In the construction project of the Pasuruan Regency BPBD building complex which is currently still running, there have been problems related to the schedule for the implementation of its activities. The problem in question is the delay in the schedule for the implementation of its activities. where the results of the progress realization are not in accordance with the schedule plan, through this paper an evaluation is carried out related to performance in the field through an approach using the Earned Value Method. The data analysis process is carried out by calculating analysis indicators including BCWS, BCWP and ACWP. The results of the performance evaluation of the Pasuruan Regency BPBD building complex construction project using the Earned Value method show that the project has a negative deviation in the activity implementation schedule. The cost performance indicator on this project shows a Cost Performance Index (CPI) value of 1.137, which means that the costs incurred are greater than planned. While the time performance indicator shows a Schedule Performance Index (SPI) value of 0.949, which means the project is delayed from the planned schedule.

The integration of BIM in the application of green building materials in construction projects

In recent years, with the growing call for sustainable development, green building materials, which are of great meaning for reducing resource and environmental impacts, have attracted more and more attention. However, in China, a country with frequent construction activities and high resource consumption, the application of green building materials in construction projects still faces challenges. Building Information Modelling (BIM) as an emerging technology in the construction industry can increase the adoption rate of green building materials in construction projects. The aim of this study is to identify the barriers encountered in the application of green building materials in Chinese construction projects, and to propose corresponding improvement measures by integrating BIM in the decision making. This study adapted a qualitative research method, using semi-structured interviews as a research tool. A total of 6 respondents (including project managers, architects, engineers, and researchers) from Chinese construction companies and research institutions collected interview data, and used Nvivo software to analyze and summarize. The results of this study show that although the application of green building materials in construction projects in China still faces challenges, including market acceptance and supply chain issues, cost and economic feasibility issues, and lack of relevant technology and knowledge. In addition, the study found that BIM technology made a great contribution in promoting the application of green building materials. Through BIM technology, the whole life cycle information management such as material selection, engineering simulation and performance evaluation of construction projects can be carried out, so as to improve the application of green building materials. By exploring the obstacles to the application of green building materials in China’s construction projects and combining with the promotion of BIM technology, this study puts forward a series of specific suggestions and solutions to foster the application of green building materials. This research has made certain theoretical and practical contributions to foster the application of green building materials for the sustainable development of China's construction industry.

Safety performance evaluation of construction projects in Egypt

In Egypt, the construction industry employs about 20% of the total work force in the local market. The health and safety (H&S) performance evaluation is adopted mainly to control H&S risks in construction sites. As such, there is a need to measure the safety performance in construction sites in a way that is proactive rather than just relying on interactive procedures. The main goal of this study is to develop an indicator to evaluate safety performance on construction sites. This is achieved through two basic steps. First, factors that affect safety performance in construction projects are determined by reviewing literature and conducting personal interviews. A total of 47 factors were collected. Then, a questionnaire was conducted to determine the most important factors that affect the H&S of construction projects in Egypt. The incentives and safety training were among the most important factors. Second, an index to evaluate safety performance has been developed. The purpose of this evaluation is to create a determinate through which construction sites safety could be assessed. The proposed model will be a useful tool to assist project managers and safety inspectors to assess safety performance in construction sites and thus help build safety regulations.

The general objective of this study was to determine the degree to which Rwandan road building performance is influenced by the evaluation of road projects. The specific goals were to examine the road construction project evaluation process and its effect on Rwanda's road construction performance, to assess the impact of formative project evaluation on Rwanda's road construction performance, and to evaluate the impact of summative project evaluation on Rwanda's road construction performance. Descriptive research design was adopted for this study as it assessed a sample at one specific point in time without trying to make inferences or causal statements; the target population is composed of sixty-six (66) fulltime workers of NPD – COTRACO Ltd in Rwanda who spends their working hours of the day in road construction activities in this company. The sampling technique was census. In this research work, questionnaires, and documentation data collection techniques were used. The collected data were analyzed using SPSS (version 23.0) software. It was first edited, categorized, or coded and computerized. Mean and standard deviation were utilized in descriptive statistics, while regression analysis was employed in inferential statistics to identify and demonstrate the strength of the link between the variables. The findings show that process evaluation relates positively with performance of road construction projects and cannot be concluded that this variable affects the dependent variable since (β=0.063, p˃0.05; p=0.360); There is a positive relationship between formative evaluation and performance of road construction of NPD-COTRACO as results are statistically significant since (β=0.875, p<0.5; p=0.000); and summative evaluation relates positively with performance of road construction of NPD-COTRACO and cannot be concluded that this variable affects the dependent variable since (β=0.59, p˃0.5; p=0.265). The recommendation that construction companies need to have a budget covering the whole of the project as the budget affects the performance of road construction implementation was provided. Keywords: Project Evaluation, Performance of Roads Construction, Nyarutarama Property Developers COTRACO, Rwanda

Research on Intelligent Prediction of Engineering Cost Based on Artificial Intelligence

However, due to the limited engineering information in the investment stage of the project, the estimation of construction cost generally has the disadvantages of large error and long preparation time. Therefore, how to calculate the cost (or investment) of engineering projects accurately, reasonably and quickly is a matter of great concern to engineering project practitioners and researchers. Through the combination of systematic theoretical analysis and practical work experience, the index system for construction project cost prediction is constructed. The artificial intelligence (AI) theory of neural network (NN) is selected, and the basic principle, network model and prediction method of construction project cost prediction with this method are systematically analyzed. As a theoretical model, a new construction project cost prediction model is constructed. This paper mainly studies the application of AI methods in the field of construction project evaluation. Three kinds of AI evaluation models are established by using particle swarm optimization artificial neural network (ANN) and case-based reasoning to predict the construction project evaluation, and their effectiveness is verified by examples.

Evaluation of Power Grid Investment Decision-Making with Mixed Binomial Coefficient and Coefficient of Variation

The investment evaluation of power grid construction projects is a necessary link for power grid companies to carry out power grid construction. In the traditional evaluation process, it is generally based on the original index scores or similar schemes for comparison and decision-making. There are problems of simple methods and insufficient theoretical support. Fully considering various factors in the investment process of power grid construction, a set of rating index system with three-level hierarchical structure is constructed with actual demand as the standard. The evaluation model is verified and analyzed by an example.

Soil function assessment in high‐mountain environments: Testing the SEPP tool in a ski resort in the Italian Alps

AbstractSoil function assessment (SFA) plays an important role in evaluating the impact of management practices, land‐use changes and construction work. The Soil Evaluation for Planning Procedures (SEPP) tool is one of the few existing SFA tools that allow automated SFA. It was originally developed to address land‐use planning issues, which traditionally play a minor role in high‐mountain areas. Hence, the SEPP tool has not yet been applied to such environments. In this study, we tested the SEPP performance on high‐mountain soils previously altered by construction work and land‐use changes. Specifically, we evaluated soil data from 16 ski runs and 16 paired control sites in the Italian Alps, aiming to reflect land‐use‐driven differences in soil properties in the SFA results. The study revealed options to adapt SEPP assessment methods if high‐mountain soils with special characteristics (e.g. shallowness or high coarse fragment content) are investigated. The main adaptation options are the consideration of further soil parameters and the adjustment of thresholds of function fulfilment levels. However, the assessment results of the current SEPP version already reflect the most relevant impacts of ski run construction on the soils in the study area: fulfilment of some of the soil functions was impaired and that of others improved, while most remained at a comparable level. We conclude that SFA with the SEPP tool provides valuable support for the evaluation of construction projects and land‐use change in high‐mountain environments. However, the significance of SFA can be improved by considering the intrinsic properties of high‐mountain soils.

Improving models for sustainability evaluation of construction projects in the initiation and planning processes

The object of this study is the management processes of «sustainable construction». Sustainability is considered through the application of management processes that, in addition to the traditional tasks for construction projects, also outline the tasks of a wider context. Strategies and production practices of «sustainable construction» involve taking into account environmental, social and economic factors that affect a wide range of stakeholders and the overall condition of the built space. In this regard, the issue of applying management processes in the construction industry that ensure proper organizational and technological sustainability of projects is also being updated. This article aims to fill the existing information and methodological gap in the processes of assessing the sustainability of construction project management processes. A correlation method was applied to determine the interdependencies of the characteristics of the use of tools and methods in the processes of managing construction projects with the values of sustainable development 5Р (Product, Proses, People, Planet, and Prosperity). Highlighting the characteristics of permanence in project management processes helps to explain the difference in approaches for ensuring the internal sustainability of the construction object and the sustainable management of a construction project. A comprehensive methodology for quantitative assessment of sustainable construction project management in the initiation and planning processes under conditions of uncertainty is proposed. The relative importance of construction project management processes and subcategories of sustainable development of the construction site is taken into account. Basic mathematical models of sustainability assessment have been developed: balanced in all areas of knowledge of construction project management for each process, balanced across all construction project management processes at the «Initiation» and «Planning» phases for each category of sustainable development, and integral assessment of sustainability of construction project management processes.

Objective: To investigate the application of GBZ/T 220.2-2009 "The Specification of Radiological Protection Assessment for Occupational Hazard in Construction Project-Part 2: Radiotherapy Facility" in health management institutions, and to understand the scientificity, practicability and problems existing in the implementation of the standard. Methods: The method of multistage stratified sampling and questionnaire survey were used to collect the standard application status among 96 radiological health managers who had participated in the evaluation of radiotherapy facility construction projects in 6 provinces and cities from November 2020 to April 2021. A descriptive statistical analysis method was used to analyze the basic information of the survey object, the knowledge of the standard, the publicity and implementation of the standard. Results: The radiological health management personnel mainly came from health supervision agencies (62.5%, 60/96) , and 86.5% (83/96) were engaged in the pre-evaluation of radiotherapy device construction project and the approval and supervision of control effect evaluation. The awareness rate and training rate of radiological health managers on GBZ/T 220.2-2009 were 88.5% (85/96) and 31.3% (30/96) , respectively. 89.6% (86/96) managers thought it could meet the needs of radiotherapy facility construction project approval or supervision. 49.0% (47/96) of managers believed that the standard needed to be revised. Conclusion: The content of GBZ/T 220.2-2009 is basically scientific and reasonable, but the publicity, implementation and training of radiological health administrator still need to be strengthened. It is suggested to revise some clauses in the standard that do not meet the requirements.

A Decision Support System for Optimal Building Cold Source Selection

Building energy consumption is increasingly becoming a matter of global concern. A key aspect of this is the nature of building cold source systems and their effectiveness. However, choosing the cold source for a building is a complex decision-making process. The traditional evaluation method is relatively simple, and it is difficult to comprehensively consider multiple factors and their mutual influences, and it is even more difficult to increase the consideration of the whole life-cycle cost on this basis. Especially in China, the cost of extra-large public projects invested and constructed by the government plays a significant role in the decision-making process, and it should not be affected by other factors to change the decision-making. Therefore, this paper proposes a new decision-making system, which is based on value engineering (VE) and combined with analytic network process (ANP) to conduct a comprehensive study of project decision-making. Based on existing approaches to construction project evaluation and the selection of cold source systems, we establish an evaluation index for building cold source system functional models and network structures. This approach can take into account the impact of cost on decisions. We then present the results of a simulation-based case study of potential central air-conditioning cold source system solutions for the new Xiang’an New Airport in Xiamen, China. The corresponding value coefficients for conventional electric refrigeration, ice storage, and water storage were found to be 0.8262, 1.0049, and 1.2442, respectively. This suggests that water storage-based cooling offers the best technical and economic benefits for this project. It also confirms that the proposed decision support system can identify the modes with the highest value coefficients, which is one of the most effective methods for selecting a building cold source system scheme. Therefore, the system has the potential to support the effective selection of other building cold source schemes.

In the modern conditions of the development of the world economy, a significant problem is being formed regarding the effectiveness of assessing the market value of construction projects from the point of view of institutional and private investors. This problem is caused by the instability and uncertainty of the development of the world economy, on the one hand, as well as the imperfection and lack of modernity of traditional methods of assessing the market value of construction projects, on the other. Within the framework of the current development of the situation in the global economy, the implementation of construction projects is associated with significant risks, which creates significant threats in the field of investment efficiency. This issue requires improving the process of assessing the market value of construction projects from the point of view of an institutional investor. The existing models of evaluation of construction projects are focused mainly on the profitability indicator and do not take into account two key factors: the dynamics of potential growth in the market value of the project and the interests of stakeholders as key persons able to influence the cost of the construction project. The model proposed in the framework of this study includes two key advantages in its structure, it allows you to calculate the growth potential of the market value of a construction project in an unstable economic situation. In addition, this model takes into account the interests of key groups of stakeholders, which makes it possible to determine that this model of estimating the market value of a construction project takes into account both quantitative and qualitative factors affecting the cost of the project. The model is based on the paradigm of comparative evaluation of construction projects from the point of view of an institutional investor, the calculation of the final results of the effectiveness of individual construction projects, according to this model, allows you to identify the most priority and effective from the point of view of a potential investor. This model makes it possible to assess the growth potential of the market value of a construction project both at the pre-investment stage and at the stage of direct investment. This model fully corresponds to modern trends in the field of investor orientation mainly on the potential growth rates of the market value of a construction project.

Socio-Economic Impacts of Occurrences on Railways

The paper presents partial outputs of an applied research project aimed at evaluating the socio-economic impacts of occurrences emerging on the railway and their reflection into the economic evaluation of railway construction projects. The article builds on the research results presented within previous scientific articles where the unit impacts of sub-categories of occurrences on the Czech railways were determined using a detailed Database of Occurrences for the 2011-2018 period. These impacts were related both to one railway station and one kilometre of the wide line for the occurrence sub-categories. The values obtained were subsequently verified on case studies of specific railway infrastructure projects implemented in the Czech Republic. The results of the case studies raised the need to create an alternative methodology for the evaluation of socio-economic impacts, which would more accurately reflect the real situation on the railway. The aim of the paper is to modify the originally designed methodology for evaluating the socio-economic impacts of occurrences into a new methodology, which would relate the impacts of occurrences only to a standard kilometre of wide line, i.e. without taking account of separate impacts of occurrences on one railway station. The proposed methodology was verified on a case study, which compares the real values of socio-economic impacts emerging on the railway in the period under research, the values determined using the original methodology and the values determined according to the newly modified methodology.

Life Cycle Assessment of Industrial Building Construction and Recovery Potential. Case Studies in Seville

In Spain, most businesses are medium to small size enterprises, representing 90% of the total, but there is a lack of studies of the types of building this sector uses. The main objective of this paper is to present a method for the evaluation of small industrial construction projects to facilitate the introduction of eco-efficient solutions. For this, it is necessary to identify the most representative buildings and the aspects of these which have the most environmental impact. A methodology in place for the evaluation of dwelling construction is adapted, for the first time, to evaluate industrial buildings. The construction solutions characterized are those traditionally used in the sector, as identified through 87 surveys. A standardized classification of work units is proposed to enable the use of environmental product information, such as eco-labels and/or EPD, and LCA databases. The carbon footprint (CF) and water footprint (WF) are the indicators selected because of their straightforward message. Finally, a comparative analysis is performed showing the high recycling potential of concrete and cement which, along with metals and aggregates, control the impact in terms of CF. With respect to the WF indicator, plastic substitute aggregates are among the materials with the greatest impact.

Strategic Learning and Knowledge Management of Technological Innovation in Safety Evaluation Planning of Construction Projects

The safety evaluation of construction projects is a very important problem. In the current study, the new smart methods especially for the complexity and variability of construction safety evaluation are absent. Combined with the engineering examples, this paper analyzes the sensitive factors that affect the construction project safety and makes discretizating of influencing factors based on expert and BIM technique. Based on BIM and Bayesian network, this paper established a new construction project safety evaluation model and presented the hybrid methods of strategic learning and knowledge management of technological innovation in construction project safety evaluation. Combined with the example of underground traffic engineering of Zhengzhou city comprehensive transportation hub, the Bayesian network was used to predict its security level. The probability of the safety level of the project in grade 3 is 0.614. Compared to other evaluation methods, presented hybrid method is more intelligent in strategic learning and knowledge management of technological innovation. Through the Bayesian network sensitivity analysis, we can know that the sensitivity factor of the construction project safety in the project is the construction risk, the continuous operation time, the protective measures, the material risk, and the number of maintenance. Presented detailed computational methods and steps in this paper can be used to improve the level of construction project safety effectively and help construction managers to take more effective control measures to prevent or reduce the occurrence of security incidents.
