La presente tesis, tiene el propósito de aplicar una metodología de trabajo colaborativa para la gestión de proyectos de habilitación urbana de la Empresa La Fortaleza, a través de una simulación del producto final y que conforma una base de datos que permiten gestionar los elementos que forman parte de la infraestructura durante todo el ciclo de vida del proyecto. Esta metodología es BIM (Building Information Modeling) que nos permite mejorar la comprensión y comunicación del proyecto a través de su visualización en 3D, generando, de manera automática, toda la información necesaria para la gestión de obra compartiéndola a todos los involucrados en tiempo real. La habilitación urbana es el proceso de convertir un terreno rústico o eriazo en urbano, donde los predios de una zona urbana debidamente consolidada deben contar con servicios públicos domiciliarios, pistas, veredas e infraestructura vial, redes de agua, desagüe y alcantarillado y alumbrado público, cómo es el proyecto San Antonio de Pachacamac, Etapa 7 – Manchay. Objeto del estudio de la presente tesis. La tesis muestra cuan útil llega a ser el utilizar BIM en la gestión de un proyecto de habilitación urbana durante los procesos de diseño y construcción, identificando de esta manera las interferencias en la etapa de diseño; comparativamente con la metodología tradicional que en la etapa de construcción se identifican las interferencias que ocasionan los reprocesos, que cuantificados representan pérdidas económicas, ampliaciones de plazo, la falta de integración de los involucrados y deficiente gestión colaborativa; afectando de esta manera a la rentabilidad del negocio por la mala calidad constructiva. / This thesis, has the purpose of applying a collaborative work methodology for the management of urban empowerment projects of the Company La Fortaleza, through a simulation of the final product and that forms a database that allows managing the elements that form part of the infrastructure throughout the project life cycle. This methodology is BIM (Building Information Modeling) that allows us to improve the understanding and communication of the project through its 3D visualization, generating, automatically, all the necessary information for the management of work sharing it to all those involved in real time. Urban habilitation is the process of converting a rustic or eriazo land into urban, where the premises of a duly consolidated urban area must have domiciliary public services, tracks, sidewalks and road infrastructure, water networks, sewage and sewage systems and street lighting, how is the San Antonio de Pachacamac project, Stage 7 - Manchay. Object of the study of this thesis. The thesis shows how useful it is to use BIM in the management of an urban habilitation project during the design and construction processes, thus identifying interference in the design stage; comparing with the traditional methodology that in the construction stage identifies the interferences that cause the reprocesses, which quantified represent economic losses, extensions of term, the lack of integration of those involved and poor collaborative management; thus affecting the profitability of the business due to poor construction quality. / Trabajo de investigación

In today's architecture, engineering, and construction (AEC) industry, building information modeling (BIM) technologies and practices are making a significant difference in how building projects are delivered. BIM models and tools let stakeholders visualize, simulate, and analyze how a building might behave, perform, or appear - with more precision than ever before. BIM technology and practices are not only improving design and construction processes by delivering projects faster, more cost effectively, and more sustainably, but are also helping BIM professionals by expanding career possibilities within the field. This paper identifies key personnel in AEC industry who are taking advantage of BIM technologies and practices and explains how BIM has enhanced their career paths. The study found that new processes of BIM enhance the careers of existing professionals and create new career paths for young professionals. Until recently, positions like BIM engineer/BIM manager did not exist, but now they are key positions in many companies. BIM is also opening up positions for young engineers in nontraditional industries like manufacturing, energy, media and entertainment, healthcare companies, and facility management.

Estimating is a critical aspect of every construction project. The most tedious component of an estimate is the quantity takeoff. Different tools are available to improve an estimator's productivity for a quantity takeoff. Faster quantity takeoffs enable estimator to bid more jobs. This study analyzed the time and accuracy of performing quantity takeoffs when using building information modeling (BIM) through a comparison study using Revit (BIM software) and On-Center's OST. In preparation for the study the researcher conducted a pilot study. Participants of the study were asked to perform a quantity takeoff using both Revit and OST. Their resulting data was then, analyzed comparing both the time and accuracy of each item taken off. The subjects' perspectives on the two different methods of performing takeoff are also included in the findings of this study. This study focused on a conceptual estimate takeoff for a small commercial building. The results of the study showed that, on average, those using BIM were able to perform the overall takeoff faster than those using OST while still maintaining equivalent accuracy. This study includes methods to improve productivity for quantity takeoff through an analysis of the takeoffs of counts, areas, and lengths. Findings of this study include methods, techniques, and cautions for performing a quantity takeoff using BIM.

Building Information Modeling has provided many benefits to the architectural, engineering, construction and facilities management communities. Many studies have been done to validate the asserted benefits, including benefits to the field of estimating. The studies on estimating are currently limited to the realm of conceptual estimates, and have only treated detailed estimates in the abstract. The purpose of this study was to determine how BIM was being used by companies in a hard bid, or detailed estimate scenario. The research team used the Deseret Towers housing project at Brigham Young University as the basis for the research. A building information model (BIM) was provided to all bidders on the project, and at the conclusion of the bidding process a survey was used to determine how the contractors used the model in their bidding processes. The findings determined that a few of the contractors did use the model for quantity takeoff, and one actually used the quantities as the basis for the submitted bid. Additionally, the survey attempted to determine the prevailing attitudes of the estimators toward BIM as a tool in estimating, and their opinions of the future of BIM in estimating.

There has been an increase in adoption of building information modeling (BIM) by commercial contractors over the past few years but there is not a clear indication of current application or the frequency of each use. This research was undertaken to determine the frequency and best practices of using BIM in commercial construction. Leading commercial contracting firms were contacted and employees were selected to complete a telephone survey that was designed to determine how they are using BIM. It was found that BIM is being used with more frequency on projects, with plans to continue to implement it even further on all projects that allow for its use. Most companies are incorporating trade contractors in their coordination meetings but are taking the lead to ensure a high standard is maintained. Trade contractors are given responsibility to resolve smaller clashes while bringing the larger problems to the clash detection meetings. The model quality being received is increasing as well the frequency of models being received from the design team; however, there is a lack of consensus as to the level of development requirement to ensure the model can be used for facilities management. Commercial contractors are adopting building information modeling for a variety of reasons. These include client requirements, innovative technology strategies, and fear of being left behind. Overall its use improves processes within their companies. The general agreement is that BIM is having a positive impact on profitability, schedules and sales. BIM further improves the efficiency, effectiveness and competitiveness. The best practices undertaken by commercial contractors include using BIM as a sales and marketing tool, utilizing subcontractors knowledge and allowing them to resolve minor clashes, having combination of BIM teams and BIM experts and investing in training employees and further development of BIM uses.

This thesis researched the accuracy of measured energy data in comparison to estimated hand calculation data and estimated building energy performance simulation data. In the facility management industry, there is minimal evidence that building energy performance software is being used as a benchmark against measured energy usage within a building. Research was conducted to find examples of measured energy data compared to simulated data. The study examined the accuracy of a simulation software and hand calculations to measured energy data. Data suggests that comparisons may be made between building energy performance simulated data and measured data, though comparisons are solely based on each individual case. Data suggests that heating load simulation data is more accurate for benchmarks than cooling load simulation data. Importing models into Autodesk Green Building Studio (GBS) was not as successful as was expected. When only four of the initial ten building models chosen imported successfully, the remaining twenty-five other building models were imported. Only two of the twenty-five models successfully imported into GBS. The sample size of this research changed from ten to six. The results of this study show that GBS simulated data was close to actual data for the heating loads. For the cooling loads, however, GBS simulated data was consistently low in comparison to the actual data. The results of this study show that hand calculations were consistently low and not as close as GBS simulated data when compared to the actual data for the heating loads. The opposite was true with the cooling loads as hand calculations were consistently high in comparison to actual data.

Building Information Modeling (BIM) use in the contracting industry has grown significantly in recent years. With this change in the construction industry, consensus has not been reached as to what BIM is, who is using it and what they are using it for. The purpose of this research was to determine current BIM practices of US-based commercial MEP contractors. Executive, middle management, and field personnel were interviewed to determine the current BIM practices in their companies. The majority of companies interviewed were using BIM and most were using it on a significant portion of their projects. The majority of MEP contractors using BIM were seeing positive results in many of six key performance indicators, profitability, schedule duration, field efficiency, change orders, rework, and safety. The top uses of BIM for MEP contractors were clash detection coordination, prefabrication, design creation, and quantity take-off/cost estimating. Most MEP contractors have not yet incorporated BIM for scheduling, sequencing, or safety analysis. Additionally most MEP contractors did not have a formal BIM training program in their company.

Industri 4.0 bygger på en grundprocess som går ut på att  digitalisera information, koppla ihop information och enheter och därpå   automatisera processer. Inom fastighetsbranschen har denna process lett till uppkomst av ett nytt teknologiskt spår - BIM - Byggnadsinformationsmanagement (Building Information Management). Denna rapport undersöker och ger en djupare förklaring av BIM som verktyg, metod och tankesätt både teoretiskt genom en bakgrundsbeskrivning och praktiskt genom ett konkret exempel.Det konkreta exemplet undersöker hur man med hjälp av moderna branddetektorer med inbyggda temperaturmätare kan beskriva temperaturen i ett rum i realtid. Resultatet visar samband mellan temperatur uppmätt med en branddetektor i takhöjd och temperatur på arbetshöjd satt till 140cm från golvet. Resultatet sätts sedan i ett bredare användingsperspektiv som förslag på vidare undersökningsarbete. / Industry 4.0 is based on a basic process of digitizing information, linking information and devices, and automating processes. In the real estate industry, this process has led to the emergence of a new technology track - BIM - Building Information Management. This report investigates and gives a deeper explanation of BIM as a tool, method and mindset, both theoretically, by a background description and practical by a concrete example. The concrete example investigates how the temperature of a room can be described using modern fire detectors with built-in temperature gauge in real time. The result shows the correlation between temperature measured with a fire detector at ceiling height and temperature at work height set to 140cm from the floor. The result is then put in a broader perspective as a proposal for further investigation.
