Indonesian contractors’ performance in managing IT: critical success factors, assessment model, and benchmarking system

Abstract: Indonesian contractors have entered the information age by adopting information technologies (IT) to improve the efficiency and effectiveness of their business processes. Yet many contractors that have adopted IT face problems related to how to get the best of the adoption and how to reap benefits from the investment. The problem lays in the poor management of IT by contractors including strategic planning, design, implementation, maintenance, evaluation and human resource management processes. This paper discusses three studies conducted to measure the performance of contractors in managing IT. Critical success factors in managing IT were identified from a survey of large contractors and an assessment model was developed based on these factors and implemented by the same con-tractors. The results of the assessment showed that, in practice, IT is still used merely as supporting tools and there are many limitations to its current usage in contractors’ environment. A benchmarking tool for Indonesian contractors to improve their performance in managing IT investments was further developed. A benchmarking case study is discussed in this paper as a real example of the benefit that a contractor can get from the three studies related to measurement of Indonesian contractors’ performance in managing IT.

IS tools for knowledge management in public construction projects

Abstract: This paper focuses on the possible tools of knowledge management by exploring offered, needed and wanted knowledge. We study knowledge management by exploring how the tools are utilized currently in case projects in Finland and how new tools could improve the processes. We also aim to study what kind of obstacles there are for IS tools utilization. New ways of organizing work are resisted and people very soon become cynical and unintended consequences of techno change failure hinder the success of the new change efforts. It is important to be aware of this and change efforts should be implemented in project work by letting the practitioners effect the change and select the way of working. We also found that often ICT have positive effects on the challenges but that often there is a critical mass problem, where the benefits are not yet gained if there are not sufficient users.

Towards a Taxonomy of Cyber-Physical System Applications in Construction

Abstract: Cyber-physical systems (CPS) facilitate the integration of physical processes through offering embedded computation and communication. Through this embedded communication and computation, CPS has the ability to add more intelligence to physical processes and provides effective means for bidirectional coordination between physical entities and their virtual representations. CPS is still considered to be a nascent technology in many industries including construction, and there are many challenges yet to be addressed. However, there is growing interest in this technology and several applications of CPS in improving various construction processes have been proposed in the last few years. This paper classifies current CPS applications presented in the literature for construction projects and accordingly presents a preliminary taxonomy of CPS applications in Construction. To this end, the different components and methods that are required for the application of CPS in construction are characterized and classified and the areas that require further research are identified. It is expected that this taxonomy and its mapping to relevant systems will be highly useful for further development of CPS for improving construction processes.

A new approach to integration of design and production

Abstract: The building industry in all consists of several parties representing design, engineering, construction and systems, materials or components industry. Because of organisational segregation there is a great need of process integration in construction. Nowaday designers are not yet able to produce product models, so contractors should create company models themselves from information provided by designers (paper drawings or CAD-tiles). Integration between design and production applications requires standardization of transfer file format or database structures. In this paper a new approach for the construction integration is introduced and examples of the implemention are shown.

Modelling the Cost of Corporate Implementation of Building Information Modelling

Abstract: The popularity of BIM has improved in the past years. However, its adoption and implementation rates are still slow. Apart from latent limitations regarding yet undefined market drivers; many potential BIM users are still speculative because of a number of concerns. Arguably, there is need for defining comprehensive frameworks for initiating and servicing BIM adoption and sustainable implementation, both in term of cost and non-cost indices. A process model for BIM implementation is discussed using different organization structures. This is indexed on skilling, hardware, software, on-costs, indirect costs and marketing costs. Conclusions are drawn on the benefits and limitations of implementing this model.

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.

Extranet technology in a small and medium size construction companies

Abstract: Project extranets have been used in construction for the last 10 years and research shows that there are many benefits to their use. However, their use has not been taken on by all firms. A project extranet as a web-based portal allows subscribers to securely share information over the internet. This research looks into the drivers and barriers faced by small and medium sized contractor and house builder companies in terms of employing extranets on construction projects.The objectives of this research are to identify the characteristics of contractor and house builder companies in the UK, to identify the extent to which project extranets are used and to investigate the drivers and barriers to contractor and house builder companies of using project extranets. Extranets have the potential to improve traditional processes by improving communication and document and information transfer between the vast numbers of organisations that can be involved on a construction project. Yet it is found that many contractor and house builder organisation are facing barriers such as the perceived expense of the systems and time required for implementation and training. The construction industry needs to overcome these perceived barriers in order to reap the benefits that extranets can provide. This research forms a scoping study as a basis for further research into the drivers and barriers of extranets for the wider industry. Semi-structure interviews were used as the primary method of data collection, companies’ policy documents and other literature were also reviewed to assist the entire data collection process.

A Low-Cost Internet Connection for Intelligent Appliances of Buildings

Abstract: To date, the Internet has been a network connecting mostly desktop PCs, but soon all kinds of intelligent devices containing a small microprocessor will exchange data over the Internet. This will have a big impact on buildings and their technical systems, which now include a number of processor-based devices. Internet connectivity implies a totally new way to control and manage these devices. The potential benefits will be significant. Therefore, the need to design low-cost Internet appliances is worldwide today, and many commercial products are already available. This paper proposes a new technical approach to connect small processor devices to the Internet. The approach makes possible a connection both through the Public Switched Telephone Network (PSTN) and the Global Systems for Mobile Communications (GSM) network. The connection is based on networking software programmed in the processor device and a gateway server, which together transfer data between the PSTN and other communication networks. The data communication utilizes the Short Message Service (SMS) and the Extended Machine Interface (EMI) protocol. Besides the low cost, the proposed system has several benefits, such as uncomplicated structure and operation, standardized data transfer, and an ability to be embedded in an 8-bit processor device. Yet, the approach does not require high-speed data communication. Thus, it is especially suitable for applications controlling slow and non-critical building processes. The proposed system was demonstrated by designing a microprocessor device interfaced to an Air Handling Unit (AHU). Sensor data from the AHU was transferred to the Internet through the PSTN and the GSM networks. In addition, a Web-user interface was created for the remote control of the AHU. The results of the pilot project were encouraging and will be used as a basis for further development of the system

LOCATION-BASED MICRO-MILESTONES FAIR SUB-CONTRACTOR PAYMENT

Abstract: This paper introduces the new concept of location-based micro-milestones and argues for their use in achieving fair payment for subcontractors. It integrates location-based management (LBM) theory and Business Process Management (utilising YAWL: Yet Another Workflow Language) to illustrate how location-based BIMs can be utilised for the effective and fair payment systems. It outlines the rationale for linking LBM and YAWL methodologies to develop a BIM alternative solution to a traditional industry problem of late payment for sub-contractors. Location-Based Management methodologies are now available in the powerful scheduling and control software (Vico Office by Vico Software). Originally developed in Finland, it has now become part of the BIM movement through integration into 5D environments (3D + time + cost), using location-based quantity data (from 3D BIM) and location-based scheduling (4D). While LBM is being rapidly adopted in industry, expansion of theory in workflow knowledge based on data from real projects remains limited. YAWL has a well-established foundation based on concurrency theory and workflow patterns derived from research. It is informed by experiences with languages supported by contemporary BPM systems and it has a formal semantics. Linking these two methodologies could provide a BIM solution to the problem of late payment to sub-contractors. The YAWL support environment could be extended to provide a workable interface for auto-generating construction payment processes from digital models based on LBM defined micro-milestones. The visualisation of the YAWL interface and related workflows could be used to both inform the analysis and to communicate the results. This paper suggests a study to obtain proof of concept that LBM and YAWL can create an auto-generated certification and payment system for sub-contractors. Results could be configurable reference process models and workable prototype tools that trigger immediate payment of completed work according to the completion of location-based micro-milestones.

A proposed IT-based approach for managing the construction brief effectively

Abstract: A wide range of problems are encountered during the briefing stage of a construction project. There is little guidance and support for clients, whilst designers have difficulties both in capturing clients’ needs and conveying conceptual design options to them. There is a central difficulty, associated with language, communication and the exchange of information between clients and design teams, which is now gaining widespread acknowledgement. The CoBrITe (LINK/IDAC UK funded) project argues that the construction industry has yet to exploit the potential of IT systems to assist both parties during this critical phase. This is in contrast to later stages of design and construction where computer-based techniques and systems are commonplace. The overall aim of the CoBrITe project is to improve the briefing process through more efficient and effective use of existing and emerging information technologies that can support client and design teams. This aim translates into the following objectives: · highlight shortfalls and best practice by reviewing information management techniques and the use of IT during briefing; · integrate recent/current research projects concerned with briefing and form a research network; · access potential users’ needs in terms of use and diversity in both small-medium and large projects, focusing on the five key improvement areas (Link IDAC 88); · identify promising systems/products that could assist the Key Improvement Areas by conduct an audit of existing enabling information technologies (including interfaces); · position the IT products within the framework of briefing and design processes in Level 2 of the IMI Process Protocol and the IAI Business Process Model, to inform their development; · identify specific IT tools and methods for the five improvement areas; · produce a prototype integration environment for the management of briefing and design information; · deploy effectively the proposed approach by re-engineering the briefing process redesign (within the industrial companies involved in the consortium). The proposed paper will give a comprehensive overview of the CoBrITe project, including an analysis of the briefing practices and information requirement within the industrial partners of the project. A description of the CoBrITe briefing process model will be given. The paper also gives a description of the CoBrITe system architecture, including the application programming interface supporting the CoBrITe infrastructure. The latter proposes a framework that integrates a set of proprietary and commercial software applications aimed at supporting the briefing process. Finally, the CoBrITe demonstrator will be presented. The latter has been developed within the context of the Wythenshaw hospital managed by one of the industrial partners: WS Atkins.
