Air cleaning for IEQc3.1 Construction IAQ management plan

We are going to apply for 1 point in credit IEQc3.1 but the Contractor is trying to avoid any ventilation during construction: - no natural ventilation - no ventilation by permanent system - no any temporary/portable ventilation units. I have not found any information that air cleaning/ventilation MUST take place and how often. ALL absorptive materials will be protected, for construction works low-VOC materials will be used. Could you please advice if its enough to make house keeping by sweeping (including by vacuum-cleaners), wet mopping and using low-VOC cleaners without any air cleaning? Thank you!
