Please excuse me if I missed it but do you conclude from what you have seen so far that Gate Replacement will be a feature of the 2017 bid project?
No. The only Gate Repair that should be done at a minimum is the Anchor Tendons + structural repairs to existing cracks. They don't have enough time to do a "major gate replacement". (assuming this is what your question is asking i.e. Full Radial Gates, Trunnions, Head Structure, or combination thereof etc).
