Interpesssnal communication of price-related information at the project inception stage: an interview survey

Abstract: The premise UPOn which this gaper is based is that, within the context of information transfer, there has been insufficient examination of the interpersonal communication function. This paper is concerned with the effectiveness of the interpersonal communication process associated with certain communication media utilised in the provision of price-related information at the inception stage of the building procurement process. More specifically, it deals with communication aspects of quantity surveyors’ engagement letters and documentation, clients’ briefs, and the language of building price forecasting. The paper documents the results of an interview survey concerning the opinions of clients, architects and quantity surveyors.

Implementation of single building modelling technologies into themanagement phase of the property cycle

Abstract: This paper brings together work carried out by Guy Hazlehurst, Stephen Drewer and RodenBuxton at the University of the West of England on the concept of the Single Building Model andresearch by Terry Pitt and George Griffith on the management of complex healthcare facilities,'Healthcare FM'. The central aim of the research has been to utilise advanced 3D, object modelsof complex buildings not only as repositories for 3D, 2D graphics, data and intelligence, but to actas 'information brokers'. The concept of the single building model has effectively evolved toprovide a spatial database that has the inherent potential to act as the spine of a 'heterogeneous'system. This spine links the sub-systems that enable complex processes throughout the life of thebuilding to be modelled.This paper will seek to address the issues of systems integration, through the creation andapplication of Single Building Modelling technologies, during the post occupancy stage of thebuilding process. Modelling complex buildings and estates at a time long after the facilities wereoriginally conceived, designed and built posits a set of unique issues that do not arguably arisewhen such models evolve through the incremental processes of inception, design and construction.It will be argued that the principal issues are those of data compatibility and the level of detailrequired within the 'ex-post' single building model to deliver optimum benefit to the owners andmanagers of complex buildings. The research issues identified by the production andimplementation of such a model within a Hospital's existing building management will bediscussed. Although the example cited in this paper is a healthcare building the points raisedwithin it arguably apply to any significant property or estate.

Analyzing Capacity of BIM Tools to Support Data Use across Project Lifecycle

Abstract: The lifecycle of a building project, from design through inception and facility management, comprises multiple project management processes where data and information are defined and generated. This information is often only developed and stored in a format and at a level of detail sufficient for the process that it was created, leading to the reworking of information to support later project processes. In order to support processes throughout the project lifecycle, there needs to be a method of structuring and storing information that takes into account information needs at later project processes. This paper examines the use of BIM tools and the methods used to record, recall, manipulate, and generate information to support processes through the project lifecycle. The benefit of a structured information system based upon process information needs is explored as to how it can enhance the use of information within a BIM to support lifecycle processes.

First experiences with an inception support modeller for the building and construction industry

Abstract: Inception and very early design of complex building and construction projects requires a large number of decisions to be made, considered, rejected, changed, or confirmed. Many views on the project co-exist at the same time, requiring complex communications and access to complicated knowledge covering the complete project and product life cycles.Balancing the results of this non-monotonic decision taking process is (1) not a trivial task and (2) very important for the project outcome, as most of the product and construction process characteristics (like performance and cost) will largely be fixed. Further optimizations in later design stages will only be marginally possible.In order to support the inception and very early design of complex construction project we are developing an Inception Support Modeler (ISM) that guides the user through the decision taking process. Decision taking is supported by a combined PDT (Product Data Technology) and KT (Knowledge Technology) approach. The focus of the current modeler is on the inception of technical buildings, like Power or Process Plant Buildings, Factory Buildings, Hospitals and such. The product model and the knowledge base are developed in co-operation with the Brite- Euram CONCUR project.The paper reports about the first test case of the ISM. As part of a demonstration in CONCUR, the ISM has been filled with Business Objects and Business Logic concerning the inception of a simple Turbine Building.

IT support for the very early design of buildings and civil engineering works

Abstract: Despite a general agreement about the importance of very early design decisions (various sources estimate that between 60% to 80% of the total project costs are determined during this stage), the very early design stage of building and civil engineering projects is not yet adequately supported by IT. The paper focusses on the problems that are causing the lack of IT support and reports on a possible solution based on the application of Product Data Technology (PDT) and Knowledge Engineering. The paper will show some initial experience with the development and application of an Inception Modeller that implements ideas from the General AEC Reference Model (GARM) as proposed by Wim Gieling in 1988. The development takes place in co-operation with the Brite-Euram CONCUR-project. The system concentrates on the inception and very early design of technical buildings, i.e. buildings in which equipment plays a major role, like power plant buildings, hospitals, factories, etc. The basic idea is to support the choice and elaboration of Technical Solutions that fulfil the requirements of Functional Units. The knowledge base is structured according to a FU-TS decomposition, or Hamburger model, of the building. A knowledge acquisition tool based on the same Hamburger model is under development and will be explained in some detail in the final paper. The system is implemented in Java, using Clips as the knowledge engine and VRML for the visualization. Though it is probably still too early to draw any definitive conclusions, it looks as if the structure provided by the FU-TS decomposition is ideal for very early design support. It provides a means to capture and re-use knowledge of successful earlier designs, thus providing a mechanism still missing in the building and construction industry.

United States Air Force Milcon Transformation: Building Information Modeling Case Studies

Abstract: The United States Air Force manages approximately $2B of traditional military construction (MILCON) per year in a typical portfolio of 100-150 projects. In Fiscal Year, 2010, the Air Force’s MILCON authority having jurisdiction, the Air Force Center for Engineering and the Environment (AFCEE) revised its standard design instruction to supplement how it managed and directed MILCON. One of the primary differences was a requirement for all vertical construction to be designed through a Building Information Modeling (BIM) approach. There were two pilot projects to assess Air Force BIM implementation. First, one project case study explored impact on typical MILCON project management practices. The HQ CENTCOM facility implemented a BIM-based approach on a standard design-bid-build project at MacDill Air Force Base, FL. A second project case study explored cutting edge research methodologies that used the BIM for facility optimization on a LEED-platinum facility. Specifically, the Tyndall Air Force Base Fitness Center targeted energy efficiency. The facility’s Electronic Management Control System (EMCS) monitored pure consumption, solar photovoltaic (PV) power meter pulse output, and solar hot water recovery systems using Digital Energy Monitors (DEM) tied to the BIM via an exported database file via the EMCS server. Lastly, AFCEE partnered with Onuma to manage and leverage their new BIM-based designs to afford greater collaboration from inception onward for USAF facilities worldwide. This research investigates owners’ lessons learned and designers’ experiences related with the initiative under MILCON Transformation, as well as the implications for shaping future USAF MILCON management and design optimization.

Advanced electronic document management solutions for the construction industry: the CONDOR project

Abstract: The paper is based on research carried out within the CONDOR project funded under the European ESPRIT programme. CONDOR is specifically concerned with defining the working practices, processes, techniques, tools and technical infrastructure to allow the construction industry to progress from its current position towards a large scale, computer integrated industry. Furthermore, the project aims at bridging the gap between current information systems and future ones, and provides a migration path from document-based to model-based approaches to information representation and structuring. After a brief overview of the state of the art of Electronic Document Management systems in the construction industry, the paper presents the overall CONDOR system architecture, along with a detailed description of its components. The latter include: * the CONDOR Integration Services (implemented as a class library in the CONDOR demonstrator); * the CONDOR API: it defines the services to allow on the one hand, inter-working between the project’s legacy EDM systems, and on the other, semantic linking between different documents and between documents and other information objects (the precise services that are provided have been largely determined from the results of the analysis conducted by the project’s end-users), * the Adaptors: they provide the mapping between the CONDOR API and each of the document and object management systems to be integrated. It is worth pointing out that the CONDOR system is designed to be open enough to coexist and inter-operate with construction legacy applications, as with other existing and emerging distributed components, in a seamless way. These legacy applications can then, in turn, take advantage of the generic, and construction specific, advanced document management functionality developed within the CONDOR project. The paper then presents the conceptual models that support the CONDOR system, this includes the CONDOR Information Management Model (CIMM). The CIMM is concerned with the management of information produced within a project’s lifecycle, from inception to demolition. Whilst the CIMM is developed within the frame of the construction industry, it is aimed to be generic enough to be used in any other industrial context. CONDOR addresses four primary issues that are central to information management: ownership, rights and responsibilities; versioning of information; schema evolution ; and recording of intent behind decisions leading to information. Finally, the paper presents one of the project end-user’s implementation strategy of the Condor approach. The CONDOR project is ongoing and supported by a user interest group, which involves representatives from a variety of non-construction industry companies all over Europe.

Supporting the inception stage of building projects with real-time value versus cost evaluations

Abstract: "The paper discusses early results of an inception support modeller that uses state of the art Product Data Technology (PDT) and Knowledge Technology (KT). The modeller under development provides Facility owners with the opportunity to create and evaluate a number of alternative solutions for their accomodation by stating their requirements like i.e. functional requirements and resources like i.e. available money and location. By applying knowledge rules, case rules and default values information gaps will be closed in order to generate more detailed alternatives. This process assures the availability of just enough product information to perform an evaluation of the performance and the cost, and gives the Facility owner a better view on a realistic solution of his requirements. Using a 3D frontend in combination with a requirements language which is easy to comprehend the client can input his requirements on different aspects of the project like project related aspects (cash flow, type of contract), building environment related aspects (availabity of public transport or green), functional related aspects and components related aspects. Feedback wil be given like cost evaluations, construction time and performance values like energy usage, exspected lifetime, running cost, and maintenance cost. The working of the tool will be illustrated by a case, a Hospital Inception Modeller."

Achieving BIM And CIM Implementation Through Quality Management

Abstract: This paper presents a studied proposition that the domain of Building Information Modeling (BIM) and Civil Information Modeling (CIM) is Quality Management. This proposition is approached from a thorough review of BIM and CIM capabilities, the operation actualization in design and construction, the individual value added and extracted throughout the workflow process, and the value added to the owner in delivering an accurate model. The paper first presents the value added and received by the creation and use of information modeling; secondly the paper addresses the workflows associated with the information model’s production, from model inception to archival record; it follows this with a discussion on the alignment of the model with various operational focuses with the cycle of model documentation, utilization, model maintenance, commissioning, and owner transfer. The paper closes with insight into Quality Management as the most appropriate champion forwarding the integration of the information modeling for maximum value added in the development of the built facility.
