Our contractor would like us to consider attempting an Innovation credit for their use of an aluminum form-work system for all of the tilt-up concrete elements built in the project: the intent of the credit wold be to avoid the more wasteful use lumber in a more traditional form-work system. I wasn't able to find a comparable precedent in the ID credit catalog: is a credit such as this likely to be awarded, or is the intent already addressed elsewhere in LEED v2009, or has this type of system become more standard rather than innovative? Any suggestions/insight are appreciated.
