<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
A question I\u2019ve been hearing a lot lately is, \u201cHow do you handle the inspection of empty bags?\u201d<\/p>\n
<\/p>\n
Back in the day, there was something called the \"loss rate.\"<\/p>\n
Well, I still have some now, lol.<\/p>\n
<\/p>\n
In our construction projects, the design documents are our top priority.<\/p>\n
These are the design documents I often look at.![\"Design](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2021\/02\/9e0e799e4464ce61f7864d335e4a40b9.jpg\")
<\/p>\n
The numbers and ingredients listed here are all there is.<\/p>\n
Based on this, recent spray-applied and injection work is calculated using market rates.<\/p>\n
The market unit price is listed as a \"Construction Package (SP).\"<\/p>\n
<\/p>\n
It's a simple story,A unit price that remains unchanged for one year, even when factoring in all construction losses<\/span><\/strong><\/span>That's the point.<\/p>\n If the quantity changes, the total amount will increase or decrease accordingly. Quantity \u00d7 Market Unit Price = Contract Price<\/p>\n It has nothing to do with whether losses are increasing or decreasing just because the quantity has gone up.<\/p>\n Since this is the market unit price, there is no such thing as a loss rate.<\/p>\n In the past, they used to list the loss rate as \"XX percent.\"<\/p>\n Of course, even now, depending on the type of work, it is still specified.<\/p>\n <\/p>\n In the case of a wooden frame, for example, you start by installing the lath, right?<\/p>\n The market price for sheet piling is 1,760 yen\/m\u00b2 under the conditions of \u201c1,000 m\u00b2 or more (standard), no restrictions, slope cleaning included (no adjustments).\u201d (Aichi Prefecture)<\/p>\n This includes the materials, such as wire mesh and anchor pins.<\/p>\n If the slope being worked on is a clean cut slope and the loss of wire mesh is around 1.2\u5272, it\u2019s perfectly fine to take photos of the quantity received as is.<\/p>\n I think our generation of middle-aged guys, in particular, is pretty sensitive to waste, lol, but back in the day, material waste for fishing nets was 1.4\u5272.<\/p>\n That's why we ordered 1.4 times the usual amount, right?<\/p>\n <\/p>\n The same goes for empty bags. You only need as many empty bags as you\u2019ve used for the job.<\/p>\n \u25a1 Let's assume that a 1,000-meter retaining wall was constructed using 300 units.<\/p>\n That means we need 4,428 empty cement bags with no waste.<\/p>\n Even if there were no losses, 4,428 bags would be sufficient. (I\u2019d guess the actual loss rate is around 10%?)<\/p>\n (Be careful here\u2014if you go below this, the material cost will be lower than the market price, which would be weird lol)<\/p>\n <\/p>\n In my experience, since we switched to market-based pricing, there are almost no inspectors or government officials who bring up issues like losses anymore.<\/p>\n It's the general contractor's supervisor, who's still stuck in the past with those old loss rates, lol.<\/p>\n Now that we're using market unit prices, I think it's fair to say that the concept of a loss rate no longer applies.<\/p>\n This means that as long as you use it within the design specifications, there won't be any problems.<\/p>\n <\/p>\n However, the situation is different when the design documents specify a cost estimation based on the sum of individual components.<\/p>\n Please be especially careful when using special construction methods, as the loss rates from the past may still be applied in some cases.<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.
