“…A study that attempted to establish the cost of a VoIP deployment found this to be significantly cheaper than that of a traditional phone setup in all aspects of cabling, training, management, maintenance, telephone traffic and connection. (Corte et al, 2006). Another general problem raised by the participants was the complexity of some ICT support systems introduced within projects that sometimes require specialist knowledge not always available on site.…”

There has been increased efforts in the introduction of Information and Communication technologies (ICT) in construction to support collaboration. However there is still little focus on support for mobile users on construction sites. It can be argued that it is often on the construction site that ICT tools can offer the greatest benefits as they can enable the timely collection of information and knowledge during the build process. Convergence in networks, the merging of voice, video and data provides increased opportunities for mobile workers, allowing for a greater array of information to be shared to support collaboration on site. This paper looks at convergence, as well as other technologies including mobile computing, speech recognition and the use of multimedia content to support the construction worker on site and ensure a smooth decision making process. The paper describes several construction case studies, including the Heathrow Terminal 5 project, where decision making processes were examined, along with ICT usage. A scenario illustrating the use of advanced ICT on site was developed to gather requirements for a technical solution which could support the decision making process, and ultimately collaboration during construction. Requirements for an ICT support system were defined with the use of the case studies and scenario analysis, the proposed solution which combines many of the latest advances in ICT in a single system is then presented. It is explained and demonstrated that this could support the decision making process by allowing more information to be accessed and shared from the construction site. The use of advanced communication technologies such as convergence and Voice over Internet Protocol (VoIP) can ensure that audio information can be retrieved along with other project data to provide a clearer more fluid decision making process where all relevant project members can easily be up to date with project progress.

“…Issues of cost are valid, as the implementation of a converged network running voice, data and video would require investment, however a study of the costs of a VoIP setup found the cost significantly cheaper than that of a traditional phone setup in all aspects of cabling, deployment, training, management, maintenance, telephone traffic and interconnection apart from data/voice devices, i.e. the cost of IP phones (Corte, A., et al, 2006). The reliability of the converged network and the quality of voice calls are issues across all sectors where the technology is deployed.…”

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

“…In a simpler term, it converts voice signal which is analogue to a digital signal in your telephone before compressing and encoding it into long strings of IP packets for upward transmission over the IP network to the receiver. At the receiving end, the received IP packets reassembles in order before decompressing and processing through the use of a Digital to Analogue Converter (DAC) to generate the initial signal transmitted [2]. Its existence is basically based on two fundamental technologies, the telephone and the internet.…”
