Zelda: Tears of the Kingdom's construct factory is a dungeon that you have to visit on your journey through Hyrule. You can't exactly miss it as you come here during the main quest 'Guidance from Ages Past'. However, it's a bit of a head-scratcher, especially as you need to assemble a giant robot by creating its arms and legs. Yes, it sounds like a lot of work, but you know, giant mechs are fun.
Not to worry if you're not ready for this quite yet, you can keep exploring with our Zelda: Tears of the Kingdom lynel locations, Zelda: Tears of the Kingdom armor locations, Zelda: Tears of the Kingdom zonaite, and Zelda: Tears of the Kingdom Pyper guides. Or, for some help on specific missions, we have an article on the Zelda: Tears of the Kingdom six dragons quest to help you out.
Here's our Zelda: Tears of the Kingdom construct factory guide:
