Hello, everyone.

This is Enta.

When working on private construction projects, I often hear people talk about warranty against defects.

A Simple Explanation of the Warranty Against Defects.

A warranty against defects in construction is like insurance that ensures the contractor takes responsibility if there are problems with the work.

That's it.

However, in our case as public works contractors, all materials we use are subject to a permit system or are designated by the government.

Use the materials specified in the design specifications; all other materials must be products from designated manufacturers that comply with JIS standards,

Alternatively, it is a material for which we can issue a certificate of quality that clearly states the product information.

After submitting a quality certificate (mill sheet) and a request for approval, and once the government agency has reviewed the company’s past track record and the product’s performance, a permit for use is issued.

As a result, there are virtually no construction defects in the end. (There may be a few, depending on the type of work.)

Since the government agency approved the materials, the responsibility is transferred to them. (Construction errors are a different story, lol.)

Conversely, in the case of private construction projects, there are almost no specifications regarding materials.

So that’s why people ask, “What about the warranty against defects?”

We responded to the general contractor, explaining that since we use materials equivalent to (exactly the same as) those used in public works projects, our products are designed to last approximately 20 to 50 years.

For that reason, I replied that I could not offer a guarantee.

But looking back now, I don't think there would have been any particular problems even if I had worn it for about two years.

That's because the work I did 10 and 20 years ago is still there.

Come to think of it, maybe I should have been a little—or rather, a lot—more confident?

In fact, even though this is a private-sector project, we do not do anything differently from public-sector projects, so the quality and workmanship are the same as those of public-sector projects.

When undertaking private construction projects in the future, we should probably clarify whether there is any kind of insurance-based warranty against defects or similar coverage.

I also thought that, even when dealing with private-sector clients, rather than proceeding on the assumption that they “don’t understand,” I should aim to communicate in a way that ensures they “do understand.”

Private construction projects really are a great learning experience.

Since we’ve mainly worked on government projects up until now, it’s refreshing to hear feedback from a different perspective.

It looks like I'll have plenty more opportunities to learn in the future.

See you later.
