Collaboration processes A State of the Art
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The key objective of InPro is to define and support a new way of working with integrateddesign from a life cycle perspective, capturing client requirements and collaboration betweenstakeholders during the early design phase of a construction project. This phasestarts with the first client contact and ends with the delivery of a design proposal, withrecognisable functions, visualised for easy understanding and with a cost calculation tosupport the clients' go/no-go decision.The aim of Work Package 2 is to develop model-based and knowledge-based workingmethods for the Early Design phase. This will result in a systematic integration of lifecycledesign processes in new construction or renovation of buildings, taking into accountthe added values for society/citizens, clients/users, and the construction sector. ThisWork Package will also propose a framework for the collaboration process between involvedparties.The aim of Task 2.2 "Collaboration Processes" is to develop this framework for collaborationin the Early Design process, where all partners share information in a common OpenInformation Environment delivered by WP5 and add knowledge to the project. Thisframework of collaboration is a concept related to the needs of shared guidelines in orderto work efficiently together, generally defined in a contract. This framework will answerto the main question:How to create concurrent and iterative working processes with clear decisionmilestones?and includes other key questions:How to create functional working groups that represent different competenciesor backgrounds, including conflict resolution conceptsHow to to establish trustHow to balance between formal and informal communication channelsHow to communicate design changes in a virtual building model between concurrentlyworking design teams, e.g. by managing, categorising and highlightingdesign changesHow to reuse knowledgeIt also includes project and contractual issues management, progress monitoring, strategiesfor delegation of responsibility, methods for risk assessment and strategies for continuousimprovements based on measured Key Performance Indicators developed in Task1.3.

A Smart Decision Making Framework for Building Information Models
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report describes a systematic approach to evaluate the performance of virtual building designs and processes. The reference for the evaluation is a set of goals critical for the project success. Within the Smart Decision Making Framework (DMF) these goals arecaptured from the main stakeholders using the concept of Key Performance Indicators(KPIs). KPI evaluations are relative by nature since they base on the deviation of actuallymeasured figures to initially set optimum figures for specific criteria. They can be formulatedfor objective as well as for subjective criteria. Smart DMF further proposes to discretelydefine the relation between the tolerance level for deviations and a respectivedimensionless rating, using so called utility functions. To incorporate tolerances is necessarysince project goals are in praxis often conflictive in their effects on each other;therefore it is generally seldom possible to achieve all goals to 100% at the same time.Since design processes are always characterized by such trade-offs, these have to bereflected by the concept. The following steps summarize the Smart DMF process:Assessment of the critical design valuesTransformation of the critical values into KPIs using utility functions to describe the relation of model-based measurements and performance ratingsDefinition of priorities using a pair wise comparison algorithm from the Analytic Hierarchy Process (AHP)Generation of virtual design alternatives or options plus required analysis dataCapturing the measurements from the virtual models to calculate the KPI figuresand calculating the KPI specific performanceLinear calculation of the total ratings for each alternativeVisual representation of the evaluation resultsChapter 1 in this report explains the context and scope of this research. It also characterizesthe requirements of the application objective to an evaluation framework. Chapter 2-4 describe the methods and processes of Smart DMF from the definition of KPIs via constitutingpriorities to represent the results of the evaluation in an easy to understand wayto project team members. With the application scenario in chapter 5 we hope to furtherexplain the framework and its actual use on real-world projects to practitioners. KPI examples and a discussion of various decision making methods in the Appendix A round this report enabling readers to apply Smart DMF within their projects and organizations.Smart DMF combines the concepts of KPIs, Multi-Attribute-Utility-Theory (MAUT) and pair wise comparison taken from AHP in a new way. The result is a framework tailored for the requirements of a model based design process for building design. On the one hand theframework can be used to measure all aspects relevant for the lifecycle of a building. The proof of concept has been shown with the application of Smart DMF on an energy designprocess. Further examples will be prepared in other InPro projects, such as T.2.4 “Lifecycledesign process” and T. 5.3 “Performance Evaluation”. On the other hand, the overall KPI score could be considered as a measure for the overall design performance.
