Application of Building Information Modeling (BIM) in the Planning and Construction of a Building

This paper aims to introduce Building Information Modeling (BIM) technology into the process of construction to achieve more efficient buildings, considering sustainability, economic improvements, reduced waste, and time optimization. The study involves the design, 3D modeling, planning, and monitoring of the work to assess the advantages and limitations of BIM through a real simulation. The methodology comprises theoretical foundations, 3D modeling, budgeting, and work monitoring. The project commenced with a 2D blueprint using Autodesk AutoCAD, followed by 3D modeling in Autodesk Revit. The resultant building, serving as an information system with a database and 3D modeling, allows for automated budgeting. The advantages of BIM encompass an interface between project and program, an interface between software, realistic renderings, precise material specifications, and family modeling. Limitations include the absence of material families, reformatting of Autodesk Revit tables when transferred to the Microsoft Excel program, generic family models with distorted renderings of reality, and heavy files. Despite these limitations, the implementation of BIM in buildings proves beneficial for projects. Collaborative work among stakeholders, optimization of project stages, and the reduction of expenses and rework can be achieved.

Service Life Design of Reinforced Concrete Maritime Infrastructure: Holistic Approach with Experiences from Chilean Cases

The consideration of the useful life of reinforced concrete in the different stages of a structure's life cycle, as a distinguishing factor in the design process for performance under aggressive environmental conditions, has presented new challenges in construction. This includes the development of new regulations incorporating innovative engineering materials, performance tests and modeling processes to estimate concrete deterioration over time, and construction processes ensuring adequate Quality Control and Quality Assurance (QAQC). As a result, infrastructure projects have been able to exceed their intended lifespan, maintaining serviceability levels for more than 100 years. One such example is the Chacao Bridge project currently under construction in southern Chile. This paper provides an overview of project stages from a holistic approach, focusing on aspects inherent to planning including design and construction processes, control stages for monitoring deterioration levels through regular diagnostics and appropriate monitoring to support ongoing structural health management. Additionally, it presents real case design examples carried out with specific models created for each case.

Managing coopetitive innovation: sharing while protecting knowledge in separated project teams

Existing research on coopetition acknowledges the dilemma companies face regarding sharing and protecting knowledge when developing coopetitive product innovation. To manage this dilemma, coopetitors can rely on two different organizational designs: the coopetitive project team (CPT) or the separated project team (SPT). The CPT fosters high knowledge sharing but creates uncertainty about knowledge protection. In contrast, the SPT limits the knowledge sharing but offers higher knowledge protection. While the CPT design has been studied in‐depth, the SPT design remains an underexplored black box. We know little about how knowledge is shared and protected within the SPT. To fill this gap, we conducted an ethnographic case study of a joint innovation project using SPT in the Chinese electric car industry. Our research shows how the SPT design manages the necessary knowledge sharing while protecting the knowledge. The project managers facilitate knowledge sharing by acting as the interface coordinator with the coopetitor, and the knowledge protection is guaranteed by a strict separation between the two coopetitors' operators. In SPT, the nature and the management of knowledge flows are not rigid but evolve according to the project stage.

Success of the tender stage of Ghanaian public labor-based construction projects

PurposeThe procurement reforms carried out by the Government of Ghana have led to the creation of the Public Procurement Authority and the passage of the Public Procurement (Amended) Act 2016. Nevertheless, many obstacles could prevent an open and fair competition during the procurement of works. This significantly affects the success of Ghanaian construction projects. Therefore, this paper aims to explore the factors to enhance the success of the contractor selection phase of the Ghanaian public labor-based construction project.Design/methodology/approachA quantitative research approach was adopted by this study. Data was collected through a self-administered questionnaire to 377 respondents across Ghana. The data was then analyzed using structural equation modeling.FindingsThis study revealed that external, project procedures and project management factors impact the Ghanaian labor-based contractor selection phase success.Research limitations/implicationsThis study is limited to the contractor selection phase of Ghanaian public labor-based projects and developing nations with similar socioeconomic characteristics.Social implicationsStrict adherence to this study’s findings will enable the government to undertake more infrastructure projects to raise the standard of living for its populace.Originality/valueAlthough several studies have been conducted to improve the success of construction projects in developing nations, very little focus has been placed on the success factors of the contractor selection phase of public construction projects. These findings are vital in discovering for the first-time factors influencing the success of the tender stage of public labor-based projects in Ghana and developing nations with similar socioeconomic characteristics.

Local and regional interactions between tidal stream turbines and coastal environment

An extended three-dimensional unstructured ocean model for simulating impacts of tidal stream turbines on tidal current, turbulence and surface waves has been applied to study the interactions between a tidal turbine farm and its surrounding environment. The present study aims to reveal three-dimensional local and regional changes due to the operation of a proposed turbine farm in natural coastal environment. Fine mesh size is assigned at the turbine farm location to capture the details of local wake dynamics, hydrodynamics and suspended sediment transport. Large geographic coverage of the model provides details of changes in regional features. Results showed that the proposed turbine farm comprised of 18 turbines (15–20 m in diameter) with approximately 20% power extraction from the average available power (averaged over five and half tidal cycles) led to local variation of surface elevation within the range of −10 to 3 mm, flow acceleration on both sides of the turbine farm, flow acceleration of ∼ 0.4 m/s near the bed in the vicinity of the turbine farm which caused bed shear stress to rise up to 2.5 N/m2 (corresponding to the critical stress of a range of fine gravel and finer sediment particles), locally increased TKE of 0.09 m2/s2, reduced wave height of 0.01–0.05 m, and upward sediment transport in the water column. On a regional scale, most of the changes on amplitude and phase of M2 constituent were observed within 10 km (∼ 15 times the array width) from the centre of the turbine farm, and the wake in terms of 95% flow rate recovery was found to be 9 km long (∼ 14 times the array width). Noticeable changes were also found in surface waves, bed shear stress and suspended sediment transport on regional scale as result of moderation in tidal and flow dynamics, although much less prominent than the local effects. It is recommended that consideration during the Environmental Impact Assessment stage of tidal stream energy projects should be given to an area that extends beyond the immediate vicinity of the planned turbine farm.

Fast and robust recombinant protein production utilizing episomal stable pools in WAVE bioreactors

Protein reagents are essential resources for several stages of drug discovery projects from structural biology and assay development through lead optimization. Depending on the aim of the project different amounts of pure protein are required. Small-scale expressions are initially used to determine the reachable levels of production and quality before scaling up protein reagent supply. Commonly, amounts of several hundreds of milligrams to grams are needed for different experiments, including structural investigations and activity evaluations, which require rather large cultivation volumes. This implies that cultivation of large volumes of either transiently transfected cells or stable pools/stable cell lines is needed. Hence, a production process that is scalable, speeds up the development projects, and increases the robustness of protein reagent quality throughout scales. Here we present a protein production pipeline with high scalability. We show that our protocols for protein production in Chinese hamster ovary cells allow for a seamless and efficient scale-up with robust product quality and high performance. The flexible scale of the production process, as shown here, allows for shorter lead times in drug discovery projects where there is a reagent demand for a specific protein or a set of target proteins.

Aided design decision-making framework for engineering projects considering cost and social benefits

PurposeCurrently, engineering project design lacks a design framework that fully combines subjective experience and objective data. This study develops an aided design decision-making framework to automatically output the optimal design alternative for engineering projects in a more efficient and objective mode, which synthesizes the design experience.Design/methodology/approachA database of design components is first constructed to facilitate the retrieval of data and the design alternative screening algorithm is proposed to automatically select all feasible design alternatives. Then back propagation (BP) neural network algorithm is introduced to predict the cost of all feasible design alternatives. Based on the gray relational degree-particle swarm optimization (GRD-PSO) algorithm, the optimal design alternative can be selected considering multiple objectives.FindingsThe case study shows that the BP neural network-cost prediction algorithm can well predict the cost of design alternatives, and the framework can be widely used at the design stage of most engineering projects. Design components with low sensitivity to design objectives have been obtained, allowing for the consideration of disregarding their impacts on design objectives in such situations requiring rapid decisions. Meanwhile, design components with high sensitivity to design objective weights have also been obtained, drawing special attention to the effects of changes in the importance of design objectives on the selection of these components. Simultaneously, the framework can be flexibly adjusted to different design objectives and identify key design components, providing decision reference for designers.Originality/valueThe framework proposed in this paper contributes to the knowledge of design decision-making by emphasizing the importance of combining objective data and subjective experience, whose significance is ignored in the existing literature.

Broadening Ethnographic Following: From Following Conflicts to Following Agreements and Silences in Vaccination Debates

ABSTRACT George Marcus’s methodology for multi-sited ethnography is widely discussed and applied in anthropology and the strategy of ‘following the conflict’ has been a fruitful approach to studying controversies and conflicts. Drawing on my shifting methodology in the initial stages of a digital ethnography project on vaccination-related online community forums, I explore ‘the war’ on vaccines using a broadened strategy that includes following agreements and silences within the controversy. By examining the debate in conjunction with medical anthropology research, I discuss how both vaccine-cautious and vaccine-confident forum members challenge conventional debate divisions, such as scientific–unscientific, evidential–anecdotal and genetic–environmental, while still adhering to medico-scientific discourses as zones of agreement. Whereas an agreement-oriented methodology contributes to research on liminal zones and reconfigured forms of bio-citizenship and literacy, the strategy of ‘following silences’ highlights the limits to liminality in a debate underpinned by adultism that silences the views of young people.

Status assessment of a recently reintroduced eurasian lynx (Lynx lynx) population in the Palatinate Forest, South-West Germany

To reinforce Eurasian lynx populations in central Europe, 20 lynx from Slovakia and Switzerland were translocated to the Palatinate Forest between 2016 and 2020. Using a systematic camera trapping array consisting of 80 camera trapping sites in a 1,000 km² study area located in the centre of the approximately 1,800 km² Palatinate Forest, we aim to describe the status of the population in the final stages of the reintroduction project in winter and spring 2019/20 and 2020/21. We also use our data to provide a first estimate of population density of the newly established population. With an estimate of 0.52 independent individuals per 100 km², population density in the Palatinate Forest was still significantly lower than the densities of well-established reintroduced populations. The number of independent individuals detected in the study area decreased from 15 individuals in 2019/20 to 11 individuals in 2020/21, thus significantly below the number of lynx translocated. The low abundance in the Palatinate Forest can be explained by the dispersal of several individuals to the Vosges (France), which, together with the Palatinate Forest, form a continuous area of suitable lynx habitat of approximately 8,000 km². Our results may thus reflect the status of a young population that can expand over a potentially large area. Nevertheless, in light of the low population density, we strongly recommend a synchronized and harmonized transboundary monitoring program to keep track of the development of this important Franco-German lynx population. In case population density remains low, supportive measures need to be considered.

Staging the Theatrical Public Sphere in The Laramie Project

Abstract Contemporary documentary theater has become a favored genre in scholarship to investigate the relationship between theater and the public sphere (Reinelt, “Promise”; Balme; Claycomb, Lurch). Drawing on Christopher B. Balme’s concept of the theatrical public sphere and other scholarship, I examine how The Laramie Project (2000) by Moisés Kaufman and the Tectonic Theater Project stages the idea of the public sphere and, in the process, rethinks the form of documentary performance. On one level, the play reflects a discursive turn in documentary practice as multiple narrative layers dramatize the collision of opposing value systems and civic voices in order to challenge established boundaries between the private and the public, the liberal and the conservative, the rural and the urban, poverty and wealth, life and art. The theatrical sphere is constructed as an imaginary space not just of rational debate but of negotiating questions of accountability by appealing to the affective engagement of the audience. On another level, I argue, the play operates as a metatheatrical piece, using strategies such as a narrator and anti-illusionism to establish the theatrical public sphere as a conceptual framework that fuses sociopolitical engagement with a self-reflexive theater practice.

Older Humans and Their Dogs

Loneliness and a lack of socialization can have a deteriorating effect on life experience and health. Unfortunately, loneliness is an experience often felt by older people, and interspecies companionship can provide valuable and daily interaction that is positive for well-being. In the place of another human, a dog may inhabit a role as a provider of emotional support. In Judith Butler’s sense of performative identity, there is a becoming of that which we do. Using an approach of working with (rather than on) people, this informs sensitive and sympathetic methodologies for an analysis of the significance and benefit of interspecies companionship for older people in the initial stages of my artistic research project, Dogs and the Elderly. Made with participants of the Alzheimer’s Society’s “Memory Cafés” in Nottingham and Lincolnshire (UK), the project demonstrates how interspecies companionship can be valuable for supporting the emotional health and wellbeing of older people. This illustrated photo and text article discusses how the project’s older humans and their dogs inhabit a togetherness within supportive interspecies relationships in various ways, and how this contributes to their lived experience. It explores the stories of a group of people, living with or supporting others with early-stage Alzheimer’s, who speak to companionship with their dogs to articulate the significance of the relationship from their perspective.

Modern Challenges of Adjusting the Effectiveness of the Application of Laws (on the Example of Tax and Legal Regulation)

The relevance of the research topic is determined by the current state of social relations. It is notedthat the analysis of modern social relations cannot be carried out outside the boundaries of significantchallenges that require not only their understanding, but also consideration in the relevant reform measures.The most important challenges today are the following: Russia's war with Ukraine; European integrationprocesses that characterize modern trends in Ukrainian development; digitization of all aspects of public life.Given the problems associated with this, the article defines both objective reasons that affect tax relations, aswell as requirements that are subjective in nature.The purpose of the article is to highlight problematic aspects of the state of modern legal regulation.Attention is focused on the fact that war, European integration and digitalization are among the mostinfluential factors in this aspect. It is clear that they cannot fail to influence the traditional legal means thatguarantee the effectiveness of tax legislation. These aspects are the subject of analysis.Traditional methods of scientific knowledge are used in the research, thanks to which a systematicidea is formed about the reasons for adjusting legal means of influence on tax relations. The characteristicsof the influence of martial law on tax regulation are carried out depending on the stages. The beginning ofthe first is associated with 2014, while the second - with 2022. Despite common features (narrowing of theterritories where Ukrainian jurisdiction exists, reduction of the tax base and tax-paying taxpayers, etc.),differences in the content of these stages have been singled out. European integration processes, whichreflect the movement of Ukraine towards the European community, provide for the adjustment of the natureand content of tax legislation in the following directions: a) adaptation of the current tax legislation ofUkraine to European requirements; b) consideration of European prescriptions at the stage of developmentof zocono projects; c) achieving a balance of acts of the national legislation system.Three areas of relations, which most fundamentally affect the legal status of tax regulation, havebeen studied. The prospects of tax changes depending on the state of war, the prospects of the impact ofharmonization of EU legislation and national legislation, the need to take into account the processes ofdigitalization of tax relations are considered.On the basis of the conducted research, conclusions were made and recommendations were maderegarding the harmonization of the prescriptions of both exclusively tax norms and tax norms on the borderwith other industry regulations. Adjustment of the current set of legislative norms determines the importanceof a systematic approach to the turnover of virtual assets. The formation of a generalized, systematicapproach to these relations is fundamentally important. In order to achieve such a state, it is very importantto supplement the private law means of regulating the circulation of virtual assets with effective tools ofpublic and legal influence (taxation, supervision, public control). The study analyzes the substantive factorsof the regulation of such relations proposed by the two draft laws.

Jane Drew and Minnette De Silva Pioneering Participatory Architecture in Mid-Century India and Sri Lanka

Jane Drew and Minnette De Silva made significant contributions to the architectural field, namely to the broader frameworks of the mid‑twentieth-century Modern Movement and tropical architecture. They also pioneered inclusive design processes, in line with the discussion of human factors that was just starting to fuel the architectural agenda. Peons’ Village in Chandigarh and Watapuluwa in Kandy are housing schemes resulting from participatory methodologies where both architects promoted dialogue with the populations and integrated regional specificities. The collective engagement, which occurred at different project stages, effectively involved future inhabitants in decision-making and is reflected in the outcome of the projects. Drew and De Silva’s socially engaged architecture envisioned project design as a co‑creation process, contributing to redefining the architect’s role, and aiming to foster a more equitable urban environment toward a better society.

Research ethics in a multilingual world: A guide to reflecting on language decisions in all disciplines

Doing research in a globalized context – regardless of the discipline – requires language decisions at different stages of the research process. Many of these language decisions have ethical implications. Existing literature and ethical guidance tend to focus on ethical concerns that arise in communication with participants who use a language different from the main research language. As this article shows, language decisions with potential ethical implications can occur in many additional ways. Two questions guided this work: how do language decisions and research ethics intersect at different stages of the research process, and what potential harm is related to language decisions and how can such concerns be mitigated? Relevant literature – combined with practical research experiences – show that language decisions can potentially result in harm at the conception stage of research projects, when working with participants, during data analysis, interpretation, and dissemination, as well as when managing a research project. Thus, the article highlights that the role of language-related ethical dilemmas is not only organizational (e.g., ensuring participants can understand what the research is about), but also social (e.g., developing trust and relationships in research teams) as well as ideological (e.g., awareness of power structures and diverse worldviews). In order to support researchers in globalized contexts, this article offers a reflective framework that complements regulatory guidance issued by ethical bodies and facilitates a deeper awareness of ethical implications related to language decisions in a multilingual world.

Architectural and artistic solutions of the OTC during the gentrification of soviet cinemas

In the professional environment of architects, there is concern about the formation of a trend of reconstruction and renovation of buildings and structures in large and major cities in order to develop urban infrastructure. The underestimation of the contribution of Soviet architecture to the cultural heritage of post-Soviet countries and countries of the socialist camp is noted. At the same time, the "new architecture" forms the urban environment under the stereotypes of homologation, which does not correspond to the socio-cultural demand of the glocalization of "digital nomads" seeking to live in eco-digital cities. The obsolescence of the "new architecture" is observed already at the project stage or in five years. In Moscow, the reconstruction program includes 39 Soviet cinemas in the peripheral zone of the city. Public and shopping complexes with underground levels are being built on the site of these cinemas. The article classifies the types of projects of Soviet cinemas and shopping centers, and also forms diagrams for their qualitative comparison. This eventually made it possible to evaluate the architectural and artistic contribution to the Moscow development of both Soviet cinemas and new shopping complexes, the continuity between them and differences in design principles.

Financial Literacy's Moderating Effect on Project Selection with Heuristic-Driven Biases: SMEs’ Entrepreneurial Market Development in Pakistan

Certain biases on various project stages influence projects. Based on the moderating influence of financial literacy, the effect of heuristic-driven biases on project selection is evaluated in this research. The study aimed to evaluate how heuristics-driven biases affected the project management environment. A questionnaire with a five-point Likert scale is used to gather quantitative data. The study's target demographic comprises project managers and other senior employees at Small and Medium Enterprises (SMEs) with more than five years of experience. This study involved 200 participants, but only 151 responses were deemed authentic. Convenience sampling is the study's methodology. SPSS and Smart PLS3 are used for data analysis. The findings show that three behavioural biases, availability, representativeness, and under-confidence, have a negligible influence on project selection, but two behavioural biases—overconfidence and anchoring have a favourable impact. The research asserts that individuals do not succumb to these biases in many SMEs. The findings indicate that financial literacy does not moderate the association between heuristic-driven biases and project selection. Entrepreneurs, managers, investors, and businesses will gain immensely. Business owners should detect heuristic-driven biases to make better judgements. Controlling heuristic biases helps entrepreneurs make better decisions and implement productive business strategies. This research will help business owners manage their heuristic biases and grab business opportunities without making costly mistakes. This study offers a unique opportunity and the potential to improve the knowledge of entrepreneurial managers about the impact of heuristic-driven biases in the context of project management.

Digital twin-based quantification of carbon emission from foundation pit construction: A case study of a station in Shanghai Metro

This study focused on achieving the carbon peaking and carbon neutrality goal. A carbon emission calculation method based on the entire process of excavation construction and the emission factor method for the foundation pit construction of a metro station was proposed. This method facilitated quantitative calculation of total carbon emissions in metro foundation pit engineering, which was then incorporated into a self-designed digital twin platform to drive sustainability efforts. The proposed calculation approach was verified in the foundation pit of Huangpi South Road Station (Shanghai Metro Line No. 14). (1) The pit construction process of the targeted metro station emitted 127,439t of carbon dioxide equivalent. (2) From the material perspective, reinforcing steel and concrete accounted for a significant proportion of the overall carbon emissions. Whereas, from the construction perspective, the engineering process of supporting structures accounted for a considerable proportion of the carbon emissions. (3) A comparative analysis of different construction zones revealed that the carbon emissions during the construction stage of the metro pit project were closely related to the amount of earthwork and size of the deep excavation engineering. Practically, the discovered knowledge of carbon emission characteristics can be visualized in a digital twin.

DESIGNING FOR SUSTAINABILITY: A SHOPPING MALL ANALYZING LIFE CYCLE IMPACT OF STRUCTURAL DESIGNS AND MATERIALS

The lifespan of construction projects entails significant consumption of resources, energy, and space. Due to sustainability awareness throughout all stages of construction projects, Life Cycle Assessment (LCA) is one of the tools used for examining the impacts of a product or process at all stages of the product or process's life cycle, including conception, production, use, and disposal. In order to gain a deeper understanding of the choice of design and construction materials, a case study was conducted for a shopping mall. It included a comparison of the environmental impacts of utilizing the LCA approach throughout their lifespan for two structural engineering designs: concrete and steel. The life-cycle environmental impacts of the structures are evaluated throughout their life cycle using SimaPro software and the midpoint technique of the ReCiPe method. Based on the results, it was concluded that the concrete structure design had a greater negative environmental impact over the course of its life cycle than the steel structure design. As a result, the study emphasizes the significant environmental effects of building material choices as well as the value of life cycle assessment in selecting between various design options prior to the construction phase.
