Does "a construction was begun" make sense? It sounds weird, I think "a construction began" seems to make sense.
And "it will complete" doesn't make sense? Does it always have to "it will be completed"?
ex)In 2001, the construction of a cultural complex for the Spanish autonomous region of Galicia was begun. According to its architect, it will complete in 2012, taking about 11 years to build.
I am buying a house at the moment, the purchase will complete on the 8th of July. I could say "the purchase will be completed", the meaning would be the same.
ex)According to its architect, it will complete in 2012
I have to admit that there is only one example of "complete" being used in that way in the BNC but, I am buying a house in England at the moment and all the documents from the solicitor talk about completing by a certain date. Perhaps this use is restricted to the real estate/building world.
