Notes on ‘open systems’ in building technology

Careful reading of the literature, in light of recent developments in theory and practice in building, suggests that systems theory as understood in the field of building technology is ready for updating. These notes support the movement in ‘systems’ discussions toward an explicit recognition of the concept of control—or the action of assembling or transforming elements in the staged assembly of buildings. The notes suggest that technical issues, while critical, are insufficient to explain innovation, failure or other aspects of change in technical systems for building. A more adequate understanding is, it is argued, necessarily linked to questions of control.     

Site managers’ daily work and the uses of building information modelling in construction site management

The use of building information modelling (BIM) and related software tools is increasingly expanding in the work of site managers in construction projects. The early uses of BIM in the actual tasks of site managers are explored by examining the utilization of BIM in their work and the challenges in the deployment of the new digital tools for traditional project collaboration. The ethnographic method of the study consists of shadowing the site managers’ work. The site managers actively used BIM and found it beneficial for their daily work. However, the use of BIM in construction sites is still limited because only a few managers have the competence to use BIM software tools, mobile tools are lacking, and the information content of the models needed for construction work is insufficient.     

Between ‘true believers’ and operational experts: UNESCO architects and school building in post-colonial Africa

Following decolonisation in the late 1950s, Cold War competitiveness and economic globalisation prompted old and new foreign powers to invest in the development of Africa. By means of building and urban planning, they sought to transmit their specific models of modernisation to the continent. Architects from divergent contexts and backgrounds embraced this opportunity to transfer their expertise to Africa, in particular through development aid organisations. This paper will shed light on the expert(ise)s that were exported to, and generated within, Africa in the 1960s and 1970s through one particular international aid agency, namely UNESCO. The focus will be on the organisation's activity in the field of school building, a crucial sector of development in Africa following the independence of former colonies across the continent. Through this agency, a transnational network of expert-architects with highly divergent backgrounds was generated. Taking UNESCO as a starting point, we identify a number of such globally operating architects who had a crucial impact on the design and construction of educational facilities, but remain unstudied to date. By an analysis of their work the paper reveals the design knowledge that was generated and the building expertise that circulated through UNESCO in Africa, while simultaneously untangling the complex networks and mechanisms behind this unique architecture production.     

Materials in Germany’s domestic building stock: calculation model and uncertainties

Building stocks are the dominant consumers of resources within national economies. Correspondingly, there is high demand for improved knowledge of material stocks and flows in the built environment. Material flow analysis is well suited to meet this demand. Although numerous studies have been conducted on this topic over recent years, these frequently lack applicability and transferability due to insufficient documentation or treatment of uncertainties. A new approach is presented here to calculate material stocks and flows for domestic buildings using the example of multi-family housing (MFH) in Germany. The approach is critically examined to determine its validity. The calculation process involves four steps: (1) building types are classified according to building age; (2) highly specific material composition indicators (MCIs) are calculated for the respective building types; (3) the total material stock as well as inflows and outflows are derived from the total floor space of Germany’s MFH; and (4) validity tests are performed to quantify uncertainties. The main results are age-based MCIs for MFH, the total material mass as well as quantitative information on parameter- and model-related uncertainties. Conclusions are drawn on the validity of results, the scalability and applicability of the model and its implementation, along with potential model refinements.     

Landlords and Tenants in Informal ‘Colonia’ Settlements in Texas

Owner-occupied self-help and self-managed housing has been the norm in colonias—low-income informal settlements along the US–Mexico border—so scholarly treatment of renting in these settlements has been limited. This article adds to the scant literature on this topic and is the first to document the nature of renting in multi-unit rental complexes in colonias. The article explores the characteristics of landlords and their motivations for pursuing landlordism by drawing upon key informant interviews with owners of rental property. The results of 47 surveys conducted with households in multi-unit complexes throughout 18 colonias in Starr County, as well as the results from intensive, conversational case study interviews with selected households, are used to illustrate the precarious and informal nature of renting in colonias and provide a limited portrayal of the housing preferences and needs of renters. The article ends with an evaluation of the policy implications of these findings.     

Designing a ‘green’ building: expanding ambitions through social learning

The process of creating a specific building – Miljøbygget in Trondheim, Norway – is analyzed in order to understand how the project team's ambitions expanded to embrace ‘green’ issues and create new targets. The decisions and roles of key actors are investigated regarding these goals and criteria. The analysis draws on two concepts. First, translation theory is used to highlight the potential role of new knowledge or technology that originates outside of the project. Second, the concept of social learning is employed to understand the process of expanding ambitions, developing goals and criteria within the project, and how this is related to the collective exploration, discovery and analysis of new practices. The wider implications are considered with respect to innovation in the construction industry. The project's initial moderate energy efficiency ambition was transformed, first into stricter energy efficiency goals, then into broader environmental aims. The resulting innovation is an ambition-enhancing, experience-based and enthusiasm-driven process of social learning in the project team, marked by interpersonal trust, including trust regarding competence and contractual relations. Translation efforts were also found to be important for bringing new knowledge into the project. The conclusion discusses some policy implications.     

An examination of the ‘rule of law’ and ‘justice’ implications in Online Dispute Resolution in construction projects

This paper examines the ‘rule of law’ and ‘justice’ implications of using Online Dispute Resolution (ODR) platforms as technology-mediated interfaces for small claim dispute resolution in construction projects. Data is obtained from a questionnaire survey of construction stakeholders, administered using direct non-random sampling of professional contacts with the authors. Data is analysed using SAS 9.4 (SAS Institute, Cary, NC) on a Windows 7 platform. Surprisingly, study findings do not suggest any ‘rule of law’ and ‘justice’ implications for small claim ODR. Tentatively, this conclusion supports wider use of ODR. The originality of the study is that although there is considerable academic and practitioner interest in various alternative forms of dispute resolution (ADR), both practitioner use and academic study of ODR remain sparse. Thus, this study serves as a foundation for further empirical exploration of ODR as a nascent component of ADR.     

‘Ma and Pa’ Landlords and the ‘Risky’ Tenant: Discourses in the New Zealand Private Rental Sector

Social constructions of what it means to let and rent housing are revealed in language and are intimately tied to housing outcomes for both landlords and tenants. This paper is concerned with the socially constructed identities of landlords and tenants in the private rental sector and how these are revealed in language. Fairclough's methods of discourse analysis coupled with Habermas' ideal speech situation and theory of communicative action are used to form an analytical framework for examining public debate and discourse on the private rental sector in New Zealand. It is argued that current discourses about tenants and landlords are the result of public debate and stereotypes that have failed to incorporate the experiences of tenants, and further that these stereotypes conceal the multiplicity of identities and motivations for behaviour of both landlords and tenants.     

Distinguishing between green building occupants’ reasoned and unplanned behaviours

Several frameworks incorporate social and psychological elements of environmentally significant behaviour, and most assume cognitive and deliberate decision-making. Household energy consumption behaviours, however, span a spectrum from reasoned and deliberate to unplanned and automatic. The aim of this paper is to advance knowledge of reasoned and unplanned behaviours in the context of pro-environmental action. Using results of a survey administered to occupants of an urban residential green building, this study explores five household consumption behaviours and tests the hypothesis that unplanned behaviours will be poorly predicted by a reasoned, values-based behavioural framework. Using path analyses, variables in a values-based framework are used to predict surveyed behaviours. Findings indicate that behaviours hypothesized to be unplanned were not well predicted by the values-based framework. The framework successfully predicted what was hypothesized to be a fully reasoned behaviour. Three potential reasons are discussed for the lack of prediction of some behaviours. A deeper understanding of how unplanned, automatic or habitual behaviours intervene in conservation intentions can help policy-makers and building designers better respond to influences of occupant behaviour on building performance.     

The difference of ‘being diverse’: City branding and multiculturalism in the ‘Leicester Model’

This city profile on Leicester focuses on the representation of ethnical diversity in city branding. Through a historical approach, the paper discusses how the local authorities have taken advantage of the arrival of different migration flows into the city, in order to redefine its post-industrial identity in terms of multiculturalism, tolerance and inclusivity. In so doing, the paper emphasises the combination of deliberate marketing communicative activities, the provision of services for attracting and retaining foreign businesses and the creation of an open urban milieu where various ethnic groups are free to express and celebrate their own cultures through festivals and events. The paper identifies the alignment between place communication and place ‘offerings’ development as the crucial element underpinning Leicester's model for multicultural cooperation and critically assesses the recent challenges that are being posed to the sustainment of a multicultural city image.     

Identification of landslide hazard and risk ‘hotspots’ in Europe

Landslides are a serious problem for humans and infrastructure in many parts of Europe. Experts know to a certain degree which parts of the continent are most exposed to landslide hazard. Nevertheless, neither the geographical location of previous landslide events nor knowledge of locations with high landslide hazard necessarily point out the areas with highest landslide risk. In addition, landslides often occur unexpectedly and the decisions on where investments should be made to manage and mitigate future events are based on the need to demonstrate action and political will. The goal of this study was to undertake a uniform and objective analysis of landslide hazard and risk for Europe. Two independent models, an expert-based or heuristic and a statistical model (logistic regression), were developed to assess the landslide hazard. Both models are based on applying an appropriate combination of the parameters representing susceptibility factors (slope, lithology, soil moisture, vegetation cover and other- factors if available) and triggering factors (extreme precipitation and seismicity). The weights of different susceptibility and triggering factors are calibrated to the information available in landslide inventories and physical processes. The analysis is based on uniform gridded data for Europe with a pixel resolution of roughly 30 m × 30 m. A validation of the two hazard models by organizations in Scotland, Italy, and Romania showed good agreement for shallow landslides and rockfalls, but the hazard models fail to cover areas with slow moving landslides. In general, the results from the two models agree well pointing out the same countries with the highest total and relative area exposed to landslides. Landslide risk was quantified by counting the number of exposed people and exposed kilometers of roads and railways in each country. This process was repeated for both models. The results show the highest relative exposure to landslides in small alpine countries such as Lichtenstein. In terms of total values on a national level, Italy scores highest in both the extent of exposed area and the number for exposed population. Again, results agree between the two models, but differences between the models are higher for the risk than for the hazard results. The analysis gives a good overview of the landslide hazard and risk hotspots in Europe and allows a simple ranking of areas where mitigation measures might be most effective.     

Towards a synergy between ‘content’ and ‘process’ in Dutch spatial planning: the Heuvelland case

Spatial planning in the Netherlands is shifting from regulatory toward more developmental modes of planning. This paper explores the background of these changes and discusses current approaches to developmental planning, especially in rural areas. It combines views reflected in planning theory with the accumulated experiences of a project in the southern part of the Netherlands, called Heuvelland. The Heuvelland project is aimed at the mobilisation of market parties for spatial developments. It is an attempt to circumvent the path-dependency in which many current spatial innovation projects get caught up, owing to established institutional planning and policy arrangements. We argue that in order to stimulate innovation and create a new economic base for rural spatial developments, new economic actors and new public–private structures and networks must be mobilised. We consider how this can be done, taking into account the importance of sustainable regional development.     

Between ‘Market’ and ‘Welfare’: Rent Restructuring Policy in the Housing Association Sector,England

This paper empirically evaluates the market and welfare impacts of rent restructuring policy in the housing association (RSL) sector. The focus is on the financial viability of housing associations in the north of England, the affordability problems of tenants in the south, and the changes of turnover rates of RSL tenancies that have resulted. Using data from the Regulatory and Statistical Returns and the CORE (COntinuous REcording) from 2001/02 to 2005/06, the analysis shows that the ‘market’ component of the rent formula plays a more substantial role in affecting the RSL rent levels despite the ‘welfare’ measures in the policy—the greater emphasis on local earnings, the restriction of annual rent increase and the imposition of rent ceilings. Given that social housing in England is essentially a residual mode of provision, it is argued that a more flexible approach in balancing these two conflicting principles in rent setting is needed.     

Growth and degradation in the Orient’s ‘Las Vegas’: issues of environment in Macau

This paper argues that the rapid growth of gambling‐related tourism and urban construction in Macau has given rise to serious environmental degradation. The major environmental issues include air quality, water supply, solid waste disposal, noise prevention, heritage conservation and environmental management. The author suggests that the government in Macau should refocus this city’s development direction and commit itself to sustainable development. At the policy‐making level, there are such urgent issues as integration of environmental, economic and urban planning with community participation in decision‐making; enhancement of environmental legislation and institutions; implementing vital measures to control of the numbers of visitors; developing a mass transport system; and protecting the city’s cultural heritage.     

‘Orthodox’ and ‘alternative’ explanations for the reduction of urban violence in Medellín,Colombia

In 2016, 43 of the 50 most dangerous cities in the world were located in Latin America. In reducing levels of urban violence and preventing future outbreaks, approaches developed in Western Europe and North America are the most influential and have been subjected to considerable testing in high-income urban environments.

This article focuses on Medellín, Colombia. By drawing from qualitative data collected in Medellín, the article scrutinises claims that the social urbanism policies caused the significant reduction in homicides. An alternative explanation for the reduction in homicides is then presented, focusing on the methods of the perpetrators of violence.     

Contractors’ perception of risk factors affecting cost overrun in building projects in Palestine

This study aims at identifying the risk factors affecting cost overrun in building construction projects in the West Bank in Palestine from contractors’ viewpoint. To do so, 31 contractors working on building construction completed a structured questionnaire survey. Forty factors were identified through a literature review. These factors were grouped into five groups: cost estimating, construction items, construction parties, environmental, and financing. The results indicated that the top five affecting factors are fluctuation in currency exchange rate, project financing, contract management, level of competitors, and cost of materials. The findings can support the government in improving the regulations to meet the construction market needs, owners in planning and designing and evaluating policy, contractors and managers in planning and taking external and internal risks when costing and scheduling contracts, consultants in applying comprehensive contract information, and workers in conducting their day-to-day activities. The results will fill an important research and practice gap.     

The chicken or the egg? building anglican churches and building congregations in a victorian london suburb

ABSTRACT

There was lively debate in the mid-Victorian Church of England as to whether it was more effective for the construction of physical church buildings to precede the formation of a new parish and congregation, or whether it was advisable instead for the human church to precede the material one. This article explores the realities on the ground through a case study of the four new churches built in the North London suburb of Finchley between the 1840s and the 1890s. Where the church before congregation strategy was modestly costed and efficiently executed, it could, as at Holy Trinity East Finchley (1846) and St. Paul's Long Lane (1886), enable the rapid growth of thriving congregations. However, at Christ Church North Finchley (1868), where the congregation came first, subsequent pastoral activity was hampered for many years by the financial demands of an unnecessarily expensive building. At All Saints Durham Road (1892), initial plans to set up a congregation in an “iron church” were frustrated due to large donations conditional on the immediate erection of a permanent church. In a context of strong competition from Nonconformity, the desire to make a strong material statement of presence in a community was understandable, but its long-term consequences for the Church's mission were ambivalent ones.     

‘Resilience thinking’ in transport planning

Resilience has been discussed in ecology for over 40 years. While some aspects of resilience have received attention in transport planning, there is no unified definition of resilience in transportation. To define resilience in transportation, I trace back to the origin of resilience in ecology with a view of revealing the essence of resilience thinking and its relevance to transport planning. Based on the fundamental concepts of engineering resilience and ecological resilience, I define ‘comprehensive resilience in transportation’ as the quality that leads to recovery, reliability and sustainability. Observing that previous work in resilience analysis in transportation has focussed on addressing engineering resilience rather than ecological resilience, I conclude that transformability has been generally overlooked and needs to be incorporated in the analysis framework for comprehensive resilience in transportation.
