Projektering vid renoveringsprojekt ser ofta väldigt olika ut och skiljer sig från projekteringen vid nyproduktion. Det är därför svårt att ta fram en mall eller standard för hur produktionen ska genomföras och avvikelser kan lätt uppstå.  Avvikelser som uppstår inom renoveringsprojekt kan visa sig vara väldigt tidskrävande eller i värsta fall leda till stopp inom produktionen och det ställs stora krav på projektörerna som måste ha goda kunskaper inom området.  Inom ramen för examensarbetet ingår att identifiera och analysera hur kritiska avvikelser inom renoveringsprojekt uppstår samt hur man ska göra för att hantera detta under ett tidigt skede av renoveringen. Som referensobjekt under examensarbetet används renoveringen av bostadsrättföreningen Kurortsparken i Nynäshamn. Rapporten kommer att analysera de avvikelser som uppstått under produktionen samt ge förslag för hur man kunde ha hanterat projektet och de avvikelser som uppstod annorlunda. / The planning for renovation projects often look very different and distinct from the planning for new production. It is therefore difficult to set up a template or standard for how the production will be implemented and variations may readily occur. Deviations that arise in renovation projects can prove to be very time consuming and worst lead to a stop in production and the concern results in the designer that must be experienced.  As part of the thesis is to find and analyze the critical differences in the renovation project and how to do to manage it during the early stages of renovation. As a reference point for the thesis is the renovation of the housing association Kurortsparken in Nynäshamn. The report will analyze the deviations that occurred during the production and to give suggestions for how to handle the project and the changes that occurred differently.

This study is based on the development of a new software, which is used as a recommendationtool for selecting the best product. As part of the software development has an external partnerbeen asked to assist. The report will process the expectations that different people have on anew project but also how information is communicated to an external partner.The results from this study show that a software's function is closely linked to its usability.Therefore shall usability been taken into account when a new resource is created. The study alsoshows the importance of being able to share information, on how the program will beconstituted, to someone outside the organization. / Denna studie hade sin utgångspunkt i ett utvecklingsprojekt av en mjukvara vilken skallanvändas som ett rekomendationsverktyg för att välja ut rätt produkt. Som ett led i dennautveckling har en extern part kopplats in för att hjälpa till med utvecklingen.

This study uses information gleaned from a sample of 102 public sector project managers to assess the interrelationships among project manager roles, responsibilities, and competencies in the planning and implementation stages of the project life cycle. The results of confirmatory factor analysis and structural equation modeling revealed that project managers use different subsets of their skills to influence outcomes at these two stages of the project. For example, while the project manager's organizational and technical skills tend to have some influence during the project planning stage, managerial, leadership and people skills appear to have more influence during the project implementation stage. Implications of these and our other findings for the practice of project management in public sector organizations are discussed.

Purpose: The purpose of this paper is to assess the management of public-sector projects in Portugal paying particular attention to the extent to which total quality management (TQM) principles are being utilized in such projects. Design/methodology/approach: Based on an extensive review of the literature, nine propositions are advanced about the interrelationships among seven factors that were identified, in a previous study, as having some influence on the management process in the planning and implementation of public-sector projects in Portugal. Structural equation modeling was used to investigate these propositions using data obtained from 211 respondents to a survey of project managers from municipalities across Portugal. Findings: The results of the structural equation model indicate that the TQM components working in tandem with project-management-specific variables provide a systematic means of managing the planning and implementation stages of projects, with technical items being critical in the planning stage and softer management items becoming important in the implementation stage. Research limitations/implications: Readers should be careful not to generalize the findings in a global context or for private sector projects. However, researchers are encouraged to extend this study by including other planning and implementation variables with a view to discerning what particular characteristics of a project make it more amenable to TQM solutions. Practical implications: The findings are presented to show how the key components of TQM, customer focus, employee involvement and continuous involvement, can be applied during the planning and implementation stages of projects. Originality/value: The sample size of 211 is representative of the underlying population of project managers in municipalities across Portugal and is comparatively large in relation to other empirical project management studies from Portugal, lending credence to the generalizability of these finding to public-sector projects in Portugal.

Uncertainty and complexity are two factors that make project planning a challenging task. Companies operating in a multiple project Engineer-to-Order environment face an additional dimension of difficulties because of interactions between projects. The changing environment and frequency of unforeseen events increases the difficulty of planning and re-planning and requires flexibility. This study explores how project planning is conducted and what the associated challenges are in a multiple project ETO context. To that end, a case study of a company operating in such a context was investigated using a qualitative approach. In so doing, we shed light on the challenges and provide some insight to mitigate the challenges. The findings suggest that there are challenges related to resource allocation, prioritization, communication and progress updates, and keeping the plan up to date and valid. Practically, the main takeaways are that synergies may be found when leveraging workflow reliability and flexibility as it comes down to deciding when the respective approach is suitable to mitigate the challenges found in the study. In addition, we suggest that prioritization should be integrated into the planning processes to create a better consensus within and among projects. Lastly, we also suggest an additional precondition for releasing work to production.

yes / This paper is a literature review of Logical Framework ideas for the management of the cycle for the planning and implementation of development projects - the "Project Cycle" (MacArthur 1994) The ideas and nature of the LogFrame (as it is generally called) are deceptively simple, with all the thinking and targets for a project represented in a simple 16 cell worksheet, which it is intended should be written on one or at the most two sheets of A4 paper. The underlying intention of this approach is for the objectives of a project or any other intervention to be explicitly defined from an early stage, so as to strengthen the logic of the planning at different levels of a project's performance, and the evaluation of progress when the plans are implemented. A summary matrix for the presentation of all this was first proposed in the US Government in 1970, and the idea not only soon took firm root there in AID, but has been adopted in original or modified form by a very large proportion of Development Assistance Agencies. The appeal of the simple logic behind the LogFrame idea has been very strong, and the ideas are an established part of all the set of tools of all development planners working at the micro level. / ID-7098D - Project Planning and Financial Analysis

Die Verwendung von Simulationen zur Unterstützung traditioneller Planungsverfahren für Bauprojekte hat viele Vorteile, die in verschiedenen akademischen Forschungen vorgestellt wurden. Viele Anwendungen haben erfolgreich das Potenzial der Simulationsmethode zur Verbesserung der Qualität der Projektplanung demonstriert. Doch eine breite Anwendung der Simulationsmethoden zur Unterstützung der Planung von Bauprojekten konnte sich in der Praxis bis zum jetzigen Zeitpunkt nicht durchsetzen. Aufgrund einiger großer Hindernisse und Herausforderungen ist der Einsatz im Vergleich zu anderen Branchen noch sehr begrenzt. Die Komplexität sowie die dynamischen Wechselprozesse der unterschiedlichen Bauvorhaben stellen die erste Herausforderung dar.Die Anforderungen machen es sehr schwierig die verschieden Situationen realistisch zu modellieren und das Verhalten von Bauprozessen und die Interaktion mit den zugehörigen Ressourcen für reale Bauvorhaben darzustellen. Das ist einer der Gründe für den Mangel an speziellen Simulationswerkzeugen in der Bauprojektplanung. Die zweite Herausforderung besteht in der großen Menge an Projektinformationen, die in das Simulationsmodell integriert und während des gesamten Lebenszyklus des Projekts angepasst werden müssen. Die Erstellung von Simulationsmodellen, Simulationsszenarien sowie die Analyse und Verifizierung der Simulationsergebnisse ist langwierig. Ad-hoc Simulation sind daher nicht möglich. Zur Erstellung zuverlässiger Simulationsmodelle sind daher umfangreiche Ressourcen und Mitarbeiter mit speziellen Fachwissen erforderlich. Die vorgestellten Herausforderungen verhindern die breite Anwendung der Simulationsmethode zur Unterstützung der Bauprojektplanung und das Einsetzen der Software als wesentlicher Bestandteil des Arbeitsablaufes für die Bauplanung in der Praxis. Die Forschungsarbeit in dieser Arbeit befasst sich mit diesen Herausforderungen durch die Entwicklung eines Ansatzes sowie einer Plattform für die schnelle Aufstellung von Simulationsmodellen für Bauprojekte. Das Hauptziel dieser Forschung ist die Entwicklung eines integrierten und referenzmodellbasierten BIM Simulationsansatz zur Unterstützung der Planung von Bauprojekten und die Möglichkeit der Zusammenarbeit aller am Planungs- und Simulationsprozess beteiligten Akteure. Die erste Herausforderung wird durch die Einführung eines RPM-Konzepts (Reference Process Model) durch die Modellierung von Konstruktionsprozessen unter Verwendung von Business Process Modeling and Notation (BPMN) angegangen. Der Vorteil der RPM Modelle ist das sie bearbeitet und modifiziert können und dass sie automatisch als einsatzbereite Module in Simulationsmodelle umgewandelt werden können. Die RPM-Modelle enthalten auch Informationen zu Ressourcenanforderungen und andere verwandte Informationen für verschiedene Baubereiche mit unterschiedlichen Detaillierungsgraden. Die Verwendung von BPMN hat den Vorteil, dass die Simulationsmodellierung für das Projektteam, einschließlich derjenigen, die sich nicht mit der Simulation auskennen, flexibler, interoperabler und verständlicher ist. Bei diesem Ansatz ist die Modellierung von Referenzprozessmodellen vollständig von den Simulationskernkomponenten getrennt, um das Simulations-Toolkit generisch und erweiterbar für verschiedenste Konstruktionsbereiche wie Gebäude und Brücken. Der vorgestellte Forschungsansatz unterstützt die kontinuierliche Anwendung von Simulationsmodellen während des gesamten Projektlebenszyklus. Die Simulationsmodelle, die zur Unterstützung der Planung in der frühen Entwurfsphase erstellt werden, können von Simulationsexperten während der gesamten Planungs- und Bauphase weiter ausgebaut und aktualisiert werden. Die zweite Herausforderung wird durch die direkte Integration der Building Information Modeling (BIM) -Methode in die Simulationsmodellierung auf der Grundlage des Industry Foundation Classes-IFC (ISO 16739) , dem am häufigsten verwendeten BIM-Austauschformat, angegangen. Da die BIM-Modelle einen wichtigen Teil der Eingabeinformationen von Simulationsmodellen enthalten, können sie als Grundlage für die Visualisierung von Ergebnissen in Form von 4D-BIM-Modellen verwendet werden. Diese Integration ermöglicht die schnelle und automatische Filterung und Extraktion sowie die Umwandlung notwendiger Informationen aus BIM Entwurf-Modellen. Um die Erstellung detaillierter Projektmodelle zu beschleunigen, wurde eine spezielle Methode für die halbautomatische Top-Down-Detaillierung von Projektstammmodelle entwickelt, die notwendige Eingangsdaten für die Simulationsmodelle sind. Diese Methode bietet den Vorteil, dass Konstruktionsalternativen mit minimalen Änderungen am Simulationsmodell untersucht werden können. Der entwickelte Ansatz wurde als Software- Prototyp in Form eines modularen Construction Simulation Toolkit (CST) basierend auf der Discrete Event Simulation (DES)- Methode und eines Collaboration- Webportals (ProSIM) zum Verwalten von Simulationsmodellen implementiert. Die so eingebettete Simulation ermöglicht mit minimalen Änderungen die Bewertung von Entwurfsalternativen und Konstruktionsmethoden auf den Bauablauf. Produktions- und Logistiksvorgänge können gleichzeitig in einer einheitlichen Umgebung simuliert werden und berücksichtigen die gemeinsam genutzten Ressourcen und die Interaktion zwischen Produktions- und Logistikaktivitäten. Es berücksichtigt auch die Änderungen im Baustellenlayout während der Konstruktionsphase. Die Verifizierung und Validierung des vorgeschlagenen Ansatzes wird durch verschiedene hypothetische und reale Bauprojekten durchgeführt.:1 Introduction: motivation, problem statement and objectives 1.1 Motivation 1.2 Problem statement 1.3 Objectives 1.4 Thesis Structure 2 Definitions, Related work and background information 2.1 Simulation definition 2.2 Simulation system definition 2.3 Discrete Event Simulation 2.5 How simulation works 2.6 Workflow of simulation study 2.7 Related work 2.8 Traditional construction planning methods 2.8.1 Gantt chart 2.8.2 Critical Path Method (CPM) 2.8.3 Linear scheduling method/Location-based scheduling 2.9 Business Process Model and Notation 2.10Workflow patterns 2.10.1 Supported Control Flow Patterns 3 Reference Process-based Simulation Approach 3.1 Reference Process-based simulation approach 3.2 Reference Process Models 3.3 Reference process model for single task 3.4 Reference process models for complex activities 3.5 Process Pool 3.6 Top-down automatic detailing of project schedules 3.7 Simulation model formalism 3.8 Fundamental design concepts and application scope 4 Data Integration between simulation and construction Project models 4.1 Data integration between BIM models and simulation models 4.1.1 Transformation of IFC models to Graph models 4.1.2 Checking BIM model quality 4.1.3 Filtering of BIM models 4.1.4 Semantic enrichment of BIM models 4.1.5 Reference process models and BIM models 4.2 Reference Process Models and resources models 4.3 Process models and productivity factors 5 Construction Simulation Toolkit 5.1 System architecture and implementation 5.2 Basic steps to create a CST simulation model 5.3 CST Simulation components 5.3.1 Input components 5.3.2 Process components 5.3.3 Output components 5.3.4 Logistic components 5.3.5 Collaboration platform ProSIM 6 Case Studies and Validation 6.1 Verification and Validation of Simulation Models 6.2 Verification and validation techniques for simulation models 6.3 Case study 1: generic planning model 6.4 Case study 2: high rise building 6.4.1 Scenario I: effect of changing number of workers on structural work duration 6.4.2 Scenario II: simulation of structural work on operation level 6.4.3 Scenario III: automatic generation of detailed project schedule 6.5 Case study 3: airport terminal building 6.5.1 Multimodel Container 6.5.2 Scenario I: automatic generation of detailed project schedule 6.5.3 Scenario II: Find the minimal project duration 6.5.4 Scenario III: construction work for a single floor 7 Conclusions and Future Research 7.1 Conclusions 7.2 Outlook of the possible future research topics 7.2.1 Integration with real data collecting 7.2.2 Multi-criteria optimisation 7.2.3 Extend the control-flow and resource patterns 7.2.4 Consideration of further structure domains 7.2.5 Considering of space allocation and space conflicts 8 Appendix - Scripts 9 Appendix B - Reference Process Models 9.1 Reference Process Models for structural work 9.1.1 Wall 9.1.2 Roof 9.1.3 Foundations 9.1.4 Concrete work 9.1.5 Top-Down RPMs for structural work in a work section 10 Appendix E 10.1 Basic elements of simulation models in Plant Simulation 10.2 Material Flow Objects 11 References / Using simulation to support construction project planning has many advantages, which have been presented in various academic researches. Many applications have successfully demonstrated the potential of using simulation to improve the quality of construction project planning. However, the wide adoption of simulation has not been achieved in practice yet. It still has very limited use compared with other industries due to some major obstacles and challenges. The first challenge is the complexity of construction processes and projects planning methods, which make it very difficult to develop realistic simulation models of construction processes and represent their dynamic behavior and the interaction with project resources. This led to lack of special simulation tools for construction project planning. The second challenge is the huge amount of project information that has to be integrated into the simulation model and to be maintained throughout the design, planning and construction phases. The preparation of ad-hoc simulation models and setting up different scenarios and verification of simulation results usually takes a long time. Therefore, creating reliable simulation models requires extensive resources with advanced skills. The presented challenges prevent the wide application of simulation techniques to support and improve construction project planning and adopt it as an essential part of the construction planning workflow in practice. The research work in this thesis addresses these challenges by developing an approach and platform for rapid development of simulation models for construction projects. The main objective of this research is to develop a BIM integrated and reference process-based simulation approach to support planning of construction projects and to enable collaboration among all actors involved in the planning and simulation process. The first challenge has been addressed through the development of a construction simulation toolkit and the Reference Process Model (RPM) method for modelling construction processes for production and logistics using Business Process Modelling and Notation (BPMN). The RPM models are easy to understood also by non-experts and they can be transformed automatically into simulation models as ready-to-use modules. They describe the workflow and logic of construction processes and include information about duration, resource requirements and other related information for different construction domains with different levels of details. The use of BPMN has many advantages. It enables the understanding of how simulation models work by project teams, including those who are not experts in simulation. In this approach, the modelling of Reference Process Models is totally separated from the simulation core components. In this way, the simulation toolkit is generic and extendable for various construction types such as buildings, bridges and different construction domains such as structural work and indoor operations. The presented approach supports continuous adoption of simulation models throughout the whole project life cycle. The simulation model which supports project planning in the early design phase can be continuously extended with more detailed RPMs and updated information through the planning and construction phases. The second challenge has been addressed by supporting direct integration of Building Information Modelling (BIM) method with the simulation modelling based on the Industry Foundation Classes IFC (ISO 16739) standard, which is the most common and only ISO standard used for exchanging BIM models. As the BIM models contain the biggest part of the input information of simulation models and they can be used for effective visualization of results in the form of animated 4D BIM models. The integration between BIM and simulation enables fast and semi-automatic filtering, extraction and transformation of the necessary information from BIM models for both design and construction site models. In addition, a special top-down semi-automatic detailing method was developed in order to accelerate the process of preparing detailed project schedules, which are essential input data for the simulation models and hence reduce the time and efforts needed to create simulation models. The developed approach has been implemented as a software prototype in the form of a modular Construction Simulation Toolkit (CST) based on the Discrete Event Simulation (DES) method and an online collaboration web portal 'ProSIM' for managing simulation models. The collaboration portal helps to overcome the problem of huge information and make simulation models accessible for non simulation experts. Simulation models created by CST toolkit facilitate the evaluation of design alternatives and construction methods with minimal changes in the simulation model. Both production and logistic operations can be simulated at the same time in a unified environment and take into account the shared resources and the interaction between production and logistic activities. It also takes into account the dynamic nature of construction projects and hence the changes in the construction site layout during the construction phase. The verification and validation of the proposed approach is carried out through various academic and real construction project case studies.:1 Introduction: motivation, problem statement and objectives 1.1 Motivation 1.2 Problem statement 1.3 Objectives 1.4 Thesis Structure 2 Definitions, Related work and background information 2.1 Simulation definition 2.2 Simulation system definition 2.3 Discrete Event Simulation 2.5 How simulation works 2.6 Workflow of simulation study 2.7 Related work 2.8 Traditional construction planning methods 2.8.1 Gantt chart 2.8.2 Critical Path Method (CPM) 2.8.3 Linear scheduling method/Location-based scheduling 2.9 Business Process Model and Notation 2.10Workflow patterns 2.10.1 Supported Control Flow Patterns 3 Reference Process-based Simulation Approach 3.1 Reference Process-based simulation approach 3.2 Reference Process Models 3.3 Reference process model for single task 3.4 Reference process models for complex activities 3.5 Process Pool 3.6 Top-down automatic detailing of project schedules 3.7 Simulation model formalism 3.8 Fundamental design concepts and application scope 4 Data Integration between simulation and construction Project models 4.1 Data integration between BIM models and simulation models 4.1.1 Transformation of IFC models to Graph models 4.1.2 Checking BIM model quality 4.1.3 Filtering of BIM models 4.1.4 Semantic enrichment of BIM models 4.1.5 Reference process models and BIM models 4.2 Reference Process Models and resources models 4.3 Process models and productivity factors 5 Construction Simulation Toolkit 5.1 System architecture and implementation 5.2 Basic steps to create a CST simulation model 5.3 CST Simulation components 5.3.1 Input components 5.3.2 Process components 5.3.3 Output components 5.3.4 Logistic components 5.3.5 Collaboration platform ProSIM 6 Case Studies and Validation 6.1 Verification and Validation of Simulation Models 6.2 Verification and validation techniques for simulation models 6.3 Case study 1: generic planning model 6.4 Case study 2: high rise building 6.4.1 Scenario I: effect of changing number of workers on structural work duration 6.4.2 Scenario II: simulation of structural work on operation level 6.4.3 Scenario III: automatic generation of detailed project schedule 6.5 Case study 3: airport terminal building 6.5.1 Multimodel Container 6.5.2 Scenario I: automatic generation of detailed project schedule 6.5.3 Scenario II: Find the minimal project duration 6.5.4 Scenario III: construction work for a single floor 7 Conclusions and Future Research 7.1 Conclusions 7.2 Outlook of the possible future research topics 7.2.1 Integration with real data collecting 7.2.2 Multi-criteria optimisation 7.2.3 Extend the control-flow and resource patterns 7.2.4 Consideration of further structure domains 7.2.5 Considering of space allocation and space conflicts 8 Appendix - Scripts 9 Appendix B - Reference Process Models 9.1 Reference Process Models for structural work 9.1.1 Wall 9.1.2 Roof 9.1.3 Foundations 9.1.4 Concrete work 9.1.5 Top-Down RPMs for structural work in a work section 10 Appendix E 10.1 Basic elements of simulation models in Plant Simulation 10.2 Material Flow Objects 11 References

<p>The paper investigates the challenges of consolidating beneficiary participation in the planning and implementation of projects, the effects on project outcomes and the implications for community based development. It examines one of such projects in Sekondi- Takoradi Metropolis of Ghana by assessing the entire planning and implementation of the project, the participatory mechanisms used and the current state of the project in terms of its sustainability. The paper critically investigates a broad arena of literature relating to the evolution of the participatory concept and its relation to development planning and management. It further explores some of the critiques leveled against the concept. The paper argues further that beneficiary participation in Community Based Development Projects (CBDPs) in Ghana is a challenge because of the internal rigidities associated with the use of the concept. It explains through evidence from the analyzed data that understanding the strategies for the participatory process as well as the socio dynamics of the beneficiaries involved is important in ensuring positive project outcomes.</p>

This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit.   The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes.   The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process. The importance of testing the profitability of the idea is also being discussed. The interviews also indicated that the pre-project phase is not linear but rather transactional and that the original alternatives presented to the client lead to new client desires and requirements.
