The frame work of money

I am continuing to learn even as the wheels of progress, because the wheels of progress, have come to a painful halt. It seems that my framing contractor, though well intentioned, does not have a record of actions that line up with his verbal intentions. He has performed in my estimation a day and a half's worth of labor over the past...three weeks.
The weather has been good, very good for days at a time, and yes some poor weather too.
But but but. Butt.
So this is what I have learned. I have learned to start thinking about minimizing my losses and how to properly account for them. For instance, I have advanced my framing contractor money per contractual agreement as well as some extra per his hardship-based request. If I choose to not have him frame the house, I may well end up counting that cash gone.
On the other hand, if I continue to be a party to his evidence-based, lethargic schedule I may end up not having this house on the market at the start of the sales-season (April-May). I will also acrue more interest payments on the construction loan. And, in an attempt to make the sales-season start may generate higher labor costs, adding people as required to complete quicker or contracting out work which I had intended to perform myself.
So, which is the greater loss? I may be able to work out a plan with the framer to work off his credits by assisting me with framing that runs on my schedule and/or have him contribute to the labor required to meet the build schedule on drywall hanging, trim installation, door/window installation, etc.
I dislike confrontation, not completely, but certainly try to avoid it in the least. It would be easy(ier) to let the days pass and deal with the issue, if one still persists, after the Holidays. But but but. This is not a personal, nice, neatly wrapped project that can afford time slippage. It is a business operation that has risk/reward consequences that can break me financially.
So, Dear Framing friend: let's renegotiate.
