To Be Erected
To Be Built
intransitive verb, godan verb
You know that 建てる is "to build." This is similar to that, but it's the version where you're not doing the building. Something is just getting built. That's why this word is to be erected and to be built. You can recognize that because of the つ, which tells you that two (つ) guys are building the building while you watch. So you're not doing it, they are, and it's just happening.
