[Road of SKYSQUARE-006-] Plans to create a huge pit!!! Civil engineering work requires notification of buried cultural property excavation

We have begun our next plan!!!


The plan is called "Plan to Create a Giant Pit."

In order to maximize the sound field for large-scale outdoor Foley recording, we came up with the idea of digging a huge hole and recording in that huge pit.


These are just ideas to record with the best possible sound, but I won't know the results until I try them, so I'm going to try everything I can think of for now.


But here's where the problem arises.

I can't just dig it up right away because I want to try it.

If excavation is to take place, a " Notification of Buried Cultural Property Excavation (Japanese) " is required, even if the land is owned.

Therefore, it is necessary to document the extent and depth of the excavation and submit the information to the Agency for Cultural Affairs.

I had never done anything like this before, so I started by explaining to the recipient what I wanted to do.


So I went to the cultural center.

Cultural Center

I brought all the documents I could bring with me and explained the situation to the person in charge, who listened to me attentively and taught me how to apply, something that even a beginner could do, so I've summarized it below.


Stakes and ropes

1. Select the location for the drilling site

First, surround the area where you will drive in the stakes and drill holes with a rope.

It is important to make it easy to see where you are digging.

It would be better if the person in charge could immediately understand which areas need to be excavated when they visit the site, rather than having to carefully examine documents.



Adjust the size of the enclosure

2. Adjust the size and make a picture

Once the general outline is determined by driving in the piles, the size is adjusted on site.

This is just a feeling, so I don't know how big it should be (it might not be enough),

We were told that if we wanted to excavate something larger than this at the time of application, we would have to apply again, so it would be better to apply larger.

So I take a larger one.


The application pit size is

Its dimensions are 6m long, 12m wide and 4m high.

The maximum height was determined by assuming it was just before the limit of the excavator's excavation area.

Image from a different angle

3. Prepare diagrams from different angles

We will provide similar image material, but taken from a different angle at the same location.

This will add more clarity, so it's important to create it.


Distance to the border

4. Measure the distance from the boundary line

There are always poles or other markings on land to indicate the boundaries.

You need to measure the distance to this boundary to determine its size.

This is also necessary for the application, so we will measure the size and include it in the documents.


In addition to these, an application form, "Notification of Buried Cultural Property Excavation", will be required.

*This may differ depending on each local government, so the procedure may vary depending on the location.


After preparing all these documents, the application is finally complete!!!

Now that I understand the flow for next time's excavation, it seems like it will go smoothly.

I felt like I should definitely give it a try.

We will continue to proceed with the plan.
