Reach the factory rooftop shown in the screenshot and walk onto the first pressure plate, i.e. the one that is farthest away from the box with the collectible I it. Look up and use the grapple to extend the rope above Batman it will connect both chimneys). Make it over onto the rope, using the hook, and glide towards the next pressure plate. After you land, return to the rope again, using the hook. Glide again, this time towards the last one of the pressure plates. Wait for the box with the Datapack to open and grapple the collectible using the claw.
Note! Due to the bug present in this game, the access to the collectible can be unlocked without the necessity to use the grapple nor the hook. In such a situation, you will be able to collect it straight away.
Start to the North of the collectible, jump off one of the rooftops and glide towards the weakened wall fragment shown in the screenshot. You need to ram through it. After you do, collect the Datapack.
Datapack 10 (My Alibi Nightclub)
You get to visit the My Alibi Nightclub, among others, during the side mission connected with Bird, but you can go there anytime throughout the game. You need to reach the Dance Floor, and make it over to the small balconies under the ceiling, shown in the screenshot, which are located in the North-Western corner of this area (you need to assume the correct position and use the hook). You can now collect the Datapack.
For finding all 10 Datapacks, you receive the audio file connected with Alberto Falcone.
