189 A SIMULATION WITH NO PARTICIPANTS ONLY CO-FACULTY: USING SIMULATION FOR SYSTEMS INTEGRATION ON THE LARGE SCALE

The large-scale relocation of a paediatric hospital is a significant undertaking. New environments change the system, and ways of working must adapt to maintain quality healthcare. There are risks to patients and staff well-being, with high anxiety around change. There is evidence for the efficacy of simulation as a tool for safe training and rehearsal of staff and teams [1] but less so on such a large scale. Simulation for many is still perceived as a test of performance and a threat. We connected with the international simulation community to design a hospital-wide programme of Patient Environment Simulations for Systems Integration (PESSI). This paper outlines challenges in establishing buy-in from stakeholders and departments, developing a framework for implementation and our reflections on delivery of large-scale simulation activities to assist a hospital move.How can simulation-based methodology be used to support clinical departments on a large scale to adapt/integrate/prepare in moving to a brand-new hospital?Collaboration with authors of PEARLS for system integration use [1], using it as the main framework for delivery and structure of PESSI. Stages of delivery were: pre-phase work, system testing day, debrief/reflection and evaluation. Immediate feedback of enjoyment and learning was collated from all participants. Three-month post-move feedback is planned to review ongoing impact/behaviour change plus analysis of safety incidents.Pre-phase work involved meeting stakeholders and establishing aims of testing. Ward managers were key departmental links, meeting with members of PESSI to plan scenarios. System testing days involved familiarizing themselves with the environment, followed by ‘day in the life’ simulations with a representation of the whole team. All participants were called ‘co-faculty’ and knew exactly what would happen. Debrief involved facilitated conversations with the whole team describing reactions, and deeper analysis of the key events, with concerted efforts by facilitators to give a balanced approach of positives and challenges. A short report was given back to the department detailing the findings teams would need solutions to. Solutions from simulation were implemented prior to the move, increasing staff confidence, with many feeling PESSI played a major role in feeling prepared for the new site. The PESSI framework is being utilized in adult services and we hope to publish our methodology to share with the wider simulation community.

Systems Integration in Infrastructure Projects: Seven Lessons from Crossrail

We propose a systems integration model for the delivery of complex infrastructure projects. We argue that the client is ultimately accountable for systems integration in major projects, setting out the responsibilities to ensure that systems integration is successfully accomplished to achieve desired outcomes. From the Crossrail case, we draw seven lessons for clients, to: 1) manage programme delivery as an integration activity; 2) actively manage systems integration; 3) ensure authority to make decisions; 4) maintain configuration control; 5) plan for a lengthy testing and commissioning phase; 6) appreciate supply chain products may be part of unaligned global R&D and development programmes; and 7) do final integration only when there is something to integrate. Central to our argument is the idea that on such complex projects, the client cannot outsource systems integration and thus needs to recognize they retain accountability, though roles and responsibilities can be assigned to the delivery partner, supply chain, chief engineer and/or contracted systems integration firm. A key question for the client at the outset is how to distribute interface management and systems integration responsibilities while retaining accountability and oversight. Rather than managing through contracts, budgets and schedules, we suggest a changed approach with priority given to managing integration, and contracts, budgets and schedules that support and incentivise this.

The Suitability of Double-Layer Space Structures for Super-Tall Buildings: A Study from Structural and Building Systems Integration Perspectives

<p>As buildings rise higher, designers face two major issues. Firstly, how to design efficient structures to resist the lateral loads that impact so greatly on tall buildings. Secondly, how to effectively integrate building systems, which often consume large amounts of space in taller buildings and potentially detract from the building aesthetics. Double‐layer space structures have the potential to address these issues due to several beneficial design characteristics. As three‐dimensional structures, double‐layer space structures are rigid and structurally efficient. They can also integrate with other building systems by using the inherent structural cavities to accommodate services components and contribute a particular architectural aesthetic if their regular pattern is exposed. Double‐layer space structures have been used in long‐span structure buildings, but have yet to be applied as vertical structures for super‐tall buildings. Only two projects, proposed by Kahn and Tying, and Swenson, have applied double‐layer space structures as vertical structures in high‐rise buildings. However, they have not yet been executed and no literature has discussed the feasibility of the application of this structural system to supertall buildings. This situation leads to the research question; “Are double‐layer space structures suitable for super‐tall buildings?” To answer this question, a long‐term study with multidisciplinary knowledge, involving surveys of public opinion, and possibly real pilot projects would be required. This research focuses only on structural efficiency and systems integration as the initial step of the study of vertical double‐layer space structures in super‐tall buildings. The main objective of this research is to analyse the efficiency of this structural system, especially compared to other current tall structural systems. The second objective is to investigate to what extent these structures can integrate with other building systems as well as a discussion on advantages and disadvantages of the integration. The significance of this research is to provide initial scientific information for designers about the possibility of using double‐layer space structures as a structural system of super‐tall building. A research methodology including both quantitative and qualitative approaches is employed to measure the structural efficiency of vertical double‐layer space structures and to assess their potential to integrate with other building systems. This research covers structural aspects, building services systems including fire safety and approaches to energy efficiency, architectural integration, and construction. A quantitative approach by structural design and analysis, and comparison of double‐layer space structures with other structural systems is used to analyse structural efficiency. Case studies using the structural models of two 100‐storey double‐layer space structure buildings with different values of slenderness are designed and analysed using the computer software, ETABS. Other currently used structural systems, a bundled‐tube, a braced‐tube and a diagrid, are also designed using the same configuration and their structural analysis findings are compared to those of double‐layer space structures. Services systems, including HVAC, stairs and elevators, are also designed and integrated with the structure. The systems integration aspect of this research in double‐layer space structure buildings is analysed using a qualitative approach in three main steps. The first step is a review of relevant literature covering systems integration and current technologies in tall buildings. Based on this review, systems integration in double‐layer space structure buildings in general and the 100‐storey case study buildings in particular are explored using computer models. As the final step, the advantages and disadvantages of the systems integration in the designed case studies are discussed. These case studies are designed in order to represent current super‐tall buildings and recent technologies in high‐rise buildings. The structural models of 100‐storey buildings are relevant for buildings in the approximate range of 75 to 125 storeys or 300 to 500 metres high; the majority of current super‐tall buildings have been built in that range of heights. Recent technologies that are commonly used in super‐tall buildings, for example Centralised Air Handling and Localised Air Handling for HVAC system, double‐decking and sky lobbies for elevator system, and various façade systems, are adopted in these case studies. The aim is The Suitability of Double‐layer Space Structures for Super‐tall Buildings to investigate if double‐layer space structures can accommodate building components of current technologies. The results of this research show that double‐layer space structures are efficient where applied in super‐tall buildings when compared to other existing structural systems. Doublelayer space structures can also integrate with services components. The case study design shows how larger usable floor areas than those in typical tall buildings can be provided by positioning the majority of services and structural components within the space structure on the perimeter of the building. In terms of fire safety, positioning fire safety and egress systems in two different locations far apart, as proposed in this research, increases their reliability. Double‐layer space structures are highly redundant structures that enable loads to be transferred through other structural members if several structural members collapse. This advantage minimises the possibility of progressive collapse. The ability of double‐layer space structures to visually and physically integrate with architectural components and aspects like façade, interior space and building geometry in various ways is also explored. In terms of construction, simple connections and construction methods can be applied to double‐layer space structures leading to competitive construction costs. The research concludes by discussing the advantages and disadvantages of double‐layer space structures for super‐tall buildings and concludes that double‐layer space structures are indeed suitable for this application within the scope of this research. However, the study also recommends future research to address issues that are not covered in this research.</p>

Photovoltaic Systems Integration Rules and Restrictions in the Historic Buildings Architecture

Solar photovoltaic systems integration into historic buildings can change significantly the expenses and energy consumption balance in the most energy-unfavourable urban planning segment. A major challenge of renewable energy sources integration is historic buildings value and aesthetics preservation, subject to present legislation compliance and legacy preservation policies. This publication evaluates the solar photovoltaic systems integration in the scope of finding consistency between legal and aesthetic restrictions.
