OS DESAFIOS DA IMPLANTAÇÃO DA METODOLOGIA BIM EM ESCRITÓRIOS DE ARQUITETURA NA CIDADE DE VITÓRIA DA CONQUISTA – BA

Building Information Modeling (BIM) can be defined as a methodology that uses 3D models and their detailed data on all elements involved in a civil construction project. As society is a constantly evolving organism, the Construction Industry has faced the need to adapt in order to deliver better productivity results, thereby meeting increasingly meticulous demands more effectively. Scientific research has shown that the use of BIM can reduce project completion times in infrastructure by up to half. Given this, why is the number of architecture and urban planning firms in Vitória da Conquista – BA, that use this methodology still so minimal? This article, through bibliographic research as well as opinion surveys with architects and urban planners from the city of Vitória da Conquista, aims to demonstrate the challenges of implementing Building Information Modeling (BIM) methodology in offices in Vitória da Conquista – BA. Thus, the points discussed in this work will provide a reflection on this question, the conclusion of which will depend on the awareness and experience of each participating architect, as well as the robustness of the understandings used to support the content in the following sections.

Efficient optimization of robust project scheduling for industry 4.0: A hybrid approach based on machine learning and meta-heuristic algorithms

This research contributes significantly to the domain of Industry 4.0 by offering a nuanced approach to the multi-objective optimization of the resource-constrained project scheduling problem (RCPSP) under uncertainty. Focused on the context of smart product platforming, this study introduces a novel methodology that not only considers traditional factors like time and cost but also incorporates quality and risk aspects, crucial for personalized product fulfillment. In this regard, a comprehensive four-objective mathematical model is proposed to minimize project completion time, total project costs, and project risks while simultaneously enhancing overall project quality. Real-world uncertainty is acknowledged through the incorporation of uncertain parameters for the time, risk, and quality associated with each project activity. To address this uncertainty, a robust optimization method is applied based on Bertsimas and Sim's approach. Moreover, to optimize the proposed model, the Hybrid Red Deer and Genetic Algorithm (HRDGA) is proposed, which is leveraging a machine learning approach for clustering solutions. The numerical results demonstrate that increasing the project budget by 30% leads to an upward trend in total project costs and a reduction in the minimum acceptable quality by 10%–30% results in a decreasing trend in the total project cost. This research emphasizes the adoption of Industry 4.0 enabling technology within the project scheduling platform, particularly highlighting its significance for personalized product fulfillment.

Measuring the Performance of Industrialized Building System (IBS) Construction on Projects Towards Achieving IR 4.0 in Malaysia- Contractor’s Perspective

According to prolonged project completion times, excessive costs, and inadequate building products, the majority of construction projects are seen as underperforming. Alternatively, stakeholders are encouraged to move from conventional to Industrialized Building Systems (IBS) in line with today's technology. Previous studies show the performance of IBS practices in the Malaysian construction industry is still at a low level even though the government has diversified promotions and issued instructions for 70% of IBS use in government projects. These selection criteria affect contractors' performance of IBS practices and need to be done in a systematic way, along with current technology trends and sustainability. Content validity in IBS practice performance is an important step in instrument development. Content validity in IBS practice performance is an important step in instrument development. Therefore, this research aims to evaluate the content validity of the performance effectiveness of IBS practices by using the content validity index (CVI) and modified Kappa sensitivity. In an effort to accomplish the objectives of this study, a questionnaire was created using construct items that were taken from earlier research projects by various researcher. A panel of selected experts who are experienced in the field of IBS, such as CIDB, ​​JKR and contractors have reviewed and evaluated pig instruments to ensure the relevance of each item. The final instrument contains 39 items that are valid and considered permanent and all items will be tested again in the next study. The results showed that the S-CVI/AVE for every item met every requirement and received an outstanding rating for every assessment.

Assessment of Concrete Formwork Practices in Bahir Dar City, Ethiopia

Formwork is among the most determinant factors affecting the cost and completion time of construction projects. In this study, the erection practices, challenges, types, quality and cost of formwork on active building construction projects in Bahir Dar were assessed. The study uses, Questionnaires, site observations and oral interviews with project managers, office and site Engineers, construction managers and carpenters were used to organize and analyse data. From assessment, most of the contractors have given less attention to formwork erection and safety issues. Since the principal criteria for formwork selection are cost and traditional formwork erection, it impacts construction safety and reduces the concrete finishing and quality. Formwork erection is left as the task of carpenters and labourers. There is no proper supervision of the quality of formworks that guarantees construction workers' safety so it is vulnerable to physical injuries and affects employee’s health. From the study, timber formwork is the most dominant type of formwork used for the construction of slabs, beams, columns and stairs due to its availability and low cost. Burnt oil is used as a releasing agent in all construction projects that causes undesirable outputs in concrete surfaces.

Linear Scheduling Method-Based Multi-Objective Optimization for Off-Site Construction Manufacturing

Optimal production scheduling in off-site construction is hindered by the lack of comprehensive methods that simultaneously addresses workforce allocation, realistic labor productivity, workstation idle time (WIT), work-in-progress (WIP), and project completion time (PCT). To overcome these limitations, this paper introduces a hybrid planning and scheduling method that integrates the linear scheduling method reflecting workforce allocation, Monte Carlo simulation for estimating realistic labor productivity, and a multi-objective optimization model to minimize WIT, WIP, and PCT concurrently. The proposed method is validated using the Taillard instance benchmark dataset, and a panelized production line located in Edmonton, Canada. As a result, the proposed method is effective in generating realistic and optimal production schedules, achieving reductions of 5.2 % in PCT, 41.45 % in WIT, and 56.42 % in WIP. These findings are crucial for industry professionals aiming to improve efficiency in the production line and provide a foundation for further research in off-site construction scheduling.

Impact of leasing transactions on business development in Kyrgyzstan

The purpose of this study was to determine how leasing transactions contribute to business modernisation in Kyrgyzstan. The study used survey methods and semi-structured interviews with company representatives, followed by statistical analysis of the collected data to determine changes in productivity, operating costs, and investment payback period. In particular, the results showed that 90% of the surveyed agricultural enterprises reported a 25-30% increase in productivity after using leasing to purchase machinery, which was confirmed by analysing data on the reduction of repair and maintenance costs for old equipment. In transport logistics, 85% of the companies indicated a reduction in operating costs and improvement of logistics processes due to fleet renewal through leasing programmes, which also contributed to an increase in the customer base by 15-20%. In the construction sector, the use of leasing allowed 82% of companies to reduce project completion time by 20-25%, which was due to the acquisition of new construction equipment through leasing, which can accelerate the performance of work and improve the quality of projects. In the manufacturing sector, 70% of companies reported a positive impact of leasing on their production capacity, but a longer payback period was identified, which requires the development of specialised leasing programmes with more flexible terms for industrial enterprises. The results of the study confirmed the important role of leasing as a financial instrument for the modernisation of enterprises in Kyrgyzstan, but also reveal the need to improve the access of small enterprises to leasing programmes and adapt the conditions for sectors with a long investment cycle, such as manufacturing

Application of Business Information Management in Cross-border Real Estate Project Management

Cross-border real estate project management is inherently challenging due to its complexity and diversity. This study investigates the efficacy of business information management systems (BIMS) in managing such projects and employs machine learning models for performance prediction analysis. Utilizing data from 250 valid questionnaires and 15 in-depth interviews, multiple regression analysis, classification algorithms, and clustering analysis models were applied. The results indicate that system quality, information quality, and service quality significantly enhance project management efficiency and user satisfaction. Specifically, the adoption of BIMS reduces average project completion time and cost overrun rates, thereby improving management effectiveness. Commercial real estate projects reported the highest average investment at $70 million, mixed-use projects exhibited the longest average completion time of 25 months, and residential real estate projects achieved the highest management efficiency score, averaging 8.0. The regression model's coefficient of determination (R²) was 0.68, the classification model achieved an 85% accuracy in identifying risk factors, and clustering analysis categorized projects into high-efficiency management, risk-concentrated, and resource-intensive types. These findings underscore the substantial value of BIMS in cross-border real estate project management, providing robust management tools and decision support. However, the study's limitations include a small sample size and restricted data sources. Future research should aim to expand the sample size and incorporate more diverse data sources to enhance the findings' generalizability and accuracy.

DEVELOPMENT STRATEGY FOR THE SCIENTIFIC EDITION “RUSSIAN JOURNAL OF EDUCATION AND PSYCHOLOGY”

Background. Russian scientific journals joined the international market of scientific publications quite late, which actualises the development of a strategy for entering this market and complicates the realisation of the strategy as such in the environment of tough competition on the part of experienced and stable players thereof. Purpose. The purpose is to elaborate a strategy for the development of the “Russian Journal of Education and Psychology” for its introduction to the international market. Materials and methods. The research sources are represented by statutory acts, statistical materials and results of the author’s empirical research. The research is based on the systemic approach; the strategy of the journal is based on the ideas of the positioning school; the main method of business planning is economic analysis. Results. The growth of competition in the domestic market, along with the gradual approximation of the Russian scientific journals evaluation system to the global practice and the universal quality criteria, proved to be the conditions inspiring the change in the strategy of the scientific edition “Russian Journal of Education and Psychology”. The detailed analysis of the internal and external environment of the journal made it possible to form a self-contained range of strategic alternatives among which the entry to the international market was the most appropriate way to meet the objectives of the publishing house and the interests of the proprietor (who is also the project customer). Securing the journal’s work in accordance with the requirements of the international scientometric databases, for its inclusion in the Scopus and (or) Web of Science, became a new strategic goal of the journal. The new goal changed the concept and mission of the journal with regard to the customer’s wish to preserve the edition’s traditional values. Changes in marketing and peer reviewing were identified as the main transformation areas for which new functional strategies were developed. The overall project plan envisages the solution of other targets as well, but it is the tasks connected with the journal distribution and the change in the work of the editorial board and in the business aspects of reviewing that became extremely significant in terms of their timing and involved financial costs. The project team comprising current employees is supposed to cope with possible risks with respect to project completion time, while the financial resources of the publishing house will allow it to overcome the financial risks of the project without any assistance. Even in case of failure to achieve the strategic goal, due to its high risk, the journal’s key performance indicators will be improved through the increased share of high-quality articles; by optimising and tightening the review process, active promotion of the journal in the national and foreign markets; by attracting a numerous audience (authors, readers) and expanding the number and diversity of stakeholders.
