TL,DR: New installations sometimes don't appear when their production is complete.
Playing a v1. 12. 0 conventional start, but have researched TN tech. The first time I tried to convert conventional industry to a construction factory, the project ran to completion, events window told me the project had completed, but there was no construction factory in the colony (Earth) summary window, and construction capacity had not changed. Built a construction factory from scratch, same result - factory doesn't appear, no change in construction capacity. Tried converting conventional industry to a mine, and that worked normally. From that point forward, could convert to or build construction factories normally.
And just now, completed my first new shipyard complex (commercial), and no new shipyard appeared in the shipyards window.
In all cases, verified that I had sufficient wealth, minerals, and excess population at the start of the project, just before completion of the project, and just after completion of the project. And the missing items aren't showing up on other colonies, in freighter cargo holds, or anywhere else I can find.
