Built heritage management systems : the framework of a digital tool for the conservation of Brisbane City Hall

Brisbane City Hall (BCH) is arguably one of Brisbane’s most notable and iconic buildings. Serving as the public’s central civic and municipal building since 1930, the importance of this heritage listed building to cultural significance and identity is unquestionable. This attribute is reflected within the local government, with a simplified image of the halls main portico entrance supplying Brisbane City Council with its insignia and trademark signifier. Regardless of these qualities, this building has been neglected in a number of ways, primarily in the physical sense with built materials, but also, and just as importantly, through inaccurate and undocumented works. Numerous restoration and renovation works have been undertaken throughout BCH’s lifetime, however the records of these amendments are far and few between. Between 2010 and 2013, BCH underwent major restoration works, the largest production project undertaken on the building since its initial construction. Just prior to this conservation process, the full extent of the buildings deterioration was identified, much of which there was little to no original documentation of. This has led to a number of issues pertaining to what investigators expected to find within the building, versus what was uncovered (the unexpected), which have resulted directly from this lack of data. This absence of record keeping is the key factor that has contributed to the decay and unknown deficiencies that had amassed within BCH. Accordingly, this raises a debate about the methods of record keeping, and the need for a more advanced process that is able to be integrated within architectural and engineering programs, whilst still maintaining the ability to act as a standalone database. The immediate objective of this research is to investigate the restoration process of BCH, with focus on the auditorium, to evaluate possible strategies to record and manage data connected to building pathology so that a framework can be developed for a digital heritage management system. The framework produced for this digital tool will enable dynamic uses of a centralised database and aims to reduce the significant data loss. Following an in-depth analysis of this framework, it can be concluded that the implementation of the suggested digital tool would directly benefit BCH, and could ultimately be incorporated into a number of heritage related built form.

Studies of Brisbane municipal water quality using Inductively Coupled Plasma - Mass Spectrometry and Chemometrics

This research established innovative methods and a predictive model to evaluate water quality using the trace element and heavy metal concentrations of drinking water from the greater Brisbane area. Significantly, the combined use of Inductively Coupled Plasma - Mass Spectrometry and Chemometrics can be used worldwide to provide comprehensive, rapid and affordable analyses of elements in drinking water that can have a considerable impact on human health.

Retrieving trip information from a discrete detectors network : The case of Brisbane Bluetooth detectors

Automatic Vehicle Identification Systems are being increasingly used as a new source of travel information. As in the last decades these systems relied on expensive new technologies, few of them were scattered along a networks making thus Travel-Time and Average Speed estimation their main objectives. However, as their price dropped, the opportunity of building dense AVI networks arose, as in Brisbane where more than 250 Bluetooth detectors are now installed. As a consequence this technology represents an effective means to acquire accurate time dependant Origin Destination information. In order to obtain reliable estimations, however, a number of issues need to be addressed. Some of these problems stem from the structure of a network made out of isolated detectors itself while others are inherent of Bluetooth technology (overlapping detection area, missing detections,\...). The aim of this paper is threefold: First, after having presented the level of details that can be reached with a network of isolated detectors we present how we modelled Brisbane's network, keeping only the information valuable for the retrieval of trip information. Second, we give an overview of the issues inherent to the Bluetooth technology and we propose a method for retrieving the itineraries of the individual Bluetooth vehicles. Last, through a comparison with Brisbane Transport Strategic Model results, we highlight the opportunities and the limits of Bluetooth detectors networks. The aim of this paper is twofold. We first give a comprehensive overview of the aforementioned issues. Further, we propose a methodology that can be followed, in order to cleanse, correct and aggregate Bluetooth data. We postulate that the methods introduced by this paper are the first crucial steps that need to be followed in order to compute accurate Origin-Destination matrices in urban road networks.

The eternal return of teaching in the time of the corporation

This article addresses the new conditions under which teachers are making the choice to teach. Our core contention is that the reorganisation of schools according to the logic of the corporation, as described in Deleuze's ‘Postscript’, is changing the flows and forces on the primary surface of ‘the classroom’. These changes block the usual movements of teaching to discipline, normalise and individualise, which was the role of the school as precursor to the factory. Blocked from repeating, or returning, teaching as it has always been done, teachers must actively re-will to teach; teachers cannot use order words to name themselves and direct flows and forces as they have usually been done. While many choices to teach will be undertaken, the most popular being that of choosing to teach toward the corporation, the repetition of teaching toward enclosed spaces becomes less compelling. Like Nietzsche's Zarathustra, teachers, who have the courage to actively choose, face a new dawn in which teaching cannot be what it once was. In that moment they must choose to repeat that choice an infinite number of times, the choice of eternal return, and it is from here that new times might begin.

Three medieval buildings in the port of Ardglass, Co Down

Three buildings in what is now a small port in Ardglass, Co. Down are connected by their location on the ridge overlooking the harbour and quay. Because of the Irish vernacular style related to tower houses they have all been called castles, but analysis shows that they were originally more commercial in their purpose. The largest of the buildings is identified as a line of shops. The building adjacent to that was possibly used as a warehouse or communal hall, while the third building appears to have been used as a watch tower for the port. As such they relate to other commercial buildings found in late medieval Irish towns, notably Kilmallock, Co. Limerick.

By Laws of the Corporation of the Town of Welland, 1878 [fragment]

The fragment appears to be part of a larger group of bylaws for the Town of Welland, 1878. The fragment includes bylaws Cap. I and Cap. II. Cap. I is a bylaw appointing auditors for the town for the year 1878. Due to paper loss only a portion of the title of the Cap. II bylaw is extent but appears to be a bylaw appointing a Hey…….trustee for the town. Welland was incorporated in 1858 as a town and became a city in 1917.
