Unlocking the full potential of reality capture for construction project cost monitoring: a mixed review

Purpose Digital data acquisition is crucial for operations in the digital transformation era. Reality capture (RC) has made an immeasurable contribution to various fields, especially in the built environment. This paper aims to review RC applications, potentials, limitations and the extent to which RC can be adopted for cost monitoring of construction projects. Design/methodology/approach A mixed-method approach, using Bibliometric analysis and the PRISMA framework, was used to review and analyse 112 peer-reviewed journal articles from the Scopus and Web of Science databases. Findings The study reveals RC has been applied in various areas in the built environment, but health and safety, cost and labour productivity monitoring have received little or no attention. It is proposed that RC can significantly support cost monitoring owing to its ability to acquire accurate and quick digital as-built 3D point cloud data, which contains rich measurement points for the valuation of work done. Research limitations/implications The study’s conclusions are based only on the Scopus and Web of Science data sets. Only English language documents were approved, whereas others may be in other languages. The research is a non-validation of findings using empirical data to confirm the data obtained from RC literature. Practical implications This paper highlights the importance of RC for cost monitoring in construction projects, filling knowledge gaps and enhancing project outcomes. Social implications The implementation of RC in the era of the digital revolution has the potential to improve project delivery around the world today. Every project’s success is largely determined by the availability of precise and detailed digital data. RC applications have pushed for more sustainable design, construction and operations in the built environment. Originality/value The study has given research trends on the extent of RC applications, potentials, limitations and future directions.

Practice for Continuous Effect of Technology Transfer in Bridge Maintenance and Management

As part of international cooperation efforts by the Japan International Cooperation Agency, Japan has implemented technical cooperation projects for bridge maintenance and management in several countries. The authors conducted technology transfer for bridge inspection and repair in technical cooperation projects in Egypt and the Philippines. This paper describes the past shortcomings and future support methods required based on these efforts as well as maintenance efforts in Japan. At the organizational level, we examined goals and strategies for fostering “effective ownership” and the nature of the PDCA (Plan-Do-Check-Action) cycle, including effectiveness measurement. At the individual engineer level, we examined the need to accumulate and pass on experience. Through these studies, the sustainable management cycle was examined. As a result, the studies identify the importance of flexibility in project monitoring and revision. It is necessary to determine the evaluation period based on actual achievement rather than time constraints. Besides, it is important to elastically reconsider indicators even at higher levels as well as effective countermeasures.

Feasibility of targeted active seismic monitoring of geological carbon storage using refracted waves

Active seismic monitoring is a powerful technique that can be employed for conformance and assurance monitoring in geological carbon storage (GCS). This technology was successfully deployed in small-scale research studies and large-scale commercial projects. Usually, in land time-lapse surveys, to ensure time-lapse data quality, the seismic survey is designed to have a very high trace density. This increases the cost of the survey and usually results in high-quality data covering only a very limited area. While this is a good approach if the detailed plume image is required, massive uptake GCS would require the monitoring to be cost-effective. Therefore, it is important to explore the possibility of using a series of daisy-chained wells instrumented with distributed acoustic sensors and paired to permanent seismic sources as a basis for such a system.To this end, we propose using head waves instead of reflected waves in large-scale projects for conformance monitoring (and, maybe, large leakage detection). Using a cartoon model of CarbonNet Pelican site as a motivation, we perform a feasibility study through seismic modelling. We also simulate a similar monitoring approach for a forthcoming shallow fault injection at the CO2CRC's Otway site in the Australian State of Victoria. This experiment can be viewed as a scaled model for larger injections. Based on these modelling results, we provide a short overview of the further field experiments that can be used to validate the proposed approach.

Social Determinants of Health Among Persons Living with HIV Impact Important Health Outcomes in Michigan.

Addressing social determinants of health (SDOH) is a national priority for improving quality of life and addressing obstacles to accessing care for people living with HIV (PLWH). Utilizing the Oregon Social Determinants of HIV Health Index and CDC's Medical Monitoring Project, we examined the association between social determinants of health and various HIV clinical outcomes and quality of life indicators, including stigma and mental health, for people living with HIV in Michigan. We calculated estimates of SDOHs, clinical outcomes, stigma, and mental health using weighted percentages and prevalence ratios with predicted marginal means, adjusting for age, race/ethnicity, and gender/sexual orientation. Compared with PLWH reporting 0-1 SDOH challenges, those reporting ≥ 4 SDOH challenges were more likely to miss ≥ 1 HIV care appointment (aPR: 2.57, 95% CI 1.70-3.88), have symptoms of depression (aPR: 4.03, 95% CI 2.68-6.05) and anxiety (aPR: 3.55, 95% CI 2.25-5.61), and less likely to have 100% antiretroviral therapy (ART) adherence (aPR: 0.62, 95% CI 0.50-0.78) and sustained viral suppression (aPR: 0.77, 95% CI 0.65-0.90). Stigma scores were highest for those reporting ≥ 4 SDOH challenges. Our findings indicate significant associations between SDOH and adverse HIV health and quality of life outcomes which can inform and direct federal, state, and local strategies aimed at improving these outcomes. Linking PLWH to social support services and providing mental health screening and care services could benefit their mental and emotional well-being, leading to better healthcare outcomes.

Beached seabirds as plastic biomonitors in Brazil from the Beach Monitoring Project of the Santos Basin (PMP-BS)

Bioindicator species are useful to monitor wildlife exposure to plastic pollution, and responses to plastic leakage and policy interventions. Here we explore the biomonitoring potential of different seabird and shorebirds species across six years of monitoring in Brazil. Using the necropsy stranding database of the Beach Monitoring Project of the Santos Basin (PMP-BS), we evaluated i) the frequency of birds-plastic interactions in Brazil; ii) whether plastic interactions have changed through time and in different coastal regions; and iii) potential bioindicators for monitoring the exposure of seabirds to plastic in the nearshore South Atlantic Ocean. We found 37 species that had ingested plastic, including ten new records, found that the rates of tube-nosed seabirds increased through time, and suggested two potential species. We discuss the potential for biomonitoring marine pollution in the South Atlantic Ocean using PMP-BS, providing a scheme for a better plastic pollution monitoring in Brazil.

Network Analysis and Control System in Mega Projects: The Case of PICASP Erasmus Project

Network Analysis achieved some significant results in recent years thanks to advances in technology and in the approach to organisational networks. Less exciting were the results obtained with Mega Projects. These projects show high risk with regards to results, to the compliance of the budget and to the realization of the entire project. So far, the response of Mega Projects contracting authorities is to ask those presenting the project proposals to increase the number of controls and connected indexes without obtaining, almost until now, an increase in project performance. This paper examines the proposal to transfer some results of network analysis to the performance monitoring of Mega Projects. Starting from the case of Erasmus PICASP Project for the creation of Pilot courses and new didactics for teachers training in cultural tourism for the development of Caspian Area, the paper proposes an evolutionary model of cycles of simplification and complexification of the networks control systems. The approach of Practice Enterprise which allows the members of the project networks to acquire the practice of teamwork right from the early stages of planning, and, once the project starts case risks or emergencies arise, will be applied within his model.

Calliphora rohdendorfi (Grunin, 1966) (Diptera: Calliphoridae): a new blow fly in the Italian fauna detected in Calabrian Apennines

Within the family Calliphoridae, the genus Calliphora Robineau-Desvoidy, 1830, includes species of medical, veterinary and forensic relevance. This study reports for the first time the presence of Calliphora rohdendorfi (Grunin, 1966) in the Italian territory, namely in Calabrian Apennines (Southern Italy). The adults of the species were captured by bait bottle and yellow pan traps within a monitoring project of Diptera Brachycera involving Parco Nazionale dell’Aspromonte (Aspromonte National Park), Parco Nazionale della Sila (Sila National Park) and Parco Naturale Regionale delle Serre (Natural Regional Park of Serre), between 2018 and 2021. Calliphora rohdendorfi was identified on detailed morphological bases of both sexes. This was the first description of the general morphology of the female and its terminalia through digital photographs acquired by stereomicroscopy. The species was captured in pine and beech forests at an altitude between 1010 and 1820 m a.s.l. in shaded mountain areas. Prior to the finding in Southern Italy, this species showed an unusually disjointed distribution in Caucasus, Germany and Poland, thus the presence of C. rohdendorfi in Calabrian Apennines provides new and interesting data that require further investigation, because the species could play a role as flower visitor, pollinator and forensic indicator.

Lack of local genetic representation in one of the regions with the highest bird species richness, the Peruvian Amazonia.

Peru ranks among the three countries with the highest bird species diversity globally and a majority of those species are found in the Peruvian Amazon. However, birds in this area are currently facing serious anthropogenic threats. Genetic and genomic methods are becoming important tools for avian biodiversity monitoring and conservation planning. Comprehensive molecular libraries that are publicly available are key to the effective deployment of these tools. We analyze the information gaps for four molecular markers in the most important genetic sequence databases, Barcode of Life Data Systems (BOLD) and NCBI GenBank, for bird species of the Peruvian Amazonia. We found that 64% of Peruvian Amazonian bird species have gene sequences for COI, 59.5% have CYTB sequences, 16.4% have 12S sequences, and only 0.6% have 18S sequences. However, these numbers decrease drastically to 4.3% for COI sequences when we only consider specimens sampled in Peru. Our data also showed that 43.8% of Peruvian Amazonian endemic species (n = 32) are missing sequences of any screened marker uploaded to GenBank or BOLD. Our results will encourage and guide efforts of the scientific community to complete reference libraries for Peruvian avian species that will be useful for future DNA-based monitoring projects that include birds.

Why new scientific information is important for native fish conservation: A case study from the humpback chub (Gila cypha) in the Grand Canyon, U.S.A.

Abstract Habitat descriptions found in critical habitat designations and recovery plans are important for protecting endangered species. However, in order to protect critical habitat, it is necessary to update descriptions of habitat use when range shifts occur or new studies change the understanding of habitat use. This study examined the habitat use of a threatened desert fish to determine whether current habitat use matched the descriptions in recovery documents. Recovery documents describe humpback chub (Gila cypha) as being dependent on rocky, canyon‐bound habitats during all life stages, but recent surveys found humpback chub in open, silt‐laden habitats, suggesting this species may be able to occupy a wider range of habitats. Hoop net catch data from a long‐term monitoring project in the Colorado River were used to compare catches of two size classes: juvenile/subadult (<200 mm total length [TL]) and adult humpback chub (≥200 mm TL). Catch information was analysed on an individual net scale and on a geological segment scale using generalized linear mixed models. There was no difference in juvenile/subadult humpback chub catch between hoop nets set in rocky habitat compared with habitat with only fine sediment. Humpback chub catch for all life stages in a river segment characterized by silt banks exceeded or was not significantly different from catch in rocky segments. This case study demonstrates the importance of revisiting habitat descriptions, sampling in areas outside known or expected habitat and incorporating new data related to range expansion or habitat changes in recovery strategies to better describe and protect habitats that can support imperilled species.

A Comprehensive Analysis of Monitoring and Control Mechanisms in Operational Relocation Project at Limkokwing University, Botswana

The analysis of project monitoring and control processes holds paramount significance in project management and delivery, attracting considerable attention within academic discourse. The study explores the intricacies of project monitoring and control, particularly in the context of operational relocation at Limkokwing University of Creative Technology Botswana. The study employs a comprehensive survey methodology, encompassing all project team members and university management, stratified by department, and tasked with responding to structured questionnaire items. Analysis of the gathered data unveils proficient performance in project monitoring and control, underscored by systematic reviews of project progress and interface oversight. Based on the insights gleaned from this investigation, the study urgently recommends the establishment of a specialized monitoring and control unit or function within the university’s organizational framework. This is not just a suggestion, but a crucial step to address developmental exigencies or challenges, and to enhance the prospects of successful project outcomes. However, the study also identified certain barriers to success, including inadequate staff coordination, a need for more skilled personnel with requisite experience, and resistance to organizational change. Therefore, further research is necessary to refine and optimize the efficacy of monitoring and control processes, taking into account these key factors.

Digitization Workflow for Data Mining in Production Technology applied to a Feed Axis of a CNC Milling Machine

Condition monitoring and predictive maintenance applications receive ongoing scientific attention in production technology. Larger companies, especially machine and component manufacturers, already offer related products. Small and medium-sized enterprises (SMEs) in particular show interest in developing and offering solutions in this market themselves to gain economic advantages, to improve resource utilization of their machines or to be able to offer these advantages to their own customers. In the development process, however, they often encounter problems already in the digitization of the machines. The first hurdle is to obtain an analysis-capable data set. This is due to the fact that common and established general data mining development process models, such as CRISP-DM, do not focus on production technology, causing difficulties for engineers during deployment. A problem with existing process models is the limited practicality in the engineering domain due to restricted adaptability. In a previous paper, a guideline for engineers for data mining suitable digitization of production machines was developed in order to solve these problems. The related results were provided in the context of a project for condition monitoring of mixing machines. In this paper, the proposed method is applied to components of a 5-axis CNC milling machine in three different monitoring use cases. A complete workflow is presented, including effect analysis, sensor selection, formulation of predictive scenarios, data preparation, training of machine learning algorithms and vizualization. Data and documentation are provided alongside this publication.

Enhanced pedagogical methodologies for facilitating the progression of the Master’s final exam between the professor and the student, focusing on the project titled: Vita Nova - The rehabilitation of nature, architecture, and the spirit

An article that unites theory and practice, architecture as a union between a final-year architecture student and a professor or advisor at the Faculty of Architecture of the University of Lisbon, throughout the course and throughout the monitoring of the final master's project. This accompaniment began in the first semester of the fourth year, and since then it has been a construction between teacher and student where a series of pedagogical intentions have been explored, from the deep reading and correlation between architecture and nature through the graphic process recorded daily to the most appropriate rehabilitation methodologies in the explored architecture. This whole system was divided into several phases, all of them divided by the themes and chapters addressed in the project. This work culminated in a deeper understanding of the methods of organization and design of a different work. The uninterrupted monitoring by the teacher towards the student resulted in numerous debates and different conceptions, so that the work in question had the best possible result. This procedure resulted in a continuous search for a clearer understanding through pedagogical incitement, guiding the work so that it took the most appropriate course for the student's project. Nature and rehabilitation were the central themes of all the work, where the aim was to establish qualities that cut across the two areas of knowledge. The main objective has always been the research for architecture and rehabilitation and the deep relationship between the built architecture, the one that is intended to be built, and the surrounding nature, through the study for the best possible conclusion of the Master's Final Proof.

Chalk stream restoration: Physical and ecological responses to gravel augmentation.

To mitigate the morphological and ecological impacts of direct (e.g. dredging) and indirect (e.g. damaged river function) sediment loss, gravel augmentation is commonly practiced in river systems globally. Despite this, the effectiveness of this practice remains poorly understood, especially in less often considered systems such as chalk streams which present uncommon conditions (e.g. low stream power, stable flow) and may respond to interventions in ways that differ from systems more commonly studied. This study quantified immediate (0-1 years) and short-term (1-2 years) physical and ecological responses to gravel augmentation at two English chalk stream restoration sites: Home Stream (HS; River Test) and East Lodge (EL; River Itchen). We quantified habitat (depth, velocity, substrate composition), cover of different macrophytes, and macroinvertebrate (before-after-control-impact) abundance and community structure. Restoration reduced depth and increased gravel cover in both sites and decreased the cover of filamentous green algae in HS. Macroinvertebrate communities became more dominated by silt-intolerant taxa, while abundance [HS only] and taxon richness increased 1-2 years post-restoration. Whilst the responses found were generally positive in light of the restoration goals, the effects varied across sites, post-restoration time periods and ecological groups, emphasising the need for the more holistic monitoring of restoration projects considering community-level responses at different sites and systems over ecologically relevant timescales. This will help inform on the generality and longevity of responses and provide the evidence needed to develop sound restoration practice.

ПОРІВНЯЛЬНИЙ АНАЛІЗ МОДЕЛЕЙ ТА МЕТОДІВ УПРАВЛІННЯ МАРКЕТИНГОВИМИ ПРОЕКТАМИ

The article examines the importance and effectiveness of using the project management methodology to ensure timely and budget-effective implementation of projects in accordance with customer requirements. The author emphasizes that project management is a strategic process that encompasses project initiation, planning, execution, monitoring, control, and closure. Special attention is paid to the role of project management in marketing, where complexity and constant dynamics require careful planning and execution. Using project management techniques in marketing teams can improve planning, improve efficiency and productivity, improve communication and collaboration, provide greater control over budget and resources, and lead to improved campaign results. Various marketing project management methodologies, their characteristics and differences are studied. The waterfall cascade model is defined as a sequential approach to dividing a project into fixed tasks, which can be effective for short and well-defined projects, but not suitable for complex and long-term tasks. Agile flexible model and Scrum are defined as fundamentally different approaches based on collaboration, iterability and speed. Agile emphasizes individuals over processes, while Scrum is defined by short iterations and a team motivation system. The Critical Path Method (CPM) and Critical Chain Marketing Project Management (CCPM) are defined as methodologies aimed at determining and optimizing project completion times. Integrated Marketing Project Management (IPM) is seen as an approach focused on standardizing and sharing processes across the organization, which can be useful for large creative agencies. Methodologies (PRiSM, PRINCE2, PMI PMBOK) expand the range of available approaches to marketing project management. Each of them has its own features and applications depending on the specific needs and characteristics of the project. The article provides a comprehensive overview of various methodologies and their relevance to specific conditions and types of marketing projects.

Community Participation and Sustainability of Youth Livelihood Projects in Uganda: A Case of Northern Uganda Youth Entrepreneurship Project (NUYEP)

Purpose: This study examined the effect of community participation on sustainability of youth livelihood projects in Uganda, using a case of Northern Uganda Youth Entrepreneurship Project (NUYEP). The specific objectives of the study were to determine the effect of community participation in planning, implementation and monitoring on sustainability of NUYEP. Methodology: The study adopted a cross-sectional design with both qualitative and quantitative research approaches. Data was collected from a sample of 152 project beneficiaries and 10 local leaders using a self-administered questionnaire and interview guide. The data was analyzed using Spearman’s rank correlation and regression analysis with the help of SPSS v25. Findings: The study found a significant positive relationship between community participation in planning (rs= 0.406**, p=0.000); participation in implementation (rs= 0.655**, p=0.000); and participation in monitoring (rs= 0.365**, p = 0.000) and project sustainability. Collectively, the predictor variables explain 52.1% of the variation in project sustainability. Conclusion: It is concluded that community participation improves the sustainability of Youth Livelihood projects. Recommendations: It is recommended that future projects do prioritize community participation in project definition, implementation and monitoring. This should be a key aspect of project programming. Contribution: This study contributes to the understanding of how community participation is aiding the sustainability of the NUYEP project. In addition, most studies do explore the aspect of project performance with very few handling the aspect of project sustainability especially involving the youth programmes.

Monitoring bird migration using nocturnal flight calls on the East Asian–Australasian Flyway: a case from Beijing

Summary Migratory birds are experiencing widespread population declines, underscoring the urgency of effective conservation actions. Long-term monitoring of migratory birds, especially during migration, is crucial for such actions yet remains technically challenging. Bioacoustic monitoring of nocturnal flight calls (NFCs) constitutes a promising technique to monitor migratory birds during migration. Such monitoring has increased in North America and Europe, but its application on the East Asian–Australasian Flyway (EAAF) remains limited. Here, we present findings from an NFC monitoring project conducted at a recording station in central Beijing, China over four migration seasons. From around 3,350 hours of recording effort, we manually extracted and identified 84,135 NFCs, involving at least 111 species or species groups that are associated with a wide range of habitat types. We also found that NFCs provided additional information on species’ migration phenology in comparison with citizen science observation data. To our knowledge, this study is the first formal investigation of bird migration using NFC monitoring on the EAAF, serving as a proof-of-concept case for wider, long-term monitoring efforts in this traditionally understudied region. Our findings also highlight the significance of incorporating migratory bird conservation into urban planning and land management practices.

Pan-Canadian review of community-based monitoring projects and their capacity to enhance environmental monitoring programs for cumulative effects assessments

While community-based monitoring (CBM) can support meaningful participation of the public in environmental decision-making, it remains unclear if and how CBM can support western science approaches to biophysical studies within cumulative effects assessment (CEA). We scored 40 Canadian CBM projects on their ability to enhance CEA's western science approaches to environmental monitoring. We used multivariate analyses to determine if the highest-scoring projects shared characteristics that could inform the design of CBMs to support CEA. Cluster analysis and non-metric multi-dimensional scaling ordination revealed that highest-scoring projects were distinct from lower scoring projects, and the Similarity Percentages Routine identified characteristics that differentiated these projects. The highest-scoring projects involved non-profit organizations as bridging organizations that coordinated community participation and received funding and in-kind support from provincial/territorial government agencies. Participants in these projects collected measurements and samples using standardized protocols described in training manuals. Their data were publicly accessible in georeferenced databases and were used for baseline studies and resource management. There are existing CBM projects in Canada that thus appear well positioned to enhance western science approaches to CEA. Further study is required to identify how CBM projects can be designed to braid Indigenous and western science approaches to mutually enhance CEA methods.

Application of BIM Technology in Building Water Supply and Drainage Network Security Monitoring Engineering

With the acceleration of urbanization, we are paying more and more attention to the safety and reliability of building water supply and drainage systems. Faced with various limitations of traditional monitoring methods, such as insufficient real-time performance and difficulties in data collection, we propose a new solution that combines BIM (Building Information Modeling) technology and the Internet of Things. This system not only enables real-time monitoring, but also quickly addresses security risks, greatly improving management efficiency and system security. In terms of system stability, the standard deviation of water pressure based on BIM technology is 1.1 kPa and the standard deviation of water flow rate is 0.2 L/s. Moreover, the building water supply and drainage network security monitoring project based on BIM technology can quickly and accurately respond to various security incidents. From the data conclusion, it can be seen that the system based on BIM technology has efficient, accurate, stable, and secure monitoring capabilities.

Postepidemic Epidemiology of Porcine Epidemic Diarrhea Virus in the United States

Porcine epidemic diarrhea virus (PEDV) emerged in the United States (U.S.) swine population in 2013, initiating an initial significant epidemic followed by a state of endemicity in the U.S. Despite continued monitoring, the epidemiology of PEDV during its endemic phase remains inadequately researched. Our study aimed to characterize the spatial–temporal distribution of postepidemic PEDV cases in the U.S. breeding herd and identify associated risk factors. Data from 1089 breeding farms in 27 states, reported to the Morrison Swine Health Monitoring Project from July 2014 to June 2021, were analyzed. We stratified the data into six U.S. regions and employed SaTScan for spatiotemporal permutation and cluster analysis. Survival analysis was used to assess risk factors. A notable seasonal clustering of PEDV cases was observed in winter (January–March; p = 0.001, relative risk = 2.2) with regional variation. Ten high‐rate spatial–temporal clusters (p < 0.05) were identified ranging from 2.5 to 833.7 km2 and lasting 1–5 months, occurring in four regions between 2015 and 2021. For the study period, a total of 625 cases of PEDV were recorded on 372 farms. The total number of PEDV cases decreased from 95 breeding farms in 32 counties (2014–2015) to 53 farms in 28 counties (2020–2021), indicating an overall reduction in occurrence and spatial extent. Feed mitigants demonstrated a protective effect, significantly reducing the risk of PEDV occurrence (hazard ratio = 0.3, p = 0.003), while air filtration systems exhibited marginal benefits (hazard ratio = 0.3, p = 0.06). Other important risk factors included county farm density with farms in high‐density regions (>31 farms/100 km2) being 1.3 times more likely to experience outbreaks than in medium‐density regions (13–31 farms/1000 km2; p < 0.001). Additionally, farms in region E had higher odds of outbreaks compared to region B. The overall decline in PEDV cases and reduced spatial extent reflect industry efforts in postepidemic control and elimination. The protective effects of feed mitigants warrant further investigation. Our findings underscore the opportunity for coordinated efforts to eliminate PEDV in the U.S. and emphasize the need for comprehensive risk profiling associated with industry practices.
