Virtual Design and Construction (VDC) introducerades tidigt på 2000-talet för att främja ett arbete med datorbaserade modeller samt involvering av produktionsplanering i designfasen. VDC är ett koncept som idag har anammats inom många bygg- och konsultföretag för att utveckla arbetet med Building Information Model (BIM), innovationer och samverkan inom byggprojekt. Konceptet VDC förändras ständigt och omdefinieras av enskilda individer och företag. Det här resulterar i att det råder en begreppsförvirring hur VDC ska definieras och hur arbete med VDC ska genomföras. Vidare tenderar många byggprojekt att vara fragmenterade med projektmedlemmar som främst fokuserar på sitt eget teknikområde. För att minska fragmentering mellan projektmedlemmar kan integrerade arbetsmetoder tillämpas. Syftet med examensarbetet är därför dels att undersöka innebörden av VDC som koncept och även hur VDC kan stimulera integrerade arbetsmetoder. Ämnet utforskas kvalitativt med vetenskaplig litteratur och intervjustudie. Den vetenskapliga litteraturen definierar konceptuellt VDC och två integrerade arbetsmetoder Integrated Concurrent Engineering (ICE) och Integrated Project Delivery (IPD). Varvid intervjustudien inkluderar respondenter från byggsektorn vars reflektioner om det studerade ämnet presenteras. Studien är geografiskt avgränsad till Sverige.  I resultatet påvisas den rådande tvetydigheten huruvida VDC definieras. För att undvika begreppsförvirring kan det vara behövligt med en gemensam definition av VDC i byggbranschen och även nationella riktlinjer vilka beskriver hur arbete med VDC ska utföras. Vidare kan VDC stimulera ett integrerat arbetssätt genom en ökad samhörighet inom byggprojekt med bland annat gemensamma formuleringar av projektmål och gemensam problemlösning mellan projektmedlemmar. / Virtual Design and Construction (VDC) was introduced early in the 21st century in order to encourage work with computer based models and construction planning in the design phase. VDC is a concept that has been embraced by several construction and consulting companies in order to develop their work with Building Information Model (BIM), innovations and cooperation within construction projects. VDC is a concept that keeps evolving and is being redefined by individuals and companies. This has contributed to a conceptual confusion within the construction sector about the definition of VDC. Furthermore, construction projects tend to be fragmented with project members that are working in silos and primarily focusing on their own discipline. In order to decrease the fragmentation within construction projects integrated working methods can be applied. Therefor the purpose of this master thesis is to explore the concept VDC and how it can stimulate integrated working methods.  The study is examined using qualitative methods based on scientific literature and an interview study. The scientific literature is defining VDC conceptually and two integrated working methods Integrated Concurrent Engineering (ICE) and Integrated Project Delivery (IPD). Furthermore, the interview study includes respondents from the construction industry whose reflections and thoughts about the subject are being presented. The study is geographically limited to Sweden.  The result shows the current ambiguity of how VDC is defined. In order to avoid a conceptual confusion a common definition should be formulated with national guidelines that describe how work with VDC should be conducted. Furthermore, VDC can stimulate an integrated approach through increased cohesion within construction projects, including common objectives within the project and joint problem solving between project members.

Project process\' hindrances over office architectural design production are common at civil construction sector, implying on schedule loss, reworks and higher costs. Many academic literature approaches to that hindrance resulted from failure in project process. Predominantly failures concern translating customer needs and expectations into design conditions. This research objectives to propose scope of work guidelines, securing customer satisfaction and avoiding unforeseen additional costs, reworks, schedule and project benefit loss. Additionally, for each guideline proposed, it is suggested an accountable for it (project manager, architect or client). The adopted methodology was the research and analysis of project methodologies from academic literatures, contenting responsibilities definitions and design criteria that should be considered on the approved scope of work. Furthermore, the creation and implementation of an interview plan with one Brazilian high concept corporative architecture firm and its three clients, in a way that it is possible to measure client\'s point of view over contracted project process. Results from the interviews identified scope definition and project process planning hindrances. Then, in comparison with academic literatures, main project and scope of work issues were identified and used as base to the scope of work development guidelines. / A produção de projetos de arquitetura e engenharia no setor de construção civil apresenta entraves em seus processos de projeto, que implicam em perda de prazo, aumento de custos de projeto e retrabalhos. Diversos autores abordam falhas na gestão do processo de projeto, principalmente na interpretação das necessidades dos clientes e na definição dos critérios que o projeto deve seguir, alguns não previstos no escopo de contratação entre a empresa de arquitetura e o cliente. Esta pesquisa propõe diretrizes para que as empresas de arquitetura possam, junto ao gerente de projetos dos clientes, definir um escopo de serviços em que retrabalho, custos adicionais, atrasos e a insatisfação do cliente com o processo sejam reduzidos ou evitados. Para cada diretriz, há também a definição de quem é o responsável por executá-la (se o arquiteto ou o cliente). A metodologia utilizada para obtenção desse objetivo foi o levantamento e revisão de bibliografia sobre metodologias de projeto e de contratos de projetos, que auxiliem na definição de responsabilidades, atividades e critérios de projeto. Em acréscimo, foi formulado um roteiro de entrevista e eleita uma empresa de arquitetura corporativa com experiência de mercado no Brasil, assim como três clientes da mesma, de forma a mapear o ponto de vista do cliente sobre o processo empregado pela contratada. Com os resultados das entrevistas, fez-se uma análise comparativa entre os métodos de projeto empregados pela empresa de arquitetura e o encontrado em bibliografia, identificando os principais entraves no desenvolvimento e definição do escopo de serviços. Por fim, tais resultados foram utilizados como base para propor diretrizes para que o escopo de serviços entre arquitetos e clientes prevejam revisões de projeto, traduzam efetivamente as necessidades do cliente e atendam prazos e custos esperados.

The goal of this Ph.D. research is to explore the IPD contractual strategies, to highlight the elements that distinguish IPD from a traditional delivery approach, to analyze how trust-based relationships are established and promoted, and to demonstrate if/how trust and IPD contractual principles correlate. The result of this research will promote the understanding of the industry on the strategies that promote trust and integration through real world case studies. The significance of the subject becomes more evident when reflecting on the current industry's crisis: productivity loss, fragmented delivery process, and lack of trust and collaboration. Through a literature review a Project Delivery and Contracting Strategies (PDCS) framework, an IPD traits framework, and a trust-Building framework are developed. The frameworks are used as the organizational tools to structure and inquire relevant information on the two IPD projects. An expert panel is assembled to discuss the frameworks and the findings of literature analysis and to seek the industry's insight on the units of analysis for contract, and the units of measure for trust. The units of analysis for contract are elements, such as strategies for risks/rewards sharing, liability considerations, decision making authority, and governance. The units of measure for trust are the individuals' perception, and the trust-building attributes as outlined in table 4-1. Two IPD projects were selected and their contract agreements were studied. A questionnaire including both open-ended questions and multiple choice questions was developed based on the information collected through: 1. the IPD agreements in each case study, 2. the literature-based frameworks on trust and project delivery contracting strategies. Accordingly, two IPD case studies are developed following the analysis of their IPD agreements and the individual one-on-one interviews with their key IPD players. The trust-building framework presented in this work includes a series of techniques that the contracting parties can follow when establishing their contractual and managerial strategies and also when interacting with each other. / Ph.

Integrated Project Delivery (IPD) combined with Target Value Design (TVD) is a better way to deliver value for the client than traditional guaranteed maximum price (GMP) methods. With traditional GMP delivery methods, the interests of the parties are often at odds. The goal of IPD is to align all party interests in order to achieve a win-win scenario. Due to the aligning nature of IPD and the fact that each party’s success is dependent on achieving the project objectives as a whole; a non-biased, transparent, decision-making process is necessary in order to deliver the project objectives within the constraints of the TVD. Thus delivering the expected value for the client and ensuring that all parties achieve project success. The need for this transparent decision-making process is compounded by the fact that a “target” based system rapidly declines to a less than optimal state if there is no unbiased decision-making process in place. If we treat the entire lifespan of a project as the complex system that it is, we can begin to take advantage of the hierarchical nature of complex systems. The goal of this paper is to show that by modeling the life span of a project through a multi-criteria decision making model, built on a hierarchical framework will allow you to find a non-inferior solution to your TVD. I’m proposing to use Hierarchical Holographic Modeling (HHM) as the framework for an Analytical Hierarchical Process (AHP) multi-criteria decision-making model complete with post-optimality analysis as the preferred project management method.

Partnering som arbetssätt har funnits i Sverige sedan slutet av 90-talet och kommit att bli allt vanligare, särskilt inom offentligt byggande. Arbetssättet är en reaktion på det traditionella förfarandet som kritiserats för att vara fragmentiserat och innebära dåligt utnyttjande av kunskap och skapa många konflikter. I en integrerad organisation och med en iterativ process utvecklar och genomför alla aktörer projektet med full transparens i alla delprocesser i syfte att maximera värdet av slutprodukten och sätta kundens behov i centrum. ByggDialog är ett företag som från start specialiserat sig på partnering och som organiserar och leder produktbestämningsskedet ofta kallat Fas 1, varefter man också samordnar alla entreprenörer och utför byggentreprenaden med egen arbetskraft. ByggDialog vill utveckla sitt arbete i Fas 1 och skapa en så flödeseffektiv process som möjligt för att komma till produktion inom rimlig tid. Detta är viktigt då man strävar efter effektivitet i allmänhet men också för att det ska vara möjligt att med god säkerhet och små avvikelser prognostisera resursbehov, tillväxttakt och resultat. Flödeseffektivitet är ett begrepp hämtat från Lean-teorin som har sitt ursprung i Toyotas bilfabriker. Det handlar om att skapa en process där icke värdeskapande aktiviteter elimineras och fokus ligger på densiteten i värdeöverföringen till produkten och dess flöde. Syftet med denna rapport är att applicera dessa teorier på ByggDialogs processer i Fas 1 och att genom intervjuer med personer med stor erfarenhet kartlägga icke värdeskapande aktiviteter i Fas 1. I studien ingick också att föreslå åtgärder till förbättrad flödeseffektivitet. Det gjordes även en ansats till att beräkna flödeseffektiviteten i ett antal genomförda projekt i syfte att utreda möjligheten till lämplig indikator för företagets förbättringsarbete av Fas 1. Det visade sig att flödeseffektiviteten i Fas 1 sammanfattningsvis kan påverkas positivt genom bland annat öppenhet, integrerade organisationer, standardiserade arbetssätt, iterativa projekteringsmetoder och tydlig projektledning. En indikator för flödeseffektivitet som beaktar kvoten mellan värdeskapande tid och genomloppstid genom BTA visade sig vara komplex att ta fram. En framkomlig väg är dock att endast låta indikatorn avspegla genomloppstid genom BTA eller produktionskostnad. Fördjupade studier rekommenderas ByggDialog för att söka den mest användbara metoden för uppföljning och mätning av effektiviteten i Fas 1. / Partnering as a working method has existed in Sweden since the late 90s and has become increasingly common, especially in public construction. The way of working is a reaction to the traditional procedure that has been criticized for being fragmented and misleading knowledge and creating many conflicts. In an integrated organization and with an iterative process, all players develop and implement the project with full transparency in all sub-processes to maximize the value of the product and put the customer's needs in focus. ByggDialog is a company that from the start specializes in partnering and who organizes and leads the design phase often called Phase 1, after which one also coordinates all contractors and performs the construction with their own workforce. ByggDialog wants to develop their work in Phase 1 and create a process as flow-efficient as possible to reach production within a reasonable time. This is important as one strives for efficiency in general, but also for it to be possible to forecast resource needs, growth rates and results with good precision and small deviations. Flow efficiency is a concept derived from Lean theory that originates from Toyota's car factories. It is about creating a process where non-value-creating activities are eliminated, and the focus is on the density of the value transfer to the product and its flow. The purpose of this report is to apply these theories to ByggDialog's processes in Phase 1 and to survey non-value-creating activities in Phase 1 through interviews with people with great experience of Phase 1. The study also included proposing measures for improved flow efficiency. An effort was also made to calculate the flow efficiency in several completed projects to investigate the possibility of an appropriate indicator for the company's improvement work on Phase 1. In summary, it turned out that flow efficiency in Phase 1 can be positively affected by openness, integrated organizations, standardized working methods, iterative design methods and distinct project management. An indicator of flow efficiency that considers the ratio of value-creating time and throughput divided by BTA proved to be too complex to develop. A viable route, however, is to only let the indicator reflect the throughput divided by BTA or production cost. In-depth studies are recommended for ByggDialog to seek the most useful method for monitoring and measuring the effectiveness of Phase 1.
