Investigations in the BICT project of state-of-the-art ICT for industrialization of house building processes

Abstract: The research presented here is part of a project named BICT, ”Evaluation of benefits of ICT for the indus-trialization of project and product processes in the construction industry”. Its overall objective is to establish a mutual understanding between the construction industry and R&D actors of the needs and possibilities of ICT. The project is a cooperative effort between Swedish and French researchers and industry representatives within the EraBuild program. It includes an investigation of the processes and ICT tools in a representative house building project, together with a study of the State-of-the-Art of ICT for immediate, short and medium term uptake. This paper presents the main results of the State-of-the-Art study with specific focus on: - Visualization and coordination using digital mock-ups of 3D models; - Model based quantity take-off; - Integration of applications for product design; - Reuse of experience based knowledge. The presented study concludes that the use of integrated 3D applications must be introduced early in the project lifecy-cle in order to pave the way for the use of object-oriented information in downstream processes. This requires common standards for 3D based deliveries developed in cooperation between industry and R&D actors through joint analyses of actual information management both in industrialised partnering-like processes, and fully industrial building proc-esses.

ALIGNING INTERESTS KEY TO DEVELOPING TRUST IN DEPLOYING COLLABORATIVE TECHNOLOGIES IN CONSTRUCTION

Abstract: The importance of trust in construction is well documented especially when the desire is to encourage people to work as a team and to collaborate on construction projects using diverse information technologies. Trust is an integral component of effective teams, successful partnering, and implementing new technology. Building and maintaining trust between contracting parties can lower costs, improve performance and minimize disputes. Construction literature has discussed the types of trust, dimensions of trust and trust building tools. However, a need exists to further explore the importance of aligning the interests of contracting parties. Aligning interests are in addition to the traditional critical success factors for construction projects (profit, cost, schedule, quality). Trust is a state of mind that is strengthened or weakened as each party’s hierarchical and subjective interests are supported or challenged. This paper presents an integrated trust model and describes strategies aimed to build and maintain trust in construction when using collaborative technologies. The model further demonstrates that project managers using a specified strategy and system to elicit, monitor and align collaborative interests , in addition to other traditional measures of project success, can improve the likelihood of building and maintaining trust in deploying collaborative technologies in construction.

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 ADOPTION AND USE OF ICT IN CONSTRUCTION PROJECTS THROUGH THE LENS OF CONTEXT, ACTORS AND TECHNOLOGY

Abstract: In the literature on construction related ICT no distinction is usually made between ICT use in the permanent organization and the temporary organization forming the building and construction projects. By drawing on the rich body of literature on organizational and managerial aspects of ICT the aim of the paper is to investigate how the interplay between contextual elements, actors’ frames of reference, and the ICT influence the adoption and use of ICT in building and construction projects. This objective will be pursued by an analysis of an ongoing study of ICT use in the Swedish building and construction sector, including semi-structured interviews and an ethnographic inspired study of a partnering project worth 50 million €. It is concluded that project based mode of organizing, with the prime focus on time and costs, creates a conflict with the process of introduction and development of ICT use that is characterised by ambiguity and indefinite duration in time that goes beyond the termination of a project. Unless immediate benefits are perceived by the adoption and use of an ICT application, it will not be used. This conflict can probably not wholly be solved, instead the industry has to learn to live with it and create spaces for innovation of ICT-mediated changes.

Reverse propagation of data for building management

Abstract: Lifetime data for the management of buildings is becoming more feasible and is now expected by more facilities managers. It should be possible to extract the data related to the building fabric and systems from that generated during design and construction. For this to be just what the users require and in the form they require it, depends upon their involvement at an early stage of a project. Reverse propagation can then enable their wishes to influence the data collected so that redundant data is not produced and does not cause confusion. New forms of procurement such as partnering, allow this early involvement; alternatively there must be standards to define the general form of management data. In Denmark the CIS-CAD system defines a simple format being tested on a series of projects. It extracts information needed for statutory authorities and management, and examples are given based on continuing experience of its use. The principles of reverse propagation are discussed and the trend in databases to allow input from both ends of the process. This will eventually allow a more precise and economic definition of the building model and core data needed for management.

Monitoring Communication in Partnering Projects

Abstract: This report is a summary of a two year research project carried out by the IT byg group at BYG. DTU for the Danish government agencies Erhvervsfremmestyrelsen and By- og Bolig-ministeriet. The objectives were to collect data on the use of IT by the PPB housing consortia, a development project to test out various innovations, to map communications between the partners, and compare IT usage with their original proposals. Data was collected on communications in housing projects in the period June 1999- Aug 2000. The original PPB proposals were made in 1994/5 but there have been breaks in the flow of projects, and information technology has gone through much change since then. Use of Email has taken over from post and fax, and Project Webs have been developed in most consortia. Consortium members' policies have dominated the choice of management and logistics software, restricted compatibility in the consortia, and limited willingness to share data. Greater involvement by the client, and more sharing of equity, would have encouraged adoption of common IT systems and created more trust for data sharing between partners. PPB projects have allowed consortium members to test out new technologies but, in general, the IT systems used have been similar to those which the larger firms use elsewhere. Vertical integration has been limited by lack of experience and technology in smaller firms. In future, access to Project Webs from mobile devices should help use by all partners from any location. In all the projects studied, and in spite of the introduction of Email and Project Webs, the ratio of non-IT communications to IT varied from 0.8 to 4.6. When problems need to be solved rapidly there appears to be a tendency to revert to traditional means of communication - meetings, telephone and fax.

Monitoring use of communications on a partneringproject

Abstract: The 'Process and product development in the building industry' (PPB) projectin Denmark has acted as a test bed for various types of innovation in buildingsocial housing since 1995. Four consortia developed methods of design andconstruction that were tested on a series of similar housing projects. Thedevelopment project was supported by the Ministries of Industry and Housing,who commissioned the ITbyg group to monitor use of information technology.Partnering between the designers and constructors, should have been verysuitable for electronic communication. DTU studied various media used duringboth design and construction stages. It carried out Social Network Analysis ofthe number of messages, and partners involved, in different methods of sharingdata. This is a case study of one consortium and describes its communicationsover a two-week period and their use to solve a design problem. It found thatelectronic communication was little used to solve the problem, but Email wasgenerally used and Project Webs were being tried. However even 5 years ofpartnering is too short for a project team to change its methods of working.

Refocusing collaboration technologies in the construction value chain

Abstract: Modern construction processes rely on the contributions of diverse functional specialists working in inter-organisational teams to design, cost, procure and manage modern construction projects. In the UK the Latham report has focused attention on eliminating the adversarial nature of the construction industry. Project specific partnering is one procurement route being taken by leading client and main contracting organisations to improve the interpersonal relationships of those organisations involved in the construction process. In order to support the cultural changes recommended by Latham, the necessary communications infrastructure must be put in place. As well as a high bandwidth communications infrastructure, commonly available collaborative tools must be used to allow disparate cross-functional virtual teams to exchange information.

Integrated design system to support partnering practice in the water industry

Abstract: "CONTEXT The Egan report on the UK construction has identified the traditional competitive tendering as one of the main causes for the poor performance of the industry. It recommends the use of supply chain Partnering to deliver valuable performance improvements. Partnering involves two or more organisations working together to improve performance through agreeing mutual objectives, devising a way for resolving any disputes and committing themselves to continuous improvement, measuring progress and sharing the gains. To realise the full potential of partnering it is necessary to implement an effective and reliable information infrastructure in support of integrated information management and exchange in the project process. This paper describes an on-going research project, GALLICON, funded by the Department of Environment, Transport and Regions (DETR) and a consortium of companies who are involved in the design and construction of water treatment plants in the UK. Its main aim is to develop an integrated design system which facilitates the collaboration and information sharing between partnering organisations during the design of water treatment plants. OBJECTIVES AND METHODOLOGY The challenge for this study is not only to develop new technical solutions but also to ensure the solutions can bring immediate benefits to water treatment projects in practice. To achieve the research aim, works are being carried out in the following areas: Business process analysis. Case studies are used to analyse the business process of the design of water treatment plants. The IDEF0 formalism is adopted to decompose the sub-processes and their inter-dependence. The analysis also identified the functional requirements of the targeted integrated design system to support the main activities of layout design, specification, cost estimation and project planning. Prototype development. A rapid prototype approach is used to implement an integrated design system prototype for water treatment plants. The prototype has the capability of supporting interdisciplinary information exchange and distributed collaboration. Benchmarking benefits. To ascertain the business benefits of the developed system, a benchmarking case study will be conducted in which the design practice will be compared using the new system and the traditional systems. RESULTS AND CONCLUSIONS GALLICON is an on-going research project. At present, an initial prototype has been developed which consists of an integrated project database, a Process Manager and interfaces to four third party AEC software packages of CAD, Cost Estimating, Project Planning and VRML browser. The database provides a central consistent repository for project information. The included AEC applications communicate with the database through purpose-built data mapping interfaces. The operation of the system is controlled by the Process Manager implemented on the basis of business process models developed through the business process analysis task. GALLICON is an attempt to apply integrated project database to water treatment projects. This paper described the prototyping experience of GALLICON, including product and process modelling, implementation of the integrated project database, and benefits benchmarking of such a system."
