I would say that a crane truck/mobile crane is the only suitable option.

Handling something that is 16m long with a forklift will be incredibly difficult, if not impossible, to maneuver around. If they also need to be visible, be careful with edge protection and so forth. Otherwise, there will be marks due to their own weight.
We are leaning towards some sort of crane right now. The beams shouldn't be visible, but it feels like an option worth spending a little extra on. Especially considering unloading isn't included upon delivery.

Crane sounds simple, convenient, and quite expensive.

Where in the country is it?

Just outside Hässleholm (Skåne).

16 m will mean expensive transports! Ask the manufacturer to divide the beam into suitable lengths and do as we always do, splice over or between a supporting post.
See post #15. It should be possible to place a splice between the supports. But I'm too new at this to be able to do something like that. Maybe one should hire a consultant who will take on that responsibility.
 
Now I don't know the conditions in this case, but this is how we raised a 370kg I-beam to a height of 5m. It took about an hour to prepare and 15 minutes to lift it.
A 370kg I-beam being hoisted to a height of 5 meters using a pulley system, with scaffolding and wooden supports visible. Worker in high-visibility gear elevates a heavy I-beam onto a scaffold using a pulley system; cloudy sky and a house visible in the background.

When I built the garage, the roof beams arrived with a crane truck along with other building materials. I asked the driver to place them on the walls instead of on the ground. Two men on scaffolding can then move them into the correct position by hand.

We could have built this, but the delivery must come with a crane truck. Otherwise, we need a crane to unload the delivery truck first. Then we might as well do everything with a crane truck.

Will push the supplier to deliver with a crane truck. How long were your roof beams?
 
Finding a crane truck that can transport 16m legally will be difficult.

Why must they be exactly 16m if it's not for a 16m long room without pillars?

There are steel trucks that deliver 24m goods with a crane. But then you have to manage to get such a beast onto the property and also close to where it will be set up. But managing to rent such a truck probably requires some persuasion.

I understand the problem.
The I-beam in my picture was divided into three equal parts that were welded together lying on the concrete slab. In this way, we could carry the beam into place by hand.
 
As mentioned. Why the need for 16m long beams?

Probably to avoid joints and thus an unnecessarily thick beam. The original poster has described that the beam rests on three supports, a joint over the middle support would significantly reduce the utilization of the beam's strength, which would result in a thicker dimension to compensate for that reduction.

Thanks for a detailed description of the situation. That's exactly how it is.

Yeah, but is it tensile load then, or? If it's just weight from above, it shouldn't be much of a problem to have a bearing with a joint, I guess? I'm mostly thinking that 16m long beams are still quite "uncommon" unless you're dealing with purely industrial constructions. I'm just curious.
