Innerbelt ODOT time and materials or lump sum?

These are the wood forms for the new Jersey Barrier - replacing the barrier removed with the old acceleration lane – on the I 90 Innerbelt bridge.  

 

These are custom made-in-place forms, very time consuming prevailing wage activity in one of the most expensive up-in-the-air work environments.

 

Is this work for ODOT being performed on a time and material basis? Or as part of a fixed lump sum contract between Kokosing and ODOT/

 

I’ll bet the former, but that’s just experienced speculation.
