Using Interactive Workspaces for Team Design Project Meetings

Abstract: An Interactive Collaboration Laboratory (ICL) has been established at the University of New Brunswick (UNB) to research the application of interactive information and communication environments for the architectural, engineering, and construction (AEC) industry. This paper provides a quick overview of the laboratory within the wider context of interactive collaborative workspaces. It identifies opportunities to enhance information communication, and group decision-making offered by the laboratory, and focuses on lessons learned to date from its use. The paper reports on a survey conducted among final year undergraduate students who used the environment over the course of three months for their senior design project meetings. A questionnaire was distributed to those students to investigate the impact of the environment upon the effectiveness of their meetings and decisions, the issues and processes where the environment was more (or less) useful, and the context within which the environment and tools were used. The questionnaire also investigated the impact of the environment and its tools upon their project, the quality of their work, and their overall satisfaction. Students found the laboratory to be specifically useful at the preliminary design stage when designing, viewing, and analyzing the site and building layouts of their projects, and determining the project’s sustainability requirements, and targets. The laboratory enabled student groups to view information from different perspectives, access remote information, and save captured information instantaneously. It also enabled them to collaborate more effectively, make more educated decisions, make better use of their time, produce higher quality work, and develop among them a relationship of trust, respect and mutual understanding. Investigating how best to use the lab’s technology to serve their needs, occasionally slowed down their progress and distracted them at times from focusing on their work.

A LIFECYCLE FRAMEWORK FOR USING BIM IN HEALTHCARE FACILITY MANAGEMENT

Abstract: Facility Management (FM) is important for healthcare environments to provide adequate and safe treatment to patients by maintaining the physical environment. FM activities are challenged by being disconnected from other processes within a facility’s lifecycle. Within healthcare, this disconnect is compounded by insufficient communication with clinical personnel about concurrent clinical operations. Insufficient communication can lead to added risk to patient safety and additional cost to healthcare procedures. This paper describes research on identifying the information across the facility lifecycle and within the facility management and operation stage that are needed to support FM activities in healthcare environments. This information will be used to develop an ontology of integrated FM and clinical information for improving the quality of care in a healthcare setting. The ontology will be linked to a BIM. The ontology will ensure that needed information for facility operations is recorded throughout the lifecycle of the facility and allow facility managers quick access to better organized information. Focus will be on giving an overview of the methods used for determining information needs for FM activities through case study analysis. Case studies are identified through interviews with FM and clinical personnel as well as through literature review. Select cases are documented with Business Process Model Notation (BPMN) allowing for separation of steps and actors within each case. Information needs for each of the steps is determined and overlaid onto the BPMN diagrams. Lastly, the source of each information types is determined. Future work will take the information types, and their origins, determined through this analysis and apply it to an ontology. The ontology will support a BIM-based system for capturing information throughout the lifecycle of the facility in support of the operation and maintenance of the facility.

Improving highway asset management with RFID technology

Abstract: Radio Frequency Identification (RFID) technology mobilizes data through radio wave transmission with RFID tags. Two RFID systems, short-range and long-range, showed potential in assisting highway asset management programs of the Virginia Department of Transportation (VDOT) by providing access to condition data in the field; both systems were previously analyzed for tag retrieval and data storage. In this research, the short-range system is further analyzed to: evaluate affordable tag security methods, assist in highway asset location visualization, evaluate tag performance in weather conditions, and explore optimal tag attachment to highway mile markers. The long-range RFID system is further analyzed to: establish a wireless broadband-based system-data interface, perform a market analysis for an optimal wireless internet card for the interface, evaluate performance in predicted implementation scenarios, explore a combination of both RFID systems, and perform a system cost analysis. Results yield an overall positive impact on highway asset management using RFID technology.

Expert system technology in construction management

Abstract: This paper describes the development of a micro computer aid driven by a suite of programs which allow the design identified solution for a given building project to be transposed into information reflecting the construction solution. The 'modus operandi' of the computer aid is the use of an Expert System which can access and manipulate data contained in a data base and to submit back to a data base, for subsequent user retrieval, information about the particular building project under consideration at various stages during its realization. The system is initiated by the creation of a design situation model which is held in a relational data base in the form of information concerning the descriptions and quantities of the finished work required to achieve the building project. The Expert System, through the logic contained in the inference engine, organises the design stated situation model describing the construction solution in terms of construction activities, the resources needed and their cost implications. Thus the system is intended to provide an interface between the product related design solution and the process related construction solution and has the aim of aiding the following: 1. Resource and financial management by design team 2. Resource and financial management by the construction team

Mobile augmented reality, an advanced tool for the construction sector

Abstract: Augmented reality is nowadays a novel technology that is acquiring great relevancy as a research area. This technology complements the perception and interaction with the real world and allows placing the user in a real environment augmented with additional information generated by computer. Throughout last years it is increasing the interest and the results reached in the technologies of augmented reality on desktop environments. However there are numerous environments of application of these technologies that require mobility of the user, need of access to the in-formation at any time and any place, in these cases there becomes necessary the utilization of mobile devices. Construc-tion Sector is a clear example. The development of mobile computing solutions is crucial in construction sites. The per-manent change of the site (workers, activities, work place, etc.) implies that users need to get permanently updated in-formation. Mobile computing solutions make this information available without reducing or disturbing the mobility and agility of the users. In this paper we present the mobile augmented reality as an advanced and innovative tool for the construction sector. This technology has a high potential to achieve more sustainability, profitability and higher quality level in this sector. It is structured in two main sections. An initial one that analyses the current status of the augmented reality technologies using mobile devices and describes the benefits provided by these technologies, the most recent challenges achieved, the novel applications and the problems not yet solved. And a second one that analyses the poten-tial applications of the mobile augmented reality in the construction sector and describes a scenario in which the use of mobile computing solutions makes possible to increase efficiency and safety in construction sites.

Pattern-Based Generation of 4D-Schedules for Robust Construction Management

Abstract: The creation of construction schedules is a time-consuming manual process. While project planning depends on many tasks and parameters, the quality of schedules highly relates on the engineers' experience and the access to reliable, historical project data. While knowledge applied from software can assist an engineer, the main shortcoming of current tools is the separation in generating building information and construction process models. Proposed is a knowledge-based system that automatically generates 4D-schedules based on building information models. Patterns are used to generate a process model for repetitive work flows, such as placing formwork, reinforcing, and concreting. Pattern-enriched attributes, i.e. the topology of the building structure, are automatically applied to objects in the model. Resource allocation, such as varying the performance factors or the amount of work crews, becomes possible. Such analysis can still be evaluated and exported in the format of traditional Gantt-diagrams or color-coded 4D-schedules and the construction process model can be used for detailed scheduling, construction time control, and time-based quantity evaluations. The developed approach was validated for the concreting work of a 12-story tall office building under construction. Preliminary results indicate gains in accuracy and efficiency of the developed approach compared to the traditional scheduling process.

Linked Data for Cross-Domain Constraint Information Sharing in LNG Construction

Abstract: Reliable construction plans are vital for effective collaboration across a projectÕs design, procurement and construction. Numerous constraints arising from engineering, supply chains and construction site are the main factors affecting planning reliability. Currently, there is not an efficient way to access all these constraint information because they are stored in various systems and managed by multiple domain participants. This paper aims to utilise Linked Data Technology to enable links to be set between data (i.e. constraint information) in different systems and therefore connect these systems into a single global data space. A prototype of the proposed approach was developed and tested on a sample LNG project.

BIM Big Data System Architecture for Asset Management: A Conceptual Framework

Abstract: Effective decision making in the AEC/FM industry has been based increasingly on an exponential growth of data extracted from different sources and technologies. It has been argued that Building Information Modelling (BIM) can handle this information efficiently, acting as a data pool where data can be stored, managed and integrated. Indeed, a BIM platform based on cloud computing and Big Data can manage the storage and flow of data, as well as extract knowledge from Geographical Information Systems (GIS), Internet of Things (IoT), asset management, energy management and materials and resources databases. Furthermore, it can also provide an opportunity for multiple users to view, access and edit the data in 3D environment. This paper describes the requirements and different components of a BIM Big Data platform for facilitating management of building assets. This is achieved by firstly, conducting a critical peer review to ascertain Big Data definitions and stages, and also to define the critical BIM requirements for the Big Data platform. At the crux, this paper presents a conceptual framework for developing a Big Data platform for BIM which incorporates suitable tools and techniques needed to export, store, analyse and visualise BIM data.

Constructability knowledge-intensive database system

Abstract: Generally, lessons learned in the construction, operation, and maintenance of a facility are not effectively fed back as input to the design and construction phases of new projects. Traditional methods of collecting and disseminating lessons-learned in the construction of projects have enjoyed limited success due to: (1) the unreliable communication channels between construction experts and practitioners, (2) the lack of a meaningful classification system, (3) the unmanageable format that made it difficult to access, retrieve and update the potentially enormous volume of lessons, (4) the difficulty of integrating new systems into existing operations and procedures, and (5) the focus on failures or incidents, rather than on both positive and negative experiences with constructed facilities. If the experience and lessons learned at the construction site could be captured and incorporated into a dynamic, interactive, knowledge based information system, then great benefits could be realized as this information is utilized in the design and construction of future facilities. Constructability and maintainability can be enhanced, more efficient construction methods can be utilized, facility quality and safety can be maximized and total life cycle costs can be minimized.This paper presents a knowledge-intensive database system for constructability improvement. Construction lessons were collected; a framework for classifying, storing and disseminating lessons was designed; and a prototype system was developed, tested and validated. This system can be used: (1) as an assistant and decision-making tool by engineers and foremen of contractors, and (2) as an educational and training tool by undergraduate and graduate students of civil engineering at Kuwait University.

Visual product chronology as a solution for accessing building product model data

Abstract: Building product modelling technology is principally aiming for solutions which are capturing the data of gradually developing buildings. In simple terms these solutions can be characterised as storages where the most recent data and its updates exist. At the moment IFC standard is providing a common starting point for sharing building product model data between various applications. Having this as a starting point one major current challenge is to build methods and practical tools for accessing building product models. Here the term access means both data input and different analyses over building product model data. For example, the user needs to find out all building components where changes have appeared during certain period and visualise those in an appropriate level of detail. It is considered that these types of operations shall provide a true basis for wide acceptance and impact of building product modelling technology. Visual Product Chronology is an application, which can be used for linking data from various sources with the objects of building product model and for analysing the content of the resultant data storage. Development of Visual Product Chronology is proving improved understanding of various problems and their potential solutions when we are on way to develop applications enabling versatile but an easy access of building product model data.
