The Virtual Interactive Relationship Between BIM Project Teams: Effective Communication to aid Collaboration in the Design Process

Building Information Modelling (BIM) provides a shared source of information about a built asset, which creates a collaborative virtual environment for project teams. Literature suggests that to collaborate efficiently, the relationship between the project team is based on sympathy, obligation, trust and rapport. Communication increases in importance when working collaboratively but effective communication can only be achieved when the stakeholders are willing to act, react, listen and share information. Case study research and interviews with Architecture, Engineering and Construction (AEC) industry experts suggest that synchronous face-to-face communication is project teams’ preferred method, allowing teams to socialise and build rapport, accelerating the creation of trust between the stakeholders. However, virtual unified communication platforms are a close second-preferred option for communication between the teams. Effective methods for virtual communication in professional practice, such as virtual collaboration environments (CVE), that build trust and achieve similar spontaneous responses as face-to-face communication, are necessary to face the global challenges and can be achieved with the right people, processes and technology. This research paper investigates current industry methods for virtual communication within BIM projects and explores the suitability of avatar interaction in a collaborative virtual environment as an alternative to face-to-face communication to enhance collaboration between design teams’ professional practice on a project. Hence, this paper presents comparisons between the effectiveness of these communication methods within construction design teams with results of further experiments conducted to test recommendations for more efficient methods for virtual communication to add value in the workplace between design teams.

The Big BIM battle: BIM adoption in the UK for large and small companies

As BIM adoption continues, the goal of a totally collaborative model with multiple contributors is attainable. Many initiatives such as the 2016 UK government level 2 BIM deadline are putting pressure on the construction industry to speed up the changeover. Clients and collaborators have higher expectations of using digital 3D models to communicate design ideas and solve practical problems. Contractors and clients are benefitting from cost saving scheduling and clash detection offered by BIM. Effective collaboration on the project will also give speed and efficiency gains. Despite this, many businesses of varying sizes are still having problems. The cost of the software and the training provides an obvious barrier for micro-enterprises and could explain a delay in adoption. Many studies have looked at these problems faced by SME and micro-enterprises. Larger companies have different problems. The efforts made by government to encourage them are quite comprehensive, but is anything being done to help smaller sectors and keep the industry cohesive? This limited study examines several companies of varying size and varying project type: architectural design businesses, main contractor, structural engineer and building consultancy. The study examines the barriers to a truly collaborative BIM workflow facing different specialities on a larger project and a contrasting small/medium project. The findings will establish that different barriers for each sector are actually pushing further apart, thus potentially creating a BIM-only construction elite, leaving the small companies remaining on 2D based drawing.

Implementation Feasibility of a Digital Nervous System for the Construction Industry: For Efficient and Effective Information Management across the Project Lifecycle

The construction industry has long been considered as highly fragmented and non-collaborative industry. This fragmentation sprouted from complex and unstructured traditional coordination processes and information exchanges amongst all parties involved in a construction project. This nature coupled with risk and uncertainty has pushed clients and their supply chain to search for new ways of improving their business process to deliver better quality and high performing product. This research will closely investigate the need to implement a Digital Nervous System (DNS), analogous to a biological nervous system, on the flow and management of digital information across the project lifecycle. This will be through direct examination of the key processes and information produced in a construction project and how a DNS can provide a well-integrated flow of digital information throughout the project lifecycle. This research will also investigate how a DNS can create a tight digital feedback loop that enables the organisation to sense, react and adapt to changing project conditions. A Digital Nervous System is a digital infrastructure that provides a well-integrated flow of digital information to the right part of the organisation at the right time. It provides the organisation with the relevant and up-to-date information it needs, for critical project issues, to aid in near real-time decision-making. Previous literature review and survey questionnaires were used in this research to collect and analyse data about information management problems of the industry – e.g. disruption and discontinuity of digital information flow due to interoperability issues, disintegration/fragmentation of the adopted digital solutions and paper-based transactions. Results analysis revealed efficient and effective information management requires the creation and implementation of a DNS.

Intelligent Decision-Making System Frameworks for a Digital Plan of Work: A Theoretical Investigation for the Construction Industry

The construction industry is characterised by fragmentation and suffers from lack of collaboration, often adopting adversarial working practices to achieve deliverables. For the UK Government and construction industry, BIM is a game changer aiming to rectify this fragmentation and promote collaboration. However it has become clear that there is an essential need to have better controls and definitions of both data deliverables and data classification. Traditional methods and techniques for collating and inputting data have shown to be time consuming and provide little to improve or add value to the overall task of improving deliverables. Hence arose the need in the industry to develop a Digital Plan of Work (DPoW) toolkit that would aid the decision making process, providing the required control over the project workflows and data deliverables, and enabling better collaboration through transparency of need and delivery. The specification for the existing Digital Plan of Work (DPoW) was to be, an industry standard method of describing geometric, requirements and data deliveries at key stages of the project cycle, with the addition of a structured and standardised information classification system. However surveys and interviews conducted within this research indicate that the current DPoW resembles a digitised version of the pre-existing plans of work and does not push towards the data enriched decision-making abilities that advancements in technology now offer. A Digital Framework is not simply the digitisation of current or historic standard methods and procedures, it is a new intelligent driven digital system that uses new tools, processes, procedures and work flows to eradicate waste and increase efficiency. In addition to reporting on conducted surveys above, this research paper will present a theoretical investigation into usage of Intelligent Decision Support Systems within a digital plan of work framework. Furthermore this paper will present findings on the suitability to utilise advancements in intelligent decision-making system frameworks and Artificial Intelligence for a UK BIM Framework. This should form the foundations of decision-making for projects implemented at BIM level 2. The gap identified in this paper is that the current digital toolkit does not incorporate the intelligent characteristics available in other industries through advancements in technology and collation of vast amounts of data that a digital plan of work framework could have access to and begin to develop, learn and adapt for decision-making through the live interaction of project stakeholders.

Structural Analysis with ANSYS on Stone Constructions in the Historical Spanish Heritage

According to the importance of rehabilitation and recovery of Architectural Heritage in the live of people, this paper is aimed to strengthen the traditional methods of stone vaults calculation taking advantage of the technological characteristics of the powerful program ANSYS Workbench. As an example of this, it could find out the possible pathologies that could arise during the construction history of the building. To limit this research, the upper vault of the main chapel of the Santiago parish church in Orihuela -Alicante- is selected as a reference which is a Jeronimo Quijano´s important building work in the XVI century in the Renaissance. Moreover, it is an innovative stone masonry vault that consists of 8 double intercrossed arches with each other and braced by severies. During the seventeenth century there was a lantern in the central cap and it is unknown why it was removed. Its construction could justify the original constructive solution with intercrossed arches that freed the center to create a more enlightened and comfortable presbytery. By similarity with other Quijano’s works, it is considered a small lantern drilling the central spherical cap. It is proposed to carry out a comparative study of it with different architectural solutions from the same period and based on several common parameters such as: a vault of square plant with spherical surround, intercrossed arches, a possible lantern, the dimension of the permitted space, similar states of loads and compact limestone masonry. The three solutions are mainly differentiated by their size and the type of lantern and its comparison lets us know which one is the most resistant and stable. The other two building works maintain some connection with the Quijano's professional scope. It has selected the particular case of the Communion chapel of the Basilica in Elche (a large prismatic lantern with a large cylindrical drum that starts from the own arches and an upper hemispherical dome), for its conservation, its proximity to Orihuela and its implementation during the century XVIII. Finally, a significant Dome Spanish Renaissance complete the selection: a cross vault of the Benavides Chapel of the Saint Francisco Convent in Baeza - Jaén-, designed by Andres of Vandelvira in the sixteenth century (a large hemispherical dome that starts from the own arcs). To simplify the calculation and standardize the work that have to be contrasted, all of them were considered with some similar characteristics: 30 cm constant thickness, the intercrossed arches were specifically analyzed and had identical loads, Young's modulus and Poisson's ratio. Regarding the calculation solutions, in general terms, the compressive stresses predominate, influencing on it the joint collaboration of the filling material on the vault, the vault itself, the thick side walls, the buttresses and the top cover weight . In addition, the three solutions are suitable, being the Orihuela one the safest and the Baeza one the riskiest for its large dimensions. Thus, the idea of intercrossed arches with suitable thickness would allow carry out the heaviest lantern and this would confirm it as a Renaissance architectural typology built in stone.

"Fit Cradle of the Reviving Art": An inquiry into the the Evolving Material Reality of the Murals in the Camposanto of Pisa from the Perspective of their British Reception from the 17th to the 19th century

The Camposanto of Pisa is an extraordinarily complex and evocative monument, which has captured the imagination of pilgrims, both religious and secular, for centuries. The late Medieval and early Renaissance wall paintings that line the perimeter of the portico surrounding a vast inner courtyard, are unparalleled in early Italian art, not only for their striking variety of composition and narrative complexity, but also for the sheer grandeur of their proportion. However, the passage of time has scarred the structure of the Camposanto and inflicted terrible damage on its wall paintings. This thesis explores the material reality of the Camposanto as experienced over three centuries through the eyes of British travelers. In order to situate the Camposanto mural cycle within an historical and cultural context, the first chapter provides an overview of the construction and decoration of the monument. Notably, Giorgio Vasari (1511-1574), the Italian Humanist often recognized as the father of art history, included numerous descriptions of the Camposanto murals in his highly influential text Vite de' più eccellenti pittori, scultori, ed architettori. Accordingly, the second chapter provides an analysis of Vasari’s descriptions and reflects upon the influence that the Renaissance author may have had upon the subsequent British reception of the Camposanto murals. The third chapter utilizes three centuries of travel writing in order to investigate the aesthetic impact of the Camposanto mural cycle upon British tourists from the seventeenth through to the nineteenth century.

The Catholic Identity of Malta after Ten Years of Membership in the European Union: Challenges and Prospects. Occasional Paper 2/2014

Introduction. Ten years have elapsed since Malta’s accession in the European Union. One can still recall vividly the intense and acrimonious campaign prior to the membership referendum and the ensuing electoral victory that confirmed the Nationalist Party (PN) in power under the leadership of Edward Fenech Adami in 2003. In both cases the Maltese voted in favour of entry into the EU. During both exercises in democracy the Maltese were exposed to the rhetoric of both prophets of doom and prophets of plenty. For the former accession meant a loss of national and territorial independence, for the latter it meant the beginning of opportunity for all and, in some cases, the answer to all of Malta’s woes. Now, ten years later, a further appraisal of Malta’s membership and place in the European Union is called for. The purpose of this paper, however, is to reflect upon how this membership has affected the Roman Catholic Church in Malta and what prospects lie ahead for the Catholic community within Maltese society that remains in a state of constant flux on both the social and the religious level. It traces the major events that have accelerated the transformation of Malta into a secular society. The paper describes how these events, together with pressures that are being brought to bear by secular movements upon Maltese society, are profoundly affecting its Catholic identity and redrawing its moral landscape. It also discusses ways and means by which the Catholic Church in Malta can address these challenges and contribute towards the construction of a more humane Maltese society. In order to achieve this, it must first and foremost remain a coherent witness of a faith that is forever alive, dynamic and relevant.

Before the parliamentary elections in Ukraine. OSW Commentary No. 149, 15.10.2014

The parliamentary elections to be held in Ukraine on 26 October will bring about deep changes in the political composition of the Verkhovna Rada, Ukraine’s parliament. It is very probable that after the elections only one or two of the five parties which are represented in the parliament today will remain, and the leading positions will be taken by groupings who were still considered marginal a year ago. The Petro Poroshenko Bloc, a party which according to polls can count on victory, did not exist a year ago and today still remains in the construction phase. It is likely that around two-thirds of the newly elected deputies will be people with no parliamentary or even no political experience. On the one hand, this may be a strong impetus to revival; but on the other the lack of experience of most of the parliamentarians may be a problem. Another source of potential problems may be the process of consolidating the internally unstable political parties which have emerged during the electoral campaign. All of the parties which will count in the upcoming elections have a pro-European programme. It is probable that the numerous supporters of an anti-Western orientation (although not necessarily a pro-Russian orientation, as recent events have shown) will be represented by very few deputies elected in single-mandate constituencies. On the one hand, this homogeneity within the Rada will facilitate the country’s reforms, including work on the new constitution, while on the other it might be a subject of permanent criticism by Moscow and its Ukrainian representatives. The elections will take place in the conditions of a growing wave of social disappointment and ongoing military actions in the eastern part of the country. Nevertheless, it can be expected that the vote will be held without any major disturbances, and its course will be transparent and fair.

At any price: Russia is embarking on the construction of South Stream. OSW Commentary No. 98, 2012-12-07

Gazprom is determined to continue its efforts to build the South Stream gas pipeline regardless of the slump on the European gas market and the fact that there is sufficient capacity already in the existing transport infrastructure. The official inauguration of the maritime section of South Stream was held on 7 December this year, but the construction itself will commence in 2014. The agreements concluded so far, both intergovernmental and between corporations, are necessary for the launch of the construction of the new pipeline, but still do not guarantee that the project will be completed on time. First of all, some legal problems have yet to be resolved, such as the evaluation of the compliance of the planned actions with the ‘third energy package’ or the fact that ecological surveys required under European law need to be carried out. Secondly, given the present situation on the European gas market and medium-term forecasts, the high cost of implementation of this project and the maintenance expenses of existing pipelines – which are not being used to full capacity – the new project seems to be unfeasible. However, Gazprom’s determination in its efforts to build the pipeline proves that Russia is ready to take a high economic risk to maintain its dominant position on the European gas supply market; it will restrict the possibilities of alternative infrastructural projects being implemented (above all, the EU’s Southern Corridor) and use the construction of new pipelines as an instrument of political pressure on the present transit countries (especially Ukraine).

Bulgarian-Russian games in the energy sector: an outcome is getting closer. OSW Commentary No. 61, 2011-10-5

Bulgaria and Russia are entering the final phase of setting the conditions of their co-operation in the energy sector. A new gas contract is being negotiated because the currently applicable agreements will have expired by the end of 2012. The fate of two major energy projects – whose implementation depends on good co-operation between Sofia and Moscow: the Burgas– –Alexandroupolis oil pipeline and the construction of a Bulgarian nuclear power plant in Belene with Russian participation – is currently being decided. Another issue ever-present on the agenda is the future of the South Stream gas pipeline promoted by Russia, which is to run through Bulgarian territory. The outcome of all the aforementioned discussions and negotiations will determine for years the model of Bulgarian-Russian relations and may strongly affect the shape of the oil, gas and electricity markets in South-Eastern Europe.

An Exercise in Legal Honesty: Re-writing the Court of Justice and the Bundesverfassungsgericht. IHS Political Science Series No. 136, February 2014

At a time of crisis – a true state of emergency – both the Court of Justice of the European Union and the German Federal Constitutional Court have failed the rule of law in Europe. Worse still, in their evaluation of the ersatz crisis law, which has been developed in response to financial and sovereign debt crises, both courts have undermined constitutionality throughout Europe. Each jurisdiction has been implicated within the techocratisation of democratic process. Each Court has contributed to an incremental process of the undermining of the political subjectivity of European Citizens. The results are depressing for lawyers who are still attached to notions of constitutionality. Yet, we must also ask whether the Courts could have acted otherwise. Given the original flaws in the construction of Economic and Monetary Union, as well as the politically pre-emptive constraints imposed by global financial markets, each Court might thus be argued to have been forced to suspend immediate legality in a longer term effort to secure the character of the legal jurisdiction as a whole. Crisis can and does defeat the law. Nevertheless, what continues to disturb is the failure of law in Europe to open up any perspective for a return to normal constitutionality post crisis, as well as its apparent inability to give proper and honest consideration to the hardship now being experienced by millions of Europeans within crisis. This contribution accordingly seeks to reimagine each Judgment in a language of legal honesty. Above all, this contribution seeks to suggest a new form of post-national constitutional language; a language which takes as its primary function, proper protection of democratic process against the ever encroaching powers of a post-national executive power. This contribution forms a part of an on-going effort to identify a new basis for the legitimacy of European Law, conducted jointly and severally with Christian Joerges, University of Bremen and Hertie School of Government, Berlin. Differences do remain in our theoretical positions; hence this individual essay. Nevertheless, the congruence between pluralist and conflict of law approaches to the topic are also readily apparent. See, for example, Everson & Joerges (2013).

The nuclear safety framework in the European Union after Fukushima. Egmont Paper No. 73, December 2014

Summary. On 11 March 2011, a devastating earthquake struck Japan and caused a major nuclear accident at the Fukushima Daiichi nuclear plant. The disaster confirmed that nuclear reactors must be protected even against accidents that have been assessed as highly unlikely. It also revealed a well-known catalogue of problems: faulty design, insufficient back-up systems, human error, inadequate contingency plans, and poor communications. The catastrophe triggered the rapid launch of a major re-examination of nuclear reactor security in Europe. It also stopped in its tracks what had appeared to be a ‘nuclear renaissance’, both in Europe and globally, especially in the emerging countries. Under the accumulated pressure of rising demand and climate warming, many new nuclear projects had been proposed. Since 2011 there has been more ambivalence, especially in Europe. Some Member States have even decided to abandon the nuclear sector altogether. This Egmont Paper aims to examine the reactions of the EU regarding nuclear safety since 2011. Firstly, a general description of the nuclear sector in Europe is provided. The nuclear production of electricity currently employs around 500,000 people, including those working in the supply chain. It generates approximately €70 billion per year. It provides roughly 30% of the electricity consumed in the EU. At the end of 2013, there were 131 nuclear power reactors active in the EU, located in 14 countries. Four new reactors are under construction in France, Slovakia and Finland. Secondly, this paper will present the Euratom legal framework regarding nuclear safety. The European Atomic Energy Community (EAEC or Euratom) Treaty was signed in 1957, and somewhat obscured by the European Economic Community (EEC) Treaty. It was a more classical treaty, establishing institutions with limited powers. Its development remained relatively modest until the Chernobyl catastrophe, which provoked many initiatives. The most important was the final adoption of the Nuclear Safety Directive 2009/71. Thirdly, the general symbiosis between Euratom and the International Atomic Energy Agency (IAEA) will be explained. Fourthly, the paper analyses the initiatives taken by the EU in the wake of the Fukushima catastrophe. These initiatives are centred around the famous ‘stress tests’. Fifthly, the most important legal change brought about by this event was the revision of Directive 2009/71. Directive 2014/87 has been adopted quite rapidly, and has deepened in various ways the role of the EU in nuclear safety. It has reinforced the role and effective independence of the national regulatory authorities. It has enhanced transparency on nuclear safety matters. It has strengthened principles, and introduced new general nuclear safety objectives and requirements, addressing specific technical issues across the entire life cycle of nuclear installations, and in particular, nuclear power plants. It has extended monitoring and the exchange of experiences by establishing a European system of peer reviews. Finally, it has established a mechanism for developing EU-wide harmonized nuclear safety guidelines. In spite of these various improvements, Directive 2014/87 Euratom still reflects the ambiguity of the Euratom system in general, and especially in the field of nuclear safety. The use of nuclear energy remains controversial among Member States. Some of them remain adamantly in favour, others against or ambivalent. The intervention of the EAEC institutions remains sensitive. The use of the traditional Community method remains limited. The peer review method remains a very peculiar mechanism that deserves more attention.

e_LIPID: Characterisation of the Lipid Profile in the Portuguese Population

AIM: Cardiovascular disease (CVD), particularly coronary heart disease and stroke, are the leading cause of morbidity and mortality worldwide. The common forms of CVD have a complex etiology in which interactions between multiple genetic and environmental factors play an important role. Dyslipidaemia is one of many independent cardiovascular risk factors that have been identified for CVD, and its correct identification is of great importance in order to implement specific interventions, especially for CVD prevention. The aim of this study was the construction of population specific lipid percentiles and the to present the characterization of the dyslipidaemia in the Portuguese population.

Sediment constituents and quartz in the sand-sized fraction, West Florida slope and Mississippi Fan sediments

The interval between 488.2 and 513.7 m below seafloor at Deep Sea Drilling Project (DSDP) Site 615 is interpreted as a single carbonate gravity-flow deposit. The deposit has characteristics of both a debris flow and a high-density turbidity current. Comparison of the sedimentary constituents in 15 samples from this site with samples from 26 core tops from the upper West Florida continental slope and eastern Mississippi Fan shows many similarities. Shallow-water indicators, such as mollusk and echinoid fragments, occur in both suites of samples. The West Florida continental margin, therefore, is a potential provenance area. The Yucatan slope is also a possible source, but data from it are limited. The recognition of carbonate gravity-flow deposits intercalated within the Mississippi Fan refines our understanding of Pleistocene sedimentation within the Gulf basin. Deposition in the deep Gulf is dominated by the construction of the Mississippi Fan. However, this marine terrigenous depocenter is located between two large carbonate depocenters, the West Florida continental margin on the east and the Yucatan peninsula on the southwest. Periodically, the carbonate slope in these two regions fails, injecting carbonate gravity flows into the accreting terrigenous deep-sea fan.

Diplomatic history of the Panama Canal. Correspondence relating to the negotiation and application of certain treaties on the subject of the construction of an interoceanic canal, and accompanying papers.
