Securing a Wireless Site Network to Create a BIM-allied Work-front

The Building Information Model (BIM) serves as a framework to align all the project-related data, providing interoperability to store and retrieve information interactively. Unfortunately, the construction site itself is excluded from this interaction as the large amount of data requires high data transfer rates and ruggedized hardware. However, advanced wireless communication technologies open radically new avenues to relay large amounts of data automatically and in near real-time. Construction could be a key beneficiary of these advancements. Wireless communication integrated with BIM, GPS and the Internet is able to provide the backbone necessary for creating intelligent systems, supporting the designer in his or her office as well as workers on the work-front. This paper presents a study that documents the development and testing of prototypes designed to facilitate information sharing at the field-level during construction. The main system constitutes an information hub, called the eCKiosk, connecting “senders and receivers” both on-site as well as off-site. The system design is discussed and some of the main modules are demonstrated. Since the electronic Kiosk depends on robust connections to the wireless devices distributed across the site, reliable connectivity is essential. For this reason, the discussion includes a study of the electronic signals behaviour in an ever-changing construction site. Measurements of the signal strengths during excavation and concrete work are presented and compared with theoretical calculations used to predict wave propagation. The results show how present models overestimate signal attenuation patterns on the construction site. This is important for designing a reliable and secure wireless site networks to link BIM to the work-front

This paper presents an integrated collaborative approach for facilities management (FM),\ud which utilises the Sydney Opera House (SOH) as an exemplar case study. The approach\ud deals with Benchmarking, Procurement and Digital Modelling as a whole and develops\ud collaboration between them. It aims to achieve innovative FM strategies and models that will\ud possibly have a direct benefit role for the Australian facilities management industry.\ud The Benchmarking theme focuses on the asset maintenance of the performing art centre,\ud iconic building and facilities with similar functionalities. Critical success factors in the\ud functional areas of asset maintenance are identified against organisational objectives of the\ud SOH and key performance indicators are developed. The Procurement theme focuses on\ud the maintenance service procurement, especially for outsourcing. Procurement methods and\ud a multi-criteria assessment approach for supporting decision making are discussed.\ud Suggested collaboration between Benchmarking and Procurement includes sharing of the\ud benchmarking data and utility of key performance indicators to support procurement\ud strategies. The Digital Modelling theme develops building information modelling for facilities\ud management and investigates the potential of state-of-the-art information systems to enable\ud a future integrated platform to support facility management collaborative activities and\ud processes

Australian Collaborative Trial of Antenatal Thyrotropin-Releasing-Hormone (Actobat) for Prevention of Neonatal Respiratory-Disease

The addition of thyrotropin-releasing hormone (TRH) to antenatal glucocorticoid treatment of women at risk of preterm delivery has been reported to lower the risk of respiratory distress syndrome (RDS) in the infant, We have assessed the efficacy of 200 mu g TRH in a multicentre randomised trial
