Hello, everyone.
This is Enta.
A major earthquake struck the Hokuriku region, making for a difficult New Year's holiday.
Another major accident has occurred at Haneda Airport.
It’s been a rough start to the year with all the accidents and disasters, but let’s hang in there!
It seems there are quite a few slippery spots on the mountain, and,
I also sent a LINE message to an acquaintance in the area to check if they were okay.
The way we can show our support from here is by buying local ingredients and contributing financially.
To be honest, I think anything else is just a nuisance.
I plan to buy, eat, donate, and show my support.

Also, it seems there’s been an increase in contractors who take advantage of the situation to put blue tarps on roofs,
I hear they charge hundreds of thousands just to put a blue tarp over the roof.
So, to put it simply,On the roofCalculating the Cost of Laying Down Blue TarpsI'll give it a try.
What would be a reasonable amount?
Please note that this applies only if you hire a professional, so please don't misunderstand.
| #3000: Service Life of Blue Tarps | Approximately 0.26 mm | Approximately 9 to 12 months |
Cost of Materials
Requirements: Two layers of blue tarps (10 m × 10 m), 100 m²; two green nets (10 m × 5 m)
2 blue tarps = 8,000 yen × 2 = 16,000
2 Green Nets = 7,000 yen × 2 = 14,000
Total = 30,000 yen (includes materials and shipping)
Labor costs (Since the work is actually completed in half a day, this amount includes costs for planning and safety equipment.)
Starting at 25,000 yen per person
2 people × 25,000 yen = 50,000 yen
If you add the above together,
80,000 yen per household (for the entire roof of the house)(Price per 100 m²)
Miscellaneous Expenses: 20%
= 80,000 yen × 1.2 ≈ 96,000 yen
Per square meter (960 yen/m²)
Labor costs: 500 yen/m²
Material cost: 520 yen/m²
Overhead: 20% (labor costs)
It probably depends on the size of the company, but,
Approximately 110,000 yen for the entire roof of a house (per 100 square meters)In that case
I think that's a reasonable price.
*Please note that there may be slight variations depending on the number of sandbags.
*If you install the green netting only in certain areas (just the damaged sections), you can keep the cost down.
*The cost will be lower if the affected area is smaller.
*If material costs are cut in half and the area per square meter is reduced, the amount of labor required will also decrease, so the labor rate per square meter could drop to around 20,000.
It's a rough outline, but that's the general idea.
Calculations for Public Works ProjectsSo I hope this is helpful.
However, since the material costs are based on Amazon's prices, they may be too low.
And, to avoid any "he said, she said" situations later on,
If you receive a business card, be sure to obtain evidence—such as having the amount written on the card or recording a voice message on your cell phone.
It's too late once you've been tricked, so please be careful.
See you later.
