Introduction
The construction industry has achieved unprecedented development with the rapid development of the global economy and society. Building materials are the basis of construction projects, and they account for a large proportion of the investment in the entire construction project, which has an important impact on the cost of the entire construction project. In recent years, as global environmental problems have become increasingly prominent, people's awareness of environmental protection has gradually increased, and the concept of green buildings has become popular. The purchase cost of environmentally friendly materials may be higher than that of traditional materials, so people think applying new green non-metallic fiber will inevitably lead to an increase in construction costs, which also implements the green building concept encounter specific resistance. Compared with traditional building materials, the application of new green non-metallic fiber will inevitably lead to a series of changes in the budget of construction projects. Therefore, it is necessary to study the impact of new green non-metallic fiber on construction cost management. Meticulous research is to improve the efficiency and quality of construction project cost management, promote the broad application of new green non-metallic fiber in construction projects, and realize the sustainable development of construction engineering enterprises. This paper analyzes the impact of new green non-metallic fiber on the cost management of construction projects to facilitate the creation of a green development model for the construction industry. On the one hand, it can lay a social foundation for the new regular economy. On the other hand, it is in order to realize the engineering cost control of construction projects and lay the economic foundation for the sustainable development of the construction industry.
Literature review
The current era is an era of rapid economic development. The competition trend of every industry is intensifying, and the construction industry is also facing more significant difficulties and challenges because the original construction technology does not conform to the current social trend, people The requirements for living standards are raised, and the requirements for construction engineering technology and quality are n getting higher and higher. Therefore, the construction
g industry must adapt to the new environment and meet
n future technical challenges with a modern attitude. In
the process of construction, Project cost management will seriously affect the economic benefits of the
enterprise. The impact of technology application under the traditional construction mode on the enterprise is unfavorable. Particular attention should be paid to new building materials, and modern information technology tools should be used to strengthen construction and construction management.
Huang Xiangui pointed out that new building materials are produced with the development of science and technology and improving people's environmental protection awareness. From the engineering design perspective, project cost management is more in line with the requirements of construction projects, and the wide application of new building materials in construction projects is promoted [1]. Zhang Yanfei, Zhang Hanbo In the cost management process, materials are a crucial link. Traditional materials have many defects in function and quality, which will seriously affect the quality and service life of the building. The emergence of new materials effectively solves these problems and saves energy, protects the environment, and saves costs[2 ]. Mei Zaokang stated in his research on the application of new materials to cost management that compared with traditional building materials, new building materials in the construction field include metal and non-metal materials, chemical materials, natural building materials, and other materials. Using the above-mentioned new materials. It should be possible to significantly optimize the overall quality of the building at the root and, at the same time, improve the overall architectural effect. Under the current situation, the construction industry is showing a transformation trend, and the critical root cause is the birth of various new building materials. At the same time, the new building materials have better thermal insulation properties, lightweight properties, aesthetics, and energy-saving properties. They can significantly improve the overall strength of the building materials themselves. New building materials are gradually replacing traditional building materials, thereby fully optimizing the environmental protection and ecological benefits of buildings and demonstrating a higher level of humanistic taste and atmosphere. Therefore, new building materials fundamentally meet the higher-level aesthetic needs of urban and rural people and can optimize and improve the quality of comprehensive building construction [3].
New green non-metallic fiber refers to improving the performance of building materials or recycling waste materials in production and life based on traditional building materials through the innovation and application of new processes and technologies. A new building material derived from Energy saving, environmental protection, pollution-free, non-toxic, non-radioactive, and recyclable is the main feature of new green non-metallic fiber. With the popularization and promotion,there are more and more new green non-metallic fiber types with rich functions, such as environmental protection wall materials, floor materials, and decoration materials. These green environmental protection Building materials are involved in all aspects of construction projects, which will not only reduce construction waste and avoid environmental pollution but also some materials can be recycled and reused,
which reduces construction costs to a certain extent and promotes the green and sustainable development of the construction industry[4 ]. From the project cost perspective, building materials are essential to specific management costs. Therefore, effectively improving the cost management of building materials is an efficient measure to ensure the cost management of construction projects. The important feature of green building materials is environmental protection and energy saving. It is a new type of ecological building material. Under the background of ensuring the quality of construction projects, the application of green building materials can not only reduce resource consumption but also reduce production costs. Project cost management has positive economic significance [5]. Wang Lingling said that the key point of construction project cost management lies in building materials, which are a key link affecting costs, so strengthening the cost and cost management of building materials is an effective measure for total project cost management and non-metal fiber new green environmental protection building materials are a kind of Energy-saving and recyclable green environmental protection products not only meet the requirements of construction technology, increase turnover times, save wood resources, but also reduce the investment of construction enterprises and greatly reduce construction costs. New energy sources need to be developed in today's construction industry[6]. To sum up, new green non-metallic fiber cannot only effectively solve the pollution problem in the construction industry but also reduce project cost management, bring more economic benefits to construction, and promote the harmonious development of green and low-carbon construction industry.
The significance of the application and promotion of green non-metallic file
With the implementation of energy saving and emission reduction and the concept of green and environmentally friendly production, it is required to achieve energy-saving development and optimize the application of various resources in the development of various industries. As far as construction engineering is concerned, the waste of various resources and equipment and the low efficiency of installation projects are the key points that require construction projects to achieve reform, innovation, and development under the new situation. In the construction industry, the promotion and application of new green non-metallic fiber has obvious significance.
1. Able to achieve ecological benefits of environmental protection. From the design of green non-metallic fiber to decoration materials, and dark materials, the raw materials and production processes of these materials are recyclable, which reduces the consumption of resources and energy. At the same time, the advanced and scientific applications of new green non-metallic fiber can avoid environmental pollution caused by the accumulation of waste resources and present the misplaced treasures in a different form, thereby protecting the environment.

2. The economic benefits of cost saving can be achieved. Compared with traditional construction projects, using new green non-metallic fiber can save energy and reduce emissions for engineering projects by optimizing construction technology. For example, applying new green non-metallic fiber in construction and installation projects can improve the heat preservation and sound insulation, and noise reduction effects of buildings. This significantly reduces the resource consumption in the post-construction project. At the same time, the production and development of some energy-saving and environmentally friendly non-metallic fiber building materials have been paid more and more attention by society. At present, relevant national governments have also proposed various support measures and the cheap performance of non-metallic fiber materials themselves has promoted The production cost of green and environment-friendly building materials significantly reduced, thereby reducing the cost of the entire construction project and bringing economic benefits to the construction project.
3. The social benefits of quality and safety can be achieved. The key to a construction project is to improve the project's quality and safety and prolong the construction project's service life. To realize the application and promotion of non-metallic fiber green and environmentally friendly building materials, it has advantages in terms of technology and technology, excellent performance, and more substantial safety and environmental protection performance, which can improve the comfort of indoor living and meet the needs of more and more residents. Need. For example, the existing construction projects have the characteristics of intelligence and informatization [7].
Unique advantages and characteristics of new building materials
New non-metallic fiber building materials are built on the premise of traditional building materials and incorporate many new features. This is because many new materials used in the construction field have better aesthetics and environmental protection effects, and the total energy consumed by buildings in various time periods can be fully reduced. At the same time, the new non-metallic fiber materials also have excellent ecological and environmental protection properties. If they can be used comprehensively, it will significantly reduce energy consumption in the current construction field. Specifically, new building materials have the following advantages and characteristics:
The first is environmental protection. Under the current situation, all kinds of building materials used in building construction have diversified basic characteristics, which are objectively beneficial to significantly improving the original living standards of urban and rural residents and can also comprehensively beautify the entire living environment. However, at the same time, the total amount of energy consumed by certain building materials is showing a significant increase, and the corresponding construction pollution is also serious. Suppose the above-mentioned status quo is not changed from the source. In that case, it is likely to be detrimental to health, and it will also bring
prominent pollution to the local surrounding ecology. Therefore, new building materials with environmental protection features are more beneficial to maintain the cleanliness of the environment and realize all-around environmental protection and energy saving according to the basic idea of adapting measures to local conditions.
The second is greenness. New non-metallic environmental protection building materials have obvious green characteristics, the key of which is the energy-saving properties of building materials. In contrast, new building materials can significantly reduce all kinds of energy consumed in the construction field, so it reflects the best energy-saving purpose and goal. Fundamentally, the construction industry is manifested in the typical characteristics of greater resource consumption, higher pollution, and greater energy consumption. Therefore, the environmental load involved in it can be fully reduced. Under this premise, better colocalization is highlighted. Aims and objectives.
The last is contemporary. In the field of traditional architecture, typical building materials mainly include clay-sintered bricks, concrete, and other materials. According to literature surveys, traditional building materials account for more than 80% of the construction field [8]. Therefore, the current construction field shows a trend of higher energy consumption, so it is urgent to use comprehensive measures and means to limit excessive energy consumption. In recent years, most enterprises have fully realized the value and significance of using new non-metallic fiber building materials, so they are also exploring new models of building environmental protection that is applicable to them. Therefore, it can be seen that the series of building materials developed by the new non-metallic fiber itself reflect the excellent contemporary and environmental protection value, which can adequately replace some traditional building materials, and the types of building materials with relatively high energy consumption must be fully restricted.
The impact of non-metallic green and environmentally friendly building materials on the cost management of construction projects
Construction cost management is an important economic indicator to measure a construction project. For construction material management and construction cost management, traditional construction models and methods will save many construction materials, and it is not conducive for construction enterprises to do a good job in construction cost management. Accounting, due to a large amount of engineering involved in construction projects, the application factors affecting the cost control measures also spread to various subjective and objective factors. During construction projects, construction enterprises are very important to the construction materials management of construction sites. , because the funds spent by enterprises to purchase construction materials are a very large expenditure for construction projects. If the construction materials can be controlled within a reasonable range, it will save many construction costs for construction enterprises. Especially after the
emergence of new non-metal fiber building materials, the new non-metal fiber building materials will help enterprises to calculate the consumption of building materials more scientifically and effectively, which will bring better economic benefits to enterprises and better promote the development of the construction industry develop. In particular, the application and development of non-metallic fiber green environmental protection materials in construction projects have brought about a huge impact on the economic benefits of construction projects. Therefore, project cost management directly affects the survival and development of an enterprise and the quality of a construction project. Therefore, the impact of new non-metallic fiber materials on construction project cost management is mainly reflected in the following two aspects.
Impact on construction cost
Currently, there are more and more new non-metallic fiber green and environmentally friendly building materials in the construction market. Some of the new non-metallic fiber environmentally friendly building materials themselves are relatively high in cost. For example, although nanofiber materials have better performance, their cost value is too high. High, in actual engineering construction, such new non-metal fiber green environmental protection building materials will bring a certain increase to the total project cost, which is why many construction projects are unwilling to use too many new non-metal fiber green environmental protection buildings. One of the main reasons for the material.
With the promotion and implementation of green building concepts in the construction field, the market for green building materials has gradually grown, and non-metallic fiber green building materials have been vigorously put into development and use; however, some non-metallic fibers cannot meet the degradable and renewable conditions ( For example glass fiber, carbon fiber), or cannot reach high mechanical properties (for example straw fiber, straw fiber), and the various technologies are not yet mature, and the performance of the production product is not stable enough, resulting in the application of green and environmentally friendly building materials. Smaller. However, with the rapid development of modern technology in the world and the popularization of green buildings in construction projects, the market demand for green non-metal fiber environmental protection building materials is gradually increasing, and green environmental protection building materials have gradually formed a batch and integrated production and manufacturing model. , to promote the gradual reduction of the production cost of green environmental protection non-metallic fiber building materials, and the green environmental protection non-metallic fiber building materials are simple in technology, high in strength, energy-saving and material-saving in the construction process, so the project cost of construction engineering enterprises Management and control are more beneficial.
Impact on project cost management mode
In the process of project cost calculation, project cost management personnel need to classify various materials and fill in various forms to calculate the amount and cost of materials. However, with the continuous emergence of various new types of non-metallic fiber green and environmentally friendly building materials, the varieties, specifications, models, and recording methods of various materials have undergone major changes compared with traditional building materials. The model cannot be applied to new non-metallic fiber green and environmentally friendly building materials, which increases the difficulty of project cost management, increases the workload of project cost management, reduces the work efficiency of project cost management, and is not conducive to the smooth development of construction projects. In addition to the cost control of materials, it is also necessary to manage the project cost of labor and mechanical equipment. However, due to the use of new non-metallic fiber green and environmentally friendly building materials, there are new requirements in terms of construction methods, construction techniques, and construction machinery and equipment. Project cost management personnel cannot accurately calculate labor costs and mechanical shift fees based on past work experience, which increases the difficulty of project cost management.
Response to the impact of new non-metallic fiber green and environmentally friendly building materials on construction project cost management
For the cost of construction projects the application of new non-metallic fiber green and environmentally friendly building materials will have a positive impact on it and will also indirectly reduce the cost of construction projects. However, many types of new green non-metallic fiber environmental protection building materials exist. A little carelessness in the use of materials will increase the construction cost, so a reasonable solution to the application of new building materials in construction is the top priority.
Suggestions to solve the impact of supply and price fluctuations of new non-metallic fiber green building materials on project cost management
In recent years, the market of new non-metallic fiber green environmental protection building materials has developed rapidly. There are many varieties, specifications, and models of materials, and there are also large differences in quality and price. During the period, the prices of new non-metallic fiber green and environmentally friendly building materials also fluctuated greatly. In traditional project cost management, empirical methods or manual collection methods are usually used to obtain relevant price and transportation information. However, the information obtained by this method may need to catch up and affect the accuracy of the project cost. In order to solve this problem, relevant departments or new non-metal fiber green environmental protection construction enterprises can jointly establish a project cost platform for new non-metal fiber green environmental protection building materials, provide the latest quotations and

transportation price information of building materials across the country, and make full use of data mining Technology, cloud computing technology, information technology, and other advanced technologies carefully analyze relevant product information and price information, screen out building materials that meet the quality requirements of construction projects, determine a reasonable price range, and apply them to construction project cost management. Make the cost of new non-metallic green and environmentally friendly building materials more accurate, and solve the impact of supply and price fluctuations of new non-metallic fiber green and environmentally friendly building materials on project cost management [9].
Strengthen the system construction of the application of new non-metal fiber green environmental protection building materials
At present, the construction industry still needs to form a unified and standardized implementation system and standard for the application of new non-metallic fiber green and environmentally friendly building materials. As a result, the actual cost of the new non-metallic fiber green building materials in the actual application process is quite different from the budgeted cost and estimated cost in the project cost. Therefore, strengthening the system construction of new non-metallic fiber green and environmentally friendly building materials to achieve institutionalized construction can create a good atmosphere for the application of new non-metallic fiber green and environmentally friendly building materials and ensure that the application of building materials can be promoted from a conscious level. The application of management and control measures, the guarantee of supervision and management from the system, to ensure that the entire cost management and control measures can be implemented in the entire process of the application, installation, and construction of new building materials, is the premise of the current problem that needs to be solved urgently.
Secondly, because the construction personnel and construction management personnel in the project construction process lack relevant cost control awareness, they are only responsible for completing the project construction tasks on time, in quality and quantity, and some new technologies are involved in the application of emerging building materials, method, the site often completes the construction project task by increasing the mechanical equipment, increasing the staff, etc., resulting in an increase in the cost of the construction project. Establishing a sound cost management system for new building materials engineering is very important. Based on a detailed analysis of all aspects of the construction site, it is necessary to clarify the engineering cost management responsibilities of each construction manager and team in the construction of the construction project. Clarifying the objectives of project cost management at different stages, developing detailed evaluation indicators for project cost management, regularly assessing each department's project cost management situation, and taking corresponding reward and punishment measures
can avoid inconsistent rights and responsibilities in the project cost management process. It can also mobilize the enthusiasm of relevant staff in project cost control and improve the efficiency of project cost management [10].
Finally, a refined management system for the application management of new non-metallic fiber green and environmentally friendly building materials is established, and the engineering cost management of building materials is incorporated into the entire project construction. In this way, in the construction and installation design budget, all rights and responsibilities can be clarified, a clear contractual relationship can be provided, and the construction and installation project can be "step by step" to control the economic cost in the existing project budget; it is also necessary to formulate a good construction plan. The cost management work system is applied to new engineering materials. For example, in construction, bidding for building materials needs to be standardized. This will directly affect the control results of the construction project design plan and project cost management. The construction of the entire construction material cost engineering management system can ensure that every aspect of material cost management can be practical and realistic[11].
Conclusion
The new non-metallic plant fiber green and environmentally friendly building materials have very obvious advantages of environmental protection and energy saving. From the current stage, construction projects are developing in the direction of green and low-carbon buildings. The application of materials can reduce energy consumption, thereby reducing energy cost consumption. Secondly, the application of new non-metallic fiber green and environmentally friendly building materials in construction projects is an inevitable trend in the future development of the construction industry. As the material basis of buildings, the application of new non-metallic fiber green and environmentally friendly building materials will inevitably put forward new requirements for the design, construction, and management of construction projects, and these changes will have varying degrees of impact on construction project cost management. These influences have both positive and negative factors. The construction project cost management level is directly related to the final economic benefits of the entire construction project. Therefore, relevant units and project cost management personnel must take corresponding measures to strengthen project cost management at each stage of construction projects and finally achieve the goal of project cost management. , to promote the green and sustainable development of the construction industry.
