The Allen & Shariff Construction division provided General Contracting services to install new head knockers at seven (7) tunnel locations located underneath the BWI Terminal Building within the airfield secure area.

The project included the demolition and removal of the existing head knockers and associated signs and lights. The installation included 9’-6” drilled shafts, filled with concrete to form a 4’ above grade concrete pedestal.
