Narrative:

I was the PIC and flying pilot for our ferry flight from iwa. We started to taxi out while it was still dark. Our taxi instructions where east to B to G for runway 12R. I have made this taxi several times in the past from the cessna service center. I expected to taxi straight across the large pad at the end of B and 12R area and hold short of 12R at G. The jepp taxi diagram was just like [I] had remembered the area looking like. As we taxied on east we came to B taxi way and also saw the G taxiway signs. As I continued straight I saw a large triangle shaped new non-taxi area that is not depicted on taxi diagram to my right. I was just past the turn onto B. Instead of making a hard right 130 turn we asked and were granted permission to taxi via new unmarked unnamed taxi way from the holding pad to G. This taxiway was narrow but still wide enough for our aircraft. Everything else was normal. Update jepp taxi chart. The chart revision date is 8/14/2015 and according to google maps there has been construction in this area. I've attached the taxi diagram. I would also attach jepp plate picture but only one attachment is allowed via asap web site.
