Fieldwork in a major construction programme is used to examine what is meant by professionalism where large integrated digital systems are used to design, deliver and maintain buildings and infrastructure. The increasing 'professionalization' of the client is found to change professional roles and interactions in project delivery. New technologies for approvals and workflow monitoring are associated with new occupational groups; new kinds of professional accountability; and a greater integration across professional roles. Further conflicts also arise, where occupational groups have different understandings of project deliverables and how they are competently achieved. The preliminary findings of the study are important for an increasing policy focus on shareable data, in order for building owners and operators to improve the cost, value, handover and operation of complex buildings and infrastructure.. However, it will also have an impact on wider public decision making processes, professional autonomy, expertise and interdependence. These findings are considered in relation to extant literatures, which problematize the idea of professionalism; and in light of this ongoing shift from drawings to shareable data as deliverables. The implications for ethics in established professions and other occupational groups are discussed; directions are suggested for further scholarship on professionalism in digitallymediated project work to improve practices which will better serve society.

The design process requires coordination between professions that have different ways of seeing.Using ethnographic data from a building project, this paper explores how architects and engineers mobilize visual objects to coordinate their professional visions around a design issue. The findings articulate the visual practices whereby design professionals move from a fragmented towards a shared professional vision. In this move, they cease looking at the design issue from within their disciplinary perspective, and begin taking inspiration from each other's. They further adjust the emergent shared professional vision, by iteratively narrowing and broadening its focus. The paper contributes to the practice perspective in design studies, explaining how different ways of seeing are coordinated through practical engagement with visual objects.

From fieldwork conducted ahead of the London Olympic Games, we develop new understanding of how organizations hand over digital data from the project to operations. Prior research explains how practitioners negotiate meaning across boundaries in ongoing work. However, it gives little attention to hand-over, where one group disengages as another engages. We use the analogy of the baton pass in a relay race to articulate how hand-over requires attention to sequence, timing, passing technique and communication within a time-constrained window of opportunity. In our case study, the project delivery team transfer responsibility for sports venues and other facilities, and their associated digital data, to Games operators. We show how delivery professionals both project the nature of future work; and probe how meanings will be interpreted. They seek to extend the window to discuss and negotiate meaning with operators. Our study contributes to research on engineering projects and on the coordination of knowledge work by articulating the baton pass, window of opportunity and projection and probing activities involved in hand-over. Understanding and improving the hand-over of digital data from the project to operations is important to enable owners and operators to better manage built infrastructure. ARTICLE HISTORY

Many complaints about indoor conditions are related to unsatisfactory thermal environments. Most research on Thermal Comfort (TC) considered physical parameters for settings and users yet marginalized the influence of user's psychological aspects in the process of thermal sensation. Immersive Virtual Reality (VR) has been used in the built environment to simulate real scenarios. This research examines the effect of mood states on human evaluation of the thermal environment in virtual settings. Forty-four university students from Jordan participated. The experiment followed the "Experimental Design Method" using thermally controlled chamber and TC evaluation using psychological responses developed by Fanger. The participants completed the PANAS-X pre-mood test before watching a video that targeted eliciting predetermined mood states; anger and happiness. The participants were then immersed in two virtual environments and asked to complete ASHRAE 7-point scale of TC. General Linear model was used to analyse the data. The results revealed a relationship between TC, mood state and quality of the indoor environment. Humans' judgment on TC is a variable mental reaction. The research presents differences between the evaluation of angry and happy people to their thermal environments. This study expands research on the indoor environment quality and develops TC evaluation strategies.

PurposeIndustrial heritage is considered an essential part of cultural heritage in the world. This heritage suffers from continued marginalisation in the Arab world, particularly in Jordan, where many industrial heritage sites have not been protected or studied well due to the lack of a clear definition of cultural heritage. Most of these sites, built in the 20th century, are gradually disappearing or scheduled for demolition. This paper explores the de-industrialisation discourse and the loss of modern industrial heritage in the Arab world, especially in Jordan.Design/methodology/approachThis research investigates the modern industrial heritage in Jordan as a case study in the Arab world. A comprehensive understanding of the industrial heritage has been obtained by adopting a case study approach and using a reconnaissance survey of potential industrial heritage sites in Jordan.FindingsSeven categories were used in the analysis of the de-industrialisation phenomenon of heritage sites: ownership, location, design and types; structure, significance, deterioration and physical condition and conservation attempts and alterations. Three main approaches to industrial heritage were identified: demolition, occasional maintenance and rare examples of conservation and adaptive reuse.Research limitations/implicationsThis study sheds light on the ownership issue of industrial structures in Jordan and invites policymakers, relevant authorities, private organisations and the public to consider the challenges and impact of de-industrialisation of such sites.Originality/valueThis research raises awareness of the de-industrialisation discourse, and highlights the value of industrial architecture dating back to the modernity period, which was short-lived in Jordan. It also calls for serious consideration of these sites to support sustainable development in the Arab World.
