Integrated product and process modelling for facility management

Abstract: The economic situation in many enterprises is becoming more and more difficult. To stay competitive all these enterpises need to increase the performance of buildings for greater productivity, health, and safety of occupants, to improve the reliability of facility operation and the level of occupant satisfaction with their work environment, and to decrease the cost and environmental impact of facility operation. The purpose of this article is to present an information system that will allow owners, operators and the public to gain benefits from substantially improved performance of their facilities. The Facility Management System will use advanced information technology to provide life cycle information for all relevant key processes. Existing organization structures, division of responsibility and computer support tools are only partially suitable to meet the new requirements. New ideas are required not only for business processes but also for computer-supported data processing tools. This article identifies and structures the business processes for the use phase of a constructed facility and it includes the different points of view necessary to define the requirements for a multifunctional information support.

LCAdesign: an integrated approach to automatic eco-efficiency assessment of commercial buildings

Abstract: Buildings consume resources and energy, contribute to pollution of our air, water and soil, impact the health and well-being of populations and constitute an important part of the built environment in which we live. The ability to assess their design with a view to reducing that impact automatically from their 3D CAD representations enables building design professionals to make informed decisions on the environmental impact of building structures. Contemporary 3D object-oriented CAD files contain a wealth of building information. LCADesign has been designed as a fully integrated approach for automated eco-efficiency assessment of commercial buildings direct from 3D CAD. LCADesign accesses the 3D CAD detail through Industry Foundation Classes (IFCs) - the international standard file format for defining architectural and constructional CAD graphic data as 3D real-world objects - to permit construction professionals to interrogate these intelligent drawing objects for analysis of the performance of a design. The automated take-off provides quantities of all building components whose specific production processes, logistics and raw material inputs, where necessary, are identified to calculate a complete list of quantities for all products such as concrete, steel, timber, plastic etc and combines this information with the life cycle inventory database, to estimate key internationally recognised environmental indicators such as CML, EPS and Eco-indicator 99. This paper outlines the key modules of LCADesign and their role in delivering an automated eco-efficiency assessment for commercial buildings.

Safety Risk Assessment in Construction Projects Using Information Models

Abstract: The identification of safety risks in construction sites has been a major concern of project managers who need to develop proactive safety plans to reduce accident and health related risks. This paper proposes a method which combines BIM technology, virtual reality tools, and Monte Carlo simulation to reveal possible accident conditions and to assess the probability of accident occurrence with the aim to promote safety management and accident reduction. Within the context of construction projects, the construction site is dynamically modelled employing BIM software. A programming language (Visual C #) is used to represent the human/machinery movements in the virtual environment. Finally, Monte Carlo simulation is performed to analyse specific work scenarios which may lead to hazardous conditions and assess the safety level. The aim is to link the risk output with the BIM model and to develop a heat map of accident risk throughout the project allowing, thus, prompt and effective implementation of preventive measures for accident reduction or avoidance.

Implementation of a Preference Monitoring Application for office Building Occupants

Abstract: Buildings should provide a level of comfort that is acceptable to majority of the occupants and enhance their health and productivity. When indoor environmental conditions are not as good as expected, occupants sometimes make adjustments. In order to capture and monitor occupant preferences and occupant behavior indoors, a feedback system- Preference Monitoring Application (PMA) was created. With the PMA, energy use behavior and occupant preference data are collected on a continuous basis while energy consumption and indoor environmental parameters are being monitored separately in a building. The PMA was developed by identifying the values that are important to building occupants and following recommendations from other indoor environmental quality surveys. It is a simple application that captures satisfaction with temperature, lighting, indoor air quality and other parameters that influence occupant comfort and behavior on a continuous basis by using human input. A comparison of the feedback from 10 occupants in an office building in Pennsylvania, USA and 14 occupants in an office building in Doha, Qatar over 7 months are presented in this paper. This can enable the use of actual data to develop occupant profiles to improve occupant satisfaction.

Comparing Feature Matching Algorithms for Measuring In-Plane Strains on Civil Infrastructures

Abstract: Maintaining structural integrity of civil infrastructures such as bridges and tunnels is always an essential task for civil engineers. Collapse or damage of these infrastructures may lead to a tremendous amount of painful injuries, casualties, and societal losses. This paper reported the work on evaluating optimal feature matching algorithms for development of visual sensing-based techniques to measure in-plane deflections and strains in order to facilitate monitoring and evaluation of integrity of civil infrastructures in a cost-effective way. A series of experiments were conducted in which three algorithms Digital Image Correlation (DIC), Scale-Invariant Feature Transform (SIFT) and Speeded-Up Robust Features (SURF) were compared. The result indicated that DIC has superiority among the three algorithms. To further assess the accuracy of DIC, a high-speed industrial camera was then used to capture a series of continuous image frames of deformed real-world scenarios. The DIC algorithm was adopted in the feature detection and tracking process, and in-plane displacement and strains were calculated and compared with the ground truth. The result indicated that the DIC-based method can achieve highly accurate performance in measuring in-plane deflections and strains for civil infrastructures and holds potential to the development of visual sensing enabled structural health monitoring.
