Comment
If empirical data can be provided, eg side by side comparisons of moist cured vs. non moist cured elements to demonstrate the absence of shrinkage/cracking and to compare concrete strengths, could a clause be added to provide for the removal of the moist curing requirement at the owners discretion? For dimensionally smaller precast elements, moist curing requirements significantly increase production costs while providing nominal to zero benefit to the strength and overall quality. the additional handling required to wet cure newly stripped low strength elements also increases the risk of non visual damage, impacts, cracks etc to occur, negating any potential benefit of wet curing.
