At this stage, the competition in the air-conditioning installation engineering market is intensifying. Quality, service and price have become the rules for many mechanical and electrical industries to survive. The price of air-conditioning installation projects is particularly hot, and the electromechanical installation company is facing the trend of lowering costs for development. In other words, companies need to find a new way to manage the air-conditioning installation project, replace the relatively extensive and backward management mode, and optimize the people, materials, machines and tubes of the air-conditioning installation project.


1. The composition of the project cost


There are many aspects that affect the cost of air-conditioning installation projects. First, we must understand the composition of the project cost. From the component, the project cost is composed of labor costs, material fees, machinery fees, enterprise management fees, profits, taxes, and fees. Labor, material, machinery and enterprise management fees are always settled according to the sub-projects; taxes and fees are subject to national requirements and cannot be changed; profits are the most important considerations for enterprises, so the total price must be In the case of the need to ensure profit margins, reasonable measures must be taken to reduce project costs (people, materials, machines, and management).


2. Influencing factors and improvement measures of project cost


(1) Material cost


Material cost is an important part of the total cost of air-conditioning installation engineering, accounting for a large proportion. In an installation project, there are many types of materials to be used, and different materials are available in various models and specifications, and the prices are naturally different. Therefore, it is important to understand the materials and select the appropriate materials, and some construction materials can be replaced with each other. It is recommended that the air-conditioning installation engineering construction enterprises conduct research on the local building materials market before construction, fully grasp the market conditions, and also find suitable long-term Partners, it is best to use the Internet to build their own materials & price database; use the Internet for big data management, so that you can grasp the performance of new technology and new materials in the first time, select the most suitable materials in engineering construction, not only It can save costs, improve work efficiency, and reduce labor costs in the material procurement process, thus significantly reducing material costs.


(2) Labor costs


  In the process of air-conditioning installation, labor costs and material costs account for a large proportion. Labor costs mainly depend on local labor quotas (reflecting the labor efficiency of production workers under normal construction conditions), generally have a relatively normal reference price. Or salary level, therefore, to save labor costs, you can only improve the manual quota by improving the process, management, and training, so that workers can do more work in the same time, resulting in greater benefit. Saving labor costs depends to a certain extent on the improvement of management level and technical level.


(3) Quality of engineering design plan


It is well known that the whole life cycle of an air-conditioning installation project consists of the project decision-making phase, the project implementation phase and the project use phase; the engineering design phase belongs to the preliminary work of the project engineering implementation phase, and the design plan serves as a guiding role for the project as a construction budget. With the reference of actual construction, a reasonable design scheme can effectively avoid construction blind spots, which is an important means to improve the level of engineering installation and construction and reduce engineering costs.


The quality of an air-conditioning installation engineering design mainly depends on whether the technical design meets the basic functional requirements, whether it meets the requirements of national or industry standards, and whether the design and construction drawings can directly guide the construction, regardless of the feasibility analysis or the later stage. In the design drawing of the construction drawing, the design level of the designer directly affects the overall design effect, which leads to the differentiation of the project cost. Therefore, choose a responsible one. The technical strength is solid, and experienced designers are especially important in project engineering. Excellent design engineers are no less effective than a good project manager.


So what can we do in reality? Based on years of experience, here are some suggestions:


(1) Fully understand the air conditioning installation project before design, including the project demand, use time, local energy price, whether there is a peak valley electricity price, etc., and the opportunity must go to the project site to conduct on-site investigation;


(2) There must be a reviewer at the time of design, and the auditor should conduct multiple rounds of inspection to avoid low-level problems.


(4) Multi-engineering cross-construction management


Due to the increasing scale of the current electromechanical air-conditioning installation projects, the construction of a project is not only a separate installation of air-conditioning, but often with other projects, such as fire, strong and weak, fire, etc. During the construction process, there are often different types of work that cross each other, such as the conflict between the location of electrical pipelines and water pipes and air ducts. Which side will retreat? If there is no clear stipulation before, it will cause different efforts. Everyone will quickly construct and seize the opportunity. Whoever is the first place to work will eventually lead to other constructions failing to work smoothly, but the construction site will not be beautiful. Cause engineering changes, extended construction time, etc., thereby increasing construction costs. Air conditioning installation project


Therefore, (1) requires each construction team to carefully check the intersection of the drawings in the preliminary design process. Before the construction, it is necessary to open the preliminary meeting, clarify the various duty sites, and increase mutual understanding between the various types of work;


(2) The construction process should design a director and general project leader to ensure the normal construction of the project, and at the same time effectively control the construction materials, strengthen the management of construction materials, and strive to reduce the non-essential consumption of construction materials, thereby reducing the total cost of production. .


(5) Using mature and stable processes


The upgrading of new processes can promote the management of the project to a certain extent, but at the same time, it is necessary to fully understand and understand the use requirements and products. Before the construction, the processes and technologies that may be used in product design are communicated in advance to improve effectiveness. Otherwise, there will be a certain risk of instability when trying new products. In order to avoid rework caused by process instability, I suggest that a comprehensive plan should be made according to requirements before construction, and the new process should be verified repeatedly. To ensure the feasibility of advanced processes. At the same time, it is recommended to select processes with relatively mature technology and high operational stability to ensure the smooth implementation of new air conditioning installation engineering processes.

(6) Strengthen daily data management and control completion settlement


In order to better improve the cost control effect of air-conditioning installation projects, while ensuring reasonable design and personnel management, we should also pay attention to the staged acceptance and preservation of data files during the project process. In other words, various design changes during the construction process. The construction site visa, the project concealed construction acceptance record and the equipment related quality acceptance data are sorted and preserved, and at the same time, two documents of electronic paper are stored; thus, the project can be checked one by one according to the construction process when the project is completed and accepted. Missing and miscalculation, and repeated calculations to ensure the effectiveness of air-conditioning installation engineering cost control.


3. Conclusion


To sum up, in the increasingly competitive market development trend, enterprises must work hard on cost and cost control in order to obtain a greater competitive advantage in air-conditioning installation engineering. Strengthen the management of each stage, and rationally select construction materials and construction techniques, do a good job in design planning and construction quality control, which is the skill that enterprises must master at present. According to their own experience, the relevant factors affecting the price of air-conditioning installation projects and commonly used The measures are as described above, hoping to help everyone.
