A gestão do processo de projeto em empresas incorporadoras e construtoras.

Nos últimos anos, a discussão sobre a implementação do conceito de modelagem da informação da construção tem permanecido nas pautas das empresas do setor da construção civil em todo o mundo; no entanto, no cenário brasileiro, o descompasso entre a estratégia setorial e as iniciativas individuais de algumas empresas tem chamado a atenção. Partindo do princípio de que o conceito de modelagem da informação da construção, em função do seu caráter de inovação tecnológica, carrega consigo a necessidade de mudanças, a reflexão e adaptações sobre os diversos processos que permeiam a produção dos empreendimentos de construção torna-se fundamental. Nesse contexto, o objetivo desta tese é propor um conjunto de Diretrizes para Gestão do Processo de Projeto em Empresas Incorporadoras e Construtoras. As Diretrizes estão pautadas na necessidade de definir o projeto como um processo estratégico, inserindo a sua gestão como elemento fundamental para a facilitação e integração do fluxo de informações no âmbito do empreendimento. Para a concretização do objetivo da tese, realizaram-se Estudos de Caso em empresas Incorporadoras e Construtoras brasileiras com o objetivo de diagnosticar as práticas vigentes de gestão do processo de projeto. Em paralelo, conduziu-se a reflexão sobre as responsabilidades do gestor do processo de projeto no âmbito da modelagem por meio de Grupos de Foco envolvendo gestores do processo de projeto e especialistas em tecnologia da informação aplicada à construção. Além disso, a metodologia de pesquisa contempla um Estudo de Caso com foco para a implementação do Conceito de Modelagem da Informação no contexto setorial do Reino Unido. Como resultado das Diretrizes, apresenta-se o Modelo para Gestão do Processo de Projeto no Contexto da Modelagem, seguido pelo Plano de Reestruração para o Departamento de Projetos, o qual visa à proposição de um modelo estruturado para condução das mudanças necessárias nas áreas responsáveis pelo processo de projeto das empresas Incorporadoras e Construtoras.

Implementation Feasibility of a Digital Nervous System for the Construction Industry: For Efficient and Effective Information Management across the Project Lifecycle

The construction industry has long been considered as highly fragmented and non-collaborative industry. This fragmentation sprouted from complex and unstructured traditional coordination processes and information exchanges amongst all parties involved in a construction project. This nature coupled with risk and uncertainty has pushed clients and their supply chain to search for new ways of improving their business process to deliver better quality and high performing product. This research will closely investigate the need to implement a Digital Nervous System (DNS), analogous to a biological nervous system, on the flow and management of digital information across the project lifecycle. This will be through direct examination of the key processes and information produced in a construction project and how a DNS can provide a well-integrated flow of digital information throughout the project lifecycle. This research will also investigate how a DNS can create a tight digital feedback loop that enables the organisation to sense, react and adapt to changing project conditions. A Digital Nervous System is a digital infrastructure that provides a well-integrated flow of digital information to the right part of the organisation at the right time. It provides the organisation with the relevant and up-to-date information it needs, for critical project issues, to aid in near real-time decision-making. Previous literature review and survey questionnaires were used in this research to collect and analyse data about information management problems of the industry – e.g. disruption and discontinuity of digital information flow due to interoperability issues, disintegration/fragmentation of the adopted digital solutions and paper-based transactions. Results analysis revealed efficient and effective information management requires the creation and implementation of a DNS.

Comparing Common Data Environment Platforms for Student Collaborative Working: A Case Study from Ulster University

PAS1192-2 (2013) outlines the “fundamental principles of Level 2 information modeling”, one of these principles is the use of what is commonly referred to as a Common Data Environment (CDE). A CDE could be described as an internet-enabled cloudhosting platform, accessible to all construction team members to access shared project information. For the construction sector to achieve increased productivity goals, the next generation of industry professionals will need to be educated in a way that provides them with an appreciation of Building Information Modelling (BIM) working methods, at all levels, including an understanding of how data in a CDE should be structured, managed, shared and published. This presents a challenge for educational institutions in terms of providing a CDE that addresses the requirements set out in PAS1192-2, and mirrors organisational and professional working practices without causing confusion due to over complexity. This paper presents the findings of a two-year study undertaken at Ulster University comparing the use of a leading industry CDE platform with one derived from the in-house Virtual Learning Environment (VLE), for the delivery of a student BIM project. The research methodology employed was a qualitative case study analysis, focusing on observations from the academics involved and feedback from students. The results of the study show advantages for both CDE platforms depending on the learning outcomes required.

Quantifying the impacts of urban wind sheltering on the building energy consumption

Common building energy modeling approaches do not account for the influence of surrounding neighborhood on the energy consumption patterns. This thesis develops a framework to quantify the neighborhood impact on a building energy consumption based on the local wind flow. The airflow in the neighborhood is predicted using Computational Fluid Dynamics (CFD) in eight principal wind directions. The developed framework in this study benefits from wind multipliers to adjust the wind velocity encountering the target building. The input weather data transfers the adjusted wind velocities to the building energy model. In a case study, the CFD method is validated by comparing with on-site temperature measurements, and the building energy model is calibrated using utilities data. A comparison between using the adjusted and original weather data shows that the building energy consumption and air system heat gain decreased by 5% and 37%, respectively, while the cooling gain increased by 4% annually.

From point cloud to HBIM: an integrated workflow for 3D reconstruction of heritage building with model accuracy evaluation

Modern society is now facing significant difficulties in attempting to preserve its architectural heritage. Numerous challenges arise consequently when it comes to documentation, preservation and restoration. Fortunately, new perspectives on architectural heritage are emerging owing to the rapid development of digitalization. Therefore, this presents new challenges for architects, restorers and specialists. Additionally, this has changed the way they approach the study of existing heritage, changing from conventional 2D drawings in response to the increasing requirement for 3D representations. Recently, Building Information Modelling for historic buildings (HBIM) has escalated as an emerging trend to interconnect geometrical and informational data. Currently, the latest 3D geomatics techniques based on 3D laser scanners with enhanced photogrammetry along with the continuous improvement in the BIM industry allow for an enhanced 3D digital reconstruction of historical and existing buildings. This research study aimed to develop an integrated workflow for the 3D digital reconstruction of heritage buildings starting from a point cloud. The Pieve of San Michele in Acerboli’s Church in Santarcangelo Di Romagna (6th century) served as the test bed. The point cloud was utilized as an essential referential to model the BIM geometry using Autodesk Revit® 2022. To validate the accuracy of the model, Deviation Analysis Method was employed using CloudCompare software to determine the degree of deviation between the HBIM model and the point cloud. The acquired findings showed a very promising outcome in the average distance between the HBIM model and the point cloud. The conducted approach in this study demonstrated the viability of producing a precise BIM geometry from point clouds.

HBIM to Virtual Reality Workflow for Industrial Archaeology Immovable Assets’ Management: A Case Study

As a witness on the industrialization in Bologna, since its first generation was born in the late 1760, the Battiferro lock has been coping with the innovation that the city experienced throughout the centuries, until it has lost its functionality due to the technological development for which Bologna’s canals were gradually covered starting from the 1950s under Giuseppe Dozza ’s administration, as part of the reconstruction, reclamation and urban requalification that was carried out in the aftermath the World War II and which involved the whole city. The interest of the research carried out on this case study was primarily to reintroduce the landmark that is still intact, to what is considered to be the fourth generation of the industrial revolution, namely in the construction field, which is recognized as Construction 4.0, by means of the Historic (or Heritage) Information Modeling HBIM and Virtual Reality (VR) application. A scan-to-BIM approach was followed to create 3D as-built BIM model, as a first step towards the storytelling of the abandoned industrial built asset in VR environment, or as a seed for future applications such as Digital Twins (DT), heritage digital learning, sustainable impact studies, and/or interface with other interfaces such as GIS. Based on the HBIM product, examples of the primary BIM deliverables such as 2D layouts is given, then a workflow to VR is proposed and investigated the reliability of data and the type of users that may benefit of the VR experience, then the potential future development of the model is investigated, with comparison of a relatively similar experience in the UK.

Construção do edifício Báltico Center, Parque das Nações

É uma inevitabilidade que, mesmo num curso de engenharia, a vertente académica seja preponderante sobre a vertente académica. A evolução dos materiais, das tecnologias e da própria construção a isso obrigam. No entanto, para se poder perceber os impactes dessa evolução, torna-se necessário ver in loco a sua aplicação. Assim, após seis anos de curso, um estágio numa empresa de construção foi o passo que me pareceu mais lógico e enriquecedor. O facto de ser em obra propôs-me um desafio extra por ser uma actividade com uma dinâmica totalmente diferente da que estava habituado. As 16 semanas de estágio foram essenciais para adquirir experiência e alguns conhecimentos extremamente úteis na futura vida profissional. Pretende-se, com este relatório, resumir de uma forma simples mas completa, essa experiência, descrevendo, ao longo de quatro capítulos, o projecto, as soluções técnicas propostas para resolver alguns problemas encontrados, a vivência de trabalhar numa obra e a sua organização; e, por último, uma solução de planeamento e gestão da obra inovadora em Portugal: o Building Information Modelling (B.I.M.).
