In the field of construction, whether it is roads, bridges or tunnels, foundation treatment is a crucial part. It is not only related to the stability and safety of the whole project, but also directly affects the quality and service life of the project. Recently, I had the privilege of learning that a friend had signed a traffic engineering contract with China Construction Second Bureau, which included a detailed contract unit price for the foundation treatment part. These data are true and reliable, and undoubtedly have high reference value for peers in the industry. Below, let's dive into the contract unit price of these basic processing parts.
First of all, we see the unit price of digging trench earthwork, which is 22$5. This ** seems simple, but it actually contains many factors, such as the type of soil, the difficulty of excavation, the distance of transportation, etc. Therefore, this can be regarded as a measure of the technical level and work efficiency of the construction team.
Next is the backfill of the earth, which is 14 per cubic meter$5. The work of backfilling the earthwork mainly includes the steps of clearing the trench, filling the soil, compacting the soil, etc., which reflects the labor intensity of these jobs and the cost of materials required.
The unit price of sand cushion and gravel cushion is 152 yuan and 145 yuan per cubic meter, respectively. The main function of these two types of cushion is to improve the stability and bearing capacity of the foundation, and at the same time, it can effectively reduce soil erosion. The difference between these two ** may be related to the type of material used and the construction technique.
The unit prices of C15 concrete cushion and C20 concrete foundation are 512 yuan and 541 yuan per cubic meter, respectively. The main difference between these two types of concrete is its strength and durability, which is also reflected in its **. The C25Icon concrete foundation is 552 yuan per cubic meter, which may be due to its higher strength and better durability.
The unit price of foundation steel bars and embedded iron parts is 1,300 yuan and 6,300 yuan per ton respectively. These two materials are an indispensable part of the construction project, and their ** is directly related to the cost and quality of the project. The ** of the rebar is relatively low, probably because of the relatively simple production process;The ** of embedded iron parts is higher, probably because its production requires more refined processes and technologies.
In the end, what we see is the ** of sporadic concrete components, 571 yuan per cubic meter. This ** includes the cost of production and installation of precast concrete elements, reflecting the cost and value of precast concrete elements.
Overall, the contract unit price for these basic processing components provides us with a valuable insight into the value and cost of the basic processing work in traffic engineering. At the same time, these data also provide us with a reference to help us make more accurate judgments in the future project budget and **.
However, we also need to note that these unit prices are only part of the basic processing part, and the actual project cost also includes many other factors, such as design fees, supervision fees, construction machinery rental fees, etc. Therefore, when we apply this data in practice, we must consider a variety of factors holistically in order to make the most rational decisions.
Finally, I would like to emphasize that although these data are a specific case of China Construction Second Bureau, the principles and methods behind them are universal. No matter what region we are in or what type of project we are engaged in, we can get valuable inspiration and reference from it.
