In 1999, the Singapore Government envisioned a need to transform the construction industry through the Construction 21 Blueprint by a strategic vision. In line with the broader plan to develop Singapore into a knowledgedriven economy, this industry aspires to become ‘a World Class Builder in the Knowledge Age’. And earlier, as part of the IT 2000 master plan for Singapore, the Construction Real...

We construct a map injecting the set of infrastructure ideals in a real function field into the class group of the correspoding hyperelliptic curve. This map respects the ‘group-like’ structure of the infrastructure, as a consequence of this construction we show that calculating distances in the set of infrastructure ideals is equivalent to the DLP in the underlying hyperelliptic curve. We also...

End User Development offers technological flexibility to encourage the appropriation of software applications within specific contexts of use. Appropriation needs to be understood as a phenomenon of many collaborative and creative activities. To support appropriation, we propose integrating communication infrastructure into software application that follows an“easy-to-collaborate”-principle. Su...

Monitoring and inspecting infrastructure systems are tasks as old as construction itself. Depending on the phase in their life cycle, these infrastructure systems have to be maintained, repaired, refurbished, or reconstructed. To ensure current and up-todate information about each piece of infrastructure, inspectors have to go and visit each part of the system to record the condition of each co...

The world wide web provides an integrating platform for intra and inter-organizational systems. Understanding how the many actors interested in web infrastructure influence design, development and practice can provide insight as to how organisations can manage and make effective use of web infrastructure. The socio-technical perspective views information systems as being socially constructed by...

Decision making for effective infrastructure integration is challenging because the performance of long-lasting facilities is often difficult to foresee or well beyond the designer’s control. We propose a new approach for integrating the construction/retrofitting of two or more types of facilities. Infrastructure integration has many perceived benefits, but practitioners also express serious do...

1 Securing the supply and equitable allocation of fresh water to support human well-being while sustaining healthy, functioning ecosystems is one of the grand environmental challenges of the twenty-first century, particularly in light of accelerating stressors from climate change, population growth and economic development. Rehabilitation of ageing infrastructure and construction of new infrast...

In according to quantity of various consumption materials in construction sites of complex projects such as oil industry, infrastructure, and large scale commercial, management and monitoring of materials can affect on the final time and cost of project’s activities. In today’s world of rising labor costs and labor shortages, automated materials tracking can provide some advantage to impr...
