The Swedish Government has set a goal to reach net zero emissions of greenhouse gases by 2045, which together with the commissioning to the Swedish Housing Agency to prepare requirements for a climate declaration that shall reduce the climate impact from buildings, has enforce the AEC industry to provide solutions that help reach these targets. The introduction of the integration of BIM technologies, together with the LCA methodology has been suggested as a key solution to solve this problem. To achieve the results for this study, two main objectives were stablished. The first objective was to develop a BIM model in SMC able to produce automated climate calculations. The second objective was to perform interviews with relevant actors about this tool. The integration of those objectives helped to answer the research questions of this study. This study provides a way of performing automated climate calculations for construction projects using classification of materials in SMC and calculations in Excel. It also has the ability to perform data visualization of the carbon footprints of the complements in the 3D models of the project using the GWP of the chosen materials. It can be said that it is a great tool to introduce to decision-makers an easy way to identify the hotspots of carbon emissions and choose more sustainable alternatives. / Den Svenska Regeringen har fastställt ett mål att nå utsläppen av växthusgaser netto noll till 2045, som tillsammans med uppdraget till Boverket att förbereda krav på en klimatdeklaration som ska minska klimatpåverkan från byggnader har tvingat AEC-industrin att tillhandahålla lösningar som hjälper till att nå dessa mål. Införandet av integrationen av BIM-teknologier tillsammans med LCA-metoden har föreslagits som en nyckellösning för att lösa detta problem. För att uppnå resultaten för denna studie fastställdes två huvudmål. Det första målet var att utveckla en BIM-modell i SMC som kunde producera automatiserade klimatberäkningar. Det andra målet var att genomföra intervjuer med relevanta aktörer om detta verktyg. Integrationen av dessa mål hjälpte till att besvara forskningsfrågorna i denna studie. Denna studie ger ett sätt att utföra automatiserade klimatberäkningar för byggprojekt med klassificering av material i SMC och beräkningar i Excel. Det har också förmågan att utföra datavisualisering av kolavtryck av komplementen i projektets 3D-modeller med GWP för de valda materialen. Det kan sägas att det är ett bra verktyg att introducera för beslutsfattare ett enkelt sätt att identifiera de hotspots som koldioxidutsläpp och välja mer hållbara alternativ.

Life Cycle Assessments on buildings and various environmental certificates are starting to become customary for newbuilding projects in Sweden. Building materials play a big part in a building’s environmental impact. Earlier research indicates that Life Cycle Assessments is not a routine in today’s construction process and it may depend on uncertainties in the methods of quantifying carbon dioxide emissions. This master thesis focuses on how equivalent carbon dioxides, a standard unit to quantify greenhouse gas emissions, of building materials can be integrated with Building Information Modelling. Through meetings with experts in the field, data has been collected. A 3D model of a house was built in order to evaluate both an integration with a cost calculation tool and directly with the 3D model. The results showed how the cost calculation tool works for calculations of equivalent carbon dioxides, early in the pre-construction phase. Difficulties in finding corresponding materials in their database were found and issues with summarizing carbon dioxide data. The integration directly into the 3D model, with visual programming, proved an insert for each materials’ carbon dioxide emissions worked. This allows further updates throughout the building process. It was also possible to import material information to a carbon dioxide calculation tool. This evaluation opened up a possibility to change and update carbon dioxide emissions at an early design stage of a building process with Building Information Modelling along with a need of organizational change due to today's traditional building processes. / Livscykelanalyser på byggnader och olika typer av miljöbyggnads-certifieringar blir allt vanligare för nya byggprojekt i Sverige. Materialet i en byggnad spelar en stor roll av hela byggnadens miljöpåverkan. Tidigare forskning indikerar att livscykelanalyser inte är en rutin i dagens byggprocesser vilket kan bero på att osäkerheter i de olika metoderna bakom koldioxidberäkningar. Den här artikeln fokuserar på hur koldioxidekvivalenter av byggnadsmaterial kan bli integrerade med Byggnadsinformationsmodellering. Genom möten med experter i området har datainsamling gjorts för det ändamålet. För att undersöka integreringen byggdes en 3D-modell upp och som senare användes för beräkningar av koldioxidutsläpp i ett kostnads-kalkyleringsverktyg samt undersöka hur en införing av koldioxidekvivalenter direkt i 3D-modellen kunde göras. Resultaten visade hur kostnads-beräkningsverktyget fungerar för beräkningar av koldioxidekvivalenter, tidigt i byggprocessen. Svårigheter i att hitta motsvarande material i kalkyleringsverktygets databas upptäcktes under utvärderingen samt en sammanfattande rapport för beräkningarna. Integrationen direkt i 3D-modellen med visuell programmering visade att en inmatning av koldioxidutsläpp för varje material fungerade vilket möjliggör uppdateringar under hela byggprocessen. Det var också möjligt att importera materialinformation till ett koldioxidberäkningsverktyg. Det öppnar upp möjligheter att ändra och uppdatera koldioxidutsläpp för material tidigt i byggprocessen med hjälp av Byggnadsinformationsmodellering och visar behov av organisationsförändringar på grund av dagens traditionella byggprocess.

[ES] El mayor desafío en la gestión del uso público del patrimonio es establecer una relación sostenible entre patrimonio y turismo, ya que el acceso público, si bien promueve el interés social por su conservación, también representa un riesgo para la preservación de los recursos.

The information generated by the multidisciplinary teams involved in public use management is generally incomplete, uncoordinated and out of date. The lack of a reliable source of information generates low levels of efficiency in such management, which consequently jeopardises the ability to protect the resources against the impact of visitors and reduces social interest in their conservation. Heritage Building Information Modelling (HBIM) is a collaborative work system in which the stakeholders involved share geometric, semantic and documentary information about the heritage asset in a coordinated way. It offers an opportunity to improve the efficiency of the management of the public use of heritage. Bearing in mind the expected growth in the use of HBIM in Spain in the near future, the aim of this research is to develop, for the first time, an HBIM protocol that will help professionals to implement HBIM so as to achieve more efficient planning and management of the public use of heritage in the four areas involved in it, that is, preventative conservation, visitor flow management, heritage interpretation and heritage dissemination. The research method used for this purpose is Design Science Research (hereinafter, DSR). Thus, the study began with a comprehensive review of the literature on the use of HBIM for the management of the public use of heritage, which revealed the knowledge gap that exists in this area. To analyse the current management of the public use of heritage, three case studies were taken and data were collected using the semi-structured interview technique and direct observation of public visitation. The planning of the four areas of public use was analysed based on the data obtained through the semi-structured interviews and the analysis of specific technical documentation. The results of these analyses revealed problems of inefficiency in the current public use planning and management. In order to provide a solution to this problem, an HBIM Protocol was developed that enables public use to be planned and managed more efficiently. Two aspects of the HBIM Protocol, visitor management and heritage interpretation, were successfully implemented in the case study of the San Juan del Hospital ensemble in Valencia. Lastly, the applicability and usefulness of the protocol were evaluated with the collaboration of a panel of experts in the cultural management of the case study, in each area of public use and in BIM. The results from implementing the HBIM Protocol to the case study of the San Juan del Hospital complex in Valencia show for the first time that HBIM and, in particular, the Revit software package can be a useful tool for a more efficient analysis, planning and management of public visitation to heritage assets. This study shows that the capacity of HBIM to unify the information generated by the different stakeholders involved in the conservation of heritage facilitates the decision-making required to design the tourist itinerary, to manage the visitor flows and to determine the recreational carrying capacity in a more comprehensive manner. These results have made it possible to identify future lines of research focused on achieving visitor flow management in real time by linking sensors or GPS devices to HBIM models, while also seeking to refine the HBIM Protocol by applying it to larger case studies. / Salvador García, E.

<p dir="ltr">Weather conditions such as thunderstorms, wind shear, snowstorms, turbulence, icing, and fog can create potentially hazardous flying conditions in the National Airspace System (NAS) (FAA, 2021). In general aviation (GA), hazardous weather conditions are most likely to cause accidents with fatalities (FAA, 2013). Therefore, it is critical to communicate weather conditions to pilots and controllers to increase awareness of such conditions, help pilots avoid weather hazards, and improve aviation safety (NTSB, 2017b). Pilot Reports (PIREPs) are one way to communicate pertinent weather conditions encountered by pilots (FAA, 2017a). However, in a hazardous weather situation, communication adds to pilot workload and GA pilots may need to aviate and navigate to another area before feeling safe enough to communicate the weather conditions. The delay in communication may result in PIREPs that are both inaccurate and untimely, potentially misleading other pilots in the area with incorrect weather information (NTSB, 2017a). Therefore, it is crucial to enhance the PIREP submission process to improve the accuracy, timeliness, and usefulness of PIREPs, while simultaneously reducing the need for hands-on communication.</p><p dir="ltr">In this study, a potential method to incrementally improve the performance of an automated spoken-to-coded-PIREP system is explored. This research aims at improving the information extraction model within the spoken-to-coded-PIREP system by using underlying structures and patterns in the pilot spoken phrases. The first part of this research is focused on exploring the structural elements, patterns, and sub-level variability in the Location, Turbulence, and Icing pilot phrases. The second part of the research is focused on developing and demonstrating a structured two-level Named Entity Recognition (NER) model that utilizes the underlying structures within pilot phrases. A structured two-level NER model is designed, developed, tested, and compared with the initial single level NER model in the spoken-to-coded-PIREP system. The model follows a structured approach to extract information at two levels within three PIREP information categories – Location, Turbulence, and Icing. The two-level NER model is trained and tested using a total of 126 PIREPs containing Turbulence and Icing weather conditions. The performance of the structured two-level NER model is compared to the performance of a comparable single level initial NER model using three metrics – precision, recall, and F1-Score. The overall F1-Score of the initial single level NER model was in the range of 68% – 77%, while the two-level NER model was able to achieve an overall F1-Score in the range of 89% – 92%. The two-level NER model was successful in recognizing and labelling specific phrases into broader entity labels such as Location, Turbulence, and Icing, and then processing those phrases to segregate their structural elements such as Distance, Location Name, Turbulence Intensity, and Icing Type. With improvements to the information extraction model, the performance of the overall spoken-to-coded-PIREP system may be increased and the system may be better equipped to handle the variations in pilot phrases and weather situations. Automating the PIREP submission process may reduce the pilot’s hands-on task-requirement in submitting a PIREP during hazardous weather situations, potentially increase the quality and quantity of PIREPs, and share accurate weather-related information in a timely manner, ultimately making GA flying safter.</p>

<p dir="ltr">Building Information Modeling (BIM) supports engineering and performance analysis for buildings and civil infrastructure from the initial design stage. BIM offers engineers access to building and infrastructure objects, along with their associated data, which can be utilized across various platforms to develop analytical models. However, the interoperability between BIM and analytical models is still limited and challenging. One such limitation and challenge is in the interoperability between BIM and Building Energy Modeling (BEM). Despite the fact that interoperability of geometry and material information between BIM and BEM has been extensively investigated, the interoperability of heating, ventilation, and air conditioning (HVAC) information, which is a crucial part in BEM, was underinvestigated. Another limitation is that the shared objects frequently lose their identification across different models during the processes of their creation, design iterations, and model transformation. In addition, current building and civil infrastructure projects mainly rely on Portable Document Format (PDF) plans as the official deliverables and documents to be stored, communicated, and transferred among different stakeholders. The transition from 2D PDF plans to 3D BIM remains challenging because manually creating a BIM instance model from 2D drawings can be laborious, time-intensive, and susceptible to errors.</p><p dir="ltr">To address these gaps, this dissertational research introduces new Industry Foundation Classes (IFC)-based algorithmic methods that utilize the state-of-the-art Data-driven Reverse Engineering Algorithm Development (D-READ) method and the invariant signatures of architecture, engineering, and construction (AEC) objects to (1) develop algorithms that can extract the information from 2D PDF drawings and reconstruct the 3D semantically segmented and enriched BIM instance models, (2) develop object mapping algorithms for interfacing BIM and analytical models (e.g., BEM, structural analysis models, etc.) by automatically mapping building objects, and (3) iteratively develop the HVAC information transformation algorithm between BIM and BEM. Following the proposed methods, algorithms were developed to (1) semi-automate the creation of semantically segmented and enriched 3D IFC-based bridge BIM instance models using 2D PDF bridge plans, (2) map space objects between BIM instance models and BEM (OpenStudio model) based on their invariant signatures, and (3) transform HVAC objects from IFC-based BIM instance models to BEM with all the necessary information for energy simulation, using (1) PDF drawings for 12 bridges located in various parts of Indiana, (2) a 2-story duplex apartment building, and (3) a 2-story office building model and a 2-story residential building model, respectively.</p><p dir="ltr">The developed algorithms were tested on three cases: (1) the PDF information extraction algorithm was tested on six bridges, which achieved 97.7% precision and 94.4% recall. In addition, it decreased the time required to create bridge BIM instance models by 94.9% compared to the manual approach; (2) the object mapping algorithm was evaluated using a 4-story office building model containing 82 spaces. The results demonstrated that the algorithm attained 90% precision and 90% recall in mapping space objects. Additionally, a 4.88% improvement in the accuracy of energy simulation results was observed when compared to simulations without space mapping; (3) the HVAC transformation algorithm was tested on two models with distinct HVAC systems: a 4-story office building model featuring a boiler radiator system and a 2-story clinic building featuring a VAV system. The algorithm achieved transformation accuracies of 97.5% and 98.7%, respectively, compared to manually created evaluation models in OpenStudio. Additionally, the algorithm-generated models demonstrated satisfactory performance with regard to precision, with less than 9.6% error in total annual energy consumption compared to the evaluation models.</p><p dir="ltr">This dissertational research introduces a new IFC-based approach to fill the forementioned research gaps in BIM interoperability for buildings and civil infrastructures. It facilitates improved accessibility compared to a proprietary workflow and will contribute to filling informational gaps (1) between 3D BIM and 2D PDF drawings, and (2) between BIM and analytical models. It builds a solid foundation for achieving (1) automated BIM reconstruction using 2D plans, and (2) smooth, accurate, and fully-automated HVAC objects transformation between BIM and BEM, for complete BIM-BEM interoperability. The proposed approach can also be leveraged to further expand BIM interoperability support by providing a novel data-driven approach for building and civil infrastructure projects.</p>

Sustainable performance of buildings has become a major concern among construction industry professionals. However, sustainability considerations are often treated as an add-on to building design, following ad hoc processes for their implementation. As a result, the most common problem to achieve a sustainable building outcome is the absence of the right information at the right time to make critical decisions. For design team members to appreciate the requirements of multidisciplinary collaboration, there is a need for transparency and a shared understanding of the process. The aim of this study is to investigate, model, and facilitate the early stages of Building Information Modelling (BIM) enabled Sustainable Building Design (SBD) by formalising the ad hoc working relationships of the best practices in order to standardise the optimal collaboration workflows. Thus, this research strives to improve BIM maturity level for SBD, assisting in the transition from ad hoc to defined , and then, to managed . For this purpose, this study has adopted an abductive research approach (iterative process of induction and deduction) for theory building and testing. Four (4) stages of data collection have been conducted, which have resulted in a total of 32 semi-structured interviews with industry experts from 17 organisations. Fourteen (14) best practice case studies have been identified, and 20 incidents narratives have been collected applying the Critical Decision Method (CMD) to examine roles and responsibilities, resources, information exchanges, interdependencies, timing and sequence of events, and critical decisions. As a result, the research has classified the critical components of SBD into a framework utilising content and thematic analyses. These have included the definition of roles and competencies that are essential for SBD along with the existing opportunities, challenges, and limitations. Then, Schedules of Services for SBD have been developed for the following stages of the RIBA Plan of Work 2013: stage 0 (Strategic Definition), stage 1 (Preparation and Brief), and stage 2 (Concept Design). The abovementioned SBD components have been coordinated explicitly into a systematic process, which follows Concurrent Engineering (CE) principles utilising Integrated DEFinition (IDEF) structured diagramming techniques (IDEF0 and IDEF3). The results have identified the key players roles and responsibilities, tasks (BIM Uses), BIM-based deliverables, and critical decision points for SBD. Furthermore, Green BIM Box (GBB) workflow management prototype tool has been developed to analyse communication and delivery of BIM-enabled SBD in a centralised system (Common Data Environment, CDE). GBB s system architecture for SBD process automation is demonstrated through Use Case Scenarios utilising the OMG UML (Object Management Group s Unified Modelling Language) notation. The proposed solution facilitates the implementation of BIM, Information Communication Technology (ICT), and Building Performance Analysis (BPA) software to realise the benefits of combining distributed teams expertise holistically into a common process. Finally, the research outcomes have been validated through academic and industrial reviews that have led to the refinement of the IDEF process model and framework. It has been found that collaborative patterns are repeatable for a variety of different non-domestic building types such as education, healthcare, and offices. Therefore, the research findings support the idea that a detailed process, which follows specified communication patterns, can assist in achieving sustainability targets efficiently in terms of time, cost, and effort.

<p>The construction industry contributes significantly to the GDP of the United States, attributing to its growth at an unprecedented rate. Efficient planning on all stages of construction is the only way to combat dynamic obstructions and deliver projects on time. The first element involved in the planning phase deals with the layout of the Construction Site. It significantly regulates the pace at which construction operations function and directly affects the time, cost, and safety linked to the successful delivery of the target project. Hence, it is paramount to ensure that every component of the construction site maneuvers with the utmost productivity. One such equipment that occupies significant attention while carrying out the CSLP process is Tower Crane. Tower crane optimization is pivotal to ensure proper lifting and handling of materials, and warrant conflict-free work zones. This research, therefore, aims to optimize its position by maximizing the lift ability. To achieve the goals, Generative Design- a paradigm that integrates the constructive features of mathematical and visual optimization techniques, is used to develop a relatively comprehensible prototype. The first part of the research, thus, utilized Generative Design on two construction sites- one from the United States and one from India. After implementing the visual programming algorithm, an improvement of 40% was warranted in the lift score. A pool of potential alternatives was explored and supplemented by the trade-off illustrations. The concept of trade-off was substantiated by allowing a framework for prioritization of lift cycles, and facilitating a holistic decision-making process. To evaluate the usability, 12 participants were chosen based on their previous experience with tower crane operations. The participants witnessed a live demonstration of the algorithm, answered a Likert scale questionnaire, and appeared for an open-ended interview to provide feedback about the proposed Generative Design technique. After carrying out narrative analysis for the usability aspect- it has been unanimously observed that the technique has extreme efficiency of usage and can evidently prevent the occurrence of errors. The study concludes by providing recommendations to augment the significance and usability of Generative Design for tower crane position optimization. </p><br>
