufacturers of wireless equipment have developed systems specifically for the construction industry that are capable of withstanding the conditions on site.…”

Abstract:Converged networks which carry voice, video and data have promised cost savings for its users. Much of the construction industry spends over £1 million on communication, mainly from the construction sites to headquarters. With the use of IP telephony and converged networks, the cost can be reduced significantly. Using existing 802.11b/g wireless networks, access to the voice network can be delivered on a construction site allowing mobile users access to personnel as well as data instantly.Voice over Internet Protocol (VoIP) plays a major role as a catalyst for convergence. Although it is sometimes viewed as just another means of transporting voice communication, the use of one single network provides opportunities for advanced applications that can support and enhance the construction workflow. The introduction of Voice over a Wireless Local Area Network (VoWLAN) allows the opportunities to expand onto the construction site.This paper looks at the emergence of VoIP and examines how this can be brought to the construction site. The paper reports on research carried out with the UK construction industry, identifying communication trends as well as information storage of this communication. With this information, the paper attempts to identify processes where the technology can provide key benefits

“…Manual methods for data collection are time consuming and prone to human error and may result in delayed corrective actions with adverse cost consequences. Failure in effectively tracking construction progress and in retrieving related information can result in schedule delays and cost overruns (De la Garza and Howitt, 1998). Earthmoving operations have received considerable attention from researchers and industry professional (Alkass and Harris, 1988, Hajjar and AbouRizk 1999, Marzouk and Moselhi, 2004, and Moselhi and Alshibani 2009.…”

Hauling trucks are important part of equipment fleets for large earthmoving operations such as those encountered in dams and highway construction projects. This paper presents an automated methodology for tracking and estimating productivity of hauling trucks fleet operations in near-real-time. Recent advancement in automated site data acquisition technologies made their use in tracking and monitoring of construction operations feasible. However, these technologies fail to track hauling truck fleets due to the change in the cut and fill locations from one cycle to another; making tracking and progress reporting difficult and inaccurate. In addition, there is very little work done utilizing data sensed directly from equipment, for example sensing when truck dumping bed is raised during the dumping process. The technologies deployed in the developed method are Radio Frequency Identification (RFID) and equipment control sensors. Low cost passive RFID tags are attached to hauling trucks and fixed RFID readers are attached to loaders or excavators. The read range of the used RFID tag is centimeters, to be activated only when a loader with an attached RFID reader is loading a truck. On the other hand, control sensor is connected to the truck control system and operated by the motion of its movable bed. The function of control sensors is to record the signal time when the truck operator gives order to the truck control system to raise or lower truck bed. The captured data is then transferred wirelessly from the RFID reader and control sensor to a computer housed in one of the temporary offices onsite and subsequently to the main server in the contractor's head office. Fusing the data captured from RFID reader and control sensor is used to identify loading, travel, dumping and return time that constitute the hauling truck cycle time. The collected data is analyzed and processed automatically, without human intervention, to calculate the productivity of the hauling truck and to report it directly to onsite personnel. Relational database is developed to support the implementation of the proposed method. The developed database is used to process the data captured by the RFID and the control sensor to calculate the productivity achieved in cutfill operations in near-real-time. The developed methodology is expected to facilitate early detection of discrepancies between actual and planned performances.
