Construction cost control measures for standard steel structure space frame workshop project
1 Project Overview
Under the background of good social and economic development, the equipment manufacturing industry has also been upgraded, and gradually has the characteristics of large-scale and standardized. Industrial workshops are a necessary place to manufacture such equipment. In order to adapt to the development of the industry, it is also necessary to move towards standardization. According to the characteristics of the existing technology, the standard steel structure space frame workshop has become the main application form of industrial workshops because of its strong practicability, low cost, and high construction efficiency.
The project described in the article is the Nujiang Green Spice Industrial Park, which is located in the Wanqiao River Basin of Changjiang Town, Lushui City, Nujiang Prefecture. A total of 5 standard steel structure space frame workshops have been designed in this project, and 4 drawings have been issued at this stage. According to the design plan, the 1# workshop has 3 floors above ground and the height of the first floor is 9m;2–4# workshops are 4-storey above ground, the first floor is 6m high. In addition, the rest of the standard floors are set to 4.2m, with a total construction area of 10200m2, all in the form of space frames.2 Cost control objectives of each construction stage of standard steel structure space frame workshop
2.1 space frame cost control objectives in the preparation and design stage
After entering the 21st century, my country’s industrialization construction field has achieved good development, the scale of construction has continued to expand, and at the same time, it has brought about a market development situation in which material prices continue to rise. As a large-scale assembly manufacturer, it must create product advantages, at the same time reduce production costs as much as possible, and continuously introduce new technologies in the industry to create a more considerable production capacity. The expansion of production capacity involves a lot of work, among which the construction of new plants plays a decisive role. The investment in this aspect is relatively large. It is particularly critical to control quality and cost based on reasonable measures. According to the development of the industry, the use of space frame form has a better application effect. In order to minimize the cost of plant construction space frame, enterprises must form an accurate understanding of the standard steel structure space frame plant to achieve the effect of cost minimization.
The construction of a standard steel structure space truss workshop is systematic. In the preparatory work, in order to realize the in-depth refinement of the cost control plan, the cost estimate should be determined from each subdivision link such as beam and column processing and bracket installation. When creating a design scheme, the requirements of construction quality and cost of each division should be taken into account.
Make a reasonable choice after a multi-dimensional comparison, and do a good job of controlling the cost of the space frame in the preparation stage. From the point of view of construction materials, standard steel structure space frame workshops have a large demand in steel, concrete and other types of materials. In the preparation stage, it is necessary to combine the market conditions of such production factors to form a scientific evaluation plan, and put forward a scientific evaluation plan. Feasible cost control objectives, as the basic guide for the construction of standard steel structure space frame workshops.
2.2 Cost control objectives in the construction phase
Cost targets are set based on actual conditions during the construction phase, and this work is closely related to actual costs. In order to improve the purpose of cost control of the space frame, it is required to fully combine various cost-related factors in the design target, such as labor costs, material costs, equipment depreciation costs, etc. In-depth on-the-spot investigation to assess the feasibility of cost control objectives. According to the basic characteristics of the construction stage, the basic concept of increasing income and reducing expenditure should be implemented in the target planning work, and on the basis of the total target cost, it should be divided into multiple subdivided targets, corresponding to the bidding work of each branch, and the bidding control should be determined. price. In actual construction, a professional subcontracting team was selected to apply BIM to carry out modeling and in-depth design of standard steel structure space frame workshops. During the production of steel structure space frame frames, the material and materials of steel were optimized to reduce losses and thus save costs. At the same time, the management work is implemented into each budget revenue and expenditure, and the accounting mechanism is strictly implemented. In this way, the standardization of the construction cost control of standard steel structure workshops is improved, so as to form a close relationship with the construction team, so as to provide reliable and reliable expenditure control work. in accordance with. 2.3 Cost control objectives in the operation and maintenance phase
Different from the cost control target in the construction stage, in order to effectively achieve the cost target of the factory building in the operation stage, it is particularly critical to strengthening the cost management of maintenance, which is embodied in the maintenance of various components of the factory building and the stable operation of joist brackets. . In order to improve the feasibility of the cost target in the operation stage, the actual use environment of the plant should be fully considered in the planning work, such as plant load, environment, etc., and the impact of high temperature, high dust and other factors on the components should be taken into account, and the cost control target should be required. Planners go deep into reality and create cost control targets that are commensurate with plant maintenance needs.
3 Plant project construction cost control plan
3.1 Cost control in scheme design
Project construction needs to be guided by systematic planning. Through the project design scheme, specific planning and practical operation rules can be clarified, which is the key to good cost control. The characteristic of the design stage is that it has the function of linking the previous and the next. From the perspective of the construction process of the standard steel structure space frame workshop, it can be divided into four parts: evaluation, decision-making, design and implementation of the project. For a certain project, after the project is established, the pre-delineated vision can be transformed into an engineering entity through the design scheme, and the design also has the ability to guide the actual construction. In engineering design, there should be specific design standards for each scheme or even a detail. Whether it is the selection of raw materials or the configuration of construction equipment, it is directly related to the investment cost of the project. In a sense, the design stage not only clearly explains the construction standards, but also directly affects the investment scale of the plant.
The functionality of the standard steel structure space frame workshop is the primary goal, and the formulation of the design scheme should be based on the use function, and then take into account the cost control goal. Based on the method of design bidding, qualified design units can be selected to complete the design of the workshop. In the same plant project, with the change of the design unit, the resulting design plans are also different, and their performances in terms of safety and economy are different, which is greatly related to the professional quality and subjective preferences of the designers. related, and even the same design unit will propose different design schemes in different time periods. But in any case, as a high-quality design solution, it must be fully functional and safe to use as the basic premise, and meet the economic requirements as much as possible.
3.2 Cost Control in Drawing Design
Construction drawings are the basic guidance for engineering construction, and the same is true for the construction of standard steel structure space frame workshops. In order to reduce construction costs as much as possible, it is necessary to flexibly incorporate cost control concepts into design drawings. According to the overall construction requirements, the design of construction drawings must be based on the premise of not affecting the normal use of the workshop, and on this basis, the cost control requirements should be met as much as possible, and the amount of engineering materials such as steel frame and concrete should be appropriately reduced. In addition, considering the requirement of cost minimization, when conditions permit, the amount of brackets can be appropriately increased, and the number of pillar structures can be reduced. In this way, the amount of work at the level crossing can be controlled, the construction efficiency can be improved, and the cost can be effectively reduced. The patented product of the truss floor deck should be used as much as possible, so as to reduce the erection of the formwork frame and the binding of steel bars in the later construction, improve the construction efficiency, and save the construction cost. 3.3 Cost control in construction
In all aspects of the standard steel structure space frame workshop project, the construction stage has the largest cost demand, so the construction status at this stage will directly affect the cost control effect. According to the characteristics of plant construction, cost control can be implemented from the perspectives of personnel allocation and material selection. Regarding the control of labor costs, two groups of temporary workers and regular workers should be taken into account, and their reasonable distribution ratios should be determined. At the same time, the amount of wages of employees should be clarified, so as to improve the orderliness of employees’ operations, improve construction efficiency as much as possible, and avoid labor costs. cost unnecessary. Regarding the cost control of materials, the amount of steel used in the construction of standard steel structure space frame workshops is the largest. It is necessary to start from the two perspectives of purchase quantity and unit price, choose the appropriate measurement method of building materials, adopt scientific management methods, follow the quantitative distribution and The basic principle of access, with the prescribed limit as
Benchmark, implement the batch release system, provide material support for actual construction needs, and avoid material waste. Regarding the control of material price and cost, in addition to the purchase price, the costs caused by transportation and loss should also be considered. To achieve effective control of material costs.
After the standard steel structure space frame workshop is completed, it is still necessary to continue to do a good job in cost control. The operation object of this link is the various costs generated in the construction of the steel structure space frame, and the actual cost consumption can be accurately grasped by means of accounting and analysis. Compare and analyze it with the expected cost to clarify the deviation between the two. According to the analysis results, if there is a big difference between the actual cost and the expected cost, it is necessary to lock the problematic links, analyze the specific reasons in depth, and learn from it, so as to provide experience guidance for the future cost control in the field of plant construction, and continuously improve the cost control level.
4 Financial cost control of standard steel structure space frame workshop project In the field of engineering construction, financial statements are important production materials, which can be regarded as the final form of financial cost control and management. In the standard steel structure workshop construction project, in order to improve the quality of financial cost management, it is necessary to start with the construction cost, create a set of cost model for it, and obtain the cost investment coefficient and specific scale after calculation。
