Open facilities.txt in notepad.
Search for "Space Yard"
Copy the whole entry, and paste it twice to make three copies of the spaceyard facility.
Change the names, family numbers and roman numerals to the values mentioned in Fyron's post. Delete the abilities from the SY expansion project facility, and set the Number of Abilities field to zero to match.

Double check to ensure that there are no double blank lines between before or after your new facilities.
Save, and play.
