Who is in charge of winning the bid for building engineering materials?

I am in business, and I have been engaged in bidding for many years. I'm too familiar with this kind of thing.

This should be a procurement tender:

A, the tenderer (generally refers to the owner)

Generally, there are bidding offices or bidding teams under the owners. This is the organization that you had a direct relationship with them in the early stage.

Second, the tendering unit (your unit)

If you want to win the bid and only rely on real luck, then I can tell you that the success rate is basically zero.

Some things here are too sensitive to say. Send them to your email if necessary.
