Preface to Cost Management in Electrical Engineering Projects: Due to the unique characteristics of electrical engineering projects, management becomes somewhat complex. This article explores the control of costs during the construction phase. As cost management plays a crucial role in the entire project, it has a direct impact on its efficiency. The quality of cost management work directly affects the progress of the project; therefore, it is necessary to analyze the existing problems and propose effective solutions in order to promote the development of the electrical engineering industry. 1 Overview of Cost Management in Power Engineering 1.1 Concept During the construction phase of power engineering projects, cost management is an integral part of the entire process and represents a comprehensive management approach. Engineering cost management is based on the budget approved by the enterprise; it involves cost control and management, and by taking into account the scope and value of the budget, it ensures that control and management across the entire process are carried out within the approved budget limits. When managing cost-effectiveness, saving funds is a key approach to improving the efficient use of resources, preventing waste, and thereby enhancing the economic benefits of power engineering projects. Cost management is a key aspect of enterprise management, having a direct impact on the economic efficiency of the company. 1.2 Features In people’s daily lives, electricity is an essential material foundation. Various engineering projects are characterized by complex construction environments and long project durations, which makes unified management a challenge. Therefore, in the actual work process, it is necessary to strictly control construction resources and manage them in phases, taking into account the specifics of the project to prepare properly for its construction. 2 Problems in the cost management of power engineering during the construction phase: In power engineering, cost management has a direct impact on overall efficiency. It is essential to have an accurate understanding of cost management in order to ensure cost reduction. In electrical engineering, a great deal of human and financial resources are required; failure to plan and manage them properly can result in significant losses for the company. Therefore, the existing problems are discussed below. 2.1 Cost management and supervision need to be improved. Without proper supervision and management, the quality and efficiency of any project are affected. In the case of power projects, a comprehensive set of management methods is necessary to ensure the smooth progress of the work, and this applies equally to cost management. It is essential to supervise every stage of the construction process and maintain thorough oversight, so as to prevent costs from exceeding the allocated budget; otherwise, it will be difficult to keep things under control. With economic development and the updating of various policies, industries must also raise relevant standards and improve the professional competence of their staff in order to promote high-quality growth for enterprises. Therefore, in management work, it is necessary to change traditional management approaches, properly control development costs, and manage investment levels effectively, ensuring the efficient allocation and utilization of various resources in order to improve the economic efficiency of the enterprise. 2.2 Overemphasis on profits at the expense of management: In power enterprises, there is often an excessive focus on making profits, while management is neglected. This mistaken approach leads to a failure to consider the appropriate costs associated with design and materials, which in turn affects the quality of the work and results in financial losses. Therefore, as businesses grow, they need to pay sufficient attention to management tasks, giving top priority to management during the construction phase, and by establishing various systems to facilitate the smooth progress of cost management. 2.3 Lack of a sound cost management system: At present, in the process of corporate development, most enterprise managers lack professional competence; they have insufficient theoretical knowledge and practical skills. As a result, many problems arise in management tasks, and it is not possible to accurately predict cash flow, which leads to overruns in project costs. The lack of effective calculations for cost estimation affects the project timeline and increases corporate costs. At this time, it is necessary to improve the professional competence of managers, select individuals with high technical expertise for management roles, and conduct a thorough analysis of the work performed by staff in order to facilitate the smooth progress of management tasks. 2.4 Failure to keep up with the pace of technological advancement: In the process of power engineering construction, as materials and construction techniques continue to evolve and new technologies are constantly developed, companies that fail to keep up with these changes do not have a thorough understanding of the current state of technological development. Therefore, to stay competitive in a fierce market, it is necessary to learn advanced technologies, keep up with the pace of technological advancement, and improve the economic efficiency of the enterprise. 2.5 The professional skills and competence of cost management personnel need to be improved. Compared with other types of projects, power engineering is more systematic; therefore, higher demands are placed on the professional competence and technical skills of those involved in cost management. In practice, when carrying out control, managers must not only possess theoretical knowledge but also have experience in cost management and an understanding of legal regulations, so as to ensure scientific and rational management and control throughout the process, thereby enhancing the economic efficiency of the enterprise. However, among those responsible for cost management in the electricity sector, most lack professional competence. Some possess extensive theoretical knowledge but lack practical experience, while others have some practical skills yet lack the necessary theoretical knowledge, which prevents them from mastering the relevant techniques effectively. This leads to problems in cost management and hinders improvements in cost control levels. 3 Control Strategies for Power Engineering Cost Management during the Construction Phase 3.1 Preparation Work ① The person in charge of the power project determines the start date in order to ensure smooth progress of the project in the future. When issues such as land acquisition are involved in electrical engineering projects, strict adherence to the established document standards is required, and professionals are responsible for calculating the related costs. ②During the construction process, reasonable control is exercised over the procurement of equipment and materials, thereby improving both the quality of these materials and the supervision work, as well as ensuring effective cost management. 3.2 Improving cost budgeting: During the construction of power projects, it is not sufficient to focus solely on managing the costs during the construction phase; effective management is also necessary for the tasks carried out before construction begins. At the start of a project, a cost plan is formulated and a maximum cost budget is calculated; if the actual costs during construction exceed this maximum amount, corresponding adjustments must be made. Therefore, it is necessary to carefully select cost management personnel, choosing those with high professional competence to handle these tasks. Work should be carried out with the goal of reducing costs and improving quality; market prices for materials should be investigated on-site, the best solution determined, and accurate cost control implemented in order to enhance the economic efficiency of the enterprise. 3.3 Cost control in the decision-making process: In the construction of power engineering projects, the decision-making stage serves as an important foundation for ensuring the orderly progress of the project, and it has a certain impact on the effectiveness of cost management. Therefore, power companies should do a good job in cost management to effectively improve their economic performance. In the decision-making process, the cost estimation work is influenced by the decision-makers’ practical skills and mindset; if they lack an understanding of cost estimation, it directly affects the quality of this work. Therefore, during the management process, the relevant departments must investigate the factors that affect project costs, and submit the collected data to decision-makers as an important basis for their decisions. This helps to improve the level of management of electrical engineering costs and ensures the smooth progress of projects. 3.4 Cost control during the design process In electrical engineering, once a project is approved, the design phase becomes a crucial stage for cost management and control. During the design of various options, the materials required for the project have a direct impact on the overall cost of the project. Therefore, sufficient attention must be paid during the design phase. Firstly, during the design process of electrical engineering projects, designers establish a reasonable budget for the costs based on actual needs and project specifics, and determine the investment amount. Through appropriate cost management strategies, they improve the level of cost and expense control. Secondly, strictly review the engineering design work, identify any shortcomings, and make timely corrections. Additionally, proper cost management and budgeting should be applied to every stage of construction in order to reduce waste during the building process. In addition, designers must also conduct comparative analyses of the various proposed solutions in order to select the most reasonable one, thereby reducing costs and ensuring that construction expenses are kept under proper control. 3.5 Control of the costs of mechanical equipment and materials: During construction, mechanical equipment is essential; therefore, it is very important to manage it properly. Therefore, regarding construction equipment and materials, it is necessary to develop reasonable management plans and select appropriate equipment based on actual conditions, in order to reduce the company’s costs and facilitate the efficient completion of projects. 3.6 Improving the professional competence of cost management personnel: In the process of cost management in power engineering, it is necessary for cost managers to possess professional theoretical knowledge and an understanding of relevant laws and regulations. In addition, they need to have certain executive skills, and by continuously gaining experience, they can enhance their level of cost management. Therefore, in order to effectively improve the professional competence and technical skills of cost estimation personnel, it is necessary to provide them with regular training, explain the matters that require attention, and enable them to take effective action when problems arise, thus enhancing the capabilities of these cost management professionals. 3.7 Ensuring proper control over final settlement work: In the process of project cost management, final settlement is an important stage, as well as the final one. Cost management personnel must also maintain a serious attitude toward the final stage, uphold good professional ethics, and conduct thorough reviews of the settlement items. Cost audits must be conducted in strict accordance with relevant standard requirements; if any issues are found, they should be addressed promptly to ensure that every aspect is accurate, thereby facilitating the smooth progress of power project implementation. 4 Conclusion In summary, as electric power projects continue to develop, it is necessary to exercise proper control over costs during the construction phase. This requires scientific management strategies as well as managers with high professional competence; neither of these elements can be omitted. Managers actively learn advanced technical knowledge, thereby enabling the company to improve its economic efficiency while controlling costs.
