Worklabor during construction of Solomon's palace? I am curious about non-Israelites employed in building of Solomon's palace?

Was it common to use such non-Israeli force, especially in position of foreman?
I would say yes, from scripture alone I think we can deduce Solomon used both 'Israeli' and 'non-Israeli' workers as both forced labor (employees) and salves.  

As far as the Hebrew labor force I would say that since Ahishar was in charge of the palace (though at this time it would not have been built) and Adoniram in charge of the of the labor force, the probability that Hebrew's would have filled 'foreman' positions is high.  Since this still was an issue after Solomons death, and it took another 14 years to build the palace, it's likely that it was not constrained to only the temple.

  1 Kings 12:9

  1 Kings 12:14
  he spoke to them according to the counsel of the young men, saying, “My father made your yoke heavy, but I will add to your yoke. My father disciplined you with whips, but I will discipline you with scorpions.”
  
  1 Kings 9:20-22
  All the people who were left of the Amorites, the Hittites, the Perizzites, the Hivites, and the Jebusites, who were not of the people of Israel— their descendants who were left after them in the land, whom the people of Israel were unable to devote to destruction—these Solomon drafted to be slaves, and so they are to this day.....
