The initrd image is built as part of the kernel installation process.
There's a postinstallation script which calls /sbin/new-kernel-pkg which
takes care of creating the initrd image and modifying the boot loader.

As for their being 1G of stuff in your BUILD directory, it really just
depends on what you've been building.  You might want to check in there and
see where all of the space is getting utilized and prune as needed, but if
you've been building lots of packages recently, then having that much space
utilized isn't that strange.
