Service oriented approach to facility management using extended building information modelling

Facility management (FM), from a service oriented approach, addresses the functions and requirements of different services such as energy management, space planning and security service. Different service requires different information to meet the needs arising from the service. Object-based Building Information Modelling (BIM) is limited to support FM services; though this technology is able to generate 3D models that semantically represent facility’s information dynamically over the lifecycle of a building. This paper presents a semiotics-inspired framework to extend BIM from a service-oriented perspective. The extended BIM, which specifies FM services and required information, will be able to express building service information in the right format for the right purposes. The service oriented approach concerns pragmatic aspect of building’s information beyond semantic level. The pragmatics defines and provides context for utilisation of building’s information. Semiotics theory adopted in this paper is to address pragmatic issues of utilisation of BIM for FM services.

A metodologia BIM-FM aplicada a um caso prático

O crescente aumento da consciencialização da importância da fase de operação e manutenção, bem como a amplificação que a metodologia Building Information Modelling (BIM) tem obtido nos últimos anos, sugere uma necessidade de alterar a atual abordagem da gestão das instalações de forma a dotá-la das mais recentes inovações tecnológicas como seja a utilização do BIM. Os Building Information Models apresentam as características ideais para a integração da gestão das instalações, não só pela visualização do edifício, mas sobretudo pela potencialidade que a base de dados oferece, com informação referente a cada um dos componentes presentes e suas relações. O âmbito deste trabalho envolve assim a integração da gestão das instalações com o modelo BIM criado, representativo do edifício em estudo. Este trabalho começa com as definições do âmbito e dos objetivos que são propostos no Capítulo 1. No Capítulo 2, é elaborada uma pesquisa sobre o estado da arte atual de cada uma das metodologias BIM e FM, de forma a tomar conhecimento dos seus conceitos principais. Foi feito também um levantamento no campo do BIM-FM de forma a apurar as atuais soluções tecnológicas existentes, a forma como é feita a sua troca de informação e também alguns casos em que esta metodologia foi aplicada. Com base na informação recolhida sobre as metodologias e também nos casos práticos estudados, é realizado no Capítulo 3, capítulo central deste trabalho, a aplicação prática. A realização desta aplicação é dividida por 3 fases principais. Numa primeira fase é especificada e recolhida a informação necessária de ser obtida para a realização do modelo e a posterior aplicação do FM. A escolha da informação a recolher é feita ponderando todos os fatores existentes, mas de forma a cumprir os requisitos pedidos. Numa segunda fase, assente na compilação de informação recolhida anteriormente, realiza-se o modelo do edifício. A modelação, de forma a seguir o método de trabalho BIM é realizada por especialidades, sendo numa primeira fase realizada a especialidade de arquitetura e posteriormente, utilizando esse modelo como base, é feita a modelação das especialidades de águas, águas residuais, AVAC e eletricidade. Esta escolha foi também estimulada pela organização do software utilizado para a modelação, por módulos. Na última fase da aplicação do caso prático a informação inserida na fase de modelação do edifício é exportada para o software de FM, neste caso em específico, o IBM Maximo. Para a exportação destes dados foi utilizado o formato Construction Operations Building Information Exchange (COBie), de forma a garantir a integridade e conformidade da informação transferida. No Capítulo 4 deste trabalho são abordadas as especificidades relativas à informação existente, à modelação e à troca de dados entre o software de modelação e o software utilizado na gestão do edifício. São também sugeridos alguns temas para futuros desenvolvimentos com o intuito de ampliação dos campos de FM com o uso do modelo. O BIM-FM é um tema emergente na atualidade do BIM, sendo a sua utilização encarada como uma mais-valia ao processo BIM. A compilação da informação durante a fase de projeto e execução, aliada à existência do modelo torna a implementação do FM com o modelo BIM como uma sequência natural.

EVALUATING INFRASTRUCTURE PERFORMANCE TO ASSIST FACILITY MANAGEMENT TOWARD SUSTAINABLE SYSTEMS

Civil infrastructure provides essential services for the development of both society and economy. It is very important to manage systems efficiently to ensure sound performance. However, there are challenges in information extraction from available data, which also necessitates the establishment of methodologies and frameworks to assist stakeholders in the decision making process. This research proposes methodologies to evaluate systems performance by maximizing the use of available information, in an effort to build and maintain sustainable systems. Under the guidance of problem formulation from a holistic view proposed by Mukherjee and Muga, this research specifically investigates problem solving methods that measure and analyze metrics to support decision making. Failures are inevitable in system management. A methodology is developed to describe arrival pattern of failures in order to assist engineers in failure rescues and budget prioritization especially when funding is limited. It reveals that blockage arrivals are not totally random. Smaller meaningful subsets show good random behavior. Additional overtime failure rate is analyzed by applying existing reliability models and non-parametric approaches. A scheme is further proposed to depict rates over the lifetime of a given facility system. Further analysis of sub-data sets is also performed with the discussion of context reduction. Infrastructure condition is another important indicator of systems performance. The challenges in predicting facility condition are the transition probability estimates and model sensitivity analysis. Methods are proposed to estimate transition probabilities by investigating long term behavior of the model and the relationship between transition rates and probabilities. To integrate heterogeneities, model sensitivity is performed for the application of non-homogeneous Markov chains model. Scenarios are investigated by assuming transition probabilities follow a Weibull regressed function and fall within an interval estimate. For each scenario, multiple cases are simulated using a Monte Carlo simulation. Results show that variations on the outputs are sensitive to the probability regression. While for the interval estimate, outputs have similar variations to the inputs. Life cycle cost analysis and life cycle assessment of a sewer system are performed comparing three different pipe types, which are reinforced concrete pipe (RCP) and non-reinforced concrete pipe (NRCP), and vitrified clay pipe (VCP). Life cycle cost analysis is performed for material extraction, construction and rehabilitation phases. In the rehabilitation phase, Markov chains model is applied in the support of rehabilitation strategy. In the life cycle assessment, the Economic Input-Output Life Cycle Assessment (EIO-LCA) tools are used in estimating environmental emissions for all three phases. Emissions are then compared quantitatively among alternatives to support decision making.

People and Facility Management. The team: the main asset of any management

From the moment we enter a large office building until we leave it, we receive a lot of attentions served by the management of services to the user. However, it is usually quite inappreciable the work that is being developed to keep things running smoothly.The services provided in a building are carried out by people. However, we often tend to forget these people when we talk about the tasks that make that a building operates properly 24 hours a day, 365 days a year.But, for example, what would happen if one day the service provided by the reception in a large building did not function as it should? What would it be like if one day the person performing the service of maintenance of the building's cleaning were not at his post? How would the working day develop if there were not a correct air handling system?People are the foundation of the proper functioning of a building. The work of the Facilities Manager and the Facility Management is the management of their functions: the responsible management of the team.

A facilities maintenance management process based on degradation prediction using sensed data

Energy efficiency and user comfort have recently become priorities in the Facility Management (FM) sector. This has resulted in the use of innovative building components, such as thermal solar panels, heat pumps, etc., as they have potential to provide better performance, energy savings and increased user comfort. However, as the complexity of components increases, the requirement for maintenance management also increases. The standard routine for building maintenance is inspection which results in repairs or replacement when a fault is found. This routine leads to unnecessary inspections which have a cost with respect to downtime of a component and work hours. This research proposes an alternative routine: performing building maintenance at the point in time when the component is degrading and requires maintenance, thus reducing the frequency of unnecessary inspections. This thesis demonstrates that statistical techniques can be used as part of a maintenance management methodology to invoke maintenance before failure occurs. The proposed FM process is presented through a scenario utilising current Building Information Modelling (BIM) technology and innovative contractual and organisational models. This FM scenario supports a Degradation based Maintenance (DbM) scheduling methodology, implemented using two statistical techniques, Particle Filters (PFs) and Gaussian Processes (GPs). DbM consists of extracting and tracking a degradation metric for a component. Limits for the degradation metric are identified based on one of a number of proposed processes. These processes determine the limits based on the maturity of the historical information available. DbM is implemented for three case study components: a heat exchanger; a heat pump; and a set of bearings. The identified degradation points for each case study, from a PF, a GP and a hybrid (PF and GP combined) DbM implementation are assessed against known degradation points. The GP implementations are successful for all components. For the PF implementations, the results presented in this thesis find that the extracted metrics and limits identify degradation occurrences accurately for components which are in continuous operation. For components which have seasonal operational periods, the PF may wrongly identify degradation. The GP performs more robustly than the PF, but the PF, on average, results in fewer false positives. The hybrid implementations, which are a combination of GP and PF results, are successful for 2 of 3 case studies and are not affected by seasonal data. Overall, DbM is effectively applied for the three case study components. The accuracy of the implementations is dependant on the relationships modelled by the PF and GP, and on the type and quantity of data available. This novel maintenance process can improve equipment performance and reduce energy wastage from BSCs operation.

Quincy and Torch Lake Railroad engine house facility management and interpretive plan

The “Quincy & Torch Lake Railroad Engine House Facility Management and Interpretive Plan" was designed to serve as a guide to aid the Quincy Mine Hoist Association in their efforts to restore and interpret historic railroad resources under their stewardship. Early searches for existing management and interpretive plans demonstrated that similar plans were primarily produced by the National Park Service and were intended to guide large scale heritage sites that consist of a variety of cultural resources. This project adapts concepts found in those large scale management and interpretive site plans, to guide small scale site management, restoration, and interpretive projects. The document presents a three stage, second phase restoration process. Each stage of development is guided by a series of management and interpretive goals and objectives which were set for the engine house facility.

A evolução de um modelo BIM de construção para gestão de empreendimentos

A implementação da evolução tecnológica no setor da construção tem se caracterizado pelo aparecimento de novas tecnologias que dinamizam os processos de troca de informação entre os vários intervenientes no ciclo de vida do empreendimento. O surgimento da tecnologia Building Information Modeling - BIM assente na modelação paramétrica e na interoperabilidade suportada em ficheiros de padrão aberto (IFC) pressupõem um novo paradigma na forma como são tratados os processos de troca de informação entre os vários intervenientes no ciclo de vida dos empreendimentos. Com base no BIM o Construction Operations Building Information Exchange – COBie, é outra tecnologia recente que recolhe informações não geométricas associadas ao modelo e em conjunto com a informação geométrica produzida pelo BIM fazem parte dos documentos de entrega para a fase Facility Management – FM. O objetivo da presente dissertação centrou-se no estudo da evolução de um modelo BIM de construção para a gestão de empreendimento. Foi desenvolvido o estudo de um modelo protótipo que incidiu na utilização de softwares para verificação e aplicação das tecnologias COBie e BIM e também foi sincronizado com a fase FM. Da aplicação dos requisitos COBie e modelação BIM foram extraídas informações geométricas e não geométricas preenchidas nas folhas de trabalho COBie. As principais conclusões do estudo realizado foram que as tecnologias COBie e BIM têm pouca implantação a nível nacional e a sua integração dinamiza os processos, reduzindo custos e aumentando a qualidade da informação fornecida.

Metodi e strumenti di Facilty Management: una proposta di integrazione tra Piano di Manutenzione e Fascicolo dell’Opera nel caso della Grande Distribuzione Organizzata

Gli ultimi 10 anni hanno visto un crescente aumento delle richieste di fornitura di servizi legati alla manutenzione edilizia da parte della Grande Distribuzione Organizzata; la domanda è quella di servizi riconducibili al Facility Management, ovvero rapporti basati sul raggiungimento di standard qualitativi predefiniti in sede contrattuale e garanzia di intervento 24h/24. Nella prima parte del progetto di tesi viene inquadrata la disciplina del FM, le motivazioni, gli strumenti e gli attori coinvolti. Dopo un excursus normativo sulla manutenzione in Italia, una classificazione delle tipologie di intervento manutentivo e una valutazione sull’incidenza della manutenzione nel Life Cycle Cost, viene effettuata un’analisi delle modalità interoperative del FM applicato alla manutenzione edilizia nel caso della GDO. La tesi è stata svolta nell'ambito di un tirocinio in azienda, il che ha permesso alla laureanda di affrontare il caso di studio di un contratto di Global Service con un’importante catena di grande distribuzione, e di utilizzare un software gestionale (PlaNet) con il quale viene tenuta traccia, per ogni punto vendita, degli interventi manutentivi e della loro localizzazione nell’edificio. Questo permette di avere un quadro completo degli interventi, con modalità di attuazione già note, e garantisce una gestione più efficace delle chiamate, seguite tramite un modulo di Call Center integrato. La tesi esamina criticamente i principali documenti di riferimento per l’opera collegati alla manutenzione: il Piano di Manutenzione e il Fascicolo dell’Opera, evidenziando i limiti legati alla non completezza delle informazioni fornite. L’obbiettivo finale della tesi è quello di proporre un documento integrativo tra il Piano di Manutenzione e il Fascicolo, al fine di snellire il flusso informativo e creare un documento di riferimento completo ed esaustivo, che integra sia gli aspetti tecnici delle modalità manutentive, sia le prescrizioni sulla sicurezza.

Management of Traffic Control — A Computer Oriented Approach

Traffic Management system (TMS) comprises four major sub systems: The Network Database Management system for information to the passengers, Transit Facility Management System for service, planning, and scheduling vehicle and crews, Congestion Management System for traffic forecasting and planning, Safety Management System concerned with safety aspects of passengers and Environment. This work has opened a rather wide frame work of model structures for application on traffic. The facets of these theories are so wide that it seems impossible to present all necessary models in this work. However it could be deduced from the study that the best Traffic Management System is that whichis realistic in all aspects is easy to understand is easy to apply As it is practically difficult to device an ideal fool—proof model, the attempt here has been to make some progress-in that direction.
