Hello, everyone.

This is Enta.

I’ve been getting a bit nervous lately because I’ve been showing up on Google News a lot, but I guess that’s just the nature of sharing information, huh? ^^

 

I’d like to write about “voluntary temporary housing” and “designated temporary housing.”

To put it simply, it's just a matter of whether it's optional or required, lol.

What does "optional" mean?

"Leaving it up to the person's own judgment. Being able to choose for oneself whether to do it or not, and which option to take."

That means you’re free to set up temporary housing wherever you like.

 

For example, when we install ground anchors, we set up scaffolding.

That scaffolding is made from a variety of materials.

Typically, single-tube scaffolding is used. Recently, system scaffolding and wedge scaffolding have become more common.

The materials (types) used to build the scaffolding are different.

Furthermore, the assembly method and structural calculations vary depending on the type of scaffolding material.

However, there is just one small condition.

This is it.

This is the scaffolding width.

The scaffolding width is calculated based on 4.5 meters.

The key point here is that this has already been factored in, so please consider it part of the design.

Those dimensions are the design values. Even for temporary structures. (A remnant from the old days of stacked construction.)

However, if someone asks, “Is it listed in the cost estimate?”—sometimes it isn’t, and sometimes it is. (In the “Remarks” section.)

 

Is this now an unspoken rule? For a standard rotary percussion (skid) unit, it’s 4.5 meters.

For small drilling rigs, 3.0 meters is the standard.

This means that as long as the 4.5-meter scaffold width is maintained with rotary percussion, there are no particular issues with the scaffold specifications.

However, while it is strictly optional, you are required to file a report with the local government, and

You must submit a report on the scaffolding plan and structural calculations and obtain approval.

That doesn't mean everything is free.

 

In a sense, the amount of scaffolding is also optional.

Let's say the design volume specified by the government agency is, for example, 2,000 m³ (kuuryube).

In the past, we used to calculate the total length by measuring all the cross-sections and multiplying them together, but,

Currently, the scaffolding width and length are significantly greater. (Even when measuring only one cross-section.)

 

To put it bluntly, as long as you measure the width of the scaffolding, everything else follows the design. And that’s enough to get approval from the local government. (They’re not very likely to approve additional work for minor variations.)

After all, the only specified dimension is the scaffolding width. (There are regional variations.)

However, in cases where the quantity is clearly greater than originally planned, calculate the estimated quantity in advance and consult with the relevant government office, and

In some cases, it is possible to amend the contract based on the final quantity.

 

Another problem is that general contractors sometimes bill scaffolding contractors for less than the quantities specified in the design, or refuse to approve changes.

Some supervisors say that even though the actual quantity exceeds the planned amount, they can’t report it because the government won’t approve the change.

That’s why there used to be so many scaffolding workers who were crying over it.

For this reason, scaffolding contractors should not simply accept the general contractor’s quantity calculations at face value, but should carefully measure the actual work completed by their own company.

This is an area where our relationship with the general contractor comes into play, so we need to be careful, but,

We recommend that you receive payment for the work as specified in the contract. (This is your right.)

 

Basically, this refers to all temporary structures not included in the design.

For example, single-wall pipes used to support the main rope on a slope are another example.

These are the parts that aren't included in the design but are necessary.

 

The general contractor receives payment from the government for those hidden costs as part of the contract price under the categories of “common temporary facility costs” and “general administrative expenses.”

Roughly 50% of the repair costs

Therefore, it's okay to include the temporary facilities required for construction in the estimate as a subcontractor.

(Well, the general contractor wouldn't actually say something like that to a subcontractor, lol)

 

This is a temporary structure.

I hope you can at least get a sense of the atmosphere.

There are various details to consider, but I hope this gives you a general idea, and that you’ll take the initiative to learn more on your own.

 

See you later.
