Design And Construction

Abstract Traditionally, the design coordination process is carried out by overlaying and comparing 2D drawings made by different project participants. Detecting information errors from a composite drawing is especially challenging and error prone. This procedure usually leaves many design errors undetected until construction begins, and typically lead to rework. Correcting conflict issues, which were not identified during design and coordination phase, reduces the overall productivity for everyone involved in the construction process. The identification of construction issues in the field generate Request for Information (RFIs) that is one of delays causes. The application of Virtual Design and Construction (VDC) tools to the coordination processes can bring significant value to architecture, structure, and mechanical, electrical, and plumbing (MEP) designs in terms of a reduced number of errors undetected and requests for information. This paper is focused on evaluating requests for information (RFI) associated with water/sanitary facilities of a BIM model. Thus, it is expected to add improvements of water/sanitary facility designs, as well as to assist the virtual construction team to notice and identify design problems. This is an exploratory and descriptive research. A qualitative methodology is used. This study adopts RFI’s classification in six analyzed categories: correction, omission, validation of information, modification, divergence of information and verification. The results demonstrate VDC’s contribution improving the plumbing system designs. Recommendations are suggested to identify and avoid these RFI types in plumbing system design process or during virtual construction.

Real-time collaboration of multiple digital models is vital for successful construction projects using Virtual Design and Construction (VDC) or Building Information Modeling (BIM). Real-time collaboration allows users to workshare within a multidisciplinary team to co-author multiple smart digital models for better efficiency. This can be done in two ways, either using a physical server (Local Area Network/LAN server) or cloud-based server (Wide Area Network/WAN server). Such cloud-based servers are A360, C4R, Collaboration for Revit, or BIM360Design collaborate, etc. However, above-mentioned cloud services come at a significant price, making it challenging for academia and small businesses to perform real-time collaboration using BIM/VDC models. To find an affordable alternative, an attempt was made as part of the Virtual Design and Construction (VDC) course offered by the Construction Science and Management Department (CSM). For this case study, a popular and free (Google) cloud server was tested as a WAN server to host four multidisciplinary collaborative VDC central models for five users across five different geographic locations and time zones. The study rendered successful results to establish a real-time collaborative workshare environment; hence, can significantly benefit academia and small business.

<p class="Resumo">A implementação de tecnologias da informação na construção civil, como <em>Virtual Design and Construction</em> / <em>Building Information Modeling</em> (VDC/BIM) representam uma nova perspectiva para melhores práticas na AECO (Arquitetura; Engenharia; Construção; Operação). Contudo, no cenário brasileiro, estas práticas carecem de métodos para medição e análise de desempenho processual da informação na gestão do processo de projeto, demonstrando a deficiência da documentação de critérios e seleção de indicadores que contribuam para melhoria do setor da construção civil. Trata-se de uma pesquisa descritiva sobre a exploração do método <em>VDC Scorecard</em> e a adaptação à realidade brasileira, tendo por base pesquisa bibliográfica e documental existentes em bases de dados internacionais e nacionais explorando os seguintes aspectos: benefícios registrados; dificuldades na implementação; boas práticas na gestão do projeto. A pesquisa valida a importância dos métodos de desempenho que se adequem ao contexto nacional, viabilizando a integração e controle da informação entre agentes envolvidos num modelo colaborativo de edificação virtual e apropriação de dados por meio dos modelos de desempenho configurados através da análise contínua dos processos, da organização e do produto. Esta apropriação possibilita a documentação de um banco de dados de práticas eficientes para gestão de processos de projeto configurando o desempenho do modelo.</p>

The nature and growth of magmatic plumbing systems are of fundamental importance to igneous geology. Traditionally, magma chambers have been viewed as rapidly emplaced bodies of molten rock or partially crystallized “magma mush” connected to the surface by a narrow cylindrical conduit (referred to as the “balloon-and-straw” model). Recent data suggest, however, that magma chambers beneath volcanoes are formed incrementally through amalgamation of smaller intrusions. Here we present the first high-resolution three-dimensional reconstruction of an ancient volcanic plumbing system as a large laccolithic complex. By integrating seismic reflection and gravity data, we show that the ~200 km3 laccolith appears to have formed through partial amalgamation of smaller intrusions. The complex appears to have fed both surface volcanism and an extensive sill network beneath the volcanic edifice. Numerous sills are imaged within the volcanic conduit, indicating that magma stalled at various levels during its ascent. Our results reveal for the first time the entire multicomponent plumbing system within a large ancient shield volcano.

Traditional Setting

Successful management of the building design coordination process is critical to the efficient delivery of cost-effective and quality projects. The traditional setting of design coordination, however, is inefficient and error-prone. Building information modelling (BIM) has proven valuable for increasing satisfaction with the meeting process and decreasing arguments over issues. Despite the many advantages of BIM tools, however, many design coordination issues remain undetected, design issues are poorly documented, and coordination strategies are inefficient. The objective of this study was to develop a characterization of the BIM building design coordination process, identify the bottlenecks in the current process, and provide design considerations to alleviate the bottlenecks. The bottlenecks include: outdated BIM, disconnected trades, lack of terminology, insufficient documentation, inefficient transitions across views and artifacts, unavailability of design information, information discrepancy, unfit navigation tools, and office–site disconnect. The outcomes of this research is useful for future construction projects and the software development community.

Magmatic Plumbing System

Abstract. Understanding the anatomy of magma plumbing systems of active volcanoes is essential not only for unraveling magma dynamics and eruptive behaviors, but also to define the geometry, depth and temperature of the heat sources for geothermal exploration. The Pleistocene-Holocene Los Humeros volcanic complex is part of the Eastern Trans-Mexican Volcanic Belt (Central Mexico) and it represents one of the most important exploited geothermal fields in Mexico with ca. 90 MW of produced electricity. A field-based petrologic and thermobarometric study of lavas erupted during the Holocene (post-Caldera stage) has been performed with the aim to decipher the anatomy of the magmatic plumbing system existing beneath the caldera. New petrographical, whole rock major element data and mineral chemistry were integrated within a suite of inverse thermobarometric models. Compared with previous studies where a single voluminous melt-controlled magma chamber (or "Standard Model") at shallow depths was proposed, our results support a more complex and realistic scenario characterized by a heterogeneous multilayered system comprising a deep (ca. 30 km) basaltic reservoir feeding progressively shallower and smaller distinct stagnation layers, pockets and batches up to very shallow conditions (1 kbar, ca. 3 km). Evolution of melts in the feeding system is mainly controlled by differentiation processes via fractional crystallization, as recorded by polybaric crystallization of clinopyroxenes and orthopyroxenes. Moreover, this study attempts to emphasize the importance to integrate field-petrography, texture observations and mineral chemistry of primary minerals to unravel the pre-eruptive dynamics and therefore the anatomy of the plumbing system beneath an active volcanic complex, which notwithstanding the numerous existing works is still far to be well understood. A better knowledge of the heat source feeding geothermal systems is very important to improve geothermal exploration strategies.
