Construction 3D BIM-based knowledge management system: a case study

AbstractKnowledge management (KM) is the organization, creation, sharing and flow of knowledge within organizations. Knowledge can be shared and reused among involved engineers and experts to improve a construction process and reduce the time and cost of solving problems. This paper proposes a new and practical methodology to capture and represent construction project knowledge by using a Building Information Modeling (BIM) approach. Using BIM approach, users can make visual knowledge management in the 3D Computer-aided Design (CAD) environment. This study addresses the application of knowledge management in the construction phase of construction projects and proposes a Construction BIM-based Knowledge Management (CBIMKM) system for general contractors. The CBIMKM is then applied in selected case studies of a construction building project in Taiwan to verify our proposed methodology and demonstrate the effectiveness of sharing knowledge in the 3D environment. By applying the BIM approach, all participants...

Enhancing Construction Interface Management Using Multilevel Interface Matrix Approach

Abstract Many interfaces typically exist in the construction phase of a project. Since project participants usually fail to share interface information, most interfaces are difficult to solve effectively during that phase. Furthermore, future activities might not be implemented based on changes made by predecessors. In practice, failure to manage interfaces may result in additional work or in low project performance. In order to manage construction interfaces effectively, this study proposes the novel Multilevel Interface (MI) Matrix approach to enhance interface management during the construction phase of construction projects. By using the MI matrix approach, construction interface issues will be tracked and man-aged easily and effectively. Furthermore, this study develops a construction web matrix-based interface management (WMIM) system integrated with the proposed MI Matrix approach. The MI matrix approach and WMIM system are applied to a pilot test to illustrate how to support interface management d...

Use of BIM approach to enhance construction interface management: a case study

AbstractMany interface events and problems occur during the construction phase of construction projects, such that tracking and controlling these are essential to construction management. Interface management (IM) has become the most important aspect of a sound project management strategy. IM affects project cost, scheduling, and quality both directly and indirectly in construction projects. Interface or changed events can be identified and tracked using IM, such that construction processes can be improved, while minimizing rework and reducing total project duration. Despite the many studies and discussions in academic and practical literature, systematic approaches and information platforms for managing interface events and problems during the construction are lacking. This study tracks and manages interface events using novel three-dimensional (3D) interface maps integrated into the building information modelling (BIM) approach. The BIM approach, which is utilized to retain interface information in a di...

The analysis of BOT strategies based on game theory – case study on Taiwan's high speed railway project

Abstract Uncertainty in a contract for some BOT (Build-Operate-Transfer) projects may allow an opportunistic developer to take advantage of information asymmetrical factors, long-term external changes, and agency dilemma to request renegotiation and to alter the contact after it has been awarded. Such requests often entrap the government in hold-up problems and result in improper payments to the developers and may even create general public dissatisfaction with a project. In this paper, the Game Theory model is used to analyze the Taiwan High Speed Railroad project to examine how developers implement different strategies at the various stages of a project to alter the contracts conditions in order to continually creating competitive advantage after they have been awarded the contract. This project developer is now facing serious financial difficulties. In this study, the financial information on the Taiwan High Speed Railroad operations was used as the foundation for conducting a simulation to calculate ...

Developing as-built BIM model process management system for general contractors: A case study

AbstractAs the application of building information modeling (BIM) becomes more common, BIM model management becomes necessary and important to enhance the effectiveness of BIM implementation for a general contractor (GC) during the construction phase. Implementation of BIM models in the construction phase, which typically involves participants from different fields, often has numerous BIM-related interfaces and problems. Therefore, feedback from the most recent as-built model tracking and BIM model problems are essential for BIM process management (BIM PM) in the construction field. BIM PM has become the most important aspect of a sound as-built BIM model management strategy. Changes in as-built BIM models should be identified, updated, and tracked for BIM PM, such that version management of as-built BIM models can be improved, while minimizing rework and reducing as-built BIM models development duration. Systematic approaches and information on management platforms for enhancing BIM PM during the constru...

Use of Support Vector Regression to Improve Computational Efficiency of Stochastic Time-Cost Trade-Off

AbstractStochastic time-cost trade-off has been a popular object of investigation in past decades because there are uncertain factors that can be considered when determining the appropriate trade-off between project completion time and cost. Previous studies, however, have implemented a double loop procedure, which performs optimization in the outer loop and simulation in the inner loop. The double loop procedure is ponderous because it requires an unacceptably long computation time (taking hours or days), even for a small to medium project. The present study proposes an integrated system that converts the double loop to single loops,thereby dramatically reducing computation time. This is done by incorporating a support vector regression model to obtain a decision function, which will be used to replace the time-consuming Monte Carlo simulation to evaluate the objective function values for individual solutions. With the objective function values, a multiobjective particle swarm optimization algorithm is d...

Developing construction defect management system using BIM technology in quality inspection

AbstractDefect management (DM) for quality inspection (QI) is a major strategy employed by general contractors to enhance construction management of building projects. However, there are significant issues in construction DM in standard practice that affects quality inspection, including protracted procedures, data entry redundancies, confusion, and inefficient information management. Recognition of these construction DM issues, this paper proposes a new and practical approach that applies Building Information Modeling (BIM) technology to quality inspection and defect management. Specifically, BIM digitally contains precise geometry and relevant data needed to support building structures to describe 3D object-oriented CAD. Using BIM technology, this study proposes a BIM-based Defect Management (BIMDM) system by on-site quality managers during the construction phase. The intended approach integrates web and BIM technologies in the BIMDM system to illustrate and analyze defect information at the jobsite in ...

A decision support model for scheduling exhibition projects in art museums

The main purpose of scheduling exhibition projects for art museums is to provide the visitors with more exhibitions and to utilize the galleries as fully as possible. Because the combinations of possible exhibitions for all galleries at any given time are numerous, it is difficult for the art museums planner to make an optimal decision. Therefore, this paper developed a decision support model with genetic algorithms, called SCHEMA (SCHeduling Exhibitions for Museum of Art). In the model the galleries are the resource which the exhibitions utilize in the sequence of their priority values. The models evaluation shows to be significantly effective in planning time, percent usage of the gallery, and the number of exhibitions scheduled. Because all the complex computations are done by the model, the decision making process of the scheduling stage is speeded up considerably.

Developing RFID-Based Instruments Maintenance Management in Construction Lab

Maintenance management is very important subject special in construction lab. To manage related information of equipments and instruments plays an important role in the view of construction lab management. Those equipments and instruments need high standard and requirement in precision and accuracy of tests. Managing maintenance work effectively is extremely difficult in construction lab owing to various equipments and instruments with different specification. Furthermore, it will take high cost to maintain those instruments in the good conditions for the test correctness. With the advent of the Internet, web-based information management solutions enable information dissemination and information sharing among related maintenance staff members. Generally, maintenance managers and staffs require access to the equipments and instruments location to handle inspection and maintenance work in construction lab. Usually, maintenance staffs generally use sheets of paper to handle various types of maintenance information, including checklists, specification, and maintenance procedure. Consequently, there is serious rework progress regarding the data capture and entry in maintenance progress. In order to enhance the effectiveness of inspection and maintenance work in construction lab, this study presents a novel system called Mobile RFID-based Maintenance Management (M-RFIDMM) system for the acquisition and tracing of lab equipments and instruments maintenance information on locations and providing an equipments and instruments maintains information sharing platform among all participants using web technology and RFID-enabled PDAs. Integrating promising information technologies such as RFID-enabled PDAs, Radio Frequency Identification (RFID) scanning and data entry mechanisms, can help improve the effectiveness and convenience of information flow in the maintenance management. The primary objectives of this study include (1) applying such a system that integrates RFID technology with RFID-enabled PDAs to increase the efficiency of equipments and instruments inspection and maintenance data collection, and (2) designing a web-based portal for equipments and instruments management and control, providing real-time information and wireless communication between offices and instruments locations. The MRFIDMM is then applied in a construction lab in Taiwan to verify our proposed methodology and demonstrate the effectiveness of maintenance progress in construction lab. The combined results demonstrate that, an M-RFIDMM system can be a useful webbased lab maintenance management platform by utilizing the RFID approach and web
