Julkisen sektorin kiinteistötuotannossa toteutetaan kasvavassa määrin julkisen ja yksityisen sektorin yhteistyötä, jossa yksityinen yritys ottaa vastuun kiinteistöön liittyvistä suunnittelu-, rakentamis- ja ylläpitotoimista pitkäksi ajanjaksoksi. Työn tavoitteena on arvioida elinkaarimallilla toteuttavien kiinteistöhankkeiden toteutusvaihtoehdot, sekä kartoittaa elinkaarihankkeen sisältämiä riskejä hankkeen suunnitteluvaiheessa. Tutkimus suoritetaan kvalitatiivisena tutkimuksena, jota tuetaan tarvittavilla kvantitatiivista tietoa hyödyntävillä laskelmilla. Tutkimusaineistona käytetään aihepiiriin liittyviä akateemisia julkaisuja ja oppikirjoja. Työn toimeksiantajan YIT:n kautta tutkimukseen on saatu arvokasta asiantuntemusta ja materiaalia. Elinkaarihankkeiden hankintamenettelyksi suositellaan kilpailullista neuvottelumenettelyä. Kilpailullinen neuvottelumenettely mahdollistaa tilaajan ja palveluntuottajien välisen dialogin hankintamenettelyn aikana, jolloin osapuolet voivat yhteistyössä valita sopivimman toteutusmallin. Hankkeiden rahoitus voidaan toteuttaa tilaajan rahoituksella tai yksityisrahoituksella. Rahoituksen näkökulmasta tilaajan oma rahoitus on edullisin, mikä ei kuitenkaan vähennä elinkaarimallista saatavia etuja perinteiseen urakointiin verrattuna. Laskelman perusteella tilaajan rahoituksen ja yksityisrahoituksen keskimääräisessä korkotasossa (WACC) on eroa 2,8 %. Projektiyhtiön perustaminen tekee rahoituksesta entistä kalliimpaa, koska taseeseen kohdistuviin kustannuksiin lisätään projektiyhtiön oman pääoman tuottovaatimusta vastaava korko. Palveluntuottajan kannalta olennaiset riskit ovat rakennusvaiheen viivästyminen, kiinteistön käytettävyyden ja soveltuvuuden puutteista aiheutuvat muutostyöt. Palvelumaksun sitominen huonosti ylläpidon todellista kulurakennetta kuvaavaan elinkustannusindeksiin tulee pitkällä sopimuskaudella vähentämään palveluntuottajan toiminnan kannattavuutta. Kiinteistön ylläpidon kustannusindeksi on vuosina 2005–2011 noussut 2,3 % nopeammin vuodessa kuin elinkustannusindeksi.

This paper describes a methodology of using individual engineering undergraduate student projects as a means of effectively and efficiently developing new Design-Build-Test (DBT) learning experiences and challenges.
A key aspect of the rationale for this approach is that it benefits all parties. The student undertaking the individual project gets an authentic experience of producing a functional artefact, which has been the result of a design process that addresses conception, design, implementation and operation. The supervising faculty member benefits from live prototyping of new curriculum content and resources with a student who is at a similar level of knowledge and experience as the intended end users of the DBT outputs. The multiple students who ultimately undertake the DBT experiences / challenges benefit from the enhanced nature of a learning experience which has been “road tested” and optimised.
To demonstrate the methodology the paper will describe a case study example of an individual project completed in 2015. This resulted in a DBT design challenge with a theme of designing a catapult for throwing table tennis balls, the device being made from components laser cut from medium density fibreboard (MDF). Further three different modes of operation will be described which use the same resource materials but operate over different timescales and with different learning outcomes, from an icebreaker exercise focused on developing team dynamics through to full DBT where students get an opportunity to experience the full impact of their design decisions by competing against other students with a catapult they have designed and built themselves.

In the UK, public expenditure on transport infrastructure is nearly £6 billion for the past few years. Over £500 million per year were spent on bridge assessment and strengthening and reducing the backlog of road requiring maintenance. A further £200 million a year will be spent on keeping the safe operation of the network and efficiently through day to day maintenance, lighting and signing . The Department of Transport is planning to extend private sector experience in road management and operation by introducing Design, Build, Finance and Operate (DBFO) This paper investigates the different ways of financing road transport infrastructure including road pricing, private finance in transport infrastructure, the role of the private sector, Design, Build, Finance and Operate (DBFO) schemes, the benefits and problems of such schemes. The paper considers planning gain as a means of financing transport infrastructure with examples of developers to fund link road building and improvements to the local planning system

From the very first steps to execute a building, it is essential to analyze its life cycle. Similarly, we should consider the life cycle when projecting an urban intervention. Professionals of the Facility Management take part in construction projects, developing and managing DBFMO projects (Design, Build, Finance, Maintenance & Operate). Whatever the nature of the promoter is – private or public – promoters are leaders in projects of responsible management of spaces, whether these are work spaces, leisure spaces or residential spaces. They know and identify with the company and its performance, its values and its needs. These professionals give sustainable solutions in the life cycle of buildings (offices and housing), new ways to work and initiatives of innovations linked to current social changes: technology, social networks, and new habits. Concepts where innovation is essential should consider responsible values. Social, economic and sustainable aspects have to associate with the management performed by a Facilities Manager when considering the three groups of stakeholders with which it is linked: economic (shareholders), contractual (users), non-contractual (neighborhoods, organizations, etc.). Marcus Vitruvius Pollio, at the beginning of his book "The Ten Books on Architecture" describes and argues how the distribution in buildings must always adapt to their inhabitants. Let us build cities and buildings with responsible criteria, bearing in mind all its users and the needs of each one of them. Not to mention the need to adapt to future requirements with minimum cost and maximum profitability. These needs, under responsible management, are competencies developed by a Facilities Manager in his day to day. He cares and takes over the entire life cycle of buildings and their surroundings. This work is part of the PhD project whose main aim is to study the added value to the architectural profession when social responsibility criteria are applied in his/her role as Facility Manager.

This paper describes the evolution of a ‘Design - Build-Fly’ (DBF) approach to the delivery and assessment of a Stage Three Aircraft Design module. It focuses on the primary learning outcomes around the design and manufacturing functions associated with the development of a remotely controlled aircraft. The work covers a six year period from 2011 to present mapping the transformation of the module from report based assessment to a more hands on approach resulting in a fully functioning remotely controlled aircraft. Results show that both the staff and student experience improved across key performance metrics including student feedback, learning and competency development. Challenges still remain in methods of placing students within teams and maintaining technical rigour in reporting as students develop vocational skills and more reflective writing styles.

Many engineers currently in professional practice will have gained a degree level qualification which involved studying a curriculum heavy with mathematics and engineering science. While this knowledge is vital to the engineering design process so also is manufacturing knowledge, if the resulting designs are to be both technically and commercially viable.
The methodology advanced by the CDIO Initiative aims to improve engineering education by teaching in the context of Conceiving, Designing, Implementing and Operating products, processes or systems. A key element of this approach is the use of Design-Built-Test (DBT) projects as the core of an integrated curriculum. This approach facilitates the development of professional skills as well as the application of technical knowledge and skills developed in other parts of the degree programme. This approach also changes the role of lecturer to that of facilitator / coach in an active learning environment in which students gain concrete experiences that support their development.
The case study herein describes Mechanical Engineering undergraduate student involvement in the manufacture and assembly of concept and functional prototypes of a folding bicycle.

Project business companies are moving towards solution offering in order to avoid discontinuity of project business and to gain other advantages. An option to implement solution business could be BOOT (Build-Own-Operate-Transfer) business model where a company is given the responsibilities to design, finance, build, own, operate and maintain for example production facilities of a client. The contract is made for 10-30 years, the client pays the solution during this period of time and after contract termination the facilities are transferred to the ownership of the client. The purpose of this study was to provide knowledge about BOOT business model for the company in question and its employees and to create a settlement of the advantages, disadvantages and risks of it. Furthermore, one of the main objectives was to create a description of the network needed to run a BOOT project. The objectives were met through a literature study and an explorative case study with appropriate interviews. Based on this study, the company should be able to evaluate the applicability of BOOT business model to their business environment better.

This Study assessed the development of sludge treatment and reuse policy since the original 1993 National Sludge Strategy Report (Weston-FTA, 1993). A review of the 48 sludge treatment centres, current wastewater treatment systems and current or planned sludge treatment and reuse systems was carried out Sludges from all Regional Sludge Treatment Centres (areas) were characterised through analysis of selected parameters. There have been many changes to the original policy, as a result of boundary reviews, delays in developing sludge management plans, development in technology and changes in tendering policy, most notably a move to design-build-operate (DBO) projects. As a result, there are now 35 designated Hub Centres. Only 5 of the Hub Centres are producing Class A Biosolids. These are Ringsend, Killamey, Carlow, Navan and Osberstown. Ringsend is the only Hub Centre that is fully operational, treating sludge from surrounding regions by Thermal Drying. Killamey is producing Class A Biosolids using Autothermal Thermophilic Aerobic Digestion (ATAD) but is not, as yet, treating imported sludge. The remaining three plants are producing Class A Biosolids using Alkaline Stabilisation. Anaerobic Digestion with post pasteurisation is the most common form of sludge treatment, with 11 Hub Centres proposing to use it. One plant is using ATAD, two intend to use Alkaline Stabilisation, seven have selected Thermal Drying and three have selected Composting. While the remaining plants have not decided which sludge treatment to select, this is because of incomplete Sludge Management Plans and on DBO contracts. Analysis of sludges from the Hub Centres showed that all Irish sewage sludge is safe for agricultural reuse as defined by the Waste Management Regulations {Use of Sewage Sludge in Agriculture) (S.I. 267/2001), providing that a nutrient management plan is taken into consideration and that the soil limits of the 1998 (S.I. 148/1998) Waste Management Regulations are not exceeded.

The business logic in the manufacturing industry has changed in the 21st century. In the current industrial market, manufacturers are driven to provide more comprehensive offerings that go beyond the traditional product-orientation by providing capacity and availability for their customers. From incidental merchandise, services have become the core of manufacturers’ offerings with long-lasting service agreements over the life-cycles of their products. This change is driven both by the need of providers to grow and gain competitive advantage and by increased customer demand caused by customers’ outsourcing trends. The three key drivers for manufacturers’ service strategies are outsourcing trends, saturation of the installed base, and commoditization in product markets. Thus, manufacturers focus on providing industrial solutions which are delivered through relational processes with customers by using solution-driven business models. In the management of marketing activities, this can be regarded as closer customer relationships, service-dominant business logic, and collaboration in solving customers’ problems. However, there are few studies on comprehensive conceptualizations of a solution offering that include different elements and their roles, especially in the context of capital goods industry. Also the transition process needs further studies in a real life context. This study explores the transition process of an industrial company from product to solution business and, as an aid to managing the solution business, explicates the structure and management of an industrial solution offering. There are two themes, the industrial transition process and industrial solution offering. Regarding the industrial transition process, the aim is to understand the supplier view on the process and its execution and to determine the challenges related to the transition process. The industrial solution offering is discussed by its elements and characteristics, as well as management. Furthermore, a special type of build-own-operate-transfer business model is presented and its suitability in the industrial context analyzed. The study includes findings achieved by qualitative methods and from four case companies. Based on the results, it is tentatively suggested that in the industrial solution business, the transition from product to solution business is not a linear project but an evolving process that varies according to customer needs, which suggests that companies need to possess an ability to develop new business models for different customer needs. The industrial solution offering is dynamic as it evolves in collaboration according to the prevailing and latent customer needs, which suggest restructuring of the organization from a product-centric to a customer-centric one. Furthermore, based on the findings, the concept of industrial solutions is defined as an ongoing relational process to satisfy a customer’s particular business or operational requirements, and the concept of industrial solution offering as an entity comprising the customized goods, services, collaboration, and finance needed to fulfill the industrial solution. Finally, the study offers several managerial implications for industrial managers involved in the transition and management of the solution business and its offering.

La colonia experimental de Schorlemerallee y las villas Am Rupenhorn son dos proyectos concluidos en 1930 por los hermanos Wassili y Hans Luckhardt con Alfons Anker en Berlín. Ambos proyectos forman parte del mismo proceso, que comienza en la Colonia -una exploración sobre el lenguaje moderno en una serie de fases sucesivas- y culmina con las Villas. Éstas últimas, realizadas inmediatamente después de la Colonia, son la síntesis de esa experiencia, aunque finalmente acabaron trascendiéndola, ya que se convirtieron en un modelo sobre la casa en la naturaleza, sobre la idea de la villa clásica y sobre los nuevos modos de habitar, alcanzando con el tiempo la condición de canon moderno. A pesar de ello, no es esta condición lo más importante. Lo singular en este caso, es el propio proceso de proyecto –Colonia versus Villas- un verdadero experimento en su concepción, método y resultados, a través del cual sus autores investigan nuevas tecnologías aplicadas a nuevas formas de habitar y desarrollan un nuevo lenguaje, cuyo resultado son unos prototipos tecnológicos, con los que pretenden, como diría Mies van der Rohe: “Me he esforzado por construir una arquitectura para una sociedad tecnológica. He intentado que todo resultara razonable y claro.....para que cualquiera pueda hacer arquitectura.” El momento y lugar no pueden ser más propicios: Berlín entre 1924 y 1930, en el mismo origen del Movimiento Moderno. El experimento se plantea con auténtico rigor científico. Los arquitectos diseñan, construyen y financian su proyecto, controlando todas sus variables. Especialmente, por lo insólito, es el control de la variable económica. Porque este factor, la economía, es para ellos una clave fundamental del proceso. Se trataba de demostrar que la Nueva Arquitectura (o Neues Bauen, como les gustaba denominarla) era capaz de construir mejor y más rápido la vivienda para una nueva sociedad. La revolución y la vanguardia van de la mano: son el Zeitgeist o espíritu de la época, un contexto que es parte sustancial del proceso, y como lo calificarían los Smithson, un contexto heroico. El concepto se centra en la tríada Bauhaus: diseño + tecnología x economía. En cuanto al método, se fijan una serie de parámetros –las variables del experimento- que se agrupan en tres categorías distintas: topología, tipología y tecnología. La combinación de las variables de cada categoría dará lugar a un sistema con unas características determinadas: una definición del espacio, una forma, un lenguaje y una tecnología, características que permiten establecer las reglas para su desarrollo. Los sistemas resultantes son tres, denominados según su doble condición tipológica/ tecnológica: 1. Sistema de muro de carga: Viviendas adosadas en zig-zag o Mauerwerksbauten. 2. Sistema de esqueleto de acero: Viviendas aisladas o Stahlskelettbauten 3. Sistema de hormigón armado: Viviendas en hilera recta o Betonbauten Las villas Am Rupenhorn se plantean a continuación como verificación de este proceso: la síntesis de las categorías desarrolladas en la Colonia. Pero llegan en un momento de gracia, justo cuando los Luckhardt y Anker se encuentran profundamente implicados en el proceso de desarrollo de un nuevo lenguaje y con la reciente experiencia de la Colonia, que ha sido un éxito en casi todos los aspectos posibles. “En 1930, están en la cumbre”, como diría su mejor crítico y antiguo colaborador: Achim Wendschuh. En las Villas, los arquitectos integran su lenguaje, ya plenamente moderno, con sus experiencias previas: las que los relacionan con su reciente expresionismo (que se podría calificar como Kunstwollen) y con la tradición clásica de la cultura arquitectónica alemana: el sentido del material que deben a Semper y la sensibilidad hacia el paisaje, que toman de Schinkel. El extraordinario interés de las Villas se debe a factores como el tratamiento de la relación dual, poco habitual en la arquitectura moderna, la síntesis de lenguajes y las circunstancias de su momento histórico, factores que las han convertido en una propuesta única e irrepetible de una de las vías experimentales más interesantes y desconocidas de la Modernidad. ABSTRACT The experimental Housing Estate of Schorlemerallee and the Am Rupenhorn Villas are two projects completed by the brothers Wassili and Hans Luckhardt with Alfons Anker in Berlin in 1930. Both projects are part of the same process, starting with the Housing Estate --an exploration of the modern language in a series of phases- which culminates with the Villas project. The Villas Am Ruperhorn, designed immediately after the Housing development, are the synthesis and crowning point of this experience, even finally over passing it, since they have become a model of the house in nature, related with both the ideal of the classical villa and the new ways of life, reaching the condition of a modern canon. However, this is not its most important issue. The most remarkable condition is the project process itself -Housing versus Villas- a true experiment in concept, method and results, in which the authors research new technologies for new ways of living, developing an innovative language, with results in new prototypes, in the way Mies van der Rohe was looking for: “I have tried to make an architecture for a technological society. I have wanted to keep everything reasonable and clear… to have an architecture that anybody can do." The time and place could not be more favourable: Berlin from 1924 to 1930, in the very origin of Modern Movement. The experiment takes place with genuine scientific accuracy. Architects design, build and finance their own project, controlling all variables. Especially, and quite unusual, the control of the economic variable. Precisely the economic factor is for them a fundamental key to the process. It was shown to prove that the new architecture (or Neues Bauen, as they liked to call it) was able to build not only faster, better and more efficient dwellings for a new society, but also at lower cost. Revolution and Avant-garde use to move forward together, because they share the Zeitgeist --or time's spirit--, a context which is a substantial part of the process, and as the Alison & Peter Smithsons would describe, an heroic context. The concept focuses on the Bauhaus triad: Design + Technology x Economy. For the method, a number of variables are fixed --the experimental parameters-- that are later grouped into three distinct categories: Topology, Typology and Technology. The combination of these variables within each category gives way to several systems, with specific characteristics: a definition of space, a form, a language and a technology, thus allowing to establish the rules for its development: The resulting systems are three, called by double typological / technological issue: 1. Terraced Housing in zig-zag or Mauerwerksbauten (bearing wall system) 2. Detached Housing or Stahlskelettbauten (steel skeleton system) 3. Terraced Housing in one row or Betonbauten (reinforced concrete system) The Am Rupenhorn Villas are planned as the check of this process: the synthesis of the categories developed all through the Housing Estate research. The Am Ruperhorn project is developed in a crucial moment, just as the Luckhardts and Anker are deeply involved in the definition process of a new language after the recent experience of Schorlemerallee, which has been a success in almost all possible aspects. "In 1930, they are on the top” has said his best critic and long-time collaborator, Achim Wendschuh. In the Villas, the authors make up their fully modern language with their own background, related with their recent Expressionist trend (Kunstwollen) and with the classical tradition of the German architectural culture: the notion of material related with Semper and the sensible approach to the landscape, linked with Schinkel. Its extraordinary interest lay on diverse factors, such as dual relationships, unusual in modern architecture, synthesis of languages and circumstances of their historical moment, all factors that have become a unique and unrepeatable proposal in one of the most extraordinary experimental ways of Modernity.

This study explores the ongoing pedagogical development of a number of undergraduate design and engineering programmes in the United Kingdom. Observations and data have been collected over several cohorts to bring a valuable perspective to the approaches piloted across two similar university departments while trialling a number of innovative learning strategies. In addition to the concurrent institutional studies the work explores curriculum design that applies the principles of Co-Design, multidisciplinary and trans disciplinary learning, with both engineering and product design students working alongside each other through a practical problem solving learning approach known as the CDIO learning initiative (Conceive, Design Implement and Operate) [1]. The study builds on previous work presented at the 2010 EPDE conference: The Effect of Personality on the Design Team: Lessons from Industry for Design Education [2]. The subsequent work presented in this paper applies the findings to mixed design and engineering team based learning, building on the insight gained through a number of industrial process case studies carried out in current design practice. Developments in delivery also aligning the CDIO principles of learning through doing into a practice based, collaborative learning experience and include elements of the TRIZ creative problem solving technique [3]. The paper will outline case studies involving a number of mixed engineering and design student projects that highlight the CDIO principles, combined with an external industrial design brief. It will compare and contrast the learning experience with that of a KTP derived student project, to examine an industry based model for student projects. In addition key areas of best practice will be presented, and student work from each mode will be discussed at the conference.

Default invariance is the idea that default does not change at any scale of law and finance. Default is a conserved quantity in a universe where fundamental principles of law and finance operate. It exists at the micro-level as part of the fundamental structure of every financial transaction, and at the macro- level, as a fixed critical point within the relatively stable phases of the law and finance cycle. A key point is that default is equivalent to maximizing uncertainty at the micro-level and at the macro-level, is equivalent to the phase transition where unbearable fluctuations occur in all forms of risk transformation, including maturity, liquidity and credit. As such, default invariance is the glue that links the micro and macro structures of law and finance. In this essay, we apply naïve category theory (NCT), a type of mapping logic, to these types of phenomena. The purpose of using NCT is to introduce a rigorous (but simple) mathematical methodology to law and finance discourse and to show that these types of structural considerations are of prime practical importance and significance to law and finance practitioners. These mappings imply a number of novel areas of investigation. From the micro- structure, three macro-approximations are implied. These approximations form the core analytical framework which we will use to examine the phenomena and hypothesize rules governing law and finance. Our observations from these approximations are grouped into five findings. While the entirety of the five findings can be encapsulated by the three approximations, since the intended audience of this paper is the non-specialist in law, finance and category theory, for ease of access we will illustrate the use of the mappings with relatively common concepts drawn from law and finance, focusing especially on financial contracts, derivatives, Shadow Banking, credit rating agencies and credit crises.
