Steve -
This is a 4.46 bug, but I have no reason to believe that it isn't still a problem in 4.6x. I have shipped several prefabbed PDC's from Strug Home to The Redoubt, along with six engineer regiments, and a small amount of each trans-newtonian resource. Once everything was in place I set the engineer regiments to assembling the prefabbed PDC's on the industry window of the economics screen. Everything appeared to be fine, with a completion date fourteen months in the future. However, after numerous months of game time I checked the progress of the job and noted that it appeared that no work had been completed on the job (amount remaining "1"), and that the completion date still fourteen months in the future. I advanced the time five days, and the amount remaining stayed the same, and the job completion date advanced five days. There are no error messages, or any notations on the event updates screen as to any problems.
To see just how far the problem extends, I cancelled assembly of the PDC and set the engineering regiments to construct 1 industrial capacilty. The info on the industry tab showed that it would take just under 1 year, as the cost was 120 and the six engineer regiments had an annual production of 121.5. However, after advancing the time five days, the screen showed no work completed and the estimated completion date advanced five days.
The engineering units appear to be non-functional.
I have just tested this and it is working as it should. Perhaps there is some reason the engineers are not being picked up as being at that location. Could you confirm that the Engineers are not inside a PDC and that the number of Engineers is shown next to the Industrial Capacity at the top of the Industry tab for that population.

Note that there is the correct number of engineer units displayed on top, along with what I presume is the correct annual production capacity (at least there is a production capacity). One hundred percent of the capacity is directed towards completing the assembly of the PDC, adn the completion date is given as 4-4-2265.
Picture #2 shows the industry tab for The Redoubt on February 1, 2264.

This picture is taken ten days later, and the amount remaining should have been reduced by a small amount, and the estimated completion date should have stayed the same. Instead the estimated completion date has advanced by the same amount that the time has advanced, ten days.
Hopefully that helps.
