In construction projects, conducting dynamic load tests on all piles proves impractical. Selective testing estimates bearing capacity, while the remaining piles rely on penetration depth for management. This approach, however, faces reliability issues due to varying conditions among piles. Technological advancements, such as non-contact hammers and sensors, have enhanced the accuracy of penetration depth measurements during final driving. Nonetheless, relying solely on penetration depth for construction and quality management remains problematic. This study, therefore, focuses on enhancing the use of driving formulas to improve pile quality management, particularly for the widely used pre-stressed high-strength concrete (PHC) piles. To improve pile quality management, existing driving formulas underwent review and refinement. Utilizing 258 dynamic load test data from various sites, the Hiley, Gates, and Danish formulas underwent validation through statistical analysis and graphical comparison. Enhancements to the Gates formula, achieved through curve fitting with actual data and the application of segment-based coefficients, demonstrated increased accuracy in bearing capacity estimation. These improvements offer a more reliable approach to pile quality management in construction projects.

Целью статьи является проведение исследования, анализа и уточнение существующей терминологии в области управления проектами как части менеджмента, выявление особенностей его применения в управлении инвестиционно-строительными проектам. Актуальность выбранной цели обусловлена отсутствием единства в терминологическом определении базовых понятий, а успешное управление проектами в строительной отрасли требует особого внимания к специфической терминологии и методологиям. Автор приводит подробный обзор существующих научных источников по данной тематике. Особое внимание уделяется таким терминам, как «проект», «управление проектом», на основании чего делается вывод об определенной терминологической разобщенности. На основе анализа теоретических аспектов управления проектами автор предлагает рассматривать проект как комплекс взаимосвязанных действий по достижению определенных уникальных целей. Под строительным проектом следует подразумевать строительно-инвестиционный проект, который является комплексом взаимосвязанных действий по созданию объектов недвижимости, при ограничениях, присущих данного рода проектам. В процессе исследования выявляются особенности толкования этих базовых терминов по отношению к строительной отрасли, рассматриваются определения «управление инвестиционно-строительным проектом», «строительно-инвестиционный проект», так как наличие базовых определений не уточняет значения данного термина в конкретной сфере в строительстве. Сделано предложение, что совершенствование научной базы, выявление отдельных тенденций ее развития положительно влияет на отрасль, которая на нее опирается. The purpose of the article is to conduct research, analysis and clarification of existing terminology in the field of project management as part of management, to identify the features of its application in the management of investment and construction projects. The relevance of the chosen goal is due to the lack of unity in the terminological definition of basic concepts, and successful project management in the construction industry requires special attention to specific terminology and methodologies. The author provides a detailed overview of existing scientific sources on this topic. Special attention is paid to such terms as "project", "project management", on the basis of which a conclusion is drawn about a certain terminological disunity. Based on the analysis of the theoretical aspects of project management, the author suggests considering the project as a set of interrelated actions to achieve certain unique goals. A construction project should be understood as a construction and investment project, which is a set of interrelated actions to create real estate objects, with the limitations inherent in this kind of projects. In the course of the research, the peculiarities of the interpretation of these basic terms in relation to the construction industry are revealed, the definitions of "investment and construction project management", "construction and investment project" are considered, since the presence of basic definitions does not clarify the meaning of this term in a specific area in our case, in construction. It is suggested that the improvement of the scientific base, the identification of individual trends in its development has a positive effect on the industry that relies on it.

Risk management in construction projects has great importance through its impact on the basic objectives of the construction projects, as controlling the risks of the construction projects helps reduce cost overruns and time overruns and improve the quality of the construction projects. This paper aims to highlight the role of BIM in risk management in construction projects by generating a predictive risk model using Monte Carlo simulation to analyze a number of risks and generating a 3D model and 4D model to show the effect of risks. The predictive risk model can help project managers control the risks that affect the construction projects and enhance communication between all stakeholders for the project. The methodology was applied to two risk scenarios, the optimistic scenario for risks, and the pessimistic scenario for risks in one of the construction projects in Iraqi through the use of four commercial programs working together. The study concluded that the building information modeling technique has great importance in reducing the risks affecting the construction project by showing the effect of these risks during the project’s construction phases and controlling them.
