A security guard is performing access control at a construction site. A delivery driver arrives without proper identification or a pre-approved delivery schedule. What is the correct procedure?

1. Request the driver's Social Insurance Number for verification purposes.
2. Advise the driver to park off-site and leave the delivery unattended for pickup.
3. Deny entry, request proper identification, verify the delivery with site management, and only then grant access if approved.
4. Grant immediate access to avoid delaying the delivery schedule.
