2 Implement the construction IAQ plan
� Construction IAQ Management Plan;
� Completed IAQ Planning Checklists and evaluations of proposed control measures as
per Appendix C of SMACNA IAQ guidelines for occupied buildings under construction;
and
� Assessment of the duration required for pre-occupancy flush-out as follows:
� Estimation of pre-occupancy flush-out based on likely ambient conditions
according to the project schedule.
� Estimation of pre-occupancy flush-out based on the most onerous ambient
conditions to demonstrate possible maximum impact of project delays.
� Construction IAQ Management Plan, if amended from Design Rating submission;
� Completed IAQ Planning Checklists and evaluations of proposed control measures (if
changed from the Design Rating stage) as per Appendix C of SMACNA IAQ guidelines for
occupied buildings under construction, 2007, 2nd Edition. Provide a summary report
detailing the reasons for each change;
� Time stamped photographs demonstrating the storage and protection of all absorptive
materials from moisture damage; and
� Summary report including:
� IAQ Inspection Checklists as per Appendix D of SMACNA IAQ guidelines for occupied
buildings under construction, 2007, 2nd Edition. Include time stamped
photographic evidence taken by the site supervisors showing each installed control
measure. Weekly photos must be provided at a minimum;
� Time stamped photographic evidence of the building cleaning phase prior to
occupancy;
� Results of the HVAC testing and balancing phase;
� Ambient humidity levels during the building flush-out period, including
demonstrable results of the fresh air delivery rate and duration of both the preoccupancy
and post-occupancy flush-out phases; and
� Demonstrable results of how the air conditioning systems have been reset
according to the building design basis for ongoing operation.
