3 month performance period vs. Construction

It seems that if a credit could be applicable to part of a construction renovation the performance period should include construction (and as a result the performance period is more than 3 months). This requirement does not appear to be in the reference guide or the credit. For instance the credit SSc3 including IPM, Erosion Control and landscaping with least toxic chemicals. In theory if the performance period is only 3 months and ends with all of the other performance periods you might complete construction without organic landscape methods or erosion control during construction. Following that if you set the correct management protocols for the future, the credit can be achieved? It doesn't seem correct although the credit appears to allow this practice. Thank you for sharing your thoughts!
