Dear all,

I am preparing the contractor guidelines for LEED. The project is a large building and there will be two main contractors involved: one at the beginning which will carry out the early works (earthworks and containment), and another contractor which will develop the building construction. 

I was wondering if I should add in the early works contractor the requirements for construction indoor air quality. I believe this does no apply to this stage since all work will be carried out outdoors. But I would like to know how you have addressed this in the past. do you think is ok to only include these requirements in the actual construction works?

Thanks
