Not sure if this is a bug or something I don't know...
I have a shipyard (if it matters, on Ditla IV) Orbital Construction stops at 0 weeks to complete ship, then nothing happens, stuck at 0 week after week. Have tried switching ships, tweaking all military/social/economy emphasis permutations but no go. Shipyard will hold ships in orbit so long as I bring them in, just won't finish building anything.
Cruised around the galciv2 site, but I can't find anyone with a similar problem. The planet is in a great spot and has excellent manufacturing resources, so this is very frustrating!
