I can't do much with that. In the past, people would just eliminate the best and worst offer at first. I don't think 5 offers - assuming all companies would be considered for the contract - is excessive. Writing and submitting offers is part of the companies' scope of work, just like their actual work. No one can tell me that this isn't factored in. The problem here is rather that the companies have a ton of work and therefore often refuse to even submit an offer. Unfortunately, the ratio has changed. In the past, the one who paid got the work (exaggerated). Today, as a client, you often feel like a petitioner dependent on the goodwill of the craftsmen and have to be happy when a craftsman takes the time. Of course, correct work should be paid accordingly, but with larger items, I would never get the idea to insist on only 1 or 2 offers on my own. A friend of mine recently talked to a contractor. His statement: "It's crazy right now, you raise prices but still get flooded with orders, that he doesn't even know what to do with all the money anymore." This certainly isn't the case in every company, but it says a lot about the situation in the construction industry...
