Construction project management and project cost control

Thread Content

Organize efficient construction by optimizing the combination and rational allocation of production factors, ensuring balanced construction progress, and utilize modern management techniques and methods to achieve project objectives and enable the company to obtain good overall benefits. Construction project management is the comprehensive planning, organization, control, and coordination carried out to ensure that a project meets the required quality standards, adheres to the specified time limits, and stays within the approved budget. The object of project management is the project, and since projects are one-time initiatives, project management requires the application of systems engineering concepts, theories, and methods to ensure it is comprehensive, scientific, and systematic. The goal of project management is the goal of the project itself. This goal defines the main aspects of project management as \"three controls, two managements, and one coordination\", namely schedule control, quality control, cost control, contract management, information management, and organizational coordination. The production factors of construction projects include labor, materials, mechanical equipment, technology, and capital. These factors are interrelated, purposeful, and adaptable to their environment; they form a complex, multi-dimensional relationship with one another. This indicates that construction is a systematic process, and project management in construction possesses the characteristics of systematic management. To strengthen construction project management, it is necessary to conduct a detailed analysis of the production factors involved in such projects, and to carefully study and enhance their management. The management of the production factors in construction projects mainly manifests in four aspects: (1) Optimizing the allocation of production factors, that is, providing or investing these factors in a timely, appropriate quantity, at the right proportions, and in the suitable locations to meet the needs of construction work ； (2)&127; Optimize the combination of production factors, that is, appropriately mix the factors invested in construction projects so that they can function in coordination during construction ； (3)&127; Conduct dynamic management of production factors. Dynamic management is a means and guarantee for optimizing allocation and optimization of combinations. Its core aspect involves effectively planning, organizing, coordinating, and controlling various production factors in accordance with the inherent laws of a project, so that they can flow reasonably within the project and balance can be achieved through dynamic adjustments ； (4)&127; Make rational and efficient use of resources in order to enhance the overall effectiveness of project management and promote overall optimization. II. The construction system of project management The construction system of project management comprises three sub-systems: technical, social, and economic. These three represent different aspects of the construction project system, and they are closely related to one another, interacting and influencing each other. (1)&127; Technical system. The technical system is the core of the three subsystems, as the ultimate goal of construction project management is to deliver high-quality engineering products at low costs to the owner. Construction activities are fundamentally technical in nature; only by adopting advanced technical measures can it be possible to achieve high output with low input, while also producing high-quality products. Determining scientific and reasonable construction plans and techniques is an important aspect of the technical system. (2)&127; Social system. Construction projects are carried out by people, which inevitably leads to interactions between them, thus forming a social system. In project management, people are the most important factor. The project manager, who is the primary person responsible for a construction project, must possess high moral standards, comprehensive knowledge of construction techniques, and strong organizational and leadership skills. The key to determining the level of these leadership abilities lies in the ability to fully motivate the workforce, which is also essential for achieving the project’s goals successfully. (3) Economic system. The economic system is a key subsystem of the project management and construction system, and it is one of the “objective subsystems”. Engineering construction is a process of productive activity, as well as an economic activity. Construction projects inevitably require the investment of labor, materials, machinery, and funds; excessive investment leads to waste, while insufficient investment affects the construction schedule and project quality. The economic system emerges alongside the technical and social systems; it is a system of inputs and outputs. In every stage of the construction process, an analysis of the costs involved must be carried out, and responsible cost management should be implemented. All resource elements need to be dynamically optimized and combined in accordance with a set timeline, so as to achieve the highest possible output with the lowest possible costs. In other words, project cost control must be applied at each stage of the construction process; the cost accounting process must proceed in tandem with the construction activities, keeping pace with them. Only in this way can the accuracy and consistency of project cost accounting be ensured, and true project cost control can be achieved. Project cost control refers to the process of guiding, supervising, regulating, and restricting the human resources, material resources, and expenses incurred in production and operations during the formation of project costs. It involves correcting any deviations that may occur or have already occurred in a timely manner, so as to keep all production costs within the planned range and ensure the achievement of cost targets. The purpose of cost control in construction projects is to reduce project costs and improve economic efficiency. I. Principles of project cost control The principles of cost control in construction projects form the basis and core of enterprise cost management. When managing costs during the construction process, the project management team must adhere to the following basic principles. (1) The principle of cost minimization. The fundamental purpose of cost control in construction projects is to use various cost management techniques to continuously reduce the costs of these projects, thereby achieving the goal of reaching the lowest possible cost level. When applying the principle of cost minimization, attention should be paid to the possibilities of reducing costs and achieving reasonable cost minimization. On the one hand, explore various ways to reduce costs, turning possibilities into reality ； On the other hand, it is necessary to proceed from reality and establish a reasonable minimum cost level that can be achieved through subjective efforts. (II) Principle of comprehensive cost control. Total cost management is a form of management that covers the entire enterprise, all its employees, and the whole process; it is also known as \"three-total\" management. The comprehensive control of project costs involves systematic and substantive elements, including the responsibility framework of various departments and units as well as economic accounting at the team level. It is necessary to ensure that cost control is everyone’s responsibility, without anyone being exempt from it. The full-process control of project costs requires that cost control efforts be carried out continuously throughout all stages of the project’s construction; there should be no gaps in this process, nor should the intensity of control vary from time to time. The costs of the construction project must remain under effective control from start to finish. (III) Principle of dynamic control. Construction projects are one-time events, and cost control should focus on intermediate control during the project, that is, dynamic control. This is because cost control in the preparation phase of construction merely involves determining cost targets based on the specifics of the construction plan, preparing cost budgets, and formulating cost control strategies, in order to lay the foundation for future cost control ； Cost control during the completion phase is challenging, as the cost gains and losses have largely been determined; even if discrepancies arise, it is too late to make corrections. (IV) Principles of goal management. The contents of goal management include: the setting and breakdown of goals, assigning responsibilities for achieving those goals and carrying out their implementation, checking the results of goal implementation, evaluating the goals and making adjustments to them. This creates a cycle of planning, implementation, checking, and action in goal management, namely the PDCA cycle. (5) The principle of combining responsibilities, powers, and interests. During the project construction process, while assuming responsibility for cost control, the various departments and teams under the project management office also have the authority to carry out cost control. Meanwhile, the project manager is responsible for regularly reviewing and evaluating the performance of these departments and teams in terms of cost control, implementing rewards and penalties accordingly. Only by truly implementing cost control that integrates responsibilities, powers, and interests can the desired results be achieved. II. Project cost control measures: The ways to reduce the costs of construction projects involve increasing revenue while simultaneously cutting expenses, or in other words, boosting income alongside cost savings. Either only focusing on opening up sources without cutting costs, or only focusing on cutting costs without opening up sources, will not lead to cost reduction; at the very least, it will not achieve an ideal level of cost reduction. The measures to control project costs can be summarized into three main aspects: organizational measures, technical measures, and economic measures. (1) Organizational measures. The project manager is the primary person responsible for project cost management, overseeing all aspects of cost control within the project team. They must keep track of and analyze profit and loss situations in a timely manner, and take effective actions promptly ； The Engineering and Technology Department is responsible for the construction techniques and progress of the entire project. It should employ advanced technologies wherever possible, while ensuring quality and completing tasks on schedule, in order to reduce project costs ； The Operations Department is responsible for the implementation and management of contracts, handles the submission of requests for payment related to project progress, and deals with matters related to construction compensation. The Finance Department should focus on strengthening contract budget management in order to increase budgetary revenues from projects ； The head of the finance department is responsible for the financial aspects of engineering projects; they must constantly analyze the project’s financial inflows and outflows and allocate funds appropriately ； Other departments and teams within the project management office should be organized carefully, fulfilling their duties to increase revenue and reduce expenses. (II) Technical measures 1. Develop advanced and economically reasonable construction plans to achieve the goals of shortening project duration, improving quality, and reducing costs. The construction plan includes four main components: the determination of construction methods, the selection of construction equipment, the arrangement of construction sequence, and the organization of flow construction. Choosing the right construction plan is key to reducing costs. 2. During the construction process, strive to find various new processes, technologies, and materials that can reduce consumption and improve work efficiency, as well as other technical measures to cut costs. 3. Strictly control quality, eliminate the need for rework, shorten inspection times, and save costs. (III) Economic measures 1. Control and management of labor costs. It is mainly to improve labor organization and reduce wasted idle time ； Implement a reasonable reward and punishment system ； Strengthen technical education and training ； Strengthen labor discipline, reduce non-production and auxiliary staff, and strictly control the proportion of non-production personnel. 2. Control and management of material costs. The main focus is on improving the processes related to the procurement, transportation, receipt, and storage of materials, in order to reduce losses at each stage and save on procurement costs ； Stack site materials properly to avoid and minimize secondary handling ； Strict inspection of materials upon arrival and a system for limited material issuance ； Formulate and implement technical measures to save materials, use them reasonably, and make comprehensive use of all resources. 3. Control and management of machinery costs. It mainly involves the proper selection and rational use of mechanical equipment, as well as proper maintenance and repair of such equipment, in order to improve their condition, utilization rate, and efficiency. This helps to accelerate construction progress, increase output, and reduce the costs associated with using machinery. 4. Control of overhead costs and other direct costs. &127; mainly by streamlining management structures, determining appropriate management spans and levels, and saving on construction management costs, etc. The organizational, technical, and economic measures for project cost control are integrated and interact with one another. The Project Manager’s department serves as the center for project cost control. Based on the bid price, it sets objectives for cost control. All departments and teams work together to establish a project cost control system that involves economic optimization of construction plans, material procurement, labor allocation, all of which are based on the market bid prices. Based on the above analysis, construction project management and project cost control are complementary to each other; only by strengthening construction project management can project costs be controlled ； Only by achieving the goal of project cost control does it make sense to strengthen construction project management. Cost control in construction projects reflects the essential characteristics of construction project management and represents its core content. Cost control in construction projects serves as an objective and fair criterion for evaluating the performance of construction project management.
