From BIM Models to Integrated Energy Efficiency Applications for Industrial Facilities

Abstract: Raised interest in efficient use of available resources in industrial facilities prompts for software-tools to predict and manage energy demand of the whole system. An integrated approach considering all energy consumption contributors, classified into building, energy system, production and logistics, is developed within the research project Balanced Manufacturing (BaMa). Thereby BIM models of industrial spaces containing valuable information are used for creating a comprehensive representation of building-related aspects in a hybrid simulation environment, able to assess manufacturing and auxiliary energy demands.For testing the applicability of this integrated hybrid approach, a prototype is developed based on an actual use case. The simplification procedure is presented and the energy performance results are compared with that of an established building energy modelling software, discussing advantages and limitations. Essential information that needs to be transferred from the BIM model is clarified and prioritised.

Product modeling for construction management

Abstract: With the ever-increasing use of computer technologies for managing the information involved in business processes, information standardization has been identified as an important step towards improving the efficiency and effectiveness of these processes. Over the past two decades, many research and development projects have worked towards standardizing existing information in the architecture, engineering, and construction (AEC) industry. Many information models at different levels have been proposed and many prototypes have been developed. The major part of this effort has focused on modeling product information in AEC projects (as opposed to process, organizational, or other project information), and has concentrated on the designer's perspective. Our interest, however, is from the perspective of project managers. Although project management introduces a spectrum of process information that governs the act of constructing a project, the product information that describes the facility itself is still central. Yet this product information is not explicitly represented in existing project management software such as estimating and scheduling software. This paper outlines the dimensions of a research project aimed at product modeling for project management. It discusses some of the specific requirements of product models for the purpose of supporting project management functionality. The paper also describes a framework that has been devised for categorizing project management functions.

Automation of technical information systems

Abstract: The paper is a synthesis of two research works: .Automation of Technical Information Systemsu and 4lassification Systems for the Construction Industry)), which have been funded by Progetto Finaliuato Edilizia (Italian National Council of Research). The design of buildings currently requires a huge amount of processed data, due to various procedural routines required for obtaining the necessary authorizations. Such documents are usually drawn up on paper: information technology allows t o perform in a simpler and systematic way all data managed and to enhance process efficiency in the construction industry.

Requirements Transformation in Construction Design

Abstract: Transformation of performance requirements to technical solutions and production parameters is central for architects and engineers in the design process. The delivery of a new low-carbon economy in Europe puts pressure on the construction industry to reduce the energy consumption in the building stock.Energy requirements are often regulated in national standards or recommended by branch organisations. New methods and tools has been developed to simulate and analyse the energy consumption in buildings and support the transformation of requirements for technical solutions. Today industrialised housing companies suffers from low efficiency in the design and information flow creating bottlenecks in the production process. Matching the energy requirements is of great interest for the construction industry and especially for companies developing industrialised housing system that often have control over the whole manufacturing process. Therefore are three different national standards for energy requirements tested on a industrialised housing system and evaluated in an ICT –environment that supports the design process for industrialised construction. The result of the research shows that the transformation of energy requirements to technical solutions needs well defined design activities based on deliveries through the process. A well defined design process together with a building system is also the backbone for development of ICT support systems.

Keywords: Requirements transformation, energy standards, BIM support, PLCS, construction design

Redefinition of geometrical components to specify kinematically undetermined behaviour

Abstract: A method for the redefinition of geometrical design components, to be used for specifying kinematically undetermined behaviour, is presented. It starts with checking all line-line combinations for intersection or for a line-line combination being collinear. If an intersection has been found, it is used to generate additional lines such that both old lines are split up at their intersection, resulting in new lines. For lines being collinear a similar approach is followed. Hereafter, all line-area combinations are checked. If certain conditions are met, new intersection points and lines are generated in the area to provide new areas that split up the old area correctly. The procedures (line-line and line-area) are repeated until convergence. Finally, pattern recognition is used to find all areas from the intersection points within an original area. A C++ program and a number of examples verify the method and test its efficiency.

Dynamic System Architecture for Energy Efficient Building Operation: A Case Study of Kiptas Residential Building

Abstract: Buildings account for almost 40 percent of total energy in Europe. Holistic monitoring and analysis methodologies can reduce this by up to 30%. However, the adoption of monitoring and control systems for building management and control applications is hampered by the unavailability of appropriate tool environments. In this paper an integrated model-driven approach that automates the design from component to application level will be presented to provide optimized building operations. The aim is to create a holistic environment for wireless embedded monitoring and control systems to increase the efficiency of the overall system development process and to exploit their potential for reduction of building energy consumption. To reach this objective, new methods, tools and equipments were researched and integration methods covering integrated design, energy simulation models and data warehouse technologies were developed. The findings were applied to a residential building of Kiptas in Istanbul, Turkey and possible energy saving improvements were suggested.

Applying web services within the AEC industry: enabling semantic searching and information exchange through the digital linking of the knowledge base

Abstract: The Architecture, Engineering and Construction (AEC) industry is fragmented by professions separated by skill, stigma and distance. This fragmentation has created a dispersed knowledge base with knowledge gaps occurring within and between the professions. These knowledge gaps can only be overcome through the exchange of information and past experiences. Presently this exchange is reliant on manual communication, which has proven inefficient and open to misinterpretation. Web Services have been developed within the Information Technology industry to allow the crossplatform exchange of complex data. The application of this technology within the fragmented AEC industry holds significant potential. Research at the School of Architecture, Victoria University is exploring the integration of Web Services within existing databases to enable the searching, exchange and flexible presentation of relevant AEC information. Following industry feedback the aecBEDRock concept has been proposed which would enable the digital exchange and searching of valuable AEC data between professionals. The aecBEDRock concept utilizes the properties of Web Services and Industry Foundation Classes to create a digital AEC information framework that could bind the knowledge base of the industry. A stronger knowledge base would increase quality levels within the construction process through increased professional awareness and efficiency

DEVELOPMENT OF 5D-CAD BASED WORK PROCESS MODEL FOR AGED-HOUSING REVAMP PROJECTS

Abstract: A growing number of aged-housing building projects have become a great concern in Korean building industry nowadays. Until 2010, over 20 year-old housing units are reported to exceed more than one million. The aged-housing units are required to upgrade the performance on both structural and service issues. Compared to new building projects, revamp projects are relatively under developed in terms of construction management. For example, there is few guidance or detailed procedure which addresses the management practice in dealing with revamp projects. Therefore, new technologies are reluctantly implemented in the revamp projects without in-depth analysis on constructability and/or economic efficiency. The objective of this study is to provide a new approach in dealing with aged-housing revamp projects. By developing 5D- CAD based work process model, project managers are effectively informed of various data, i.e., building elements, network scheduling, and cost items. The 5D-CAD based decision making can also enhance the accuracy and promptness during project execution. The authors developed a standardized work process model in dealing with 5D-CAD modeling via Virtual ConstructionTM software. In addition, the model has been implemented to pilot aged-housing project for the purpose of validating the feasibility and applicability in real future projects. The proposed WBS(Work Breakdown Structure) and CBS(Cost Breakdown Structure) have been proved as useful tools for contractors who deal with aged-housing revamp projects under circumstances that there is few historical projects and few experienced personnel. Also, the study identified potential benefits and limitations of the 5D-CAD based construction process for revamp projects. Key findings from this study are as follows.- - - - -5D-CAD modeling is no more optional strategy in maximizing the project value. The error-free construction planning is much more essential in revamp projects. Sharing the real-time project information can overcome communication barriers. Collaborative works are definitely can benefit from 5D-CAD modelingFull scale usage of 5D-CAD modeling can be achieved by partnering contract

Understanding collective intelligence of construction project actors within a social network technology

Abstract: The disjointed group of actors who team up to work on a project constitutes a collective entity that is represented by social networks. The advancement of social network technologies enhances the researcher’s ability to understand individual and collective actions in order to effectively solve problems, make decisions, enrich knowledge, and reach consensus. These technologies enable the interfacing of actors who belong to the project network in order to facilitate the execution of project activities in collaboration. Since the aggregation of either individual or collective actors’ actions constitutes project activities, this research investigates the nature of these actions within a project organization, defined as a social structure that is represented as a project network through a web-enabled social network system. The actions form and reveal patterns that are scrutinized as routines within the project organizations. Of particular interest to this research are the potential gains in the efficiency, profits, and effectiveness of satisfactorily executed routines as an aggregation of actions. Moreover, this new kind of collective intelligence allows for the exploration of how actions performed through a web-enabled social network system may collectively act more intelligently than they have done before. It is critical, therefore, to scientifically explore actions within web-enabled social network environments through the study of routines executed by (1) single actors and (2) the aggregate of single individual actors. For this purpose, we developed theoretical constructs as framework for collective intelligence. Articulated by human-centered actions, four main constructs are involved in the framework: (1) social actors and communities of practice, (2) social structures, or organizations, (3) social objects as forms of representation of information, and (4) web-enabled social network technology. Examples of expected benefits are the facilitation of group strategies to reach decisions and control of group performance.

Keywords: Collective-intelligence, social networks, routines, social actors, communities of practice.

The suitability of IT as a tool to facilitate knowledge sharing in construction alliances

Abstract: The impact of environmental pressures has led many organisations to combine their resources and form alliances to develop and sustain competitiveness, profitability and long term growth. A review of the literature suggests that construction firms are not significantly different from others in their behaviour in meeting up the challenges imposed by the environment. Trends of forming strategic alliances therefore have embraced majority of the sectors of the construction industry. Not only do alliances act as vehicles for efficient project management but also they provide the opportunity for the organizations to share participants' knowledge. In this paper, which is based on an ongoing study, we argue that IT could be used as a tool to leverage shared knowledge in alliances to improve organisational outcomes. Indeed the traditional belief among people that "knowledge is power", which inhibited intraorganisational knowledge sharing, continues to act as a major constraint in alliance knowledge sharing too irrespective of the degree of IT use. In this paper we demonstrate the use of IT to complement other socialisation mechanisms to create new knowledge. In the process we investigate the effectiveness and efficiency of knowledge transfer mechanisms and link organisational outcomes to new knowledge creation.
