Foreword: Focus on highway and municipal majors, and I am fortunate to be able to communicate with colleagues in the industry**! There is a road in the book mountain, and there is no end to the sea of learning, and I am willing to make a brick and build a road of engineering with everyone.
In the project, it is common to encounter the content of concrete structure or reinforced concrete structure that needs to be demolished, and although it is not difficult to consider the actual cost, it is easy to cause the cost to be missed or double-counted if it is not careful. Let's take a look at the measurement first. First of all, let's talk about what concrete or reinforced concrete structures will be considered for demolition, such as old and dangerous bridges and culverts, drainage protection structures that need to be rebuilt, etc., which may involve demolition.
For example, if a project is a dangerous bridge reconstruction project, it is necessary to dismantle all the original old bridges, and according to the 2018 list measurement rules issued by the ministry, concrete or reinforced concrete need to be considered separately for measurement. Its measurement subheadings are as follows:
The demolition of reinforced concrete structures usually appears in the demolition of structures such as bridges and culverts, and the demolition of concrete structures usually appears in the demolition of structural types such as drainage protection, and the content of its measurement is consistent: according to the location shown in the drawings, the original structure within the scope of the demolition subgrade is measured in cubic meters; And its work content is also the same:1excavation; 2.loading, unloading, and transfer handling; 3.The site is cleaned and leveled.
Let's take a look at how to consider the valuation, the demolition quota of the structure I personally think that the main consideration is to use the old building demolition quota, that is, the 4-11-17 category quota subheading. The demolition of old buildings is mainly the process of dismantling old buildings by means of manual, mechanical or blasting, etc., and cleaning up the site, and stacking the available materials, including removing the auxiliary components of the old building, prying out the masonry, chiseling or blasting to blast out the concrete, dismantling iron parts such as wood and steel bars, cleaning up the site and removing construction waste, and a whole pile of materials.
It should be noted that this quota comprehensively considers the on-site clean-up after demolition and the on-site clean-up of waste, on-site transportation and stacking, etc., and does not include the off-site transportation cost of waste. Although it is stipulated that the cost of off-site transportation of waste should be considered according to the earthwork transportation quota, it is recommended that the hardness of the waste after the demolition of the general building be matched with the stone transportation quota.
By extension, if the structure of the expressway is demolished, the demolition quota sub-item in the budget quota for highway reconstruction and expansion can be considered, which is more applicable in the highway project of the corresponding level.
Of course, the above views are only personal understanding, if colleagues have different views, they can communicate together. At this point, the content of this article will end temporarily, and the original articles related to the profession will be updated from time to time in the future, I hope you will like and support more!
