Inspection Types & Scheduling Process

Inspections are available Monday-Friday from 9:00 am to 3:30 pm and can be scheduled via phone or email.  Inspections can be scheduled by BDD4 internally or by contractors in the field.  Inspections can be scheduled 24-hours a day and the inspection phone line and inbox will be checked at 7:00 am each morning.  Contractors will have until 7:00 am to schedule an inspection for that day.  If the inspection request is received after 7:00 am it will roll over to the following day.  Contractors can request either an AM or PM inspection, however, this is just a request and not guaranteed.
