Deliveries/Loading Dock


The Loading Dock for Columbia Square is located on the south side of the building. Delivery access is through the alley located in the middle of 12th Street between E and F Streets.

Loading Dock hours are: 6:00 AM - 7:00 PM, Monday through Friday

The Loading Dock is available at other times through coordination with the Property Management Office. There is a 20 minute unloading period for vehicles using the Loading Dock. Parking is not permitted in the loading dock. Once a vehicle has been unloaded, the vehicle must exit the loading dock and park elsewhere.

All delivery personnel will sign in and out with the Loading Dock Officer. The Officer on Duty will then route all deliveries to their destination. Access from the Loading Dock to the West Tower service elevator is via Level P2 of the parking garage.

Please remind all vendors that all deliveries are to be made via the Loading Dock and Service Elevators.


All messengers are required to enter and exit the building via the Loading Dock. After the Loading Dock is closed for the day, messengers needing access are to use the buzzer at the messenger dock off of the 12th Street Loading Dock alley. All messengers must sign in and out with the Loading Dock Officer. Messengers are currently allowed to use the Columbia Square passenger elevators.


Messengers and delivery personnel must use the loading dock located off of 12th Street.

Loading dock and messenger entrances are secured or manned at all times. Upon delivery confirmation by tenant (pre-notification list or phone call to tenant) and photo ID verification, a messenger pass is issued. ID is held and returned when pass is returned.

Freight elevators are secured at all times. Upon issuance of a messenger pass, the messenger is either directed to the tenant’s reception floor, or assisted by security to gain access to the desired floor.
