ICF_Build,
I should know better than to jump into this mess but here are a couple of points:
--- 40x50 rectangle we'll assume 10' (I don't believe you ever stated height?) would yeild1800 square feet. That's less than 9 cents per square foot to be trained at $150-- you be the judge --- do you need/want to understand what they are doing at a detailed level? -- and if so, it may be worth 9 cents per square foot. Unless you are an experienced builder four hours of training will only give you enough data to hurt yourself.
--- Assuming this rectangle is as simple as stated and ignoring brickledges, arched windows, tall walls, or other not mentioned or other unsung complications this is a two day stack job (for an experienced 4-5 man crew) -- 900 square feet per day --- pour on the third day - at least with Nudura. I don't usually jump out their with brands but you brought it up and Nudura is very fast.
--- Ren mentioned boarding up the corners above, he knows a great deail about ICF but perhaps has not worked with Nudura -- I wouldn't bother boarding up the corners and never have -- I've worked with several installers with over a million square feet (mostly commercial).
--- $750 for three days consulting is about 40 cents per square foot. That's not bad if you pour on the third day.
--- Your bracing rental may be a little high depending on how long you intend to keep them and how far away your Nudura guy is.
good luck , Regards.
P.S. Dana1 -- there are plenty of rocket scientest installers out there! Just ask them
