In recent years, as projects have become more complex, their problems have become bigger, so achieving success in the project has become the most important concern of project managers. Since success depends on many factors and one of the most important factors is the project's human resources. In this study, we examine the development of human resources. On the other hand, considering that the construction industry is very wide, for more accuracy, the focus of this study is only on the building field. Therefore, the purpose of this article is to evaluate the importance and strategy of human resource development in construction companies in Tehran. be Therefore, we have reviewed relevant relevant articles to find out the importance of human resource development in the construction industry, and then 35 contracting companies in Tehran, which are active in the field of building construction, have been examined in the field of human resource development. The findings show that most of the studied contracting companies accept human resources as an important resource, but unfortunately, they do not have a comprehensive and executive plan for the development and training of their human resources

Knowledge Management in project contexts, especially in construction projects, means learning from successful experiences in projects and organizations to prevent repetitive errors and improve project execution more optimally. These actions lead to reducing the number of mistakes, levels of stress, and challenges, ultimately resulting in project execution aligned with valid principles and standards. These measures lead to the satisfaction of managers in client organizations, consultants, contractors, and even beneficiaries. Implementing a knowledge management maturity model in an organization helps assess its progress in formal and comprehensive knowledge management implementation. Maturity modelling is used as a formal method to describe the knowledge management development process. This research aims to evaluate the level of knowledge management maturity in the construction company "Kayson," which is active in Iran's water industry. The objective of this research is to identify the existing gaps in knowledge management implementation and strive to improve the knowledge management process in the construction sector, with the aim of enhancing competitive advantage and efficiency in this industry. The research was conducted in a descriptive survey method, and the statistical population included all managers and senior experts of the Kayson company in the year 1401 (Iranian calendar). The evaluation of knowledge management was performed using the Asian Productivity Organization (APO) Knowledge Management Maturity Model. The results of the evaluation indicate that the Kayson company is at the initial level of the APO Knowledge Management Maturity Model. The highest scores are related to the components of knowledge processes, knowledge management leadership, and human resources. However, other components have scores lower than the average and require more attention from Kayson company managers. Therefore, based on the obtained results, Kayson needs to improve its knowledge management performance in certain areas, and it is recommended to make more efforts to enhance learning and innovation components.

The purpose of this research is to analyze the role of integrated components of sustainability in the construction industry in the construction projects of Imam Khomeini Port. For this purpose, a main hypothesis and three sub-hypotheses were developed. From the point of view of the purpose of this research, it is a development-oriented applied research, and from the point of view of methodology, it is descriptive-analytical (quantitative). The statistical population of this research includes specialists and construction experts of the Imam Khomeini Port Engineering System Organization, and the sample size was selected according to Kersey and Morgan's table by simple random sampling method of 120 people. The method of collecting information is library and field methods. Data analysis was done in two parts, descriptive statistics and inferential statistics using Pearson correlation coefficient, regression analysis and Friedman test by spss software. The findings indicate the confirmation of research hypotheses at a significance level of less than 0.05. Based on this, indicators of economic sustainability, social sustainability and environmental sustainability affect the success of construction projects.

The most important issue in developing countries is the lack of proper infrastructures to facilitate the welfare of society and deal with problems in a desirable way. Due to the nature of infrastructures, the implementation of such projects requires significant funding, which, especially in developing countries, governments do not have enough capacity, so we must pay close attention to attract the new methods to finance projects. Therefore, it is necessary to use methods or models to determine the appropriate financing method for each organization according to its risk endurable level. The present study intends to provide a framework for determining the level of risk of financing methods in order to select the appropriate method in each project. In the first phase of the proposed framework be developing the qualitative method called content analysis, coding of interviews with experts and applying the Fuzzy AHP method, 17 risk criteria in the form of 7 main criteria including financing costs, risk of timely provision of resources, repayment structure The risk of interest rate fluctuations, the risk of exchange rate fluctuations, the risk of non-timely realization of project revenues and the risk of macroeconomic variables were identified and weighted. In the second phase, a fuzzy expert system was presented to predict the level of risk of financing methods. The results of the research in identifying the criteria showed that the risk of non-realization of project revenues in a timely manner, the economy risks and financing costs had the highest priority in the risk of project financing methods. Also, in the part of fuzzy expert system, firstly, in the development of the model, a new method was used to limit the number of rules in the knowledge base, and secondly, according to the validation performed, the accuracy of the model was determined to be 88%.

Open communication between people working in the construction industry has led to the creation of a new complexity in the interactions. In order to solve the safety issue, in addition to the necessity of examining the problem itself, it is indispensable to examine the related issues as much as possible. The construction workshops are complex systems of human resources whose core is extensive patterns between formal and informal relations. The proper understanding of construction project managers about the influence of informal network relations on the performance of formal relations leads to the suitable exploitation of limited resources in construction workshops and ultimately helps to increase productivity. The results of this research in a construction workshop in Tehran, Iran, showed that almost all factors had a pivotal role and centrality as much as the desired occupation based on a workshop chart in the formal network relations; but communication between people is formed based on personality, racial, linguistic and other characteristics in the informal network relations. These relationships by casting a shadow on formal relations lead to a failure to achieve safety objectives and instructions. Therefore, the existence of ethnic and cultural links between the project manager and the Health and Safety Executive (HSE) with other employees at the workshop will increase productivity in the workshop safety.

In the construction industry: investigation of innovation success faction is a fundamental step in codification and planning for technical innovation. The development of the construction industry is one of the indication of the growth of countries and accounts for the largest share of fixed capital accumulation and the highest allotment Employment. According to the aim of this research is identification and ranking of key factors affecting innovation the success, in construction projects in Isfahan, using Analytic Network Process (ANP) method; after library search, interviews and using a questionnaire from 14 industry experts '' key success the factors affecting innovation success in construction'' identified. These factors categorized in three groups: government factors, organizational factors, and knowledge management factors and relation between them identified. For the final ranking, a paired comparisons questionnaire were distributed, between 20 experts in the project of Isfahan International Conference Center and the Abshar residential towers then data analyzed using the Analytic Network Process methods and Super Decision software. According to the Analytic Network Process results in top management commitment for the organizational factors, creating and supporting R&‌D institutions for governmental factors and the knowledge acquisition and developing among the factors of knowledge management have the most weight.

The construction industry is known as one of the most dangerous industries in terms of work-related losses, injury rates, and workers' compensation. Safety in construction is one of the most important issues due to the large number of accidents and deaths in this industry. The issue of safety has always been of great interest to researchers due to the history of accidents in the construction industry and many studies have been conducted in various fields related to safety. The purpose of this study is to identify and rank the components of safety management in construction projects. The present study is applied in terms of purpose and descriptive in terms of the nature of the method. In order to collect data, questionnaires were prepared and multi-criteria decision making methods (test and evaluation decision making method and network analysis method) were used Completed by ten safety experts with at least five years of experience in construction projects in the city of Shiraz. The collected data were analyzed by Excel and SuperDeicisions software. The results showed that the components of the presence of supervisors and trained engineers in the field of safety, training of personnel and personal protective equipment, have the most weight.
