BOLLARDS AT TERMINALS A & C
Project Highlights / Scope of Work
• Installed 3,600 FT (1,000 quantity) structural steel bollards with architectural stainless steel sleeves
and caps on three levels at two terminals
• Demolished existing sidewalks and repaved with 90,000 SF of new concrete
• Installed 70,000 SF new waterproofing membrane
• Installed three hydraulic-operation security crash gates at separate locations
• Maintain public safety around an active construction site while preserving access to airport terminals
• Coordinate all facets of project at an open, fully operating airport terminal
Through its ongoing initiative to improve safety and security at Newark Liberty International Airport, the Port Authority of NY & NJ contracted Railroad Construction to add a system of bollards at Terminals A & C. These bollards would prevent the possibility of a vehicle being driven directly into the terminal. The final result would be the addition of 3,600 LF of bollards and three vehicle security gates.
Prior to placing the 1,000 structural steel bollards, the existing sidewalks were removed at six locations and 70,000 SF of new waterproofing membrane was laid. The sites were finished with 91,000 SF of new concrete sidewalks.
At Levels 2 and 3 of each terminal, bollards were placed on the existing concrete slab in pre-assembled units of four to five weighing more than two tons each. At Level 1, footings first needed to be constructed using No. 10 and No. 8 rebar. These two locations required that each bollard be placed individually. All bollards were 7’ long with approximately 4‘ embedded underground and a 3’ above ground profile. Finally, architectural stainless steel caps and sleeves were added for aesthetic value.
Three other locations required access to be available for delivery vehicles. At these sites high-tech security crash gates were installed. Each gate unit employs a vertical crash beam from 20’ to 28’ long and a hydraulic operating system. These gates can stop a vehicle moving at speeds up to 50 mph.
One difficult aspect of the work was the requirement that all construction take place at active airport terminals with constant foot traffic. Our work zones were contained at all times and extra security measures were put into place to prevent pedestrians from walking through the site.
